Description

Field of technology

The utility model relates to a mobile filter for respiratory masks with UVC sources and an electronic control unit, which will find application to various types of respiratory brands for protection against infectious diseases caused by severe acute respiratory syndrome coronavirus, such as respiratory syndrome MERS-CoV, severe acute SARS-CoV respiratory syndrome and the identified coronavirus at the end of 2019 in Wuhan, Central China, called SARS-CoV-2.

BACKGROUND OF THE INVENTION

The severe acute respiratory syndrome coronavirus-2 is called (SARS-CoV-2), while the disease associated with it is called COVID-19.SARS-CoV-2 is a new strain of coronavirus that has not been previously identified in people.

It is still difficult to draw definitive conclusions about how the new coronavirus is spreading, but information so far shows that it is transmitted in the same way as SARS and some other pandemic influenza strains.

It is currently thought that this virus is transmitted from person to person. There is currently insufficient epidemiological information to draw specific conclusions about whether the virus is easily spread among humans. Transmission is thought to be mainly through droplets when people sneeze, cough or exhale.

Preventive measures include the use of respiratory masks as a means of protection, which prevent the spread of the infection by airborne droplets. These remedies are extremely necessary, especially for medical personnel who come into contact with sick carriers of SARS-CoV-2 in their daily work.

Due to the fact that no vaccine against SARS-CoV-2 has been found so far, special attention is paid to the precautions to prevent infection.

In currently used respiratory masks, the air filter physically restricts the passage of infectious microorganisms, but does not destroy them. The degree of protection depends entirely on the degree of permeability of the filter

They are known from patent documents AU 2020100228 A4, AU 2020100503 A4, WO 2009012752 A1 and KR 20190138151 A fabric masks on which a UV light source is mounted around the filter medium. These masks are a compact product whose parts cannot be used separately or replaced.

Known from US 2010132715 A1 chemical and biological protective mask, which has a filter with a high-intensity UV-disinfection system. The mask covers the user's nose and mouth and has an exhalation valve mounted on the mask part, an inhalation opening in the mask part, a filter box and a UV filter with a light tube. UV radiation is in the range of 240 nm 280 nm wavelength and is powered by a battery connected to a voltage regulator. According to the patent document, a solar cell is used to supply UV LED light directly or to recharge the battery, and the solar cell can be mounted on a visor attached to the mask. The chemical and biological protective mask according to the patent document has a specific construction and the parts of it cannot be used for other types of respiratory masks.

Technical essence of the utility model

The purpose of the utility model is to create a mobile filter for respiratory masks with UVC sources and an electronic control unit that can be used with existing respiratory masks, to have an extended service life and to ensure that U VC light is not missed outside. a device to prevent damage to the skin and eyes of the user of the mask and the people around him.

The goal is achieved with a mobile filter for respiratory masks with UVC sources and electronic unit

3818 a control UI, the body of which consists of a housing 1 on which are mounted an adapter 4 connected to a respiratory mask 2 and an adapter 5 connected to an air filter 3.

An inner compartment is formed in the housing 1, in which partitions 10, a fan 11 mounted in front of the adapter 5 and U VC sources 8, which are located in the upper and lower part of the inner compartment, are located.

In the upper outer part of the housing 1 is formed a socket 12, in which a battery 6 is placed, and in the lower outer part of the housing 1 is formed a socket 13, in which is a control electronic unit 7.

The battery 6, the UVC sources 8 and the fan 11 are operatively connected to the control electronic unit 7.

According to the utility model, the UVC sources 8 have a wavelength of 250 nm to 300 nm and are at least four.

Battery 6 is a rechargeable Li-ion rechargeable battery.

Partitions 10 are at least two.

The housing 1, adapter 4, adapter 5, partitions 10, socket 12 and socket 13 are made of polymeric materials.

According to the utility model, the flow of inhaled air passes from the air filter 3 through an adapter 5 to a mobile filter for respiratory masks with UVC sources and an electronic control unit 1. It then passes through a fan 11 which assists inhalation and prevents the existence of zones in which there is airflow retention. Barriers 10 ensure that radiation outside the UVC mobile filter 1 is prevented and the path of the inhaled air is extended in order to expose the sources of ultraviolet rays for a longer time. Through adapter 4, the inhaled air already disinfected enters the respiratory mask.

The advantages provided by the mobile filter according to the utility model are:

The mobile filter is a stand-alone device and can be mounted on all existing standard respiratory masks.

The presence of the fan 11 facilitates respiration and by delaminating the air flow, prevents the formation of sectors in which the air remains motionless, eliminating the possibility of pathogens surviving there.

The presence of barriers 10 prolongs the path and thus the exposure time, preventing UVC radiation from being let out of the filter according to the utility model and preventing damage to the skin and eyes of the user of the mask and the people around him.
