Dead-space-free water supply device for hemodialysis

Abstract

The invention discloses a dead-space-free water supply device for hemodialysis. The dead-space-free water supply device comprises a pure water storage device, a pure water inlet is formed in the upperportion of one side of the pure water storage device, and a pure water outlet is formed below the pure water inlet; a circulating water outlet is formed in the side, away from the pure water inlet, of the pure water storage device; a circulating water inlet is formed in the bottom of the pure water storage device, and the circulating water outlet is connected with one end of a circulating main water pipe; the other end of the circulating main water pipe is connected with the circulating water inlet; the portion, close to the circulating water inlet, of the circulating main water pipe is provided with a first booster pump; a plurality of water supply branch pipes are branched on the circulating main water pipe, and the end, far away from the circulating main water pipe, of each water supply branch pipe is closed. According to the device, the design is novel, the structure is simple, the use is convenient, the layout is reasonable, pure water in the water pipe flows circularly, the deadspace is eliminated, the environment for bacteria breeding is eliminated, the cleanliness of the pure water is guaranteed, and the device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of hemodialysis, in particular to a dead space-free water supply device for hemodialysis. Background technique [0002] The dialysis treatment in the hospital requires a large amount of pure water (dialysis water / reverse osmosis water) supply, which directly participates in the treatment. The quality of water directly affects the effect of treatment. The growth of microorganisms and the increase of botulinum toxin in the water will bring danger to the patients under treatment, and even cause death in severe cases. Therefore, the safety of water supply for dialysis is the top priority in dialysis treatment. In the prior art, the dialysis treatment of the hospital adopts the method of the dialysis center more, uses many dialysis machines simultaneously, and some hospitals reach more than 100. The water supply pipeline for dialysis water is very long, generally more than 100 meters, which brings the condition...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of dead space formed in the connecting pipe between the main water supply pipe and the dialysis machine in the prior art, and the pure water inside cannot flow, resulting in the growth of bacteria in the water, and proposes a non-dead space for hemodialysis.
