Description

Technical Field

[0001] The utility model relates to the technical field of peritoneal dialysis, in particular to a peritoneal dialysis aseptic auxiliary device. Background Art

[0002] In recent years, the number of patients with chronic kidney disease has increased year by year, and the number of patients who choose peritoneal dialysis for renal replacement therapy has increased day by day. Peritoneal dialysis patients are mainly treated at home and need to perform 3-5 peritoneal dialysis fluid changes every day as ordered by the doctor. Each peritoneal dialysis fluid change process takes about 30 minutes, and there are certain sterile requirements for the peritoneal dialysis fluid change operation and fluid change environment. Peritoneal dialysis patients need to isolate an independent peritoneal dialysis fluid change space at home, open windows regularly for ventilation, turn on ultraviolet lamps at regular intervals every day, close doors and windows during peritoneal dialysis fluid changes to prevent dust, and pets are not allowed to enter, etc.

[0003] Peritoneal dialysis-related peritonitis is a serious complication for peritoneal dialysis patients. It not only increases the physical pain and economic burden of patients, but is also the main cause of technical failure in peritoneal dialysis patients. Therefore, ensuring safe peritoneal dialysis fluid exchange at home can effectively prevent the occurrence of peritonitis.

[0004] However, peritoneal dialysis patients are not medical professionals, and most of them are elderly. There are problems in home peritoneal dialysis treatment:

[0005] (1) Ultraviolet irradiation is commonly used for environmental air disinfection on the market, 40 minutes each time, 2 to 4 times a day, but this method is harmful to the human body, especially for elderly patients, who are prone to forget to disinfect the air, and it is difficult to implement a sterile environment for a long time. Therefore, there is a lack of an easy-to-use sterile device for peritoneal dialysis fluid exchange. (2) The peritoneal dialysis fluid tube connector in the initial state is provided with a pull ring to protect it, and the peritoneal dialysis short tube connector is provided with a threaded iodine cap to protect it. When peritoneal dialysis fluid is exchanged, the patient needs to remove the pull ring and iodine cap from the peritoneal dialysis fluid tube connector and the peritoneal dialysis short tube connector and then connect them. Especially for elderly patients or diabetic patients, because they often have poor eyesight or hand tremors, their hands can easily touch the tube mouth of the peritoneal dialysis short tube, the interface of the dialysis fluid tube connector and the edge of the iodine cap, which can easily cause the catheter mouth to be infected and It is also difficult to accurately align the tube opening of the peritoneal dialysis short tube with the interface of the dialysate tube connector, which greatly increases the chance of peritoneal infection. Therefore, there is a lack of peritoneal dialysis fluid exchange fixing devices; (3) After connecting the tube opening of the peritoneal dialysis short tube with the interface of the dialysate tube connector, some patients will ignore the small section of the connecting tube exposed to the air, especially for bedridden manual peritoneal dialysis patients and nighttime automated peritoneal dialysis patients. The exposed section of the peritoneal dialysis connector is in contact with the bed unit for a long time, increasing the risk of contamination. Some patients will also use the peritoneal dialysis outer packaging bag or the unsealed iodine cap outer packaging to partially cover it. These treatment methods are not only inconvenient, but also have the risk of secondary contamination. They are also not conducive to observing whether the connection port is loose or slipped. Moreover, the connection is free and not fixed outside, and the catheter often shakes, greatly increasing the risk of dust and bacteria in the air entering. Therefore, there is a lack of sterile devices for peritoneal dialysis fluid exchange to prevent the tube from falling off.

[0006] In summary, there are various forms of peritoneal dialysis related devices on the market, but no device can simultaneously solve the three problems of preventing the tube from falling off, fixation, and sterility during peritoneal dialysis fluid exchange. Utility Model Content

[0014] The fixing strip hook surface of the inlet fixing strip matches with the sealing strip rough surface and adheres to each other, so as to fit and penetrate the peritoneal dialysis tube when the peritoneal dialysis tube inlet port connection pad and the peritoneal dialysis tube inlet port bottom pad are closed.

[0015] The fixing strip hook surface of the outlet pipe fixing strip matches the rough surface of the sealing strip and is bonded to each other so as to fit and penetrate the external short pipe when the outlet port pad and the outlet port bottom pad are closed.

[0016] The area of ​​the docking sterile bottom surface is the same as the area of ​​the docking sterile top surface.
