Description

Technical Field

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

[0002] Peritoneal dialysis is the abbreviation of peritoneal dialysis. It uses the peritoneum as a semi-permeable membrane and gravity to infuse the prepared dialysate into the patient's peritoneal cavity through a catheter. In this way, there is a concentration gradient difference of solutes on both sides of the peritoneum. The solutes on the high-concentration side move to the low-concentration side (diffusion effect); water moves from the low-osmotic side to the high-osmotic side (osmotic effect). The peritoneal dialysis fluid is continuously replaced to achieve the purpose of removing metabolic products and toxic substances in the body and correcting water and electrolyte imbalance.

[0003] Peritoneal dialysis is also called home peritoneal dialysis, so most patients complete peritoneal dialysis at home. The operator of peritoneal dialysis can be the patient himself, or the patient's family member or nanny. For patients who do home dialysis, the peritoneal dialysis tube connected to the abdominal cavity has been inserted in advance. When doing home dialysis, first remove the tube cap of the peritoneal dialysis tube connector and the tube cap of the dialysate tube connector, and then connect the dialysate tube connector of the peritoneal dialysis fluid with the peritoneal dialysis tube connector of the abdominal cavity. The peritoneal dialysis process after connection is that the peritoneal dialysis fluid is input into the patient's abdominal cavity through the dialysate tube and the peritoneal dialysis tube, and through a layer of lining membrane on the patient's own abdominal cavity and organs, the excess fluid and waste in the patient's body penetrate from the blood into the dialysate, and then through the peritoneal dialysis tube and the dialysate tube, it is discharged from the body and discarded, and then fresh dialysate is poured into the abdominal cavity again. Repeat this 3-4 times to complete this dialysis.

[0004] When doing peritoneal dialysis at home, there is a step that requires the patient or family members to aseptically connect the peritoneal dialysis tube connected to the abdominal cavity with the dialysis tube connected to the peritoneal dialysis fluid. The problem now is that many patients who need peritoneal dialysis are elderly people with poor eyesight. When doing peritoneal dialysis alone, they cannot connect the ports for a long time because they cannot see them clearly. If the patients are impatient and directly touch them with their hands to help with the connection, the risk of bacterial infection will be greatly increased.

[0005] Therefore, how to design an auxiliary device that can help patients with poor vision to achieve aseptic docking of peritoneal dialysis tubes and dialysate tubes is a practical problem that needs to be solved urgently. Utility Model Content

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects in the prior art that, when peritoneal dialysis patients with poor eyesight perform aseptic docking of the peritoneal dialysis tube and the dialysate tube, the docking time is long because they cannot see the docking interface clearly, and the risk of bacterial infection is increased when using hand touch to assist. The present invention thus provides a docking assistance device that can assist patients with poor eyesight to achieve aseptic docking of the peritoneal dialysis tube and the dialysate tube.
