Description

Technical Field

[0001] This invention relates to the field of clinical exercise technology in traditional Chinese medicine cardiovascular medicine, specifically to a breathing exercise device for traditional Chinese medicine cardiovascular medicine. Background Technology

[0002] Cardiovascular diseases, including insufficient blood supply to the heart, arrhythmia, myocardial hypertrophy, and other cardiovascular diseases, can all affect the function of the cardiovascular system. Cardiovascular diseases are more common in middle-aged and elderly people and are closely related to their lifestyle and exercise habits. Since cardiovascular diseases are closely related to the heart, strengthening exercise, improving physical fitness, and enhancing immunity become particularly important. Compared to different types of exercise, aerobic exercise can greatly improve the aggravation of cardiovascular diseases, promote blood circulation, and the intensity of aerobic exercise is relatively moderate, making it easier for patients to adapt.

[0003] In the rehabilitation training of cardiovascular medicine practitioners, Tai Chi and Baduanjin exercises are often used to improve cardiovascular diseases. However, these rehabilitation training exercises cannot target respiratory resistance, which can effectively improve cardiovascular function, lower blood pressure, increase respiratory muscle strength, and promote cardiac rehabilitation.

[0004] Therefore, there is an urgent need for a clinical breathing exercise device for cardiovascular medicine in traditional Chinese medicine to solve the problem that cardiovascular disease patients cannot effectively perform breathing resistance training. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a clinical breathing exercise device for cardiovascular medicine in traditional Chinese medicine, thereby solving the problem that cardiovascular disease patients cannot effectively perform breathing resistance training.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A clinical breathing exercise device for cardiovascular medicine in traditional Chinese medicine is characterized by comprising a docking cover, an assembly base, and an adjustment mechanism. The docking cover is fixedly installed at the front end of the assembly base and is used to seal and fit over the patient's face. An air inlet is provided at the rear end of the assembly base, and a sliding cavity communicating with the air inlet is provided inside the assembly base. A nasal inlet is provided at the front end of the assembly base to connect the docking cover and the sliding cavity. The adjustment mechanism comprises a lifting structure and an elastic airbag. The lifting structure is slidably disposed in the sliding cavity, and an elastic airbag is provided at the end of the lifting structure located in the sliding cavity. The elastic airbag is used to seal the connection between the sliding cavity and the air inlet, and provides a gap for communication between the sliding cavity and the air inlet after deformation under pressure. The lifting structure is used to compress and control the tightness of the elastic airbag sealing the connection between the sliding cavity and the air inlet.

[0007] To optimize the above technical solution, the specific measures also include: Furthermore, the lifting structure includes a threaded column and a locking unit. The threaded column is slidably installed inside the slide cavity. An elastic airbag is fixedly installed at the upper end of the threaded column in the slide cavity. The upper part of the threaded column has a threaded groove on its outer wall. The lower part of the threaded column is a smooth rod structure and slides out from the bottom of the slide cavity to the outside of the mounting base. The locking unit is used to engage with the threaded groove of the threaded column.

[0008] Furthermore, it also includes a first return spring. The diameter of the lower part of the threaded column is smaller than that of the upper part. A first return spring is installed between the lower end of the upper part of the threaded column and the bottom end of the sliding cavity. The upper end of the first return spring is rotatably connected to the lower end of the upper part of the threaded column. The first return spring provides a downward pulling force to the threaded column. The locking unit can be engaged in the threaded groove of the threaded column or away from the threaded groove of the threaded column.

[0009] Furthermore, the locking unit includes a threaded pin, a third return spring, and a release mechanism. The mounting base also has a sliding groove communicating with the interior of a sliding cavity. A threaded pin is slidably installed within the groove. One end of the threaded pin near the sliding cavity has a top pin for engaging with the threaded groove of the threaded post. A magnetic block is fixedly installed at the other end of the threaded pin. A limiting flange surrounding the threaded pin is fixedly installed inside the groove. The threaded pin slides at the center of the annular limiting flange, and a third return spring is fixedly installed between the limiting flange and the top pin. The third return spring provides a force that presses the threaded pin against the threaded post. The release mechanism provides a magnetic force to the magnetic block, moving it away from the threaded post.

