Abstract

To shorten the time of sterilization, air at the heating stage and sterilization exposure is supplied through air displaced from one point to another at a temperature of 160-180 ° C at a speed of 3-10 m / s. After sterilization exposure, turbulent air flows with a temperature of 18-20 ° C are continued to be introduced into the chamber. with Сд С5 О СЭ

Description

This invention relates to medicine and concerns the sterilization of medical objects.

The aim of the invention is to reduce the sterilization time.

The method is carried out as follows.

The sterilizer chamber is loaded with sterilized objects, for example, Petri dishes, laboratory glassware, syringes, etc., until it is completely filled and sealed. At the stage of heating the chamber and the objects placed in it, in the closed chamber at points displaced one relative to another, hot air is introduced at 160–180 ° C at a speed of 3–10 m / s. Hot air is injected until the temperature in the chamber reaches 180 ° C, after which the exposure is started. At the same time, turbulent air flows continue to be introduced into the chamber in order to maintain the desired disinfection temperature therein.

At the end of the sterilization exposure, cooling is started during which the air preheating system is turned off and the turbulent flows of already cooled air are continued to enter the chamber at .18–20 ° C at a speed of 3–10 m / s.

Example 1. Petri lumps are inserted into the chamber in an amount that ensures that the chamber is 100% loaded. After that, the chamber is hermetically sealed and they begin to introduce hot air in a displaced one relative to the other by a turbulent flow at a speed of 3 m / s. Heating the chamber to 180 ° C lasts 40 minutes. Then, the exposure is started, during which turbulent air flows continue to be introduced into the chamber in order to maintain the desired disinfection temperature in the chamber. At the same time, the temperature difference in the chamber does not exceed 12 ° С. At the end of the sterilization exposure shut off the air heating system and continue to introduce turbulent into the chamber

flows of air cooled to 18–20 ° C at a speed of 3 m / s for cooling. Sterilization and cooling for 60 and 20 minutes, respectively.

Example 2. The ca. measure is filled with laboratory glassware. Air is introduced into the chamber in turbulent flows at a speed of 7 m / s. The stages and temperatures of the environmental flows, as well as the process technology, are identical to Example 1. The chamber is heated to 180 ° C for 25 minutes. The drop of the tel-1 floor is 8 ° C. The duration of exposure and cooling, respectively, 60 and 15 minutes.

Example 3. The chamber is filled with syringes. Air is introduced into the chamber by turbulent flows at a speed of 10 m / s. The stages and temperatures of the air flow, as well as the process technology, are identical to Example 1. The heating of the chamber to 180 ° C takes 15 minutes. Temperature difference

Thus, the proposed method for
