Description

Technical Field

[0001] The present invention belongs to the technical field of peritoneal dialysis, and in particular relates to a peritoneal dialysis fluid exchange auxiliary device. Background Art

[0002] Peritoneal dialysis, also known as peritoneal dialysis, utilizes the semi-permeable membrane characteristics of the peritoneum. The prepared dialysis fluid is injected into the patient's peritoneal cavity through a catheter at regular intervals. The dialysis fluid in the peritoneal cavity is then continuously replaced to remove metabolic waste and toxic substances from the patient's body. It can also balance electrolytes and acid-base imbalances in the body, and is often used to treat patients with end-stage renal disease.

[0003] Patent number CN202221189937.4 is an auxiliary connection device for peritoneal dialysis fluid exchange, including a mounting egg, a mounting egg, a first connecting shell, a second connecting shell, a Y-shaped connector and an infusion tube. When the peritoneal dialysis fluid Y-shaped connector needs to be connected to an external short tube, the first connecting shell and the second connecting shell can be held at the same time and closed. The second connecting shell can drive the external short tube to move quickly to the inside of the peritoneal dialysis fluid Y-shaped connector. A seal is provided between the external short tube and the peritoneal dialysis fluid Y-shaped connector. The sealing ring prevents the leakage of dialysate and is convenient for visually impaired operators to operate by themselves without accidentally touching the interface of the external short tube; the patent number is CN201920235469.1, which is a one-handed peritoneal dialysis fluid exchange auxiliary device, including a base, a bottom, a fixing plate, a disassembly hole, a groove, and a lower rotating arm. A groove is provided above the other end of the lower rotating arm, which is compatible with the handheld part of the external short tube. The middle part of the fixing plate is provided with an iodine liquid micro-cover packaging bag upright position fixing groove that is compatible with the iodine liquid micro-cover packaging bag upright position. The device can replace the function of the patient's disabled hand and help the patient to perform peritoneal dialysis fluid exchange with one hand on the healthy side. In the above scheme, it is mentioned that the first connecting shell and the second connecting shell must be held at the same time to complete the fluid exchange operation, and the fluid exchange method using the groove of the lower rotating arm to match the short tube handpiece may cause the problem of parts falling, which can easily cause contamination of the dialysate connector. When the patient changes the fluid, the dialysate connector cannot be accurately connected to the peritoneal dialysis short tube, which is not convenient for multiple fluid exchanges. In view of this, we propose a peritoneal dialysis fluid exchange auxiliary device.

An adjustment component 2 is provided above the connector 10. The adjustment component 2 includes a support plate 20 and two long shafts 21 arranged on the top of the support plate 20. A fixed adjustment plate 22 and a dynamic adjustment plate 23 are provided on the two long shafts 21 from front to back, which play a role in supporting the fixed adjustment plate 22 and the dynamic adjustment plate 23. The lifting rod 11 is fixed to the support plate 20 by the provided connector 10. The top of the lifting rod 11 is threadedly fixed to the connector 10 by a bolt, which is convenient for disassembly and assembly.

[0038] The movable assembly 1 also includes a chassis 12 at the bottom thereof, and a ball support 120 for moving the peritoneal dialysis fluid exchange auxiliary device is installed on the chassis 12. The ball support 120 drives the movable assembly 1 to move as a whole, and the balls in the ball support 120 can roll in multiple directions, which is convenient for controlling the overall direction of the movable assembly 1. A lifting rod 11 is provided on the top of the chassis 12, and the lifting rod 11 is used to adjust the height of the adjustment assembly 2. The lifting rod 11 is embedded with a plurality of spring protrusions 110 for adjusting its height. By pressing the spring protrusions 110 toward the axial direction of the lifting rod 11, the spring protrusions 110 are compressed, and the lifting rod 11 is lifted up and down. When the spring protrusions 110 are released, the spring protrusions 110 are extended from the adjustment holes 111 to fix the lifting rod 11. By controlling the use height of the adjustment assembly 2, the height of the support clamp assembly 3 and the fixing clamp assembly 4 can be adjusted, which is convenient for the patient to stand or lie down.

