  However, in the configuration of Patent Document 1, since the plate clamp must be slid with the tube held down, there is a possibility that the tube breaks during sliding and the liquid remaining in the tube scatters. Further, the slide direction of the plate clamp becomes unstable, and there is a possibility that the tube cannot be reliably moved from the wide part to the narrow part.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a medical instrument that suppresses the scattering of liquid flowing out from the opening end of the tube and stabilizes the sliding direction of the plate clamp. It is in.

  (1) A medical device according to the present invention includes a tube having an open end, a wide portion wider than the outer diameter size of the tube, and a through-hole in which a narrow portion narrower than the outer diameter size of the tube is continuous along the longitudinal direction. A curved plate clamp that is curved along the longitudinal direction, and a holding member that holds the tube and the plate clamp in a direction crossing each other. The holding member holds the plate clamp so as to be slidable between a pair of curved walls that are curved along the curved shape of the plate clamp and are opposed to each other. And a tube through-hole through which the tube inserted through the through-hole is inserted. The plate clamp has a grip portion, and slides along the holding member when the grip portion is moved.

  According to the said structure, since the slide to the sliding direction of a plate clamp is guided by a pair of curved wall, the movement of the tube between a wide part and a narrow part can be performed reliably. Further, by operating the gripping portion while the tube is held by the holding member, it is possible to suppress the scattering of the liquid at the time of clamping without holding the tube by hand. Further, by making the plate clamp slidable along the curved sliding direction, it is possible to realize space saving in the sliding direction as compared with the case of sliding linearly.

  (2) Preferably, the holding member is formed with a groove extending in the sliding direction. The grip portion is exposed to the outside of the holding member through the groove.

  According to the said structure, the user can move a tube between a wide part and a narrow part by sliding a holding part in a sliding direction along a groove | channel.

  (3) Preferably, the holding member is provided at a position adjacent to the groove on one end side in the sliding direction, and is overcome by the holding portion of the plate clamp holding the tube in the wide portion. And a second projection that is provided at a position adjacent to the groove on the other end side in the sliding direction and can be overcome by the gripping portion of the plate clamp that holds the tube in the narrow portion. And a protrusion.

  According to the said structure, the movement of the tube between a wide part and a narrow part can be performed reliably by sliding a plate clamp until a holding part gets over a 1st protrusion and a 2nd protrusion. Further, the movement of the tube can be recognized by the user by the resistance when the gripping portion gets over the first protrusion and the second protrusion.

  (4) Preferably, the holding member has a cylindrical portion that protrudes from the tube through hole in the direction of the tube and holds the tube.

  According to the above configuration, since the tube is more stably held by the cylindrical portion, it is possible to more effectively suppress the liquid from splashing due to the open end side of the tube being violated.

  According to the present invention, since the slide of the plate clamp in the sliding direction is guided by the pair of curved walls, the tube can be reliably moved between the wide portion and the narrow portion. Further, by operating the gripping portion while the tube is held by the holding member, it is possible to suppress the scattering of the liquid at the time of clamping without holding the tube by hand. Further, by making the plate clamp slidable along the curved sliding direction, it is possible to realize space saving in the sliding direction as compared with the case of sliding linearly.

  As shown in FIGS. 2 and 3, the first tubular portion 24 extends along the extending direction of the urination tube 15 (that is, the front-rear direction 8). As shown in FIG. 4, the first tubular portion 24 penetrates the front wall 30 and the rear wall 31 at a position surrounding the openings 36 and 37, and holds the urination tube 15 therein. More specifically, the first tubular portion 24 is configured by a portion protruding forward from a position surrounding the opening 36 and a portion protruding backward from a position surrounding the opening 37. Moreover, the guide part 23 and the 1st cylindrical part 24 mutually cross | intersect. More specifically, the tangential direction at the positions of the openings 36 and 37 on the front wall 30 and the rear wall and the axial direction of the first cylindrical portion 24 intersect each other (in the example of FIG. 4, they are orthogonal). In other words, the tangential direction at the positions of the openings 36 and 37 of the plate clamp 22 held by the guide portion 23 and the axial direction of the urination tube 15 held by the first tubular portion 24 intersect each other (FIG. 4). In the example of FIG.

  The inner diameter dimension of the first cylindrical portion 24 is set slightly larger than the outer diameter dimension of the urination tube 15 and is substantially constant in the front-rear direction 8. A second cylindrical part 25 is provided at the front end (front end in the front-rear direction 8) of the first cylindrical part 24, and the rear end (rear end in the front-rear direction 8) is open.

A flange portion 26 is formed that extends radially outward from the surface.

  As shown in FIGS. 2 and 3, the second cylindrical portion 25 is provided at the tip of the first cylindrical portion 24 (the end portion on the front side in the front-rear direction 8). More specifically, as shown in FIG. 4, one end portion of the second cylindrical portion 25 extends inside the first cylindrical portion 24, and passes through the opening end 17 to the urine tube 15. Has been inserted. That is, the outer diameter dimension of the second cylindrical portion 25 is set to be the same as the inner diameter dimension of the urination tube 15 or slightly larger than the inner diameter dimension of the urination tube 15. On the other hand, the other end portion of the second cylindrical portion 25 extends in a direction away from the first cylindrical portion 24 and is opened to the outside.

