Description

Peritoneal dialysis equipment

Technical Field

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

Background

Peritoneal dialysis techniques are variations similar to artificial blood purification. This is achieved by using the patient's peritoneum, which is well supplied with blood, as the body's own filtering membrane. The dialysis fluid is fed into the abdominal cavity of the patient through a catheter, and according to the osmotic principle, the urine components are removed from the blood and enter the abdominal cavity. After several hours, the dialysate carrying the urine component is then drained from the peritoneal cavity, thereby achieving the effect of dialysis.

In the prior art, peritoneal dialysis can generally be performed using several different methods. For example, for Continuous Ambulatory Peritoneal Dialysis (CAPD), the patient himself can manually change the dialysate, e.g., 4 to 5 dialysate changes per day; for Automated Peritoneal Dialysis (APD), a device called a Cycler (Cycler) allows automatic exchange of dialysis bags at night, so that the patient is not restricted during the day.

In such automated peritoneal dialysis, the peritoneal cavity is filled with dialysate through a cycler, the fill volume needs to be controlled, and the maximum fill volume provided to the patient is, for example, about 3500ml for an average adult. Usually, a standard value is used for the filling amount, and the complicated work of determining the filling amount peculiar to each patient by experiment can be avoided.

A patient who needs to carry out peritoneal dialysis needs to put a dialysis tube into the body through a surgical operation, the mouth of the dialysis tube is positioned outside the body, the peritoneal dialysis can be carried out by butting the dialysis tube with a dialysis liquid tube of a dialysis liquid storage device, and dust and bacteria in the air easily enter the body during butting to cause infection, so that complications such as peritonitis are caused.
