RU151849U1 - UNIVERSAL RESPIRATOR - Google Patents

Abstract

A universal respirator containing: a filtering and absorbing half mask made of polymeric material, an exhalation valve, an aluminum nose plate and elastic bands of the headband, characterized in that an additional filtering element made of fibrous ion-exchange material is installed in the filtering and absorbing half mask.

Description

The utility model relates to personal protective equipment, in particular to personal protective equipment for respiratory organs, designed to protect against the negative effects of toxic substances of general toxic and asphyxiating effects, radioactive and ground dust, as well as toxic gases and vapors.

Various designs of filtering respirators are known, which are described in GOST 12.4.191-99 “Filtering half masks for protection against aerosols”; "Protection against weapons of mass destruction." Edited by Myasnikov V.V., Textbook. - M .: Military Publishing, 1989; “A textbook of the sergeant of troops of the Russian Chechen Republic of Battalion” - M .: RIC of the RF Ministry of Defense, 2006 and others. The most widely used in the Armed Forces of the Russian Federation is the R-2 filter respirator, which consists of a filtering and absorbing half mask with a bag of filtering materials, a cap and is designed to protect respiratory organs from radioactive and ground dust. The principle of operation of the filtering respirator is based on the fact that the respiratory organs are isolated from the environment by a filtering and absorbing half mask, and the inhaled air is cleaned in a bag of filtering materials by a filtering and absorbing half mask.

However, this design has a significant drawback, expressed primarily in the targeted use of certain insulating materials for the manufacture of filtering and absorbing half masks that neutralize the negative effects of specific toxic substances of general toxic and asphyxiating effects, as well as radioactive and ground dust (“Protection against weapons of mass destruction, radioactive and potent toxic substances. "Textbook. - M.: Military Publishing House, 1992).

The design of the filtering respirator, adopted as a prototype (“Protected from weapons of mass destruction.” Edited by Myasnikov VV, Textbook. - M .: Military Publishing House, 1989), allows you to protect your respiratory system from aerosols, radioactive and ground dust. A filtering respirator containing a filtering and absorbing half mask, an exhalation valve, universal cuffs, adjustable belts, neutralizes the negative effect of fine particles on the respiratory system.

The disadvantage of the prototype is the lack of protection against toxic gases and vapors.

The utility model solves the problem of eliminating the negative effects of toxic gases and vapors on the respiratory system by passing inhaled air through an additional filter element of fibrous ion-exchange material located in a filter-absorbing half mask.

The task is achieved by the fact that in the filtering and absorbing half mask of a universal respirator, a filtering element is made of fibrous ion-exchange material, which purifies the inhaled air of radioactive and ground dust, as well as of toxic gases and vapors.

A universal respirator (Fig. 1a), contains a filter-absorbing half mask of polymer material 1, an exhalation valve 2, an additional filter element 3, an aluminum nose plate 4 and elastic bands of the headband 5.

The principle of operation of a universal respirator (Fig. 1b) is based on the fact that the inhaled air containing toxic substances of general toxic or asphyxiating action, radioactive or ground dust, toxic gases or vapors passes the first cleaning stage through a filter-absorbing half mask made of polymer material 1 (Fig. 1). 1a) in the area of the respiratory system, after which it enters the second stage of cleaning, which includes an additional filter element of fibrous ion-exchange material, installed under the filter-absorbing her half mask in front of the respiratory system 2 (Fig. 1A), then the purified enters directly into the respiratory system.

Comparative analysis with the prototype shows that the claimed design of a universal respirator, consisting of two stages, allows you to clean the inhaled air not only from aerosols, radioactive and ground dust, but also from toxic gases and vapors.
