When the two-joint member 27 rotates about the third joint portion 30, the arm main body portion 25 rotates up and down the headrest 6 (see FIGS. 14 and 15). Therefore, the arrangement of the shield main body 41 with respect to the practitioner can be freely changed up and down, and the shield main body 41 is arranged at a position that does not interfere with the treatment and can block dust and the like. ..

In the present embodiment, the shield 12 has a fourth joint portion 31 connecting the second joint member 27 and the support portion 21, and since the fourth joint portion 31 has an axis in the left-right direction, the first joint When the member 26 rotates about the fourth joint portion 31 as an axis, the arm main body portion 25 retracts from the front side of the headrest 6 and rotates toward the crown side, and the direction of the shield main body portion deviates from the front side (FIG. 18 and FIG. 19). Therefore, when the person to be treated P gets up, the shield main body 41 does not interfere with the person to be treated P.

In the present embodiment, the first joint member 26 has a fourth joint portion 31 and a regulation operation unit 33 that regulates the operation by the fourth joint portion 31 (see FIG. 8). The regulation operation unit 33 has an operation body unit 34 and a locking hole 36 to which the operation body unit 34 is locked, and the operation shaft portion 45 of the operation body unit 34 is inserted into the locking hole 36. Therefore, the movement by the fourth joint portion 31 is restricted. Since the arm body 25 is restricted from rotating toward the back side of the headrest 6 by the regulation operation unit 33, if the practitioner places the legs on the back side of the headrest 6. Even if there is, the arm body 25 does not interfere with the practitioner's legs.

In the present embodiment, the shield 12 has a fifth joint portion 32 connecting the support portion 21 and the headrest 6. Since the fifth joint portion 32 has the front direction and the back direction as axes, when the support portion 21 rotates about the fifth joint portion 32, the arm portion 20 rotates around the headrest 6. That is, the arm portion 20 is arranged on the right side, the crown side, or the left side of the headrest 6. Therefore, the practitioner can perform the treatment on the treated person P from either the left or right side or the crown.

In the present embodiment, the support portion 21 has a long plate shape, the right end of the support portion 21 is connected to the back surface portion of the headrest 6, and the left end of the support portion 21 is the first joint member 26 and the second joint member. It is connected to the arm main body 25 via 27. That is, the arm main body 25 is separated from the headrest 6 by the support portion 21, and the arm main body 25 and the headrest 6 are separated to the extent that the practitioner's arm can pass through (see FIG. 15). Therefore, when the practitioner performs the treatment from the crown side of the treated person P, the practitioner can place the arm on the side of the face of the treated person P, and the arm body portion 25 does not interfere with the arm.

In the present embodiment, the shield main body 41 has a quadrangular shape in which the first corner 42 and the second corner 43 are cut, respectively. The first corner 42 is on the right side opposite to the support portion 21 with respect to the headrest 6 and on the upper side on the crown side of the headrest 6 (see FIG. 17). Therefore, the practitioner can perform the treatment by bringing the body closer to the shield main body 41 from the vicinity of the upper right of the practitioner P, which is the position where the practitioner generally sits.

In the present embodiment, the shield 12 has a second shield main body 44 attached to the outside of the arm main body 25 (see FIGS. 11 to 13). With this configuration, the second shield main body 44 is arranged between the practitioner and the practitioner P on the left side of the arm main body 25. Therefore, for example, the shield main body 41 separates the dentist from the treated person P, and the second shield main body 44 separates the dental hygienist from the treated person P.

In the present embodiment, the dental clinic device 1 has a shield control unit that regulates a predetermined operation of the dental clinic chair 2 according to the posture of the sanitary shield 12 for the dental clinic chair. The shield control unit receives signals according to the states of the joint portions 28, 29, 30, 31, 32 from the sensors attached to the joint portions 28, 29, 30, 31, 32. The shield control unit regulates a predetermined operation of the backrest 5 when the arm main body 25 is in a position extending toward the front side of the headrest 6 (see FIGS. 14 and 15). Here, the predetermined operation is arbitrary and preset. The predetermined operation includes, for example, an operation in which the backrest 5 exceeds a predetermined angle, and the operation of finely adjusting the posture of the backrest 5 is excluded. The person to be treated P may get up with the movement of the backrest 5, but when the shield main body 41 is on the front side of the headrest 6, the backrest 5 is restricted from the predetermined movement and therefore is subject to the treatment. The practitioner P is not hung up and does not get up, and the practitioner P is prevented from hitting the shield main body 41. Further, since the backrest 5 does not operate, the shield main body 41 does not interfere with peripheral devices.

In the present embodiment, the auxiliary light 51 that illuminates the mouth of the person to be treated P is arranged between the shield main body 41 and the mouth of the person to be treated P. That is, there is no shield main body 41 between the auxiliary light 51 and the mouth of the person to be treated P, and there is no shadow. Therefore, the mouth is directly illuminated by the light of the auxiliary light 51. Further, since the auxiliary light 51 is supported by the flexible hose 59 for the light, it can move freely and stands still at an arbitrary position. Therefore, the practitioner can point the auxiliary light 51 at any position that does not interfere with the treatment, and can move the auxiliary light 51 to any position that does not hit the auxiliary light 51 when the person to be treated gets up.

