Problems solved by technology

[0002] In the past, the hemodialysis concentrate was prepared manually and stored in plastic barrels; in this way, it was impossible to realize the centralized supply of the concentrate, and it was also impossible to realize online cleaning and disinfection; it was a waste of man-hours and could not meet the hygienic needs
The inner surface of the pipeline connection is not smooth, resulting in unclean cleaning and dirt, which is not conducive to the cleanliness of the dosing solution and affects the quality of the dosing solution; in addition, frequent manual operations increase the chance of contamination and the risk of quality problems
In the past, A and B concentrate filters used a simple Buchner funnel, which was inconvenient to operate and could not be cleaned and disinfected online, which brought cleanliness and sanitation problems

Abstract

The invention discloses a hemodialysis agent liquid preparation and centralized supply system comprising two sets of liquid preparation systems. More specifically, each set of liquid preparation system comprises a liquid preparation tank, a liquid preparation tank, a hygiene-grade delivery pump, a microporous membrane filter and a pipe distribution system, wherein the liquid preparation tank is connected to the liquid preparation tank. Liquid is delivered by the hygiene-grade delivery pumps, filtered by the microporous membrane filters and subsequently distributed and supplied by the pipe distribution systems. The liquid contains a concentrated liquid A and a concentrated liquid B that are mixed in a ratio of 1: 1 and then charged into a hemodialysis unit, wherein the concentrated liquid A is mainly prepared from an aqueous solution of sodium chloride, potassium chloride, calcium chloride, magnesium chloride and acetic acid, and the concentrated liquid B is mainly prepared from an aqueous solution of sodium bicarbonate or sodium bicarbonate and sodium chloride.

Description

technical field [0001] The invention relates to a centralized supply system for hemodialysis agent preparation and belongs to the technical field of medical product processing. Background technique [0002] In the past, the hemodialysis concentrate was prepared manually and stored in plastic barrels; in this way, it was impossible to realize the concentrated supply of the concentrate, and it was also impossible to realize online cleaning and disinfection; it was a waste of man-hours and could not meet the hygienic needs. The inner surface of the pipeline connection is not smooth, resulting in unclean cleaning and dirt, which is not conducive to the cleanliness of the dosing solution and affects the quality of the dosing solution; in addition, frequent manual operations increase the chance of contamination and the risk of quality problems. In the past, the A and B concentrate filters used a simple Buchner funnel, which was inconvenient to operate and could not be cleaned and ...
