  In the liquid medicine agitation unit having the above-described configuration, when the motor 62 of the rotation drive unit 61 is driven, the shaft 64 fixed to the motor 62 rotates with the motor 62. The rotation direction of the motor 62 at this time is referred to as a positive direction. Along with the forward rotation of the shaft 64, the cup 78 fixed to the shaft 64 and the liquid medication bottle 23 held by the cup 78 rotate about the rotation axis L3. The rotation axis L3 forming the central axis of rotation of the liquid medication bottle 23 is along the center line L2 of the liquid medication bottle 23. Here, the center line L2 of the liquid medication bottle 23 means a straight line connecting the opening 23A and the bottom part 23B of the liquid medication bottle 23, and typically, the opening 23A of the liquid medication bottle 23 having a circular shape in plan view. A straight line connecting the center of and the center of the bottom 23B of the liquid medication bottle 23 having a circular shape in plan view.

  In the embodiment illustrated in FIGS. 7 and 8, the liquid medication bottle 23 is disposed at the center of the cup 78. Thus, the center line L2 of the liquid medication bottle 23 and the rotation axis L3 of the rotary drive unit 61 exist in the same straight line. The center line L2 of the liquid medicine bottle 23 may be shifted from the rotation axis L3 of the rotary drive unit 61 in order to stir the liquid medicine 5 more efficiently, and the center line L2 of the liquid medicine bottle 23 may be rotated It may be inclined with respect to the rotation axis L3 of

  With the rotation of the liquid medication bottle 23, the liquid medication 5 stored in the liquid medication bottle 23 follows the rotation direction of the liquid medication bottle 23 and forms the inside of the liquid medication bottle 23 as a cylinder of the liquid medication bottle 23. Flow around the side of the

  After rotating the motor 62 in the forward direction for a predetermined time, the motor 62 is subsequently rotated in the reverse direction which is the opposite direction to the forward direction. The rotational drive unit 61 is provided to generate rotational force in both forward and reverse directions. The liquid medicine supply device 1 may be configured such that the operator operating the liquid medicine supply device 1 can arbitrarily set the rotation direction and the rotation time of the motor 62. For example, after the motor 62 is rotated in the forward direction for 5 seconds to rotate the liquid medication bottle 23 a plurality of times, the motor 62 is rotated in the reverse direction for 5 seconds to rotate the liquid medication bottle 23 in the reverse direction a plurality of times The times of forward rotation and reverse rotation may be equal. Also, for example, the rotation direction of the motor 62 may be set to only the positive direction.

  Along with switching the rotation direction of the motor 62, the rotation direction of the liquid medication bottle 23 is also switched. That is, after rotating the liquid medication bottle 23 in the forward direction, the rotation drive unit 61 rotates the liquid medication bottle 23 in the reverse direction opposite to the forward direction. The turbulence intensity of the turbulent flow in the flow of the liquid medication 5 is increased inside the liquid medication bottle 23 whose rotation direction is switched and is reversely rotated. In addition, a vortex is generated in the flow of the liquid medication 5. The action of the turbulent flow and the vortex causes the liquid medication 5 to be stirred in the liquid medication bottle 23.

  As described above, when the liquid medication bottle 23 is rotated by the rotational driving force generated by the rotation driving unit 61, the liquid medication 5 accommodated in the liquid medication bottle 23 is agitated in the liquid medication supply device 1. Can. Therefore, liquid medication 5 requiring agitation can be efficiently dispensed in a short time using liquid medication supply device 1 of the present embodiment. The cup 78 holding the liquid medication bottle 23 and the liquid medication bottle 23 are integrally rotated in a simple configuration in which the rotary drive unit 61 is added as compared with the conventional device, and the liquid medication 5 is supplied It can be stirred inside. By switching the rotation direction of the liquid medication bottle 23 from the positive direction to the reverse direction, the turbulence strength of the turbulent flow in the liquid medication bottle 23 can be increased, so that the liquid medication 5 can be stirred more efficiently. .

  Further, a tube 34 is disposed in the liquid medication bottle 23 so as to extend from the opening 23A of the liquid medication bottle 23 to the bottom part 23B, and the tube 34 is fixed outside the liquid medication bottle 23. Therefore, the tube 34 rotates relative to the rotating liquid medication bottle 23. The tube 34 functions as a stirrer for the solution 5 because the tube 34 is kept fixed with respect to the solution 5 flowing inside the solution bottle 23 together with the solution bottle 23. That is, by arranging the tube 34 so as to be immersed in the liquid medicine 5 in the liquid medicine bottle 23, the flow of the liquid medicine 5 tends to be turbulent. Therefore, the solution 5 can be stirred more efficiently.

  Next, control in the case where the liquid medication 5 is supplied from the liquid medication bottle 23 to the dosage bottle 2 to perform dispensing will be described. FIG. 9 is a block diagram showing the configuration of the liquid medication supply device 1. As shown in FIG. 9, the liquid medication supply device 1 includes a control unit 90 that controls the overall operation of the liquid medication supply device 1. The touch panel 14 functions as an input unit for inputting various parameters related to the operation of the liquid medicine supply device 1 such as prescription data, and various information such as a patient name and a pharmacist name. The touch panel 14 also functions as a display unit that displays the operating state of the liquid medication supply device 1. The liquid medication supply device 1 may include, as a display unit, a lamp that lights up when an operation failure of the liquid medication supply device 1 occurs, in addition to the touch panel 14.

