Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a peritoneal dialysis catheter connector fixator. Background Technology

[0002] Peritoneal dialysis, as an important form of renal replacement therapy, is widely used in the treatment of patients with renal failure. In the peritoneal dialysis system, the peritoneal dialysis catheter is a key component, responsible for transporting dialysate between the peritoneal cavity and the outside world. The part of the peritoneal dialysis catheter outside the body is connected to a short tube through a dialysis catheter connector. The dialysis catheter connector is usually made of titanium. The presence of the short tube is equivalent to adding a protective barrier between the peritoneal dialysis catheter and the external environment, thus playing a very important role in peritoneal dialysis.

[0003] Currently, the dialysis tubing connector and the short tube connector are connected by threads. During use, the short tube may be pulled or accidentally bumped, and the connection between the dialysis tubing connector and the short tube connector may be bent or loosened and fall off. At the same time, the dialysis tubing connector is relatively rigid, while the dialysis tubing and the short tube are relatively soft. When fixed in the abdomen, the connection between the dialysis tubing and the dialysis tubing connector, as well as the connection between the short tube connector and the short tube, is prone to kinking, which may cause the dialysis tubing or the short tube to leak.

[0004] Therefore, in response to the above problems, we propose a peritoneal dialysis catheter connector fixator. Utility Model Content

[0005] This utility model provides a peritoneal dialysis catheter connector fixator to solve the aforementioned technical problems.

[0006] The present invention adopts the following technical solution: it includes a protective body and a fixing component. The protective body is used to protect the connection between the dialysis tube connector and the short tube connector by sleeve. The protective body includes two protective components. When the two protective components are fitted together, a protective cavity is formed to wrap the connection between the dialysis tube connector and the short tube connector. The fixing component is set outside the protective body and is used to fix the two protective components in the fitted state, thereby fixing the dialysis tube and the short tube.

[0007] Furthermore, the protective component includes a first wrapping part and a second wrapping part, wherein the second wrapping part is movably connected to one end of the first wrapping part via a first flexible part.

[0008] Furthermore, a first sealing element is provided on the surface where the two wrapping parts 1 and 2 are in contact, and the first sealing element is used to seal the connection between the two wrapping parts 1 and 2.

[0009] Furthermore, a second sealing element is provided between the first wrapping part and the second wrapping part, which is used to seal the connection between the first wrapping part and the second wrapping part.

[0010] Furthermore, one side of each of the two wrapping parts is movably connected by a flexible part.

[0011] Furthermore, protective pads are provided on the ends of the wrapping part one and the wrapping part two that are far apart from each other.

[0012] Furthermore, the fastener includes a strap disposed on one of the wrapping parts 1 and 2, the two ends of which are connected to the other wrapping parts 1 and 2 via connectors.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] In this invention, two protective components are used to wrap the connection between the dialysis tube connector on the peritoneal dialysis catheter and the connector on the short tube, and the two protective components are fixed together by a fastener, thereby strengthening the connection between the dialysis tube connector on the dialysis catheter and the connector on the short tube, reducing bending or loosening and falling off due to pulling or accidental contact, and also reducing water leakage caused by bending of the dialysis catheter and the short tube.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] This utility model provides a peritoneal dialysis catheter connector fixator, including a protective body that is sleeved on the connection between the dialysis catheter connector and the short tube connector to protect the connection. The protective body includes two protective components 1. In use, the connection between the dialysis catheter connector and the short tube connector is placed between the two protective components 1. Both protective components 1 are transparent, making it easy to observe the connection between the dialysis catheter connector and the short tube connector. When the two protective components 1 are in contact with each other, the connection between the dialysis catheter connector and the short tube connector is wrapped in the protective cavity formed between the two protective components 1. The two protective components 1 in the contact state are fixed by a fixing member set on the outside of the protective body. The dialysis tubing and the short tube are fixed in two protective components 1. Both the dialysis tubing connector and the short tube connector can fit into the protective cavity. Due to the irregularities on the dialysis tubing connector and the short tube connector, they will not separate when subjected to external pulling or accidental contact. At the same time, the protective body can also extend to the outside of the dialysis tubing and the short tube during actual use. Since the dialysis tubing connector is usually made of titanium metal and the short tube connector is usually made of hard materials such as plastic, the protective body can prevent bending at the connection between the dialysis tubing and the dialysis tubing connector, and at the connection between the short tube and the short tube connector, thus preventing leakage of the dialysis tubing or the short tube and extending the service life of the dialysis tubing and the short tube.

