Description

  The present invention relates to a stopper made of an elastic material disposed at the mouth of a medical container, and a medical container including the stopper.

  Conventionally, a plug made of an elastic material (rubber material, elastomer material) is disposed at the mouth of a medical container such as a drug container or an infusion container, and the mouth is liquid-tight and air-tightly sealed by the plug. (For example, see Patent Document 1 below). In the medical container, for example, a diluting liquid (for example, physiological saline, Ringer's solution, etc.) is stored in advance, and one or more drugs are injected into the medical container by inserting a needle into the stopper. Mix the liquid and medicine in the medical container. This operation is called “mixed injection”. After the mixed injection, in order to connect the infusion line to the medical container, the bottle needle provided at the end of the infusion line is inserted into the stopper. The plug body is provided with a concave mixed dimple as a location where the needle is inserted during the mixed injection, and a concave discharge dimple as a location where the bottle needle is inserted when the infusion line is connected.

  When multiple types of drugs are mixed, it is necessary to pierce the stopper many times. If the needle is pierced many times in the same part of the stopper, there is a concern that the sealing function may be deteriorated. For this reason, the plug body is provided with a plurality of mixed injection dimples to reduce the number of times the needle is inserted into the same portion.

JP 2013-13585 A

  However, the conventional plug body does not have a configuration in which a plurality of mixed injection dimples can be distinguished from each other and is not conspicuous even after the needle is inserted, so the number of times the needle is inserted into the same mixed injection dimple may increase. In this case, there is a high possibility that coring (a phenomenon in which a part (rubber piece) of the plug body is scraped off by the needle) is generated, and there is a concern that the sealing performance is lowered.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a stopper and a medical container that can reduce the number of times the needle is inserted into the same mixed dimple.

In order to achieve the above object, the present invention is a plug made of an elastic material that is disposed in the mouth portion of a medical container and seals the mouth portion, and a plurality of dimples for mixed injection that are pierced during mixed injection, A mixed injection notation unit having a plurality of characters of the same number as the mixed injection dimples and representing a word suggesting mixed injection, which is an operation of injecting a medicine into the medical container with the plurality of characters, and the plurality of mixed injections The dimples are provided so as to be distinguishable from each other, and are provided with discharge dimples that are pierced when the infusion line is connected.In the vicinity of each of the mixed injection dimples, the plurality of characters are assigned one by one. The interval is at least twice the interval between each mixed injection dimple and each character, and at least 1.5 times the height of each character, suggesting discharge in the vicinity of the discharge dimple. That represents the word Indicating section is provided, each of said plurality of characters, on the surface of the plug body, a convex shape protruding from the surface in the thickness direction of the plug body, or the thickness of the plug body relative to the surface It is formed as a groove recessed in the vertical direction .

  According to the plug configured as described above, each character constituting the mixed injection notation portion is assigned in the vicinity of each mixed injection dimple. For this reason, when a needle is inserted into a stopper many times in order to mix and inject a plurality of types of medicines into the contents of a medical container, each needle is used as a mark so that each needle is associated with each mixed dimple. Can be leveled. Accordingly, it is possible to prevent a specific mixed injection dimple from being pierced more times than the other mixed injection dimples, and as a result, the number of times the needle is pierced per one mixed injection dimple can be reduced. Therefore, generation | occurrence | production of a coring and the fall of sealing performance can be suppressed.

  In the plug body described above, a distance between each of the mixed injection dimples and each character may be not more than half of the height of each character. This makes it easier for the characters to appear closer to the mixed injection dimples.

  In the plug, the interval between the plurality of characters may be equal to or greater than the diameter of each of the mixed injection dimples. Thereby, it becomes easy to see the space | interval of a character large.

  In the plug body, the mixed injection notation unit is a word composed of the two characters, and the two characters are arranged outside a circle passing through the centers of the two mixed injection dimples. With respect to the separation direction of the two mixed injection dimples, the characters and the mixed dimples may overlap each other with a length of 20% or more of the diameter of each mixed injection dimple. By arranging each character in this way, it becomes easier for each character to appear as if it is closer to each mixed dimple.

