Adjustable peritoneal dialysis machine for sequential treatment and dialysis method

Abstract

The invention belongs to the technical field of dialysis, and particularly discloses an adjustable sequential treatment peritoneal dialysis machine and a dialysis method.The adjustable sequential treatment peritoneal dialysis machine comprises a plurality of fluid infusion channels, a heating module, a main controller, an electromagnetic valve driving module, a solution metering module and an electromagnetic valve set module; inlets of the plurality of fluid infusion channels are respectively connected with dialysis bags with different dialysis solution concentrations or different dialysis solution types, and outlets of the plurality of fluid infusion channels are all connected with a heating bag; the main controller is respectively connected with the electromagnetic valve driving module and the solution metering module; the solution metering module is used for respectively metering the flow of the dialysis solution flowing into the heating bag from the plurality of fluid infusion channels and sending metering data to the main controller. The concentration Cn and the use amount Vn of the dialysate for treatment are set, the main controller calculates and selects the fluid infusion channel, the fluid infusion channel is controlled to be opened and closed according to flow data fed back by the solution metering module, accurate control over the concentration and the use amount of the dialysate is achieved, and the conditions of operation errors and low configuration efficiency caused by manual operation are avoided.

Description

technical field [0001] The invention belongs to the technical field of dialysis, and in particular relates to an adjustable sequential therapy peritoneal dialysis machine and a dialysis method. Background technique [0002] Peritoneal dialysis (PD) is a dialysis method that uses the human body's own peritoneum as a dialysis membrane, referred to as peritoneal dialysis; solutes and water are removed between the dialysis solution poured into the peritoneal cavity and the plasma components in the capillaries on the other side of the peritoneum. Through the exchange of dialysis solution, the metabolites and excess water retained in the body are removed, and the necessary nutrients are supplemented by the dialysis solution; through the continuous renewal of the dialysis solution, the purpose of renal replacement or supportive treatment is achieved. [0003] The average body temperature of the human body is between 36 and 37 degrees Celsius, beyond this range is fever, below 38 de...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an adjustable sequential treatment peritoneal dialysis machine and a dialysis method to solve the problem that the current peritoneal dialysis machine needs to manually configure the concentration of the dialysis solution, which is cumbersome to operate, time-consuming and laborious, and not intelligent enough.
