Description

The present invention relates to a tube joining device used for joining tubes.

As a technique for connecting resin tubes or the like, a joining method has been conventionally known in which the ends of each resin tube are fused and the fused ends are pressed against each other to be pressure-bonded. Such a technique is widely used in various industrial fields, and as an example, an attempt is made to apply it to a medical technique such as a peritoneal dialysis method.

In the peritoneal dialysis method, a tube (catheter) implanted in the abdominal cavity of a patient is used to put a predetermined dialysate into the body, and then water and waste products transferred into the dialysate through the peritoneum are removed from the body. The method. When the dialysate is put into the body, the tube embedded in the patient is tightly joined to the tube of the bag containing the dialysate. Also, when draining dialysate from the body, the tube embedded in the patient is tightly joined to the drainage bag tube.

As described above, one of the tubes to be joined is embedded in the abdominal cavity of the patient, so great care must be taken in the work so that each tube is not contaminated during the joining work. In view of these points, for example, as described in Patent Document 1, a tube joining device capable of fusing two resin tubes and automatically joining them in an aseptic state has been developed. Has been done. In this device, the ends of the two tubes are fused while being covered with a cover, and the ends of the two fused tubes are exchanged and joined. Since the fusing-joining of the two tubes is performed in a state where the fusing-joining site is isolated from the outside, there is no concern about bacterial contamination, and the sterility of the dialysate and the like in the tube and the bag can be maintained.

And have. Hereinafter, the configuration of each part of the tube holding part 23 will be described.

First, the first holding portion 232 and the second holding portion 233 will be described.

The first holding portion 232 is fixed to the side surface of the first pedestal 211. The first holding portion 232 includes a concave first groove portion 232a into which the first tube T1 can be fitted, and a concave second groove portion 232b into which the second tube T2 can be fitted.

As shown in FIG. 9A, the first groove portion 232a and the second groove portion 232b are provided so as to be arranged in a direction inclined by an angle θ with respect to the height direction Z of the housing 10 (diagonal direction D1). .. Therefore, the first tube T1 and the second tube T2 are held by the first holding portion 232 in a state of being juxtaposed in the diagonal direction D1. The first groove portion 232a arranged behind the juxtaposed direction D1 of the first tube T1 and the second tube T2 is arranged at a position higher in the height direction Z of the housing 10 than the second groove portion 232b. ..

Further, the groove portions 232a and 232b are provided so as to be concavely recessed along the direction D2 orthogonal to the oblique direction D1 on the upper surface side of the first holding portion 232. Therefore, the tubes T1 and T2 are set so as to be inserted from the direction D2 orthogonal to the juxtaposed direction D1. Therefore, with the lid portion 22 open, the user M can easily insert and set the tubes T1 and T2.

As shown in FIG. 9B, the second holding portion 233 is rotatably provided on the side surface of the second pedestal 212. The second holding portion 233 is provided with a concave third groove portion 233c into which the replacement side X1 of the first tube T1 can be fitted and a concave fourth groove portion 233d into which the replacement side X1 of the second tube T2 can be fitted. There is.

The second holding portion 233 is a position where the third groove portion 233c and the fourth groove portion 233d are arranged along the diagonal direction D1 and can hold the tubes T1 and T2 together with the first holding portion 232 (referred to as "holding position P0"). And, it is configured to be movable between the position where the holding is released (referred to as "release position P1"). The holding position P0 is the position shown in FIG. 9B, and the release position P1 is the position shown in FIG. 10B.

In the present embodiment, as shown in FIG. 9A, the angle θ formed between the oblique direction D1 and the height direction Z of the housing 10 is 45 degrees. That is, in each holding portion 232 and 233, the virtual line (indicated by the chain line in the figure) connecting the axis of the first tube T1 and the axis of the second tube T2 is 45 degrees with respect to the height direction Z. The first tube T1 and the second tube T2 are held so as to form an angle. The angle θ does not necessarily have to be 45 degrees, and can be, for example, an angle larger than 0 degrees and smaller than 90 degrees.

