Description

a disinfectant mask

technical field

The invention belongs to the field of respiratory protection devices, and more particularly, relates to a disinfection mask, which is characterized in that it can not only protect the user from external pathogens, but also kill the exhaust gas exhaled by the user to prevent pathogens from entering the air. It is different from the commonly used gas masks, masks and other functions.

Background technique

Respiratory infectious diseases (such as severe acute respiratory syndrome (SARS), novel coronavirus pneumonia (COVID-19)) are a class of infectious diseases that spread rapidly, and their main feature is that pathogens lurk, survive and multiply in the respiratory tract , and then form droplets into the air through coughing and sneezing, and then be inhaled into the respiratory tract by others to achieve the spread of pathogens, that is, the main transmission route of respiratory infectious diseases is droplets. Of course, respiratory infectious diseases can also be transmitted in other ways, such as contact transmission, fecal-oral transmission, eyelid transmission, etc., but airborne transmission is the main way of respiratory infectious diseases.

In the process of prevention and control, if healthy personnel can isolate various pathogens in the air and inhale clean air, they can effectively prevent infection of such infectious diseases. Therefore, the basic method of preventing and treating respiratory infectious diseases is to isolate pathogens in the air. . At present, the most widely used isolation method is to wear a mask, which is a simple and effective method to isolate pathogen infection between people. There are many types of masks, such as N95 masks, dust masks, activated carbon medical masks, surgical masks and plain paper masks. The core function of the mask is to isolate pathogens. For healthy people, it isolates the transmission of external pathogens to the inside of the individual, and for patients, it avoids the transmission of pathogens to the outside.

However, although the isolation effect of masks is obvious, there are still the following problems:

1) The use effect is not the same as the theoretical effect. The theoretical protective effect of the mask is determined by the structure and material properties of the mask itself, but in the actual use process, improper use by the user may greatly reduce the protective performance of the mask, and the use effect It also depends on the usage time. For example, when the mask strap is loose, there may be large gaps, or the user sneezes, coughs, or uses it for a long time, which can cause pathogen infection.

2) There is no killing effect on pathogens. The mask only plays a role in isolation and cannot kill pathogens. Although it has a protective effect on healthy personnel, the pathogens in the patient's body have not been killed. Once leaked through the mask, it will also cause harm.

3) It is not good for the patient itself. When the patient uses a mask, the impact on others can be reduced or eliminated, but due to the isolation effect, the pathogen will stay in the patient's respiratory tract, although it may be relatively low relative to the number of pathogens in the body, but still harmful to the patient. For example, for the new coronavirus and SARS virus, wearing a mask may fill the entire lung of the patient with the virus, so that the virus will be quickly absorbed in all the lungs, causing a large area of the patient's lungs to be infected, which is prone to large outbreaks, endangering patient's life.

In addition, the gas mask is also a method that can effectively isolate pathogens in the air, and its focus is to prevent the external toxic gas from entering the inside of the human body and provide the human body with non-toxic gas, but it can only protect part of the air that enters the human body. pathogens in it. Therefore, there is an urgent need in the art to improve masks, gas masks, etc., so that they not only have the effect of isolating pathogens, but more importantly, they have the effect of killing.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can 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 disinfection mask, which includes a mask and a killing box, wherein the mask is worn on the user's head, and its size and shape are adapted to the user's face, and the killing box and the mask It is used to sterilize and sterilize the gas exhaled by the user to discharge clean gas.

Each component will be described in detail below.

As shown in Figures 1-4, the mask includes a cover body 101 and cover straps 103 arranged on both sides of the cover body 101, wherein the cover body 101 is used to isolate the inner and outer space, and can be made of plastic with a shape similar to that below the human eye. The facial structure should be matched, especially the edge of the mask should match, and there should be a certain internal space between the mask body and the person's mouth and nose, similar to a mask. The straps 103 are used to secure the mask to the user's ears, and are made of elastic cords, but non-elastic cords can also be used.

Specifically, the cover body 101 is provided with a one-way intake port 201 and a one-way exhaust port 202. Both the one-way intake port 201 and the one-way exhaust port 202 have a one-way opening function. The one-way exhaust port 202 opens when the user inhales and closes when the user exhales. The one-way exhaust port 202 opens when the user exhales and closes when the user inhales.

For the convenience of processing, as shown in FIGS. 2 and 3 , the one-way suction port 201 and the one-way exhaust port 202 are integrated into one breathing head 203 , that is, the one-way suction port 201 is directly opened on the breathing head 203 . And the one-way exhaust port 202, of course, the one-way suction port 201 and the one-way exhaust port 202 can also be processed independently, but the processing process will be cumbersome.

