Description

A protective breathing training device

Technical field

The invention relates to a protective respiratory training device, which belongs to the technical field of medical equipment.

Background technique

Breathing training is a commonly used medical method to exercise breathing ability. It can be used to enhance the strength of inspiratory and expiratory muscles, improve human heart and lung function, increase lung capacity, and improve general health. For those who suffer from lung diseases or have undergone lung surgery, Patients need to use breathing trainers to rehabilitate their breathing ability to promote the return of lung function to normal as soon as possible; usually breathing training is divided into two parts: exhalation training and inhalation training, which can increase the strength of expiratory muscles and inspiratory muscles respectively. strength.

Since particulate matter of different concentrations and sizes is unavoidable in the human living environment, inhalation of large amounts will cause varying degrees of damage to the mucociliary clearance system and alveoli of the trachea at all levels. Especially for patients with existing respiratory diseases, breathing training The tidal volume during breathing is several times higher than during calm breathing, and inhalation of large amounts of particles in the air can cause lung infection; Patent 201410231150.3 discloses a breathing training device, including an inhalation training component, an exhalation training component, a gas drainage component and a breathing terminal , the respiratory terminal includes a shell and a filter assembly, which enables inhalation training and exhalation training to be performed simultaneously in a clean breathing environment, but the inhaled and/or exhaled gas needs to pass through a slender drainage assembly, which increases the inhalation and/or The resistance of exhaled air, and the device has too many parts, is inconvenient to operate, and is inconvenient for users to wear for daily activities; patent US20180280758A1 discloses an infinitely adjustable training mask with an air filter and a water fountain, including adjustable inhalation resistance assembly, exhaust channel assembly and particulate air filter. The particulate air filter is installed inside the adjustable inhalation resistance component to provide the wearer with respiratory protection when inhaling, reduce the risk of inhaling particulate matter in the air during outdoor training, and at the same time Replenish water at any time. However, the particulate air filter has a small filtration area and a single-layer filter membrane. The purification effect is not good, and a large air resistance is generated when the gas flows through the filter membrane, which additionally increases the gas resistance during breathing training and interferes with breathing. Training the adjustment of air resistance reduces the effect of breathing training.

Contents of the invention

The invention provides a protective breathing training device, which can not only select appropriate breathing training modes and breathing training air resistance according to individual needs, but also perform breathing training under two-way protection of inhalation and exhalation, and the gas filter assembly designed with a three-dimensional structure is The area of the gas filter component is doubled in a limited space to ensure the purification effect while minimizing the exhalation or inhalation resistance of the gas filter component itself. The device should be worn and worn.

The invention is implemented as follows: a protective breathing training device, including a gas filter component and a breathing training component. The gas filter component is connected by a gas filter component and an auxiliary component. The space enclosed by the two is the gas filter component. In the inner cavity, the gas filtered by the gas filter component first enters the inner cavity of the gas filter component, and then flows out through the opening of the gas filter component; the breathing training component includes a hollow passage component and a matching resistance adjustment component, which are formed when the two are used together The gas passage is a breathing training passage. The breathing training passage is provided with a distal opening and a proximal opening. The distal opening of the breathing training passage of the breathing training component is fluidly connected to the inner cavity of the gas filter component. The proximal opening of the breathing training passage is connected to the respiratory tract opening.

The auxiliary components play one or all functions such as supporting, shaping, forming passages, adjusting flow direction, etc.

The resistance adjustment component can be a component that can adjust the breathing resistance, or it can be a component with a fixed resistance value; if it is a component with a fixed resistance value, it can be set into multiple single components with different fixed resistance values, from low to high during breathing training. Use progressively.

The proximal opening of the breathing training passage is connected to the respiratory tract opening, and may be directly connected, such as placing the proximal opening of the breathing training passage in the mouth or covering the mouth and nose opening; when the design is such that the proximal opening of the breathing training passage is embedded with a gas filter assembly, it is connected to the respiratory tract opening through the opening of the gas filter component; after the resistance adjustment component and the passage component are used together, the gas path formed between the two is the respiratory training path, and the expansion surface area of the gas filter component is larger than the distal opening of the respiratory training path. The cross-sectional area can reduce the impact of the gas filter component's own resistance on the resistance adjustment range of breathing training.