In the present embodiment, the suction nozzle 14 is supported by a flexible hose for the suction nozzle and is arranged between the shield main body 41 and the mouth of the person to be treated P. The flexible hose for the suction nozzle is attached to the headrest 6, the arm portion 20, or the shield main body portion 41. That is, the suction nozzle 14 can move freely and stands still at an arbitrary position. Therefore, the practitioner can point the suction nozzle 14 at an arbitrary position that does not interfere with the treatment, and can move the suction nozzle 14 to an arbitrary position that does not hit the suction nozzle 14 when the person to be treated P gets up. Further, the shield main body 41 does not exist between the suction nozzle 14 and the mouth of the person to be treated P, and there is no obstacle. Therefore, the practitioner can perform an appropriate treatment. Further, since the suction nozzle 14 sucks dust and the like, the shield main body 41 is not contaminated by the dust and the like.

Next, the dental vacuum 13 according to the embodiment of the present disclosure and the suction nozzle 14 of the dental vacuum 13 will be described with reference to the drawings. 20 and 21 show the appearance of the suction nozzle 14. FIG. 22 shows the usage state of the suction nozzle 14.

As shown in FIGS. 14 to 19, the dental vacuum 13 has a suction nozzle 14 arranged outside the oral cavity of the person to be treated P in the dental treatment. The dental vacuum 13 is arranged between the hose 50 connected to the cuspider unit 8, the suction nozzle 14 connected to the hose 50, and the suction nozzle 14 and the mouth of the person to be treated P. It has an auxiliary light 51 that illuminates the mouth of the practitioner P, and a vacuum control unit (not shown) that performs various controls according to the position of the suction nozzle 14. The auxiliary light 51 is supported by the flexible hose 59 for light and can move freely, and is directed to an arbitrary position. The vacuum control unit has a suction control unit that controls suction according to the posture of the suction nozzle 14, and a chair control unit that regulates a predetermined operation of the dental clinic chair 2. The device on which the vacuum control unit is mounted is arbitrary. Therefore, the vacuum control unit is mounted on, for example, a dental clinic chair 2, a cuspider unit 8, and other peripheral devices.

The hose 50 is on the left side of the dental clinic chair 2, and is connected to the headrest 6 or the backrest 5 or supported by a self-supporting support arm (not shown). Since the support arm extends from the back surface of the dental clinic chair 2 toward the front side and can move freely, the support arm is to the right, which is the direction toward the dental clinic chair 2, or to the left, which is the direction away from the dental clinic chair 2. Is also mobile. Therefore, the suction nozzle 14 is arranged at an arbitrary position such as the side or the back side of the headrest 6 or the backrest 5 as the support arm moves. A sensor (not shown) is attached to the suction nozzle 14 or the hose 50. The sensor outputs a signal corresponding to the posture of the suction nozzle 14 to the vacuum control unit.

As shown in FIGS. 20 and 21, the suction nozzle 14 is bottle-shaped and transparent or translucent. The suction nozzle 14 has a hollow cylindrical nozzle body 52, a connection port 53 formed in the nozzle body 52 and connected to the hose 50, and a bottom portion 54 facing the connection port 53. The nozzle body 52 has a suction port 55 formed on a side surface thereof, and the nozzle body 52 has a receiving portion 56 connected under the suction port 55.

The connection port 53 has a shape corresponding to the diameter of the hose 50, and the diameter of the nozzle body 52 is formed to be larger than the diameter of the connection port 53. Therefore, between the nozzle main body 52 and the connection port 53, a diameter-expanded portion 57 is formed in which the diameter of the nozzle main body 52 is gradually increased. The connection port 53 can be attached to and detached from the hose 50.

The suction port 55 is an elongated hole or an ellipse along the lateral width in the longitudinal direction of the nozzle body 52. The width of the suction port 55 is equal to or larger than the general mouth size of the subject P. The vertical width of the suction port 55 orthogonal to the longitudinal direction is shorter than the diameter of the nozzle body 52. The vertical width of the suction port 55 is, for example, about 3/4 or less of the diameter of the nozzle body 52.

As shown in FIG. 22, the suction nozzle 14 is arranged below the shield main body 41 and at the mouth of the person to be treated P in a posture similar to a state in which the bottle is laid down sideways. In this posture, the side facing the mouth of the person to be treated P is the facing surface 58, and the facing surface 58 is the side surface of the nozzle body 52. The facing surface 58 has a suction port 55 formed smaller than the facing surface 58, and the suction port 55 is horizontally long along the mouth of the person to be treated P. The receiving portion 56 is arranged below the suction port 55 on the facing surface 58. The auxiliary light 51 is located at the mouth of the person to be treated P, at a position where the auxiliary light 51 is displaced from the position facing the suction port 55 and does not interfere with suction.

As described above, the suction nozzle 14 is configured.

Next, the action and effect of the suction nozzle 14 will be described.

