Description

Disinfection mask

Technical Field

The invention belongs to the field of respiratory protection devices, and particularly relates to a disinfection mask which is characterized by not only protecting a user from being damaged by external pathogens, but also killing exhaust gas exhaled by the user to prevent the pathogens from entering air to be transmitted, and has different functions compared with the commonly used gas masks, masks and the like.

Background

Respiratory infectious diseases (such as Severe Acute Respiratory Syndrome (SARS) and novel coronavirus pneumonia (COVID-19)) are a group of infectious diseases with relatively high transmission speed, and are mainly characterized in that pathogens are latent, live and propagate in the respiratory tract, then spread into the air through droplets formed by coughing and sneezing, and then inhaled into the respiratory tract by other people to realize the spread of the pathogens, namely, the main transmission path of the respiratory infectious diseases is the droplets. Of course, respiratory infections can also be transmitted by other means, such as contact transmission, fecal oral transmission, eyelid transmission, etc., but airborne transmission is the primary route of respiratory infections.

In the prevention and control process, if healthy people can isolate various pathogens in the air and inhale clean air, infection of such infectious diseases can be effectively prevented, and therefore, the basic method for preventing and treating respiratory infectious diseases is to isolate pathogens in the air. The isolation method which is most used at present is to wear a mask, and the mask is used for isolating pathogen infection between people, so that the isolation method is a simple and effective method. There are many kinds of masks, for example, N95 masks, dust masks, activated carbon medical masks, surgical masks, and plain paper masks. The core function of the mask is to isolate pathogens, which in the case of healthy persons isolates external pathogens from transmission to the interior of the individual, and in the case of patients prevents transmission of pathogens to the exterior.

However, although the mask has a remarkable barrier effect, the following problems still remain:

1) the using effect is not equal to the theoretical effect, the theoretical protective effect of the mask is determined according to the structure and the material performance of the mask, but in the actual using process, the protective performance of the mask can be greatly reduced if a user uses the mask improperly, and the using effect is related to the using time. For example, large gaps may occur when the mask straps are loose, or the user sneezes, coughs, or uses for extended periods of time, which can cause infection by pathogens.

2) The mask has no effect of killing pathogens, only plays a role of isolation and cannot kill the pathogens, so that although the mask has a protection effect on healthy people, the pathogens in the body of a patient are not killed, and once the pathogens leak through the mask, the pathogens are also harmful.

3) This is detrimental to the patient himself, as the patient uses the mask, the impact on others can be reduced or eliminated, but due to the barrier effect, pathogens will stay in the patient's respiratory tract, which, although may be low relative to the number of pathogens in the body, is still harmful to the patient. For example, with regard to new types of coronavirus and SARS virus, wearing a mask may fill the entire lung of a patient with the virus, so that the virus is rapidly adsorbed to the entire lung, causing a large area infection in the lung of the patient, thereby easily causing a large outbreak, which endangers the life of the patient.

In addition, the gas mask is a method for effectively isolating pathogens in the air, and its emphasis is to prevent external toxic gas from entering the inside of the human body and to provide nontoxic gas to the human body, but it can kill pathogens in only a part of the air entering the human body. Therefore, there is a need in the art for improvements to masks, gas masks, and the like that not only provide isolation from pathogens, but more importantly, provide kill.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, an embodiment of the present invention provides a sterilizing mask including a face mask which is worn on a user's head and has a size and a shape corresponding to the user's face, and a sterilizing chamber which is connected to the face mask and is used to sterilize and sterilize the air exhaled from the user and then discharge clean air.

The details of each component are described below one by one.

As shown in fig. 1 to 4, the mask includes a mask body 101 and mask bands 103 provided on both sides of the mask body 101, wherein the mask body 101 serves to isolate inner and outer spaces, may be made of plastic, and has a shape matching the structure of the face below the eyes of a person, particularly a mask rim portion, and leaves a certain inner space between the mask body and the nose and mouth of the person, similar to a mask. The straps 103 are used to secure the mask to the user's ears and are made of elastic cord, or non-elastic cord may be used.

