Disinfection methods ᐉ What methods are used for disinfection
Earlier we considered the types of disinfection . Recall that disinfection is prophylactic and focal. The latter, in turn, is divided into current and final.
Preventive disinfection is carried out in order to prevent the occurrence and spread of the pathogen in the environment. Focal disinfection is carried out in the environment of the infected patient (current) and after its isolation, discharge or transfer to another department (final).
What methods are used for disinfection?
There are five main methods of disinfection: chemical, physical, mechanical, biological and combined . Each of these methods is used in practice, both separately and in combination with others.
Chemical disinfection method
Chemical - the main method of disinfection, which is the use of various chemicals and their compounds for the destruction of pathogenic and conditionally pathogenic microorganisms on surfaces, inside objects and environmental objects, as well as in air and various substrates.
The main methods of disinfection with the use of chemical disinfectants:
irrigation of treatment facilities using special disinfection technology;
applying an aerosol disinfectant to the treatment objects with a spray;
immersion in the working solution of the disinfectant of dishes, medical devices, manicure tools, patient care products, equipment, etc .;
wiping various surfaces with a cloth moistened with a disinfectant working solution.
Preparations that are used for disinfection must meet a number of requirements, including: a wide range of antimicrobial activity, safety for humans and the environment, good water solubility, effectiveness when interacting with organic pollutants, neutral odor and others
Physical method
Disinfection by the physical method is carried out with the help of the impact on the object of disinfection of various physical factors: boiling, piercing, burning, using the action of ultraviolet radiation, etc.
The basis of the physical method is heat treatment. Most pathogens die at 60-70 ° C, but their spores are able to withstand higher temperatures.
Selection of a specific method, be it boiling or exposure to ultraviolet, depends on many factors, including the purpose of disinfection, the type of object being treated, the type of pathogen, the conditions in which disinfection and others take place.
Mechanical disinfection method
Mechanical disinfection is carried out in order to reduce the concentration of microorganisms in environmental objects. Mechanical methods include wet cleaning, washing hands, removing the contaminated soil layer, filtering the water, cleaning the rooms with a vacuum cleaner, etc.
It should be noted that mechanical disinfection does not destroy microbes, but only partially removes them from the objects of disinfection, performing auxiliary function. This method is also used for sanitizing people, filtering air, water and other liquids, etc.
All mechanical techniques are aimed at:
cleansing the treated objects from dirt, grease and protein particles;
removal of a certain number of microorganisms on the surface of human hands, objects, in the air and in water.
The quality of mechanical disinfection directly depends on the device used for this purpose. For example, wet cleaning with rags and brushes gives significantly better results than dry.
Biological and combined methods
The biological method of disinfection consists in the destruction of pathogens of infectious diseases by antagonist microbes.
Antagonism of microorganisms - the type of relationship of microorganisms, in which one strain completely destroys or slows the growth of another.
In modern disinfection, this method is no longer used because of its complexity.
The combined method is based on a combination of several of the above disinfection methods.