  The electronic balance 45 detects the weight of the liquid medication 5 supplied to the dosing bottle 2, and inputs the value of the detected weight to the control unit 90. The control unit 90 supplies a predetermined amount of the liquid medication 5 to the dosage bottle 2 while receiving weight data of the liquid medication 5 in the dosage bottle 2 from the electronic balance 45.

  The liquid medication supply device 1 includes a bottle position detection unit 91 that detects the position of each liquid medication bottle 23 in the lower space 12 inside the housing 6. The bottle position detection means 91 may be, for example, various sensors, and the sensor may detect the rotation angle of the liquid medicine bottle holder 32 around the drum axis L1. Since the liquid medication bottle 23 rotationally moves around the drum axis L1 as the rotary drum 21 rotates, the current position of the liquid medication bottle 23 changes frequently. The current position of the liquid medication bottle 23 is accurately detected using the bottle position detection means 91, and data relating to the detected current position of the liquid medication bottle 23 is input to the control unit 90.

  The liquid medicine supply device 1 also includes a communication unit 92 for communicating with an external device and receiving data from the external device. Various parameters relating to the operation of the liquid medication supply device 1 may be input to the control unit 90 by the operation of the touch panel 14 described above, or alternatively, the control unit 90 from an external computer via the communication unit 92. May be input.

  The liquid medication supply device 1 also includes a memory 93 for the control unit 90 to perform calculations. The memory 93 may store data concerning the current position of the liquid medication bottle 23 and data of the liquid medication 5 contained in the liquid medication bottle 23 mounted on the liquid medication supply device 1. The liquid medication supply device 1 also includes a recording medium access unit 94 for mounting a removable recording medium. The data of the liquid medication 5 described above may be stored in various recording media mounted in the recording medium access unit 94, and may be read from the recording medium by the control unit 90 as appropriate.

  The control unit 90 controls the liquid medicine supply device 1 based on the information input from the various devices described above. Specifically, a control signal is transmitted from the control unit 90 to the drum rotation motor 22, the movement motor 39, the pump drive motor 40, the stirring motor 62 for the liquid agent 5, and the lifting device 50. By appropriately operating and stopping, the supply of the liquid medication 5 from the liquid medication bottle 23 to the dosing bottle 2 is performed. After completion of the supply of the liquid medication 5, the printer 17a, 17b constituting the output unit 17 prints a piece of paper on which the dispensing result is printed, and affixing the dosage bottle 2 on which the patient name, pharmacy name, medication time, dosage and the like are printed. Label is output.

  FIG. 10 is a schematic view showing the position of each liquid medication bottle 23 detected by the bottle position detection means 91. As shown in FIG. FIG. 11 is an example of a table showing the current position of liquid medication bottle 23. As shown in FIG. 10, eight liquid medication bottles 23 can be mounted on the liquid medication bottle holder 32 of the present embodiment. The positions at which the eight liquid medication bottles 23 are mounted on the liquid medication bottle holder 32 are indicated by numerals 1 to 8 in FIG. The position indicated by numeral 1 is a position on the foremost side of the liquid medicine supply device 1 where the liquid medicine 5 contained in the liquid medicine bottle 23 is dispensed to the medication bottle, and this position is referred to as a pouring position.

  As shown in FIG. 11, eight liquid medicine bottles A to H are accommodated in eight liquid medicine bottles 23 currently mounted on the liquid medicine supply device 1. At this point, it is assumed that the liquid medication bottle 23 containing the liquid medication A is in the pouring position. The rotating drum 21 is assumed to be rotatable to both sides in the drum circumferential direction. The liquid medication bottle holder 32 is rotatable in both clockwise and counterclockwise directions. Therefore, the time to move the liquid form B and the liquid form H disposed next to the liquid form A currently at the pouring position to the pouring position is equal.

  In the following example, it is assumed that the time for rotating the liquid medication bottle holder 32 by 45 °, that is, the time required for moving the next liquid medication B to the pouring position when the liquid medication A is currently at the pouring position, It is 3 seconds. In this case, it takes a moving time in proportion to the moving distance of the liquid medicine bottle 23, and as shown in FIG. 11, the moving time to the pouring position of liquid medicine C and liquid medicine G next to liquid medicine A two. Is 6 seconds, and similarly, the moving time from the solution A to the pouring position of the solution E which is most separated in the rotational direction is 12 seconds.

