Study On Cleaning Effect Of Recycling Equipment By Different Pretreatment

Purpose:To explore and compare the quality of regenerative instrument cleaning with different pretreatment methods,to find out the effective and safe method of cleaning equipment,to prolong the use time of regenerative equipment,to improve the qualified rate of disinfection and sterilization of regenerative equipment,Reduce the quality of the equipment due to the quality of the hospital infection caused by the purpose of infection.Method:Using the method of clinical research,from January to September 2016 in Changchun,a three-level hospital,after use and stay more than 3 hours moderate and moderate pollution of the 2000 hemostatic forceps,were randomly divided into four groups of 500 To put.Respectively,multi-enzyme + machine wash group,manual washing + machine wash group,hydrogen peroxide solution + machine wash group,multi-enzyme cleaning solution + ultrasonic cleaning + machine wash group.The results were compared with those of different pretreatment cleaning methods.Spss19.0 statistical software was used to compare the data rate with multiple samples.The results showed that the results were compared with those of the pretreatment cleaning method test of X2.Result:The results showed that the qualified rate of four kinds of pretreatment cleaning methods was different,and the qualified rate of multi-enzyme + machine washing was the lowest,and the qualified rate of multi-enzyme + ultrasonic + washing group was(P<0.05).The pretreatment and cleaning of manual washing and washing group,hydrogen peroxide and machine wash group were significantly higher than those in the control group(P<0.05),and there was no significant difference between the two groups(P<0.05).There was no significant difference between the two groups(P<0.05).There was no significant difference in the cleaning effect between the three detection sites of hydrogen peroxide and machine wash group(P>0.05).The clearance rate of the teeth was significantly lower than that of the surface The 5 times the light source magnifying glass detection equipment cleaning effect method:four kinds of pretreatment cleaning method axis,the teeth of the pass rate is different,which multi-enzyme + machine wash cleaning the lowest pass rate,multi-enzyme + ultrasound +washing group cleaning(P<0.05).The results showed that there was significant difference between the two grooups(P<0.05),manual scrubbing + machine wash group,hydrogen peroxide + machine wash group(P<0.05).Compared with the two groups,there were significant differences between the two groups(P>0.05).There was no significant difference in the cleaning effect between the three parts of the manual brushing + machine wash group and the hydrogen peroxide + machine wash group(P<0.05).ATP biometric method:four kinds of pretreatment cleaning methods at the surface,the Department of joints,teeth at the pass rate is different,in which multi-enzyme + machine wash the lowest pass rate,multi-enzyme + ultrasound + washing group cleaning qualified(P<0.05).The pretreatment of manual scrubbing + machine wash group and hydrogen peroxide + machine wash group was significant(P<0.05).and the ratio was higher than that of multi-enzyme(P<0.05).After two-two comparison,the qualified rate of cleaning at the teeth was significantly lower than that of the surface and the shaft(P<0.05),and there was no significant difference between the two groups.(P<0.05).There was no significant difference between the two groups(P>0.05).There was no significant difference between the two groups(P>0.05)).Hidden blood test paper detection method:four kinds of pretreatment cleaning method at the surface,the joints,teeth at the pass rate is different,which multi-enzyme + machine wash the lowest pass rate,multi-enzyme + ultrasound + washing group cleaning pass rate(P<0.05).The pretreatment and cleaning of manual washing and washing group,hydrogen peroxide and machine wash group were significantly higher than those in the control group(P<0.05)And the two groups were not significantly different;three detection sites,multi-enzyme + machine wash group,manual scrub + machine wash group,hydrogen peroxide + machine wash group,multi-enzyme + ultrasound + machine wash group of three tests(P>0.05).There was no significant difference between the two groups(P>0.05).Conclusion:The method of multi-enzyme + ultrasonic + machine wash group and hydrogen peroxide + machine wash group should be the main method.In the ATP bioluminescence cleaning method,the enzyme + ultrasonic + machine wash pretreatment cleaning method The qualified rate was significantly lower than the other three groups,the best results;occult blood test paper cleaning test,30g/L hydrogen peroxide + machine wash pretreatment pass rate was significantly higher than the other three groups,the best effect of removing blood stains;Comparison of different pretreatment methods and different instrument cleaning methods showed that the qualified rate of cleaning was lower than that of the surface of the device,and the qualified rate of the cleaning effect was the lowest,which was an important part of the cleaning equipment.Cleaning methods have their own advantages,hope in the equipment cleaning work should be based on the structure of the device and the degree of pollution to select the appropriate cleaning agent and cleaning methods to effectively improve the quality of renewable equipment cleaning to ensure that the regeneration of equipment disinfection,sterilization work smoothly,and then prevent And control the incidence of hospital infection,to ensure the safety of patients,while reducing the patient's hospital stay,reduce the economic burden.
