Description

Technical Field

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

[0002] For patients with impaired lung function, such as those suffering from clustered pneumonia, chronic obstructive pulmonary disease, bronchial asthma, or emphysema, in the later stages of treatment, in addition to medication, appropriate physical therapy can play a significant supporting role in drug treatment, thereby curing or alleviating lung problems. Pulmonary rehabilitation training devices can be used to train the patient's lungs, thereby improving the quality of care.

[0003] Existing pulmonary function rehabilitation devices aim to improve and rehabilitate lung function by having patients perform inflatable exercises such as blowing air. However, these devices inflate balloons or other inflatable objects during training, and it's difficult to determine whether each breath meets the required standard based solely on experience. Furthermore, the achievable blowing capacity varies at different stages of training. In the early stages, due to poorer lung function, the required blowing standard should be lower. As training progresses, the achievable breathing capacity gradually increases, and the blowing standard in the intermediate and later stages should differ from that in the early stages. Otherwise, it's difficult to provide targeted training based on the patient's lung function. Maintaining the same standard in the later stages leads to suboptimal training results and slower lung function recovery. Therefore, existing pulmonary function rehabilitation devices suffer from difficulty in assessing training effectiveness and a lack of standardized training criteria, resulting in slow rehabilitation outcomes. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a lung function rehabilitation training device to solve the problem that the training standards in the prior art are singular and difficult to distinguish, resulting in slow rehabilitation effects.

[0005] To solve the above-mentioned technical problems, the present invention provides a pulmonary function rehabilitation training device comprising a shell with an internal cylindrical training cavity. A transparent observation window is provided on one side of the shell to facilitate observation of the situation inside the training cavity. A balloon is placed inside the training cavity. A training tube is provided on the shell, one end of which is connected to and communicates with the inner cavity of the balloon. An air nozzle is provided at the other end of the training tube. By blowing air into the air nozzle, the balloon can be inflated to achieve the purpose of training pulmonary function. An exercise grading mechanism is provided inside the training cavity. The exercise grading mechanism includes a suspension plate located directly above and supported on the balloon, and a support part provided on the inner wall of the training cavity. The support part enables the training cavity to have multiple [unclear text - possibly related to exercise grading mechanisms]. The system comprises vertically distributed tiered chambers for supporting the suspension plate. As the balloon inflates and moves upward, the suspension plate can move upward relative to each tiered chamber and be supported within its corresponding position. Thus, as the patient inflates the balloon by blowing air, the balloon expands with each exhalation, gradually increasing in size. The balloon presses against the suspension plate, causing it to rise sequentially into each tiered chamber. This allows the patient to easily observe the position of the suspension plate within its designated chamber through an observation window, enabling them to determine whether the training has reached the required standard and, if so, what standard. Furthermore, the multiple tiered chambers can be used to control training standards at different stages, ensuring that the patient can clearly understand their training progress each time.

[0006] Furthermore, the suspension plate is circular and slides vertically within the training chamber; the support includes multiple first support portions and multiple second support portions mirror-distributed on opposite inner walls of the training chamber, with each first and second support portion equally spaced vertically; each first and second support portion includes a receiving groove recessed into the inner wall of the training chamber and a movable support piece hinged to the bottom of the receiving groove and capable of being stored within the receiving groove, the top of the movable support piece swinging in and out of the receiving groove; the movable support pieces of any two adjacent first support portions and the movable support pieces of any two adjacent second support portions opposite them form the grading chamber, thereby forming multiple grading chambers with different blowing standards. Each grading chamber serves to support the suspension plate while also facilitating observation of the training standard, enabling the rapid acquisition of the required training information.

[0007] Furthermore, a base is formed on the bottom of the movable support piece and on the side near the training cavity. The base supports the bottom wall of the storage groove when the movable support piece is tilted outward. The distance between any two opposite tilted movable support pieces is less than the diameter of the suspension plate, so that the movable support piece remains tilted and the suspension plate can move upward to move into different grading cavities.

[0008] Furthermore, the exercise grading mechanism also includes air cushions corresponding to the inner walls of each grading cavity and used to block the upward movement of the suspension plate, as well as a trigger control unit for compressing the air cushions when the balloon expands. The trigger control unit expands the air cushions when the balloon contracts, so that when the shell may tip over due to collisions or other reasons, the suspension plate may move into other grading cavities and affect the normal training progress because the movable support plates are not in the preset state. The air cushions can prevent this problem when the shell tip over.

[0009] Furthermore, each of the air cushion portions includes at least three airbags arranged circumferentially along the inner wall of the training chamber. An air passage is formed within the housing to connect the airbags. The trigger control unit is connected to the air passage. When the balloon inflates and squeezes the trigger control unit, the trigger control unit creates negative pressure in the air passage, causing the airbag to contract. When the balloon contracts and moves away from the trigger control unit, the trigger control unit pressurizes the air passage to inflate the airbag and block the suspension plate. Thus, the state of the airbag is automatically controlled according to the state of the balloon to achieve the purpose of limiting the suspension plate.

