[0001] This invention relates to the field of rehabilitation training technology, and in particular to a lung function rehabilitation training device. Background Technology

[0002] Respiratory muscles are the muscles involved in breathing movements and are an important source of power for human respiration. The strength of respiratory muscle function directly affects lung function. Through scientific training, in addition to increasing the strength and endurance of respiratory muscles, their function can also be improved.

[0003] However, existing rehabilitation training methods often involve blowing up balloons, which only allows for exhalation exercises and not inhalation exercises; it is also difficult to determine whether the breathing rhythm is relatively even during exhalation / inhalation; moreover, existing rehabilitation training methods are tedious and boring.

[0004] Therefore, there is an urgent need for a lung function rehabilitation training device. Summary of the Invention

The reciprocating component includes a piston assembly and a sleeve. Based on the user's inhalation and exhalation, the gas pressure inside the sleeve is changed, thereby driving the piston assembly to slide inside the sleeve, which in turn moves the transmission plate. This causes the tapping component to move left and right according to the trajectory of the curved slide groove to tap the feedback component. Based on the tapping signal, a breathing rhythm reminder command is sent through a reminder module to assist the user in adjusting a uniform breathing rhythm. The tapping component adds to the fun of the training process.

[0014] Optionally, the axial length of the sleeve is greater than a first distance, which is the straight-line distance between the starting point and the ending point of the curved groove.

[0015] Optionally, when the striking mallet moves to a specific position, the striking mallet contacts the feedback member;

A breathing rhythm reminder command is sent through the reminder module to help the user adjust a uniform breathing rhythm. The combination of the striking component and the feedback component increases the fun of the training process. Attached Figure Description

[0042] The terms “and / or” or “and / or” include all combinations of any one or more of the listed items.

[0043] like Figure 1 As shown, the present invention provides a lung function rehabilitation training device, including: a reciprocating component 1, a transmission plate 2, a trainer base 3, a percussion component 4, and a feedback component 5;

[0044] One end of the reciprocating component 1 is used for inhaling and / or exhaling gas, and the other end of the reciprocating component 1 is fixedly connected to one end of the transmission plate 2; the upper surface of the transmission plate 2 is provided with a curved groove 21; the lower surface of the transmission plate 2 is slidably connected to the trainer base 3; the striking component 4 includes a striking element and a sliding column 42 arranged vertically, the end of the sliding column 42 is accommodated in the curved groove 21, and the sliding column 42 drives the striking element to move; the orthographic projection of the length direction of the striking element on the transmission plate 2 is not parallel to the sliding direction of the transmission plate 2, and the length direction of the striking element is not perpendicular to the upper surface of the transmission plate 2; the feedback component 5 is fixed on the trainer base 3, and the striking surface of the feedback component 5 is adapted to the striking end of the striking element.

[0045] Respiratory muscles are the muscles involved in breathing movements and are an important source of power for human respiration. The strength of respiratory muscle function directly affects lung function. Like our skeletal muscles, respiratory muscles can also become fatigued after being stimulated by exercise, and may even lead to respiratory muscle failure. By exercising using scientific methods to enhance the strength and endurance of respiratory muscles, their function can be improved.

[0046] The existing rehabilitation training models for respiratory muscle function are: 1. Abdominal breathing. 2. Pursed-lip breathing.

[0047] When performing the above breathing methods, it is necessary to adjust the breathing rate and prolong the breathing time.

[0048] In respiratory rehabilitation training, inhalation and exhalation exercises are the primary training methods. However, the common "blowing up balloons" method only trains exhalation and not inhalation. Furthermore, this method cannot determine the evenness of the breathing rhythm, thus failing to improve training effectiveness; the simple process of inhalation and exhalation is also rather monotonous. Therefore, this invention provides a lung function rehabilitation training device, specifically:

[0049] The trainer base 3 includes a base support 33 and a tray 31. The tray 31 is located on the upper surface of the base support 33 and is fixedly connected to the base support 33. When the transmission plate 2 moves on the tray 31, relative displacement between the tray 31 and the base support 33 is avoided, which would affect the effect of the training device. Of course, the base support 33 and the tray 31 can also be integrally formed.

