Description

Multichannel silica gel gauze mask

Technical Field

The invention belongs to the technical field of personal hygiene protective articles, and particularly relates to a multi-channel silica gel mask capable of preventing harmful gases such as germs, haze, particles, pollen, odor and the like from invading human body.

Background

In the daily activities of people, especially in the environment where the disease germs are easily spread by patients in the seasons of influenza, or in the seasons of haze, pollen, dust particles and the like, if the human body does not do respiratory protection, the human body is easily inhaled with the air which is bad for the human body, and the human body is damaged. In order to ensure the health of human body, the mask is required to be worn.

If the modern personal protective mask does not relate to the application in the aspects of industry and the like, the daily commonly used masks are roughly divided into two types, namely a multilayer melt-blown mask which is simple in structure and disposable. Its advantages are low cost, simple application and disposable. The disadvantage is the poor protection, which prevents only the inhalation or ejection of droplets on the surface. Secondly, the patient exhales germs all around the edge of the mask. The third disadvantage is that the breathing out of the nostril or the oral cavity can cause moisture, which is easy to cause the fogging of the glasses. The disadvantage is that the disposable is disposable, so that a large amount of the disposable is discarded after use, secondary pollution is easy to cause, and the environment-friendly concept is not met. In particular, in the flu season, two masks are consumed by one person every day and are used by all people, so that the demand is extremely high, and the situation of short supply and short demand often occurs.

The other type also belongs to a disposable mask. However, the mask is a sealed mask such as a so-called N95 mask with strong protection. Its advantage is that the outer ring of mask can be completely attached to face. Not only can prevent germs or particles from being directly inhaled, but also can prevent the hot and humid air containing germs from being directly exhaled out of the mask by a patient after the patient is not filtered. The sealed mask such as N95 can be completely attached to face to achieve bidirectional filtration. They are roughly classified into two categories. One is a completely closed mask, and the other is a mask with a one-way exhaust valve and a non-completely closed one-way valve.

The completely closed mask has outer ring in seamless contact with face. The air entering the respiratory tract can be inhaled by the human body or exhaled by the human body through multi-layer filtration after passing through non-woven fabrics, melt-blown fabrics or a plurality of multi-layer filter materials which can prevent the harmful gas from being filtered. In general, although a completely sealed mask is blocked by a plurality of layers of filter materials with a certain thickness, the inhaled air is smooth and smooth, and the normal inhaled air of a human body is not influenced. However, when a completely sealed mask is worn, because a large amount of hot and humid waste gas, including carbon dioxide and other gases, can not be completely and quickly exhausted when a human body needs to breathe, the hot and humid waste gas can stay in the mask and can not be completely and quickly exhausted, and a large amount of hot and humid gas stays in the mask for a long time. The breathing feeling of the human body is unpleasant, even dizziness and suffocation, which leads to bad results.

In order to solve the defects of the completely sealed mask, another type of incompletely sealed mask with a one-way valve exists, and the existing incompletely sealed masks such as N95 and the like are all provided with one-way valves. The structure is that under the condition that the structure is basically the same as that of a completely closed mask, only a hole is formed on the mask, and a one-way valve is arranged on the mask. The one-way valve is used for breathing out hot moisture from a human body, quickly opening the one-way valve, discharging the hot moisture, carbon dioxide and the like, and preventing the hot and wet waste gas from staying on the mask as far as possible. Since the circulated hot and humid bad gas is rapidly discharged, the feeling is good when the gas is sucked for the second time. Most of the groups who use fully-enclosed masks, both professional and non-professional, prefer to select such non-fully-enclosed masks with one-way valves. However, the non-completely sealed mask with the one-way valve is used under certain conditions, and another new disadvantage is that when the one-way valve of the non-completely sealed mask is opened, the gas exhaled by the human body is directly exhausted from the one-way valve without being filtered. When a patient with bacteria uses the mask, hot and humid exhaust gas exhaled by the patient with bacteria can be directly exhaled to the atmosphere with bacteria entrained, and the propagation and the diffusion of the bacteria are easily caused.

When wearing an airtight mask or a non-completely airtight mask, an elastic band is often tightened to enable the mask to be in seamless close contact with the face. The long-term use results in slight damage to facial skin, such as strangulation and allergy.

Although a small number of masks in the market adopt a structural form with a silica gel material as a base, the masks can be tightly attached to the face. However, the mask has many disadvantages as the mask made of other materials, and cannot achieve a structure of comfortable breath and a function of preventing germs from spreading. Moreover, most existing masks have single function and narrow application.

