Preparation of disinfectant solutions of different concentrations. Preparation of disinfectants

This is the destruction of vegetative forms of pathogenic and non-pathogenic microorganisms on various equipment, equipment, utensils, in the indoor air, and on the hands of personnel.

EQUIPMENT: oilcloth apron, rubber gloves, sealed goggles, four-layer gauze bandage or respirator, additional gown, scarf, containers for disinfection, dry bleach or chloramine, scales or measuring container, water, soap, towel, hand cream.

SAFETY

The preparation of disinfectant solutions is carried out by a specially trained person - a disinfector. Preparation is carried out in a well-ventilated area using special clothing, rubber gloves, sealed goggles and a four-layer gauze bandage. Store disinfectants in places inaccessible to children and persons not involved in disinfection. Containers with disinfectants must have tight-fitting lids and be labeled. Each container must have a label indicating the name, concentration, as well as the date of preparation, expiration date, and the name of the person who prepared the solution. The supply of disinfectants is stored in a dry, dark place, a cool room under lock and key. If disinfectants come into contact with eyes or mucous membranes, rinse running water. After using the solution, wash your hands with soap and apply any cream.

Most frequently asked question, which customers ask in the support chat of our online store - how to properly prepare a working solution of a disinfectant. This question is usually addressed by ordinary consumers, so it would be appropriate to collect all the information on this issue in one review.

To begin with, I would like to draw your attention to the following: Always strictly follow the instructions for the disinfectant!

The instructions indicate the requirements for the preparation of working solutions disinfectants, which the manufacturer considered important for a particular disinfectant.

Manufacturers of disinfectants adhere to some general rules, which are valid for preparing working solutions of almost all disinfectants. For example:

• The dishes must be chemically neutral, clean, without traces of rust. Usually this enamel cookware(without damaging the enamel), glass or plastic containers
• For cooking, clean, cold water is usually used. drinking water. If the manufacturer requires distilled water, this will be indicated in the instructions for the disinfection solution.
• Some drugs can be used not only in the form aqueous solution, but in the form of aqueous-alcoholic. To prepare such disinfectants, not 2 components are used, but 3.
• Persons under 18 years of age and not suffering from allergic diseases and increased sensitivity to chemicals.
• When working with the product, the skin of your hands must be protected with rubber gloves.
• Measuring containers must be clean, dry and chemically neutral. It is highly advisable to use separate containers for each component of the working solution.
• During all work, avoid contact of the product with eyes and skin.

The key concept for preparing a working solution of a disinfectant is concentration, which implies the share of the disinfectant in the total volume of the working solution. Please note that usually the concentration of the disinfectant for different modes treatments and different treated surfaces differ, sometimes significantly. Concentration is a relative concept and therefore is true for any disinfectant, that is, a 1% working solution of the drug Alphadez, or any other means that the composition contains 1/100 part of the disinfectant and 99/100 parts of water.

Below is a universal table for preparing working solutions for disinfection in the range of 0.1% - 4%. Other concentrations can be calculated from the table data using the rules of ordinary proportion.

Concentration of working solutions of disinfectants

Preparation of disinfectant solutions in accordance with the requirements of the instructions for use of the manufacturer's disinfectant used

General information. Disinfection of medical products chemical method(on surfaces, as well as in their channels and cavities) are carried out with the aim of destroying pathogenic and opportunistic microorganisms: viruses (including pathogens of parenteral viral hepatitis, HIV infection), vegetative bacteria (including mycobacterium tuberculosis), fungi (including fungi genus Candida). All products must be disinfected after use on patients. After disinfection, the products are washed tap water, dried and used as intended or (if indicated) subjected to pre-sterilization cleaning and sterilization. For disinfection, drugs are used that are approved for use by the Ministry of Health of the Republic of Belarus and if there are approved instructions for their use.

Indications: disinfection of medical instruments, care items, equipment, surfaces, etc.

Workplace equipment:

- facilities personal protection: a) waterproof apron; b) gloves; c) mask; d) safety glasses;

Manipulation table; - container with lid; - disinfectant;

Instructions for use of disinfectant, pen

Preparatory stage performing the manipulation.

1.Remove all jewelry from your hands (rings, watches).

2. Carry out hygienic hand antiseptics, wear:

Apron, gloves, mask, safety glasses.

The main stage of the manipulation.

3. Measure out the required amount of disinfectant in a measuring cup.

4. Preparation of solutions is presented in Table 1.

Table 1. Preparation of solutions (per 1 liter)

5. Pour (pour) the disinfectant into a marked container and add water to 1 liter.

6. Stir the solution.

7. Close the lid.

8. Fill out the label: indicate the name of the disinfectant solution, concentration, exposure, date and time of preparation, and sign.

9. Remove personal protective equipment, wash your hands, perform hygienic hand antiseptics.

Note: Working solutions of disinfectants with a cleaning effect are prepared by adding concentrate to water (to avoid the formation of excessive foam).

Disinfection of used medical instruments (single and multiple use), medical devices (hereinafter referred to as medical devices), dressings, care items, surfaces according to regimes taking into account exposure time

The wiping method is recommended for products and their parts that are not in direct contact with the patient. The method of wiping twice with a calico napkin or gauze soaked in a disinfectant solution can be used. It is not recommended to use products containing aldehydes or formaldehyde using the wiping method to avoid toxic side effects for personnel. The disadvantage of many products from these groups is their ability to fix organic contaminants on the surface and in the channels of products. To avoid this, the product must first be washed from contamination in compliance with anti-epidemic measures, and then disinfected.

At the end of the disinfection period, the products are washed with running water and used for their intended purpose or subjected to further pre-sterilization cleaning and sterilization.

In order to prevent the development of resistance of microorganisms circulating in healthcare facilities to disinfectants, it is recommended to periodically (at least once a quarter) alternate preparations, which should contain different active ingredients.
