Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a sputum expectoration auxiliary training device. Background Technology

[0002] Because patients with respiratory diseases have impaired lung ventilation and gas exchange, their ability to cough up phlegm is weakened, making it difficult to expel phlegm. Therefore, regularly clearing the lungs and expelling phlegm is a very important step in the treatment of respiratory diseases. After the phlegm is expelled, the patient's airway can be kept open, thereby reducing the possibility of infection and slowing the progression of the disease.

[0003] Current methods for promoting sputum expectoration primarily utilize oscillatory exhalation to generate high-frequency airflow, creating a vibrational effect that loosens the sputum and facilitates its expulsion. Specifically, patients use training-assisted expectoration devices to expel sputum. By blowing air into the device, the airway vibrates, loosening the sputum, which is then expelled during coughing. Existing training-assisted expectoration devices include:

[0004] case;

[0005] The breathing tube has a breathing chamber inside and two openings: one is the exhalation port, located on one side of the breathing tube and communicating with the breathing chamber, and the other is the breathing port, located at one end of the breathing tube and communicating with the breathing chamber. The patient inhales and exhales through the breathing port.

[0006] A piston assembly is located above the breathing tube. The piston assembly includes a piston rod and a piston rod base. The piston rod has a protruding plug, a rotating part, and a magnetic component mounting part. The rotating part and the magnetic component mounting part are located on both sides of the plug. The plug matches the exhalation port and is movably connected to the exhalation port. The rotating part is rotatably mounted on the piston rod base, which is located on the housing. The rotating part divides the piston rod into a first moving part and a second moving part. The first moving part and the second moving part can rotate around the rotating part.

[0007] A magnetic attraction assembly is located in the first moving part. The magnetic attraction assembly includes a magnetic component, a magnet, and a magnet base. The magnetic component is placed in the magnetic component placement part, the magnetic base is placed on the piston rod base, and the magnet is placed on the magnet base and located below the magnetic component. In the initial state, under the action of magnetic attraction force, the magnetic component tends to move towards the magnet, so that the magnetic component placement part tends to drive the first moving part to move towards the piston rod base, while the second moving part is located away from the piston rod base.

[0008] When a patient exhales through the breathing port into the breathing tube, the magnetic force between the magnetic component and the magnet causes the gas to drive the stopper to separate from and contact the exhalation port, resulting in vibration of the stopper. This vibration, in turn, drives the rotating part to rotate around the piston rod base, repeating the cycle. During this process, the rotating part and the stopper cause the air in the breathing cavity to vibrate, further causing the cilia in the patient's thoracic airway to resonate. This increases the amplitude of the cilia's movement, loosening the sputum adhering to them and promoting its expulsion.

[0009] As the vibration frequency of the rotating part increases, the expectoration effect is better. However, because different patients have different exhalation forces, the frequency of vibration of the rotating part varies. This means that for some patients with weak exhalation forces, the magnetic component cannot be driven to move away from the magnet. As a result, the training-assisted expectoration device is not suitable for all people, causing inconvenience in its use. Utility Model Content

[0010] In view of this, the present invention provides a sputum suction training device to solve the problem that existing training sputum suction devices are not applicable to all groups of people, resulting in inconvenience in the use of training sputum suction devices.

[0011] In a first aspect, this utility model provides a sputum expectoration assistance training device, comprising:

[0012] A first base, with a first channel on one side, a breathing port at one end of the first channel communicating with the outside, and a second channel on the first base, with one end of the second channel communicating with the other end of the first channel;

[0013] A rocker unit is disposed above the second channel. The rocker unit includes a first moving part, a second moving part, and a hinge part disposed between the first moving part and the second moving part. The hinge part is rotatably connected to the first base. The first moving part and the second moving part can move away from or towards the first base in opposite directions relative to the hinge part. A sealing member is provided on the side of the second moving part near the second channel. The sealing member has a first state of sealing the second channel and a second state of opening the second channel.

[0014] The first magnetic unit is located on the side of the second moving part near the first base;

[0015] The second magnetic unit is movably connected to the first base. The second magnetic unit is correspondingly arranged with the first magnetic unit. The second magnetic unit and the first magnetic unit have magnetic attraction so that the seal is in a natural state of the first state and the seal is driven to a second state by exhalation force. The first magnetic unit is in a use state that is far away from the second magnetic unit. In the natural state and the use state, the second magnetic unit and the first magnetic unit are always spaced apart.

[0016] An adjustment unit is rotatably connected to the first base. The adjustment unit includes a spiral lifting structure, and the distance between the spiral line of the spiral lifting structure and the center point of the spiral lifting structure is equal everywhere. The adjustment unit is connected to the second magnetic unit. The adjustment unit is used to rotate under the drive of an external force to drive the second magnetic unit to move closer to or further away from the first magnetic unit.