As disclosed in the patent with application number CN201720265139.8, a haze-proof antibacterial mask with a breathing one-way valve comprises: the mask body sequentially comprises a first medical non-woven fabric layer, an adhesive fiber layer, an anti-sticking isolation layer, a standing electrode melt-blown fabric layer, a nano-silver antibacterial adsorption layer and a second medical non-woven fabric layer from outside to inside; a tight edge sewed on the periphery of the mask body; the hangers are fixed at the left end edge and the right end edge of the mask body; and two breathing one-way valves symmetrically arranged on the mask body. Install two one-way breather valves at gauze mask body front end through the symmetry in time discharge the waste gas of human exhalation, the reinforcing is breathed the travelling comfort.

However, in the anti-haze and antibacterial mask with the breathing check valve disclosed above, the gas exhaled by the human body is directly discharged from the check valve without being filtered when the mask is used. When a patient with bacteria uses the mask, hot and humid exhaust gas exhaled by the patient with bacteria can be directly exhaled to the atmosphere with bacteria entrained, and the propagation and the diffusion of the bacteria are easily caused.

Such as raised, hollow, multi-layer, small blower configurations; the air inlet filter sheets with different thicknesses can be installed between the air inlet face cover and the first base, and the air inlet filter sheets with different functions, different thicknesses and different forms can be selected according to different environments. When the air inlet surface cover is in a relatively flat shape, the air inlet surface cover is enough to supply air required by normal breathing of a human body. When the human body has large amount of exercise, the amount of air required for breathing is also large. In this case, the air inlet cover can be changed into various shapes and forms such as convex, hollow and multilayer, thereby expanding larger space, sucking more air more quickly and providing enough air volume for users with large air volume.

Wherein, the filter house 3 of giving vent to anger is including the second base and the face lid of giving vent to anger, and on the second base was fixed in silica gel gauze mask main part 2, the bottom of the face lid of giving vent to anger was identical with the second base, and the face lid of giving vent to anger fits the straining on the second base, and forms the filtration check valve passageway of giving vent to anger that holds the cassette with second base intercommunication, and the cassette of the filter house 3 of giving vent to anger can be dismantled and connect between second base and the face lid of giving vent to anger, and the face lid of giving. In the invention, the detachable structure of the filter disc is the existing filter cotton replacing structure, and the filter disc can be repeatedly used for many times only by replacing different filter discs on the air outlet filtering one-way valve channel after cleaning and disinfection.

In practical application, the air outlet filter sheets with different thicknesses can be mounted between the air outlet face cover and the second base, and the air outlet filter sheets with different functions, different thicknesses and different forms can be selected according to different environments.

The air outlet cover is a one-way valve structure. When a human body exhales, the exhaled gas is exhausted outwards through the exhaust one-way valve after being filtered. The filter sheet used on the air outlet filtering one-way valve channel is different from the filter sheet of the air inlet, and is only used for filtering the exhaled air. The air-out resistance is relatively small. And when the air is sucked, the one-way valve is in a completely closed state. (the filter sheet on the air inlet filter channel is responsible for filtering the inlet air and filtering a small amount of exhaled air, so that the resistance is relatively large.) when the exhalation of a patient is not required to be blocked, the filter sheet on the air outlet channel can be cancelled, and only the air outlet surface cover with a one-way valve structure is used. Briefly, such a structure is invented to prevent cross-infection. When a healthy doctor contacts with a patient, the doctor can not install the filter sheet on the air outlet filtering one-way valve channel on the silica gel mask, and the patient needs to install the filter sheet on the air outlet filtering one-way valve channel in order to prevent the propagation of germs. And doctors also worry that the exhaled gas is bad gas, and the filter disc on the channel of the air outlet filtering one-way valve needs to be installed, so that cross infection is avoided.

Wherein, the air inlet filter part 6 is positioned at the position which is close to the nostril when the silica gel mask main body 2 is worn on the human face, and the air outlet filter part 3 is positioned below the air inlet filter part 6. In the invention, through the arrangement of the positions, the nose of a user can more conveniently suck air through the air inlet filtering part 6, and 2 air inlet filtering parts 6 and 2 air outlet filtering parts 3 are arranged on the silica gel mask main body 2 in a bilateral symmetry manner.

When the respiratory capacity is increased, the mouth needs to be opened to help more gas to enter and exit the human body. As the volume of breath increases, a large amount of moisture and hot gases are expelled from the mouth. In general, hot and humid air is diffused into the gaps around the mask. A clear example is when wearing a mask, and when the large mouth exhales, the glasses are covered with fog. The air blocking cross beam is arranged between the nostril and the mouth and can block most of hot moisture exhaled from the mouth from directly rushing upwards. After being blocked by the gas-blocking cross beam, hot moisture can be quickly discharged from the lower gas-out filtering one-way valve channel with lower resistance.

