The invention relates to a method and device for cleaning medical device, even the narrow part of the medical device, with a high efficiency. The invention involves using ozone to contact the medical device to clean the medical device. The method further includes using a cleaning solution to clean the medical device. The method further includes the step of accumulating the cleaning solution and recycling the cleaning solution after it is used to clean the medical device. In the accumulating step, ozone is introduced into a liquid reservoir t to mix with the cleaning solution. In another aspect, the invention includes using a cleaning solution to clean a medical device and utilizing ozone gas to contact the medical device cleaned with the cleaning solution to achieve the goal of cleaning the medical device. The cleaning device is characterized in including an ozone gas generator and a cleaning unit configured to clean the medical device with the ozone gas generated by the ozone generator. The cleaning device may further include a control unit configured to control the ozone concentration. The cleaning device may further include a gas processing unit to process the ozone gas in order to recycle the ozone gas.本發明係關於一種效率高且連醫療器具之細窄部分都可洗淨之醫療器具之洗淨方法及醫療器具之洗淨裝置。藉由使臭氧氣體接觸醫療器具,而洗淨上述醫療器具。1...醫療器具洗淨裝置11...吸氣口12...洗淨槽用門16...臭氧產生單元17...洗淨槽18...供水口19...氣體處理單元20...排氣口21...風扇22...加熱器23...蓄水槽24...排水口
