Description

Technical Field

[0001] This utility model specifically relates to a peritoneal dialysis catheter with a balloon for unblocking the balloon, belonging to the field of dialysis catheter technology. Background Technology

[0002] Uremia is the progressive development of various chronic kidney diseases, eventually leading to severe kidney failure. It can cause the retention of various metabolic products, resulting in electrolyte imbalances, acid-base imbalances, and symptoms affecting various systems throughout the body. At this point, patients need dialysis. Dialysis involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood exchanges substances with an electrolyte solution (dialysis fluid) of similar concentration to the body's own through diffusion and convection within and outside the hollow fibers, removing metabolic waste, maintaining electrolyte and acid-base balance, and simultaneously removing excess water. The purified blood is then returned to the body.

[0003] When existing dialysis catheters are inserted into a patient for dialysis, they may shift due to the patient's muscle activity, causing the side holes on the dialysis catheter to be blocked by the patient's muscle tissue, resulting in difficulties in the patient's dialysis process. In this case, the doctor needs to perform a second surgery to adjust the position of the peritoneal dialysis catheter, which will cause secondary harm to the patient and also increase the workload of the doctor.

[0004] Therefore, it is necessary to propose a peritoneal dialysis catheter with a balloon for unblocking the balloon catheter. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a peritoneal dialysis catheter with a balloon for unblocking the balloon catheter.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a peritoneal dialysis catheter with a balloon, comprising a peritoneal dialysis tubing, wherein one end of the peritoneal dialysis tubing has symmetrically opened siphon side holes on its outer circumference, one end of the peritoneal dialysis tubing has symmetrically arranged wall-supporting balloons, one end of the peritoneal dialysis tubing has symmetrically arranged automatic inflation components for inflating the wall-supporting balloons, and a balloon guide tube is inserted into the peritoneal dialysis tubing.

[0007] Furthermore, in order to house the support airbag through the airbag groove, the outer wall of one end of the peritoneal dialysis tubing is symmetrically provided with airbag grooves, and the siphon side holes are evenly provided on the inner wall surface of one side of the airbag groove.

[0008] Furthermore, in order to allow the peritoneal dialysis fluid injected into the patient to enter the siphon side hole through the support balloon, the support balloon is designed with a porous shape, the outer surface of the support balloon is designed with through holes that are interconnected with the siphon side hole, and one side surface of the support balloon is bonded to one side inner wall of the balloon groove.

[0009] Furthermore, in order to inflate the wall-supporting airbag through the inflation port, the peritoneal dialysis tubing has symmetrical and uniform inflation ports on the outer wall of one end, and one end of the inflation port is connected to the wall-supporting airbag.

[0010] Furthermore, in order to enable the gas in the inflation box to communicate with the gas in the wall-supporting airbag, the automatic inflation assembly is connected to the other end of the inflation port. The automatic inflation assembly includes an inflation box, one side surface of which is fixedly installed on one end surface of the peritoneal dialysis tubing. The outer wall surface of one side of the inflation box is uniformly provided with docking holes, and the docking holes are connected to the inflation port.

[0011] Furthermore, in order to provide elastic force to the air wedge block through the air spring, an air piston is inserted into the air box. Spring grooves are provided on both sides of the lower end of the air piston. An air spring is provided in the spring groove, and an air wedge block is provided at one end of the air spring.

[0012] Furthermore, in order to limit the position of the air-push wedge block, and at the same time, under the elastic force of the air-push spring, the locking groove can lock the air-push wedge block. The elastic force of the air-push spring is much greater than the air pressure between the air box, the air hole and the wall-supporting airbag. When the air piston in the air box does not move, the outer wall of the wall-supporting airbag matches the airbag groove. The locking grooves are equidistantly and linearly opened on both sides of the inner wall of the air box. The air-push wedge block slides and locks with the locking groove.