  FIG. 12 is an example of a table showing the liquid medication 5 requiring agitation. Among the eight types of liquid medications A to H mounted on the liquid medication supply device 1, the liquid medication B and the liquid medication E are agitation-required liquids that require agitation before being supplied to the dosing bottle 2. In the present embodiment, the liquid agent that requires stirring is a liquid agent that becomes inhomogeneous due to settling or the like when left to stand for a long time. As a solution which needs stirring, for example, a suspension or an emulsion can be mentioned. On the other hand, liquid medications A, C, D and F to H are agitation-free liquid medications that do not require stirring before being supplied to the dosing bottle 2. The liquid agent which does not require stirring is a liquid agent which can maintain a homogeneous state even after standing for a long time.

  As shown in FIG. 12, the required stirring time of liquid medication B and liquid medication E is 10 seconds, and based on this required stirring time, the forward rotation time of the motor 62 for stirring (5 seconds) And the reverse rotation time (5 seconds) are determined. In FIG. 12, the required stirring time of liquid formulations B and E requiring stirring is the same, and the required stirring time is fixed, but the required stirring time may be different for each type of liquid formulation 5.

  FIG. 13 is an example of a prescription table indicating the type of liquid medication 5 to be supplied to the dosing bottle 2. In this example, three types of liquid medications 5 to be taken by the patient are mixed and supplied to the dosing bottle 2 according to the prescription of the doctor. The prescription table stores data on the type of liquid medication and the amount of liquid medication to be dispensed. In the case of this example, 20 ml of solution B, 30 ml of solution C and 40 ml of solution G are supplied. Each data related to the prescription table may be input to the control unit 90 using the touch panel 14 as described above, or may be input to the control unit 90 from an external computer via the communication unit 92. .

  FIG. 14 is a flow chart of the liquid medicine supply processing from the liquid medicine bottle 23 to the dosing bottle 2 using the liquid medicine supply device 1 according to the present embodiment. As shown in FIG. 14, in the liquid medicine supply process of the present embodiment, first, the order of pouring out the liquid medicine 5 is determined in step S100, and then the actual pouring is performed in step S200. In the present specification, a sequential order in which each of the liquid medications 5 contained in the plurality of liquid medication bottles 23 is sequentially and successively fed from the liquid medication bottle 23 to the dosing bottle 2 is referred to as a feeding order. In this supply order, the order in which the respective solutions 5 are supplied is referred to as the supply order.

  FIG. 15 is a flowchart showing details of step S100 for determining the order shown in FIG. The supply order of the plurality of solutions 5 and the supply order of each solution 5 are determined according to the steps described below. First, in step S110, the number of medicines to be poured into the dosing bottle 2 is acquired. At this time, the control unit 90 refers to the prescription table shown in FIG. 13 and recognizes that three types of liquid medications, liquid medication B, liquid medication C and liquid medication G, are dispensed.

  Subsequently, in step S120, the current position of the liquid medication bottle 23 at the stage of acquiring the number of medicines for dispensing is acquired. At this time, the control unit 90 refers to the table shown in FIG. 11 where the current position of the liquid medication bottle 23 is recorded based on the detection result of the bottle position detection means 91, and the liquid medication at the current pouring position And the current position of the liquid medication bottle 23 containing the three liquid medications B, C, and G to be poured out. Subsequently, in step S130, based on the current position of the liquid medication bottle 23 acquired in step S120, the control unit 90 calculates the moving time of each liquid medication bottle 23 to the pouring position. In the case of this example, since the liquid medication A is at the pouring position, as shown in FIG. 11, the traveling time to the pouring position of the liquid medication B is 3 seconds, and the movement to the pouring position of the liquid medication C The time is 6 seconds, and the traveling time to the pouring position of the liquid medicine G is 6 seconds.

  Subsequently, in step S140, the stirring time of liquid medication 5 is calculated. The control unit 90 compares the prescription table shown in FIG. 13 with the table of the liquid medication requiring agitation shown in FIG. 12, and the water which the liquid medication B poured out in the present dispensing process requires agitation It is calculated that it is an agent and that the required stirring time is 10 seconds.

  Subsequently, in step S150, the pouring time of each liquid preparation is calculated. The control unit 90 refers to the prescription table of FIG. 13 to recognize the pouring amounts of the three types of liquid medications B, C and G, and injects the liquid medication 5 per unit time by the pump drive motor 40. Each pouring time of liquid medicines B, C, and G is computed based on the amount of discharge. In the case of this example, the pump drive motor 40 is designed to transfer 10 ml of the liquid medication 5 in one second, and the pouring time is proportional to the pouring quantity of the liquid medication 5. In this case, the pouring time of liquid medication B is 2 seconds, the pouring time of liquid medication C is 3 seconds, and the pouring time of liquid medication G is 4 seconds.

  Subsequently, in step S160, the total supply time (hereinafter referred to as TOTAL dispensing time) required to supply the three types of liquid medications B, C, G to all the dosing bottles 2 is calculated.

  FIG. 16 is a flowchart showing details of step S160 for calculating the TOTAL pouring time. The method of calculating the TOTAL pouring time will be described in detail with reference to FIG. First, in step S161, the variable i is set to 1, and the variable total is set to 0.

  Here, the variable i indicates a number given to the liquid medicine to be poured out, and can take an integer value of 1 or more. For example, in accordance with the prescription table shown in FIG. 13, temporary numbering is performed such that the liquid medicine B is No. 1, the liquid medicine C is No. 2 and the liquid medicine G is No. 3. The variable total indicates time.

