Description

Aseptic connecting device for peritoneal dialysis

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a peritoneal dialysis aseptic connecting device.

Background

Peritoneal Dialysis (PD) is a type of dialysis that uses the peritoneum of the human body itself as a dialysis membrane. The dialysate filled into the abdominal cavity exchanges solute and moisture with the plasma components in the capillary vessel on the other side of the peritoneal cavity, thereby removing the metabolites and excessive moisture retained in the body, and simultaneously supplementing the substances necessary for the body through the dialysate. The aim of kidney substitution or supporting treatment is achieved by continuously updating the peritoneal dialysis solution.

In current life, a lot of patients often can carry out peritoneal dialysis by oneself at home, when patient need carry out peritoneal dialysis, then need connect peritoneal dialysis liquid pipe and external nozzle stub, specific conventional operation then mainly is: patient or patient's family members left hand are held between the fingers and are connected to the connector of the external stub pipe tip of patient's health, the right hand is held between the fingers peritoneal dialysis fluid tube head, the right hand cooperation left hand comes the iodophor cap of the connector outside the external stub pipe tip that the left hand was held between the fingers to get, the left hand cooperation right hand comes the tube cap of the peritoneal dialysis fluid tube head department that the right hand was held between the fingers to get, draw close the external stub pipe of the iodophor cap relatively again and get the peritoneal dialysis fluid tube of tube cap off, the connector that comes the external stub pipe tip is pegged graft with peritoneal dialysis fluid tube head mutually.

For the above operation, it needs to be performed under aseptic conditions, otherwise, when the connector of the external short tube of the iodophor cap is removed and/or the peritoneal dialysis solution tube head of the tube cap is contaminated, the dialysate flowing through the connector is more easily contaminated, so that peritonitis and other complications of the patient are easily caused to bring danger to the life of the patient.

The common disadvantages of the above-mentioned patients or their families are: patient or patient's family members are not professional, it is not comprehensive enough to aseptic consciousness, when its right hand cooperation left hand comes to get the outer iodophor cap of the connector of the external stub pipe tip that the left hand was held, the peritoneal dialysis tubing tube head outer wall that its right hand was held then very easily touches the connector of the external stub pipe of getting the iodophor cap, make the connector of corresponding external stub pipe can be contaminated in advance, equally, when its left hand cooperation right hand comes to get the tube cap of the peritoneal dialysis tubing tube head department that the right hand was held, the external stub pipe outer wall that its left hand was held also very easily touches the peritoneal dialysis tubing tube head of getting the tube cap, make corresponding peritoneal dialysis tubing tube head also can be contaminated in advance, and the sanitary environment in the house is relatively poor, the aseptic connection operation of relevant peritoneal dialysis is also easily contaminated by the foreign object.

Thus, the existing problems remain to be solved.
