the application relates to an oxygen supply mask which is provided with a cavity inner cover and a cavity outer cover, wherein the edges of the cavity inner cover and the cavity outer cover are connected, so that the cavity inner cover and the cavity outer cover are surrounded to form a hollow oxygen storage cavity. The mouth-nose separation partition is arranged in the middle of the cavity inner cover, so that the mouth-nose area of a user wrapped by the cavity inner cover is divided into two parts through the mouth-nose separation partition, wherein the upper part is a nose breathing area, and the lower part is a mouth breathing area.

Oxygen uptake is an effective measure for improving the symptoms of hypoxia against altitude reactions caused by rarefaction of air. In order to improve the living and working quality of the plateau area, portable oxygen inhalation devices have been used. The oxygen source of the portable oxygen inhalation device is divided into two technical forms of oxygen generation and oxygen storage, and the portable oxygen inhalation requirement outdoors on a plateau can be achieved through the matched oxygen delivery pipe and the corresponding oxygen supply mode. The nasal oxygen tube is matched with the oxygen inhalation device.
The nasal oxygen cannula is a common oxygen supply mode, is suitable for oxygen inhalation under various conditions of insufficient oxygen supply of human bodies, and is widely applied to plateau areas. After the nasal oxygen tube is connected with the oxygen inhalation device, the tail end of the catheter of the nasal oxygen tube is placed in the nostril to directly supply oxygen, thereby helping to improve the symptom of hypoxia. Although the tail end of the catheter of the nasal oxygen tube is placed in nostrils, the tail end of the catheter is still in a semi-open state, especially when a human body exhales, oxygen continuously output by the tail end of the catheter can be lost into the air along with the gas exhaled by the human body, so that the waste of the oxygen is caused, and the oxygen supply efficiency of the oxygen inhaler is greatly influenced. In order to reduce the loss of oxygen, the portable oxygen inhalation device is powered by a battery, and a pulse type oxygen supply mode is developed in a matching way. The pulse type oxygen supply is realized by arranging a sensor to detect the pressure change generated by human respiration and then opening the oxygen supply when the human inhales and interrupting the oxygen supply when the human exhales through an electric control valve, so that the oxygen supply airflow with short fluctuation is realized. The pulse type oxygen supply effect depends on the accuracy of a sensor, the response rate of an electric control valve and the intelligent degree of a control system, can be well adapted to regular breathing under a calm state of a human body, but has lag in regulation response when the breathing rhythm and the breathing tidal volume of the human body change. Especially when the human body enters a motion state, the breathing rhythm is changed from calm to jerky, and the breathing tidal volume is dynamically changed, so that the regulation burden of pulse type oxygen supply is greatly increased, and the regulation disorder of pulse type oxygen supply is easily caused. In addition, electronic modules such as batteries, sensors, control systems, and the like are sensitive to ambient temperature and are susceptible to performance degradation or failure in a cold highland environment. For the portable oxygen storage device, a pressure reducing valve is generally adopted to adjust the oxygen flow, and the pulse oxygen supply mode is difficult to be applied to the portable oxygen storage device due to lack of battery power supply.
For the above reasons, there is a need for an oxygen delivery mask that can effectively deliver oxygen in the event of changes in respiratory rhythms and respiratory tidal volumes.
Referring to fig. 1 to 8, the present application provides an oxygen supply mask, which comprises a cavity inner cover 3-1, a cavity outer cover 3-2, an oronasal separation partition 9, an oxygen inlet pipe 1 and a pressure balance pipe 2.
Wherein, the cavity inner cover 3-1 and the cavity outer cover 3-2 are connected with the edges of the cavity inner cover 3-1 and the cavity outer cover 3-2, so that the cavity inner cover 3-1 and the cavity outer cover 3-2 are surrounded to form a hollow oxygen storage cavity 10.
The cavity inner cover 3-1 is contacted with the mouth and nose of the user, the cavity outer cover 3-2 is far away from the mouth and nose of the user, and the cavity inner cover 3-1 can be made of silica gel materials so as to improve the wearing comfort of the user. The housing 3-2 can be made of plastic materials, so that the overall strength of the oxygen supply mask is improved.