  It should be noted that the variable i does not indicate the supply order when the actual dispensing is performed in step S200. As described later, in order to determine the feeding order when actual pouring is performed, the TOTAL pouring time for all possible feeding orders is calculated and then the optimum feeding order among them (ie, the feeding order). , The order of delivery in which the TOTAL pouring time is shortest. In FIG. 13, the liquid medicine B is numbered 1, the liquid medicine C is numbered 2, and the liquid medicine G is numbered 3. For example, these are numbered in the order in which the doctor wrote the prescription, and For example, it is only the order in which the data was input. In determining the TOTAL dispensing time, the solutions B, C, and G are given arbitrary numbers 1 to 3, and combinations of a total of six dispensing orders are tried. Similarly, if, for example, two liquid drops are listed on the prescription table, a combination of a total of two dispensing orders is tried, and if, for example, four liquid drops are listed on the prescription table, A total of 24 combinations of dosing order are tried.

  Returning to FIG. 16, subsequently, in step S162, the stirring time and moving time of the first medicine, liquid medication B, are compared. At this point, since the variable total is 0, it is sufficient to compare only the stirring time and the moving time of liquid medication B. In the case of this example, as shown in FIG. 12, the necessary stirring time of liquid medication B is 10 seconds, and as shown in FIG. 11, the moving time for moving liquid medication B to the pouring position is 3 seconds. The time is longer. That is, while the liquid medicine B is moved from the current position to the pouring position, the stirring of the liquid medicine B is not completed, the stirring time of the liquid medicine B is limited, and the variable total is governed by the stirring time of the liquid medicine B . Therefore, the process proceeds to step S163, and the sum (10 seconds + 2 seconds = 12 seconds) of the stirring time of the liquid medicine B and the pouring time is set as a variable total.

  Since the time required to dispense the first liquid medicine B has been calculated in step S163, the process advances to step S165 to add 1 to the variable i. In other words, the pouring time for the second liquid medicine C will be examined next. In the next step S166, it is determined whether the variable i has exceeded the number of prescribed drugs in order to determine whether or not the pouring times for all prescribed drugs have been calculated. In this example, since the variable i at this point is 2, the number of prescribed medicines is 3, and the variable i is less than or equal to the number of prescribed medicines, the process returns to step S162.

  In the second step S162, the stirring time of the second medicine, liquid medication C, and the sum of the current variable total and the movement time of the liquid medication C are compared. In the case of this example, since the liquid medicine C is a liquid medicine which does not require stirring, the stirring time is zero. That is, the sum of the current variable total and the transfer time of the liquid medicine C is longer than the stirring time of the liquid medicine C. Therefore, the sum of the variable total at the present time and the movement time of the liquid medicine C becomes rate-limiting, and the sum of the variable total at the current time and the movement time of the liquid medicine C governs the new variable total. Therefore, the process proceeds to step S164, and the sum of the variable total at the present time, the transfer time of the liquid medicine C, and the pouring time of the liquid medicine C is set as a new variable total.

  FIG. 17 is a table showing the current position of the liquid medication bottle 23 when the liquid medication B is in the pouring position. As a result of rotational movement of the rotary drum 21 from the position of the table shown in FIG. 11 to change the position of the liquid medication bottle 23, the liquid medication B is in the pouring position at the present time. Therefore, the moving time required to move the second liquid medicine C to the pouring position is 3 seconds as shown in FIG. Therefore, the moving time of the liquid medicine C and the pouring time (3 seconds + 3 seconds = 6 seconds) are added to the variable total (12 seconds) at the current point, and the new variable total becomes 18 seconds. In this way, the time required to dispense the second liquid medicine C is calculated.

  Subsequently, 1 is added to the variable i in step S165, and the variable i is set to 3. Subsequently, in step S166, the value of the variable i is compared with the number of prescribed medicines, and since both the variable i and the number of prescribed medicines are 3 and the variable i is less than the number of prescribed medicines, the process returns again to step S162.

  In the third step S162, the stirring time of the liquid medicine G which is the third medicine is compared with the sum of the variable total at the present time and the moving time of the liquid medicine G. In the case of this example, since the liquid medicine G is a liquid medicine which does not require stirring, the stirring time is zero. Therefore, the process proceeds to step S164, and the sum of the variable total at the present time, the transfer time of the liquid medicine G, and the pouring time of the liquid medicine G is set as a new variable total.

  FIG. 18 is a table showing the current position of the liquid medication bottle 23 when the liquid medication C is in the pouring position. As a result of the rotational movement of the rotary drum 21 from the position of the table shown in FIG. 17 and the change of the position of the liquid medication bottle 23, the liquid medication C is in the pouring position at the present time. Therefore, the moving time required to move the third liquid medicine G to the pouring position is 12 seconds as shown in FIG. Therefore, the moving time of the liquid medicine C and the pouring time (12 seconds + 4 seconds = 16 seconds) are added to the variable total (18 seconds) at the current point, and the new variable total becomes 34 seconds. In this way, the time required to dispense the third liquid medicine G is calculated.

