Process and apparatus for repeated use of dialysis device

Abstract

The invention discloses a dialyzer multiplying method, which comprises the following parts: multiplying channel, pipe, cleaning liquid container, negative pressure pump, negative pressure meter, positive pressure pump and positive pressure meter. The working flow path comprises the following steps: (1) washing; (2) proceeding double-pressure cleaning; (3) washing; (4) gauging pressure; (5) detecting bulk; (6) sterilizing dialyzer.

Description

technical field [0001] The invention provides a hemodialyzer method and its equipment, in particular to a dialyzer reuse process and its equipment. technical background [0002] For patients with renal failure, hemodialysis is the main treatment. Hemodialysis is to introduce the patient's blood and dialysate into the dialyzer in opposite directions at the same time, and flow through the two sides of the dialysis membrane respectively. The solute and water on both sides move across the membrane under the concentration and pressure gradient to exchange substances. Metabolically accumulated urea, creatinine, guanidines, acid radicals, and excess electrolytes are exchanged into the dialysate. The bicarbonate, glucose, salicylate, electrolytes and other substances needed by the body in the dialysate are added to the blood, so as to achieve the therapeutic purpose of removing metabolic waste in the body, correcting water and electrolyte disorders and acid-base imbalance. The wor...

Problems solved by technology

[0027] The defects of the above-mentioned existing dialyzer reuse technology at home and abroad are: after the dialyzer is used, the blood coagulation tissue blocks some of the inner holes of the dialysis membrane, and it is difficult to wash it with water, so that the effective volume of the dialyzer drops sharply. Generally, it can only be used About 3 times it will be discarded

[0028] 1. When it is found that the first reuse is not cleaned, the high-pressure reverse osmosis water is likely to cause damage to the dialysis membrane during the second reuse cleaning;

[0029] 2. The second multiplexing process increases time and reduces efficiency

The dialyzer reuse process improves the dialyzer reuse quality to a certain extent, but has disadvantages such as long cleaning time, low work efficiency, and large damage to the dialysis membrane.