[0050] The transmission plate 2 is slidably connected to the trainer base 3; specifically, the lower surface of the transmission plate 2 is slidably connected to the trainer base 3. To limit the movement of the transmission plate 2, a linear groove 311 is provided on the support plate 31, and the transmission plate 2 is slidably connected within the linear groove 311. The length direction of the linear groove 311 is the sliding direction of the transmission plate 2, and blocking elements are provided at both ends of the linear groove 311 to prevent the transmission plate 2 from sliding out of the linear groove 311. Figure 2 As shown in one embodiment of this specification, the pallet 31 is a rectangular plate, and the length direction of its straight groove 311 is parallel to the X-axis direction. That is, the moving direction of the transmission plate 2 is parallel to the X-axis direction, where the X-axis direction is the direction of the straight line connecting the midpoint of the front side and the midpoint of the rear side of the pallet 31. The Y-axis direction is the direction of the straight line connecting the midpoint of the left side and the midpoint of the right side of the pallet 31. The X-axis direction is perpendicular to the Y-axis direction; both the X-axis and Y-axis directions are parallel to the upper surface of the transmission plate 2; and the Z-axis direction is perpendicular to the upper surface of the transmission plate 2. In use, the device of the present invention is preferably placed on a horizontal plane, with the transmission plate 2 parallel to the horizontal plane; in this case, both the X-axis and Y-axis directions are parallel to the horizontal plane; and the Z-axis direction is perpendicular to the horizontal plane.

[0051] The linear slide 311 has two end positions: the end position furthest from the push rod 111 is the termination position of the linear slide 311; and the end position closest to the push rod 111 is the initial position of the linear slide 311. The structure of the push rod 111 will be described later.

[0052] In one embodiment of this specification, the linear groove 311 includes: a first groove and a second groove that are parallel to each other and not on the same horizontal plane. The first groove is located above the second groove, and the cross-section of the first groove is larger than the cross-section of the second groove. The length of the first groove is the same as the length of the second groove.

[0053] The transmission plate 2 includes a first transmission part and a second transmission part, wherein the first transmission part is located above the second transmission part. Of course, the first and second transmission parts can be integrally formed. When the transmission plate 2 is slidably connected in the linear slide groove 311, the first transmission part is located in the first slide groove, and the second transmission part is located in the second slide groove. To maintain the balance of the transmission plate 2, the second transmission part is located at the bottom center of the first transmission part.

[0054] Preferably, the cross-section of the linear slide 311 is straight, i.e., "I" shaped, and the longitudinal section of the linear slide 311 is "T" shaped. The longitudinal section of the transmission plate 2 is also "T" shaped. The cross-sectional dimensions of the transmission plate 2 are adapted to the linear slide 311 to prevent the transmission plate 2 from sliding outside the support plate 31.

[0055] The upper surface of the transmission plate 2 is provided with a curved groove 21, wherein the bottom of the striking member 4 is located within the curved groove 21, and the moving direction of the striking member 4 is perpendicular to the moving direction of the transmission plate 2. Specifically, the striking member 4 moves in the Y-axis direction. More specifically, the top surface (upper surface) of the first transmission part of the transmission plate 2 is provided with a curved groove 21.

[0056] like Figure 3 As shown, the curved slide 21 includes several first slides 211 and several second slides 212, wherein adjacent first slides 211 and second slides 212 are connected, and the curves of the first slides 211 and the second slides 212 are centrally symmetrical about the connection point between the first slides 211 and the second slides 212.

[0057] Preferably, the number of first slides 211 and second slides 212 is the same.

[0058] Regarding the determination of the cross section of the curved slide 21, firstly, the first trajectory of the first slide segment 211 is constructed. Taking the end point of the first trajectory as the reference point, the first trajectory is centrally symmetrical to generate the second trajectory of the second slide segment 212. In this slide segment, the first trajectory and the second trajectory are centrally symmetrical about the reference point.

[0059] The initial trajectory of the curved chute 21 is determined by summarizing all the first and second trajectories in sequence. Within this initial trajectory, the first spacing and the second spacing are equal. The first spacing is the shortest distance between adjacent peaks and valleys on the X-axis, and the second spacing is the shortest distance between adjacent valleys and peaks on the X-axis, so that the striking frequency of the striking member 4 is consistent when the transmission plate 2 moves at a constant speed.

[0060] Then, taking the initial trajectory as one side of the cross section, the width of the curved groove 21 is determined according to actual needs, and thus the shape of the cross section is determined.

[0061] When the striking component 4 strikes the feedback component 5, the sliding column 42 of the striking component 4 is exactly located at the position corresponding to the peak / valley value of the initial trajectory of the curved slide 21. At this time, the striking component 4 and the feedback component 5 come into contact. Preferably, the cross-section of the curved slide 21 is located in the middle of the transmission plate 2.

[0062] In one embodiment of this specification, the first trajectory is a straight line with a continuously decreasing or increasing trend. Specifically, if the first trajectory is a straight line with a continuously decreasing trend, then the second trajectory is a straight line with a continuously increasing trend. Conversely, if the first trajectory is a straight line with a continuously increasing trend, then the second trajectory is a straight line with a continuously decreasing trend. In this case, the initial trajectory of the curved chute 21 is a broken line, and within this broken line, the first spacing and the second spacing are equal.

[0063] In another embodiment of this specification, the first trajectory is an arc, exhibiting a continuous downward or upward trend. Specifically, if the first trajectory is an arc with a continuous downward trend, then the second trajectory is an arc with a continuous upward trend. Conversely, if the first trajectory is an arc with a continuous upward trend, then the second trajectory is an arc with a continuous downward trend. In this case, the initial trajectory of the curved groove 21 is a wavy line, and within this wavy line, the first spacing and the second spacing are equal.