As described above, in the present embodiment, the suction nozzle 14 is formed on a bottle-shaped nozzle body 52 having a bottom portion 54 and a suction port 55 and a hollow cylindrical shape, and a side surface of the nozzle body portion 52. It has a suction port 55 and a receiving portion 56 connected under the suction port 55 (see FIGS. 20 and 21). With this configuration, even when the water sucked from the suction port 55 adheres to the inner surface of the nozzle body 52 and becomes water droplets, the water droplets collect in the receiving portion 56. Therefore, the suction nozzle 14 can prevent water droplets from dripping.

In the present embodiment, the connection port 53 has a shape corresponding to the diameter of the hose 50, and the diameter of the nozzle body 52 is formed to be larger than the diameter of the connection port 53. Since the size of the suction port 55 depends on the size of the nozzle body 52, if the size of the nozzle body 52 is the same as that of the connection port 53, the size of the suction port 55 is connected. It will depend on the size of the mouth 53. In the present embodiment, since the size of the nozzle main body 52 is larger than that of the connection port 53, the size of the suction port 55 is determined and appropriate without depending on the size of the connection port 53.

In the present embodiment, the suction port 55 is formed smaller than the facing surface 58. Specifically, the suction port 55 has an elongated hole or an elliptical shape along the lateral width in the longitudinal direction of the nozzle body 52, and the vertical width orthogonal to the longitudinal direction is shorter than the diameter of the nozzle body 52 (). See FIGS. 20 and 21). That is, since the vertical width of the suction port 55 is shorter than the diameter of the nozzle body 52, the receiving portion 56 is formed. With this configuration, while having the receiving portion 56, the shape is suitable for sucking at the mouth of the person to be treated P, and the shape is suitable for realizing negative pressure at the suction port 55.

In this embodiment, the connection port 53 can be attached to and detached from the hose 50. Therefore, it can be attached to and detached from the existing vacuum hose for dental practice.

In this embodiment, the suction nozzle 14 is transparent or translucent. Therefore, the practitioner can visually recognize the dust and the like accumulated inside the nozzle main body 52, and can determine whether or not cleaning or replacement is performed.

In the present embodiment, the support arm extends from the vicinity of the headrest 6 or the backrest 5 and stands on its own without being fixed to peripheral devices. Since the water droplets collect in the receiving portion 56, the practitioner does not have to worry about the water droplets dripping, and therefore does not need to support the suction nozzle 14 by hand. Therefore, the suction nozzle 14 can be supported by the support arm to be self-supporting. Further, the practitioner can move the suction nozzle 14 together with the support arm when it is not necessary.

In the present embodiment, the hose 50 is on the left side of the dental clinic chair 2 and is supported by a support arm connected to the headrest 6 or the backrest 5. Since the support arm can be freely moved, it can also be moved to the right, which is the direction toward the dental treatment chair 2, or to the left, which is the direction away from the dental treatment chair 2. Therefore, the suction nozzle 14 is arranged at an arbitrary position such as the side or the back side of the headrest 6 or the backrest 5 as the support arm moves. That is, when the suction nozzle 14 is separated from the mouth of the person to be treated P, the suction nozzle 14 does not interfere with the person to be treated P when the person to be treated P rises up. Further, since the suction nozzle 14 is arranged on the back side of the dental clinic chair 2, when the person to be treated P gets up, the suction nozzle 14 does not interfere with the person to be treated P, and the suction nozzle 14 also interferes with peripheral devices. do not do.

In the present embodiment, there is an auxiliary light 51 that is arranged between the suction nozzle 14 and the mouth of the person to be treated P and illuminates the mouth of the person to be treated P (see FIG. 22). That is, there is no suction nozzle 14 or other device between the auxiliary light 51 and the mouth of the person to be treated P, and there is no shadow. Therefore, the mouth is directly illuminated by the light of the auxiliary light 51. Since the existing dental light of the dental treatment apparatus 1 is arranged above the suction nozzle 14, the suction nozzle 14 may be a shadow.

In the present embodiment, the dental vacuum 13 has a vacuum control unit that performs various controls according to the position of the suction nozzle 14. The vacuum control unit receives a signal according to the posture of the suction nozzle 14 from the sensor attached to the suction nozzle 14 or the hose 50. Among the vacuum control units, the suction control unit stops suction when the suction nozzle 14 is separated from the mouth of the person to be treated P. Therefore, the practitioner does not need to separately operate the movement of the suction nozzle 14 and the stop of suction when it is not necessary, which is convenient. Among the vacuum control units, the chair control unit regulates a predetermined operation of the backrest 5 when the suction nozzle 14 is at the mouth of the person to be treated P. Here, the predetermined operation is optional and preset. The predetermined operation includes, for example, an operation in which the backrest 5 exceeds a predetermined angle, and the operation of finely adjusting the posture of the backrest 5 is excluded. The person to be treated P may get up with the movement of the backrest 5, but when the suction nozzle 14 is at the mouth of the person to be treated P, the backrest 5 is subject to the predetermined movement because the predetermined movement is restricted. The practitioner P is not hung up and does not get up, and the practitioner P is prevented from hitting the suction nozzle 14. Further, since the backrest 5 does not operate, the suction nozzle 14 does not interfere with peripheral devices.
