Abstract

The invention discloses a special disinfectant for medical instruments and a preparation method thereof. The special disinfectant comprises the following components by mass percent: 1-4.5% of peracetic acid, 1-30% of hydrogen peroxide, 1-20% of glacial acetic acid, 0-25.5% of active agent, 20-96.5% of deionized water and the balance of acidic substance hydrochloric acid, and the total mass percent of the components is 100%. The main raw materials are composed of four broad-spectrum disinfectants including hydrogen peroxide, peracetic acid, glacial acetic acid and citric acid, each raw material can be used independently for disinfection and sterilization, the disinfection requirements of medical instruments can be met after the raw materials are mixed according to a scientific proportion, the multiple functions of sterilization and cleaning are achieved, and meanwhile high efficiency, safety and compatibility are considered.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, relates to a special disinfectant for medical instruments, and also relates to a preparation method of the special disinfectant for medical instruments. Background technique [0002] High-precision medical devices are becoming more and more popular in modern medicine, and it has become a normal trend to use high-precision medical devices to diagnose patients' conditions. Medical devices need to be disinfected after each patient is diagnosed to prevent cross-infection between patients. The conventional disinfection method is to use hydrogen peroxide or medical alcohol to wipe and disinfect. Although this method is simple and fast, the sterilization effect is not satisfactory. If the medical device is sterilized with a strong oxidizing disinfectant, the strong oxidant in the disinfectant will corrode the medical device, which may cause the device to fail or the test results to be biased...