[0064] In other embodiments of this specification, the first trajectory may also be a curve of other shapes, which are not specifically limited here.

[0065] The curved slide has two endpoints: the endpoint furthest from the push rod 111 is the initial position of the curved slide 21, and the endpoint closest to the push rod 111 is the ending position of the curved slide 21.

[0066] Feedback component 5 is fixed to the trainer base 3, and the striking surface of feedback component 5 is adapted to the striking end of the striking element. Preferably, feedback component 5 is detachably connected to the trainer base 3. To facilitate the installation of feedback component 5, at least one side of the support plate 31 is connected to a support frame 32, and the arrangement direction of the support frame 32 and the support plate 31 is parallel to the moving direction of the transmission plate 2. That is, the support plate 31 and the support frame 32 are spaced apart, and the support frame 32 is located on at most two sides of the support plate 31, with the two sides facing each other.

[0067] Considering that the striking component 4 does not move back and forth relative to the trainer base 3 in the sliding direction of the transmission plate 2, that is, the striking component 4 does not move in the X-axis direction, it is not necessary to set multiple feedback components 5 on the same support frame 32.

[0068] Considering that the number of the support frames 32 is one or two, preferably, the feedback component 5 includes one or two feedback members 51. The feedback members 51 are perpendicular to the horizontal plane, and at most one feedback member 51 is installed on each support frame 32.

[0069] In an embodiment of the present specification, a support frame 32 is installed on the left side or the right side of the pallet 31. At this time, the number of the feedback members 51 is one. When there is a support frame 32 on the left side of the pallet 31, the feedback member 51 is located on the left side of the pallet 31; when there is a support frame 32 on the right side of the pallet 31, the feedback member 51 is located on the right side of the pallet 31.

[0070] In another embodiment of the present specification, support frames 32 are installed on both the left side and the right side of the pallet 31. At this time, the number of the feedback members 51 can be one or two. Specifically, when the number of the feedback members 51 is one, the feedback member 51 is installed on one of the support frames 32. At this time, there is no feedback member 51 on the other support frame 32. When the number of the feedback members 51 is two, one feedback member 51 is installed on the support frame 32 on the left side of the pallet 31, and the other feedback member 51 is installed on the support frame 32 on the right side of the pallet 31. At this time, the two feedback members 51 are arranged oppositely.

[0071] In an embodiment of the present specification, the support frame 32 includes a first support frame 321 and two second support frames 322. Among them, the first support frame 321 and the second support frames 322 are both located on the same horizontal plane; the first support frame 321 is parallel to the sliding direction of the transmission plate 2, the second support frames 322 are perpendicular to the sliding direction of the transmission plate 2, and the two second support frames 322 are parallel; one end of the second support plate is connected to the side surface of the pallet 31, and the other end of the second support plate is connected to one end of the first support frame 321, thereby forming a "C"-shaped support structure.

[0072] As Figure 4 shown, in an embodiment of the present specification, the feedback member 51 is a percussion drum. The percussion drum includes a percussion drum body 511 and a percussion drum frame 512. The percussion drum body 511 is located above the percussion drum frame 512. The bottom of the percussion drum frame 512 is detachably installed on the support frame 32. Preferably, the percussion drum frame 512 can be clamped on the first support frame 321. If there is one percussion drum on each of the two support frames 32, the drum surfaces of the two percussion drum bodies 511 are opposite to each other. Among them, the drum surface of the percussion drum body 511 is the striking surface of the feedback component. During the process of using this device for rehabilitation training, the percussion component 4 strikes the percussion drum body 511 based on the breathing frequency of the user. While effectively strengthening the diaphragmatic function of the user, the user can adjust the breathing rhythm based on the actual striking frequency, thereby making the breathing training rhythmic; the rhythmic percussion also increases the interest of the breathing training to a certain extent.

[0073] The striking component 4 is slidably connected to the trainer base 3. Specifically, the striking component 4 includes a striking piece and a sliding column 42 arranged vertically. The end of the sliding column 42 is accommodated in a curved groove 21, and the sliding column 42 drives the striking piece to move. Specifically, the striking piece includes one or two striking mallets 41; the striking end of the striking mallet 41 contacts the striking surface of the feedback component 5; the connecting end of the striking mallet 41 is connected to the head end of the sliding column 42; the end of the sliding column 42 extends vertically into the curved groove 21.

[0074] During a prolonged exhalation or inhalation by the user, in order for the slide column 42 to contact the initial position and the end position of the curved slide groove 21, the distance between the striking member 4 and the rear end of the support plate 31 is greater than or equal to the length of the transmission plate 2 in the Y-axis direction; the distance between the striking member 4 and the front end of the support plate 31 is greater than or equal to the length of the transmission plate 2 in the Y-axis direction; preferably, the striking member 4 is located in the middle of the support plate 31, and the length of the support plate 31 in the Y-axis direction is greater than or equal to twice the length of the transmission plate 2 in the Y-axis direction.

