Description

Ultraviolet disinfection respirator

(I) technical field

Medical and sanitary articles necessary for human life. By ultraviolet irradiation, all pathogenic microorganisms in the respiratory gas are killed, the health of a wearer is protected, and toxic gas exhaled by the patient is prevented from polluting the environment, so that the blocking epidemic prevention tool for respiratory infectious diseases is provided.

(II) background of the invention

In order to prevent respiratory infectious diseases, the mask is worn by people most frequently. In a filtering manner, pathogenic microorganisms are prevented from outside the mask. The mode plays a considerable role in epidemic prevention, but if the epidemic prevention means is ideal and reliable, the serious situations that the epidemic situation is outbreak in a large area, the city is closed and the country is held against the new coronary pneumonia cannot occur.

We discuss the disadvantages of the existing masks:

the filter area undersize only in the front portion of mouth, in order to satisfy the breathing demand, gaseous just will pass the gauze mask at a high speed, and this leads to the gauze mask filter bed in, the external pressure difference is big, breathes unsmoothly, and the filter bed in, the external pressure difference is big makes the sealed more difficult of gauze mask four sides.

When a person coughs and sneezes, a large amount of toxic gas is sprayed instantly, the pressure on the inner side of the mask rises steeply, the person can not penetrate through a filter layer of the mask and can burst the periphery of the mask, and the unfiltered toxic gas carries pathogenic microorganisms to diffuse outwards, so that the toxic gas becomes an important cause of epidemic outbreak.

The curved surface of the human face is difficult to match. And the material of the fibrous mask filter layer is not suitable for realizing sealing with the facial skin.

The mask is worn to give people a feeling of unsmooth breathing, especially for patients with dyspnea.

Disclosure of the invention

1. The technical problem to be solved is as follows:

the problem of sealing is solved, the fine and dense filter layer of the mask can block the passage of pathogenic microorganisms, but great respiratory resistance is generated, and the leakage at the four sides of the mask is the biggest cause of infection. The special space curved surface of the face is difficult to form reliable sealing with the mask filter layer.

The problem of thorough disinfection is solved, epidemic propagation with the respiratory tract as a propagation way is avoided, and the epidemic propagation can be avoided only under the conditions that the inhaled gas is ensured to be free of pathogenic microorganisms and the exhaled gas is also free of pathogenic microorganisms.

2. Technical scheme

The sealing problem is solved:

a latex pad 4 with a smooth surface is made using latex which is excellent in elasticity and is not easily allergic, as a seal member for contact with the skin of a human face.

The mask 1 is formed by casting, drawing and blowing plastic, the part connected with the lock nut 21 is thicker, and the part of the face attaching edge 5 is very thin (about 0.2-0.3mm thick) which is similar to the thickness change of the plastic mineral water bottle. The four walls of the face mask 1 are contacted with the face of a person to form a substantially vertical state, the shape of the face of the person is different, the face-fitting edge 5 of the face mask 1 needs to be trimmed according to the shape of the face of the person, the trimming standard is that after the face-fitting edge 5 of the face mask 1 is inserted into the groove 6 of the latex cushion 4, the latex cushion 4 is completely fitted with the face of the person, and at the moment, adhesive is injected between the face mask 1 and the latex cushion 4.

The mask 1 is fixed by two elastic bands 3 around the back of the neck. The mask 1 is provided with an oxygen port 2 with a valve for patients to inhale oxygen.

Killing pathogenic microorganisms by using ultraviolet rays:

the most rapid, most thorough and most practical method for killing pathogenic microorganisms in the air is ultraviolet irradiation. The volume of air breathed by a person is limited. The energy consumption for killing pathogenic microorganisms is low. The pathogenic microorganisms can be killed completely within 1 second by using a low-power ultraviolet radiation lamp. The small power ultraviolet radiation lamp is a mature product and has a plurality of manufacturers. The rechargeable battery is used as the energy source of the low-power ultraviolet radiation lamp, and the moving range of a user is not limited.

The cylindrical killing chamber 24 is a part for killing pathogenic microorganisms, and the wall of the killing chamber 24 is made of a metal thin plate, and the inner wall is smooth like a mirror so as to reflect back ultraviolet rays and improve the killing efficiency. An ultraviolet lamp 36 is installed at the center line of the sterilizing chamber 24, and air flows around the ultraviolet lamp 36 to kill pathogenic microorganisms whether breathing or inhaling. The volume of gas inhaled per time is substantially constant when a person breathes. During inhalation, outside air enters the cylindrical sterilization chamber 24 and, provided the chamber is of sufficient length that the gas is irradiated by the ultraviolet lamp 36 for more than one second, all pathogenic microorganisms are killed. The volume of the sterilizing chamber 24 is designed, the volume of the sterilizing chamber is larger than the volume of gas breathed each time multiplied by the safety factor, and the safety factor is larger than 2.

The sucked air enters the upper part of the sterilizing chamber 24 through the gap between the three arms of the disk seat support arm 28 by taking the annular gap between the lower opening of the light shield 30 and the sterilizing chamber 24 as an inlet. The gas flows downwards around the ultraviolet lamp 36 for disinfection, and the disinfected gas is guided to the mask 1 through the hose 20 at the lower part of the disinfection chamber 24 for people to inhale.

The exhaled air is guided to the lower part of the sterilizing chamber 24 by the mask 1 through the hose 20, the hose 20 is locked by the locking nut 21, the exhaled air flow enters the sterilizing chamber 24 through a hole in the middle of the connector outer wire 23, the air flows upwards around the ultraviolet lamp 36 for sterilization, and the sterilized air flows through the lower opening of the light shield 30 at the upper part of the sterilizing chamber 24 and is discharged to the external space.

Patients often cough or sneeze due to respiratory diseases. At this time, the gas ejected by the patient has fast airflow and a large amount of pathogenic microorganisms, so that the inner baffle plates 25 and the outer baffle plates 26 are alternately arranged in the sterilizing chamber 24, the airflow repeatedly changes the movement direction in the sterilizing chamber 24 to generate vortex, the impact force of the airflow is consumed, the irradiation time of the gas under ultraviolet rays is prolonged, and the pathogenic microorganisms are thoroughly sterilized.

3. Advantageous effects

The living competition among species is not in progress, and the living competition ability of lower organisms is not low. Historically, the small pathogenic microorganisms have caused millions of deaths. The natural variation means of pathogenic microorganisms can make human being in a passive state. The epidemic situation shows that if the original mask is ideal and reliable in blocking the epidemic prevention effect, the serious situation that the epidemic situation is outbreak in a large area, the city is closed and the country is held up to resist the new coronary pneumonia does not occur.

The aim of the invention is to improve the integral blocking performance of the mask, which is the key of the epidemic prevention and has the simplest, most economical, most effective and only effective means for all respiratory epidemic situations. The money is invested for one person, and the harvest is the guarantee of safety and health. The method is an upgrading, updating and innovation for enterprises, provides urgent products for society, is the only way for the vigorous development of enterprises, and is a strategic safety reserve of technology and material for avoiding epidemic death and reburning and leading the country to develop the due steady and healthy state.

The invention aims to make a strategic safety reserve of corresponding technology and materials for an unexplained or more toxic respiratory epidemic situation.
