Description

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

  As a technique for joining resin tubes and the like, there is conventionally known a joining method in which the ends of each resin tube are melted and the melted ends are pressed against each other by pressure bonding. Such a technique is widely used in various industrial fields. As an example, application to medical techniques such as a peritoneal dialysis method has been attempted.

  The peritoneal dialysis method uses a tube (catheter) embedded in the abdominal cavity of a patient to put a predetermined dialysate into the body, and then removes water and waste products transferred to the dialysate through the peritoneum. Is the method. When the dialysate is put into the body, the tube embedded in the patient is joined in a liquid-tight manner to the back tube containing the dialysate. Also, when the dialysate is drained from the body, the tube embedded in the patient is joined to the drain back tube in a fluid-tight manner.

  As described above, since one of the tubes to be joined is embedded in the abdominal cavity of the patient, careful attention must be paid to the work so that each tube is not contaminated during the joining work. In view of such a point, a tube joining apparatus has been developed that enables the ends of two resin tubes to be fused and automatically joined in a sterile state.

  The tube joining apparatus described in the said patent document 1 melt | disconnects the edge part of the two tubes arrange | positioned side by side, and replaces the position of the one side of the two melted tubes, and joins them. Specifically, the two tubes are set in a state in which they are arranged in two accommodating portions provided on both sides of the fusing position. Then, after fusing, one side of the two tubes is rotated 180 degrees, and the positions are replaced and joined. At this time, the accommodating portion provided on the side where the positions are exchanged is configured to rotate 180 degrees in conjunction with the rotation operation of the two tubes so as not to hinder the position exchange operation. For this reason, the structure of the accommodating portion becomes relatively complicated.

  The present invention has been made in view of the above problems, and provides a tube joining apparatus that can hold a tube without hindering the work of replacing the position of the tube after fusing and has a relatively simple structure. The purpose is to do.

And a tube pressing portion 25 that presses and crushes the first tube T1 and the second tube T2 with each other as the lid portion 22 approaches the pedestal 13 relatively. Hereinafter, the configuration of each part of the clamp part 20 will be described.

  First, the pedestal 21 will be described.

  The pedestal 21 includes a first pedestal 211 provided on the fixed side X2 of the first tube T1 and the second tube T2, and a second pedestal 212 provided on the replacement side X1 of the first tube T1 and the second tube T2. ing. A gap 21a is provided between the first pedestal 211 and the second pedestal 212 along the extending direction of the first tube T1 and the second tube T2. The gap 21a is a gap through which the wafer WF passes when the wafer WF before use moves to the fusing position, or when the used wafer WF is sent out of the housing 10.

  Each of the first pedestal 211 and the second pedestal 212 is provided with an engaged portion 213 for hooking and fixing an engaging claw 225 of the lid portion 22 described later.

  Next, the lid part 22 will be described.

  The lid portion 22 includes a first clamp arm 221 provided so as to be rotatable with respect to the first pedestal 211, a second clamp arm 222 provided so as to be rotatable with respect to the second pedestal 212, and a first clamp. A cover 223 that covers the arm 221 and the second clamp arm 222, and a grip portion 224 that can be rotated with respect to the clamp arms 221 and 222 and can be gripped by the user M are provided.

  Each clamp arm 221, 222 is configured to be individually rotatable.

  The cover 223 integrally covers the first clamp arm 221 and the second clamp arm 222. For this reason, as shown in FIG. 2, in the state which closed the cover part 22, the cover 223 covers the area | region where the 1st base 211, the 2nd base 212, and the fusing-joining between them are performed.

  As shown in FIG. 5, the grip portion 224 includes an engaging claw 225 that can be engaged with the engaged portion 213 of the base 21.

  Next, the tube holding part 23 will be described.

  As shown in FIG. 5, the tube holding unit 23 includes a first holding unit 231 and a second holding unit 232 (corresponding to a “fixed holding unit”) that fixedly holds the fixed side X2 of each tube T1, T2. A third holding portion 233 (corresponding to a “movable holding portion”) that movably holds the replacement side X1 of each tube T1, T2, and the third holding portion 233 are held from the holding state where the tubes T1, T2 are held. A release unit 234 that can be switched to the released release state and a restoration unit 235 that can switch the third holding unit 233 from the release state to the hold state are provided. Hereinafter, the structure of each part of the tube holding part 23 will be described.

  First, the first holding unit 231, the second holding unit 232, and the third holding unit 233 will be described.