In the present invention, a one-way valve is preferably used to realize the one-way opening function of the one-way intake port 201 and the one-way exhaust port 202 . Of course, other structures capable of realizing the one-way opening function can also be adopted, and details are not described here. As shown in FIG. 3, an intake check valve 303 is provided in the one-way intake port 201, an exhaust check valve 302, an intake check valve 303 and an exhaust check valve are provided in the one-way exhaust port 202 302 has the same structure.

As shown in FIG. 4 , the suction check valve 303 and the exhaust check valve 302 both include a valve plate 401, a spring 402 and a valve body 404 with a through hole. The valve plate 401 is installed on the valve body 404 through a steel wire 403, for example, Used to close 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 position of the valve body 404 when opening and closing. One end of the spring 402 is connected to the valve plate 401, and the other end is connected to the inner wall of the through hole of the valve body 404, which is used to tighten the valve plate to close the valve body through hole tightly. The one-way valves 302 are all in a closed state (ie, the valve plate closes the through hole of the valve body). During assembly, the above one-way valve is embedded in the one-way exhaust port and one-way suction port according to the actual needs, as shown in Figure 3, the suction one-way is installed with the valve body facing up and the valve plate facing down. The valve is installed in the one-way suction port, and the exhaust check valve is installed in the one-way exhaust port with the valve body facing down and the valve plate facing up.

The working process of the suction check valve and the exhaust check valve will be briefly described below. When not in use, the suction check valve 303 and the exhaust check valve 302 are both closed. , when inhaling, the inhalation one-way valve 303 is opened due to the internal and external pressure difference, and the external air enters the mask through the inhalation port. The valve plate of the exhaust one-way valve 302 is opened under the action of the internal and external pressure difference, so that the exhaled exhaust gas is discharged into the killing box through the exhaust port, and the valve plate of the exhaust one-way valve 302 is exhausted when inhaling again. Under the action of the air flow and the spring, the exhaust port is closed, the inhalation check valve 303 is opened due to the pressure difference between the inside and outside, and the outside air enters the mask through the intake port. In this way, the one-way inhalation port 201 opens when the user inhales and closes when the user exhales, and the one-way exhaust port 202 opens when the user exhales and closes when the user inhales.

In order to prevent the inhalation of polluted air, a suction cover 304 is set on the one-way suction port 201. The suction cover 304 is provided with a filter screen to filter the air inhaled by the user, and only the filter membrane on the filter screen can be replaced. , other parts can be reused.

In order to improve comfort, prevent the mask from damaging the skin, and at the same time improve the sealing performance of the mask, a sealing ring 102 is provided on the edge of the cover body 101 . The sealing ring 102 is made of materials such as elastic soft cloth, and has a certain width, so that the user can have a certain tightening range after wearing, so as to ensure the sealing performance of the mask.

As shown in FIG. 1 , the killing box includes a box body 111, an exhaust pipe 113 and an exhaust pipe 109. The box body 111 is used to store the killing solution 112. The box body 111 is made of corrosion-resistant materials, and soft materials are used as much as possible. , to ensure the user's comfort, the killing box should be lower than the lower end of the mask when used. The killing solution 112 is a solution for killing pathogens, such as medical alcohol, strong acid and the like. The addition height of the killing solution should not exceed one third of the height of the box.

Specifically, the waste gas pipe 113 is made of a corrosion-resistant material with a larger diameter, which is arranged inside the box body 111 and is designed to prevent backflow to prevent the killing solution in the killing box from flowing back to the one-way through the waste gas pipe. into the exhaust port, thereby injuring the user. The inlet of the exhaust pipe 113 is connected to the one-way exhaust port 202, specifically, the connecting pipe 105 is firstly connected to the pipe joint 104, and then connected to the one-way exhaust port 202 through the pipe joint 104. The connecting pipe 105 is used for conveying the exhaled air of the user. For waste gas, ordinary plastic hoses can be used, but the connection part with the killing box should preferably have a certain corrosion resistance to prevent the corrosion and damage of the connecting pipe by the killing solution. The outlet of the exhaust pipe 113 is located in the killing solution, which is used for sterilizing the gas exhaled by the user. The exhaust pipe 109 is also arranged inside the box body 111 , but is not in contact with the killing solution, so as to facilitate the discharge of the sterilized clean gas in the box body 111 .

Preferably, the waste gas pipe 113 is designed to prevent backflow as follows: the waste gas pipe 113 is designed in a back-shaped shape, its inlet and outlet are located at the bottom of the box body 111, and the outlet faces the bottom of the box body, and its tube body extends upward from the inlet and It goes around the inner wall of the box body 111 and then reaches the outlet, so that the gas exhaled by the user is transported from the bottom of the box body 111 to the top of the box body 111 and then to the bottom of the box body 111, and is discharged from the outlet to the sterilization solution, and prevent the killing solution from flowing back through the exhaust pipe 113.