[0013] Furthermore, in order to push the omentum and part of the peritoneal tissue that has been inserted into the peritoneal dialysis tubing out of the siphon side hole through the balloon guide tube, and at the same time reduce the need for doctors to perform secondary surgery on patients, the balloon guide tube includes a polyethylene membrane tube, in which gravity steel balls are evenly arranged, and a tension rope is provided at one end of the polyethylene membrane tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes a polyethylene membrane tube and a gravity steel ball to push the omentum and part of the peritoneal tissue from the patient's abdomen outside the siphon side hole. At the same time, the automatic inflation component and the wall-supporting airbag work together to reduce the possibility of the omentum and part of the peritoneal tissue entering the siphon side hole and causing blockage, thereby improving dialysis efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 As shown, a peritoneal dialysis catheter with a balloon includes a peritoneal dialysis tubing 1, with siphon side holes 2 symmetrically opened on the outer circumference of one end of the peritoneal dialysis tubing 1, a wall-supporting balloon 3 symmetrically arranged at one end of the peritoneal dialysis tubing 1, an automatic inflation assembly 4 for inflating the wall-supporting balloon 3 symmetrically arranged at one end of the peritoneal dialysis tubing 1, and a balloon guide tube 5 inserted into the peritoneal dialysis tubing 1.

[0025] like Figure 4 and Figure 5 As shown, one end of the peritoneal dialysis tubing 1 has symmetrically arranged air bladder grooves on its outer wall. Siphon side holes 2 are evenly arranged on one side of the inner wall surface of the air bladder groove. One side surface of the support air bladder 3 is bonded to one side of the inner wall of the air bladder groove. One end of the peritoneal dialysis tubing 1 has symmetrically and evenly arranged inflation holes 6. One end of the inflation hole 6 is connected to the support air bladder 3. The automatic inflation assembly 4 is connected to the other end of the inflation hole 6. The automatic inflation assembly 4 includes an inflation box 401. One side surface of the inflation box 401 is fixedly installed on one end surface of the peritoneal dialysis tubing 1. One side surface of the inflation box 401 has evenly arranged docking holes 402. The docking holes 402 are connected to the inflation holes 6. An inflatable tube is inserted into the inflation box 401. The inflation piston 403 has spring grooves on both sides of its lower end. A push spring 404 is installed in the spring groove, and a push wedge block 405 is installed at one end of the push spring 404. The inner walls of both sides of the inflation box 401 are provided with locking grooves at equal intervals. The push wedge block 405 and the locking groove slide and lock together, so that when the doctor inserts the peritoneal dialysis tubing 1 into the patient's abdomen, the doctor presses the automatic inflation component 4 at one end of the peritoneal dialysis tubing 1 to reduce the internal space of the automatic inflation component 4, thereby increasing the gas in the wall support balloon 3. This allows one end of the peritoneal dialysis tubing 1 to be supported by the wall support balloon 3 and the internal tissue of the patient's abdomen, thereby reducing the possibility of blockage of the siphon side hole 2.

[0026] like Figure 6 As shown, the balloon guide tube 5 includes a polyethylene membrane tube 501, in which gravity steel balls 502 are evenly arranged. One end of the polyethylene membrane tube 501 is provided with a tension rope 503. By utilizing the soft and tough properties of the polyethylene membrane tube 501 and the flexible bending properties of the gravity steel balls 502, doctors can easily push the soft and tough balloon guide tube 5 into the curved and closed peritoneal dialysis tubing 1 to achieve the purpose of unblocking the peritoneal dialysis tubing 1. At the same time, the gravity steel balls 502 can be made into different diameters as needed.

[0027] In use, the doctor inserts the device into the area where dialysis is required and presses the inflation piston 403 within the automatic inflation assembly 4 of the peritoneal dialysis tubing 1. This causes the inflation piston 403 to compress the gas in the inflation box 401, allowing the gas to move through the inflation port 6 towards the wall-supporting balloon 3. The wall-supporting balloon 3 gradually enlarges, providing support to the patient's abdominal tissues. The wall-supporting balloon 3 has multiple through holes, with a diameter larger than the siphon side hole 2. These through holes are interconnected with the siphon side hole 2, reducing the possibility of blockage. Furthermore, even if the through-hole is blocked, dialysis can still be completed thanks to the flexibility of the support balloon 3. If the patient's abdominal tissue blocks the siphon side hole 2 through the through-hole, the doctor can insert the balloon guide tube 5 into the peritoneal dialysis tubing 1. The balloon guide tube 5 can push the abdominal tissue inside the siphon side hole 2 out of the peritoneal dialysis tubing 1 to ensure normal dialysis. Thus, by using the automatic inflation component 4 in conjunction with the support balloon 3, the possibility of the abdominal omentum wrapping and some peritoneal tissue entering the siphon side hole 2 and causing blockage can be reduced, thereby improving the efficiency of the peritoneal dialysis tubing 1 when performing dialysis on the patient.