The edges of the inner housing 3-1 and the outer housing 3-2 may be bonded together such that the inner housing 3-1 and the outer housing 3-2 enclose an oxygen storage chamber 10.
After the edges of the cavity inner cover 3-1 and the cavity outer cover 3-2 are connected, channels for breathing (the channels for breathing comprise an oxygen-enriched mixed suction channel 11 and a grating mouth cover 12) are reserved in the middle area of the cavity inner cover 3-1 and the cavity outer cover 3-2, that is, the edges of the breathing channels formed by the cavity inner cover 3-1 and the central area of the cavity outer cover 3-2 are bonded, so that an annular oxygen storage cavity 10 which surrounds the periphery in the cavity outer cover 3-2 is formed.
The oxygen storage chamber 10 serves to pre-store oxygen injected therein. That is, in the case that the oxygen inlet pipe 1 is connected to the wall of the bottom region of the chamber housing 3-2, oxygen can be injected into the oxygen storage chamber 10 through the oxygen inlet pipe 1 so that the oxygen can be pre-stored in the oxygen storage chamber 10 for standby.
The mouth-nose separation partition 9 is arranged in the middle of the cavity inner cover 3-1 and separates the cavity inner cover 3-1 to form a nose breathing zone and a mouth breathing zone. The split partition is a flat structure, and the edge of the split partition is connected with the wall of the cavity inner cover 3-1, so that the split structure is formed.
Wherein the wall of the inner cover 3-1 of the cavity of the nose breathing zone is provided with an inhalation valve 5 for inhaling oxygen so that the inhalation valve 5 is in an opened state. The nose breathing zone is communicated with the oxygen storage cavity 10, and the mouth-nose separation partition 9 is provided with an exhalation valve 6, so that the nose breathing zone is communicated with the mouth breathing zone in an opening state of the exhalation valve 6.
It should be noted that, when the space in the oxygen storage chamber 10 is limited and the oxygen pre-stored in the oxygen storage chamber 10 is greater than the upper limit of storage, the excess oxygen needs to be discharged, and thus, the air pressure balance tube 2 is disposed on the chamber housing 3-2, so that the excess oxygen in the oxygen storage chamber 10 is discharged by using the air pressure balance tube 2, and the air pressure in the oxygen storage chamber 10 is the same as the air pressure of the outside. Specifically, the air pressure balance tube 2 includes opposite ends, wherein one end portion of the air pressure balance tube 2 is disposed in the chamber housing 3-2 so as to communicate with the inside of the oxygen storage chamber 10, and the other end of the air pressure balance tube 2 is used for discharging oxygen.
To avoid the waste of the discharged oxygen, one end of the air pressure balance tube 2 from which the oxygen is discharged is bent at an angle so that the oxygen discharged from the bent air pressure balance tube 2 is directed toward the breathing passage so that the nose sucks the oxygen discharged from the air pressure balance tube 2.
The oxygen-enriched mixed suction channel 11 is arranged on the cavity inner cover 3-1 and the cavity outer cover 3-2 of the nose breathing zone so that the nose breathing zone is communicated with the outside through the oxygen-enriched mixed suction channel 11; wherein, the channel opening of the oxygen-enriched mixed absorbing channel 11 is covered with oxygen storage cotton.
Specifically, the bent end of the air pressure balance tube 2 is connected to the oxygen storage cotton, for example, the bent end is inserted into the oxygen storage cotton, so that the oxygen discharged from the air pressure balance tube 2 may enter the oxygen storage cotton. When a user inhales through the nose, external air enters the nose breathing zone through the oxygen storage cotton and is inhaled by the nose, and when the external air passes through the oxygen storage cotton, oxygen on the oxygen storage cotton is substituted into the nose breathing zone together. The above structure can effectively utilize the oxygen discharged from the air pressure balance pipe 2.