In this way, the holding portions 232 and 233 individually hold the tubes T1 and T2 in a state of being juxtaposed in the diagonal direction D1 with respect to the height direction Z of the housing 10. As shown in FIG. 9A, since the user M sits on a chair or the like and looks into the tube joining device 1 placed on the table or the like from diagonally above, the user M does not change his / her posture. , Each tube T1 and T2 can be set in each holding portion 232 and 233. Further, the user M can easily visually recognize whether or not each of the set tubes T1 and T2 is properly set (presence or absence of twisting or the like).

Next, the release unit 234 and the restoration unit 235 will be described.

As shown in FIG. 5, the release portion 234 includes a flat surface 234a connected to the side surface of the second clamp arm 222, and a protrusion 234b protruding from the second holding portion 233 toward the flat surface 234a of the second clamp arm 222. It is equipped with.

The protrusion 234b provided on the second holding portion 233 abuts on the flat surface 234a provided on the lid portion 22 as the lid portion 22 moves relatively close to the housing 10. When the lid 22 is further pushed down (relatively close to the housing 10) from the state where the protrusion 234b is in contact with the flat surface 234a, the second holding portion 233 has a lid as shown in FIG. 10 (B). It is pushed down in the direction away from the portion 22 to release the holding of the tubes T1 and T2. As described above, the release portion 234 is configured to retract the second holding portion 233 from the holding position P0 to the release position P1 as the lid portion 22 moves relatively close to the housing 10.

As shown in FIG. 9B, the restoring portion 235 has a cam 235a capable of pushing up the second holding portion 233 in conjunction with the operation in which the second clamp arm 222 of the lid portion 22 is relatively separated from the housing 10. It is equipped with.

The cam 235a has a substantially fan-shaped outer shape when viewed from the side surface of the housing 10. The cam 235a is fixed in the vicinity of the rotating portion of the second clamp arm 222. Therefore, the cam 235a also rotates in conjunction with the rotation of the second clamp arm 222. The curved surface of the cam 235a comes into contact with the bottom surface of the second holding portion 233 in a state where the lid portion 22 is opened to some extent, and keeps the second holding portion 233 at the holding position P0. When the lid portion 22 is relatively close to the housing 10, the curved surface of the cam 235a separates from the second holding portion 233 before the protrusion 234b of the release portion 234 abuts on the flat surface 234a. Therefore, when the lid portion 22 is changed from the open state to the closed state, the cam 235a does not prevent the second holding portion 233 from moving from the holding position P0 to the release position P1 by the release portion 234. On the other hand, when the lid portion 22 is changed from the closed state to the open state, the cam 235a comes into contact with the second holding portion 233 and pushes up the second holding portion 233. As a result, the second holding portion 233 returns from the release position P1 to the holding position P0.

As described above, the release unit 234 and the restoration unit 235 allow the second holding unit 233 to be movable between the holding position P0 and the release position P1. Therefore, the position exchange work of exchanging the positions of one side of the first tube T1 and one side of the second tube T2 after fusing, which is performed with the lid portion 22 closed, is not hindered by the second holding portion 233.

Next, the tube detection sensor 24 will be described.

As shown in FIG. 6, the tube detection sensor 24 is provided in the first groove portion 232a and the second groove portion 232b of the first holding portion 232. The tube detection sensor 24 has a function of detecting whether or not the tubes T1 and T2 are set in the groove portions 232a and 232b of the first holding portion 232. Hereinafter, the configuration of the tube detection sensor 24 will be described by taking the tube detection sensor 24 set in the first groove portion 232a as an example.

The tube detection sensor 24 receives the magnetic force of the pin 241 that can protrude from the hole provided in the first groove portion 232a, the base 242 that supports the pin 241 and the magnet 243 attached to the base 242, and the magnet 243. It includes a detectable Hall element 244 and an urging member 245 that imparts an urging force to the pin 241 in a direction protruding from the hole. In the present embodiment, the urging member 245 is configured by a spring, but the configuration of the urging member 245 is not particularly limited as long as the urging force in the direction protruding from the hole can be applied to the pin 241.

