Abstract

The present invention is a positive pressure mask device for preventing corona virus infection. The sterile air supplied to the nasal mask (FIG. 1) from a filter-equipped blower (power motor pump) through a pipe is inhaled through the mouth and nose, and the virus particles coming out together in the exhalation are inhaled. Contaminated air is partitioned and blocked with an inner mask (FIG. 3) to a minimum amount, and all immediately pass through the discharge pipe through the discharge filter (FIG. 4, 43) to collect virus particles under reduced pressure and release only sterile air into the atmosphere. . In particular, even during food intake (FIGS. 1 and 2), sterile air membranes were created in the mouth and eyes to prevent virus access, and infection by breathing was minimized by breathing with sterile air from the nose.

Description

Positive pressure mask device for protection against coronavirus infection {CPAP mask device for protection against coronavirus infection}

Looking at the recently updated transmission route of coronavirus 19 (Covid 19), it is known that direct contact between people and Covid 19 particles in the secretions of the mouth, eyes and nose are transmitted by respiratory and sneezing droplets. Contact infection can be prevented by distancing and using a Covid 19 disinfectant, but droplet infection is prevented from spreading by wearing a virus-blocking mask that filters out virus particles from fine water particles or secretions containing Covid-19 particles in the air. is not complete In particular, it is difficult to completely block transmission because the mask must be removed when drinking or eating.

Medical personnel or medical workers treating patients infected with Covid 19 completely block the transmission of Covid 19 by wearing protective clothing that covers the entire body and breathes with air that has passed through a sterile filter. In addition, by creating a decompression ward, patients are being treated while preventing the spread of Covid-19 particles emitted by patients outside the ward.

Here, in hospitalizing and treating Covid 19 carriers or patients, an important key to blocking transmission is missing. In other words, the body parts where Covid 19 particles are emitted into the air are mostly through the mouth, nose and eyes, and feces, urine and pores of the skin can be considered. However, infection by the latter has not been reported (WHO, Q&A on corona viruses). Therefore, the fundamental prevention of transmission of Covid-19 particles is to block the entry of virus particles through the mouth, nose, and eyes in healthy people, and at the same time, to block the release of Covid-19 particles into the air in the case of Covid-19 carriers or patients, so that they can be transmitted to others as much as possible. It is to provide and maintain an air environment free of virus particles.

The inhaled air used for breathing passes through a virus-sterile filter and is supplied to the nose and mouth in a state without Covid-19 particles, and the exhaled air passes through a filter and releases it into the atmosphere. is prevented from entering the body, and the infected person (patient) completely blocks the emission of virus particles from the breath into the air. In particular, when wearing an existing mask, you must take off the mask when eating and drinking, and at this time, your mouth and nose are exposed to Covid 19 particles. We want to provide a mask that prevents infection as much as possible even when eating

The positive pressure mask device used in this project consists of a sterile air blower (Fig. 4), a nose and mouth mask (Figs. 1 and 2), and a sterile air discharger (Fig. 4) that sends air filtered out of Covid 19 particles to the mask. , they are connected by a hose. Here, the positive pressure mask is composed of a nose mask (11 in Figs. 1 and 2) and a mouth mask (12 in Figs. 1 and 2). It is supplied as inhalation of mouth breathing through the aseptic air injection hole (Fig. 2, 17) arranged at the bottom of the nose mask. Mouth breathing exhalation (in the case of patients containing Covid-19 particles) enters the inner mask (FIG. 3) through the one-way valve 25-1 of the mouth exhalation pipe 23, and exhalation discharge pipe 14 along with nasal exhalation It has a structure that emits after filtering through. At the top of the nose mask, aseptic air eye injection holes are arranged to form a protective film by aseptic air injection.

The present invention prevents virus infection by providing safe inhalation by always supplying aseptic air around the nose and mouth, and blocks mixing with inhalation by compartmentalizing the inside of the nose mask to minimize the amount of exhalation (virus contamination in the patient) and filter immediately. It is characterized by a structure that emits aseptic air and forms a sterile air film over the eyes and mouth through aseptic air injection holes to minimize infection even when eating food.

When ingesting food, separate the connection part of the mouth mask from the nose mask and peel it off with the chin (FIG. 2) and block the inner mask fixing hole 18 with a cover to block the inflow of outside air and allow food to be consumed through the mouth. Breathing can be done with sterile air in an inner nasal mask (FIG. 3). When the mouth mask is separated, small holes of a certain size at the bottom of the nose mask are sprayed to the front of the mouth through aseptic air injection holes arranged along the length of the mouth to form a sterile air film to prevent the access of Covid 19 particles in the air to the mouth. After eating, open the hole cover and combine the mouth mask 12 to the nose mask 11 (FIG. 1). In addition, air holes are arranged near the eyes at the top of the nose mask to form a sterile air film around the eyes to block the infection of the eyes by Covid-19 particles.

1. Air from which Covid 19 particles have been removed is provided to breathing (inhalation) at positive pressure by a blower equipped with a sterile filter (Fig. 4) to block respiratory infections through the nose and mouth, and breathe comfortably without mask inhalation resistance.