Specifically, the cover body 101 is provided with a one-way air inlet 201 and a one-way air outlet 202, both the one-way air inlet 201 and the one-way air outlet 202 have one-way opening functions, the one-way air inlet 201 is opened when a user inhales air and is closed when exhaling air, and the one-way air outlet 202 is opened when the user exhales air and is closed when inhaling air.

For convenience of processing, as shown in fig. 2 and 3, the one-way air inlet 201 and the one-way air outlet 202 are integrated into one breathing head 203, that is, the breathing head 203 is directly provided with the one-way air inlet 201 and the one-way air outlet 202, although the one-way air inlet 201 and the one-way air outlet 202 can be processed independently, the processing process is complicated.

In the present invention, it is preferable to realize the one-way opening function of the one-way air inlet 201 and the one-way air outlet 202 by using a one-way valve. Of course, other structures capable of realizing the one-way opening function may be adopted, which is not described herein. As shown in fig. 3, an intake check valve 303 is provided in the one-way intake port 201, an exhaust check valve 302 is provided in the one-way exhaust port 202, and the intake check valve 303 and the exhaust check valve 302 have the same structure.

As shown in fig. 4, each of the suction check valve 303 and the discharge check valve 302 includes a valve plate 401, a spring 402, and a valve body 404 having a through hole, and the valve plate 401 is mounted on the valve body 404, for example, by a steel wire 403, for closing the through hole of the valve body. Specifically, one end of the steel wire 403 is connected to the valve plate 401, and the other end is connected to the upper end of the valve body 404, so that the valve plate 401 does not deviate from the through hole of the valve body 404 when opening and closing. One end of the spring 402 is connected with the valve plate 401, and the other end is connected with the inner wall of the through hole of the valve body 404, and is used for tensioning the valve plate to tightly seal the through hole of the valve body, and when the valve plate is not used, the air suction check valve 303 and the air exhaust check valve 302 are both in a closed state (namely the valve plate seals the through hole of the valve body). During assembly, the check valve is embedded in the one-way exhaust port and the one-way air suction port according to actual needs, as shown in fig. 3, the air suction check valve is installed in the one-way air suction port in an installation mode that the valve body faces upwards and the valve plate faces downwards, and the exhaust check valve is installed in the one-way exhaust port in an installation mode that the valve body faces downwards and the valve plate faces upwards.

The working process of the air suction one-way valve and the air exhaust one-way valve is briefly explained below, when the mask is not used, the air suction one-way valve 303 and the air exhaust one-way valve 302 are both in a closed state, when a user uses the disinfection mask, the air suction one-way valve 303 is opened due to the difference between internal pressure and external pressure during air suction, external air enters the mask through the air suction port, when the user exhales, the air suction port is closed by the valve sheet of the air suction one-way valve 303 under the action of air flow and a spring, the valve sheet of the air exhaust one-way valve 302 is opened under the action of the difference between internal pressure and external pressure, exhaled waste gas is exhausted into the killing box through the air exhaust port, when the user inhales again, the air exhaust port is closed by the valve sheet of the air exhaust one-way valve. The reciprocating motion realizes that the one-way air inlet 201 is opened when the user inhales and closed when exhales, and the one-way air outlet 202 is opened when the user exhales and closed when inhales.

In order to prevent the polluted air from being sucked, the one-way air suction port 201 is sleeved with an air suction cover 304, a filter screen is arranged on the air suction cover 304 to filter the air sucked by a user, only a filter membrane on the filter screen can be replaced, and other components can be reused.

To improve comfort, avoid damage to the skin by the mask, and improve the sealing of the mask, a sealing ring 102 is provided on the rim of the mask body 101. The sealing ring 102 is made of elastic soft cloth and the like, has a certain width, and can be tightened to a certain extent after being worn by a user, so that the sealing performance of the mask is ensured.