[0039] Specifically, the fixed adjustment plate 22 is provided with a support clamp assembly 3 for clamping the dialysate connector. The support clamp assembly 3 includes a first concave plate 30 and two brackets 31. The first concave plate 30 is slidably connected to the top of the fixed adjustment plate 22. The two brackets 31 are distributed side by side on the top of the first concave plate 30. Two limit members 220 are provided on the outer wall of the fixed adjustment plate 22 near the rear side of the support clamp assembly 3. The first concave plate 30 drives the two brackets 31 to slide on the fixed adjustment plate 22 between the two limit members 220.

[0040] The bracket 31 includes a base plate 310 fixedly connected to the top of the horizontal end of the first concave plate 30, two sleeve plates 311 respectively arranged on the left and right vertical ends of the base plate 310, and two first springs 312 fixedly connected to the sleeve plate. The ends of the two first springs 312 are provided with a contact plate 313. When the dialysate connector is inserted between the contact plates 313, the two first springs 312 on each side of the contact plate 313 are compressed into the sleeve plate 311. The ends of the two long shafts 21 are fixed to the top of the support plate 20 through the fixing block 210. The bottom center of the support plate 20 is welded and fixed to the top of the connector 10 to increase the structural strength of the connection between the support plate 20 and the connector 10. The ends of the fixed adjustment plate 22 are respectively sleeved and fixed with the two long shafts 21 to prevent the support and clamp assembly 3 from shaking left and right during use. The ends of the dynamic adjustment plate 23 are respectively slidably connected with the two long shafts 21. When the peritoneal dialysis short tube is clamped in the hole 43, the movable adjustment plate 23 is slid to make the tube mouth of the peritoneal dialysis short tube dock with the dialysate connector, and the peritoneal dialysis short tube is rotated to make the peritoneal dialysis short tube and the dialysate connector screwed and fixed.

[0041] Furthermore, the first concave plate 30 also includes a second concave plate 301, which is fixed to the first concave plate 30 by end bolts 302. The second concave plate 301 is provided to fix the first concave plate 30, thereby ensuring the stability of the first concave plate 30 when sliding on the fixed adjustment plate 22.

[0042] In addition, the base plate 310 is arranged in a concave shape, and the vertical ends on both sides of the base plate 310 are respectively engaged with each sleeve plate 311, the two contact plates 313 are symmetrically arranged, and a number of rubber sheets 3130 are adhered to the inner wall of each contact plate 313. The arrangement of the base plate 310 facilitates the disassembly and assembly of the sleeve plate 311, and facilitates the removal of the sleeve plate 311 and the contact plate 313 for disinfection and cleaning. The arrangement of the rubber sheet 3130 increases the friction when the dialysate connector is clamped, preventing the dialysate connector from rotating, promoting the screw connection between the peritoneal dialysis short tube and the dialysate connector, and improving the fluid exchange efficiency.

[0043] In the present invention, the fixing clamp assembly 4 includes a base 40 and a mounting groove 401 at its bottom end, the movable adjustment plate 23 is inserted into the mounting groove 401, and the two vertical ends at the bottom of the base 40 are fixed by end bolts 302, so that the fixing clamp assembly 4 is fixed to the movable adjustment plate 23, the fixing clamp assembly 4 includes a base 40, a lower clamping plate 41 and an upper clamping plate 42, the lower clamping plate 41 is fixedly connected to the top of the base 40, the upper clamping plate 42 and the lower clamping plate 41 are hinged to form an open and covered state, and a clamping hole 43 is formed after the lower clamping plate 41 and the upper clamping plate 42 are hinged and covered, which is used to clamp the peritoneal dialysis short tube. The peritoneal dialysis short tube is placed in the clamping hole 43 so that the head end of the peritoneal dialysis short tube is exposed to the outside of the clamping hole 43. The upper clamping plate 42 and the lower clamping plate 41 are provided to facilitate the disassembly and assembly of the peritoneal dialysis short tube.

