Embodiment Construction

[0039] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0040] For the precision hemodialysis system provided in this embodiment, see figure 1 and figure 2 As shown, the dialysis system includes a dialysate preparation and supply device 100 for preparing dialysate and a dialysis machine 200 connected to the dialysate preparation and supply device 100 through pipelines. It should be noted that the dialysate liquid preparation and supply device 100 for the dialysate system is used to connect with the dialysis machine through pipelines, that is, the dialysate provided by the dialysate liquid preparation and supply device 100 for the dialysate system It is directly used in the dialysis work of the dialysis machine.

[0041] The dialysate liquid preparation and supply device 100 includes a dosing mechanism. The dosing mechanism mixes multiple or all raw material components in the raw materials used in...

Abstract

The invention relates to a precise hemodialysis system which comprises a dialysate preparing and supplying device and a dialysis machine, the device comprises a preparing mechanism, and the preparing mechanism is used for independently mixing multiple or all raw material components in raw materials used for dialysate with water to prepare saturated solutions corresponding to the raw material components; the preparing mechanism comprises a plurality of preparing units which are arranged in parallel and are respectively used for preparing saturated solutions of corresponding raw material components and liquid conveying pipelines which are respectively connected with the preparing units, flow meters are respectively arranged on liquid conveying pipes which are respectively connected with the preparing units in the liquid conveying pipelines, and the device further comprises control units which are respectively and electrically connected with the flow meters. By utilizing the characteristic that the saturated solution of each raw material is a fixed value, the outflow rate of the saturated solution of each raw material is regulated and controlled, and the preparation dosage of each raw material component can be accurately controlled, so that the aim of accurately preparing the dialysate meeting the treatment requirement is fulfilled, intermediate links are effectively reduced, and new pollution risks are not introduced from the raw materials to the dialysis machine.

Description

technical field [0001] The invention belongs to the technical field of medical device manufacturing, and in particular relates to a precision hemodialysis system. Background technique [0002] Hemodialysis is mainly used to treat diseases such as chronic renal failure, acute renal failure and drug poisoning, and has been widely used clinically. Hemodialysis uses the principle of semi-permeable membrane to introduce the patient's blood and dialysate into the hemodialyzer at the same time, and flows in opposite directions on both sides of the dialysis membrane, relying on the solubility gradient, osmotic gradient and water pressure gradient on both sides of the semi-permeable membrane. Remove toxins through diffusion, convection, and adsorption; remove excess water in the body through ultrafiltration and osmosis; at the same time, replenish the required substances and correct electrolyte and acid-base balance disorders. [0003] During the hemodialysis process, the dialysis m...