As shown in fig. 1, the killing case includes a case body 111, an exhaust pipe 113 and an exhaust pipe 109, the case body 111 is used for storing the killing solution 112, the case body 111 is made of a corrosion-resistant material, a material which is as soft as possible is used to ensure the comfort of a user, and the killing case should be lower than the lower end of the mask when in use. The killing solution 112 is a solution for killing pathogens, and may be, for example, medical alcohol, strong acid, or the like. The addition height of the killing solution is not more than one third of the height of the box body.

Specifically, the exhaust pipe 113 is made of a corrosion-resistant material with a large pipe diameter, is arranged inside the box body 111 and is designed to prevent backflow, and the killing solution in the killing box is prevented from flowing back to the one-way exhaust port through the exhaust pipe, so that a user is prevented from being injured. The inlet of the exhaust pipe 113 is connected to the one-way exhaust port 202, specifically, the pipe joint 104 is connected to the exhaust pipe 105, and then the pipe joint 104 is connected to the one-way exhaust port 202, the pipe joint 105 is used for conveying the exhaust gas exhaled by the user, only a common plastic hose is used, but the connection part with the killing box preferably has a certain corrosion resistance, and the corrosion damage of the killing solution to the pipe joint is prevented. The outlet of the waste gas line 113 is located in a sterilizing solution for sterilizing the gas exhaled by the user. The exhaust pipe 109 is also disposed inside the box 111, but does not contact the killing solution, so as to exhaust the sterilized clean gas in the box 111.

Preferably, the exhaust pipe 113 is designed to prevent backflow as follows: the exhaust pipe 113 is designed in a shape of a Chinese character 'hui', an inlet and an outlet of the exhaust pipe are both located at the bottom of the box 111, the outlet faces the bottom of the box, and a pipe body of the exhaust pipe extends upwards from the inlet and reaches the outlet after surrounding a circle along the inner wall of the box 111, so that the gas exhaled by the user is conveyed from the bottom of the box 111 to the top of the box 111 through the inlet and then conveyed to the bottom of the box 111, and is discharged into the killing solution through the outlet, and the killing solution is prevented from flowing back through the exhaust pipe 113.

Further preferably, in order to further enhance the backflow prevention effect, a portion of the pipe body located at the top of the box body 111 is designed to be spiral or serpentine, and a portion of the pipe body near the outlet is designed to be spiral or serpentine.

The gas that the user exhaled gets into the back from the bottom of box, rises to the top along the tank wall, walks spiral or snakelike at the top, then goes to the bottom of the case along the tank wall down, also walks spiral or snakelike at the bottom, discharges through the opening part in the middle of the bottom of the box again, then rises from killing solution, and the blast pipe that gets into the case of killing at last discharges.

Since the exhaust pipe has a longer portion immersed in the killing solution, the gas flow path is longer and the killing action time is longer. Because the outlet of the waste gas pipe is arranged at the bottom of the box body and faces the direction of the bottom, no matter how the box body is placed, the killing solution always exists in a certain section of the waste gas pipe, and the condition that waste gas is directly discharged is avoided.

In addition, the length of the exhaust pipe mainly takes into account the following three issues: firstly, the comfort of the user is realized, and the user can not feel strenuous when using the mask, and the mask is slightly stronger than normal breathing; secondly, the killing capacity of the killing solution is higher, the pipeline is shorter; and thirdly, the box body is closed, and when the box body is positioned at any position, a completely closed path always exists in the exhaust gas pipe, so that the exhaust gas cannot be directly discharged into the outer space. The specific length design may be designed by combining the above factors according to actual conditions, which is not described herein.

