Rinse after use, rinse immediately with warm water or cold water equipment, remove all the blood, body fluids and tissues. Dry attachments may damage the instrument surface and make it difficult to clean. Do not use hot water to wash, because it can condense protein substances. Clean technology time, temperature and stirring play an important role in the process of cleaning. Time - — The efficiency of cleaning chemicals usually depends on the time, temperature, — Higher temperature of the solution can be better to clean mixing. Either manually or ultrasound, it helps to loosen dirt on the surface of the instrument. 一个。 Ultrasonic cleaning is the most effective cleaning method. Ultrasonic cleaning is the result of air vibration phenomenon. Vibration waves in solution micron level bubble, grows with the alternating stress. When they reach the resonance, even in the smallest crack, air bubble also can produce a kind of force to remove dirt and particles. Compared with plain water, the use of ultrasonic cleaner has greatly increased the rate of cavitation. 1. According to the manufacturer's suggested that the mixture of enzymes or other neutral pH or weak alkaline detergent. 2. When necessary, using deionized water. 3. Run the ultrasonic cleaner for a few minutes, make the solution degassing and get the right temperature. 4. Instruments in the open position, to be included in the ultrasonic cleaner. Don't let the instrument with razor blades contact other instruments, all equipment must be fully immersed in water. 5. Please do not placed in the same cleaning cycle dissimilar metals ( Stainless steel, copper, chrome plating, etc. ) 。 6. Instruments should be dealt with in the detergent 5 to 10 minutes. 7. Rinse instruments, to remove the ultrasonic cleaning solution, and any remaining dirt. 8. Thoroughly with clean towel dry the instrument. That minimize the risk of corrosion and to form water. 9. Using spray lubricant in hinge to improve the function of the instrument. B。 Automatic washer disinfector follow the manufacturer's recommendations. In the final rinse circulation lubrication equipment before and after the sterilization cycle. C。 Manual cleaning 1. Using hard plastic cleaning brush. Do not use steel wool or steel wire brush. 2. Use only the neutral pH of detergent. If there is no correct flushing, low pH cleaner could damage the stainless steel surface protection and cause black stain. High pH cleaner may lead to a brown stain on the surface of the deposit, it may interfere with the smooth running of instrument. 3. Carefully brush sophisticated instruments, if possible, separate them with the ordinary instrument processing. 4. Check all the equipment surface, make sure they are clear clean, no stains and organization. Check the function of each instrument and status is normal. Scissors blade should be smooth sliding, the blade may loose when in the closed position. Check whether the tweezers tip is aligned correctly. Hemostatic forceps and the needle should not show light between the jaw, they should be easy to lock and unlock, and joint should not be too loose. Check wear needle seat grip. Check the cutting tools and cutting tools, ensure its blade sharp and in good condition. 5. Thoroughly rinse under running water equipment. Wash, opening and closing the scissors, hemostatic forceps, needles and other hinged tools, to ensure that can wash 6 hinge region. Thoroughly with clean towel dry the instrument. That minimize the risk of corrosion and to form water. Using spray lubricant in hinge to improve the function of the instrument. D。 Soak when other cleaning method is not practical, large precision instrument can immerse in the corrosion inhibitor. Suggested to wash and dry after soaking.
