Description

Face guard with air feed gasbag

Technical Field

Background

A plurality of masks are available in medical treatment, some masks are anti-virus and some masks are dustproof, but the existing masks are not tightly attached to the face of a human body, so that dust and viruses enter respiratory tracts to cause the masks to lose due functions. At present, the problem has been noticed, and some measures have been taken, such as the mask is provided with an iron clip at the nose bridge, and the iron clip is pinched when the mask is worn to fit the nose bridge, but the iron clip will loosen and fatigue, and the iron clip cannot completely prevent dust and virus from entering from the gap between the mask and the face. The iron clip obviously cannot enable the gap between the mask and the face to be in a micron scale matched with the filtering capacity of the mask. The N95 mask has poor air permeability and is uncomfortable to wear.

For diseases such as pneumonia, the gas for treating the diseases can be directly added into the lung, namely, the components for treating the diseases are added into the respiratory air. In alpine regions, the temperature of air breathed by people is extremely low, and the air has great damage to human bodies until diseases such as tracheal contraction are caused. In the north, there is a significant amount of PM2.5 in the air, which requires filter elements to remove.

Because the shapes of human faces are different, the nose bridge of eastern people is lower, and the nose bridge of western people is higher, so that the mask is difficult to completely fit with the faces of everyone. Therefore, it is necessary to design a multifunctional mask aiming at the problem of the fit between the face of the human body and the mask.

The oxygen supply air bag is used for oxygen inhalation of an oxygen inhalation patient, oxygen is supplied by the oxygen pipe, the oxygen pipe has certain air pressure, the oxygen can be stored in the air supply air bag, when the oxygen needs to be inhaled, the first one-way pressure valve is opened, the oxygen enters the mask, a human body inhales the oxygen, when the air is exhaled, the first one-way pressure valve is closed, the second one-way pressure valve is opened, and at the moment, the gas exhaled by the lock can only be exhausted from the air outlet of the mask. This can be used instead of or as an alternative to a ventilator.

Preferably, still include air pump, battery and air pump electric connection, the air pump is connected with air feed gasbag gas circuit, the air pump has the motor certainly. This kind of condition can be used for in the place that has many dust operations, if the air drill workman during operation, can send the very clean air in other places to the air feed gasbag with the air pump for the workman to use, when waiting to inhale, first one-way pressure valve opens, and the air admission face guard, human inhaled air, when waiting to exhale the air, first one-way pressure valve closes, and second one-way pressure valve opens, and the gas that locks the exhalation at this moment just can only go out from the face guard gas outlet. Because the station has much dust, the filtering is not feasible, the dust quickly blocks the filtering part, and the dust is not easy to suck air elsewhere. The air pump continuously sucks the required air from elsewhere and stores the air in the air supply air bag for the human body to inhale one time at a time. This maximizes worker protection from pneumoconiosis, a condition that is difficult to treat.

Preferably, an air tube 23 for preventing the wall of the air supply bag from blocking the outlet of the air supply bag is further included, the side wall of the air tube 23 is provided with a plurality of fine holes for the gas to pass through, and the air tube 23 is placed inside the air supply bag.

Preferably, the functional processing unit is a filtering component and/or an adsorption component and/or a heating component and/or an atomization component and/or a humidification component and/or an air negative ion component. The filter component is a component for replacing a mask and the like, and because the N95 mask is poor in air permeability, the air pump is used for enabling air to pass to replace human breathing, the process of breathing difficulty is changed into the process of driving the air pump to enable air to pass through by using electric energy, and people do not feel suffocated when the filter component is used. The adsorption component is used for adsorbing PM2.5 dust to protect the lung. The heating part is a heating part which leads the air to pass through high temperature, leads the temperature of the air to reach the temperature of the body temperature of human body, and avoids the disease caused by the stimulation of trachea due to too low temperature. The atomizing component is to add a certain component into the air to be breathed, atomize the liquid state of the component into gas state and inhale the gas together with the air to achieve a certain purpose, for example, a low-concentration phenol solution can be atomized into gas and inhaled together with the air, and the phenol solution directly enters a focus in a targeted way after reaching the lung to treat a certain disease. Because many lung pathogens are inhaled from the mouth and nose, it is possible to find where there is a virus and where there is a therapeutic drug. The humidifying unit may be water, which is the target of the atomizing unit. The air anion unit adds anions to the inhaled air.

The heating component and/or the atomization component and/or the humidification component and/or the air negative ion component are electrically connected with the battery.

