Background

Hemodialysis is mainly used for treating diseases such as chronic renal failure, acute renal failure, drug poisoning and the like, and is widely applied clinically. Hemodialysis utilizes the principle of a semipermeable membrane to introduce blood and dialysate of a patient into a hemodialyzer at the same time, flows in opposite directions on two sides of the dialysis membrane, and depends on the solubility gradient, the osmotic gradient and the water pressure gradient on two sides of the semipermeable membrane. Removing toxins by dispersion, convection and adsorption; removing excessive water in vivo by ultrafiltration and osmosis; meanwhile, the required substances are supplemented, and electrolyte and acid-base balance disorder is corrected.

In the hemodialysis process, the dialysis machine has the functions of preparing dialysate, pumping blood and dialysate to the dialyzer, providing accurate ultrafiltration control, controlling the blood, dialysate flow and transmembrane pressure in the hemodialysis process, controlling the treatment parameters of patient diafiltration in the treatment process, and finishing dialysis treatment.

The dialysate used for hemodialysis mainly contains sodium chloride, potassium chloride, calcium chloride, magnesium chloride, sodium bicarbonate, citric acid or acetic acid.

The existing dialysate supply mode is that a dialysate manufacturer uses the raw materials to mix the raw materials into dry powder or saturated solution to supply the dry powder or the saturated solution to a dialysis center in consideration of transportation and storage cost, and sodium bicarbonate and other components react and crystallize. The sodium bicarbonate solution may grow bacteria, the liquid supply mode at present is a mode of separating the sodium bicarbonate from other components into A, B components, and A, B is provided with solution and dry powder, hospitals need to configure the dry powder into concentrated solution, then supply the A/B concentrated solution to a dialysis machine for use, and the dialysis machine dilutes and mixes the A/B components on line according to the proportion provided by the concentrate to the solution which permeates blood and the like, and then supplies the solution to patients for use.

The liquid supply mode undoubtedly increases the design and development difficulty of the dialysis machine, the dialysate is diluted on line, the internal large space of the dialysis machine needs to be occupied, the whole dilution process must be accurately regulated and controlled, and excessive fluctuation cannot occur in the dialysis process.

Secondly, a part of the used raw materials is hydrate, and the proportioning accuracy is influenced by the increase and decrease of the water content in the storage and configuration processes. The prepared product needs to be transported to a treatment center, the unit mass is large, and the storage and transportation cost is high. In the dialysis center, medical care is needed to prepare the concentrated powder into concentrated solution again, and then the concentrated solution is prepared into diluent by a dialysis machine for use by a patient.