[0075] The training device base 3 is provided with at least one fixed seat 312, the number of fixed seats 312 being the same as the number of striking pestles 41; a through hole is provided on the fixed seat 312, and one striking pestle 41 is slidably connected in one through hole; when there are two striking pestles 41, the transmission plate 2 is located between the two fixed seats 312. Figure 5 As shown, in one embodiment of this specification, the upper surface of the tray 31 is provided with two fixed seats 312, and the linear slide 311 is located between the two fixed seats 312; wherein, one striking pestle 41 passes through one through hole and the other striking pestle 41 passes through another through hole, so that the slide 42 is located between the two through holes, and the length of the striking pestle 41 is greater than the distance between the two through holes, so as to prevent the striking pestle 41 from moving excessively to the left or right and disengaging from the trainer base 3.

[0076] The length direction of the striking pestle 41 is parallel to the upper surface of the transmission plate 2; the length direction of the striking pestle 41 is perpendicular to the sliding direction of the transmission plate 2, that is, the axial direction of the through hole is perpendicular to the length direction of the linear groove 311. The length direction of the striking pestle 41 is perpendicular to the striking surface of the feedback member 5. When there are two fixed seats 312, the arrangement direction of the two fixed seats 312 is not parallel to the sliding direction of the transmission plate 2. The arrangement direction of the two fixed seats 312 is perpendicular to the sliding direction of the transmission plate 2.

[0077] To facilitate feedback on the movement speed of the striking mallet 41, the axis of the striking mallet 41 is at the same height as the axis of the striking drum body 511, so that the striking mallet 41 can smoothly strike the center position of the striking drum body 511, avoiding the inability to recognize the striking signal due to the height difference between the two being too high or too low, and thus the inability to confirm whether the striking was successful.

[0078] When the striking pestle 41 moves to a specific position, the striking pestle 41 contacts the feedback member 5; the specific position is the inflection point of the first slide 211 and / or the inflection point of the second slide 212; the inflection point of the first slide 211 includes the position on the first slide 211 where the distance to the edge of the transmission plate 2 is the shortest; the inflection point of the second slide 212 includes the position on the second slide 212 where the distance to the edge of the transmission plate 2 is the shortest.

[0079] To ensure that the force exerted by the striking mallet 41 on the striking drum body 511 is constant each time, the third spacing and the fourth spacing are equal. The third spacing is the shortest distance between the peak value on the curved groove 21 and the striking drum body 511 in the Y-axis direction; the third spacing is the shortest distance between the valley value on the curved groove 21 and the striking drum body 511 in the Y-axis direction.

[0080] To facilitate replacement of the striking mallet 41, the striking mallet 41 is detachably connected to the sliding column 42. The detachable connection methods include, but are not limited to, snap-fit ​​and threaded connection.

[0081] To prevent the striking mallet 41 from breaking the striking drum body 511 and to reduce wear on parts, buffer sleeves 43 are fitted on both ends of the striking mallet 41.

[0082] To facilitate the movement of the drive plate 2, a reciprocating component 1 is provided; one end of the reciprocating component 1 is used for inhaling and / or inhaling gas, and the other end of the reciprocating component 1 is fixedly connected to one end of the drive plate 2. Specifically, the reciprocating component 1 includes a piston assembly 11 and a sleeve 12; one end of the sleeve 12 is used for inhaling and / or inhaling gas; one end of the piston assembly 11 is slidably connected inside the sleeve 12; and the other end of the piston assembly 11 is fixedly connected to one end of the drive plate 2. In one embodiment of this specification, the piston assembly 11 is located on the rear side of the support plate 31.

[0083] To facilitate increasing or decreasing the gas pressure within the sleeve 12, a conduit 13 is also included. To ensure the hygiene of the conduit 13, one end of the conduit 13 is connected to a breathing mask / breathing filter, and the other end of the conduit 13 is connected to the inlet end of the sleeve 12. The user inhales or exhales gas into the conduit 13 through the breathing mask / breathing filter, thereby causing a change in the gas pressure within the sleeve 12. Based on the gas pressure within the sleeve 12, the piston assembly 11 slides within the sleeve 12, driving the transmission plate 2 to move. This causes the striking component 4 to move left and right relative to the trainer base 3 according to the trajectory of the curved groove 21, thereby striking the feedback component 5.

