Research on effectiveness evaluation and analysis equipment derusting for ultrasonic cleaning machine / 中国医学装备

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 1270 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 17(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 17 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.