The proximal opening of the respiratory training channel is connected to the respiratory tract opening through the opening of the gas filter component. This means that the opening of the gas filter component extends out of the channel and is directly connected to the respiratory tract opening, and the proximal opening of the respiratory training channel is located in this channel.

The gas filter component and the auxiliary component are enclosed to form the inner cavity of the gas filter component. It can be a single blade-shaped gas filter component and the auxiliary component. It can also be a blade-shaped front leaf and a rear leaf that are sealed and connected to form a gas filter. The filter component is then enclosed with auxiliary components.

Further, in order to reduce the volume, at least the distal opening of the breathing training channel is inserted into the inner cavity of the gas filter assembly or the inner cavity passage of the gas filter assembly.

In order to facilitate the adjustment of air resistance during breathing training, the resistance adjustment component of the breathing training assembly can be relatively displaced with the passage component when rotating, thereby adjusting the air resistance during exhalation training and/or inhalation training.

Specifically, during the rotation operation, the air inlet and outlet cross-sectional area of the airflow adjustment port in the breathing training passage can be adjusted, thereby adjusting the breathing resistance.

The relative displacement can be a relative displacement of circular rotation, or a relative displacement of left and right, front and back; it can be a direct relative displacement between the resistance adjustment component and the passage component, or it can be an indirect relative displacement with the help of additional auxiliary components. .

In order to indicate the air resistance level for exhalation and/or inhalation training, marks such as scale lines can be set on the resistance adjustment component to facilitate the user to select the air resistance for breathing training according to needs.

In order to be able to train the inhalation function or the exhalation function independently, a gas barrier component that allows gas to flow in one direction is also included. The gas barrier component is provided with a gas flow port, and the gas flow port is connected to the inner cavity of the gas filter component; used for training inhalation When functioning, the gas blocking component corresponding to inhalation is closed during inhalation and opened during exhalation. When used for training the exhalation function, the gas blocking component corresponding to exhalation is closed during exhalation and open during inhalation.

The gas barrier component can select a one-way air valve and be used in conjunction with the resistance adjustment component at the same time; when the one-way air inlet valve that allows gas to flow from the external environment into the respiratory tract opening is selected, the gas flows from the breathing training component during exhalation. When the training passage passes, the exhalation function can be trained. When the one-way outlet valve is selected to allow gas to flow from the opening of the respiratory tract to the external environment, and the gas flows through the breathing training passage during inhalation, the inhalation function can be trained.

One solution is that the device includes at least one gas filter component, and the auxiliary component of the gas filter component extends out of two channel tubes, which can connect two respiratory training components or a respiratory training component and a gas barrier component at the same time.

The two channel tubes can extend out two inner cavity passages of the gas filter assembly. The two inner cavity passages of the gas filter assembly can be connected with the breathing training passage of the breathing training assembly at the same time; they can also be connected with the gas of the breathing training passage and the gas barrier assembly. The flow ports are connected separately.

The two inner cavity passages of the gas filter assembly may be two passages provided on the same gas filter assembly, or they may be passages provided on two independent gas filter assemblies.

When the channel tube of the gas filter component is only connected to the breathing training component, inhalation and expiration resistance training can be performed at the same time; when the channel tube is connected to both the breathing training component and the gas barrier component, separate exhalation training or inhalation training can be performed ; When two channel tubes are connected to two breathing training components at the same time, the left and right gas adjustment ports can be adjusted to different cross-sectional areas, that is, the air resistance on the left and right sides is different, which can produce different airflow distribution on both sides, such as providing to the nasal septum. Biased users.

The respiratory training device also includes a ventilation terminal component, the distal opening of the ventilation terminal component is connected to the proximal opening of the respiratory training channel, the proximal opening of the ventilation terminal component is connected to the respiratory tract opening, and the peripheral portion of the proximal opening of the ventilation terminal component is connected to the mouth and/or nose Conformal fit to surrounding skin.

The ventilation terminal component may be an independent component, or may be a component integrated with the gas filter assembly or the respiratory training component, that is, the ventilation terminal component is arranged on the gas filter assembly or the respiratory training component.

The proximal opening peripheral portion of the ventilation terminal component conforms to the facial skin. It may conform to the nose skin, that is, only perform nasal breathing training, or it may conform to the oral skin, that is, only perform oral breathing training. Oral and/or nasal breathing training can be performed at the same time by conforming to the skin of the mouth and nose at the same time.