It should be noted that, the oxygen storage cotton may be placed at the front end of the mask cavity body 3 and placed in an accommodating space capable of accommodating the oxygen storage cotton, and the accommodating space may be an accommodating space formed by surrounding a frame structure, so that one end of the air pressure balance tube 2 bent extends into the frame, that is, one end of the air pressure balance tube 2 bent is placed in the accommodating space, and thus, air discharged from one end of the air pressure balance tube 2 bent enters the accommodating space and contacts with the oxygen storage cotton in the accommodating space, so that the oxygen storage cotton is rich in oxygen. The frame is fixed on the mask cavity body 3 and covers the oxygen inlet of the oxygen-enriched mixed suction channel 11. When the nose inhales, air firstly passes through the oxygen storage cotton, so that the air carries oxygen on the oxygen storage cotton to enter the oxygen-enriched mixed inhalation channel 11, and finally enters the nose breathing zone.
Further, the oxygen supply mask further comprises an air suction valve seat 7, the air suction valve seat 7 is arranged in the oxygen-enriched mixed suction channel 11, and the edge of the air suction valve seat 7 is abutted against the edge of the oxygen-enriched mixed suction channel 11. That is, the air intake valve seat 7 is inserted into the oxygen-enriched air mixing and sucking passage 11 to overlap with the oxygen-enriched air mixing and sucking passage 11. One end of the air suction valve seat 7 penetrating through the oxygen-enriched mixed suction channel 11 is abutted on the oxygen storage cotton, and the edge of the other end is abutted on the edge of the oxygen-enriched mixed suction channel 11 and forms a connection relationship with the oxygen-enriched mixed suction channel 11, so that the air suction valve seat 7 is fixed on the oxygen-enriched mixed suction channel 11.
Wherein, the air suction valve seat 7 is provided with an air suction valve plate 8 at the side facing away from the oxygen-enriched mixed suction channel 11. And when the air suction valve plate 8 is in an open state, the nose breathing zone is communicated with the outside through the air suction valve seat 7 and the oxygen-enriched mixed suction channel 11.
The opening negative pressure value of the air suction valve plate 8 is smaller than the opening negative pressure value of the suction valve 5. Therefore, the air suction valve plate 8 can be opened in preference to the air suction valve plate 5, that is, when a user breathes calmly, the nose of the user can breathe through the opening and closing of the air suction valve plate 8, and when the user breathes violently, the air suction valve plate 5 and the air suction valve plate 8 work simultaneously, so that the oxygen supply amount is increased.
Specifically, the air suction valve 8 may be made of a flexible material, and the suction valve 5 may appropriately increase the friction force between the air suction valve 8 and the wall of the cavity inner cover 3-1 during the reciprocating motion, so that the opening negative pressure value of the air suction valve 8 is smaller than the opening negative pressure value of the suction valve 5. This is only an exemplary illustration, and other ways may be used to achieve a negative pressure value for opening the air intake valve 8 that is less than the negative pressure value for opening the intake valve 5, which is not limited by the present application.
A grill type mouth cover 12 is placed on the inner and outer chamber covers 3-1 and 3-2 of the mouth breathing zone so that the mouth breathing zone communicates with the outside through the grill type mouth cover 12. The grill type mouth cover 12 can facilitate breathing of the mouth, and the grill type structure can ensure that sound is transmitted to the outside when the mouth speaks.
In some embodiments, the oxygen supplying mask further comprises a sealing edge 13, wherein the sealing edge 13 is arranged at the edge of the inner wall of the cavity inner cover 3-1 and extends towards the center of the cavity inner cover 3-1.
Wherein, the sealing edge 13 is made of flexible material, which increases the fitting effect of the inner cavity cover 3-1 and the face of the user when the user wears the oxygen supplying mask, that is, increases the tightness between the inner cavity cover 3-1 and the face of the user.
The sealing edge 13 is formed integrally with the housing 3-1. The sealing edge 13 is a flexible sheet-like structure, the shape of which can be set according to the shape of the nose and mouth. The sealing edge 13 is circumferentially arranged along the edge of the inner cavity cover 3-1, and the area surrounded by the middle part of the sealing edge 13 is used for the mouth and nose of a user to pass through, so that the mouth and nose can pass through the area surrounded by the middle part of the sealing edge 13 and be placed in the wrapping area of the inner cavity cover 3-1.
In some embodiments, the number of the exhalation valves 6 is two, the interval between two exhalation valves 6 is arranged on the oronasal separation partition 9, and when the nostrils exhale, the gas exhaled by each nostril is sprayed on the area on the oronasal separation partition 9, and one exhalation valve 6 is correspondingly arranged.
