Method for stabilizing dialysate consumption flow, corresponding apparatus and central dialysate preparation and distribution system

Abstract

A method for stabilizing dialysate consumption flow in a central distribution loop (21) for a plurality of dialysis machines (3) comprises steps as follows: coordinating each dialysate dispensing cycle of active ones of the dialysis machines (3); calculating dialysate or concentrates consumption based on amount required in each dialysate dispensing cycle of the active dialysis machines (3); and preparing the dialysate based on the calculated dialysate or concentrates consumption required by the active dialysis machines (3). A corresponding apparatus (4) and a corresponding central dialysate preparation and distribution system are further disclosed. The apparatus at least comprises: a coordinating module (41) configured to coordinate each dialysate dispensing cycle of active ones of the dialysis machines (3); a calculating module (42) configured to calculate dialysate or concentrates consumption based on amount required in each dialysate dispensing cycle of the active dialysis machines (3); and a mixing control module (43), for preparing the dialysate based on the calculated dialysate or concentrates consumption. According to the present invention, the dialysate consumption flow can be stabilized such that a simple structure, lower cost, a compact design and more accurate dialysate preparation can be achieved.

Description

technical field [0001] The invention relates to a method for stabilizing a dialysate consumption flow in a central distribution circuit for several dialysis machines, a device for stabilizing a dialysate consumption flow and a central dialysate fluid for carrying out the method Prepare the dispensing system. Background technique [0002] Hemodialysis is a procedure used to remove toxic substances and metabolites that would normally be removed by the kidneys and to help regulate fluid and electrolyte balance in the body. Hemodialysis is usually done using dialysate through a dialysis machine. [0003] Currently, a central dialysate preparation and distribution system is widely used to prepare dialysate and distribute the prepared dialysate to a plurality of dialysis machines, for example about 30-40 dialysis machines. [0004] Some components of the central dialysate preparation and distribution system are usually installed in an isolated room some distance from the treatme...