In a state where the first tube T1 is not set in the first groove portion 232a, as shown in FIG. 6A, the pin 241 receives the urging force of the urging member 245 while the base 242 receives the first holding portion 232. It abuts on the inner surface of the pin 241 to regulate the operation of the pin 241. Therefore, the tip end side of the pin 241 is in a state of protruding from the hole. In this state, since the magnet 243 is arranged in the vicinity of the Hall element 244, the magnetic force of the magnet 243 that can be detected by the Hall element 244 is strong. On the other hand, as shown in FIG. 6B, when the first tube T1 is arranged in the first groove portion 232a, the pin 241 and the base 242 are placed in the internal space of the first holding portion 232 by the first tube T1. Be pushed in. As a result, the magnet 243 attached to the base 242 is separated from the Hall element 244, so that the magnetic force of the magnet 243 that can be detected by the Hall element 244 is weakened. In this way, the tube detection sensor 24 determines whether or not the first tube T1 is set in the first groove portion 232a and the depth of the first groove portion 232a depending on the strength of the magnetic force of the magnet 243 that can be detected by the Hall element 244. It is possible to detect whether or not 1 tube T1 is pushed.

The tube detection sensor 24 may be provided in the second holding portion 233.

Next, the tube pressing portion 25 will be described.

When the control unit 90 determines in step (S7) that the second tube T2 has not been removed from the housing 10 (step S7; NO), the control unit 90 again performs the operation of step (S6, S7). implement.

When the control unit 90 determines in step (S7) that the second tube T2 has been removed from the housing 10 (step S7; YES), the control unit 90 automatically turns off the power. Notify user M. In this way, the user M can remove the peritoneal side of the second tube T2 from the tube joining device 1 and detach from the tube joining device 1 according to the operation method notified by the notification unit 70.

As shown in FIG. 23, each tube T1 and T2 may be provided with a clamp C capable of clamping each tube T1 and T2 from the outside of the tube joining device 1 as an accessory. The detachment clamp 110 built in the tube joining device 1 clamps the peritoneal side of the second tube T2 to the second tube even if the position exchange operation is stopped in the middle, even if it is not used in combination with the attached clamp C. Aseptic condition on the peritoneal side of T2 can be ensured. Therefore, for example, when the attached clamp C is lost, even if the position exchange operation is stopped in the middle, the aseptic state on the peritoneal side of the second tube T2 can be suitably secured. Further, it is not necessary to combine the clamps C with the generally disposable tubes T1 and T2 for sale, and the cost of using the tubes T1 and T2 can be reduced. The release clamp 110 can also be used in combination with the attached clamp C.

As described above, the tube joining device 1 according to the present embodiment clamps the housing 10 provided with the openable / closable lid portion 22 and one of the first tube T1 and the second tube T2 (second tube T2). A detachment clamp 110 that can block the flow path of one tube and can be removed from the housing 10 with one tube clamped, and a detachment clamp 110 with the lid 22 closed. It has a switching unit 120 that switches from a non-clamped state to a clamped state in which one tube is clamped.

Therefore, when the fusing-joining operation (position exchange operation in the present embodiment) is stopped in the middle due to the malfunction of the tube joining device 1, the lid portion 22 is left closed and the switching portion 120 separates. The clamp 110 can be switched to the clamped state to block the flow path of one tube. Then, one of the tubes whose flow path is blocked can be removed from the housing 10 together with the detachment clamp 110. Therefore, when the fusing-joining operation is stopped in the middle, it can be removed from the tube joining device 1 while maintaining the aseptic state of one tube.

Further, the release clamp 110 includes a lock portion 113 that maintains the clamp state. Therefore, when one tube clamped by the detachment clamp 110 is removed from the housing 10, for example, even if the detachment clamp 110 and one tube are unintentionally dropped or the like and an impact or the like is applied to the detachment clamp 110. , The clamped state is not released, and the sterile state of one tube can be preferably ensured.

Further, the detachment clamp 110 is provided on the lid portion 22 so as to be removable from the first clamp member 111 which is detachably provided on the housing 10, and is connected to the first clamp member 111 and is connected to the first clamp member 111. A second clamp member 112, which can clamp the tube of the above, is provided. The switching portion 120 connects the second clamp member 112 to the first clamp member 111 by bringing the second clamp member 112 relatively close to the first clamp member in a state where the lid portion 22 is closed. Therefore, the switching portion 120 can easily switch the release clamp 110 from the non-clamping state to the clamped state in the state where the lid portion 22 is closed.