[0017] Beneficial effects: When not in use, the first and second magnetic units are in their natural magnetic attraction state, and the seal is in the first state. When using this sputum expectoration aid training device, the user blows air into the breathing port. The exhalation force drives the seal to switch between the first and second states, and further drives the first and second moving parts to reciprocate around the hinge. That is, when the second moving part moves away from the first base and the first moving part moves towards the first base, the second moving part can drive the first magnetic unit to change from its natural magnetic attraction state to a state where the first and second magnetic units move away from each other. This cycle repeats, which can increase the amplitude of the cilia in the chest airway, loosening the sputum adhering to the cilia in the chest airway, thereby promoting the expectoration of sputum.

[0018] During this process, the second magnetic unit can be moved closer to or further away from the first magnetic unit by rotating the adjustment unit. When the user begins use the device, rotating the adjustment unit to move the second moving part away from the first base results in the greatest distance between the second and first magnetic units, at which point the magnetic force between them is weakest. For patients with weak expiratory strength, this allows the second magnetic unit to switch between its natural and active states. For users with better expiratory strength, rotating the adjustment unit to move the second moving part away from the first base creates a suitable distance between the second and first magnetic units. Based on this, the sputum clearance training device can be adapted to different patients, thus improving its applicability.

[0019] In one alternative embodiment, the adjustment unit is located on one side of the second magnetic unit.

[0020] In one optional embodiment, the adjustment unit has a drive groove on the side near the second magnetic unit, the drive groove forming the spiral lifting structure, and one end of the second magnetic unit is disposed in the drive groove.

[0021] Beneficial effects: Because the drive groove has a spiral lifting structure, the minimum distance between each point on the bottom of the drive groove and the first base is different. Therefore, the distance between the first and second magnetic units can be adjusted by rotating the adjustment unit to move the second magnetic unit closer to or away from the first magnetic unit.

[0022] In one alternative embodiment, the adjustment unit is rotatably connected between the second magnetic unit and the first base.

[0023] In one optional embodiment, the adjustment unit has a first protrusion at one end near the second magnetic unit, the first protrusion forming the spiral lifting structure, and the second magnetic unit is provided on the first protrusion.

[0024] Beneficial effect: By adjusting the rotation of the unit, different positions of the first protrusion can be driven to contact the second magnetic unit, thereby adjusting the distance between the first and second magnetic units according to the user's needs.

[0025] In one optional implementation, the adjustment unit includes:

[0026] The adjustment body has a first protrusion and a hollow part on its inner side, through which a second channel is passed.

[0027] Beneficial effects: Based on the hollow part, not only can the conflict between the setting position of the main body and the position of the second channel be avoided, but the internal structure of the sputum expectoration auxiliary training device can also be improved, thereby achieving the technical effect of improving the portability of the sputum expectoration auxiliary training device.

[0028] In one alternative implementation, the weight of the second moving part is greater than the weight of the first moving part;

[0029] And / or, the sputum expectoration assistance training device includes:

[0030] A blocking unit is disposed in the first channel to divide the first channel into a first flow area and a second flow area along the axial direction. The second flow area is connected between the first flow area and the second channel. A cross-section is made along the axis perpendicular to the first channel, and the cross-sectional area of ​​the first flow area is larger than that of the second flow area.

[0031] Beneficial effects: When the second moving part moves away from the first base, the distance between the first magnetic unit and the second magnetic unit is the farthest. At this time, the attraction between the first magnetic unit and the second magnetic unit is the weakest. Under the gravity of the second moving part, it can also be ensured that the second moving part moves towards the first base, avoiding the second magnetic unit being unable to attract the first magnetic unit, thus affecting the use of the sputum expectoration auxiliary training device.

[0032] The blocking unit can adjust the effective flow area of ​​the first and second flow areas, and define the cross-section along the axis perpendicular to the first channel. The size of the first flow area is larger than that of the second flow area, so that when the gas in the first flow area passes through the connection between the first and second flow areas, the gas flow speed in the second flow area is accelerated, the vibration frequency of the rocker unit is increased, the vibration frequency of the air in the first channel is increased, and the loosening of sputum is further accelerated, thereby achieving the technical effect of improving sputum expectoration efficiency.

[0033] In one optional embodiment, a cross-section is taken along an axis perpendicular to the first channel, and the ratio between the cross-sectional area of ​​the second flow region and the cross-sectional area of ​​the first flow region is in the range of 1 / 3 to 1 / 2.

[0034] And / or, the length of the first flow area along its axial direction is within the range of 1.5cm-3cm.

[0035] Beneficial effects: When a cross-section is taken along the axis perpendicular to the first channel, the ratio between the cross-sectional area of ​​the second flow area and the cross-sectional area of ​​the first flow area is within the range of 1 / 3 to 1 / 2. Based on this, it avoids a situation where the difference between the cross-sectional areas of the second and first flow areas is too large when taking a cross-section perpendicular to the first channel, which would require the user to exert a large expiratory force to drive the separation between the first and second magnetic units, thus increasing the difficulty of using the sputum expectoration auxiliary training device. The sputum expectoration auxiliary training device of this invention achieves the technical effect of reducing the difficulty of using the sputum expectoration auxiliary training device.

