Description

Technical Field

[0001] The utility model belongs to the technical field of peritoneal dialysis, and in particular relates to a dialysis tube joint with a protective sleeve. Background Art

[0002] Peritoneal dialysis is a type of dialysis that uses the body's own peritoneum as a dialysis membrane. The dialysate infused into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum, in order to remove metabolic products and toxic substances from the body and correct water and electrolyte imbalances.

[0003] At present, dialysis is the main treatment method used by many hospitals to treat kidney diseases such as uremia and renal failure. For the convenience of operation, a catheter is generally placed in the patient's vein. A connector is provided at the end of the catheter, so there is no need to puncture the skin during each dialysis during the retention period. It is only necessary to connect the external tube to the connector of the catheter. Therefore, it has been widely used in clinical practice.

[0004] Since the external tubes and connectors are exposed to the outside after being connected, they are easily contaminated by contact during long-term use, which may cause the risk of infection. Currently, in order to keep the external connectors relatively clean and prevent infection complications, disposable gauze is often used to wrap the connectors and fix them with tape. However, the gauze is easy to slip off, and the operation process is complicated, time-consuming and labor-intensive. At the same time, nurses wear medical rubber gloves during the operation. The tape is easy to stick to the gloves during the tearing and sticking process, affecting the operation.

[0005] For this purpose, we propose a dialysis tube connector with a protective sleeve. Utility Model Content

[0006] In order to solve the technical problem that the dialysis catheter joint in the prior art is wrapped with gauze and fixed with adhesive tape, which is not only easy to slip off but also has a complicated operation process and is time-consuming and labor-intensive, the utility model provides a dialysis tube joint with a protective cover.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A dialysis tube connector with a protective cover comprises a connector body and a protective cover body, wherein the connector body comprises an indwelling tube end connector and an external tube end connector, wherein the ends of the indwelling tube end connector and the external tube end connector are respectively connected to the indwelling catheter and the external catheter, and the indwelling tube end connector and the external tube end connector are detachably connected, and the protective cover body comprises a silicone sleeve, which is arranged on the indwelling tube end connector, and the silicone sleeve is sealed to the indwelling tube end connector at one end away from the external tube end connector, and the other end is connected to a sealing component, and is detachably connected to the external tube end connector through the sealing component and sealed and tightened.

[0009] By adopting the above technical scheme, the utility model is applied to the existing dialysis treatment process, the outer end of the indwelling catheter used is connected with the indwelling tube end joint, and the end of the external catheter is connected with the external tube end joint. When treating kidney diseases such as uremia and renal failure, when the patient is dialyzed, the connection between the indwelling catheter and the external catheter is mainly to first connect the external tube end joint to the indwelling tube end joint, and then pull the rubber sleeve through the sealing component and connect the sealing component to the external tube end joint, so that the indwelling tube end joint and the external tube end joint are covered in the rubber sleeve, and the sealing and tightening are achieved. Compared with the technical means of wrapping gauze in the prior art, the utility model is simple to operate and easy to use. It does not need to be fixed with tape, and can avoid sticking to the gloves during tearing and sticking the tape and affecting the operation, which can save the nurse's time, and the connection is stable and will not slip off, which can reduce the probability of contamination at the joint, protect the patient from infection, and is conducive to use.

[0016] In a further technical solution, a sealing groove engaged with the sealing joint is provided on one side of the holding portion close to the indwelling tube end joint, and a sealing gasket is provided in the sealing groove.

[0017] By adopting the above technical solution, after the external tube end joint is connected to the sealing joint, the sealing joint is embedded in the sealing groove. The sealing groove and the sealing gasket arranged in the sealing groove effectively improve the sealing performance of the external tube end joint and the sealing joint, thereby providing a guarantee to prevent the patient from being infected.

[0018] In a further technical solution, an annular groove is provided on the outer side wall of the retention tube end joint, a clamping assembly is sleeved in the annular groove, and the silicone sleeve is clamped and fixed in the annular groove by the clamping assembly.

[0019] By adopting the above technical solution, the silicone sleeve is placed on the retention tube end joint, and a clamping assembly is used to clamp the silicone sleeve in the annular groove to prevent the silicone sleeve and the retention tube end joint from sliding, while ensuring the sealing performance.

[0020] In a further technical solution, the clamping assembly includes a clamping ring and a locking bolt. The clamping ring is symmetrically broken at one point and fastening plates are extended on both sides. Fastening threaded holes are opened on the fastening plates, and the locking bolt is threadedly connected in the fastening threaded holes.

[0021] By adopting the above technical solution, the two fastening plates are tightly connected together by tightening the locking bolt, so that the clamping ring clamps the silicone sleeve. If the silicone sleeve is damaged due to unexpected circumstances, the silicone sleeve can be replaced to avoid overall replacement and reduce costs.