Further, the first clamp member 111 includes a storage space SP capable of accommodating the second clamp member 112, and the second clamp member 112 has a holding portion 112b for sandwiching one tube while being housed in the accommodation space SP. I have. Therefore, the flow path of one tube can be suitably blocked by the holding portion 112b.

Further, the first clamp member 111 is a second clamp member 112 so as to clamp the holding portion 111b that holds one tube and the one tube that the second clamp member 112 is held by the holding portion 111b. 1 It is provided with a guide surface 111c for guiding the approaching movement with respect to the clamp member. Therefore, the first clamp member 111 functions as a tube holding portion for holding the tube when the fusing-joining operation is normally performed. Then, when the fusing-joining operation suddenly stops in the middle unintentionally, one tube can be clamped by connecting the first clamp member 111 and the second clamp member 112. Further, since the second clamp member 112 is guided by the guide surface 111c when approaching the first clamp member 111, one tube can be suitably clamped.

Further, the switching portion 120 includes an operation lever 121 for the user M to perform an operation of switching the release clamp 110 from the non-clamped state to the clamped state, and the operation lever 121 is covered with a removable protective cover 140. .. Therefore, when the fusing-joining operation is normally performed, the operating lever 121 cannot be visually recognized by the user, and the operating lever 121 can be prevented from being used. On the other hand, when the fusing-joining operation is unintentionally stopped in the middle, the user M can remove the protective cover 140 and operate the operation lever 121.

Further, a movable side pressing portion 25b that rotates one side of the blown first tube T1 and one side of the second tube T2 to switch positions, and a rotation detection sensor 150 that can detect the rotation stop of the movable side pressing portion 25b, and movable. Further, it has a notification unit 70 that notifies the user M that the release clamp 110 is switched from the non-clamped state to the clamped state by operating the operation lever 121 when the rotational operation of the side pressing unit 25b is stopped. There is. Therefore, the user M knows through the notification unit 70 that the operation of rotating one side of the fused first tube T1 and one side of the second tube T2 to switch the positions has stopped, and based on the information, the user M knows that the operation of switching the positions has stopped. The operation lever 121 can be operated.

Further, a clamp detection sensor 130 capable of detecting the clamp state of the detachment clamp 110 is further provided, and when the clamp detection sensor 130 detects the clamp state of the detachment clamp 110, the notification unit 70 tells the user M together with the detachment clamp 110. Notify that the tube will be removed from the housing 10. Since the lid 22 is opened when the detachment clamp 110 is in the clamped state, the sterility of one tube can be kept even more suitable.

For example, in the above embodiment, the first tube is a dialysate tube connected to the peritoneal dialysate bag via a branch tube, and the second tube is the side of the peritoneal catheter of the patient used for peritoneal dialysis. The form of the tube was described. However, the tube is not particularly limited as long as it is a tube to be subjected to pressure bonding by switching the position of the end portion after fusing. For example, the first tube may be a tube connected to a plurality of peritoneal dialysate bags and drainage tanks and to a device that automatically dialysates peritoneal fluid. Further, the first tube and the second tube are not limited to the tubes used for peritoneal dialysis.

Further, for example, in the above embodiment, when the position exchange operation for exchanging the positions of one side of the first tube and one side of the second tube after fusing is stopped in the middle, the release clamp is switched from the non-clamped state to the clamped state. Explained. However, the detachment clamp can be switched from the non-clamped state to the clamped state when either the fusing-joining operation (for example, the fusing operation or the pressure joining operation) is stopped in the middle and the joining is not completed. good. This allows the tube to be removed from the housing while maintaining the sterility of the tube.

Further, for example, in the above embodiment, the form in which the detachment clamp includes the first clamp member and the second clamp member has been described. However, the detachment clamp may be composed of, for example, a single member.

Further, for example, in the above embodiment, the embodiment in which the switching portion for switching the release clamp from the non-clamped state to the clamped state is configured by an operation lever has been described. However, the switching unit may be configured to automatically switch the release clamp from the non-clamped state to the clamped state, for example.