Specifically, blast pipe 109 can adopt the great corrosion-resistant material of pipe diameter to make, and its both ends design is the straight tube, and the interlude design is the spiral, and each section has decurrent gradient promptly, and when being convenient for add the solution of killing from blast pipe department, the solution of killing can all flow to the bottom of box automatically. The outlet end of the exhaust pipe 109 extends from the top of the box 111, a drain pipe 108 is sleeved outside the outlet end, a killing solution channel is formed by the inner wall surface of the drain pipe 108 and the outer wall surface of the exhaust pipe 109, the drain pipe 108 is communicated with the inside of the box, so that the used killing solution can be poured out through the killing solution channel, and the addition of the killing solution is performed through the exhaust pipe 109.

Further, a closing cap 107 is mounted on the drain pipe 108 for closing the drain pipe 108 to prevent the sterilizing solution from leaking. This closing cap 107's middle part switches on with blast pipe 109, closing cap 107 middle part exit has still designed dust screen 106, can add and change the solution of killing through fluid-discharge tube 108 when the closing cap is unscrewed, when the closing cap was screwed up, seal fluid-discharge tube 108 on the one hand (the passageway that the fluid-discharge tube internal face formed with the blast pipe outer wall face promptly is sealed, this passageway is independent each other with the blast pipe, non-conductive), on the other hand intercommunication blast pipe for clean gas after the disinfection is in proper order through the blast pipe, the middle part of closing cap and dust screen discharge box. The dust screen 106 prevents dust from entering the tank and also prevents the killing solution from leaking.

Furthermore, the lower end of the exhaust pipe 109 is located at one-half of the height of the box body, when the box body is inverted, the lower end of the exhaust pipe 109 is located above the killing solution, the killing solution cannot flow into the exhaust pipe, and the adding height of the killing solution is not more than one-third of the height of the box body, so that the killing solution cannot enter the exhaust pipe when the box body rotates randomly, no matter how the killing box is placed, the killing solution cannot leak from any position, and a user can do any movement when using the disinfecting mask as long as the killing box is not higher than the air outlet of the mask, and the disinfecting mask has high portability.

In order to be convenient for a user to carry about, the box body 111 is provided with two lifting lugs 110 on the left and right for fixing the lifting rope, so that the killing box is convenient for the user to carry about.

The working principle of the disinfection mask is as follows:

after the user wears the disinfection mask, send into the case that kills through the connecting pipe with internal waste gas during expiration, kill solution in the case through killing and carry out the deactivation in twinkling of an eye, then the blast pipe in the rethread is killed the case and discharges gas to the exterior space. When the mask inhales air, the air outside is inhaled through the one-way air inlet on the mask, and the inhaled air is filtered through the filter screen on the air suction port, so that external pathogens are prevented from entering the body of a user.

The killing solution can be added or replaced by opening the closing cover, the killing solution can be directly added from the liquid discharge pipe when being added, the killing box is inverted when being replaced, and the killing solution flows out from the side wall of the liquid discharge pipe. The pipe orifice of the liquid discharge pipe is tightly sealed when the sealing cover is screwed, so that the solution is prevented from leaking. When adding the solution, the exhaust check valve on the mask can be opened in order to ensure that the solution enters the exhaust pipe.

The disinfecting mask is mainly used for protecting respiratory infectious diseases, can be used in various occasions, and is particularly suitable for healthy people, asymptomatic patients and mild patients. For example, a disinfecting mask may be used in the following situations: activities in public places, such as movie theaters, conference rooms, can be provided with disinfecting masks for everyone when entering public places, so that the public places are not contaminated by pathogens brought by the participants. The hospital, no matter disease or accompanying person all wears the disinfection mask, so not only can the safety of the healthy personnel be protected, but also the concentration of pathogens in the hospital can be greatly reduced.

Of course, the method can also be applied to other various occasions needing isolating and killing pathogens. The killing of pathogens is performed by a killing solution in a killing tank. Such killing requires a transient nature, i.e. the killing rate of the pathogens should be close to 100% when the exhaust gases are discharged from the killing solution, and also requires a safety, i.e. protection against accidental injury to the user, so that the killing solution must be safe and effective. Since the safety requirements are different for different applications, a plurality of kill tanks may be provided. For example, medical alcohol may be used in a place with a large space, and strong acid, strong alkali, or the like may be used in a place with little exercise. In fact, if the killing box is not higher than the lower end of the face mask, the backflow phenomenon can not occur, so that strong acid, strong alkali and other strong effective killing solutions can be used in most occasions.

