Description

A long-term disinfection method for medical appliances

technical field

The invention relates to the technical field of medical disinfection, in particular to a long-acting disinfection method for medical appliances.

Background technique

With the development of public health, more and more medical instruments are used, such as suture needles, surgical scissors, trays, etc., so that the instruments must be strictly sterilized after use before they can be used next time. However, most of the current disinfection methods are relatively traditional, and the sterilized utensils will be contaminated with bacteria in a short period of time, making the utensils unsafe to use.

Contents of the invention

The technical problem to be solved by the present invention is to provide a long-term disinfection method for medical appliances.

A long-term disinfection method for medical appliances, comprising the following steps:

(1) Soak the dirty utensils in glacial acetic acid, and then put them together with glacial acetic acid in a -40°C freezer for 2 hours;

(2) Take out the utensils and melt to separate the utensils, then bury the utensils in a barrel filled with liquor distiller's grains and keep for 30 minutes;

(3) Take out the appliance and soak it in 83-88°C modified disinfectant solution for 1 hour, then remove the appliance and apply the mixed powder of medical titanium dioxide and medical zinc oxide evenly on the surface of the appliance, and wash the appliance with deionized water after 20 minutes;

(4) The appliance is subjected to radiation vulcanization in a closed room, and the radiation dose is 900-1200kGy;

(5) Dry, organize and stack the utensils neatly.

The modified disinfectant solution is made of the following raw materials in parts by weight: 15-22 parts of aloe extract, 4-8 parts of tea polyphenols, 25-35 parts of extract of Jasmine japonica, 2-3 parts of morpholinone, dihydroxy 5-12 parts of ethylamine, 8-14 parts of capric acid, 8-14 parts of allicin, 150-180 parts of purified water, all raw materials can be mixed and stirred evenly.

In the step (2), the temperature of distiller's grains is 45-55°C.

The radiation dose in the step (4) is 1050kGy.

The beneficial effects of the present invention are: the disinfection method of the present invention can kill all kinds of bacteria, the disinfection is thorough without residue, the process operation is easy to realize, and the sterilized utensils have certain resistance to bacteria. The amount is still within a safe range, making the appliance safer to use.
