ABSTRACT
Objective:To investigate the ultrasonic cleaning machine in the equipment derusting effect of.Methods: Rusty instrument as rust 600, were randomly divided into two groups, experimental group (n=305) and control group (n=295). The first device in according to 1:270 proportion of organic pollutants in multi enzyme cleaning solution good, the experimental group will rust instrument containing stainless steel basket, in according to the proportion of 1:7(water temperature is 60℃) ultrasonic cleaning machine solution rust agent by ultrasound in 10 minutes, with a soft brush to wash; the control group will instrument in the water temperature in 60℃, solution rust agent 1:7 mixing ratio, non constant temperature for 10 minutes using a soft bristle brush. Observe and record the two rust rust indicators, and analysis.Results: The naked eye visual two groups of instruments derusting pass rate was not statistically significant (P<0.05); microscopy (5 times the magnifying glass) experimental group equipment derusting pass rate was significantly higher than that of the control group, there were significant difference between two groups (P<0.001); total flexibility in experimental group was significantly better than the instruments the control group, there were significant difference between two groups (P<0.001).Conclusion: The rusty instrument in a constant temperature of 60℃ plus ultrasonic cleaning descaling effect, improves the equipment clean quality and overall flexibility.
ABSTRACT
OBJECTIVE To save rust remover's cost,reduce the material consuming and ensure the cleaning quality of the instruments by changing the work model.METHODS According to the key factors of the increasing cost of the medical rust remover,adjust the work model properly,that is to say,set up target by know about the problems;confirm the measurement data of the problems;analyze the problems and figure out key minority;make strategy to correct the mistakes;and make the controlling measures to ensure effective implementation.Enforce organization management,and remove the rust collectively and grouply by time,by ration and by certain number of people.RESULTS The rust remover cost had been saved greatly and the cleaning quality had been improved distinctly,the number of scrapped medical instrument had been reduced.Compared with the period before improvement,it had statistic significance on difference(P
