Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a peritoneal dialysis tube unclogging and sealing device. Background Art

[0002] Peritoneal dialysis is a home treatment for patients with end-stage renal disease (uremia). The peritoneal dialysis fluid is passed in and out through a peritoneal dialysis tube inserted into the abdominal cavity every day, ultrafiltering excess water and toxins in the body to achieve the therapeutic effect. The peritoneal dialysis tube is the lifeline of peritoneal dialysis patients, but fibrin, bacterial clumps or impurities in the abdominal cavity can block the side holes or main holes of the intra-abdominal section of the tube, causing the peritoneal dialysis fluid to flow out and infuse poorly. In various dialysis centers, the incidence of mechanical complications related to such peritoneal dialysis tubes is between 6-55%. If not handled properly and in a timely manner, it will lead to failure of dialysis technology and even endanger life.

[0003] In this situation, it is often necessary to seek help from the hospital's full-time doctors and nurses, who use a 20ml syringe to extract one tube of heparin or one tube of urokinase and 20ml of normal saline, and inject them into the peritoneal dialysis tube to seal the tube in order to fully dissolve impurities such as fibrin attached to the tube. However, for patients with severe tube blockage, unblocking is difficult and laparoscopic surgery is often required to deal with the tube problem, which causes great damage to the patient's body, high medical costs, and is time-consuming and laborious for medical staff.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The present invention aims to solve the problem that the existing peritoneal dialysis tube cannot be effectively unblocked and causes great damage to the patient's body. Figure 1-6 As shown, the following technical scheme is provided: a peritoneal dialysis tube unclogging and sealing device, comprising an unclogging device 1 and a tube sealing device 2, wherein the unclogging device 1 comprises an unclogging tube 11 for extending into the peritoneal dialysis tube A, wherein a first end of the unclogging tube 11 is provided with a balloon 13 connected to the inside of the unclogging tube 11, and a nylon brush 14 is provided on the outside of the unclogging tube 11 near the balloon 13, and a fixing seat 12 is sleeved on the outside of the second end of the unclogging tube 11, wherein the unclogging tube 11 and the fixing seat 12 are movably matched, wherein the unclogging tube 11 is sleeved on the outside of one end of the peritoneal dialysis tube A and fixed, and an injection hole 18 is provided on the end surface of the fixing seat 12, wherein the injection hole 18 and the space between the peritoneal dialysis tube A and the unclogging tube 11 are spaced apart from each other. The sealing device 2 is pre-filled with urokinase solution 23 and saline solution 27. One end of the sealing device 2 is used to inject a mixed solution of urokinase solution 23 and saline solution 27 directly into the peritoneal dialysis tube A or into the gap between the peritoneal dialysis tube A and the dredging tube 11 through the injection hole 18. The dredging device 1 and the sealing device 2 form a matching dredging and sealing device, which is easy to use. The fibrin and impurities in the peritoneal dialysis tube A can be discharged from the end or the side hole through the balloon 13 and the brush 14 on the dredging device 1, and the impurity fragments can be dissolved by the mixed solution of urokinase solution 23 and saline solution 27 while the balloon 13 and the brush 14 are working, so the dredging efficiency is high and the dredging completion degree is high.

[0024] Specifically, Figure 1 As shown, the tube sealing device 2 is in a sealed state when not in use and the solution inside cannot be pushed out. Since the structures of the unblocking device 1 and the tube sealing device 2 are relatively simple and the cost is relatively low, they can be used as disposable medical supplies. After production and manufacturing, the two are sealed with a sealing bag 3. When in use, the sealing bag 3 can be torn open and the solution can be taken out and used directly.

[0025] Among them, the function of the dredging device 1 is to discharge or chop up the fibrin and impurities inside the peritoneal dialysis tube A. During the use of the peritoneal dialysis tube A, its impurities are mainly concentrated in the side holes on the front and side walls of the peritoneal dialysis tube A. Therefore, when the first end of the dredging tube 11 moves to the front of the membrane dialysis tube A, the balloon 13 will expand after water is injected into the dredging tube 11. The expanded balloon 13 can push the impurities or fibrin forward or squeeze them into the side holes on the side walls of the membrane dialysis tube A as the dredging tube 11 moves. Then, when the nylon brush 14 passes through the side hole, the nylon brush 14 can be inserted into the side hole to push out and chop up the impurities or fibrin. The nylon brush 14 can clean the side holes over a large range as the dredging tube 11 moves axially or rotates, and the cleaning effect is very good.