  The internal spaces of the first cylindrical portion 24 and the second cylindrical portion 25 are in communication as shown in FIG. The urination tube 15 is inserted into the first tubular portion 24 and the second tubular portion 25 is fitted into the open end 17. That is, the urination tube 15 inserted into the first cylindrical portion 24 communicates with the outside through the second cylindrical portion 25.

  As shown in FIG. 5A, the plate clamp 22 is a plate-like member curved along the longitudinal direction (slide direction 6). The plate clamp 22 is curved along the curved shape of the front wall 30 and the rear wall 31 of the guide portion 23. In other words, the front wall 30 and the rear wall 31 of the guide portion 23 are curved along the curved shape of the plate clamp 22, that is, the front wall 30 and the rear wall 31 of the guide portion 23 and the plate clamp 22 are Curved with approximately the same curvature.

  The plate clamp 22 is formed with a through hole 27 that penetrates in the thickness direction. As shown in FIG. 5B, the through hole 27 includes a wide portion 27A and a narrow portion 27B. The wide portion 27A has a wider opening width in the left-right direction 9 than the narrow portion 27B. More specifically, the opening width of the wide portion 27 </ b> A in the left-right direction 9 is wider than the outer diameter size of the urination tube 15. On the other hand, the width of the narrow portion 27B in the left-right direction 9 is narrower than that of the wide portion 27A. More specifically, the opening width of the narrow portion 27 </ b> B in the left-right direction 9 is slightly narrower than twice the wall thickness of the urination tube 15. Further, the wide portion 27A and the narrow portion 27B are continuous along the longitudinal direction of the plate clamp 22 (that is, the slide direction 6).

  Further, as shown in FIG. 5A, the plate clamp 22 is provided with a grip portion 28 that protrudes from one surface in the thickness direction (surface on the curved outer side). More specifically, the grip portion 28 is provided at the end portion on the side where the wide portion 27 </ b> A is formed in the longitudinal direction of the plate clamp 22. The grip portion 28 includes a base portion 28A protruding from the plate clamp 22 and a handle 28B provided at the tip of the base portion 28A. The width of the base portion 28 </ b> A in the left-right direction 9 is narrower than the opening width in the left-right direction 9 of the groove 33 provided in the front wall 30. On the other hand, the width of the handle 28 </ b> B in the left-right direction 9 is wider than the opening width of the groove 33 in the left-right direction 9.

  The plate clamp 22 having the above configuration is inserted into the internal space of the guide portion 23 through one end portion of the guide portion 23 opened with the end portion on the narrow portion 27B side in the longitudinal direction as a tip. At this time, the base portion 28 </ b> A of the grip portion 28 is fitted into the groove 33 and the handle 28 </ b> B is exposed from the guide portion 23. Further, the urination tube 15 is inserted into the first cylindrical portion 24 of the holding member 21 in which the plate clamp 22 is inserted. As a result, as shown in FIG. 4, the urination tube 15 extending in the front-rear direction 8 is inserted through the through hole 27 of the plate clamp 22 held by the guide portion 23 with the longitudinal direction facing the slide direction 6.

  The plate clamp 22 is guided by the inner wall surface that defines the internal space of the guide portion 23 and can slide in the sliding direction 6. More specifically, as shown in FIGS. 2 (A) and 3 (A), the plate clamp 22 has a position where the handle 28B has passed over the first protrusion 34 toward the closed end 33A, and FIG. 2 (B). As shown in FIG. 3B, the handle 28B is slidable between a position where the handle 28B gets over the second protrusion 35 toward the open end 33B. At this time, by sliding against the inner wall surfaces of the front wall 30, the rear wall 31, and the left wall 32, the slide of the plate clamp 22 in the sliding direction 6 is guided.

  The plate clamp 22 is disposed at the position shown in FIGS. 2 (A), 3 (A), and 4 (A) (that is, the position where the handle 28B gets over the first protrusion 34 toward the closed end 33A). When opening, the openings 36 and 37 of the guide portion 23 and the wide portion 27A of the through hole 27 of the plate clamp 22 are aligned in a substantially straight line in the front-rear direction 8. As a result, the urination tube 15 held by the holding member 21 is inserted through the through hole 27 of the plate clamp 22 at the position of the wide portion 27A, as shown in FIG. Since the opening width of the wide portion 27A is wider than the outer diameter size of the urination tube 15, the clamp device 20 in this state (hereinafter referred to as “allowable state”) allows the urine flow in the urine tube 15 to be allowed. doing.