[0010] Furthermore, the trigger control unit includes a fixing block fixedly connected to the inner wall of the training chamber and a pressing part. A sliding cavity is formed between the fixing block and the shell. A ventilation hole penetrating the shell is formed on the side of the sliding cavity away from the training chamber. The pressing part includes a sheet-shaped push plate, a connecting strip connected to the push plate at one end, a sliding plate that is laterally sealed and slidable in the sliding cavity, and a first spring. The sliding plate divides the sliding cavity into a first chamber communicating with the ventilation hole and a second chamber communicating with the air passage. The first spring is located in the first chamber and is in its normal state when the balloon does not contact the push plate. The second chamber... Relative to the first chamber located near the pusher, one end of the connecting strip slides laterally through the second chamber and connects to the slide plate. A limiting protrusion is provided on the inner wall of the sliding chamber to limit the slide plate from blocking the airway. When the balloon inflates, it gradually squeezes the pusher, causing the slide plate to increase the volume of the sealed second chamber and create a negative pressure. This creates a negative pressure in the airway connected to the second chamber, causing the airbag to contract. When the balloon contracts, the pusher loses pressure and resets under the rebound compression of the first spring. The first chamber contracts, and gas is pushed into the airway, causing the airbag to inflate again, thus achieving control over the state of the airbag.

[0011] Furthermore, the exercise grading mechanism also includes a reset part disposed on the housing for pressing all movable support plates into the storage groove when the suspension plate is located in the uppermost grading cavity, and the reset part does not interfere with the air cushion part, so that the training can be ended and the suspension plate reset when the patient's training effect reaches the highest standard, that is, when the suspension plate rises to the highest grading cavity.

[0012] Furthermore, the top and bottom of the housing are respectively formed with a first cavity and a second cavity. The reset part includes a first winding part disposed in the first cavity and a second winding part disposed in the second cavity. The first winding part includes a drive member installed in the first cavity and whose output shaft can rotate in both directions, and two sets of pull ropes with one end respectively wound in opposite directions around the output shaft of the drive member. The other ends of the two sets of pull ropes extend in opposite directions to the inner side walls on both sides of the training cavity where the first support part and the second support part are disposed, so that the two sets of pull ropes correspond to the first support part and the second support part respectively. The second winding part includes two rotating shafts respectively rotatably connected to the second cavity, two connecting belts with one end respectively wound around the two rotating shafts, two compression blocks located in the training cavity and respectively connected to the other ends of the two connecting belts extending in opposite directions, and two coil springs respectively disposed in the second cavity. Both rotating shafts are parallel to the output shaft of the drive unit. The two pressing blocks are respectively connected to two sets of pull ropes, and the distance between the two pressing blocks is greater than the diameter of the suspension plate, so that the two pressing blocks can pass through both sides of the suspension plate without affecting the suspension plate. The two coil springs are respectively coaxially arranged with the two rotating shafts, and the two ends of the two coil springs are respectively connected to the inner wall of the second cavity and the corresponding rotating shaft. When the coil spring is in the normal state, the pressing block is supported on the bottom wall of the training chamber so as not to hinder the use of the suspension plate. When it is necessary to reset the suspension plate, the drive unit is activated to retract the pull rope, which pulls the pressing block until the pressing block moves upward and the movable support plates are stored in the storage slot. At this time, the suspension plate is no longer supported by the movable support plates and resets to below the movable support plates. After the output shaft of the drive unit rotates in the opposite direction, the pressing block and the connecting belt are reset under the rebound action of the coil spring.

[0013] Furthermore, the extrusion block is provided with a guide ramp to facilitate passing from the side of the suspension plate.

[0014] Furthermore, the reset unit also includes a sensor disposed at the top of the training chamber. The sensor is electrically connected to the drive component. When the suspension plate is located in the topmost grading chamber and contacts the sensor, the drive component operates to reset the suspension plate, achieving fully automatic control reset without human intervention.

[0015] The pulmonary function rehabilitation trainer of the present invention has at least the following beneficial effects: it realizes pulmonary exhalation training through the cooperation between the balloon and the training tube; by setting up a support part to form multiple graded chambers, it realizes different standards of pulmonary exhalation training grades; and with the suspension board, it is convenient to intuitively understand the training standards and training status of the corresponding stage, ensuring that the patient can automatically match the appropriate training standards according to the appropriate situation when performing pulmonary training, so that the training results and training standards are automatically improved synchronously, thereby obtaining the best training effect.

Detailed Implementation

[0030] The invention will now be further described with reference to the accompanying drawings.

[0031] like Figures 1 to 7 As shown, the pulmonary function rehabilitation trainer of the present invention includes a shell 1 with a cylindrical training chamber 11 inside, a balloon 2 disposed in the training chamber 11, a training tube 3 disposed on the shell 1 and connected to the balloon 2 at one end, an air nozzle 4 disposed at the other end of the training tube 3, and an exercise grading mechanism 5 disposed in the training chamber 11. The shell 1 is used to protect the balloon 2 from being punctured due to its softness and fragility. The balloon 2, in conjunction with the training tube 3, allows the patient to inflate the balloon 2 by blowing air into the air nozzle 4, thereby conducting exhalation training to achieve the effect of exercising and rehabilitating pulmonary function. The exercise grading mechanism 5, in conjunction with the balloon 2, sets different levels of exhalation training, so that the patient receives different levels of training at different times, and the training level is adapted to the patient's training situation to achieve the purpose of progressive training, gradually increasing the training difficulty, thereby better conducting pulmonary function rehabilitation training. At the same time, it also allows for a more intuitive understanding of the patient's completion of the corresponding standards, making it easier for patients or medical staff to understand the patient's training progress more clearly.

