Conduit sterilizer

Abstract

A sterilizing apparatus of pipeline used for blood dialysis is composed of intermediate water tank, water supplying valve, output valve, delivering pipeline and heater matched with external surface of said delivering pipeline.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a pipeline sterilization device in hemodialysis. Background technique [0002] At present, the pure water used in hospitals for hemodialyzers is treated by water treatment equipment to meet the requirements of sterile pure water, usually through two-stage reverse osmosis, and then transported to the hemodialyzers in the dialysis room through pipelines, supplying and demanding blood For dialysis patients. Since it is impossible to completely kill the microorganisms in sterile pure water, the European Pharmacopoeia stipulates that less than 10 microorganisms / ml are allowed, and these residual microorganisms will slowly multiply in the pipeline. The pipe wall cannot be ideally smooth, and the flowing water forms an uneven flow rate, and the flow rate near the pipe wall is much slower than that in the center of the pipe. When the temperature is suitable, it will rapidly mul...

AI Technical Summary

Problems solved by technology

Sterilization with this method is to use the pure water in the original intermediate water tank in the water treatment equipment to heat. First, it needs more energy. Second, it does not need so much hot water during sterilization, but it is heated to near boiling Water cannot be used for hemodialysis and must be drained, so there is more waste