[0084] Specifically, the reciprocating component 1 includes a piston assembly 11 and a sleeve 12; such as Figure 6As shown, one end of the piston assembly 11 is located inside the sleeve 12, and the other end of the piston assembly 11 extends out of the sleeve 12 and is fixedly connected to the transmission plate 2. Specifically, the piston assembly 11 includes a piston plate and a push rod 111;

[0085] The piston plate is located inside the sleeve 12, and the push rod 111 and the guide tube 13 are located on both sides of the piston plate respectively; one end of the push rod 111 is fixedly connected to the piston plate, and the other end of the push rod 111 passes through the outlet end of the sleeve 12 and is fixedly connected to the transmission plate 2.

[0086] To prevent the transmission plate 2 from jamming due to uneven force when sliding on the support plate 31, the push rod 111 is connected to the midpoint of the side of the transmission plate 2, that is, the center line of the push rod 111 coincides with the center line of the transmission plate 2.

[0087] In one embodiment of this specification, the length of the push rod 111 is greater than the maximum travel distance, so that the slide column 42 can contact the initial position and the end position of the curved slide 21, facilitating the user to perform a longer exhalation or a longer inhalation. The maximum travel distance refers to the difference between the length of the straight slide 311 and the length of the support plate 31 in the Y-axis direction.

[0088] At this time, the length of the sleeve 12 must also be greater than the maximum moving distance in order to prevent the piston plate from sliding out of the sleeve 12 when the user inhales.

[0089] To prevent the push rod 111 from failing to smoothly push / pull back the transmission plate 2, thus causing damage to the push rod 111, the extension direction of the push rod 111 coincides with the axial direction of the sleeve 12. The axial direction of the sleeve 12 is parallel to the moving direction of the transmission plate 2; the axial length of the sleeve 12 is greater than the first distance; the first distance is the straight-line distance between the starting point and the ending point of the curved slide 21.

[0090] In order to limit the axial direction of the sleeve 12 and prevent the sleeve 12 from breaking, an extension member 6 is also included; one end of the extension member 6 is connected to the trainer base 3, and a through hole is provided on the extension member 6 for the sleeve 12 to pass through.

[0091] Specifically, the extension member 6 includes a first extension member 61 and a second extension member 62. The second extension member 62 has a support hole, the axis of which is parallel to the horizontal plane. A sleeve 12 passes through the support hole, and its outer circumferential surface contacts the support hole to fix its position. In one embodiment of this specification, one end of the first extension member 61 is connected to the rear side of the support plate 31, and the other end of the first extension member 61 is connected to the second extension member 62. In another embodiment of this specification, one end of the first extension member 61 is provided with a support portion for support on the ground, and the other end of the first extension member 61 is connected to the second extension member 62. Preferably, the height of the first extension member 61 can be adjusted. By adjusting the height of the first extension member 61, the height of the sleeve 12 in the support hole can be adjusted, thereby ensuring that the height of the push rod 111 in the sleeve 12 is on the same horizontal plane as the height of the support plate.

[0092] During pulmonary rehabilitation training, users need to be trained to breathe evenly. However, individual respiratory flow rates vary, and even under the same conditions, different people will have different breathing frequencies and depths. Simply relying on the user's respiratory flow rate to judge and improve breathing rhythm is highly subjective. Without established standards / reminders, users may find it difficult to train themselves to achieve the predetermined breathing rhythm, and thus may not be able to effectively achieve the intended training results.

[0093] Considering that setting up a speed sensor and speed display terminal to adjust the user's breathing rate would require the user to constantly focus on the speed display terminal, it might distract them and thus affect the effectiveness of breathing training. Furthermore, prolonged focus on changes on the display screen could cause eye strain, and the screen settings are not user-friendly for users with poor eyesight. In addition, using a speed sensor might increase the user's stress and anxiety, as they would need to constantly adjust their breathing to match the precise speed indication on the display terminal.

[0094] Therefore, in order to reduce interference with users and make breathing training more quantifiable and controllable, such as Figure 7 As shown, this device also includes: a signal receiving module, a central processing unit, and an alert module;

[0095] The central processing unit is communicatively connected to the signal receiving module and the reminder module; the central processing unit is also electrically connected to the power supply.

[0096] The signal receiving module is located inside the feedback component 5, the central processing unit is installed on the trainer base 3, and the reminder module is installed on the upper surface of the trainer base 3.

[0097] The system receives the user's inhalation or exhalation of air at one end of the 12 sleeves. Based on the gas pressure, it drives the transmission plate 2 to move back and forth. During the back and forth movement of the transmission plate 2 relative to the trainer base 3, the sliding column 42 moves left and right relative to the trainer base 3 based on the curved sliding groove 21 on the transmission plate 2. In turn, the sliding column 42 drives the striking pestle 41 to move. During the movement, the striking pestle 41 contacts the feedback component 5, generating a striking signal. The signal receiving module captures the striking signal and sends it to the central processing unit for processing. Based on the processing result, the central processing unit controls the reminder module to send a breathing rhythm reminder command to the user.