[0036] Furthermore, the length of the first flow area along its axis is within the range of 1.5cm-3cm. This avoids excessive length of the first flow area, which could lead to energy loss of expiratory force and prevent water vapor in the exhaled air from accumulating on the inner walls of the first and second channels, affecting the vibration amplitude of the rocker unit and further influencing its vibration frequency. This, in turn, improves the sputum clearance efficiency of the sputum clearance assistive training device.

[0037] In one optional embodiment, a third channel is provided on the other side of the first base. The third channel is connected to both the first channel and the second channel. An airflow control structure is provided in the third channel to control the flow direction of gas so that it enters the first channel only through the third channel.

[0038] Beneficial effects: By setting up a third channel and an airflow control structure, the user can inhale through the breathing port. The airflow control structure ensures that gas enters the first channel only through the third channel, preventing gas from the first channel from passing to the outside through the third channel and affecting the amount of gas entering the second channel from the first channel. This achieves the technical effect of improving the sputum expectoration efficiency of the sputum expectoration auxiliary training device.

[0039] In one alternative embodiment, the ratio between the distance between the breathing port and the airflow control structure and the length of the first flow area along its axial direction is in the range of 3 / 2 to 5 / 2.

[0040] Beneficial effects: By limiting the ratio between the distance between the breathing port and the airflow control structure and the length of the first flow area along its axis, the length of the first flow area along its axis is prevented from being too large, which would result in greater friction between the exhaled gas and the inner wall of the first channel, causing energy loss of the exhaled gas. This reduces the force acting on the rocker unit, lowers the air vibration frequency, and reduces the sputum expectoration effect of the sputum expectoration auxiliary training device.

[0041] In one optional embodiment, the sputum expectoration assistance training device includes:

[0042] The pipeline includes at least three connection ends. The first connection end of the pipeline is connected to one end of the first channel (101), the second connection end of the pipeline serves as the breathing port, and the third connection end of the pipeline is used to communicate with the outside.

[0043] Beneficial effects: In practical use, the third connection end of the pipeline can be connected to an external gas flow meter to monitor the gas flow in the first channel in real time, thereby monitoring the user's breathing data and facilitating the adjustment of the distance between the first magnetic unit and the second magnetic unit based on the breathing data.

[0044] In one optional embodiment, the sputum expectoration assistance training device includes:

[0045] The second base is located between the rocker unit and the first base. The hinge is rotatably connected to the second base. The second base has a pipe at the position where it communicates with the second channel. The seal is in a state of being fitted with the opening of the pipe, so that the seal has a first state of being sealed and connected to the second channel, or the seal is in a state of being separated from the opening of the pipe, so that the seal has a second state of being separated from the second channel.

[0046] Beneficial effect: By setting a second base, the contact position between the second base and the seal can be adjusted to be smaller than the sealing area required by the seal for the second channel, thereby improving the ease of sealing of the seal.

[0047] In one alternative embodiment, the pipe is frustum-shaped, the bottom diameter of the pipe is smaller than the top diameter of the pipe, and the opening of the pipe is located at the top of the pipe;

[0048] And / or, the seal is conical in shape and is sealed to the top of the pipe. Attached Figure Description

[0071] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0072] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0073] According to an embodiment of the present invention, a sputum expectoration assistance training device is provided, comprising:

[0074] The first base 1 has a first channel 101 on one side, and a breathing port connected to the outside at one end of the first channel 101. The first base 1 has a second channel 102, and one end of the second channel 102 is connected to the other end of the first channel 101.

[0075] The rocker unit 2 is located above the second channel 102. The rocker unit 2 includes a first moving part 201, a second moving part 202, and a hinge part located between the first moving part 201 and the second moving part 202. The hinge part is rotatably connected to the first base 1. The first moving part 201 and the second moving part 202 can move away from or towards the first base 1 in opposite directions relative to the hinge part. A sealing member 203 is provided on the side of the second moving part 202 near the second channel 102. The sealing member 203 has a first state of sealing the second channel 102 and a second state of opening the second channel 102.

[0076] The first magnetic unit 3 is disposed on the side of the second moving part 202 near the first base 1;

[0077] The second magnetic unit 4 is movably connected to the first base 1. The second magnetic unit 4 is correspondingly arranged with the first magnetic unit 3. The second magnetic unit 4 and the first magnetic unit 3 have magnetic attraction so that the seal 203 is in the natural state of the first state and the seal 203 is in the second state driven by exhalation force. The first magnetic unit 3 and the second magnetic unit 4 are in the use state of being far apart from each other. The second magnetic unit 4 and the first magnetic unit 3 are always arranged at a distance.