Wherein, the exhalation valve 6 is correspondingly arranged at the nostril when exhaling, and the exhaled gas (waste gas) is sprayed at the region corresponding to the mouth-nose separation partition 9, so that the sprayed waste gas can be flushed out of the exhalation valve 6 when exhaling at the nostril, thereby enabling the waste gas to pass through the exhalation valve 6 and enter the mouth breathing zone. Conversely, when the nostrils inhale, the exhalation valve 6 receives suction first, so that the exhalation valve 6 is closed in time, and air inhaled by the nostrils is guaranteed to be oxygen entering the nose breathing zone through the inhalation valve 5 and the air inhalation valve plate 8.
In some embodiments, the oxygen mask further comprises a drain valve 4, the drain valve 4 is disposed at the bottom of the cavity cover 3-2, and the drain valve 4 penetrates through the oxygen storage cavity 10, so that one end of the drain valve 4 is disposed on the wall of the cavity inner cover 3-1, and thus, condensed water formed in the cavity inner cover 3-1 flows from the drain valve 4 to the outside. Thereby avoiding the retention of condensed water in the cavity inner cover 3-1.
The working principle is as follows:
the application relates to an oxygen supply mask cavity for altitude sports, which is characterized in that when the nose of a human body inhales, an air suction valve plate 8 and an air suction valve 5 are opened, two exhalation valves 6 are closed, and the opening negative pressure value of the air suction valve plate 8 is slightly smaller than that of the oxygen suction valve 5. When a user inhales slowly, oxygen is mainly supplied by the oxygen-enriched mixed suction channel 11, and when the user inhales deeply in a motion state, oxygen is simultaneously supplied by a double diversion channel formed by the oxygen-enriched mixed suction channel 11 and pure oxygen directly (after an inhalation valve 5 is opened, oxygen in an oxygen storage cavity 10 enters a nose breathing zone wrapped by a cavity inner cover 3-1 through the inhalation valve 5); when nose expiration is adopted, the air suction valve plate 8 and the suction valve 5 are closed, two exhalation valves 6 arranged on the mouth-nose separation partition 9 are opened, exhaled air enters the mouth breathing zone through the exhalation valves 6 and is discharged through a grid type mouth cover 12 of the mouth breathing zone, at the moment, oxygen continuously supplied by a portable oxygen storage/generation device (oxygen inhalation device) flows into the oxygen storage cavity 10 through the oxygen inlet pipe 1 for temporary storage, when the oxygen storage cavity 10 is filled with oxygen, the oxygen can overflow from the air pressure balance pipe 2, and the periphery of the outer side of the air suction valve seat 7 is enriched (the overflowed oxygen is retained in oxygen storage cotton), and then the oxygen-enriched mixed suction channel 11 is used for inhaling the nose breathing zone for oxygen supply; when the mouth is adopted for exhalation, the air inhalation valve plate 8, the inhalation valve 5 and the exhalation valve 6 are all in a closed state, exhaled air is directly exhausted from the grille mouth cover 12 of the mouth separation cavity, and oxygen continuously supplied by the portable oxygen storage/generation device can be temporarily stored in the mask during the period, so that loss and waste are avoided.
When in inhalation, because the oxygen supply mask is tightly adhered to the face, negative pressure is generated in the nose respiratory region, at the moment, the air inhalation valve plate 8 is opened first, external air is mixed with oxygen enriched at the periphery of the outer side of the air inhalation valve seat 7, and the oxygen is inhaled into the nose respiratory region through the oxygen-enriched mixed inhalation channel 11; under the motion state, due to the increase of the breathing intensity, the negative pressure generated in the nose breathing area is increased, the air suction valve plate 8 and the oxygen suction valve 5 are driven to be opened in sequence, and the temporarily stored pure oxygen in the hollow oxygen storage cavity 10 is sucked through the pure oxygen direct suction channel, so that the hypoxia symptom is enhanced and improved.
During exhalation, the highland sports oxygen supply mask can adapt to mouth exhalation, nose exhalation and multiple exhalation modes of mouth and nose simultaneous exhalation; the design of the double exhalation valve 6 ensures the rapid discharge of gas during nasal exhalation; the normally closed design of the double exhalation valve 6 effectively controls the loss and waste of oxygen in the oxygen supply mask in the exhalation process.
