Description
Technical Field
The utility model relates to the technical field of water treatment systems for hemodialysis, in particular to a water treatment disinfection device for hemodialysis.
Background
The contact of water with blood in hemodialysis treatment is achieved by only one semipermeable membrane, which is not selective for the substances passing through it. Normal individuals orally ingest about 15L of water per week, while hemodialysis patients' blood is exposed to large volumes of dialysate, requiring at least 360L of dialysis water per week. Therefore, the need for purity of the dialysis water is very important, and the use of contaminated dialysis water and dialysate can cause a series of acute and chronic complications. And proper disinfection of water treatment systems is one of the key means to ensure dialysis patient quality of life, safety of treatment, and reduce dialysis complications.
The qualified water treatment system can remove most chemical substances and microorganisms in water, but biological pollution cannot be stopped in the water treatment system, bacteria can grow and propagate on the reverse osmosis membrane, and the bacteria can gradually penetrate through the reverse osmosis membrane to enter the pure water system. In addition, the water supply system behind the reverse osmosis membrane is also subject to bacterial invasion and secondary pollution. And the bacteria will quickly multiply once they enter the pure water system part, since the pure water part is particularly suitable for bacterial growth. No matter how advanced the water treatment system for hemodialysis is, the biological pollution can not be thoroughly stopped and the disinfection maintenance is not needed. After bacteria are propagated, if the bacteria cannot be killed for a long time, a biological film is formed inside the reverse osmosis film and the reverse osmosis water conveying pipeline, and once the biological film is formed, the water treatment system enters a serious pollution state. Biofilm is a very difficult contaminant to remove and contains a large amount of bacteria and endotoxins, which causes a drastic decrease in the quality of dialysis water, thus requiring a hemodialysis water treatment sterilizing apparatus.
However, the existing water treatment and disinfection device for hemodialysis has some defects in the use process, and needs to be improved, the residual degree generated by the existing water treatment and disinfection method for hemodialysis is relatively high, and the environment is polluted in the discharge process. Secondly, the existing disinfection device can generate the problem of chlorine (Cl 2) residue, so that the improvement is made, and the water treatment disinfection device for hemodialysis is provided.