[0098] A signal receiving module is used to receive the striking signal from the feedback member 5; wherein, the signal receiving module is installed around the feedback member 5. Alternatively, the signal receiving module is installed inside the striking drum body 511 to facilitate the determination of the striking signal based on the vibration frequency. In one embodiment of this specification, a striking signal is generated when the striking mallet 41 strikes the striking drum body 511.

[0099] The reminder module is used to send a breathing rhythm reminder command based on the tapping signal. In one embodiment of this specification, the reminder module is a light flasher 7, and a person skilled in the art sets the flashing frequency of the light flasher 7 and determines the default interval t between two adjacent flashes. In another embodiment of this specification, the reminder module is a metronome, and a person skilled in the art sets the beat frequency of the metronome and determines the default interval t between two adjacent beats.

[0100] Taking the reminder module as an example, which is the light flasher 7:

[0101] When the central processing unit receives the first tap signal, it activates the light flasher 7 based on preset conditions, causing the light flasher 7 to flash at a set frequency. The color of the flashing light can be manually configured. If the central processing unit does not receive another tap signal within a preset time period T after receiving the tap signal, it prompts the user to reset the transmission plate 2 and turns off the light flasher 7. The preset time period T can be set as needed.

[0102] Regarding the preset conditions: First, determine whether the light flasher 7 is in the on state. If the light flasher 7 is in the on state, no further processing is required; if the light flasher 7 is not in the on state, then start the light flasher 7 according to the initial interval time.

[0103] Regarding the determination of the initial interval time: Determine if the starting point of the initial trajectory is a peak / valley value. If the starting point of the initial trajectory is a peak or a valley value, the initial interval time is equal to the default interval time. That is, when the central processing unit receives the first tap signal, the light flasher 7 is activated after interval time t. If the starting point of the initial trajectory is neither a peak nor a valley value, the initial interval time is equal to half of the default interval time. That is, when the central processing unit receives the first tap signal, the light flasher 7 is activated after interval time t. Next, activate the light flasher 7.

[0104] The user's breathing rate is trained by flashing the light flasher 7, ensuring that the frequency of the tapping of the drum by the tapping pestle 41 matches the frequency of the light flasher 7. Since the light flasher 7 requires minimal user attention, the user can see the flashing light only in their peripheral vision during inhalation or exhalation. In one embodiment of this specification, different colored lights flash to remind the user to adjust when the frequency of the tapping of the drum by the tapping pestle 41 matches the frequency of the light flasher 7, the frequency of the tapping of the drum by the tapping pestle 41 is greater than the frequency of the light flasher 7, or the frequency of the tapping of the drum by the tapping pestle 41 is less than the frequency of the light flasher 7.

[0105] Regarding reset: Resetting the transmission plate 2 means moving the transmission plate 2 to its default position. The default position refers to the position of the transmission plate 2 when the piston plate is retracted to its maximum extent. In one embodiment of this specification, the default position includes the position of the transmission plate 2 when it contacts the initial position of the linear slide groove 311.

[0106] Regarding the position of the light flasher 7: In one embodiment of this specification, the light flasher 7 is mounted on the upper surface of the tray 31, near the front side of the tray 31, and perpendicular to the horizontal plane.

[0107] To allow users to more clearly understand their breathing rate, in one embodiment of this specification, the number of light flashers 7 is the same as the number of feedback components 5. That is, one light flasher 7 is provided in each striking drum. At this time, when the central processing unit receives the first striking signal, it determines the source of the striking signal based on the signal receiving module, and activates the light flasher 7, causing the light flasher 7 to flash according to the flashing frequency.

[0108] Regarding reminding the user to reset the transmission plate 2, in one embodiment of this specification, a flashing light of another color can be used by a flashing light device 7 to indicate this.

[0109] This device is designed to help users conduct rehabilitation training to achieve a respiratory volume of 30L / min-90L / min, corresponding to a respiratory rate of 60-180 breaths / min. The optimal requirement is a respiratory volume of 60L / min, corresponding to a respiratory rate of 120 breaths / min. Professionals can set the rhythm of the reminder module based on this, so that users can gradually improve their breathing capacity, lung function, and promote physical recovery by using this device.

[0110] Considering that the slower the user's breathing rate, the smaller the distance the transmission plate 2 moves per unit time, and the longer the interval for receiving the tapping signal; and the faster the user's breathing rate, the greater the distance the transmission plate 2 moves per unit time, and the shorter the interval for receiving the tapping signal.

[0111] With a fixed length of linear chute 311, pressure components 8 are also provided to accommodate different breathing rates and allow users at different stages to customize their rehabilitation training plans according to their own actual rhythm.