[0044] In the above scheme, the upper splint 42 is provided with two symmetrical placement grooves 420, which are arranged at one end away from the hinge of the upper splint 42. The upper splint 42 is provided with a guide hole 423, which is arranged at one end close to the hinge of the upper splint 42. A T-shaped block 421 is provided in the placement groove 420, and the T-shaped block 421 slides in the placement groove 420. A blocking member 4210 is provided on the outer wall of the T-shaped block 421 on the side away from the placement groove 420. After the blocking member 4210 passes through the guide hole 423 and extends into the clamping hole 43, after the peritoneal dialysis short tube is placed into the guide hole 423, the arc-shaped part at the end of the blocking member 4210 is used to limit the outer wall of the middle and rear tube body of the peritoneal dialysis short tube to prevent the peritoneal dialysis short tube from sliding in the guide hole 423, thereby ensuring that the peritoneal dialysis short tube can rotate stably in the guide hole 423, facilitating the fluid exchange operation of the peritoneal dialysis short tube and improving the fluid exchange efficiency.

[0045] It is worth noting that a pull rod 422 is plugged and fixed on the T-block 421. The pull rod 422 includes a top cap 4220 set at the center of the top of the T-block 421, an outer tube 4221 plugged and fixed inside the T-block 421, and an inner tube 4223 clamped in the outer tube 4221. The top of the inner tube 4223 is fixedly connected to the bottom of the top cap 4220 through a second spring 4222, and the bottom end of the top cap 4220 is inserted into the pipe opening at the top of the outer tube 4221. By pulling up the top cap 4220, so that the second spring 4222 drives the inner tube 4223 to move upward, adjust the T-block 421 on each side to slide in the placement slot 420, and after inserting the bottom end of the inner tube 4223 into one of the positioning holes 410, control the T-block 421 to slide in the placement slot 420. Through the provided positioning holes 410, it is convenient to fix peritoneal dialysis short tubes of different lengths. According to the size of the peritoneal dialysis short tube, the bottom end of the inner tube 4223 can be inserted into the positioning holes 410 at different positions.

[0046] The working principle of the peritoneal dialysis fluid exchange auxiliary device of the present invention is specifically as follows:

[0047] First, place the peritoneal dialysis short tube into the recess of the lower splint 41 so that the head end of the peritoneal dialysis short tube is exposed through the clamping hole 43, then close the upper splint 42 and the lower splint 41, and pull the two pull rods 422 upward respectively. The pull rods 422 drive the T-block 421 to slide in the placement groove 420, and drive the blocking member 4210 to move in the clamping hole 43, and then make the arc portion of the blocking member 4210 abut against the tube body at the rear end of the peritoneal dialysis short tube, and the arc portion of the other blocking member 4210 abut against the tube body at the middle end of the peritoneal dialysis short tube. Then, the dialysate connector is inserted into the bracket 31 on the rear side of the clamp assembly 3. The rubber sheet 3130 contacts the outer wall of the dialysate connector tube, so that the two contact plates 313 clamp the rear end of the dialysate connector. The first concave plate 30 is pushed and abutted against the fixed block 210 at the front end of the adjustment assembly 2, so that the dialysate connector is directly opposite the peritoneal dialysis short tube. Finally, the movable adjustment plate 23 is pushed toward the clamp assembly 3 to connect the peritoneal dialysis short tube with the dialysate connector, completing the peritoneal dialysis fluid exchange operation.

[0048] It is worth noting that the bracket 31 on the front side of the clamp assembly 3 is used to clamp the spare dialysate connector for peritoneal dialysis fluid exchange. After the first dialysis is completed, the second fluid exchange dialysis can be connected, and the movable adjustment plate 23 is pushed away from the clamp assembly 3 to separate the peritoneal dialysis short tube from the dialysate connector used for the first time. Then the first concave plate 30 is pushed and the first concave plate 30 is abutted against the fixed block 210 at the rear end of the adjustment assembly 2, so that the dialysate connector for the second dialysis is facing the peritoneal dialysis short tube, and the above-mentioned fluid exchange operation is repeated to dock the peritoneal dialysis short tube with the dialysate connector to complete the second fluid exchange operation of peritoneal dialysis. Finally, the dialysate connector used for the second time is taken out to ensure that one of the brackets 31 can be used for fluid exchange.