2. When eating or drinking, the mouth mask is separated from the nose mask and peeled off (Fig. 2) so that food can be consumed with the exposed mouth, and at the same time, within the nose mask, the virus infection is prevented by breathing with air from which Covid 19 particles have been removed. . While eating food, aseptic air is sprayed from the lower part of the nose mask (Fig. 2) to form an air film to minimize the infection of Covid 19 particles entering the mouth as much as possible. After eating, when the mouth mask is raised and combined with the nose mask, aseptic air is used for mouth breathing, and exhaled air is discharged into the atmosphere through the exhaust air filter (FIG. 4, 48).

3. Minimize eye infections by forming a film with aseptic air sprayed around the eyes from the primary nose mask.

4. In the case of Covid 19 patients, the exhaled breath from breathing is connected to the suction part of the aseptic air blower (Figs. 4 and 49) through the exhalation discharge pipe 14, and is discharged under reduced pressure to provide a virus-free air environment to others.

1 is a perspective view of a positive pressure mask supplied with sterile air through a tube. This mask has a structure connected by a nose mask 11 and a mouth mask 12 covering the nose and mouth, and the mouth mask is made of a flexible material that can be opened and closed by holding the ring 12-1. Since the nose mask must maintain a constant shape on the nose shape and supply aseptic air sent by the blower (air pump, FIG. 4) through the inhalation supply pipe 15 to the nose, non-toxic silicone, synthetic resin, polypropylene, etc. It is made of a structure that needs to be supported by a certain space and is in close contact with the skin when worn on the ear with the mask ear loop (13) so that there is no air leakage.
2 shows an open state of the mouth mask 12 (when food is consumed). It is a structure in which holes 17 of a certain size are arranged at the bottom of the nose mask (FIG. 2, 11) according to the size of the mouth. When sterile air in the nose mask is sprayed toward the mouth, a sterile air film is created and corona 19 particles in the air are blown into the mouth. By minimizing the access of food, it is possible to consume food more safely. Upon opening, the inner mask fixing hole 18 is immediately blocked with a hole cover 19 to prevent external contaminated air from entering the inner nose mask. The eye part prevents virus eye infection by creating a sterile air film through the sterile air injection hole 16. After eating, the hole cover is opened and the mouth mask is lifted and closed.
3 is a perspective view of another inner nasal mask 21 in the space within the nasal mask 11. This minimizes mixing of inhalation and exhalation by preventing the inhalation one-way valve 21 in the nose mask 11 from flowing backward to the nose mask. In the case of corona infected patients, the contaminated exhaled breath is compartmentalized into the inner nasal mask, so that all of them are sent to the exhalation discharge pipe 14 to efficiently filter out virus particles through the exhaust filter (Figs. 4 and 48) to release only sterile air. has a structure that
4 is an exemplary view of a power blower equipped with a sterile air filter used in the present invention (40). This blower consists of a control box 44 that controls power supply and mechanical operation, a power blower 49, and inhalation and exhalation filter spaces 42 and 48 that filter virus particles, and a one-way valve ( 45, 45-1) is installed to prevent backflow, and through the inhalation and exhalation tubes connected to the mask, sterile air is sent to the nose mask by inhalation and exhalation is received and passed through a filter to release sterile air into the atmosphere. .

1. The present invention is a positive pressure mask composed of a sterile air blower (Fig. 4) that sends sterile air filtered out of Covid 19 particles to an inhalation nose mask, a nose mask (11) and a mouth mask (Figs. 1 and 2) that can be opened and closed. They are connected by a hose.

2. When this positive pressure mask is worn and the device is operated, the sterile air blower (Fig. 4) continuously supplies sterile air to the nose mask through the sterile inhalation pipe (15 in Figs. 1 and 2). ) through which air is sprayed to form a sterile air film to block the access of virus particles to the eyes.

3. In the case of mouth breathing, aseptic air injected through the mouth injection holes (Figs. 2 and 17) at the bottom of the nose mask is used as inhalation of mouth breathing, and exhalation from the mouth enters through the inner mask hole (Figs. 2 and 18). It is discharged to the exhalation discharge pipe (14).

4. Sterile air used for nasal breathing is supplied to the nose through the inhalation one-way valve 25 by installing another internal nasal mask (FIG. 3) inside the nasal mask to create a structure with a new compartment. The exhaled breath from the nose breathing is blocked by the suction one-way valve (Figs. 3, 24, and 25) to block the back flow to the mouth and nose mask, and flows only in the direction of the exhalation discharge pipe (14) and passes through the exhaust filter (Fig. 4, 43). Only sterile air is released into the atmosphere.

5. When the mouth mask is opened for food intake (FIG. 2), aseptic air is sprayed from the injection holes 17 of the nose mask arranged around the mouth to form a sterile air film to minimize viral infection in the mouth. By using aseptic air in the room, it is possible to minimize viral transmission by breathing.