[0032] like Figure 1 , Figure 2 and Figure 6As shown, in this embodiment, the housing 1 has a columnar structure, and the bottom of the housing 1 is a horizontal plane to support the entire housing 1 on the ground or other plane. The training cavity 11 is cylindrical and its axis is distributed vertically. An opening is opened on the side wall of the housing 1 to connect the training cavity 11 with the outside, and a transparent observation window 12 is installed at the opening. The length direction of the observation window 12 and the opening is arranged vertically so that the situation inside the training cavity 11 can be seen directly through the observation window 12. In order to facilitate the maintenance of the internal structure of the housing 1, a cover (not shown in the figure) is fastened to the housing 1 so that the structure inside the training cavity 11 can be maintained by opening the cover. A first cavity 13 is formed at the top of the housing 1, and a second cavity 14 is formed at the bottom of the housing 1. Both the first cavity 13 and the second cavity 14 are cylindrical and distributed in the horizontal direction. The circumferential directions of the first cavity 13 and the second cavity 14 are parallel to each other. The training cavity 11 is located between the first cavity 13 and the second cavity 14, so that the first cavity 13 is directly above the training cavity 11 and the second cavity 14 is directly below the training cavity 11. Inside the housing 1, in a horizontal direction perpendicular to the axial direction of the first cavity 13 (i.e., in the radial direction of the first cavity 13 in a horizontal position), on opposite sides of the first cavity 13, two first channels 15 are respectively opened. The two first channels 15 extend horizontally in the opposite direction from the first cavity 13 and then extend outward and downward in an arc until they penetrate the top wall of the training cavity 11 to connect the training cavity 11. The ends of the two first channels 15 that connect to the first cavity 13 are opened at different heights, and the openings of the two first channels 15 that connect to the training cavity 11 are flush with the inner sidewall of the training cavity 11. Inside the housing 1, two second channels 16 are respectively opened on opposite sides of the second cavity 14 in a horizontal direction perpendicular to the axial direction of the second cavity 14. The two second channels 16 extend horizontally in the opposite direction from the second cavity 14 and then extend outward and upward in an arc until the second channel 16 penetrates the bottom wall of the training cavity 11 to connect the training cavity 11. The ends of the two second channels 16 that connect to the second cavity 14 are opened at different heights. The openings of the two second channels 16 that connect to the training cavity 11 are flush with the inner sidewall of the training cavity 11. The two first channels 15 and the two second channels 16 are aligned in pairs in the vertical direction.

[0033] like Figure 2 and Figure 6 As shown, in this embodiment, the balloon 2 is made of latex or rubber and is generally elliptical. The bottom of the balloon 2 is connected to the inner wall of the training cavity 11 by a horizontally arranged connecting rod 17. This can be achieved by clamping the bottom of the balloon 2 onto the connecting rod 17 or by other fixing methods. Two connecting rods 17 are provided, located on opposite sides of the training cavity 11, both positioned away from the observation window 12. Both connecting rods 17 have vertically penetrating grooves.

[0034] like Figure 1, Figure 2 and Figure 5As shown in the illustration, in one embodiment, the training tube 3 includes an inlet tube 31 connected to and communicating with the bottom of the balloon 2, and an outlet tube 32. The other end of the inlet tube 31 extends out of the shell 1 and is connected to the mouthpiece 4. The patient blows air into the mouthpiece 4, which then blows through the inlet tube 31 into the inner cavity of the balloon 2, causing the balloon 2 to gradually inflate. This allows for observation of the patient's lung volume and training in inhalation. The outlet tube 32 is used when the patient completes one inhalation and exhalation cycle. At this point, the balloon 2 rebounds and contracts because no more air is being supplied, and the air inside the balloon 2 is pushed out through the outlet tube 32. In this embodiment, both the inlet tube 31 and the outlet tube 32 are flexible tubes, which can be plastic corrugated tubes or flexible tubes made of other plastic materials. A first through hole communicating with the training chamber 11 is provided laterally on one side of the housing 1 where the observation window 12 is located. One end of the air inlet pipe 31 passes through the first through hole and inserts into the bottom of the balloon 2. At the same time, the air inlet pipe 31 and the bottom of the balloon 2 are connected and fixed by a detachable connection structure, such as by tightening or using a clamp to press together, so that the air inlet pipe 31 and the balloon 2 can be detached for easy replacement of the balloon 2. The other end of the air inlet pipe 31 is located outside the housing 1 so that the patient can pull the air inlet pipe 31 for use. When a patient completes an exhalation and inhales, the air may return through the inlet tube 31 due to the rebound of the balloon 2. The inlet tube 31 exposed to the air and the residual exhaust gas in the balloon 2 may contain a large number of bacteria, dust and other substances. Inhaling these gases during the inhalation and ventilation process is detrimental to the respiratory health of patients whose lung function is recovering. To avoid this problem, a one-way valve 33 is installed inside the inlet tube 31 to direct the gas into the balloon 2, allowing the patient to exhale into the delivery tube. However, the exhaust gas delivered by the rebound of the balloon 2 cannot be reversed through the delivery tube, thus preventing the exhaust gas from being directly inhaled into the respiratory tract and lungs by the patient through the inlet tube 31 during ventilation, which would increase the burden on the lungs. A second through hole is provided on the shell 1 below the first through hole, which connects to the training chamber 11. One end of the air outlet pipe 32 passes through the second through hole and is connected to the end of the air inlet pipe 31 located inside the training chamber 11. The air outlet pipe 32 is located on the air inlet pipe 31 between the balloon 2 and the one-way valve 33 at the position where it connects to the air inlet pipe 31. The inner cavity of the air outlet pipe 32 is connected to the inner cavity of the air inlet pipe 31 so that the gas discharged from the balloon 2 can be discharged from the air outlet pipe 32. The other end of the air outlet pipe 32 extends to the outside of the shell 1.To prevent the patient from exhaling through the exhaust tube 32 during breathing, which would affect the effectiveness of lung exercises and the judgment of the balloon 2's inflation level, a manually pressable sealing plug 34 is installed at the end of the exhaust tube 32 connected to the intake tube 31. When the patient exhales into the intake tube 31, the sealing plug 34 blocks the exhaust tube 32 to prevent gas from entering, thus inflating the balloon 2. During the patient's breathing process, the balloon 2 rebounds and contracts, and the gas cannot pass through the one-way valve 33 and accumulates in the intake tube 31. The patient can manually press the sealing plug 34 to release the excess waste gas from the exhaust tube 32. The sealing plug 34 includes a funnel-shaped opening 341 disposed within the outlet pipe 32, a second spring 342 formed within the opening 341, a sealing plate 343 connected to one end of the second spring 342 for blocking the opening 341, and a push rod 344 connected to the sealing plate 343 and movably extending out of the outlet pipe 32. The opening 341 is located inside the end of the outlet pipe 32 near the outside of the housing 1. The end of the opening 341 closer to the inlet pipe 31 along the axial direction is the larger opening end, and the end of the opening 341 away from the inlet pipe 31 is the smaller opening end. 43 is installed on the small end of the pipe opening 341, and one end of the second spring 342 is connected to the sealing plate 343. There is a horizontal bar 344 on the large end of the pipe opening 341 along the radial direction of the large end of the pipe opening 341. The horizontal bar 344 does not block the large end of the pipe opening 341. The other end of the second spring 342 is connected to the horizontal bar 344. When the sealing plate 343 blocks the small end of the pipe opening 341, the second spring 342 is in the normal state and makes the sealing plate 343 block the pipe opening 341, preventing gas from easily leaking from the pipe opening 341 to the gas outlet pipe 32. The diameter of the occlusion plate 343 is smaller than the diameter of the larger end of the tube opening 341. When the patient does not exhale into the inlet tube 31, pressing the push rod 344 inward causes the occlusion plate 343 to open the smaller end of the tube opening 341. At this time, the second spring 342 is compressed, allowing gas to be output from the outlet tube 32 to ensure the next training session. After releasing the push rod 344, the second spring 342 compresses the occlusion plate 343 to block the tube opening 341 again. It should be noted that the tube opening 341 should be coaxial with the end of the outlet tube 32 extending outside the housing 1 to facilitate the arrangement and use of the push rod 344. In another embodiment, the training tube 3 only includes the inlet tube 31, one end of which passes through the first through hole to connect to the bottom of the balloon 2, and the other end of which is located outside the housing 1.

