Liquid-supplying system of hemodialysis center

Abstract

The invention relates to a liquid-supplying system of a hemodialysis center, which supplies medicinal liquid A and B to a hemodialysis machine. The liquid-supplying system of the hemodialysis center comprises a liquid-absorption conveying device, a liquid-storing device, liquid-supplying devices, and associated pipelines, valves and control circuits, wherein the liquid-absorption conveying device is communicated with the liquid-storing device through the associated pipeline, pump, valve and plug; the liquid-storing device is communicated with the liquid-supplying device A through the associated pipeline, pump and valve; the liquid-supplying device A is communicated with the hemodialysis machine; the liquid-supplying device B is communicated with the hemodialysis machine; the liquid A supplying mode is diverse, and the formula of the liquid A is adjusted at any time according to the different requirements of patients and advice of doctors so as to achieve the best therapeutic effect; pure water is heated by a thermostatic water feeder and enters the liquid-supplying device B to mix with powder B such that the mixture can be used at once without stirring, the dialysis effect of carbonic acid can be ensured and the raw materials are not wasted; the liquid is completely separated from air so as to effectively prevent the growth of bacteria and the generation of biomembrane on the inner wall of the liquid-supplying pipes; and the liquid-supplying system is time-saving, labor-saving, liquid-saving, sanitary, safe and reliable, and has simple operation and no pollution.

Description

Technical field [0001] The invention belongs to the field of medical hemodialysis and relates to a medical hemodialysis center liquid supply system. Background technique [0002] The existing hemodialysis liquid supply system has an unreasonable design of the liquid supply method. Liquid A is generally acidic, and the liquid supply method is single, which makes it difficult to adjust the pressure of the liquid. Liquid B is a sodium bicarbonate solution and is used for pipeline delivery. Liquid, the pipeline has a blind end, the flow is slow, or even static, the storage liquid is not completely separated from the air, which cannot effectively prevent the growth of bacteria and the production of biofilm on the inner wall of the liquid supply pipeline; the chemical disinfection of the liquid supply pipeline is particularly troublesome and time-consuming , Laborious, liquid waste, environmental pollution, easy to cause adverse effects on dialysis patients. Summary of the invention ...

Problems solved by technology

[0002] The existing liquid supply system for hemodialysis has an unreasonable design of the liquid supply method. Liquid A is common, which is acidic, and the liquid supply method is single, so it is difficult to adjust the pressure of the liquid supply; The pipeline has blind ends, the flow is slow, or even static, and the storage fluid is not completely separated from the air, which cannot effectively prevent the growth of bacteria and the generation of biofilm on the inner wall of the supply pipeline; the chemical disinfection of the supply pipeline is particularly cumbersome and time-consuming , laborious, waste liquid, pollute the environment, and easily cause adverse effects on dialysis patients
