[0002] Peritoneal dialysis is a kind of dialysis mode using human body's peritoneum as dialysis membrane. It removes metabolic waste and excess water in the body by filling and discharging dialysis fluid to achieve the effect of treating kidney. Peritoneal dialysis is mainly used for treating end-stage renal disease or acute kidney injury patients to help or replace part or all of the kidney function.

[0003] Generally, the external connecting short pipe is connected with one end of the peritoneal dialysis catheter through a joint, the other end of the peritoneal dialysis catheter is arranged in the abdominal cavity, the external connecting short pipe connects two bifurcated liquid channels, one of which is connected with fresh dialysate, and the other is connected with a waste liquid bag for containing waste obtained by dialysis. During peritoneal dialysis, dialysate is injected into the peritoneal dialysis catheter through the external connecting short pipe, and then enters the abdominal cavity. The dialysate uses the peritoneum as a natural semi-permeable membrane, and through the diffusion and ultrafiltration effect, the waste and excess water enter the dialysate, so as to be discharged to the waste bag with the dialysate, thereby completing a dialysate exchange.

[0019] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] This embodiment discloses a disinfection device for replacing peritoneal dialysis external catheters, enabling the replacement of external catheters of different specifications, reducing the risk of infection, improving patient comfort, and reducing the workload of medical staff.

[0021] See Figures 1 to 4 As shown, the disinfection device for replacing the peritoneal dialysis external catheter in this embodiment includes a disinfection container 1 and a clamping structure 2. The disinfection container 1 is used to soak the connector of the external catheter, and the edge of the disinfection container is rolled up to be clamped by the clamping structure 2. In this embodiment, the disinfectant used to soak the external catheter is preferably a special disinfectant such as povidone-iodine.

[0022] The clamping structure 2 includes a first clamping member 21 and a second clamping member 22. Both the first clamping member 21 and the second clamping member 22 are U-shaped structures. The first clamping member 21 is disposed above the second clamping member 22. The U-shaped structure of the first clamping member 21 forms a pipe clamping area 211 for clamping the two bifurcated ends of the external short pipe. The U-shaped structure of the second clamping member 22 forms a fixing area 221 for detachable / clamping the edge of the sterilization container. The opening end of the pipe clamping area 211 faces the first direction, and the opening end of the fixing area 221 faces the second direction. The first direction and the second direction are perpendicular to each other.

[0023] Compared with existing technologies, the innovative disinfection device for replacing peritoneal dialysis external catheters proposed in this invention consists of a disinfection container 1 and a clamping structure 2. The disinfection container 1 is used to hold disinfectant solution, which is used to thoroughly wet the connector and part of the external catheter at the connector. Deep disinfection is achieved through immersion, thereby effectively killing any microorganisms that may be present, which helps prevent cross-infection and protects the health and safety of patients.

[0024] The clamping structure 2 is composed of a first clamping member 21 and a second clamping member 22. The first clamping member 21 is positioned on top of the second clamping member 22, and the second clamping member 22 is used to engage the rolled-up edge of the sterilization container 1. In actual use, the number of clamping structures 2 is selected and set according to the portion of the external short tube to be soaked. In this embodiment, the portion to be soaked is the interface of the external short tube connecting the new dialysate bag and the waste bag. The soaking method involves clamping the branches of the two external short tubes leading to the dialysate bag and the waste bag with the first clamping member 21, and then immersing the interface connected to the peritoneal dialysis catheter downwards into the sterilization container 1 to achieve soaking. Since the soaking time for sterilization is usually relatively long (usually ten minutes), it often requires the patient / medical staff to hold the container, which requires waiting. When medical staff are busy or patients are unable to hold the sterilization container 1 and the external short tube for a long time, this sterilization device can free up their hands and avoid contamination of the soaked external short tube due to negligence during the holding process.

[0025] In summary, the disinfection device for replacing the peritoneal dialysis external catheter in this embodiment takes into account hygiene and safety factors during the disinfection process. It can avoid patients repeatedly coming into contact with the external catheter and disinfectant when replacing the external catheter, reducing the risk of cross-infection, further reducing the probability of infection caused by improper operation, and at the same time reducing the workload of medical staff and improving the comfort of patients during the replacement process.

[0026] See Figure 3 and Figure 4 As shown, the first clamping member 21 is further provided with a pressing member 212 for pressing against the external short pipe. The pressing member 212 passes through the top of the first clamping member 21 and is connected to a pad 213. In this embodiment, the pressing member 212 is a threaded rod that can be slidably fixed on the top of the first clamping member 21. The pressing member 212 is used to restrict and fix the external short pipe in the pipe clamping area 211, ensuring the stability of the external short pipe. The pad 213 can be a silicone structure or a magnet. The pad 213 is used to contact the external short pipe to increase the contact area, improve the clamping strength, and stabilize the pressing member 212, preventing the pressing member 212 from shaking. The pressing member 212 and the pad 213 further ensure the stability of the external short pipe clamping.

[0027] See Figure 3 and Figure 4 As shown, the second clamping member 22 also has a protrusion 222, which is used to elastically press against the edge of the sterilization container 1. The protrusion 222 has an elastic structure and is used to enhance the stability of the engagement between the second clamping member 22 and the edge of the sterilization container 1. In this embodiment, the protrusion 222 and the main body of the second clamping member 22 are integrally formed. The protrusion 222 has a wave structure and is preferably made of slightly deformable silicone. The protrusion 222 helps the second clamping member 22 to be stably engaged with the edge of the sterilization container 1, preventing the first clamping member 21 and the second clamping member 22 from falling into the sterilization container 1.

[0028] See Figure 1 and Figure 2 As shown, the disinfection container 1 has a frustum-shaped structure. In this embodiment, the diameter of the top opening of the disinfection container 1 is larger than the diameter of the inner bottom, and the frustum-shaped disinfection container 1 has an immersion depth, which helps to fully immerse the outer connecting pipe.

[0029] See again Figure 3 and Figure 4 As shown, the inner sidewalls 21A and 22A of the first clamping member 21 and the second clamping member 22 are both arc-shaped. The arc-shaped structure helps to make the first clamping member 21 and the second clamping member 22 more compatible with the edge of the external short tube or disinfection container 1 being clamped.

[0030] Optionally, the open end B of the clamping area 211 is inclined. The inclined structure facilitates the insertion of the external short pipe.

[0031] Optionally, the first clamping member 21 and the second clamping member 22 are integrally formed, and the material of the first clamping member 21 and the second clamping member 22 is preferably a slightly deformable silicone structure. The deformable silicone structure prevents the first clamping member 21 and the second clamping member 22 from breaking due to collision or jamming during the engagement process, thus avoiding affecting the use and preventing them from falling into the sterilization container 1, causing contamination, and affecting the safety of use.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Meanwhile, the above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