[0026] After the peritoneal dialysis tube A is cleaned by the clearing tube 11, a mixed solution of urokinase solution 23 and saline solution 27 can be injected into the peritoneal dialysis tube A using the tube sealing device 2 to dissolve the remaining impurities and fibrin fragments. Since the volume of the impurities and fibrin fragments is very small, the dissolution efficiency is very high.

[0027] When the tube sealing device 2 is injected into the peritoneal dialysis tube A, the clearing tube 11 may not be withdrawn from the peritoneal dialysis tube A. The mixed solution is injected into the gap between the peritoneal dialysis tube A and the clearing tube 11 through the injection hole 18. After dissolving for a period of time, the peritoneal dialysis tube A is cleaned through the clearing tube 11, which can better improve the cleaning efficiency.

[0028] Therefore, the entire unblocking and cleaning process is not only highly efficient and effective, but also flexible and diverse in operation, and can be used according to different blockage conditions of peritoneal dialysis tube A.

[0029] In this embodiment, if Figure 2 As shown, the first end of the clearing tube 11 is provided with a blunt tail end portion 15, and the surface of the blunt tail end portion 15 is an arc surface. The blunt tail end portion 15 can guide the guide wire into the peritoneal dialysis tube without damaging the intestine and other abdominal organs. The blunt tail end portion 15 can be made of metal material and has a good guiding and unblocking effect.

[0030] In this embodiment, if Figure 2 As shown, the nylon brush 14 is arranged obliquely along the length direction of the clearing tube 11, which facilitates the clearing tube 11 to enter the peritoneal dialysis tube A, and can be inserted into the opening on the side wall of the peritoneal dialysis tube A when the clearing tube 11 moves, wherein the inclination angle and length of the brush 14 can be set as needed.

[0031] In this embodiment, if Figure 4As shown, the tube sealing device 2 comprises a syringe 21 and a piston 24 disposed in the syringe 21, a push rod 26 is disposed at the rear end of the piston 24, a pointed rod 25 is disposed at the front end of the piston 24, a sealing soft capsule 22 is disposed inside the syringe 21, a urokinase solution 23 is disposed in the sealing soft capsule 22, physiological saline 27 is pre-filled between the sealing soft capsule 22 and the front end liquid outlet 28 of the syringe 21, and when the push rod 26 pushes the piston 24 to move, the pointed rod 25 can pierce the sealing soft capsule 22 to allow urokinase to flow out. The solution 23 is mixed with the physiological saline solution 27 and can be discharged from the front end liquid outlet 28. When not in use, a sealing cap is placed on the front end liquid outlet 28, and the piston 24 cannot be pushed at this time, thereby ensuring the safety of transportation. The sealing soft capsule 22 can be made of PVC film. The sealing soft capsule 22 can be punctured by the pointed rod 25 first because of the buoyancy arranged on the upper part of the physiological saline solution 27. After puncture, the urokinase solution 23 and the physiological saline solution 27 can be mixed. When in use, the tube sealing device 2 can be shaken to improve the mixing efficiency.

[0032] like Figure 2-3 As shown, locking studs 17 are radially installed on the side wall of the fixing seat 12, and the locking studs 17 are against the outer wall of the peritoneal dialysis tube A, so that the fixing seat 12 and the peritoneal dialysis tube A can be fixed and the dredging tube 11 can be operated. When the fixing seat 12 is connected and fixed to the peritoneal dialysis tube A, the expansion and rotation of the dredging tube 11 have a support point, which is convenient for operation. If the dredging tube 11 needs to be withdrawn from the peritoneal dialysis tube A, the fixing seat 12 can be separated from the peritoneal dialysis tube A. At the same time, in order to facilitate the operation of the dredging tube 11, the second end of the dredging tube 11 is symmetrically provided with operating side pieces 19 on both sides, so that the dredging tube 11 can be moved back and forth or rotated by holding the operating side pieces 19.

[0033] In this embodiment, a detachable pipe cap 16 is installed at the second end of the dredging pipe 11 to seal the dredging pipe 11 .