[0112] like Figure 8 As shown, the pressure component 8 includes a first swing arm 81, a second swing arm 82, a first connecting member, a second connecting member 83, a resistance adjusting member, and a resistance adjusting switch;

[0113] The first swing arm 81 is parallel to the horizontal plane, and its length direction is parallel to the Y-axis direction. An open third slide groove 811 is provided on the first swing arm 81, with its length direction aligned with that of the first swing arm 81. The cross-section of the third slide groove 811 is rectangular. The first connecting member includes a first slide rod, one end of which is connected to the bottom of the transmission plate 2, and the other end of which extends into the third slide groove 811. In one embodiment of this specification, one end of the first slide rod is connected to the midpoint of the bottom of the second transmission unit; the two can be detachably connected, and the specific connection method is not specifically limited here.

[0114] To ensure that the first swing arm 81 remains parallel to the Y-axis during movement, the first connecting member also includes a first limiting member. The first limiting member is fixedly connected to the first sliding rod. Specifically, the first limiting member has a "U"-shaped cross-section and includes an anti-detachment plate and two limiting plates. The anti-detachment plate is located outside the third sliding groove 811, and the anti-detachment plate and the transmission plate 2 are located on opposite sides of the third sliding groove 811. The anti-detachment plate is perpendicular to the limiting plates and is positioned between the two limiting plates. The two limiting plates are parallel and opposite to each other to clamp the first swing arm 81 and restrict its rotation.

[0115] The second swing arm 82 is located on the base bracket 33. Specifically, the base bracket 33 is located at the bottom of the bracket. The base bracket 33 includes a first bracket 331 and two second brackets 332. The first bracket 331 and the two second brackets 332 are all located in the same plane, and this plane is perpendicular to the horizontal plane. The first bracket 331 is located between the two second brackets 332. The first bracket 331 is parallel to the horizontal plane, and the second brackets 332 are perpendicular to the horizontal plane. That is, the two second brackets 332 are parallel. At this time, one end of the second bracket 332 is connected to the bottom of the pallet 31, and the other end of the second bracket 332 is connected to one end of the first bracket 331, thus forming a "C"-shaped bracket structure.

[0116] Among them, the first bracket 331 is parallel to the moving direction of the transmission plate 2, and the first bracket 331, the linear chute 311 and the transmission plate 2 are vertically centered, that is, arranged in the Z-axis direction. At this time, in the Y-axis direction, the midline of the first bracket 331 and the midline of the linear chute 311 are located in the same plane, and this plane is perpendicular to the horizontal plane.

[0117] One end of the second swing arm 82 is rotatably connected to the midpoint of the first bracket 331, and the second swing arm 82 can rotate about the midpoint of the first bracket 331.

[0118] The other end of the second swing arm 82 and one end of the first swing arm 81 are rotationally matched through a second connecting member 83. Specifically, a first mounting hole is provided at one end of the first swing arm 81, and a second mounting hole is provided at the other end of the second swing arm 82. The first mounting hole and the second mounting hole are coaxially arranged. The second connecting member 83 includes a rotating shaft and two anti-detachment pieces. The rotating shaft passes through the first mounting hole and the second mounting hole, and one anti-detachment piece is connected to each end of the rotating shaft. The diameter of the anti-detachment piece is larger than the aperture of the first mounting hole, and the diameter of the anti-detachment piece is larger than the aperture of the second mounting hole to prevent the rotating shaft from detaching from the first mounting hole and the second mounting hole. Preferably, the aperture of the first mounting hole is equal to the aperture of the second mounting hole.

[0119] The first swing arm 81 and the second swing arm 82 are located on the same side of the first bracket 331. The length of the third slide groove 811 is greater than or equal to half the length of the second slide groove. The second swing arm 82 is greater than or equal to half the length of the second slide groove. In one embodiment of this specification, when the length of the third slide groove 811 is equal to the length of the second slide groove and the second swing arm 82 is equal to half the length of the second slide groove, the length of the third slide groove 811 is twice the length of the second swing arm 82. To save space, in another embodiment of this specification, the length of the third slide groove 811 is equal to half the length of the second slide groove. When the second swing arm 82 is equal to half the length of the second slide groove, the length of the third slide groove 811 is equal to the length of the second swing arm 82. During a full exhalation and inhalation, the first slide bar can move from one end of the third slide groove 811 to the other end of the third slide groove 811.

[0120] The resistance adjustment switch is communicatively connected to the central processing unit and to the resistance adjustment element.

[0121] Considering that respiratory muscles include intercostal muscles, diaphragm, abdominal wall muscles, sternocleidomastoid muscle, back muscles, and chest muscles, among others, the diaphragm is the most important respiratory muscle, responsible for over 70% of the body's respiration. Setting different resistance levels can assist in training to strengthen the diaphragm. Therefore, an adjustable resistance value is added as a controllable indicator for rehabilitation training. Specifically, different resistance levels are set, each corresponding to a different resistance level. The resistance is adjusted based on the user's or other personnel's selection of the resistance adjustment switch.

[0122] In order to achieve resistance adjustment, in one embodiment of this specification, the resistance adjustment member is located in the side wall of the third slide groove 811, and the moving speed of the transmission plate 2 is limited by adjusting the friction force in the third slide groove 811.

