RU46664U1 - RESPIRATOR - Google Patents

Abstract

The proposed utility model relates to the field of medicine, namely to respirators for medical purposes and can be used for individual protection of a person from serious infectious diseases.

The respirator provides personal protection against pathogenic viruses and microorganisms.

For this, a respirator containing a half mask, an obturator and filters additionally contains a nozzle in the form of a ring, made with the possibility of mounting on the outside of the filters of the respirator. On the inner side of the ring there are ultraviolet LEDs connected to a portable power source. Ultraviolet LEDs are staggered in two rows.

Description

The proposed utility model relates to the field of medicine, namely to respirators for medical purposes and can be used in infectious diseases hospitals, during epidemics of viral and infectious diseases, both by medical workers and the public.

Respirators are used as devices for individual protection of respiratory organs from dust and harmful substances. The simplest respirator is a cotton-gauze dressing, which is used to protect against drip infection. There are two main types of respirators - isolated and filtering. Insulated respirators are used in case of insufficient oxygen content in the air, as well as in cases where the concentration of harmful substances and impurities in the air is very high and the use of filtering respirators is not reliable enough. However, the disadvantage of isolated respirators is their large weight and dimensions, since the respirator includes: oxygen bolon, respiratory bag 4, regenerative cartridge containing chemical absorbers, etc. It is not convenient to use, and if the metal case containing bound oxygen is damaged, the respirator itself may cause a fire or explosion.

One of the main advantages of filtering respirators is its lightness, compactness, portability and slight resistance to breathing. As a rule, a filter respirator consists of a front part and a filter. The front part can be made in the form of a helmet-mask or half mask. It should maintain tightness, fit tightly to the face and not put too much pressure on the skin. As a filter, filtering synthetic materials are used, which are currently being developed quite a few. Universal respirators are also widely used, which are used to protect respiratory organs from vapors, gases and aerosols that are simultaneously present in the air of the working area. The universal respirator consists of a half mask with a knitted obturator and replaceable filter cartridges with special absorption and aerosol filters.

For the prototype of the proposed utility model, a well-known respirator containing a half mask, an obturator and replaceable filters was selected (see BME, edited by Academician B.V. Petrovsky, third edition, M., Publishing House "Soviet Encyclopedia, 1984, p.614 )

A disadvantage of the known filter respirator is the inability to protect a person from viruses and pathogenic microorganisms, as well as spores of epidemic diseases (tuberculosis, AIDS, hepatitis, etc.).

The objective of the proposed utility model is to create a device that protects a person from pathogenic viruses and microorganisms of serious infectious diseases.

The problem is solved in that in a known respirator containing a half mask, an obturator and filters, the respirator further comprises a ring-shaped nozzle adapted to be mounted on the outside of the respirator filters, on the inside of which there are ultraviolet LEDs connected to a portable power source. At the same time, ultraviolet LEDs are placed in a ring in two rows in a checkerboard pattern.

The proposed utility model meets the criteria of "novelty" and "inventive step", since in the process of patent information research no sources of patent and scientific literature were found discrediting the novelty of the proposed utility model, nor were technical solutions with essential features of the proposed device.

The proposed utility model allows to obtain the following positive effect. The proposed device provides individual protection against viruses and microorganisms of severe epidemic diseases, such as AIDS, hepatitis A, B, C, etc. The device does not make breathing difficult, compact, can be used with any filter respirator manufactured by the industry. The development of the proposed utility model is based on the fact that, when irradiated with UV rays, the basement membrane of the microorganism breaks down and ozone is formed from oxygen. Among the biological effects of ozone, traditionally the first place is occupied by its bacteriological, fungicidal, and virucidal biological effect. The direct cause of the death of bacteria under the action of ozone is local damage to the plasma membrane, leading to the loss of viability of the bacterial cell and / or its ability to multiply. Ozone molecules interact not only with the components of the surface membrane, but, changing its permeability, lead after 10-20 minutes to the destruction of intracellular organelles. According to microbiological studies, ozone can kill all known types of grams.

positive and gram-negative bacteria, including Pseudomonas aeruginosa and Legionella, all lipo- and hydrophilic viruses, including hepatitis A, B, C viruses, spores and vegetative forms, all known pathogenic fungi and protozoa (see O.V. Maslennikov and KN Kontroshchikrva "Ozone Therapy. Internal Medicine", N. Novgorod, Vector-TiS Publishing House, 2003, p. 18) The officially established maximum concentration of ozone in the workplace is 0.2 mg / m ³ with an inhalation period ozone-oxygen mixture 8 working hours within a 40-hour working week. According to some authors, ozone in concentrations from 1 to 5 mg / l leads to the death of 99.9% of E. coli, Streptococcus faecalis, Mycobacterium tuberculosum, Criptosporidium parvum, Varavium and others within 4 to 20 minutes. It is known that the destruction of very persistent spores of Penicilium notatum requires an ozone concentration of only 0.1 mg / L. Given these figures and their recalculation of the ozone concentration for a certain were selected parameters of the proposed device.

Figure 1 shows the proposed utility model.

The respirator (figure 1) contains a half mask 1, an obturator (not shown in figure 1) and filters 2. The respirator further comprises a nozzle in the form of a ring 3 made with the possibility of fastening from the outside of the filters 2. Ultraviolet LEDs 4 are placed on the inner side of the ring connected to a power source 5. Ultraviolet LEDs are placed in a ring in two rows in a checkerboard pattern.

The proposed respirator operates as follows. On the outside of the filters of the filter respirator, a nozzle in the form of a ring is fixed. The power button ultraviolet LEDs bring into working condition.
