Abstract:
Objective Exploration of best effect on washing medical instrument between automatic cleaning sterilizer and ultrasonic cleaners.Methods Suppose washing method A and method B.A:directly put medical instrument into automatic cleaning sterilizer,wash,sterilize and dry it step by step.B:place medical instrument into ultrasonic cleaners,wash with ultra sonic,shower with cool water,sterilize and dry with hot water.Results By comparison,after washing method A,there remains 0.33‰ residue on the medical instrument while after B there are 0.03‰ remains.It has an evident difference between result of the two methods(?~2=46.546,P=0.000).Especially on the cleaning result of saw-shaped medical instrument:A method has 0.52‰ residue while method B is 0.04‰,which is of great significance.But there exists no significant difference of washing result on non saw-shaped instrument(?~2=2.667,P=0.102).Conclusion Ultrasonic cleaners can reach the optimum washing effect on saw-shaped medical instrument,with a great decline on residue after cleaning.And automatic cleaning sterilizer can wash large quantity of non saw-shaped,saving labor and enhancing efficiency by automation cleaning process.Therefore,adpoting different equipment to wash different instrument can efficiently improve cleaning effect and ensure safe and qualified stelization.