  Subsequently, in step S165, 1 is added to the variable i, and the variable i is set to 4. Subsequently, in step S166, the value of variable i is compared with the number of prescribed medicines. At this point, the variable i is 4, the number of prescribed drugs is 3, and since the variable i exceeds the number of prescribed drugs, the calculation of the TOTAL injection time is ended.

  FIG. 19 is a timing chart showing the TOTAL dispensing time in the case of dispensing in the order of solutions B, C and G. As described above, stirring and pouring out of solution B, transfer and pouring of solution C, and transfer of solution G, since the stirring time of solution B is longer than the transfer time of solution B. And by adding the time required for pouring, it is calculated that the TOTAL pouring time in the case of pouring in the liquid formulations B, C and G in order is 34 seconds.

  In the case of this example, since the number of medicines to be dispensed is three, a total of six combinations of the order of combination of the liquid medicine 5 into the dosage bottle 2 by switching the order of the liquid medicines B, C and G are considered. Be The TOTAL pouring time is calculated in the same manner as described above for all of the six feeding orders.

  For example, it is also possible to calculate the TOTAL dispensing time in the case of dispensing in the order of liquid medications G, B, C next. In this case, referring to FIG. 16 again, since the first drug, liquid medication G, does not need to be stirred before being supplied to the dosing bottle 2, the time required for pouring the liquid medication G is water It is the sum (6 seconds + 4 seconds = 10 seconds) of the travel time of the agent G and the pouring time.

  The second medicine, liquid medication B, requires stirring for 10 seconds. Here, the agitation of the liquid medicine B is performed between a moving time for moving the liquid medicine G which does not require stirring to the pouring position and a pouring time for pouring the liquid medication G. The liquid medication bottle 23 containing the liquid medication B rotationally moves about the drum axis L1 while the liquid medication B is being stirred.

  While the controller 90 shown in FIG. 9 supplies the liquid medication G to the dosing bottle 2 and rotates the rotary drum 21 as a bottle position changer to change the position of the liquid medication bottle 23, the liquid medication agitation Activate the part and stir the solution B. In the supply order of supplying each of the liquid medications 5 contained in the plurality of liquid medication bottles 23 from the liquid medication bottle 23 to the dosage bottle 2, the control unit 90 The liquid medicine B is stirred until it reaches, that is, until the rotational movement of the rotary drum 21 for moving the liquid medicine bottle 23 containing the liquid medicine B to the pouring position is started. The control unit 90 starts supplying the solution B to the dosing bottle 2 after the supply of the solution G to the dosing bottle 2 is completed, and the solution G whose feeding order is earlier than the solution B is started. While the solution is supplied to the dosing bottle 2, the solution B is stirred.

  In the second step S162, the stirring time of liquid medication B is compared with the sum of the variable total at the present time and the moving time of liquid medication B. FIG. 20 is a table showing the current position of the liquid medication bottle 23 when the liquid medication G is in the pouring position. Referring to FIG. 20, the moving time required to move the second liquid medicine B to the pouring position is 9 seconds as shown in FIG. The variable total at the present time is the sum of the transfer time of the liquid medicine G, which is the first medicine, and the pouring time. That is, in step S162 of the second time, the control unit 90 compares the first liquid medicine supply time required for the supply of the liquid medicine G with the second water medicine agitation time required for the stirring of the liquid medicine B.

  Here, the first liquid medicine supply time is from the liquid medicine bottle 23 as the first bottle containing the liquid medicine G which is the first liquid medicine to be poured first to the supply of the liquid medicine G to the dosing bottle 2 It is the time it takes. The second liquid agent stirring time is the time required for stirring the liquid agent B, which is the second liquid agent to be poured out second. Further, the control unit 90 compares the subtotal time obtained by adding the first liquid medicine supply time and the position change time required to change the position of the liquid medicine bottle 23 with the second liquid medicine agitation time.

  When the stirring time (10 seconds) of liquid medication B is compared with the sum of the variable total at the present time and the moving time of liquid medication B (10 seconds + 9 seconds = 19 seconds), the latter is larger. Therefore, the process proceeds to step S164 to add the moving time of the liquid medicine B and the pouring time (9 seconds + 2 seconds = 11 seconds) to the variable total (10 seconds) at the current point, and the new variable total becomes 21 seconds. As a result, the time required to dispense the second liquid medicine B is calculated.

  Since the third drug, liquid drug C, does not require stirring, in step S164, the sum of the variable total at the present time, the transfer time of liquid drug C, and the pouring time of liquid drug C is newly added Variable total. Referring to FIG. 17, the moving time required to move the third liquid medicine C to the pouring position is 3 seconds. Therefore, the moving time of the liquid medicine C and the pouring time (3 seconds + 3 seconds = 6 seconds) are added to the variable total (21 seconds) at the current point, and the new variable total becomes 27 seconds. In this way, the time required to dispense the third liquid medicine G is calculated.