In one embodiment, the oxygen supply mask provided by the application comprises an oxygen inlet pipe 1, an air pressure balance pipe 2, a mask cavity body 3, a drain valve 4, an air suction valve 5, two exhalation valves 6, an air suction valve seat 7 and an air suction valve plate 8.
The mask cavity body 3 is formed by bonding a cavity inner cover 3-1 and a cavity outer cover 3-2. After the bonding, a hollow cavity is formed between the cavity inner cover 3-1 and the cavity outer cover 3-2 for storing oxygen. An oxygen inlet pipe 1 is arranged at an oxygen inlet below the mask cavity body 3, and the other end of the oxygen inlet pipe 1 is connected with a portable oxygen generating/storing device; the air pressure balance pipe 2 is arranged at the interface of the air pressure balance pipe 2 below the mask cavity body 3, oxygen overflows from the other end of the air pressure balance pipe 2 to the periphery of the outer side of the air suction valve seat 7, and at the moment, the oxygen overflowed from the other end of the air pressure balance pipe 2 is still effectively controlled in the oxygen supply mask; the mask cavity body 3 is provided with an oxygen inhalation valve 5, and is opened during inhalation and closed during exhalation; two exhalation valves 6 are arranged on the mouth-nose separation partition 9 of the mask cavity body 3, and are opened when the nose exhales and closed when the nose exhales.
When the highland sports oxygen supply mask is used, the highland sports oxygen supply mask can be effectively adapted to oxygen supply of a plateau in a calm state and a sports state, further satisfies oxygen supply of various mouth-nose coordination breathing modes in the sports state, and obviously improves feeling of suffocating when wearing the oxygen supply mask in the highland sports state; meanwhile, the oxygen-saving effect of the traditional pulse oxygen supply is achieved, and the device has more advantages in adaptability to the cold environment of the highland and compatibility of the portable oxygen-making and oxygen-storing devices.
The application also provides an oxygen inhalation device which comprises an oxygen making or storing device and the oxygen supply mask, wherein the oxygen making or storing device is connected with the oxygen supply mask through an oxygen inlet pipe 1.

In summary, the oxygen supply mask provided by the application is matched with the oxygen inhalation device, and is an oxygen supply mode for supplying oxygen to a user, and the oxygen supply mask accumulates oxygen around the mouth and nose, so that the mouth and nose can obtain higher-concentration oxygen supply, and the oxygen supply efficiency is improved. When the oxygen supply mask adopts a closed structure, the breathing generates pressure to drive the exhalation valve 6, so that the automatic regulation and control of intermittent oxygen supply can be realized, and the intermittent oxygen supply is adapted to the breathing rhythm of a human body. The physical structure regulated by the exhalation valve 6 has better responsiveness, stability and reliability of the exhalation valve 6, has strong adaptability to the cold environment of the plateau and is matched with the portable oxygen inhalation device.

Can improve the oxygen utilization efficiency and relatively prolong the oxygen supply time.
The application has the advantages that:
the oxygen supply mask can realize automatic regulation control of intermittent oxygen supply (the breathing control of the inhalation valve 5 and the exhalation valve 6 by a user) without depending on battery power supply, and can widely support matched oxygen supply with a portable oxygen generation and storage device. The hollow oxygen storage cavity 10 has the function of transferring and storing oxygen, and converts continuous oxygen supply input into the mask by the portable oxygen generation and storage device into intermittent oxygen supply; the mouth-nose separation partition 9 has the function of adapting to various mouth-nose coordination modes in motion breathing, the oxygen-enriched mixed inhalation channel 11 of the nose breathing zone has oxygen inlet efficiency, and the oxygen inlet efficiency is improved, and the grille type mouth cover 12 of the mouth breathing zone is designed, so that the exhalation resistance can be reduced and the speaking sound conduction can be improved; the oxygen-enriched mixed-sucking channel 11 mixes the external air with the oxygen overflowed from the air pressure balance pipe 2, oxygen is supplied through the air suction valve 5 after oxygen enrichment is formed, and the pure oxygen direct-sucking channel supplies the pure oxygen in the hollow oxygen storage cavity 10 through the suction valve 5, so that the oxygen-sucking efficiency is maintained when the motion breathing tidal volume is increased; the normally closed type exhalation valve 6 group has an intermittent oxygen supply self-adaptive control function, and the exhalation valve 6 is driven by pressure generated by human breathing, so that the intermittent oxygen supply can automatically adapt to the breathing rhythm of the human body.