  Next, the configuration of the plug body 10A will be described in more detail. As shown in FIGS. 3 and 4, the surface of the plug body 10 </ b> A (specifically, the surface 27 of the piercing portion 26) has a plurality of mixed dimples 46 to be pierced during mixed injection (see FIG. 5), A discharge dimple 48 that is pierced when the infusion line 72 is connected (see FIG. 6) is provided.

  The plurality of mixed dimples 46 are separated from each other, and in this embodiment, two mixed dimples 46 are provided. When performing mixed injection, the needle 70 (see FIG. 5) of the syringe 68 filled with the medicine is inserted into the mixed dimple 46. Each of the mixed dimples 46 has a circular recess 50 that is recessed in the thickness direction of the plug body 10A, and a circular frame 51 that surrounds the recess 50 and protrudes in the thickness direction of the plug body 10A. In this embodiment, the recessed part 50 is formed in the substantially column shape, and has the flat bottom part 50a.

  In the plug body 10A, only one discharge dimple 48 is provided. When performing the infusion, a bottle needle 76 (see FIG. 6) provided at the end of the infusion line 72 is pierced by the discharge dimple 48. The discharge dimple 48 includes a circular recess 52 that is recessed in the thickness direction of the plug 10A, and a circular frame 53 that surrounds the recess 52 and protrudes from the surface 27 in the thickness direction of the plug 10A. In this embodiment, the recessed part 52 is formed in the column shape, and has the flat bottom part 52a. The thickness of the frame portion 53 of the discharge dimple 48 (line width of the frame portion 53) is formed to be larger than the thickness of the frame portion 51 of the mixed injection dimple 46, whereby the mixed dimple 46 and the discharge dimple 48 is improved.

  Further, on the surface of the plug 10A, it is arranged in the vicinity of the mixed injection dimple 46, and is arranged in the vicinity of the mixed injection notation portion 60 representing the word indicating "mixed injection" and the discharge dimple 48, and suggests "discharge". And a discharge notation section 62 representing a word to be played.

  The mixed injection notation unit 60 includes the same number of characters 61 as the mixed injection dimple 46. In the present embodiment, since two mixed dimples 46 are provided, two characters 61 constituting the mixed injection notation unit 60 are also provided. Specifically, the two characters 61 (61a, 62b) constituting the mixed injection notation unit 60 are “I” and “N”. Therefore, the mixed injection notation unit 60 can read the English word “IN”. Each character 61 constituting the mixed injection notation 60 in the illustrated example has a convex shape protruding from the surface 27 in the thickness direction of the plug 10A. Each character 61 may be a groove that is recessed with respect to the surface 27 in the thickness direction of the plug body 10A.

  Each character 61 constituting the mixed injection notation 60 is assigned to each mixed dimple 46 so that the mixed dimples 46 can be distinguished from each other. That is, in this embodiment in which two mixed injection dimples 46 are provided, one character 61a is arranged in the vicinity of one mixed injection dimple 46a, and the other character 61b is arranged in the vicinity of the other mixed injection dimple 46b. The distance L1 between the characters 61a and 61b is larger than the distance L2 between each mixed dimple 46 and each character 61. Here, the interval L1 is the shortest distance between adjacent characters 61 in the mixed injection notation 60, and the interval L2 is the outer periphery of the corresponding mixed injection dimple 46 (in the illustrated example, the outer peripheral surface of the frame 51) and the character 61. Is the shortest distance.

  In order for each character 61 to be a mark for identifying the mixed injection dimple 46, the interval L1 between each character 61 is preferably as large as possible, and the interval L2 between each mixed injection dimple 46 and each character 61 is preferably as small as possible. . Accordingly, the interval L1 between the characters 61 is set to be twice or more the interval L2 between each mixed dimple 46 and each character 61, and is set to be 1.5 times or more the height L3 of each character 61. Here, the height L3 of the character 61 is a dimension from the upper end to the lower end of the character 61 when the character 61 is viewed in a normal direction.