The proximal opening periphery of the ventilation terminal component conforms to the facial skin, and the part in contact with the skin is composed of a nasal area, an oral area and an oronasal transition area that are integrated into one body. When in use, the proximal opening periphery of the ventilation terminal component The part is attached to the face to form an external breathing cavity isolated from the external environment.

When the mouth is opened, the movement of the temporomandibular joint causes a gap between the ventilation terminal component and the facial skin. In order to eliminate the risk of inhaling pathogenic particles in the air from the gap, it also includes at least one elastic unit that can contact the peripheral part of the mouth area of the ventilation terminal component. The elastic force The unit may undergo corresponding deformation and/or displacement due to the movement of the facial skin.

The external respiratory cavity refers to the space between the mouth and nose airway openings and the proximal opening of the breathing training passage.

The target area of the elastic unit is located at the mouth area of the ventilation terminal component where the skin around the lower lip is in contact or at the mouth area of the ventilation terminal component where the skin on both sides of the cheek is in contact; the elastic unit can act directly or indirectly on the above target area.

Considering the mechanical balance of simultaneous displacement of the ventilation terminal component in contact with the facial skin when the user opens the mouth, it is preferable to design two sets of left and right elastic units to respectively act on the area around the proximal opening of the ventilation terminal component that contacts the user's left and right cheeks.

In order to achieve more health benefits while breathing training, it also includes a negative ion component that can generate negative ions in the air. At least the negative ion generating end of the negative ion component, such as a carbon brush, a metal tip, etc., is installed in the external respiratory cavity and/or the respiratory training pathway. It releases negative ions at close range and is surrounded by filtered pure air. The output of negative ions and the utilization rate of the human body are the highest. What this device generates is usually negative oxygen ions.

In order to ensure a more stable, continuous and high-concentration supply of negative ions, electronic supply components are also included. Electronic supply components are composed of materials rich in free electrons and/or easy for free electrons to flow on them, such as various metals, conductive rubber, Conductive ceramics, piezoelectric materials, etc., electronic supply components are directly and/or indirectly connected to the negative ion component N.

In order to fully humidify and warm the dry and cold air inhaled during breathing training, a hydrogel component is also included. The hydrogel component can be placed in the external breathing cavity and/or breathing training passage; Part of the water vapor will condense on the surface of the hydrogel component, and part of the heat will be absorbed by the hydrogel body. When inhaling, the water will evaporate again and the heat will be released and mixed into the low-temperature dry airflow.

In order to inhale other gases that are beneficial to health during breathing training, the device is also equipped with at least one external fluid interface, which can be connected to oxygen, hydrogen, helium and other medical gas pipelines and the output pipeline of the atomization device.

For the sake of appearance, it also includes a sheet-like face shell that is buckled onto the respiratory training device during use, and the elastic unit and the straps of the fixing device can be connected to the face shell.

The beneficial effects of the present invention are:

1. The inner cavity of the gas filter component is fluidly connected to the breathing training path. The inhaled and exhaled gases are purified by the gas filter component and then enter the human respiratory tract or the external environment to ensure two-way protection during inhalation and exhalation; and the gas has a three-dimensional structure The filter component doubles the area of the gas filter component in a limited space, ensuring the purification effect while minimizing the air resistance during inhalation or exhalation.

2. Only by replacing the breathing training component and the gas barrier component, you can achieve independent exhalation training, inhalation training, or simultaneous exhalation training and inhalation training, and the air resistance required for training can be adjusted according to the tick mark. The gear position can be changed at any time according to the user's needs, and the operation is simple and convenient.

3. The periphery of the proximal opening of the ventilation terminal component conforms to the facial skin. Oral breathing training, nasal breathing training, or simultaneous breathing training of the mouth and nose can be used. The breathing training device is wearable and is not affected by the user. Depending on the environment, breathing training can be performed while sitting, lying, standing or even walking.

4. The ventilation terminal component is connected with an elastic unit. The elastic unit can deform and/or shift accordingly due to the movement of the skin in the facial area, thus realizing the ventilation terminal component's contact with the skin in the facial area when mouth breathing training causes temporomandibular joint movement. Dynamic sealing ensures respiratory protection during training.