The application has the beneficial effects that:
(1) The oxygen storage cavity 10 is hollow by utilizing the structural characteristics of the oxygen supply mask, so that the oxygen storage quantity and the oxygen storage tightness of the oxygen supply mask are improved; the oxygen mask can adapt to the deep breathing state with a slower frequency under the altitude movement state, so that oxygen can be stored in the oxygen mask to the greatest extent, the leakage and the loss are avoided, and the oxygen utilization rate is improved;
(2) The double diversion channels can adapt to calm state oxygen supply and movement rapid breathing oxygen supply, and balance of the inhalation amount and the oxygen supply quality of the oxygen supply mask is realized. Not only ensures the high-purity oxygen absorption in the hollow oxygen storage cavity 10, but also can suck and fully utilize the oxygen overflowed from the oxygen storage cavity 10 through the oxygen-enriched mixed absorption channel 11.
(3) The mouth-nose separation has the function of adapting to various mouth-nose coordination modes in motion breathing, meets the mouth-nose coordination breathing oxygen supply requirement under the higher intensity motion state, adapts to the rapid state of the mouth-nose coordination breathing, enables the breathing to be smooth when wearing the oxygen supply mask in the plateau motion, improves the oxygen inhalation efficiency by closely enriching oxygen in the nose separation cavity, adopts the grating mouth cover 12 in the mouth separation cavity, can reduce the exhalation resistance in the semi-open design, effectively transmits speaking sound from the inside of the mask when wearing the mask, and facilitates speaking communication when wearing the oxygen supply mask.
(4) The normally closed type exhalation valve 2 group (two exhalation valves 6) has an intermittent oxygen supply self-adaptive control function, and the exhalation valves 6 are driven by pressure generated by human breathing, so that oxygen can be stored and released to automatically adapt to the breathing rhythm of the human body. Under the condition of no need of battery power supply, the intermittent oxygen supply control is realized only through a physical structure, the responsiveness, the stability and the reliability are good, the adaptability to the plateau cold environment is strong, and the device is compatible with the portable oxygen generation and oxygen storage device.
The following is an exemplary illustration of motion breathing:
in the exercise state, the oxygen consumption of the human body is rapidly increased, and even the oxygen consumption is increased by 20 times compared with that in the calm state in the case of intense exercise or heavy labor, so that the user can make up for the oxygen by increasing the depth and frequency of breathing and increasing the ventilation. In the plateau anoxic environment, oxygen compensation in a motion state is more difficult, and the oxygen supply mask needs to adapt to a breathing mode to promote the absorption and utilization of oxygen.
The respiratory modes of the altitude motion include, but are not limited to:
(1) The nasal inhalation is performed by nasal inhalation, so that inhaled gas can be heated, moistened and filtered by nasal hair, the irritation of the inhaled gas is reduced, the opportunity of causing bronchospasm is avoided, and the respiratory resistance is improved by oral exhalation.
(2) Deep slow breathing is achieved, namely, the breathing is performed slowly and uniformly until the breathing is difficult to re-inhale, then the breathing is performed uniformly, and the internal gas is exhausted as much as possible, so that the respiratory tidal volume is increased, invalid breathing is reduced, and the breathing efficiency is improved.
(3) The shrinkage breathing, namely mouth-lip shrinkage, is like blowing a candle, and exhales slowly to improve the respiratory airway pressure, prevent the airway from being early closed to cause a great deal of retention of air in the lung, improve ventilation and air exchange functions, eliminate impurities accumulated in the lung and increase the lung capacity.
When oxygen supply is carried out in the altitude sports, the oxygen supply mask can adapt to the breathing mode in the altitude sports state, so that the utilization rate of oxygen supplied by the portable oxygen storage/generation device is improved.