  Further, the interval L1 between the characters 61 is preferably set to 3 times or more, and more preferably set to 4 times or more, the interval L2 between each mixed dimple 46 and each character 61. By setting the relationship between the interval L1 and the interval L2 as described above, it becomes easier for the character 61 to appear as being closer to the mixed dimple 46.

  Moreover, it is preferable that the space | interval L1 of the character 61 is set to 1.8 times or more of the height L3 of each character 61. FIG. By setting as described above, the interval L1 between the characters 61 can be easily seen.

  Further, the distance L2 between each mixed dimple 46 and each character 61 is preferably set to be equal to or less than half of the height L3 of each character 61, and is set to be one third or less of the height L3 of each character 61. More preferably. By setting as described above, it becomes easier for the character 61 to appear as if it is closer to the mixed injection dimple 46.

  As shown in FIG. 3, each character 61 constituting the mixed injection notation unit 60 is preferably arranged in the vicinity of the outer peripheral portion of the piercing unit 26. Specifically, each character 61 constituting the mixed injection notation unit 60 is disposed on the radially outer side of the plug body 10 </ b> A with respect to a straight line A passing through each center O of the mixed injection dimple 46. Further, each character 61 constituting the mixed injection notation unit 60 is arranged outside a circle B passing through each center O of the two mixed injection dimples 46. As described above, the characters 61 constituting the mixed injection notation unit 60 are arranged in the vicinity of the outer peripheral portion of the piercing unit 26, so that the interval L1 between the characters 61 can be easily increased.

  In the plug body 10A according to the present embodiment, the direction (height direction) of each character 61 constituting the mixed injection notation unit 60 is not perpendicular to the straight line A so that each character 61 is inclined toward the mixed injection dimple 46 side. Further, it is inclined with respect to the straight line A. For this reason, the area between each character 61 and each mixed dimple 46 is small, and each character 61 tends to appear closer to each mixed dimple 46.

  The interval L1 between the characters 61 may be set to be equal to or greater than the diameter D of each mixed injection dimple 46 (in the example shown, the diameter of the outer peripheral portion of the frame 51). Thereby, the space | interval L1 of the character 61 becomes large easily.

  With respect to the separating direction of the two mixed injection dimples 46 (X direction in FIG. 3), each character 61 constituting each mixed injection notation 60 and each mixed dimple 46 is 20% or more of the diameter D of each mixed injection dimple 46. Each character 61 is preferably arranged so as to overlap with each other. By arranging each character 61 in this way, each character 61 is likely to appear as being closer to each mixed dimple 46.

  In the present embodiment, the discharge notation portion 62 is disposed on the radially outer side of the plug body 10 </ b> A with respect to the discharge dimple 48. The characters 63 constituting the discharge notation portion 62 are “O”, “U”, and “T”. Therefore, the discharge notation unit 62 can read the English word “OUT”. Each character 63 constituting the discharge notation portion 62 in the illustrated example has a convex shape protruding from the surface 27 in the thickness direction of the plug body 10A. Each character may have a groove shape that is recessed with respect to the surface 27 in the thickness direction of the plug body 10A.

  On the surface 27 of the plug body 10A, a wall 66 protruding from the surface 27 in the thickness direction of the plug body 10A is provided between the plurality of mixed dimples 46 and the discharge dimple 48. The wall 66 extends continuously between the plurality of mixed dimples 46 and the discharge dimple 48 and is bent in a convex shape having a vertex on the side of the plurality of mixed dimples 46. The wall portion 66 functions as a barrier for preventing a crack when the bottle needle 76 of the infusion line 72 is inserted into the discharge dimple 48 from reaching the mixed dimple 46.

  The language used for the mixed injection notation unit 60 and the discharge notation unit 62 may be a language other than English. That is, each word representing the mixed injection notation unit 60 and the discharge notation unit 62 may be a word other than English words. Therefore, each character 61, 63 may be a character other than the alphabet.