5. The breathing training device is connected to a negative ion component including electronic supply components, which can provide a more stable, continuous and high-concentration supply of negative ions. The content of pure negative ions generated in the purified air can reach up to millions per cubic centimeter, avoiding particulate matter. The additional damage caused by combining with negative ions, only pure negative ions can better play a beneficial biological role in the human body.

6. The hydrogel component designed by the bionic nasal mucus blanket is adsorbed to the outer respiratory cavity. The saturated water vapor exhaled by the user is rehydrated on the surface of the hydrogel component and evaporates when inhaling; when exposed to dry and cold air, it continues to evaporate. Humidify and warm the inhaled air. When encountering hot and humid air, the hydrogel absorbs moisture and heat to dehumidify and cool down.

The opposite is true when exhaling; the breathing training component 2 includes a hollow passage component 21 and a matching resistance adjustment component 22. When used together, the two form a breathing training path 20. The breathing training path 20 is provided with a distal opening 202 and a proximal opening 201. , the distal opening 202 of the breathing training passage 20 of the breathing training component 2 is in fluid communication with the inner cavity 10 of the gas filter assembly, and the proximal opening 201 of the breathing training passage 20 is connected with the respiratory opening 0; as shown in Figures 1A-1C, it also includes a ventilation terminal Component 3, the distal opening 32 of the ventilation terminal component 3 is connected with the proximal opening 201 of the respiratory training passage 20. In this example, the tubular connection portion 35 of the ventilation terminal component 3 is sealed and sleeved in the tubular protrusion 203 on the passage component 21; ventilation The proximal opening 31 of the terminal component 3 is connected with the respiratory tract opening 0, and a ventilation inner cavity 30 is formed between the distal opening 32 and the proximal opening 31. The ventilation terminal component 3 can be an independent component or can be connected with the gas filter assembly 1 and/or the respiratory tract. The training assembly 2 is connected into one body. In this embodiment, the ventilation terminal component 3 is an independent component. The gas filter assembly inner cavity passage 100 extends from the auxiliary component 12 of the gas filter assembly 1. The breathing training passage 20 is connected to the gas filter assembly inner cavity. The passage 100 is fluidly connected and sealed; when inhaling, the external ambient air is purified by the gas filter component 11 of the gas filter assembly 1 and enters the inner cavity passage 100 of the gas filter assembly, then enters the breathing training passage 20, and finally passes through the ventilation inner cavity. 30 flows into the respiratory tract opening 0 to complete an inhalation training process; when exhaling, the gas exhaled by the human body first enters the ventilation inner cavity 30, then enters the inner cavity 10 of the gas filter assembly through the breathing training passage 20, and finally passes through the gas filter After purification, component 11 enters the external ambient air to complete an exhalation training process without causing particulate matter pollution to the environment; the thin arrow lines in Figures 1B and 1C are the gas flow lines during inhalation training.

As shown in Figures 1D-1F, the breathing training component 2 in this embodiment is composed of a passage component 21, a resistance adjustment component 22 and a positioning component 24. After being assembled into one body, as shown in Figure 1F, when the resistance adjustment component 22 of the breathing training component 2 rotates It can be relatively displaced with the passage component 21 to adjust the air resistance during exhalation training and/or inhalation training; the hollow passage component 21 and the resistance adjustment component 22 are used together to form a distal opening 202 and a proximal opening 201 The breathing training channel 20 has an arc-shaped airflow adjustment port 210 located in the breathing training channel 20.

The conformable shielding part 223 is arc-shaped and matches the airflow adjustment port 210 distributed in an arc shape; the resistance adjustment component 22 passes through the through hole 212 on the passage component 21 and is connected to the positioning component 24, which can be connected by bonding or welding. It is integrated; ensuring that the resistance adjustment component 22 will not break away from the passage component 21 during rotation; during rotation, the conformable shielding portion 223 on the resistance adjustment component can adjust the air inlet and outlet cross-sectional area of the airflow adjustment port 210 through circular motion to adjust the breathing resistance. , the left side of Figure 1D shows that the indicator convex point 211 is located at the "1" position of the scale line S. At this time, the arc-shaped air flow adjustment port 210 is not blocked by the conformable shielding part 223, and the air inlet and outlet cross-sectional area of the air flow adjustment port 210 is the largest. , the air resistance is minimal during inhalation and/or exhalation training. The right side of Figure 1D shows that after the resistance adjustment component 22 is rotated counterclockwise, the indicator bump 211 is located at the "6" position of the scale line S. At this time, the arc The shaped airflow adjustment port 210 is partially blocked by the conformable shielding part 223, which reduces the air inlet and outlet cross-sectional area and increases the air resistance during inhalation and/or exhalation training.

