Device and method for cleaning and disinfecting medical speculum by composite frequency ultrasonic wave and acidifying water

Abstract

The invention relates to complex frequent ultrasonic wave with for specula and sterilizing unit through acidified water cleaning and method. The device comprises bi-box acidified water production tank fixed at the underlayer of the frame and provided with electrolysis electrode, double deck cleaning sterilizing chamber fixed at the top layer of the frame and provided with complex frequent ultrasonic wave emission head, control panel box and control part fixed at the middle of the frame front, pipes fixed at the side of the frame and used for transmitting tap water, acidified water, alkaline water and waste water, pump and valve. The method comprises boot self-checking phase, high water level judgment phase of acidified water production tank, power source starting phase for producing acidified water, production finish judgment phase of acidified water, high water level judgment phase of ultrasonic cleaning sterilizing chamber, manually predetermination phase of sterilization time, power source starting phase for cleaning and sterilizing, phase of power source of ultrasonic wave shutting and start of waste water discharge pump to exclude waste water, low water level judgment phase of cleaning sterilizing chamber, and shut phase of waste water discharge pump.

Description

technical field [0001] The invention relates to ultrasonic cleaning, decontamination and disinfection technology, in particular to an invention of a medical speculum compound frequency ultrasonic and acidified water cleaning and disinfection device and method. Background technique [0002] Endoscopy has extremely important use value for the diagnosis and treatment of diseases, but with the popularity of endoscopy, in recent years, there have been reports of acute gastric mucosal lesions after gastroscopy, HBV, HCV, HIV, TB, HP Salmonella, syphilis The infection of H. pylori, especially the cross-infection of H. pylori, has made the safe use of endoscopes an international concern. Therefore, it is necessary to adopt effective cleaning and disinfection techniques. To this end, endoscopic nurses and technicians are specially trained, and a disinfection standard system is formulated to eliminate and reduce the risk of iatrogenic infection caused by endoscopic examination. Endos...

AI Technical Summary

Problems solved by technology

[0011] 1. There are more patients undergoing endoscopic examination per unit time, and the cleaning and disinfection time is longer;

[0012] 2 Using a special automatic cleaning and disinfection device saves manpower and control time, but it is expensive. Only one endoscope is cleaned at a time, and the efficiency is low. There is a possibility of recontamination

[0013] 3. The endoscope lumen system, flexion and connection junctions are difficult to clean, the air supply / water supply lumen is too small (1.0mm-1.2mm) to wash, and the valve disc of the biopsy port cannot be sterilized

[0015] 5 The disinfection problem of the endoscope disinfection machine itself has yet to be solved