[0078] Adjustment unit 5 is rotatably connected to the first base 1. Adjustment unit 5 includes a spiral lifting structure, and the distance between the spiral line of the spiral lifting structure and the center point of the spiral lifting structure is equal everywhere. The spiral lifting structure is connected to the second magnetic unit 4 and is used to rotate under external force to drive the second magnetic unit 4 to move towards or away from the first magnetic unit 3.

[0079] In this utility model, when the sputum expectoration auxiliary training device is not in use, the first magnetic unit 3 and the second magnetic unit 4 are in a natural state of magnetic attraction, and the sealing member 203 is in the first state. When using the sputum expectoration auxiliary training device, the user blows air into the breathing mouth. The exhalation force can drive the sealing member 203 to switch between the first state and the second state, and further drive the first moving part 201 and the second moving part 202 to reciprocate around the hinge. That is, when the second moving part 202 moves away from the first base 1 and the first moving part 201 moves closer to the first base 1, the second moving part 202 can drive the first magnetic unit 3 to change from a natural state of magnetic attraction with the second magnetic unit 4 to a state of use where the first magnetic unit 3 and the second magnetic unit 4 are far apart. This cycle repeats, which can increase the swing amplitude of the cilia in the chest airway, loosen the sputum adhering to the cilia in the chest airway, and thus promote the expectoration of sputum.

[0080] During this process, the second magnetic unit 4 can be moved closer to or further away from the first magnetic unit 3 by rotating the adjustment unit 5. When the user begins to use the device, rotating the adjustment unit 5 so that the second moving part 202 moves away from the first base 1 results in the greatest distance between the second magnetic unit 4 and the first magnetic unit 3. At this point, the magnetic force between the first magnetic unit 3 and the second magnetic unit 4 is weakest. For patients with weak expiratory strength, this allows the second magnetic unit 4 to switch back and forth between its natural and active states. For users with better expiratory strength, rotating the adjustment unit 5 so that the second moving part 202 moves away from the first base 1 results in a suitable distance between the second magnetic unit 4 and the first magnetic unit 3. Based on this, the sputum clearance assist training device can be applied to different patients, thereby improving the applicability of the device.

[0081] When the second moving part 202 moves away from the first base 1, the closer the distance between the second magnetic unit 4 and the first magnetic unit 3, the better the sputum expectoration effect.

[0082] Furthermore, preferably, the weight of the second moving part 202 is greater than the weight of the first moving part 201. Based on this, when the second moving part 202 moves away from the first base 1, the distance between the first magnetic unit 3 and the second magnetic unit 4 is at its maximum. At this time, the attraction between the first magnetic unit 3 and the second magnetic unit 4 is the weakest. Under the action of gravity, the second moving part 202 can also be ensured to move towards the first base 1, thus preventing the second magnetic unit 4 from failing to attract the first magnetic unit 3 and affecting the use of the sputum expectoration auxiliary training device.

[0083] Of course, in other embodiments, the weight of the second moving part 202 can be equal to the weight of the first moving part 201. By selecting the first magnetic unit 3 and the second magnetic unit 4 with greater attraction, so that when the first magnetic unit 3 and the second magnetic unit 4 are at their farthest distance apart, there is still an attraction between the first magnetic unit 3 and the second magnetic unit 4, so as to ensure that the second moving part 202 can move towards the first base 1 and drive the air in the first channel 101 and the second channel 102 to vibrate.

[0084] In addition, combined Figure 1 and Figure 4 As shown, in this embodiment, the second magnetic unit 4 includes:

[0085] Magnetic structure 401;

[0086] The connecting structure has a receiving part 404 on one side, and a magnetic structure 401 is provided inside the receiving part 404.

[0087] The transmission structure 403 is connected at one end to the other side of the connecting structure, and at the other end of the transmission structure 403 is connected to the adjustment unit 5.

[0088] The position of the magnetic structure 401 can be defined by the connecting structure, and it can be connected to the adjustment unit 5 by the transmission structure 403, so that the connecting structure and the magnetic structure 401 can move in the direction of approaching or moving away from the first magnetic unit 3.

[0089] Preferably, the magnetic structure 401 is detachably connected to the receiving portion 404 so that the magnetic structure 401 can be replaced as needed.

[0090] Specifically, the receiving part 404 is provided with a buckle, which allows the magnetic structure 401 to be detachably connected to the receiving part 404. The buckle is a mature technology and will not be described in detail here. As an alternative implementation, the magnetic structure 401 can also be detachably connected to the receiving part 404 by a clamp.

