Description

Peritoneal dialysis external device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an external device for peritoneal dialysis.

Background

The peritoneal dialysis extension tube, as the name suggests, is a connecting tube for connecting the peritoneal dialysis tube and the peritoneal dialysis catheter, one end of which is provided with a titanium joint for connecting the peritoneal dialysis tube, and the other end is provided with a threaded joint for connecting the peritoneal dialysis catheter. The connecting end of the corresponding peritoneal dialysis catheter is provided with a screw hole matched with the corresponding screwed joint, and the tail end of the peritoneal dialysis catheter is connected with a drainage bag for guiding the liquid.

For the peritoneal dialysis patients who are in home rest, on duty or on a trip, peritoneal dialysis liquid change needs to be carried out 3 to 4 times every day, the iodophor cap on the peritoneal dialysis external pipe joint needs to be opened when the peritoneal dialysis liquid is changed every time, so that the peritoneal dialysis external pipe is connected with the peritoneal dialysis liquid guide pipe to lead out the peritoneal liquid in the peritoneal cavity of the peritoneal dialysis patients, after the peritoneal liquid is led out, fresh peritoneal liquid needs to be filled into the peritoneal cavity of the peritoneal dialysis patients to carry out liquid exchange, the peritoneal liquid needs to be separated from the peritoneal liquid guide pipe after being filled into the peritoneal cavity of the peritoneal dialysis patients, the peritoneal dialysis external pipe joint needs to be sealed by the iodophor cap to keep airtight and sterile, and the dialysis treatment is carried out on the peritoneal dialysis patients in such a circulation manner.
