Simple automatic peritoneal dialysis equipment

Abstract

The invention relates to medical equipment, in particular to simple automatic peritoneal dialysis equipment. The equipment comprises a raw water filter, an EDI electric deionizater and a raw water processing device composed of I and II class reverse osmosis units, a peritoneal dialysis liquid confecting device composed of a dual-cavity proportioning pump, a peritoneal dialysis liquid confecting three-way solenoid valve and a peritoneal dialysis liquid container, a peritoneal dialysis treating device composed of a peritoneal dialysis treating three-way solenoid valve, an abdominal cavity inner guide coupling, a waste liquid container and a negative pressure pump as well as an automatic control system composed of an ARM singlechip which carries out finishing and programming on the collected signal; wherein the signal input interface of the ARM singlechip is respectively connected with the raw water processing program module, a treating program module, a correction treating program module and a safe monitoring program module, and the signal output interface thereof is connected with a power driver which controls the external parts under the instruction of the ARM singlechip. The invention integrates water treatment, peritoneal dialysis liquid confecting and automatic peritoneal dialysis treatment, totally closed type one machine treatment is realized, and treating expense can be greatly reduced.

Description

technical field [0001] The invention relates to medical equipment, in particular to a simple automatic peritoneal dialysis equipment. Background technique [0002] Currently, peritoneal dialysis is a common method of replacement therapy for uremia. Including: (1) CAPD-continuous ambulatory peritoneal dialysis, which is a method in which patients can self-dialyze without equipment. In this method, a section of dialysis tubing is permanently placed in the abdominal cavity through minor surgery, with one end opening on the abdominal wall. During dialysis, hang a soft package bag containing 2 liters of dialysate at 1 meter above the body (supine), and the dialysate is injected into the abdominal cavity through the interface of the dialysis tube by gravity, and after 4-6 hours, the fluid in the abdominal cavity is drained out. in vitro. Repeat once a day in the morning, noon, afternoon and evening. At present, the peritoneal dialysis tube, peritoneal dialysis solution, and pi...