[0035] like Figure 1 As shown, in this embodiment, the mouthpiece 4 has a flat or elliptical trumpet-shaped structure. The mouthpiece 4 is connected to the air inlet pipe 31 at one end with a small opening and the mouthpiece 4 is used to contact the patient at the other end with a large opening. This allows the large opening of the mouthpiece 4 to form a seal with the patient's mouth skin to a certain extent when it contacts the patient's mouth, so that the gas only enters the air inlet pipe 31.

[0036] like Figures 2 to 6As shown, in this embodiment, the exercise grading mechanism 5 includes a suspension plate 51 located directly above and supported on the balloon 2, a support portion 52 disposed on the inner wall of the training chamber 11, an air cushion portion 53 disposed corresponding to the support portion 52 to prevent the suspension plate 51 from moving upward, a trigger control portion 54 for the air cushion portion 53 to contract when the balloon 2 inflates and is squeezed by the balloon 2, and a reset portion 55 disposed on the housing 1 for resetting the support portion 52 when the suspension plate 51 is at its highest position. The suspension plate 51 changes with the height of the bottom of the balloon 2; the suspension plate 51 rises when the balloon 2 inflates and falls when the balloon 2 rebounds and contracts, so that the patient's exhalation training results and corresponding degree can be judged by observing the height of the suspension plate 51 during training. The suspension plate 51, in conjunction with the support unit 52, allows the patient to more intuitively see the standard position of the suspension plate 51 and maintain the current standard of exhalation training within a certain period. It also allows the patient to visually see their training status and whether they have reached the standard during each training session, enabling them to adjust their state or rest in time. This ensures the patient maintains optimal training status and effect, avoiding overtraining or insufficient training intensity. The air cushion 53 prevents the suspension plate 51 from rising when the patient is not exhaling, preventing changes in the height of the suspension plate 51 due to abnormal situations such as the shell 1 tipping over, which could affect training. The trigger control unit 54 prevents the air cushion 53 from interfering with the rise of the suspension plate 51 during exhalation training. The entire process requires no manual control except when the patient is exhaling, achieving the desired effect.

[0037] like Figure 2 and Figure 6As shown in this embodiment, the suspension plate 51 is a circular sheet and is slidably disposed within the training cavity 11 in a vertical direction, so that the suspension plate 51 slides only relative to the training cavity 11 along the axial direction of the training cavity 11, allowing the suspension plate 51 to move up and down. The suspension plate 51 is made of lightweight plastic, such as polypropylene, which is inexpensive and lightweight. The thickness of the suspension plate 51 is set to within 2mm to ensure that the balloon 2 can support the suspension plate 51 when it inflates and to minimize the obstruction of the weight of the suspension plate 51 to the inflation of the balloon 2. In order to support the suspension plate 51 as stably as possible during the inflation of the balloon 2, the suspension plate 51 is convex upward from the center position, so that the suspension plate 51 is an upwardly convex arc surface and the bottom surface of the suspension plate 51 is an upwardly concave arc surface. In this way, the contact area is increased when the balloon 2 contacts the suspension plate 51, so that there is more contact surface between the balloon 2 and the suspension plate 51, the force distribution is more uniform, and the influence of the suspension plate 51 on the inflation of the balloon 2 is reduced to a certain extent. Two sliding rods 18 are arranged parallel to each other in the vertical direction and spaced apart in the training cavity 11. The two sliding rods 18 pass through the slots of the two connecting rods 17 respectively. The two sliding rods 18 are opposite to the center positions of the balloon 2 and the suspension plate 51 and are symmetrically distributed. Two third through holes are symmetrically opened on the suspension plate 51 along the same radial direction with the center as the axis. The suspension plate 51 is slidably sleeved on the sliding rods 18 through the two third through holes to slide vertically.

