Hemodialysis machine pipette washing and sterilizing device and method

Abstract

The invention discloses a hemodialysis machine pipette washing and sterilizing device and method. The hemodialysis machine pipette washing and sterilizing device comprises a pipette storing structure,a pure water supply circulating system, a hot wind drying system and a control system. In the washing process, the pure water is injected into a pipette storing container to a high-water-level sensor, at the moment, the pure water floods pipettes, a circulating part is utilized for sucking liquid from the bottom, thus the liquid level reaches a low-water-level sensor, then the circulating part drains the liquid, thus the liquid level returns to the high-water-level sensor, after being circulated many times, all liquid is drained from a bottom water outlet, then the pure water is injected again for washing, and motion is repeated; a constant-temperature hot wind machine is utilized for introducing constant-temperature hot wind into the pipette storing container to carry out drying; and during sterilization, the sterilizing process is added before the washing process. According to the hemodialysis machine pipette washing and sterilizing device, full-automatic washing, sterilizing and drying of the pipettes can be achieved, by means of the control system, all the parts are called to cooperate in the time sequence, and the washing and sterilizing efficiency and effect are improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device and method for cleaning and disinfecting suction tubes of hemodialysis machines. Background technique [0002] After the suction tube of the hemodialysis machine is used, it is necessary to clean and dry the inside and outside of the suction tube once a day, and disinfect, clean and dry the inside and outside of the suction tube once a week. The traditional method is that medical staff manually wash, soak, disinfect, and dry the suction tube through the water pipe. The workload of medical staff is heavy, and there are problems such as irregular operation, and the cleaning and disinfection effect is not satisfactory. [0003] In the prior art, for example, the previously published patent ZL201820185554.7 discloses a method of cleaning and disinfecting the pipette with heated water, which will cause accelerated aging of the pipette, which is not a disinfection ...

AI Technical Summary

Problems solved by technology

The traditional method is that medical staff manually wash, soak, disinfect, and dry the suction tube through the water pipe. The workload of medical staff is heavy, and there are problems such as irregular operation, and the cleaning and disinfection effect is not satisfactory.

[0003] In the prior art, for example, the previously published patent ZL201820185554.7 discloses a method of cleaning and disinfecting the pipette with heated water, which will cause accelerated aging of the pipette, which is not the disinfection method advocated by the manufacturer.

Patent ZL201820185554.7 adopts the method of flushing the inner and outer walls of the suction pipe with the nozzle, which cannot guarantee 100% cleaning of the suction pipe

It can be seen that none of these technical solutions can solve the technical problems existing in the prior art