[0091] In addition, combined Figure 1 and Figure 7 As shown, in this embodiment, the sputum expectoration assistance training device includes a guide unit 6, which is located on one side of the first base 1 and on one side of the second magnetic unit 4. The guide unit 6 is movably connected to the transmission structure 403 and is used to limit the movement direction of the second magnetic unit 4. Based on this, it can be ensured that the second magnetic unit 4 moves only along... Figure 1 The second magnetic unit 4 moves in the direction of the Z-axis toward the first magnetic unit 3 or away from the first magnetic unit 3, thereby achieving the technical effect of improving the accuracy of the movement direction of the second magnetic unit 4.

[0092] Among them, the guide rail structure 601 is located along the second magnetic unit 4. Figure 1 On both sides of the X-axis, the guide rail structure 601 is fixedly connected to the first base 1. The guide rail structure 601 is located near the second magnetic unit 4 and has a guide groove 602 along the Z-axis. The connecting structure has a second protrusion 402, which is slidably connected within the guide groove 602. The guide groove 602 allows the second magnetic unit 4 to move linearly along the Z-axis, thus limiting the direction of movement of the second magnetic unit 4. Alternatively, the second protrusion 402 can be omitted, and the connecting structure can be directly slidably connected within the guide groove 602.

[0093] Of course, in other embodiments, a groove along the Z-axis can also be provided on the second magnetic unit 4. In this case, the guide rail structure 601 is a rod-shaped structure, and the groove passes through the rod-shaped structure, which can also achieve the technical effect of limiting the movement direction of the second magnetic unit 4. As an alternative implementation, the guide unit 6 can be connected to the transmission structure 403 by a clamp. When it is necessary to adjust the position of the transmission structure 403, the transmission structure 403 can be disassembled. After determining the position of the transmission structure 403, the transmission unit and the guide unit 6 can be fixed by the clamp.

[0094] In addition, combined Figure 3 As shown, in this embodiment, the sputum expectoration assistance training device includes:

[0095] The blocking unit 7 is disposed in the first channel 101 and is used to divide the first channel 101 into a first flow area 1011 and a second flow area 1012 along the axial direction, that is, along the direction parallel to the Y-axis. The second flow area 1012 connects the first flow area 1011 and the second channel 102. A cross-section is made along the direction perpendicular to the axis of the first channel 101, that is, along the direction parallel to the Z-axis. The cross-sectional area of ​​the first flow area 1011 is larger than the cross-sectional area of ​​the second flow area 1012.

[0096] By setting the blocking unit 7, the effective flow area of ​​the first flow area 1011 and the second flow area 1012 can be adjusted. A cross-section is defined along the axis perpendicular to the first channel 101, with the cross-sectional area of ​​the first flow area 1011 being larger than that of the second flow area 1012. This allows the gas in the first flow area 1011 to accelerate its flow speed in the second flow area 1012 when passing through the connection point between the first flow area 1011 and the second flow area 1012. This increases the vibration frequency of the rocker unit 2, raising the vibration frequency of the air in the first channel 101, further accelerating the loosening of sputum, thereby achieving the technical effect of improving sputum expectoration efficiency. Alternatively, the sputum expectoration auxiliary training device may not include the blocking unit 7.

[0097] Furthermore, in this embodiment, when a cross-section is taken along the axis perpendicular to the first channel 101, the ratio between the cross-sectional area of ​​the second flow region 1012 and the cross-sectional area of ​​the first flow region 1011 is within the range of 1 / 3 to 1 / 2. Based on this, it avoids a situation where, when a cross-section is taken along the axis perpendicular to the first channel 101, the difference between the cross-sectional areas of the second flow region 1012 and the first flow region 1011 is too large, resulting in insufficient air pressure acting on the seal 203. This would require the user to exert a greater expiratory force to drive the separation between the first magnetic unit 3 and the second magnetic unit 4, increasing the difficulty of using the sputum expectoration auxiliary training device. The sputum expectoration auxiliary training device in this embodiment achieves the technical effect of reducing the difficulty of using the sputum expectoration auxiliary training device.

[0098] Furthermore, the length of the first flow area 1011 along its axial direction is within the range of 1.5cm-3cm. Based on this, it is possible to avoid the energy loss of expiratory force caused by the excessive length of the first flow area 1011, and to prevent water vapor in the exhaled air from accumulating on the inner walls of the first channel 101 and the second channel 102, affecting the vibration amplitude of the rocker unit 2, and further affecting the vibration frequency of the rocker unit 2, thereby achieving the technical effect of improving the sputum clearance efficiency of the sputum clearance auxiliary training device.

[0099] Of course, in other embodiments, the cross-section can be limited to the axis perpendicular to the first channel 101, and the ratio between the cross-sectional area of ​​the second flow region 1012 and the cross-sectional area of ​​the first flow region 1011 can be in the range of 1 / 3 to 1 / 2, or the length of the first flow region 1011 along its axial direction can be limited to the range of 1.5cm to 3cm.

[0100] In other embodiments, the sputum expectoration assistive training device may be limited to including the blocking unit 7, or the first magnetic unit 3 and the second magnetic unit 4 may be spaced apart when the seal 203 is in the first state, or the weight of the second moving part 202 may be limited to being greater than the weight of the first moving part 201.