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

After the gas exhaled by the user enters from the bottom of the box, it rises to the top along the box wall, takes a spiral or serpentine shape at the top, and then descends along the box wall to the bottom of the box, and also takes a spiral or serpentine shape at the bottom, and then from the bottom of the box. The bottom of the box is discharged through the opening in the middle, then rises from the killing solution, and finally enters the exhaust pipe of the killing box to discharge.

Because a longer part of the waste gas pipe is immersed in the killing solution, the gas flow is longer and the killing time is longer. Since the outlet of the exhaust pipe is located at the bottom of the box and faces the bottom direction, no matter how the box is placed, there is always a killing solution in a certain section of the exhaust pipe, which will not cause the direct discharge of exhaust gas.

In addition, the length of the exhaust pipe mainly considers the following three issues: First, the comfort of the user, even if it is not strenuous during use, it can be slightly stronger than normal breathing; second, the killing ability of the killing solution, the killing ability of the killing solution. The stronger the killing ability, the shorter the pipeline; the third is the closedness, when the box is in any position, there is always a completely closed section in the exhaust pipe, so that the exhaust gas cannot be directly discharged into the outer space. The specific length design can be designed according to the actual situation in combination with the above factors, which will not be repeated here.

Specifically, the exhaust pipe 109 can be made of a corrosion-resistant material with a larger diameter. The two ends of the exhaust pipe 109 are designed as straight pipes, and the middle section is designed as a spiral shape, that is, each section has a downward inclination, which is convenient for the exhaust pipe. When adding the killing solution, the killing solution can automatically flow to the bottom of the box. The outlet end of the exhaust pipe 109 protrudes from the top of the box body 111, and the outlet end is covered with a drain pipe 108. The inner wall of the drain pipe 108 and the outer wall of the exhaust pipe 109 form a killing solution channel. The drain pipe 108 communicates with the inside of the box, so that the used killing solution can be poured out through the killing solution channel, and the killing solution is added through the exhaust pipe 109 .

Further, a closing cover 107 is installed on the drain pipe 108 for closing the drain pipe 108 to prevent leakage of the killing solution. The middle of the closing cover 107 is connected to the exhaust pipe 109, and a dustproof net 106 is also designed at the outlet of the middle of the closing cover 107. When the closing cover is unscrewed, the killing solution can be added and replaced through the drain pipe 108. When the closing cover is tightened , on the one hand, the drainage pipe 108 is closed (that is, the channel formed by the inner wall of the drainage pipe and the outer wall of the exhaust pipe is closed, and the channel and the exhaust pipe are independent of each other and do not conduct), and on the other hand, the exhaust pipe is connected, so that the disinfection The clean gas after it is discharged from the box through the exhaust pipe, the middle of the closing cover and the dustproof net in turn. The dustproof net 106 can prevent dust from entering the box, and can also prevent the leakage of the killing solution.

Further, the lower end of the exhaust pipe 109 is located at half the height of the box body, the lower end of the exhaust pipe 109 is above the killing solution when the box body is inverted, and the killing solution will not flow into the exhaust pipe, and The addition height of the killing solution does not exceed one-third of the height of the box, so the killing solution cannot enter the exhaust pipe when the box is rotated at will. No matter how the killing box is placed, the killing solution cannot leak from any position. When using the disinfection mask, the user can do any exercise as long as the killing box is not higher than the air outlet of the mask, which has high portability.

In order to facilitate the user's carrying around, the box body 111 is provided with lifting ears 110, two on the left and right, for fixing the suspending rope, which is convenient for the user to carry the killing box.

The working principle of the disinfection mask of the present invention is as follows:

When the user puts on the disinfection mask, when exhaling, the waste gas in the body is sent into the killing box through the connecting pipe, and is instantly inactivated by the killing solution in the killing box, and then passes through the exhaust gas in the killing box. The gas pipe discharges the gas to the outside space. When inhaling, the external air is inhaled through the one-way air inlet on the mask, and the inhaled air is filtered through the filter on the inhalation port to prevent external pathogens from entering the user's body.

Open the closed cover to add or replace the killing solution. When adding the killing solution, it can be added directly from the drain pipe. When replacing, the killing box is inverted, and the killing solution flows out from the side wall of the drain pipe. When tightening the closure cap, seal the nozzle of the drain tube tightly to prevent the solution from leaking. When adding the solution, in order to ensure that the solution enters the exhaust pipe, you can press the exhaust one-way valve on the mask.