  FIG. 21 is a timing chart showing the TOTAL dispensing time in the case of dispensing in the order of solutions G, B and C. As described above, the sum of the transfer time and pouring time of the first solution G and the transfer time of the second solution B is longer than the stirring time of the solution B. Therefore, by adding the time required for movement and pouring of liquid medication G, movement and pouring of liquid medication B, and movement and pouring of liquid medication C, the liquid medications G, B and C are sequentially poured out. The TOTAL pour time for the case is calculated to be 27 seconds.

  FIG. 22 is a timing chart showing the TOTAL dispensing time in the case of dispensing in the order of solutions G, C and B. Solution B requiring agitation is poured out third. Since the stirring of liquid medication B is started simultaneously with the start of transfer of the first liquid medication G, the stirring of liquid medication B is already completed by the end of the pouring of the second liquid medication C. After the stirring of the liquid medication B is completed, the control unit 90 starts supplying the liquid medication B to the dosing bottle 2 with a lapse of time. Therefore, by adding the time required for moving and pouring out solution G, transferring and pouring out solution C, and moving and pouring out solution B, the drops of solution G, C and B are sequentially dispensed. The TOTAL pouring time for the case is calculated to be 30 seconds.

  Similarly, the TOTAL dispensing time in the case of dispensing in order of liquid medications B, G, C, in order of liquid medications C, B, G, in order of liquid medications C, G, B is calculated. That is, six TOTAL pouring times, which are all combinations for sequentially pouring three types of liquid medications B, C, and G, are calculated.

  Referring back to FIG. 15, next, in step S170, based on the calculation results of the six TOTAL dispensing times described above, the dispensing order when actually dispensing the liquid medication 5 into the dosing bottle 2 is decide. Specifically, among the six TOTAL dispensing times, the order in which the TOTAL dispensing time is shortest is selected, and the order is determined by adding each of the solutions 5 contained in the plurality of solution drops 23 It is determined as the supply order of feeding from the bottle 23 to the dosing bottle 2. Thus, the supply order of supplying each liquid medication 5 (that is, liquid medications B, C and G) to the dosing bottle 2 is determined, and step S100 shown in FIG. 14 is completed.

  By minimizing the amount of rotation of the rotary drum 21, it is possible to minimize the time required for the movement of the liquid medication bottle 23 to the pouring position. The control unit 90 supplies the plurality of kinds of liquid medications 5 contained in the plurality of liquid medication bottles 23 to the dosing bottle 2 so that the supply order of the stirring necessity liquid medications comes later than the supply order of the stirring unnecessary medications. Set the supply order. As a result, it is possible to shorten the time that affects the TOTAL pouring time, out of the time required for stirring the stirring-necessitating solution. Therefore, it is possible to reduce the time required to carry out all the dispensing of a plurality of liquid formulations.

  Subsequently, the supply of the solution 5 to the dose bottle 2 is performed from each of the plurality of solution bottles 23 containing the solution 5. FIG. 23 is a flow chart showing the details of step S200 for dispensing the liquid medication 5 shown in FIG. Referring to FIG. 23, first, in step S210, it is determined whether the plurality of liquid medications 5 supplied to the dosing bottle 2 contain a medicine that requires agitation. If there is a watering agent requiring stirring, the process proceeds to step S220, the stirring operation flag is set, and then the process proceeds to step S230. If there is no medicine that needs to be agitated, step S220 is skipped and the process proceeds directly to step S230.

  FIG. 24 is a flowchart showing a subroutine for stirring the solution 5. The subroutine shown in FIG. 24 starts at the same time as activation of the liquid medicine supply device 1 and is always executed. As shown in step S221, whether or not the stirring operation flag is set is constantly monitored, and while the stirring operation flag is not set, a standby state in which an instruction is awaited is entered.

  When the stirring operation flag is set in step S220 shown in FIG. 23, it is determined in step S221 that the stirring operation flag is set, and the process proceeds to step S222. In step S222, the control unit 90 drives the motor 62 for stirring the liquid medication 5 to rotate the liquid medication bottle 23. Turbulence is generated in the liquid medication bottle 23 by rotating the liquid medication bottle 23 in both forward and reverse directions, whereby the liquid medication 5 in the liquid medication bottle 23 is agitated. Stirring is continued until it is determined in step S223 that the stirring is complete. The determination of the completion of the stirring is performed, for example, by detecting whether the driving time of the motor 62 has exceeded a predetermined time with a timer.

  When the stirring operation flag is set in step S220, the determination in step S221 becomes YES, and the process proceeds to step S222 and the stirring is started. When one prescription includes a plurality of solutions 5 requiring agitation, the agitation operation flag of the plurality of solutions 5 is simultaneously set, and the agitation of the plurality of solutions 5 is simultaneously started.

  If it is determined that the stirring is completed, the motor 62 is stopped, and then the process proceeds to step S224 where the stirring operation flag is cleared. The subroutine of FIG. 24 is then returned to return to the standby state again.

  Although the subroutine shown in FIG. 24 may be always executed simultaneously with the device activation as described above, the subroutine start flag may be set after determining the supply order of liquid medication 5, and in this case, the required plural types The sub-routine may be ended after all of the solutions 5 have been supplied to the dosing bottle 2.