[0038] like Figure 2 , Figure 6 and Figure 7 As shown in this embodiment, the support 52 provides the training chamber 11 with multiple vertically distributed graded chambers 56. Each graded chamber 56 can support the suspension plate 51. During the inflation of the balloon 2, which causes the suspension plate 51 to rise, the suspension plate 51 moves upward relative to each graded chamber 56 and, driven by the balloon 2, is supported in graded chambers 56 at different heights according to the patient's expiratory volume. This allows the suspension plate 51 to move to the appropriate graded chamber 56 through the volume change caused by the inflation of the balloon 2, achieving automatic matching and replacement of the graded chambers 56. This facilitates the patient's clear understanding of their expiratory capacity and corresponding standard. The training is categorized into different levels. Each training session can be conducted according to the corresponding grade 56. The standard for each exhalation training session can be determined by whether the top of the balloon 2 touches the suspension plate 51. The extent to which the balloon 2 touches the suspension plate 51 and rises to the next grade 56 is considered as meeting the exhalation standard for that grade 56. Once the suspension plate 51 rises to the next grade 56, the patient can be considered to have reached a higher level of training standard. Subsequent training sessions can then focus on the corresponding intensity of breathing exercises in the grade 56. This allows for targeted training and enables the patient to understand their exhalation volume and training progress during the training.

[0039] In this embodiment, the support portion 52 includes a plurality of first support portions 52a and a plurality of second support portions 52b mirror-distributed on opposite inner sidewalls of the training cavity 11. That is, opposite support portions 52 can all be first support portions 52a, or all be second support portions 52b, or the first support portions 52a and the second support portions 52b can be opposite each other. In this embodiment, each first support portion 52a is disposed on the same side of the training cavity 11, and each second support portion 52b is disposed on the opposite side of the training cavity 11 from the first support portion 52a. Furthermore, each first support portion 52a and each second support portion 52b are equally spaced along the vertical direction. In this embodiment, each of the first support portion 52a and the second support portion 52b includes a storage groove 521 recessed in the inner wall of the training cavity 11 and a movable support piece 522 hinged to the bottom of the storage groove 521 and capable of being stored in the storage groove 521. The top of the movable support piece 522 swings inward and outward relative to the storage groove 521 so that the movable support piece 522 can be completely stored in the storage groove 521, or it can be tilted outward relative to the storage groove 521. The movable support piece 522 stored in the storage groove 521 will not hinder the movement of the suspension plate 51 and cannot support the suspension plate 51. Any two opposite movable support pieces 522 tilted outward relative to the storage groove 521 can be used to support the suspension plate 51, so that the suspension plate 51 is supported on the movable support piece 522 when the balloon 2 is not inflated. The space enclosed between any two adjacent movable support plates 522 of the first support portion 52a and the two adjacent movable support plates 522 of the second support portion 52b directly opposite it is defined as a graded cavity 56, and each graded cavity 56 represents a different training standard at a certain height.

[0040] During use, as balloon 2 inflates, the suspension plate 51 gradually moves from its position within the grading chamber 56 or its initial position towards the movable support plate 522 located above it, until the suspension plate 51 gradually presses upward against the movable support plate 522. The movable support plate 522 then gradually swings towards the receiving slot 521 until the suspension plate 51 is completely moved above the two movable support plates 522. After that, the suspension plate 51 enters the next grading chamber 56. When balloon 2 deflates, the suspension plate 51 rests on the two movable support plates 522 at the bottom of the grading chamber 56, allowing the patient to observe the grading chamber 56. When the patient performs the standard expiratory training, the balloon 2 touching the suspension plate 51 indicates that the standard has been met; otherwise, the standard has not been met. This allows for quick and easy assessment of the training progress.