[0027] Preferably, for flexible use of the protective component 1, the protective component 1 includes a first wrapping part 11 and a second wrapping part 12. The second wrapping part 12 is movably connected to one end of the first wrapping part 11 via a flexible part 5 made of materials such as rubber and silicone. Since the short tube is exposed to the external environment and in contact with the dialysate for a long time, bacteria will gradually accumulate on its surface. Furthermore, due to prolonged use, the joint of the short tube may deform to a certain extent, leading to loosening of the connection and leakage. The dialysate tube joint is generally made of titanium metal, which can be disinfected and reused. Therefore, the short tube can be replaced. For example, the dialysate tube joint is fixed inside the first wrapping part 11, while the short tube joint is fixed inside the second wrapping part 12. The two wrapping parts 11 can be retained to fix the dialysate tube joint, while the flexible part 5 deforms to open the two wrapping parts 22, exposing the short tube joint for direct replacement. This avoids unnecessary disturbance to other parts of the entire system, reduces the risk of damage to other components due to improper operation, and improves the convenience of operation.

[0028] Preferably, to improve sealing, a first sealing element 3 is provided on the surface where the two wrapping parts 11 and 2 wrapping parts 12 are in contact. The first sealing element 3 may include a first sealing strip 31 and a first sealing groove 32 adapted to the first sealing strip 31. The first sealing strip 31 may be made of rubber, silicone or other materials. The first sealing strip 31 may be placed on one of the wrapping parts 11 and 2 wrapping parts 12, while the first sealing groove 32 may be placed on the other wrapping part 11 and 2 wrapping parts 12. When the two wrapping parts 11 and 2 wrapping parts 12 are in contact with each other, the first sealing strip 31 is inserted into the first sealing groove 32, sealing the inside of the protective body. This prevents deformation of the joint of the short tube due to improper connection or possible long-term use, and minimizes the entry of external dust, bacteria and other contaminants into the protective body. This further protects the short tube joint and dialysis tube, providing a more reliable guarantee for the patient's dialysis treatment.

[0029] Preferably, to improve the sealing between the first packaging part 11 and the second packaging part 12, a second sealing element 4 is provided between the first packaging part 11 and the second packaging part 12. The second sealing element 4 may include a second sealing strip 41 and a second sealing groove 42 adapted to the second sealing strip 41. The second sealing strip 41 may be made of rubber, silicone or other materials. The second sealing strip 41 may be set at one end of the first packaging part 11, and the corresponding second sealing groove 42 may be set on the side of the second packaging part opposite to the first packaging part 11. When the first packaging part 11 and the second packaging part 12 are in a straight line, the second sealing strip 41 is inserted into the second sealing groove 42, thereby sealing the first packaging part 11 and the second packaging part 12 and further enhancing the sealing effect.

[0030] Preferably, in order to improve the overall integrity of the protective body, the two wrapping parts 11 are movably connected by a flexible part 2 6 made of materials such as rubber and silicone. The flexible part 2 6 connects the two wrapping parts 11 into a whole, so that when the protective body is subjected to external force, stress can be better dispersed, avoiding structural damage due to local stress, while not affecting the independent use of the wrapping part 2 12.

[0031] Preferably, in order to reduce frictional damage to the dialysis tubing and the short tube, protective pads 7 are provided on the ends of the wrapping part 11 and the wrapping part 12 that are far apart from each other. The protective pads 7 can be made of rubber, silicone or other materials. When the connection part of the dialysis tubing connector and the short tube connector is located inside the protective body, the two ends that are in contact with the protective component 1 are the dialysis tubing and the short tube, respectively. During use, the dialysis tubing and the short tube will inevitably shake. During the shaking process, the protective pads 7 can reduce the friction between the dialysis tubing and the short tube and the protective component 1, thereby reducing damage to the dialysis tubing and the short tube.

[0032] Preferably, in order to fix the two protective components 1 together, the fixing component includes a strap 2 provided on one of the wrapping parts 11 and 12, and a connector 8 is provided between the two ends of the strap 2 and the other wrapping parts 11 and 12. The connector 8 can be a Velcro, snap fastener or other structure. When the two protective components 1 are attached, the strap 2 on one of the wrapping parts 11 and 12 is wrapped around the wrapping parts 11 and 12 in the opposite position, and then connected and fixed by the connector 8.

[0033] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
