1 disinfection and sterilization of medical equipment

2% glutaraldehyde (alkaline, acidic, neutral) can be used for disinfection and sterilization of various medical devices that are not afraid of moisture. The clean and dry instrument is completely immersed in the aqueous solution of glutaraldehyde at normal temperature, and sterilization can be achieved by disinfecting for more than 10 hours in 30 minutes. Regardless of the preparation, 0.5% sodium nitrite should be added as a preservative at the time of use, but only one month can be stored once the preservative is added, and alkaline glutaraldehyde can only be used continuously for 1-2 weeks.

2 endoscope disinfection and sterilization

Glutaraldehyde is the drug of choice for endoscopic disinfection. At present, the application of endoscopes is extensive, the variety is varied, and the precision of manufacturing has reached a new level, but the requirements for disinfection and sterilization are also getting higher and higher. Many types of modern endoscopes are not resistant to high temperatures and are susceptible to corrosion, so most endoscopes are sterilized or sterilized with glutaraldehyde. The correct operation procedure for disinfecting or sterilizing glutaraldehyde is to first treat the contaminated items in a harmless manner (the endoscope can be directly cleaned), and the endoscope can be cleaned with 0.2% effective chlorine cleaning disinfectant, and then rinsed and then used. Carefully wash the enzyme or enzyme detergent; rinse, rinse the detergent with water; dry,

The washed equipment should be dried; sterilized, completely immersed in a 2% glutaraldehyde solution for a specified period of time, and then rinsed off the residual glutaraldehyde with sterile distilled water to be used or dried. save.