[0041] In this embodiment, since the bottom of the movable support piece 522 is hinged to the bottom of the storage groove 521, the swing angle of the movable support piece 522 is relatively large. When the movable support piece 522 is tilted downwards, although it can still be squeezed back into the storage groove 521 under the pressure of the suspension plate 51, during the process of the balloon 2 expanding and not contacting the suspension plate 51, the downward tilted movable support piece 522 may cause the direction of the force when the balloon 2 expands and squeezes the movable support piece 522 to change or even be in the lateral direction. This will cause the movable support piece 522 to be stuck by the balloon 2 and affect the expansion of the balloon 2. Therefore, a base 5221 is formed on the bottom of the movable support plate 522 and on the side near the training cavity 11. When the movable support plate 522 is tilted outward toward the storage groove 521, the base 5221 is supported on the bottom wall of the storage groove 521. The angle between the side of the base 5221 facing the bottom wall of the storage groove 521 and the side of the movable support plate facing outward is an acute angle. When the movable support plate 522 is tilted outward and the base 5221 abuts against the bottom wall of the storage groove 521, the angle between the movable support plate 522 and the side of the storage groove 521 facing the training cavity 11 is an acute angle, so that the movable support plate 522 is tilted outward and upward relative to the storage groove 521, so that when the suspension plate 51 and the balloon 2 squeeze the movable support plate 522, only the side of the movable support plate 522 facing outward (i.e. the side facing away from the storage groove 521) is in contact, causing the movable support plate 522 to swing inward toward the storage groove 521. It should be noted that the distance between any two inclined movable support plates 522 is less than the diameter of the suspension plate 51, so that the suspension plate 51 can compress the movable support plates 522 during the ascent and can be supported by the movable support plates 522 after the balloon 2 retracts. It should be noted that the presence of the base 5221 makes the center of gravity on the outward-facing side of the movable support plate 522 greater than the center of gravity on the side facing the storage groove 521. Therefore, after each movable support plate 522 is compressed into the storage groove 521, the movable support plate 522 will swing outward on its own after the force applied to it is removed; a third spring can also be provided on the side of the movable support plate 522 facing the storage groove 521 to ensure that the movable support plate 522 can automatically rotate out of the storage groove 521 after the force is removed.

[0042] like Figure 2 , Figure 6 and Figure 7As shown in this embodiment, the number of air cushions 53 corresponding to the number of grading chambers 56 is set to multiple, with each air cushion 53 disposed in each grading chamber 56 so that each grading chamber 56 has one air cushion 53. This is to block the suspension plate 51 when it is located in any grading chamber 56, preventing the suspension plate 51 from becoming disordered due to tilting. In this embodiment, disordered level refers to the suspension plate 51 sliding out of its corresponding grading chamber 56 and into another grading chamber 56 due to external factors such as accidental tilting or inversion of the trainer. In this embodiment, each air cushion 53 includes at least three airbags 531 evenly distributed along the circumferential direction of the inner wall of the training chamber 11. An air passage 532 for connecting each airbag 531 is formed in the side wall of the housing 1. The air passage 532 can be connected in series, in parallel, or in any other irregular manner to achieve the connection of each airbag 531. The trigger control unit 54 connects the air passage 532. Before use, the patient does not blow air into the air inlet tube 31. At this time, the balloon 2 is in a contracted state, and the air bag 531 is in an inflated state. When the patient blows air into the air inlet tube 31, causing the balloon 2 to inflate, the balloon 2 gradually squeezes the trigger control unit 54 during the inflating process. The trigger control unit 54 creates negative pressure in the airway 532, causing the air bag 531 to contract. At this time, it will not affect the coordination between the balloon 2 and the suspension plate 51. When the patient breathes or stops training, the balloon 2 contracts and moves away from the trigger control unit 54. The trigger control unit 54 pressurizes the airway 532 to restore the air bag 531 to an inflated state. At this time, the suspension plate 51 cannot pass through the air bag 531 and will malfunction. It should be noted that each airbag 531 does not interfere with the slide bar 18, movable support plate 522, storage slot 521, trigger control unit 54, and reset unit 55. The width of each airbag 531 in the horizontal direction is greater than the distance between the suspension plate 51 and the inner wall of the training chamber 11, so that each airbag 531 in any graded chamber 56 can block the suspension plate 51 when the airbag 531 is inflated, so that the suspension plate 51 cannot pass through. When each airbag 531 is in the contracted state, the suspension plate 51 can move vertically.

[0043] like Figure 2 and Figure 3As shown in this embodiment, the trigger control unit 54 includes a fixing block 541 fixedly connected to the inner wall of the training chamber 11 and a pressing part 542. A sliding cavity 543 is formed between the fixing block 541 and the inner wall of the training chamber 11 of the housing 1. A ventilation hole 544 is formed on the side of the sliding cavity 543 away from the training chamber 1, which passes through the housing 1 to connect the sliding cavity 543 and the outside of the housing 1. The pressing part 542 is located inside the training chamber 11 and one end is located outside the sliding cavity 543. The other end of the pressing part 542 is sealed and slidably connected inside the sliding cavity 543. By expanding or retracting the balloon 2, the balloon 2 squeezes or releases the pressing part 542, thereby controlling the change of air pressure in the sliding cavity 543, thereby controlling the change of air pressure in the airway 532. In this embodiment, the pressing part 542 includes a sheet-shaped push plate 5421, a connecting strip 5422 connected to the push plate 5421 at one end, a sliding plate 5423 that is slidably disposed in the sliding cavity 543 in the lateral direction, and a first spring 5424 disposed in the sliding cavity 543. The expansion of the balloon 2 is used to squeeze or release the push plate 5421, thereby driving the connecting strip 5422 and the sliding plate 5423 to move laterally along the sliding cavity 543, and the first spring 5424 is contracted or extended by the influence of the sliding plate 5423. In this embodiment, the sliding plate 5423 divides the sliding cavity 543 into a first chamber 5431 communicating with the ventilation hole 544 and a second chamber 5432 communicating with the air passage 532. The first spring 5424 is located in the first chamber 5431 and is in normal condition when the balloon 2 is not in contact with the push plate 5421. The two ends of the first spring 5424 are respectively connected to the inner wall of the first chamber 5431 away from the second chamber 5432 and the sliding plate 5423. Alternatively, the first spring 5424 can be placed directly in the first cavity 13 without affecting its function. The second chamber 5432 is relative to the first chamber 5431. Located near the push plate 5421, a fourth through hole is provided on the fixing block 541 along the sliding direction of the slide plate 5423. One end of the connecting strip 5422 is sealed and slides through the fourth through hole to enter the second chamber 5432. The end of the connecting strip 5422 that enters the second chamber 5432 is connected to the slide plate 5423. To ensure the seal between the connecting strip 5422 and the second chamber 5432, a sealing gasket 545 can be provided in the second chamber 5432 to maintain the air pressure in the second chamber 5432 from being leaked through the fourth through hole while ensuring the sliding passage between the connecting strip 5422 and the fourth through hole. In this embodiment, the sliding cavity 543 is cylindrical with a smooth inner wall surface and a hard inner wall material. The slide plate 5423 is a piston, which can be compared with the structure of the syringe barrel and piston to make the slide plate 5423 and the sliding cavity 543 have a sealed sliding connection. The airway 532, at one end away from each airbag 531, merges into a channel and extends into the fixing block 541 to connect to the second cavity 14. The opening of the airway 532 connected to the second cavity 14 is close to the side of the second cavity 14 away from the first cavity 13.To prevent the slide plate 5423 from being close to the side of the second chamber 5432 away from the first chamber 5431, which could cause gas in the air passage 532 to leak into the first chamber 13, a limiting protrusion can be provided on the inner wall of the sliding cavity 543 to limit the slide plate 5423 from blocking the air passage 532, so that the slide plate 5423 cannot block or pass through the opening of the air passage 532 towards the push plate 5421, thereby preventing the air passage 532 from connecting to the first chamber 5431.