The mask is recommended to be used continuously, water and diet can be taken during the use period, but the total use time is as short as 10-12 hours at least to cover the virus reproduction period, and the effect is better. The disinfection mask designed by the invention can prevent a user from inhaling the air containing pathogens outside through breathing, and meanwhile, can disinfect the air exhaled by the user, and prevent the air with viruses from being directly exhausted to the external space. Different from the traditional mask in function, the mask mainly kills pathogens in a user body and ensures that outside air is not polluted, thereby effectively blocking the transmission of the pathogens.

The focus of the present invention is on the killing of pathogens in infected individuals and the quarantine protection of healthy individuals. For infected persons, the exhaled toxic gas needs to be killed, the pollution of the toxic gas to the external air is prevented, meanwhile, the concentration of pathogens in the respiratory tract space of the patient can be effectively reduced, the infection of the pathogens on the uninfected organism in the patient is avoided, the number of the pathogens which are transmitted from one part of the lung to another part which is not adjacent to the lung through the air is reduced, and therefore the patient has a certain pathogen inhibition effect.

For healthy people, although ordinary masks have a strong isolation effect against fine particles such as droplets, pathogens floating in the air can still enter the body through the edges of the masks and the like because high sealing performance cannot be achieved. The mask is a passive protective measure, and infection can be avoided only by strictly following the operating regulations in the using process. The invention can increase the sealing performance of the disinfection mask, so that the breathing of the protected person can be only carried out through the inlet and the outlet of the disinfection mask, and on the other hand, the disinfection mask has the effect of killing the gas exhaled by the patient and purifies the outside air, so that the concentration of pathogens in the outside air can be controlled in a very low range, even in a zero-pathogen state, and the outside air is filtered by the filter screen when entering the healthy person through the disinfection mask, so that the pathogens inhaled by the user are extremely rare, and the healthy person is effectively protected from infection.

The invention is an active prevention and cure measure, which is not only capable of isolating pathogens, but also capable of actively killing pathogens and keeping the outside air clean, and has very obvious prevention and cure effect. If a person wears the disinfection mask during the epidemic situation, the disinfection mask can not only protect healthy people, but also prevent and control infected people, and more importantly, has a positive effect on the drug carriers which cannot be found in medical examination (namely, patients without symptoms such as fever and cough), and prevents the potential harm of the drug carriers to the healthy people. The invention not only has the disinfection function, but also has the function of helping the user to breathe deeply, and the invention can effectively promote the user to breathe deeply and reduce the adsorption of virus in human body by completely depending on the autonomous respiration of the user.

The design scheme provided by the invention can effectively block the pathogen release of the patient to the external space, protect the external air, has a certain treatment effect on the patient, particularly has a positive effect on the mild patient or the asymptomatic patient, effectively protects the healthy person, and blocks the pathogen from being inhaled into the body of the healthy person through inhalation. If the disinfection mask is used by both mild and suspected persons in public places, the healthy persons can even not use the disinfection mask or only use a common medical mask. For example, when a person enters a public place, a sterile mask is dispensed to each person to ensure that everyone is not infected. Because the polluted parts of the designed equipment which need to be replaced are only the air inlet filter screen, the disinfectant, the mask and other parts on the mask which can be directly cleaned by the disinfectant, a user can repeatedly use the equipment, so that the use cost can be greatly reduced, and the invention has greater economic benefit.

The present invention is specifically designed to accommodate the manufacture of sterile mask products in general. It will be apparent to one of ordinary skill in the art that the product structure, material selection, and manufacturing method of the present invention can be implemented in a general manufacturing facility, for example, any manufacturing facility such as a medical device manufacturing facility, a plastic product manufacturing facility, and the like.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