  The stopper 10A and the medical container 12 according to the present embodiment are basically configured as described above, and the operation and effect thereof will be described below. Here, a case will be described in which a larger number of types of drugs than the number of the mixed injection dimples 46 are mixed and injected into the liquid 11 in the medical container 12.

  First, the film 24 is peeled off from the cap 22 of the mouth portion 16 to expose the surface 27 of the plug 10A.

  Next, an operation (mixed injection) for injecting a plurality of types of drugs into the medical container 12 is performed. Specifically, as shown in FIG. 5, a needle 70 of a syringe 68 filled with a medicine is inserted into the stopper 10A. At this time, using one character 61a (see FIG. 3) constituting the mixed injection notation unit 60 as a mark, the needle 70 is inserted into one of the mixed injection dimples 46a, and a pusher (not shown) of the syringe 68 is pressed to medically treat the medicine. Inject into the container 12. When the needle 70 is extracted from the plug 10A after the injection of the medicine, the portion through which the needle 70 has passed is self-closed by the elasticity of the plug 10A itself, so that the liquid in the medical container 12 does not leak. In addition, as a chemical | medical agent mixed infusion, a vitamin agent, an antibiotic agent, an anticancer agent etc. are mentioned, for example.

  Next, using the other letter 61b (see FIG. 3) as a mark, the other mixed injection dimple 46b is pierced with a needle 70 of another syringe 68 filled with another medicine, and the medicine is placed in the medical container 12. After injection, the needle 70 is extracted from the plug 10A. Thus, since the user can identify the mixed injection dimple 46 to which the different character 61 is assigned, when the current needle 70 is inserted, the mixed injection dimple 46 is different from the mixed injection dimple 46 inserted with the previous needle 70. The dimple 46 can be easily selected and the needle 70 can be inserted. Accordingly, when injecting the third and subsequent types of drugs, similarly to the above, the needle 70 can be inserted into the mixed dimple 46 different from the previous one using the character 61 as a mark.

  By mixing the necessary types of drugs, a drug solution having a desired component and concentration can be obtained.

  Next, as shown in FIG. 6, the infusion line 72 is connected to the medical container 12 to discharge the drug solution (infusion solution). Specifically, the bottle needle 76 provided at the end of the infusion line 72 (end of the infusion tube 74) is pierced through the discharge dimple 48 and penetrates the plug 10A. As described above, since the wall portion 66 (see FIGS. 3 and 4) is provided between the plurality of mixed dimples 46 and the discharge dimple 48 on the surface 27 of the stopper 10A, the bottle needle 76 is provided. It is prevented that the crack reaches the mixed dimple 46 when stabbed. When the bottle needle 76 passes through the stopper 10A, the lumen of the infusion line 72 and the inside of the bag 14 communicate with each other. The liquid medicine is discharged from the bag 14 and supplied to the patient via the infusion line 72.

  As described above, according to the stopper 10A and the medical container 12 according to the present embodiment, each character 61 constituting the mixed injection notation unit 60 is assigned in the vicinity of each mixed injection dimple 46. For this reason, when the needle 70 is pierced many times into the stopper 10A in order to mix and inject a plurality of types of drugs into the contents of the medical container 12, each dimple 61 is used as a mark. The number of times the needle 70 is stabbed with respect to 46 can be leveled. Accordingly, it is possible to prevent only one specific mixed injection dimple 46 from being pierced more times than the other mixed injection dimples 46, and as a result, the number of times the needle 70 per one mixed injection dimple 46 is pierced. Can be reduced. Therefore, generation | occurrence | production of a coring and the fall of sealing performance can be suppressed.

  In the medical container 12 described above, instead of the plug body 10A according to the first embodiment, plug bodies 10B to 10E according to the second to fifth embodiments shown in FIGS. 7 to 10 may be employed. In the second to fifth embodiments, elements having the same or similar functions and effects as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