[0123] In another embodiment of this specification, the resistance adjusting member is located on the outer periphery of the second connecting member 83, and the moving speed of the transmission plate 2 is limited by adjusting the friction of the second connecting member 83. Specifically, the resistance adjusting member abuts against the rotating shaft, and the friction between the resistance adjusting member and the rotating shaft is adjusted by a resistance adjusting switch.

[0124] In another embodiment of this specification, the resistance adjusting member is located between the first swing arm 81 and the second support 332, and the elastic force between the first swing arm 81 and the second support 332 is adjusted by a resistance adjusting switch. Specifically, the resistance adjusting member is located in the middle of the first swing arm 81 and near the second support 332 of the conduit 13, or the resistance adjusting member may be located in the middle of the first swing arm 81 and away from the second support 332 of the conduit 13. The resistance adjusting member includes two resistance adjusting parts, one of which is located in the middle of the first swing arm 81 and near the second support 332 of the conduit 13, and the other of which is located in the middle of the first swing arm 81 and away from the second support 332 of the conduit 13.

[0125] As mentioned earlier, when the flashing light 7 is turned off, the user can be reminded to reset the transmission plate 2. However, if the user has already discarded their breathing mask / filter, they will need to use a new mask / filter to inhale through the catheter 13 to reset the transmission plate 2, potentially wasting consumables. If the user directly pushes the transmission plate 2 to reset it, improper force can easily damage the device. Therefore, the central processing unit is communicatively connected to the resistance adjustment switch. When the flashing light 7 is turned off, the central processing unit sends a reset command to the resistance adjustment switch. Based on the reset command, the resistance adjustment switch applies a spring force towards the sleeve 12 to the first swing arm 81, causing the first swing arm 81 to move the transmission plate 2 towards the sleeve 12.

[0126] The device of the present invention is based on the gas pressure inside the sleeve 12. By driving the piston assembly 11 to slide inside the sleeve 12, it drives the transmission plate 2 to move, so that the striking component 4 moves left and right relative to the trainer base 3 according to the trajectory of the curved slide groove 21. When moving left and right, the striking component 4 strikes the feedback component 5 to generate a striking signal. Based on the striking signal, a breathing rhythm reminder command is sent through the reminder module to help the trainee adjust a uniform breathing rhythm. The setting of the striking component 4 and the feedback component 5 increases the fun of the training process.

[0127] The working principle is briefly described below:

[0128] The transmission plate 2 and the conduit 13 are located at the two ends of the sleeve 12, that is, one end of the conduit 13 is connected to the breathing filter or breathing mask / breathing filter, and the other end of the conduit 13 is connected to the sleeve 12.

[0129] When the user exhales through one end of the tube 13, the gas volume inside the sleeve 12 increases. Based on the gas pressure, the piston plate inside the sleeve 12 moves towards the outlet end, which in turn drives the push rod 111 to push the transmission plate 2, causing the transmission plate 2 to move away from the tube 13. At this time, the slide column 42 moves left and right relative to the base of the trainer based on the trajectory change of the slide groove on the transmission plate 2, thereby driving the striking pestle 41 to strike the striking drum.

[0130] When the user inhales through one end of the conduit 13, the gas volume inside the sleeve 12 decreases, causing the piston to move away from the outlet end. Based on the gas pressure, the piston plate moves towards the inlet end, which in turn drives the push rod 111 to pull back the transmission plate 2, causing the transmission plate 2 to move towards the conduit 13. At this time, the slide column 42 moves left and right based on the trajectory change of the slide groove on the transmission plate 2, thereby driving the striking pestle 41 to strike the striking drum.

[0131] Based on the user's inhalation and exhalation, the transmission plate 2 reciprocates on the support plate 31. Specifically, the transmission plate 2 moves back and forth relative to the trainer base 3.

[0132] When the signal receiving module receives the striking signal of the striking mallet 41 striking the striking drum, it sends it to the central processing unit. The central processing unit determines whether the light flasher 7 is in the on state. If it is, no processing is required; if not, the light flasher 7 is activated based on preset conditions, so that the light flasher 7 flashes according to the flashing frequency.

[0133] When the central processing unit does not receive a new tap signal within a preset time period, it reminds the user to reset the transmission plate 2; and / or, the central processing unit sends a reset command to the resistance adjustment switch, which pushes the transmission plate 2 to the default position by adjusting the elastic force of the resistance adjustment element.

[0134] The central processing unit shuts down the light flasher 7.

[0135] During use, trainees can select the appropriate level using the resistance adjustment switch based on their actual training situation, so that the resistance adjustment device can be adjusted to the corresponding resistance for personalized training.

[0136] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the present invention is not inherently related to any specific computer, virtual device, or electronic device, and various general-purpose devices can also implement the present invention.