  Referring back to FIG. 23, next, in step S230, it is determined whether it is the order of dispensing of the medicine that requires agitation. If it is the supply order of the stirring-necessitating liquid agent, it is then determined in step S240 whether the stirring operation flag is cleared. That is, when it becomes the supply order of the stirring-necessitating liquid agent, the liquid agent 5 is already stirred according to the subroutine shown in FIG. 24. As a result, in step S224, it is determined whether the stirring operation flag is cleared. . If the stirring operation flag is not cleared, since the stirring is not completed yet, the process waits until the stirring is completed and the stirring operation flag is cleared. If it is determined that the stirring operation flag is cleared, the process proceeds to step S250.

  If it is the supply order of the stirring unnecessary liquid medicine which does not need stirring, since pouring of the liquid medicine 5 is possible irrespective of the stirring operation flag, it proceeds from step S230 directly to step S250. Subsequently, in step S250, the liquid medication bottle 23 containing the liquid medication 5 to be poured is moved to the pouring position, and thereafter, the liquid medication 5 is poured from the liquid medication bottle 23 to the dosing bottle 2.

  Here, as soon as the stirring operation flag is set in step S220, the stirring is started in step S222. In addition, after the stirring operation flag is set in step S220, if the liquid medication 5 supplied to the dosing bottle 2 first is a stirring unnecessary liquid medication that does not require stirring before being supplied to the dosing bottle 2, step S250 immediately. Transfer of the liquid medication bottle 23 is started. While the rotary drum 21 changes the position of the liquid medication bottle 23, the control part 90 operates the rotation drive part 61 that constitutes the liquid medication stirring part to stir the liquid medication 5 in the liquid medication bottle 23.

  Subsequently, the process proceeds to step S260, where it is determined whether all target solutions 5 described in the prescription have been supplied to the dosing bottle 2, and if not completed, the process returns to step S230. If all of the liquid medication 5 has been dispensed, the supply of the liquid medication 5 to the dosing bottle 2 is complete, and step S200 shown in FIG. 14 is complete.

  As described above, in the liquid medicine supply device 1 of the present embodiment, the liquid medicine 5 that requires agitation before being supplied to the dosage bottle 2 is supplied while the other liquid medicine 5 is supplied to the dosage bottle 2; Or, while changing the position of liquid medication bottle 23, it is agitated. By adding the stirring time of the stirring-necessary solution to the pouring time and / or transfer time of the other solution 5, the time for only stirring can be shortened, and typically the time for only stirring is eliminated. it can. Therefore, the pouring time of the liquid medicine 5 can be shortened.

  In addition, the supply order of supplying plural kinds of liquid medications 5 contained in a plurality of liquid medicine bottles 23 to the dosing bottle 2 is a liquid medicine where the supply order of the liquid medication B which is a stirring-necessary liquid medication is a stirring unnecessary liquid medication It may be set to be later than the supply order of G. Alternatively, the supply order may be preset, such as set in accordance with the order in which the doctor wrote the prescription, and the control unit 90 may not change the supply order. Even if the supply order is set in advance and the solution B requiring agitation is set to the first supply order, as shown in FIG. 19, the stirring time and the transfer time of the solution B should be overlapped. By this, it is possible to shorten the time for only stirring the liquid medicine B. Therefore, the pouring time of the liquid medicine 5 can be shortened.

Second Embodiment
FIG. 25 is a timing chart showing the TOTAL pouring time according to the second embodiment. In the second embodiment, an example will be described in which the liquid medication 5 is supplied to the dosage bottle 2 according to a prescription for supplying 50 ml of each of the five liquid medications P, Q, R, S and T. The pouring times of the liquid formulations P, Q, R, S and T are all equal to 5 seconds. At this time, the liquid medication bottles 23 containing the five kinds of liquid medications P, Q, R, S and T are arranged adjacent to each other on the liquid medication bottle holder 32, and therefore each liquid medication bottle It is assumed that the traveling time to the 23 dispensing positions is 3 seconds.

  Also, among the five types of liquid medications P, Q, R, S and T, only the liquid medication T is a stirring-necessary liquid medication that requires stirring before being supplied to the dosing bottle 2, and the other liquid medications P, Q , R and S are all agitation-free liquids which do not require agitation before being supplied to the dosing bottle 2.

  As described with reference to FIG. 23, since the stirring operation flag is set at the start of supply of the liquid medication 5 to the dosing bottle 2, the stirring of the liquid medication T simultaneously with the start of transfer of the liquid medication P as shown in FIG. Has been started. After the solution T is stirred for 10 seconds, the stirring is stopped. In addition, after the liquid medication T is stopped for a predetermined time (10 seconds in this example), stirring for 10 seconds is performed again.

  In this way, if the liquid T, which is a liquid that needs to be stirred, is repeatedly stirred before being supplied to the dosing bottle 2, the time when the liquid T will be supplied, that is, the liquid bottle 23 containing the liquid T. The liquid medicine T can be stirred in a time zone closer to the time when the movement of the water to the pouring position is started. Therefore, since the sedimentation of the suspension component contained in the liquid medicine T can be more reliably suppressed to the bottom of the liquid medicine bottle 23, the liquid medicine T in a more uniform state can be supplied to the dosing bottle 2.