Preferably, the air supply balloon is further provided with an overflow valve for preventing an excessive pressure. That is, the pressure in the air supply airbag exceeds a certain threshold, and the gas in the air supply airbag flows out from the overflow valve.

Preferably, the mask body 1 further comprises goggles covering eyes, a second bag body 3 is arranged at the edge of the mask body 1, a cavity is formed in the second bag body 3, and the mask body 1 is connected with the second bag body 3. The mask body 1 comprises a part for covering eyes and a part for covering mouth and nose. The face mask body 1 is a transparent plane body with equal thickness at the part right in front of eyes.

The function sensing unit comprises one or more of a carbon dioxide sensor, an oxygen sensor, a gas pressure sensor, a respiration frequency sensor and a specific gas concentration sensor. The function sensing unit is electrically connected with the battery, the monitoring instrument or the control panel.

The key to achieving this is also that the mask body seals well against the face, which is the case:

preferably, the first and/or second capsule 2, 3 is filled with a volume of gas and/or liquid at ambient temperature and pressure in its cavity that is less than the maximum volume that its cavity can be filled at ambient temperature and pressure and/or the first and/or second capsule 2, 3 is provided with an inflation hole so that the first and/or second capsule 2, 3 is filled by a user with a volume of gas and/or liquid at ambient temperature and pressure that is less than the maximum volume that its cavity can be filled at ambient temperature and pressure.

This is convenient for the person wearing the glasses to place the lens on the inner side, press the lens with the lens fixing piece 25, and then screw. This eliminates the need to wear a frame, which may interfere with the mask body 1.

Preferably, the visor is further provided with a visor extension 24, the visor extension 24 being in temple contact with the head.

Preferably, the first capsule 2 and/or the second capsule 3 are filled with gas and/or liquid in the cavity thereof, and the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 3 at normal temperature and normal pressure is smaller than the maximum volume of the cavity thereof at normal temperature and normal pressure. For example, the maximum volume that can be filled inside the first capsule 2 means the volume of the first capsule 2 that can be filled with the maximum amount of water when the first capsule 2 is sealed at a temperature of 20 degrees celsius at a pressure of gas and/or liquid equal to one atmosphere inside the first capsule 2. When in use, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 3 under normal temperature and pressure is smaller than the maximum volume of the cavity which can be filled under normal temperature and pressure. This is the case when said first and/or second capsule 2, 3 are non-elastic sealed capsules, if elastic, the volume of gas inside said first and/or second capsule 2, 3 is not certain, and the whole of said first and/or second capsule 2, 3 can be filled. That is, if the first and/or second capsules 2, 3 are elastic, the gas and/or liquid may not be filled, and the amount of inflation gas and/or liquid may be selected from one third to one half, or may be filled, or even may be over-inflated, so that the pressure in the first and/or second capsules 2, 3 is greater than a standard atmospheric pressure. Normal temperature and pressure mean a standard atmospheric pressure and a temperature of 20 ℃. For example, the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 3 may be gas, liquid, or liquid plus gas, and the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 3 refers to the sum of the volumes of gas and liquid, the volume of gas, the volume of liquid, and both the gas and the liquid. The fluid in the gas and/or fluid filled cavities of the first and/or second bladders 2, 3 comprises a flowable material in a high elastic state that is a high molecular material, which is also flowable or deformable in the direction of pressure to the other side.

Preferably, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 3 at normal temperature and pressure is less than one third to one half of the maximum volume of the cavity at normal temperature and pressure. When in use, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 3 under normal temperature and pressure is one third to one half of the maximum volume of the cavity which can be filled under normal temperature and pressure, and the gas can be filled before sale or when being used by a customer. For example, because the first and/or second bladders 2, 3 are not filled with gas, the first and/or second bladders 2, 3 can be inflated at the concave part of the human body under the action of small external force and deflated at the convex part of the human body, so that the mask body 1 can be fully attached to the human body, and the whole seal is realized. If the first and/or second elastic bladders 2, 3 are elastic, then the first and/or second bladders 2, 3 can be filled with gas and/or liquid, but the external force required to make the mask body 1 fit the human body is relatively large.

This brace 3 is intended to prevent the first 2 and/or second 3 bladder from having an arched channel that would allow the virus to enter the mouth when the first 2 and/or second 3 bladder is placed in facial engagement.

By arranging the first capsule body 2 and/or the second capsule body 3 on the mask body 1, when the mask body 1 is used, the gap between the mask body 1 and the face is filled with gas and/or liquid in the first capsule body 2 and/or the second capsule body 3 and certain pressure is kept, so that gas is prevented from entering and exiting from the gap between the face and the mask body 1. There should be no air permeable gap between the mask body 1 and the first and/or second bladders 2, 3, and the gas and/or liquid in the first and/or second bladders 2, 3 may be air or the like. The cost of using air is the lowest. The mask body 1 can be made of transparent materials, so that the face can be seen clearly, and people can not be mistaken. The mask body 1 can be made of hard materials or soft materials.