  The first holding part 231 is fixed to the upper surface of the first pedestal 211. The first holding portion 231 includes a concave first groove portion 231a into which the first tube T1 can be fitted, and a concave second groove portion 231b into which the second tube T2 can be fitted.

  As shown in FIG. 9A, the first groove 231a and the second groove 231b are provided so as to be aligned in a direction (oblique direction D1) inclined by an angle θ with respect to the height direction Z of the housing 10. . For this reason, the 1st tube T1 and the 2nd tube T2 are hold | maintained at the 1st holding | maintenance part 231 in the state juxtaposed in the diagonal direction D1. In addition, the 1st groove part 231a arrange | positioned in the back | inner side of the juxtaposition direction D1 of the 1st tube T1 and the 2nd tube T2 is arrange | positioned in the position of the height direction Z of the housing | casing 10 higher than the 2nd groove part 231b. .

  In addition, each of the groove portions 231a and 231b is provided on the upper surface side of the first holding portion 231 so as to be recessed in a concave shape along a direction D2 orthogonal to the oblique direction D1. For this reason, each tube T1, T2 is set so that it may insert from the direction D2 orthogonal to the juxtaposition direction D1. For this reason, the user M can insert and set each tube T1, T2 easily in the state which opened the cover part 22. FIG.

  As shown in FIG. 5, the second holding part 232 is fixed to the side surface of the first pedestal 211 adjacent to the first holding part 231. Similarly to the first holding part 231, the second holding part 232 includes a concave third groove part 232a into which the first tube T1 can be fitted, and a concave fourth groove part 232b into which the second tube T2 can be fitted. ing. The third groove portion 232a and the fourth groove portion 232b are provided so as to be aligned in the oblique direction D1, similarly to the first groove portion 231a and the second groove portion 231b of the first holding portion 231.

  As shown in FIG. 9B, the third holding portion 233 includes a base portion 233a that is rotatably provided on the side surface of the second pedestal 212, and a bent portion 233b that is bent from the base portion 233a and continues. Yes.

  The bent portion 233b is provided with a concave fifth groove portion 233c capable of fitting the replacement side X1 of the first tube T1 and a concave sixth groove portion 233d capable of fitting the replacement side X1 of the second tube T2.

  In the third holding part 233, the fifth groove part 233c and the sixth groove part 233d shown in FIG. 9B are arranged along the oblique direction D1, and each of the tubes T1, T2 together with the first holding part 231 and the second holding part 232 is provided. Can be moved between a position where it can be held (referred to as “holding position P0”) and a position where the holding is released (referred to as “release position P1”) shown in FIG. 12B.

  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 of the holding portions 231, 232, 233, an imaginary line (indicated by a chain line in the drawing) connecting the axis of the first tube T 1 and the axis of the second tube T 2 is 45 with respect to the height direction Z. The first tube T1 and the second tube T2 are held so as to form an angle of degrees. However, in the present embodiment, the angle θ is not particularly limited as long as it is larger than 0 degree and smaller than 90 degrees.

  Thus, each holding part 231, 232, 233 hold | maintains each tube T1, T2 separately in the state juxtaposed in the diagonal direction D1 with respect to the height direction Z of the housing | casing 10. As shown in FIG. As shown in FIG. 9A, the user M sits on a chair or the like and uses the tube joining apparatus 1 placed on the table or the like so as to look from diagonally above, so the user M does not change his posture. Each tube T1, T2 can be set in each holding part 231, 232, 233. In addition, the user M can easily visually check whether or not the set tubes T1 and T2 are properly set (whether there is twisting or the like).

  For example, when the angle θ = 0 degrees (when the first tube T1 and the second tube T2 are juxtaposed in the height direction Z), the eyes of the user M are positioned obliquely above the tube bonding apparatus 1. Therefore, the grooves 231b, 232b, 233d and the second tube T2 disposed on the lower side (the pedestal 21 side) are the grooves 231a, 232a, 233c and the first tube T1 disposed on the upper side (the lid 22 side). It is difficult to see because it is hidden behind. For this reason, in order to confirm whether each tube T1, T2 is set appropriately, the user M needs to look down like crouching.

  Further, for example, when the angle θ = 90 degrees (when the first tube T1 and the second tube T2 are juxtaposed in the horizontal direction), the eyes of the user M are positioned obliquely above the tube bonding apparatus 1. The grooves 231a, 232a, 233c and the first tube T1 disposed on the back side are hidden behind the grooves 231b, 232b, 233d and the second tube T2 disposed on the near side and are not easily visible. For this reason, in order to confirm whether each tube T1 and T2 are set appropriately, the user M needs to look into the back so that he may lean out to the back side.