As shown in Figure 1G, in this embodiment, the gas filter assembly 1 is composed of a gas filter component 11 and an auxiliary component 12, which are sealed and connected. The internal space of the channel tube 122 on the auxiliary component 12 is the gas filter component inner cavity passage 100.

The surface area of the component 11 is larger than the cross-sectional area of the distal opening 202 of the breathing training channel 20, which reduces the resistance when the gas passes through the gas filter component 11 to the minimum, so that the air resistance during breathing training is only or mainly based on the cross-sectional area of the air flow adjustment port 210. It changes with the change, reducing the influence of the resistance of the gas filter component 11 on the resistance adjustment range of the breathing training, and the air resistance adjustment of the breathing training is more accurate.

Example 2:

As shown in Figures 2A-2E, what is different from Embodiment 1 is that it also includes a gas barrier component 5 that allows gas to flow in one direction. As shown in Figure 2B, the main channel component 51 of the hollow gas barrier component 5 is provided with a gas flow port. 50. The gas flow port 50 is covered by a deformable gas barrier component 52, and the gas flow port 50 is connected with the inner cavity 10 of the gas filter assembly; when used to train the inhalation function, the gas barrier component 52 on the gas barrier component 5 is deformed. deformation, the gas flow port 50 is opened when exhaling, and the gas is exhaled with almost no resistance, and is closed when inhaling; and when used to train the exhalation function, the gas flow port 50 on the corresponding gas barrier component 5 is It closes when exhaling and opens when inhaling (figure omitted); this embodiment shows a schematic structural diagram of the gas barrier component when training the inhalation function. The breathing training device includes a gas filter assembly 1 with a gas filter assembly inner cavity 10, The auxiliary component 12 of the gas filter assembly 1 extends out two channel tubes 122, which are simultaneously connected to a breathing training component 2 and a gas barrier component 5. The internal spaces of the channel tubes 122 form a first inner cavity passage 100a and a second inner cavity passage 100b respectively. , can be respectively connected with the breathing training passage 20 of the breathing training component 2 or the gas flow port 50 of the gas barrier component 5, and also includes a ventilation terminal part 3, the ventilation inner cavity 30 of the ventilation terminal part 3, the breathing training passage 20 and the gas flow port 50 At the same time, the fluid is connected; Figure 2A shows a schematic diagram of the gas filter component 1, the respiratory training component 2 and the ventilation terminal component 3 when they are separated, and Figure 2B shows a schematic diagram of the gas filter component 1, the respiratory training component 2 and the ventilation terminal component 3 after they are combined. When the user inhales, the external air is purified by the gas filter component 11 of the gas filter assembly 1 and enters the second inner cavity passage 100b, then enters the ventilation inner cavity 30 through the breathing training passage 20, and finally enters the lungs through the human respiratory tract opening. When the user exhales, the gas flow port 50 of the gas barrier component 5 is open, and the gas exhaled by the human body is almost All the gas enters the first inner cavity passage 100a through the gas flow port 50, and then is purified by the gas filter component 11 of the gas filter assembly 1 before entering the external environment. The thin arrowed line in Figure 2B is the gas flow path during exhalation. .

As shown in Figures 2C and 2D, the structural schematic diagrams of the breathing training component 2 and the gas barrier component 5 are shown.

The left and right rotation operation can cause the resistance adjustment component 22 and the passage component 21 to undergo relative displacement, which can change the position of the scale line S corresponding to the indicating convex point 211, thereby changing the arc shape. The ventilation cross-sectional area of the air flow adjustment port 210 is used to adjust the air resistance during breathing training; the left side of Figure 2D is a cross-sectional view of the gas barrier component 5. It can be seen that the gas barrier component 5 in this example is a one-way air valve structure, and the gas barrier component 5 is formed by the main body. The channel component 51 is composed of an air flow blocking component 52. The main channel component 51 is provided with a gas flow port 50 that can be covered by the air flow blocking component 52. The air flow blocking component 52 is located on the side of the main channel component 51 away from the ventilation inner cavity of the ventilation terminal component 3. (See Figures 2B and 2D), the airflow blocking component 52 is composed of a soft plastic sheet, which can be deformed by the impact of the airflow and then deflected; when inhaling, the airflow blocking component 52 tightly covers the gas flow port 50 to prevent gas from passing through, ensuring Gas can only enter the respiratory tract through the breathing training passage 20. When exhaling, as shown in Figure 2B, the air flow blocking component 52 is deflected due to the air flow impact part, causing the gas flow port 50 to open. Almost all exhaled gas passes through the gas flow port with low resistance. 50 outflow to ensure the purpose of simple inhalation training.