[0101] In other embodiments, depending on the design of the sputum expectoration assist training device, a cross-section can be made along the axis perpendicular to the first channel 101 to adjust the ratio between the cross-sectional area of ​​the second flow area 1012 and the cross-sectional area of ​​the first flow area 1011. At the same time, the length of the first flow area 1011 along its axial direction can be adjusted.

[0102] Furthermore, in this embodiment, the sputum expectoration assistance training device includes:

[0103] The tubing includes three connection ends. The first connection end is connected to one end of the first channel 101, the second connection end serves as a breathing port, and the third connection end is used to connect to the outside. In practical use, the third connection end of the tubing can be connected to an external gas flow meter to monitor the gas flow rate in the first channel 101 in real time, thereby monitoring the user's breathing data and facilitating the adjustment of the distance between the first magnetic unit 3 and the second magnetic unit 4 based on the breathing data.

[0104] In other embodiments, the sputum expectoration assistive training device may not include tubing.

[0105] Preferably, the pipeline is a three-way valve. Of course, in other embodiments, the pipeline can be three interconnected pipes.

[0106] In other embodiments, the number of connection terminals can be adjusted as needed. Alternatively, the third connection terminal can be used to connect to other external devices as needed.

[0107] In addition, combined Figure 1 , Figure 7 and Figure 8 As shown, a third channel 103 is provided on the other side of the first base 1. The third channel 103 is connected to the first channel 101 and the second channel 102. An airflow control structure 104 is provided in the third channel 103 to control the flow direction of the gas so that it enters the first channel 101 through the third channel 103 and cannot flow out of the sputum expectoration auxiliary training device through the third channel 103.

[0108] By setting up a third channel 103 and an airflow control structure 104, the user can inhale through the breathing port. The airflow control structure 104 can ensure that the gas enters the first channel 101 only through the third channel 103, preventing the gas in the first channel 101 from passing to the outside through the third channel 103 and affecting the amount of gas entering the second channel 102 from the first channel 101, thereby achieving the technical effect of improving the sputum expectoration efficiency of the sputum expectoration auxiliary training device.

[0109] The airflow control structure 104 is a one-way valve, which can be used in conjunction with a ventilator as needed. Connecting the ventilator to the one-way valve allows the user to breathe without requiring breathing. Gas from the ventilator flows through the third channel 103 to the second channel 102, which in turn drives the vibration of the rocker unit 2, further assisting the user in expectorating sputum. Alternatively, the airflow control structure 104 can also be a directional control valve.

[0110] Of course, in other embodiments, depending on the design of the sputum expectoration assistance training device, the third channel 103 and the airflow control structure 104 may not be provided.

[0111] Furthermore, preferably, the ratio between the distance between the breathing opening and the airflow control structure 104 and the length of the first flow area 1011 along its axial direction is within the range of 3 / 2 to 5 / 2. Based on this, it is possible to avoid the first flow area 1011 being too long along its axial direction, which would result in excessive friction between the exhaled gas and the inner wall of the first channel 101, causing energy loss of the exhaled gas, reducing the force acting on the rocker unit 2, lowering the air vibration frequency, and thus reducing the sputum expectoration effect of the sputum expectoration auxiliary training device.

[0112] Simultaneously, this avoids the situation where the length of the first flow area 1011 along its axial direction is too small, resulting in an excessively high gas velocity acting on the seal 203. An excessively high gas velocity acting on the seal 203 would cause insufficient expiratory force acting on the seal 203, thus increasing the difficulty of using the sputum expectoration training device. Therefore, this embodiment achieves the technical effect of reducing the difficulty of using the sputum expectoration training device by limiting the range of the ratio between the distance between the breathing port and the airflow control structure 104 and the length of the first flow area 1011 along its axial direction.

[0113] Of course, in other embodiments, the ratio between the distance between the breathing port and the airflow control structure 104 and the length of the first flow area 1011 along its axial direction can be adjusted depending on the design of the sputum expectoration assist training device.

[0114] Furthermore, in this embodiment, a fourth channel 105 with one end connected to the outside is provided below the first base 1. The other end of the fourth channel 105 is connected to the first channel 101, the second channel 102 and the third channel 103. A sealing structure is detachably connected inside the fourth channel 105. The sealing structure is used to adjust the fourth channel 105 to have a state of communication with the outside and a state of non-communication with the outside.

[0115] By disassembling the sealing structure, one end of the fourth channel 105 can be connected to the nebulizer to provide nebulization treatment to the user, softening the phlegm in the user's body, thereby achieving the technical effect of improving phlegm expectoration efficiency.

[0116] When nebulization therapy is not required, the sealing structure can be installed in the fourth channel 105.