[0044] When balloon 2 inflates to squeeze push plate 5421, push plate 5421 slides toward the first chamber 5431, causing the first chamber 5431 to shrink. The corresponding volume of the second chamber 5432 increases. For the sealed second chamber 5432 and airway 532, the increase in volume of the second chamber 5432 creates negative pressure in the airway 532. The negative pressure causes each airbag 531 to contract. At this time, the first spring 5424 is squeezed by the slide plate 5423 and is compressed. When balloon 2 contracts, the first spring 5424 can rebound and extend to squeeze slide plate 5423. Slide plate 5423 causes push plate 5421 to move toward training chamber 11. The second chamber 5432 is compressed, causing each airbag 531 to inflate and expand, so as to block the suspension plate 51.

[0045] like Figure 2 , Figure 4 and Figure 6 As shown in this embodiment, the reset unit 55 is disposed on the housing 1 and is used to activate when the suspension plate 51 is located in the uppermost grading cavity 56, pressing all the movable support pieces 522 into the storage groove 521, so that the suspension plate 51 can descend and reset to an initial position after each movable support piece 522 is retracted into the storage groove 521. It should be noted that the initial position described in this embodiment is below each grading cavity 56, that is, the position where the suspension plate 51 is not in the grading cavity 56. At the same time, the suspension plate 51 in the initial position is supported by the connecting rod 17. In this embodiment, the reset unit 55 includes a first winding part 551 disposed in the first cavity 13, a second winding part 552 disposed in the second cavity 14, and a sensor 553 disposed at the top of the training cavity 11. The first winding part 551 is used to pull the second winding part 552 so that the second winding part 552 moves upward to reset each movable support piece 522. The sensor 553 is used to detect whether the suspension plate 51 has moved to the top of the training cavity 11.

[0046] In this embodiment, the first winding section 551 includes a drive member 5511 installed inside the first cavity 13 and whose output shaft can rotate in both directions, and two sets of pull ropes 5512 with one end respectively wound in opposite directions around the output shaft of the drive member 5511. The output shaft of the drive member 5511 is coaxially arranged along the axial direction of the first cavity 13. The drive member 5511 can be a low-speed motor capable of rotating in both directions, or it can be a cylinder capable of rotating in both directions. The drive member 5511 is fixedly installed inside the first cavity 13. A first sleeve 5513 can be coaxially arranged on the output shaft of the drive member 5511. The first sleeve 5513 is cylindrical and has two sets of annular grooves 55131 on its outer wall. Each set of annular grooves 55131 has two annular grooves 55131, and each annular groove 55131 is formed in a ring-shaped recess along the circumference of the first sleeve 5513. The annular grooves 55131 do not interfere with each other and are spaced apart. It should be noted that the first sleeve 5513 may not be required, and the pull rope 5512 may be directly wound around the output shaft. Two sets of pull ropes 5512 are designated as the first set and the second set, each consisting of two ropes. One end of each of the two pull ropes 5512 in the first set is connected to and wound around the two annular grooves 55131 of one set. One end of each of the two pull ropes 5512 in the second set is connected to the two annular grooves 55131 of the other set and wound around the annular grooves 55131 in the opposite direction to the pull ropes 5512 in the first set. The other ends of the two sets of pull ropes 5512 extend in opposite directions from opposite sides of the first sleeve 5513. Four first channels 15 are provided, two of which correspond to the two pull ropes 5512 in the first set, and the other two first channels 15 correspond to the two pull ropes 5512 in the second set. The other ends of the two sets of pull ropes 5512 continue to extend along the first channel 15 into the training cavity 11 and make contact with the inner wall of the training cavity 11 where the storage groove 521 is located. The two pull ropes 5512 in each set are located on both sides of the storage groove 521 so as not to interfere with the movable support plate 522.