  On the other hand, the plate clamp 22 is disposed at the position shown in FIGS. 2B, 3B, and 4B (that is, the position where the handle 28B gets over the second protrusion 35 toward the open end 33B). In this case, the openings 36 and 37 of the guide portion 23 and the narrow portion 27B of the through hole 27 of the plate clamp 22 are aligned in a substantially straight line in the front-rear direction 8. As a result, the urination tube 15 held by the holding member 21 is inserted into the through hole 27 of the plate clamp 22 at the position of the narrow portion 27B, as shown in FIG. 6B. Since the opening width of the narrow portion 27B is narrower than twice the wall thickness of the urination tube 15, the urination tube 15 is crushed by the narrow portion 27B. That is, the clamp device 20 in this state (hereinafter referred to as “restricted state”) restricts the flow of urine in the urine tube 15.

[Operational effects of this embodiment]
The clamping device 20 in the present embodiment is switched between an allowable state and a restricted state, for example, by being operated as follows. First, with respect to the clamp device 20 in the allowable state shown in FIGS. 2 (A) and 3 (A), the user who puts his finger on the handle 28B moves toward the open end 33B side of the groove 33 along the slide direction 6. Slide the plate clamp 22. Then, by sliding the plate clamp 22 until the handle 28B gets over the second protrusion 35 to the open end 33B side (that is, to the position shown in FIGS. 2B and 3B), the clamping device 20 is moved. Switch from allowed state to restricted state.

  Here, the plate clamp 22 slid to the open end 33 </ b> B side is restricted from tilting in the front-rear direction 8 by abutting against the inner wall surfaces of the front wall 30 and the rear wall 31, and abuts against the inner wall surface of the left wall 32. As a result, the inclination in the left-right direction 9 is restricted. That is, in the process in which the plate clamp 22 is slid, the guide portion 23 varies in the intersection angle (90 ° in the present embodiment) between the tangential direction of the plate clamp 22 and the urination tube 15 at the positions of the openings 36 and 37. Can be regulated. Thereby, the urination tube 15 can be reliably moved from the wide part 27A to the narrow part 27B. Note that the angle of intersection between the tangential direction of the plate clamp 22 and the urination tube 15 at the positions of the openings 36 and 37 is not limited to 90 °, but is preferably close to 90 °.

  Moreover, according to this embodiment, the one end of the 2nd cylindrical part 25 is inserted in the opening end 17 side of the urination tube 15, and the opening end 17 is not directly exposed outside. Accordingly, it is possible to prevent the urine from being scattered due to the open end 17 side of the urination tube 15 being unfolded when being pushed into the narrow portion 27B. However, the second cylindrical portion 25 is not an essential component of the present invention and can be omitted.

  Further, according to the present embodiment, by allowing the plate clamp 22 to slide along the curved slide direction 6, the clamp device 20 in the slide direction 6 is compared with the case of sliding the plate clamp 22 linearly. The space saving can be realized.

  Further, according to the present embodiment, by providing the flange portion 26 in the first tubular portion 24, the first urine that flows down from the tip of the second tubular portion 25 along the outer peripheral surface in the state of FIG. It can suppress that the cylindrical part 24 is contaminated. As a result, the clamp device 20 can be operated in a sanitary manner.

  Further, according to the present embodiment, the first protrusion 34 and the second protrusion 35 are provided at a position adjacent to the groove 33, and the user can slide the plate clamp 22 until the handle 28B gets over these, thereby allowing the allowable state and the restriction. The state can be switched reliably, and the user can be made aware that the state has been switched.

  In addition, the holding member 21 in the above embodiment is molded from a hard resin having non-flexible hardness. By doing in this way, the user can hold the holding member 21 with peace of mind, and can press the plate clamp 22 strongly while holding the holding member 21. Furthermore, since the urination tube 15 can be stably held, the splash of liquid from the tip of the urination tube 15 can be suitably suppressed. However, the subject of the present invention (the guide of the plate clamp 22 and the suppression of the splash of liquid from the tip of the urine tube 15) is not limited to the material of the holding member 21, and the opening end 17 side of the urine tube 15 is held by the holding member 21. If so, it can be solved. Therefore, the material constituting the holding member 21 is preferably a non-flexible hard resin, but may be a soft resin or may be flexible.

  Moreover, although this embodiment demonstrated the urine bag 10 which stores urine as an example of a medical device, this invention is not limited to this. In other words, the present invention can be applied to any medical instrument including a drain tube that discharges liquid (typically body fluid) and a clamp device 20 that allows or regulates the flow of the liquid in the drain tube. .

  Further, in this embodiment, the groove 33 is formed in the front wall 30 which is one of the pair of curved walls. However, the groove may be formed in the left wall 32, or the grip portion 28 may be formed from the opened right side surface. May be exposed to the outside. Further, as in the present embodiment, the grip portion 28 does not have to be a protrusion protruding from the plate clamp 22. For example, if the holding member 21 is provided with a notch large enough to hold the plate clamp 22, the end of the plate clamp 22 exposed from the notch becomes the holding part.