The specific implementation conditions of the invention are as follows:

the patient suspected of being infected with the infectious disease takes out the multichannel silica gel mask main body 2, opens the air inlet face cover and the air outlet face cover, and is provided with the air inlet filter sheet and the air outlet filter sheet. When the air filter is worn, the air inlet filter channel is arranged above the face, the air outlet filter one-way valve channel is arranged below the face, and the ear belts on two sides are hung on ears, so that the air filter can be normally used. Because the gas outlet surface is covered with the filter disc and the one-way valve structure, the exhaled toxic gas is filtered, and the chance of infecting others can be greatly reduced. When the patient needs to inhale oxygen, the oxygen tube can be inserted from the functional channel to supply the oxygen. When the activity of a patient is large, a hanging belt is additionally arranged to be connected with a hanging belt connecting hole 5 on the multi-channel silica gel mask, the hanging belt is hung on the head, and the mask is more stable. One more fixing guarantee is provided, so that the mask is not worried about falling off due to carelessness.

When the physician is concerned that his or her own exhaled air may also be contaminated, the mask may be worn in the manner described above for infectious disease patients.

Under normal conditions, when a surgeon performs a surgical operation, the surgeon needs to wear a mask. In this case, the filter sheet does not need to be arranged in the channel of the air outlet filtering one-way valve, and the exhalation is smoother. Meanwhile, because the silica gel mask has good sealing performance, hot and humid gas cannot be discharged from the upper side or the side of the silica gel mask, and the definition of the glasses is influenced. After most hot and humid gas is blocked by the gas barrier cross beam, the hot and humid gas can be quickly discharged from the lower gas outlet filtering one-way valve channel with lower resistance. If the water needs to be supplemented after long-term work, a straw can be inserted into the functional part 1 for drinking.

After the mask is used by the doctor, the mask is wrapped and sent to a high-temperature disinfection room. After high-temperature disinfection, the filter sheet is removed, and the mask can be reused. Only the inlet air and the outlet air need to be exchanged.

When the patient needs to go out to exercise in haze weather, the patient wears the air outlet filtering one-way valve without the filter disc in the channel, and a large amount of air, hot and humid air is directly discharged. When water is needed to be supplemented, the mask is not required to be taken off, and a straw can be inserted into the functional channel for drinking.

The work type and working environment of traffic policemen or workers, etc. have large workload and large air demand due to long working time. A small-sized external power air pump can be adopted and is connected with the standby channel 4 through a connecting pipe, and filtered safety gas is supplemented into the mask.

In the season of catching flu, the air outlet filter is selected to be installed or not according to the health condition. Two boxes can be carried in the working time of one day. One for the morning and one for the afternoon. The used multi-channel silica gel mask does not need to be exchanged on site. And directly putting the used multi-channel silica gel mask into a sealing box. The individual can be sterilized after work or in hospital. Soaking in boiling water at high temperature for sterilization. The silica gel material can resist high temperature up to more than 200 ℃, and the main body can not be damaged. The filter disc can be repeatedly used for a plurality of times as long as the filter disc is replaced.

The multi-channel silica gel mask implemented by the invention not only overcomes some important defects of the existing closed mask, but also can greatly widen the function and application range of the mask. The multi-channel silica gel mask is more reliable, safer, more comfortable and wider in application.

According to the multi-channel silica gel mask, the materials of the filter sheets for the air inlet filtering channel and the filter sheets for the air outlet filtering one-way valve channel are less, so that the multi-channel silica gel mask can be repeatedly used. The small wafer is convenient to produce, easy to store and small in occupied space. The silica gel mask is made of a silica gel material which is environment-friendly, safe, antibacterial and strong in ageing resistance, and the silica gel material is not afraid of ultraviolet rays and is not easy to age. The filter has the advantages of low cost, easy production, easy long-term storage, labor and material saving and small occupied area. The multi-channel silica gel mask is very suitable for long-term strategic storage.

The invention has the beneficial effects that: compared with the prior art, the respirator can inhale air through the air inlet filtering channel, the air outlet filtering one-way valve channel can only be used for exhaling due to the arrangement of the one-way valve structure in the air outlet filtering one-way valve channel, and when the respirator is used, the air is inhaled and filtered, and the exhaled air is also filtered and exhaled, so that the transmission of germs is prevented, and the probability that a virus infected person infects other people is greatly reduced; meanwhile, the mask has simple structure, low cost and convenient use, and can be used as an oxygen therapy cannula through the functional channel, also can use the functional channel as the channel of a liquid beverage straw, even can be provided with a microphone, an external filtering trachea channel and the like, and the functional channel can be completely sealed when not used according to various requirements; the multifunctional silica gel material expands and extends multiple functions, can be suitable for different application people, has wide application, does not have adverse reaction when contacting with skin due to the characteristics of the silica gel material, and has high comfort.