  In addition, from the viewpoint of visibility as to whether or not the tubes T1 and T2 are properly set, the angle θ is preferably 30 degrees or more and less than 90 degrees, for example.

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

  As shown in FIG. 5, the release portion 234 includes a flat surface 234 a that continues to the side surface of the second clamp arm 222, and a protrusion that protrudes from the base portion 233 a of the third holding portion 233 toward the flat surface 234 a of the second clamp arm 222. 234b.

  As shown in FIG. 11B, the protrusion 234 b provided on the third holding part 233 is a flat surface provided on the cover part 22 as the cover part 22 moves closer to the housing 10. 234a abuts. In this embodiment, after a tube pressing portion 25 described later sandwiches the first tube T1 and the second tube T2 (see FIG. 10A) and before the lid portion 22 is completely closed (FIG. 12). (See (B)), the protrusion 234b contacts the flat surface 234a. From the state of FIG. 11B in which the protrusion 234b is in contact with the flat surface 234a, when the lid portion 22 is further pushed down (relatively approaching the housing 10), the third holding portion 233 is separated from the lid portion 22. Is pushed down in the direction D3 to release the holding of the tubes T1 and T2. As described above, the release unit 234 is configured to retract the third holding unit 233 from the holding position P0 to the release position P1 in accordance with the operation in which the lid unit 22 approaches the housing 10 relatively.

  As shown in FIG. 9B, the restoring portion 235 is a cam 235a that can push up the third holding portion 233 in conjunction with the operation in which the second clamp arm 222 of the lid portion 22 moves away from the housing 10. It has.

  The cam 235 a has a substantially fan-shaped outer shape when viewed from the side of the housing 10. The cam 235 a is fixed near the rotating portion of the second clamp arm 222. For this reason, the cam 235a also rotates in conjunction with the rotation of the second clamp arm 222. The curved surface of the cam 235a abuts against the bottom surface of the third holding portion 233 in a state where the lid portion 22 is opened to some extent, and keeps the third holding portion 233 at the holding position P0. As shown in FIG. 10 (B), the curved surface of the cam 235a is formed such that when the lid portion 22 is brought relatively close to the housing 10, the protrusion 234b of the release portion 234 comes into contact with the flat surface 234a. It is separated from the third holding part 233. For this reason, when shifting from the open state to the closed state of the lid portion 22, the cam 235 a does not prevent the third holding portion 233 from moving from the holding position P 0 to the releasing position P 1 by the releasing portion 234. On the other hand, when the lid portion 22 is shifted from the closed state to the opened state, the cam 235a comes into contact with the third holding portion 233 and pushes up the third holding portion 233. As a result, the third holding unit 233 returns from the release position P1 to the holding position P0.

  In this way, the third holding unit 233 is configured to be movable between the holding position P0 and the release position P1 by the release unit 234 and the restoration unit 235. For this reason, the 3rd holding | maintenance part 233 does not prevent the position exchange operation | work which replaces the position of the one side of the 1st tube T1 and the 2nd tube T2 after the cutting performed with the cover part 22 closed. Moreover, since it is not necessary to rotate the 3rd holding | maintenance part 233 in response to the movable side pressing part 25b which performs the position exchange operation mentioned later, the tube joining apparatus 1 can be made into a comparatively simple structure. Further, in the present embodiment, the release unit 234 retracts the third holding unit 233 from the holding position P0 to the release position P1 after the tube pressing unit 25 described later sandwiches the first tube T1 and the second tube T2. For this reason, the tube pressing portion 25 holds the first tube T1 and the second tube T2 in a state where the replacement side X1 of the first tube T1 and the second tube T2 is held at an appropriate position by the third holding portion 233. Can be pinched.

  Next, the tube detection sensor 24 will be described.

  As shown in FIG. 6, the tube detection sensor 24 is provided in the third groove portion 232a and the fourth groove portion 232b of the second holding portion 232. The tube detection sensor 24 has a function of detecting whether or not the tubes T <b> 1 and T <b> 2 are disposed in the groove portions 232 a and 232 b of the second holding portion 232. Hereinafter, the configuration of the tube detection sensor 24 will be described by taking the tube detection sensor 24 arranged in the third groove portion 232a as an example.

