Manual cleaning method: manual cleaning of instruments mainly includes: fine, precise, sharp instruments, instruments that can not be immersed in water, instruments that can not withstand high temperature (93 ℃), as well as serious contamination of rust or residual secretion, with the machine can not be washed instruments.
Manual cleaning is done by physical means, in running water and detergent matching the contamination of the instruments, removing the dirt adhering to the instruments with brushes or cleaning cloths to achieve the purpose of cleaning.
The comparison of the cleaning effect of the instruments after surgery was observed by three methods: traditional cleaning, cleaning plus multi-enzyme immersion, and automatic washing machine cleaning. The cleaning effect of the cleaning plus multi-enzyme group was better than that of the other groups, and the results proved that the automatic washing machine was not the washing equipment that could thoroughly clean the instruments.
Conducted a variety of cleaning methods to observe the washing effect of medical devices, found that the smooth surface of the instruments can be manually cleaned to achieve both quality assurance, but also to save the cost of washing and improve the efficiency of the purpose.
The complex structure of the instruments can be disassembled parts must be disassembled carefully scrubbing, and pipelines, crevices, rough surfaces, joints, etc. should be selected from different types and sizes of brushes first manual preliminary scrubbing, to remove the large dirt, and then cleaned with a washing machine to ensure that the cleaning effect.
Through the observation of contaminated instruments washing method, that in the process of manual cleaning instruments, emphasize that attention should not be paid to the wire ball brushing instruments, so as not to leave brush marks on the surface of the device, so that the dirt or water in the traces of the deposit and cause corrosion and stains, but also the surface of the device will also be the protection of the film brushed away, accelerating the rusting of the device.
Mechanical cleaning method: mechanical cleaning is divided into automatic, semi-automatic, ultrasonic cleaning machine, long-dragon type and other forms, some cleaning machine with heating system and drying system.
At present, some domestic hospitals use mechanical cleaning, automatic spray cleaning machine cleaning surgical instruments before using multi-enzyme liquid soak instruments method, can make the same instrument surface, axial joints, the occlusal surface of the cleaning quality significantly improved.
The role of ultrasonic automatic cleaning machine washing is by high-frequency water extrusion to produce blisters to form a vacuum zone and produce tension, will be attached to the instruments on the dirt loose suction away, it is better than artificial cleaning is the reason it can clean the brush can not reach the dirt.
Through observation, it is found that purely mechanical cleaning on the residual organic matter of the instrument can not achieve the desired cleaning effect, and the use of multi-enzymatic liquid immersion manual brushing and then cleaning machine cleaning is more effective.
Machine cleaning and can not replace all manual cleaning, for some pipelines, precision instruments and more difficult to clean parts must be cleaned manually, in addition to cleaning equipment must be cleaned often and maintenance to avoid machine cleaning failure.
Low-foam multi-enzyme cleaning agent selection
Selection of low-foam multi-enzyme cleaning agent should be considered when cleaning agent cleaning effect, more choice of liquid, clear and transparent, no restriction on the water quality, no bubbles or less bubbles, uniformity and no impurities, with bleaching and cleaning functions and tips suitable for the water temperature of the cleaning agent. Maintenance after enzyme washing
New instruments do not have to remove rust, individual instruments with serious pollution can be used at any time 1:7 rust remover soak 5 seconds.