Third Embodiment
FIG. 26 is a timing chart showing the TOTAL pouring time according to the third embodiment. The third embodiment is an example in which five types of liquid medications P, Q, R, S and T are supplied to the dosing bottle 2 as in the second embodiment described above. In the third embodiment, as shown in FIG. 26, from the start of transfer of the liquid medicine P to the end of pouring of the liquid medicine S, that is, the stirring of the liquid medicine T is continuous until the supply order of the liquid medicine T is reached. It can be continued.

  According to the dispensing process described in the third embodiment, as in the second embodiment, the liquid medication T can be stirred in a time zone closer to the supply start time to the dosing bottle 2, and the water of the suspension component contained in the liquid medication T The liquid medicine T in a more uniform state can be supplied to the dosing bottle 2 because the sedimentation to the bottom of the medicine bottle 23 can be more reliably suppressed.

Embodiment 4
FIG. 27 is a timing chart showing the TOTAL pouring time according to the fourth embodiment. In the fourth embodiment, a prescription in which two kinds of liquid medications B and H arranged according to the table shown in FIG. 11 are supplied, the pouring quantity of the liquid medication B is 20 ml, and the pouring quantity of the liquid medication H is 50 ml. An example in which the liquid medication 5 is supplied to the dosing bottle 2 will be described in accordance with FIG. The pouring time of liquid medication B is 2 seconds, and the pouring time of liquid medication H is 5 seconds. As shown in FIG. 12, liquid medication B is a stirring-required liquid medication and liquid medication H is a stirring-free liquid medication. Further, as shown in FIG. 27, it is assumed that the prescription for supplying the liquid medications B and H is performed three times consecutively.

  In this case, the liquid preparation B which needs to be stirred before being supplied to the dosing bottle 2 may be stirred only in the first of three consecutive formulations. A short time after the liquid medicine B is stirred in the first formulation, the liquid medicine B is dispensed according to the second and third prescriptions. In the second and third prescriptions, it is considered that time has not elapsed since the liquid medication B was stirred in the first prescription and the liquid medication B has already been stirred. Although the liquid medicine B is a stirring-necessary liquid medicine in the first formulation, the liquid medicine B can be treated as a stirring-free liquid medicine in the second and third prescriptions. Therefore, in the second and third formulations, re-stirring of liquid medication B is unnecessary, and it is possible to shorten the required time of stirring time of liquid medication B.

  In this way, it is possible to shorten the TOTAL dispensing time of liquid medications B and H in the second and third prescriptions. In the second and third prescriptions, the control unit 90 starts supplying the liquid medicine B to the dosing bottle 2 after a lapse of time after the stirring of the liquid medicine B. Such a dispensing process is particularly effective for shortening the TOTAL dispensing time, when all the solutions contained in the prescription are agitation requiring solutions.

Fifth Embodiment
FIG. 28 is a timing chart showing the TOTAL pouring time according to the fifth embodiment. Embodiment 5 is an example similar to Embodiment 1 described above in which three types of liquid medications B, C and G are supplied to a dosing bottle 2. Stirring Depending on the type of the water stimulant, it is possible to keep the water repellent 5 uniform for a long time (for example, 10 hours or more) after stirring. In the case of such a liquid preparation, if stirring is carried out only once, for example, only when the liquid medicine supply device 1 is started during the day, no stirring is necessary at the time of actual pouring thereafter. In the fifth embodiment, it is assumed that liquid medication B is a kind of liquid medication that can maintain sufficient uniformity by stirring once a day.

  Therefore, as shown in FIG. 28, by stirring the liquid medicine B in advance, the liquid medicine B is treated as a stirring-free liquid medicine that does not require stirring before being supplied to the dosing bottle 2 at the time of actual pouring. As a result, the time required for TOTAL can be reduced by the stirring time of solution B. After the stirring of the liquid medication B is completed, the control unit 90 starts supplying the liquid medication B to the dosing bottle 2 with a lapse of time. In this way, the TOTAL dispensing time when dispensing in the order of solutions B, C, and G can be significantly reduced as compared with FIG.

  In the above-described embodiments, in the configuration in which the liquid medication bottle 23 is movable in the liquid medication supply device 1, the TOTAL dispensing is performed in consideration of the moving time for moving the liquid medication bottle 23 to the dispensing position. The time was calculated. In the configuration in which the liquid medication bottle 23 does not move within the liquid medication supply device 1, the TOTAL dispensing time may be calculated without considering the movement time of the liquid medication bottle 23. That is, the TOTAL pouring time may be calculated by appropriately adding the pouring times and the stirring times of the plurality of liquid formulations 5.

  Although the embodiments of the present invention have been described above, the configurations of the respective embodiments may be combined as appropriate. Further, it should be understood that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the present invention is shown not by the above description but by the scope of claims, and is intended to include meanings equivalent to the scope of claims and all modifications within the scope.