[0117] Specifically, the sealing structure can be a rubber plug, with a first thread on the side of the rubber plug and a second thread on the inner wall of the fourth channel 105. The detachable connection between the sealing structure and the fourth channel 105 can be achieved through the threaded connection between the first thread and the second thread.

[0118] Of course, in other embodiments, the detachable connection between the sealing structure and the fourth channel 105 can be adjusted according to the different designs of the sputum expectoration auxiliary training device, for example, the sealing structure and the fourth channel 105 can be interference-fitted.

[0119] In addition, in this embodiment, combined with Figure 1 and Figure 6 As shown, the sputum expectoration assistance training device includes:

[0120] The sputum expectoration training device includes:

[0121] The second base 8 is located between the rocker unit 2 and the first base 1. The hinge is rotatably connected to the second base 8. The second base 8 is provided with a pipe 801 at the position where it connects to the second channel 102. The sealing member 203 is in a state of being in contact with the opening of the pipe 801, so that the sealing member 203 has a first state of being sealed and connected to the second channel 102, or the sealing member 203 is in a state of being separated from the opening of the pipe 801, so that the sealing member 203 has a second state of being separated from the second channel 102.

[0122] By setting a second base 8, the contact position between the second base 8 and the seal 203 can be adjusted to be smaller than the sealing area required by the seal 203 for the second channel 102, thereby achieving the technical effect of improving the ease of sealing of the seal 203.

[0123] In this embodiment, the hinged part is detachably connected to the second base 8 to facilitate the disassembly and cleaning of the rocker unit 2 and the second base 8. Specifically, the second base 8 along... Figure 1 The X-axis direction is shown with slots on both sides. The slot opening size is smaller than the maximum size of the hinge, allowing the largest part of the hinge to be interference-fitted into the slot, improving the stability of the hinge rotation. When it is necessary to clean the rocker unit 2 and the second base 8, external force is applied until the largest part of the hinge disengages from the slot, thus achieving the disassembly of the rocker unit 2 and the second base 8.

[0124] Furthermore, the second base 8 and the first base 1 are detachably connected, so the second base 8 can be disassembled to facilitate cleaning.

[0125] Specifically, the second base 8 and the first base 1 are detachably connected by a snap fastener. This detachable connection method is technically mature and will not be elaborated on here.

[0126] In both the natural and operational states, the second magnetic unit 4 and the first magnetic unit 3 are always spaced apart. Specifically, when the second magnetic unit 4 is in its natural state, the seal 203 is in contact with the opening of the pipe 801, preventing the second magnetic unit 4 from rotating further, thus ensuring that the second magnetic unit 4 and the first magnetic unit 3 are always spaced apart.

[0127] Of course, in other embodiments, a baffle can also be provided on the guide rail structure 601, which can also achieve the same effect of keeping the second magnetic unit 4 and the first magnetic unit 3 in a spaced-out state.

[0128] In other embodiments, the second base 8 is detachably connected to the first base 1 via a clamp, or the second base 8 may be fixedly connected to the first base 1.

[0129] In addition, combined Figure 5 As shown, in this embodiment, the pipe 801 is frustum-shaped, the bottom diameter of the pipe 801 is smaller than the top diameter of the pipe 801, the opening of the pipe 801 is located at the top of the pipe 801, the sealing member 203 is conical, and the sealing member 203 seals the top of the pipe 801. That is, the connection between the sealing member 203 and the top of the pipe 801 is a line connection, while it is spaced apart from the other sides of the pipe 801.

[0130] Of course, in other embodiments, the seal 203 can be fitted to the side of the pipe 801, that is, the connection between the seal 203 and the pipe 801 is a surface connection. Compared with other embodiments, in this embodiment, the gas passing through the second channel 102 only needs to drive the seal 203 and the top of the pipe 801 to be in a separated state, which can reduce the difficulty of the gas driving the seal 203, thereby improving the ease of use of the sputum expectoration auxiliary training device.

[0131] In other embodiments, only the pipe 801 may be defined as frustum-shaped, or only the seal 203 may be defined as conical. Furthermore, the shapes of the pipe 801 and the seal 203 may be adjusted depending on the design of the sputum expectoration aid training device.

[0132] In other embodiments, depending on the design of the sputum expectoration assistive training device, the seal 203 can also be spherical, which can also achieve a fit against the opening of the pipe 801 near the second channel 102.

[0133] In addition, in this embodiment, the first magnetic unit 3 and the second moving part 202 are detachably connected. Therefore, the first magnetic unit 3 can be disassembled as needed. The second moving part 202 has a slot, the opening size of which is smaller than the maximum size of the first magnetic unit 3. This allows the largest portion of the first magnetic unit 3 to be interference-fitted into the slot. External force drives the largest portion of the first magnetic unit 3 to move into the slot. When the second moving part 202 needs to be disassembled, external force drives the first magnetic unit 3 to move out of the slot.