[0047] In this embodiment, the second winding section 552 includes two rotating shafts 5521 rotatably connected to the second chamber 5432, two connecting straps 5522 with one end wound around the two rotating shafts 5521, two pressing blocks 5523 located in the training chamber 11 and connected to the other ends of the two connecting straps 5522 extending in opposite directions, and two coil springs 5524 respectively disposed in the second cavity 14. The two rotating shafts 5521 are parallel to and spaced apart along the axial direction of the second cavity 14, parallel to the output shaft of the drive member 5511. Two bearings are spaced apart vertically on the inner walls at both ends of the second cavity 14, and the two ends of the two rotating shafts 5521 are respectively connected to the inner ring of each bearing to achieve free rotation. One end of one connecting strap 5522 is connected to the outer wall of one of the rotating shafts 5521 and wrapped around the shaft 5521; one end of the other connecting strap 5522 is connected to the outer wall of the other rotating shaft 5521 and wrapped around the shaft 5521. The other ends of the two connecting straps 5522 extend in opposite directions. The second channels 16 are respectively aligned with the opposite ends of the two connecting straps 5522, so that the two connecting straps 5522 can move through the two second channels 16 and enter the training cavity 11 to connect to the two compression blocks 5523 respectively. In order to ensure that the compression blocks 5523 do not affect the use of the suspension plate 51, the openings of the two second channels 16 connecting to the training cavity 11 are respectively flush with the two sides of the storage slot 521 in the training cavity 11. The two compression blocks 5523 are respectively connected to two sets of pull ropes 5512, and the distance between the two compression blocks 5523 is greater than the diameter of the suspension plate 51, so that the two compression blocks 5523 will not affect the use of the suspension plate 51 when moving in the vertical direction. Two coil springs 5524 are coaxially arranged with two rotating shafts 5521, and the two ends of each coil spring 5524 are respectively connected to the inner wall of the second cavity 14 and the corresponding rotating shaft 5521. Preferably, in order to avoid the possibility that the extrusion block 5523 may not move straight in the vertical direction when passing the balloon 2 and the suspension plate 51, a guide slope is provided on the side of the extrusion block 5523 facing the balloon 2. The top of the guide slope is located at the top of the side of the extrusion block 5523 facing the storage groove 521, so that the entire extrusion block 5523 is arranged to gradually widen from top to bottom, so that the extrusion block 5523 can pass smoothly when it contacts the suspension plate 51 and the balloon 2.

[0048] When the coil spring 5524 is in normal condition, the compression block 5523 is supported on the bottom wall of the training chamber, and the suspension plate 51 can be used normally. When the suspension plate 51 moves to the top of the highest grading chamber 56 and approaches the sensor 553, the sensor 553 sends a signal to a controller. The controller controls the drive unit 5511 to run and wind up the pull rope 5512. The pull rope 5512 pulls the connecting belt 5522 out of the second chamber 14 by pulling the compression block 5523. During the pulling process, the rotating shaft 5521 rotates in the forward direction and the pull rope 5512 is wound into the first sleeve 5513 until the compression block 5523 and the connecting belt 5522 are completely squeezed upward and block the movable support plate 522. At this time, the coil springs 5524 are all in a coiled and compressed state, and the movable support plates 522 are all in their respective storage slots 521. At this time, the balloon 2 has usually been contracted, and the suspension plate 51 falls to the initial position under the guidance of the slide rod 18. Then the drive component 5511 reverses, and the coil springs 5524 rebound, causing the rotating shaft 5521 to rotate in the opposite direction to coil the connecting belt 5522, so that the pull rope 5512 is always taut and will not get tangled on the movable support plates 522 and other components. When the compression block 5523 contacts the bottom wall of the training chamber 11 again, each movable support plate 522 rotates back to the outside of the storage slot 521 to facilitate the next exhalation training.

[0049] In this embodiment, the sensor 553 can be a proximity switch, a light sensor 553, or other sensors 553. The controller is mounted on the housing 1. The housing 1 is equipped with a power supply. The power supply is electrically connected to the drive unit 5511, the sensor 553, and the controller. The controller is electrically connected to the drive unit 5511 and the sensor 553.

[0050] The working method of one embodiment of the pulmonary function rehabilitation trainer of the present invention is as follows: First, the suspension plate 51 is determined to be in the initial position. After the power is turned on to enable the sensor 553 and the controller to operate, the patient exhales into the mouthpiece 4. The exhaled air enters the balloon 2 through the air inlet tube 31, causing the balloon 2 to inflate. The inflated balloon 2 gradually lifts the suspension plate 51 upward. The lowest grading chamber 56 is usually relatively simple and easy. Therefore, during the first training session, the patient's exhaled air can usually move the suspension plate 51 upward and squeeze the two lowest movable support plates 522 until it moves into the lowest grading chamber 56. After that, ventilation can be performed. During the ventilation process, after manually pressing the push rod 344 to open the tube opening 341 of the sealing plug 343, the balloon 2 contracts and exhausts air into the air inlet tube 31. The patient can then repeat the process in the same grading chamber 56. The training is repeated multiple times until the suspension plate 51 continues to rise into the next level cavity 56, gradually increasing the training difficulty and making the training progressively stronger. When the suspension plate 51 rises above the two movable support plates 522 above the highest level cavity and approaches the sensor 553, the sensor 553 sends a signal to the controller. The controller controls the drive unit 5511 to run the winding pull rope 5512. The pull rope 5512 pulls the squeezing block 5523 to move upward to retract each movable support plate 522 into the storage groove 521, causing the suspension plate 51 to fall back to the initial position. When the suspension plate 51 is in place, the controller controls the drive unit 5511 to run in the opposite direction. The coil spring 5524 is no longer pulled, causing the rotating shaft 5521 to rotate to wind up the connecting belt 5522, thereby taut and pulling the pull rope 5512 until the connecting belt 5522 returns to its original position.