In addition, the mask body 1 has various shapes, can be attached to the face and can also leave a certain gap with the face, the first capsule body 2 and/or the second capsule body 3 can be purchased outside independently, and then the first capsule body 2 and/or the second capsule body 3 can be connected to the mask body 1. The first bag body 2 and/or the second bag body 3 are/is arranged at the edge of the mask body 1, the first bag body 2 and/or the second bag body 3 are/is inflated and sealed before use, and gas and/or liquid in the first bag body 2 and/or the second bag body 3 fills the gap between the mask body 1 and the face and keeps a certain pressure when the mask body 1 is used, so that gas is prevented from entering and exiting from the gap between the face of a human body and the mask body 1. Because the first bag body 2 and/or the second bag body 3 can completely fill the uneven part of the face of the human body, the part with low pressure of the first bag body 2 and/or the second bag body 3 can be automatically compensated, and the pressure of the first bag body 2 and/or the second bag body 3 on each side wall is equal, so that the mask can be worn comfortably. The first bag body 2 and/or the second bag body 3 can fill the space between the face of the human body and the mask, which is smaller than the maximum diameter formed by the space, and as long as the space is smaller than the specific maximum diameter, the first bag body 2 and/or the second bag body 3 block the space to prevent air from entering and exiting. The maximum diameter that the first capsule 2 and/or the second capsule 3 can assume is the diameter of a cylinder that the first capsule 2 and/or the second capsule 3 can assume by the pressure in its cavity being greater than the local atmospheric pressure. When the mask is not used, the gas in the first bag body 2 and/or the second bag body 3 is discharged, and the occupied volume of the mask in the storage or transportation process is small.

When the first bag body 2 and/or the second bag body 3 are provided with the inflation holes 4, the mask can be sold after the first bag body 2 and/or the second bag body 3 are inflated according to the inflation requirements of the first bag body 2 and/or the second bag body 3 without the inflation holes when being sold, and also can be sold without inflation, so that the mask can be inflated automatically when being used by a user, when the mask is used, the first bag body 2 and/or the second bag body 3 are folded and divided into two halves, one half of the bag body is compressed and cannot be inflated, the other half of the bag body is filled with gas, and the compressed half is released, so that the whole bag body is just filled with half of the gas.

The sealing can be realized by using the capsule body, and the capsule body is made of a plastic film and has low cost. The function of the capsule can also be replaced by soft materials such as silica gel and the like, but the cost is high, the cost is not cost-effective, and the best effect is achieved by the capsule.

In a particular embodiment, the material of the first capsule 2 and/or the second capsule 3 is provided as a poor conductor of heat, so as to be largely protected from external temperatures.

In a particular embodiment, the first and/or second bladders 2, 3 may be provided as a plurality of sealed bladders, the same effect being obtained, but more preferably, the plurality of sealed bladders is stacked from the face to the mask.

In a particular embodiment, the first and/or second body 2, 3 can be provided as a plurality of rows of sealed bodies, divided into an inner row and an outer row, with the same effect, but preferably, the plurality of rows of sealed bodies means a plurality of rows of sealed bodies, like mosquito coils, but with only one layer from the face to the mask.

In a particular embodiment, said first and/or second capsules 2, 3 can be provided as a plurality of rows of sealed capsules and as a plurality of layers of sealed capsules.

In a particular embodiment, said first capsule 2 and/or second capsule 3 can be provided as a soft material instead, for example in silicone.

In a specific embodiment, in the mask body 1 with goggles, the edge of the mask body 1 is provided with a third bag body 12 for enclosing the mouth, the nose and the eyes or the first bag body 2 for enclosing the mouth, the nose and the eyes, a second bag body 3 for enclosing the eyes or the third bag body 12 for enclosing the mouth, the nose and the eyes and a fourth bag body 13 for separating the mouth, the nose and the eyes. In short, the mask body 1 may enclose the mouth, nose and eyes with only one third bladder 12, as shown in fig. 8; alternatively, a third bladder body 12 may be used to enclose the nose, mouth and eyes, and a fourth bladder body 13 may be used to separate the nose, mouth and eyes, as shown in FIG. 6; it is also possible to enclose the nose and mouth with the first capsule 2 and the eyes with the second capsule 3, as shown in figure 7.