As shown in Figure 2E, the gas filter assembly 1 is made up of a gas filter component 11 and an auxiliary component 12 that are sealed and connected. The auxiliary component 12 of the gas filter component 1 extends out two channel tubes 122, forming a first inner cavity passage 100a and a second inner cavity passage 100a. In the inner cavity passage 100b, the gas filter component 11 is supported and shaped by the auxiliary component 12 of the dendritic three-dimensional support structure. The surface area of the gas filter component 11 is much larger than the cross-sectional area of the distal opening 202 of the respiratory training channel 20. The resistance of the gas filter component itself is The resistance adjustment range for breathing exercises has almost no effect.

Example 3:

As shown in Figures 3A-3C, what is different from Embodiment 2 is that this embodiment illustrates training the exhalation function. The gas barrier assembly 5 is composed of a main body channel component 51 and an air flow blocking component 52. The air flow blocking component 52 is located in the main body channel component 51. The side close to the ventilation inner cavity 30 of the ventilation terminal component 3 (see Figures 3B and 3C); when exhaling, the air flow blocking component 52 tightly covers the gas flow port 50 so that the gas cannot pass through, ensuring that the gas can only pass through the breath during exhalation. The training channel 20 enters the external environment (not shown). When inhaling, as shown in FIG. 3C , the airflow blocking member 52 is deflected due to the airflow impact portion, causing the gas flow port 50 to open. Almost all the inhaled gas is from the gas with low resistance. The flow port 50 passes through, and there is almost no resistance when inhaling, thereby ensuring the purpose of simple exhalation training.

Specifically, the auxiliary component 12 of the gas filter assembly 1 extends out two channel tubes 122 to form a first lumen passage 100a and a second lumen passage 100b. The first lumen passage 100a and the second lumen passage 100b are disposed at the same time. On a gas filter assembly 1, and at the same time connected with the inner cavity 10 of the gas filter assembly, the first inner cavity passage 100a is connected with the gas flow port 50 of the gas barrier assembly 5, and the second inner cavity passage 100b is connected with the breathing training of the breathing training assembly 2 The passages 20 are connected; when the user exhales, the exhaled gas enters the breathing training passage 20 from the ventilation inner cavity 30, then enters the gas filter assembly inner cavity 10 through the second inner cavity passage 100b, and is finally purified by the gas filter component 11 Enter the external environment and complete an exhalation training; when the user inhales, as shown in Figure 3C, the gas flow port 50 of the gas barrier component 5 is opened, and the air purified by the gas filter component 11 enters the first inner cavity The passage 100a then enters the ventilation inner cavity 30 through the gas flow port 50, and finally enters the human respiratory tract. The thin arrowed line in Figure 3C is the gas flow path during inhalation.

Example 4:

As shown in Figures 4A-4C, what is different from Embodiment 1 is that the breathing training component 2 includes a hollow passage component 21 and a resistance adjustment component 22 used in conjunction with it. The resistance adjustment component 22 is composed of a rotating body 221 and an adjusting body 222. When the operating part 221a of the rotating body 221 is rotated, the adjusting body 222 can be displaced up and down. The distance between the top surface 2221 of the adjusting body 222 and the bottom end surface 511 of the main channel component 51 of the gas barrier assembly 5 changes, that is, the cross-sectional area through which the gas flows. Change, causing the air resistance of the gas to flow into the respiratory opening through the breathing training passage 20 to change, that is, to achieve the purpose of breathing training, a sealing ring L is provided around the bottom end of the passage component 21 to ensure the seal between the rotating body 221 and the passage component 21. Prevent gas leakage.