[0134] Of course, in other embodiments, the first magnetic unit 3 may be detachably connected to the second moving part 202 via a clamp, or the first magnetic unit 3 may be fixedly connected to the second moving part 202.

[0135] In addition, preferably, the first base 1 has a gear scale on the surface corresponding to the adjustment unit 5, for example, it has 1-5 gears. The adjustment unit 5 has an alignment scale. By rotating the adjustment unit 5, the alignment scale corresponds to the gear scale. As the gear number increases, it means that the distance between the first magnetic unit 3 and the second magnetic unit 4 is smaller, and the required exhalation force is greater.

[0136] Of course, in other embodiments, gear markings and alignment markings may not be provided.

[0137] Furthermore, in this embodiment, granular protrusions are provided on the contact surfaces between the adjustment unit 5 and the first base 1. Based on this, the friction between the adjustment unit 5 and the first base 1 can be increased, preventing external forces from accidentally touching the adjustment unit 5 and causing the gear adjustment, thereby achieving the technical effect of improving the reliability of the sputum expectoration auxiliary training device.

[0138] In addition, combined Figure 1 As shown, the adjustment unit 5 and the guide unit 6 are located on the same side of the first base 1, that is, the side of the first base 1 where the third channel 103 is located are two sides.

[0139] Combination Figure 1 As shown, compared to the spiral line of the spiral lifting structure in related technologies, the distance between the spiral line and the center point of the spiral lifting structure is not equal. Therefore, the adjustment unit 5 needs to be set on the first base 1 on the same side as the third channel 103. It can be concluded that the contact area between the adjustment unit 5 and the first base 1 in this embodiment is greater than the contact area between the adjustment unit 5 and the first base 1 in related technologies. In this embodiment, the first base 1 can support the adjustment unit 5, thereby achieving the technical effect of improving the stability of the rotation of the adjustment unit 5.

[0140] There are many ways to implement adjustment unit 5. The following describes two specific implementation methods:

[0141] Example 1

[0142] Combination Figure 1 and Figure 4 As shown, in this embodiment, the adjustment unit 5 is located on one side of the second magnetic unit 4.

[0143] At this time, the adjustment unit 5 is provided with a drive groove 501 on the side near the second magnetic unit 4. The drive groove 501 forms a spiral lifting structure, and one end of the transmission structure 403 is located in the drive groove 501.

[0144] Since the drive groove 501 is a spiral lifting structure, the minimum distance between each point on the bottom of the drive groove 501 and the first base 1 is different, that is, along the parallel to Figure 1 As shown in the Z-axis direction, the distances between each point on the bottom of the drive groove 501 and the first base 1 are different. Based on this, the distance between the first magnetic unit 3 and the second magnetic unit 4 can be adjusted by rotating the adjustment unit 5 to move the second magnetic unit 4 in a direction closer to the first magnetic unit 3 or away from the first magnetic unit 3.

[0145] Example 2

[0146] Combination Figure 9 and Figure 10 As shown, in this embodiment, the adjustment unit 5 is rotatably connected between the second magnetic unit 4 and the first base 1.

[0147] Among them, combined Figure 9 and Figure 10 As shown, the adjustment unit 5 has a first protrusion 503 at one end near the second magnetic unit 4. The first protrusion 503 forms a spiral lifting structure, and the second magnetic unit 4 is provided on the first protrusion 503.

[0148] By adjusting the rotation of unit 5, the first protrusion 503 can be driven to contact the second magnetic unit 4 at different positions, thereby adjusting the distance between the first magnetic unit 3 and the second magnetic unit 4 according to the user's needs.

[0149] Since the second channel 102 in this embodiment is located between the first base 1 and the second magnetic unit 4, in order to prevent the adjustment unit 5 from interfering with the second channel 102, the adjustment unit 5 in this embodiment includes:

[0150] Adjustment body 502, adjustment body 502 is provided with a first protrusion 503, adjustment body 502 is provided with a hollow part 504 on the inner side, and a second channel 102 is provided inside the hollow part 504.

[0151] Based on the hollow part 504, not only can the conflict between the setting position of the main body 502 and the position of the second channel 102 be avoided, but the compactness of the internal structure of the sputum expectoration auxiliary training device can also be improved, thereby achieving the technical effect of improving the portability of the sputum expectoration auxiliary training device.

[0152] Of course, in other embodiments, an additional installation space for the adjustment unit 5 can be provided on the first base 1 to prevent the setting position of the adjustment unit 5 from interfering with the setting position of the second channel 102.

[0153] As an alternative implementation, the second magnetic unit 4 may be located above or below the first protrusion 503, and the transmission structure 403 may be located in the groove formed by the first protrusion 503 and one side of the adjustment body 502. This can also achieve the technical effect of driving the second magnetic unit 4 to move in a direction closer to or away from the first magnetic unit 3 by rotating the first protrusion 503.

[0154] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
