Description

Technical Field

[0001] This utility model relates to the field of peritoneal dialysis external catheter disinfection technology, and in particular to a peritoneal dialysis external catheter disinfection device that is easy to replace. Background Technology

[0002] Peritoneal dialysis catheters are the "lifeline" for peritoneal dialysis patients. The extraperitoneal segment of the peritoneal dialysis catheter is connected to the peritoneal dialysis fluid via a connecting tube, also known as the external short tube. This external short tube is the part outside the body. Due to the frequent opening of the iodine cap for peritoneal dialysis operations and frequent contact with disinfectants, there is a risk of aging and infection. Therefore, regular replacement of the external short tube is of great significance for preventing infection and ensuring dialysis effectiveness.

[0003] Current dressing change techniques do not have a specially designed disposable dressing change kit for peritoneal dialysis patients with external short tubes. In addition, the disinfectant bottles used to soak the external short tubes of peritoneal dialysis are not standardized among hospitals, and the size of the disinfectant bottle directly affects the length of the external short tube to be soaked.

[0004] To address the aforementioned issues, this utility model proposes a peritoneal dialysis external short tube sterilization device that is easy to replace. Utility Model Content

[0005] This invention provides a peritoneal dialysis external catheter disinfection device that is easy to replace, which solves the shortcomings of the prior art, such as the lack of a disposable dressing pack specifically designed for changing the dressing of the external catheter for peritoneal dialysis patients, and the inconsistent use of disinfectant bottles for soaking the external catheter in different hospitals, with the capitalization of the disinfectant bottle directly affecting the length of the external catheter to be soaked.

[0006] This utility model provides the following technical solution:

[0007] A peritoneal dialysis external cannula sterilization device that is easy to replace, comprising:

[0008] A disinfectant container, wherein the disinfectant container is used to fill liquid disinfectant, and a flexible bottle opening is connected to the center of the top of the disinfectant container. A peritoneal osmosis tube is inserted into the flexible bottle opening, and a matching titanium connector is provided at the bottom end of the peritoneal osmosis tube.

[0009] The sealing assembly, located on the flexible bottle opening, is used to secure the peritoneal dialysis tubing to prevent the liquid disinfectant level from exceeding the titanium connector and corroding the peritoneal dialysis tubing.

[0010] In one possible design, the necking assembly includes a hollow ring fixedly disposed at the top of the flexible bottle neck, a drawstring passing through the hollow ring, and both ends of the drawstring passing through the outlet of the hollow ring and slidably connected to the same tightening block.

[0011] In one possible design, both ends of the drawstring are fixedly provided with flat blocks to prevent the tightening block from detaching.

[0012] In one possible design, the upper edges of both sides of the outer wall of the disinfectant container are provided with scale lines to facilitate the determination of the liquid disinfectant level.

[0013] In one possible design, the tightening block is provided with anti-slip textures to increase friction.

[0014] In one possible design, the disinfectant container is a sterile, disposable medical product.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] When using, check whether the disinfectant container is intact, confirm that the liquid disinfectant is filled to a sufficient level, and that the scale lines are clearly visible. Then, slowly insert the titanium connector end of the peritoneal dialysis tubing into the disinfectant container through the soft bottle opening, ensuring that the titanium connector is completely immersed in the liquid disinfectant. Adjust the liquid level of the liquid disinfectant according to the scale lines, ensuring that the liquid level does not exceed the titanium connector to prevent corrosion of the peritoneal dialysis tubing. Pull the drawstring in the closing assembly to tighten the drawstring in the hollow ring, and secure the peritoneal dialysis tubing by tightening the tightening block or by tying the drawstring.

[0018] Place the disinfection device in a stable and safe location, ensuring that the liquid disinfectant fully soaks the titanium connector. According to the hospital or medical guidelines, wait for the prescribed disinfection time (usually 20 minutes) to allow the titanium connector to be fully disinfected. After disinfection, medical staff should loosen the tightening block, remove the peritoneal dialysis tubing, and perform subsequent connection or use operations. Since the disinfectant container is a sterile, disposable medical product, it should be disposed of in accordance with medical waste disposal regulations after use to avoid cross-infection.

[0019] This utility model has the following beneficial effects:

[0020] This utility model is designed as a special device for disinfecting the external short tubing of peritoneal dialysis. The device allows the patient to clearly see the length of the disinfection tubing, avoiding exceeding the titanium connector and corroding the peritoneal dialysis tubing. Furthermore, the standardized design of the disinfectant container and the graduation markings ensure the accuracy and consistency of each disinfection.

[0021] Furthermore, it solves the current inconvenience of patients having to hold the sterilization bottle while sitting or support the dressing bowl while lying down, allowing patients of all types to have their dressings changed conveniently in various positions.

[0022] This invention can be used to build a disposable external short tube-specific dressing change kit, making the dressing change process both convenient and professional. In addition, the disinfection device can be fixed at the soaking end, saving patients 20 minutes of holding the disinfectant container. Attached Figure Description