The disinfection mask of the invention is mainly used for the protection of respiratory infectious diseases, can be used in various occasions, and is especially suitable for healthy people, asymptomatic patients and mild patients. For example, sanitizing masks can be used in the following situations: activities in public places, when entering public places, such as movie theaters, conference rooms, everyone can be distributed with sanitizing masks, so that the public place will not be affected by the participants. Pathogen contamination. In hospitals, both patients and accompanying staff wear disinfection masks, which not only protects the safety of healthy personnel, but also greatly reduces the concentration of pathogens in the hospital.

Of course, it can also be applied to various other occasions where pathogens need to be isolated and killed. The killing of pathogens is carried out by the killing solution in the killing box. This killing needs to be instantaneous, that is, when the waste gas is discharged from the killing solution, the killing rate of pathogens should be close to 100%. At the same time, it is also necessary to ensure safety, that is, to prevent accidental injury to users, so the killing solution must be safe and effective. . Since the safety requirements of different use cases are different, multiple killing boxes can be equipped. For example, medical alcohol can be used in places with larger spaces, while strong acids and alkalis can be used in places with little exercise. In fact, if the killing box is not higher than the lower end of the mask, there will be no reflux phenomenon, so strong and effective killing solutions such as strong acid and strong alkali can be used in most occasions.

The disinfection mask of the present invention is recommended to be used continuously during use. During use, you can drink water and eat, but the total use time is at least 10-12 hours to cover the reproduction cycle of the virus, and the effect is better. The disinfection mask designed by the present invention can prevent the user from inhaling the air containing pathogens outside by breathing, and at the same time sterilize the gas exhaled by the user, preventing the air with viruses from being directly discharged to the external space. Different from the traditional mask function, its function focuses on killing pathogens in the user's body and ensuring that the outside air is not polluted, thereby effectively blocking the spread of pathogens.

The design of the present invention focuses on killing pathogens in infected persons and isolating and protecting healthy persons. For infected people, it is not only necessary to kill the toxic gas they exhale to prevent their pollution to the outside air, but also to effectively reduce the concentration of pathogens in the patient's respiratory space, avoid their infection to the uninfected body inside the patient, and reduce pathogens from The amount of airborne infection of one part of the lung to another part that is not adjacent, thus having a certain pathogen-suppressing effect on the patient.

For healthy people, although ordinary masks have a strong isolation effect on tiny particles such as droplets, it is impossible to achieve high sealing, so pathogens floating in the air can still enter the body through the edge of the mask and other parts . The use of masks is a passive protective measure, and infection can only be avoided if the operating procedures are strictly followed during use. On the one hand, the present invention can increase the sealing performance of the disinfection mask, so that the breathing of the protected person can only be carried out through the inlet and outlet of the disinfection mask; The concentration of pathogens in the outside air can be controlled in a very low range, or even zero pathogens. When the outside air enters the healthy body through the disinfection mask, it is filtered by the filter screen, so that the pathogens inhaled by the user are extremely rare. Effectively protect healthy people from infection.

The invention is an active prevention and control measure, and its biggest feature is not only that it can isolate pathogens, but more importantly, it can actively kill pathogens and keep the outside air clean, and its prevention and control effect is very obvious. If everyone wears a disinfection mask during the outbreak, it can not only protect healthy people, but also prevent and control the infected. Patients with symptoms such as cough) have a positive effect, preventing the potential harm of these carriers to healthy people. The present invention not only has the function of disinfection, but also has the function of helping the user to take a deep breath. The present invention completely relies on the user's spontaneous breathing, which can effectively promote the user's deep breathing and reduce the adsorption of viruses in the human body.

The design scheme proposed by the present invention can effectively block the release of pathogens from the patient to the external space, protect the external air, and also has a certain rescue effect on the patient, especially has a positive effect on mild or asymptomatic patients, and effectively protects the patient. Healthy people, block pathogens from being inhaled into healthy people through inhalation. If both mildly ill and suspected persons use the sterilization mask of the present invention in public places, healthy personnel may not even use the sterilization mask, or only need to use an ordinary medical mask. For example, when people enter a public place, allocating a disinfectant mask to each person can ensure that everyone is not infected. Since the polluted parts of the equipment designed in the present invention that need to be replaced are only the air inlet filter and disinfectant on the mask, and other parts such as the mask can be directly cleaned with disinfectant, the user can reuse the equipment, which can greatly Reduce the cost of use, with greater economic benefits.

The specific design of the present invention is suitable for the manufacture of general disinfection mask products. For those of ordinary skill in the art, the product structure, material selection and manufacturing method involved in the present invention can be realized in a general manufacturing enterprise, for example, in any manufacturing enterprise such as a medical equipment manufacturing factory, a plastic product factory, etc. be realized.

Those skilled in the art can easily understand that the above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention, etc., All should be included within the protection scope of the present invention.