As shown in Figure 4A, the distal opening 202 of the breathing training passage 20 of the breathing training component 2 is in fluid communication with the inner cavity 10 of the gas filter assembly, and the proximal opening 201 of the breathing training passage 20 is in fluid communication with the distal opening 32 of the ventilation terminal component 3. Ventilation The proximal opening 31 of the terminal component 3 is connected with the respiratory tract opening 0 (the inner cavity 10 of the gas filter assembly and the respiratory tract opening 0 are not shown). At this time, the gas barrier component 5 is only composed of the main channel component 51 provided with the gas flow port 50, and the gas barrier The component 5 is placed in the hollow passage component 21. The distance between the bottom end surface 511 of the main passage component 51 and the top surface 2221 of the adjustment body 222 can change due to the up and down movement of the adjustment body 222; during breathing training, the user can adjust the appropriate resistance in advance. gear, when inhaling, the external ambient air is purified by the gas filter component 11 and enters the breathing training passage 20 through the distal opening 202, then enters the ventilation inner cavity 30 through the proximal opening 201, and finally enters the human respiratory tract. When exhaling , the gas exhaled by the human body flows into the breathing training passage 20 through the ventilation inner cavity 30, and then flows into the gas filter assembly inner cavity 10 through the distal opening 202, and finally enters the external environment after being purified by the gas filter assembly 11, that is, a breath is completed. Gas training and an inhalation training, the thin arrowed line in Figure 4A is the gas flow path during inhalation (the inner cavity 10 of the gas filter assembly is omitted).

As shown in Figures 4B and 4C, a variation of Embodiment 4 is that the breathing training component 2 includes two hollow passage parts 21, which cooperate with the resistance adjustment parts 22 to form two independent breathing training passages 20. The breathing training passages 20 are respectively connected with gas barrier components 5. The gas barrier component 5 is composed of a main channel component 51 and an air flow barrier component 52. The main channel component 51 is provided with a gas flow port 50 that can be covered by the air flow barrier component 52. The air flow barrier component 52 It is composed of a soft plastic sheet that can be deflected by the impact of airflow when the gas passes through it. The airflow blocking component 52 in the left breathing training channel 20 is located above the main channel component 51, that is, on the side close to the ventilation inner cavity 30. The gas flow port 50 can only be opened when inhaling. The airflow blocking component 52 in the right breathing training channel 20 is located below the main channel component 51, that is, on the side away from the ventilation inner cavity 30. The gas flow port 50 can only be opened when exhaling; this The unique design can perform exhalation training and inhalation training at the same time, and different resistance gear values can be set during exhalation training and inhalation training. For example, larger gas resistance is required during exhalation training and higher gas resistance is required during inhalation training. If the gas resistance is small, the rotating body operating part 221a of the resistance adjusting member 22 can be rotated respectively to move the adjusting body 222 up and down, so that the top surface 2221 of the left adjusting body 222 is in contact with the main body channel member 51 of the left gas barrier assembly 5. The distance between the end surfaces 511 increases, so that the distance between the top surface 2221 of the right adjustment body 222 and the bottom end surface 511 of the main body channel component 51 of the right gas barrier assembly 5 decreases, that is, the gas flows through the left respiratory training channel. The resistance of 20 is smaller and the resistance flowing through the right breathing training passage 20 is larger, so as to achieve the training purpose of large air resistance during exhalation and small air resistance during inhalation. The two thin lines with arrows on the left and right in Figure 4C respectively represent inhalation. The lines through which gases flow during inhalation and exhalation.

Connected, the air flow blocking component 52 is located on the side of the main body channel component 51 close to the outer breathing chamber 00. The gas blocking component 5 is closed when exhaling and opened when inhaling (see Figure 5D); during exhalation training, inhale first, and the external environment The air is purified by the gas filter component 11 and enters the second inner cavity passage 100b, then passes through the outer respiratory cavity 00, and finally enters the human respiratory tract. At this time, the larger gas flow port 50 is almost completely open due to the impact of the air flow, and there is resistance when the gas passes through. Very small; when exhaling, the gas exhaled by the human body enters the outer breathing chamber 00, then enters the first inner chamber passage 100a through the breathing training passage 20 with training resistance, and finally enters the external ambient air after being purified by the gas filter component 11 , the gas flow port 50 is closed during exhalation, and an exhalation training is completed; Figure 5C shows a cross-sectional view of the resistance adjustment component 22, the thin line with an arrow is a line diagram of the gas flow during exhalation, and Figure 5D shows a cross-sectional view of the gas barrier Sectional view of component 5.