  The tube detection sensor 24 includes a pin 241 that can protrude from a hole provided in the third groove 232a, a base 242 that supports the pin 241, a magnet 243 that is attached to the base 242, and the magnetic force of the magnet 243. A detectable Hall element 244 and a biasing member 245 that applies a biasing force in a direction protruding from the hole to the pin 241 are provided. In this 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 disposed in the third groove portion 232a, the base 242 receives the urging force of the urging member 245 and the base 242 has the second holding portion 232 as shown in FIG. The operation of the pin 241 is regulated by contacting the inner surface of the pin 241. For this reason, the tip end side of the pin 241 protrudes from the hole. In this state, since the magnet 243 is disposed 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 disposed in the third groove portion 232a, the pin 241 and the base 242 are moved into the lumen of the second holding portion 232 by the first tube T1. 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. As described above, the tube detection sensor 24 determines whether or not the first tube T1 is disposed in the third groove portion 232a by the strength of the magnetic force of the magnet 243 that can be detected by the Hall element 244, and further to the back of the third groove portion 232a. Whether or not one tube T1 is pushed in can be detected.

  The tube detection sensor 24 may be provided in the first holding unit 231 or the third holding unit 233.

  Next, the tube pressing part 25 will be described.

  As shown in FIG. 7, the tube pressing portion 25 moves the fixed side X2 of the first tube T1 and the fixed side X2 of the second tube T2 in accordance with the operation in which the lid portion 22 relatively approaches the housing 10.

It is equipped with.

  The urging member 335a is configured by a spring in this embodiment, but as long as the urging force F in the direction from the release position P1 toward the holding position P0 can be applied to the third holding portion 233, the urging member The configuration of 335a is not particularly limited.

  In the state where the lid portion 22 is opened, the stopper 335b has the third holding portion 233 receiving the urging force F from the urging member 335a in the holding position P0 (the fifth groove portion 233c and the sixth groove portion 233d are in the diagonal direction D1. The rotation operation of the third holding portion 233 is restricted so that the third holding portion 233 is positioned at a position where the third holding portion 233 is positioned.

  For this reason, if the cover part 22 is relatively separated from the housing 10, the third holding part 233 returns from the release position P1 to the holding position P0.

  As mentioned above, although the tube joining apparatus according to the present invention has been described through the embodiment, the present invention is not limited to the configuration described in the embodiment, and can be appropriately modified based on the description of the scope of claims. is there.

  For example, in the above embodiment, the first tube is a dialysate tube connected to a peritoneal dialysate bag via a branch tube, and the second tube is a patient's peritoneal catheter side used when performing peritoneal dialysis. The form which is the tube of was demonstrated. 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 that is connected to a plurality of peritoneal dialysate bags and drainage tanks and connected to a device that automatically dialysates peritoneal fluid. Further, the first tube and the second tube are not limited to tubes used for peritoneal dialysis.

  Further, for example, in the above-described embodiment, the first tube is disposed on the back side and the second tube is disposed on the front side. However, the first tube is disposed on the front side, and the second tube is disposed on the back side. May be.

  For example, in the said embodiment, the tube holding | maintenance part demonstrated the form which hold | maintains a 1st tube and a 2nd tube in the state juxtaposed in the diagonal direction. However, the tube holding part may hold the first tube and the second tube in a state of being juxtaposed in a direction orthogonal to the height direction.

  For example, in the above-described embodiment, the tube holding unit has described the form in which the first tube and the second tube are individually held. However, the tube holding part may hold the first tube and the second tube in a stacked state.

  Further, for example, in the above embodiment, the release portion moves the movable holding portion (the third holding portion in the above embodiment) from the holding position to the release position after the tube pressing portion sandwiches the first tube and the second tube. The form to make was explained. However, the release unit, for example, moves the movable holding unit from the holding position to the release position at the same time that the movable holding unit sandwiches the first tube and the second tube (at the same time the lid-side pressing unit contacts the first tube). It may be moved. Also in this case, the movable clamp portion (movable side pressing portion in the above embodiment) holds the first tube and the second tube in a state where the first tube and the second tube are held at appropriate positions by the movable holding portion. Can be held. Therefore, when a movable clamp part pinches | interposes a 1st tube and a 2nd tube, it can prevent suitably that the position of a 1st tube and a 2nd tube shifts | deviates.

  Further, for example, one side of the first tube after fusing and one side of the second tube are rotated by 180 degrees to switch positions, and the other side of the first tube after fusing and the other position of the second tube are held. Explained the form. However, for example, one side of the first tube after fusing and one side of the second tube are rotated 90 degrees, and the other side of the first tube after fusing and the other side of the second tube are rotated 90 degrees in the opposite direction. The position may be changed. In this case, a movable holding part can be provided on both sides of each tube across the fusing position.