[0010] Furthermore, the assembly base also has an assembly cavity for connecting the sliding cavity and the nasal suction hole. The release mechanism includes an assembly column fixedly installed inside the assembly cavity. A sliding rod is slidably installed inside the assembly column. The lower end of the sliding rod passes through the bottom end of the assembly column and extends out of the assembly base. A magnetic flange is fixedly installed on the outer wall of the sliding rod inside the assembly column. A second return spring is fixedly installed between the magnetic flange and the bottom end of the assembly column. The second return spring is used to provide downward pulling force for the sliding rod. The two ends of the slide groove are respectively connected to the interior of the sliding cavity and the assembly column. The magnetic flange is used to magnetically attract the magnetic block when the second return spring drives the sliding rod to move downward.

[0011] Furthermore, a clamping unit is fixedly installed on the top of the sliding rod, and the upper end of the assembly column has a tapered design that is wider at the top and narrower at the bottom. The clamping unit includes a locking post, a pull rod, and a limiting post fixedly installed on the top of the sliding rod. Multiple limiting balls are arranged in an array around the outer wall of the locking post and slidably installed. The upper end of the assembly column is connected to the limiting post through the pull rod. The limiting post can be inserted from the upper end of the locking post and abut against the multiple limiting balls to make it move outward. The limiting balls are used to engage at the narrow opening at the upper end of the tapered shape.

[0012] Furthermore, the assembly base has an intermediate channel inside, with its two ends communicating with the assembly cavity and the nasal suction hole, respectively. The assembly base also has a sliding tube inside, which communicates with the nasal suction hole and the top of the assembly column, respectively. The top of the assembly column is provided with a flexible membrane, and the lower end of the flexible membrane is used to connect a pull rod. The flexible membrane isolates the communication between the sliding tube and the interior of the assembly column. The sliding tube is provided with a trigger unit, which includes a sliding block. The sliding block is slidably and sealingly disposed in the sliding tube.

[0013] Furthermore, a limiting ring is fixedly installed inside the slide tube, the center of the limiting ring is a through hole, and a groove communicating with the slide tube is opened on the side of the limiting ring near the assembly column inside the slide tube. The sliding block is slidably sealed in the slide tube between the limiting ring and the assembly column.

[0014] Furthermore, the outer wall of the mounting base is provided with an elastic rubber cord for fitting over the patient's head.

[0015] Furthermore, there may be two nasal suction holes.

[0016] The beneficial effects of this invention are: This invention, through the design of a docking cover, mounting base, and adjustment mechanism, allows for the adjustment of the lifting structure and elastic airbag as needed after the docking cover is fitted over the patient's mouth and nose. The lifting structure adjusts the intensity of the compression of the elastic airbag, thereby adjusting the tightness of the connection between the elastic airbag and the air inlet. This allows the resistance to oxygen entering the sliding cavity through the air inlet to be adjusted as needed, enabling patients to perform respiratory resistance training of different intensities as required. This addresses the problem of cardiovascular disease patients being unable to effectively perform respiratory resistance training and meets their own training intensity needs, thereby improving the patient's rehabilitation efficiency.

[0017] This invention allows for adjustment of the resistance to oxygen entering the assembly cavity through the air inlet by rotating the threaded column, thereby enabling patients to undergo different levels of respiratory resistance training, which can improve cardiovascular function, lower blood pressure, enhance respiratory muscle strength, and promote cardiac rehabilitation. When a patient experiences a special condition, they may be unable to inhale oxygen from the air inlet into the assembly cavity, triggering the release mechanism to immediately stop the patient's respiratory resistance training, thus ensuring the patient's safety during respiratory resistance training.

[0020] The invention will now be described in further detail with reference to the accompanying drawings.

[0021] As attached Figure 1 Appendix Figure 2 and attached Figure 3As shown in the figure, a clinical respiratory training device for cardiovascular medicine in traditional Chinese medicine according to an embodiment of the present invention includes a docking cover 1, an assembly base 2, and an adjustment mechanism. The docking cover 1 is fixedly installed at the front end of the assembly base 2 and is used to seal the patient's face. An air inlet 25 is provided at the rear end of the assembly base 2. A sliding cavity communicating with the air inlet 25 is provided inside the assembly base 2. A nasal inlet 24 communicating with the docking cover 1 and the sliding cavity is provided at the front end of the assembly base 2. The adjustment mechanism includes a lifting structure and an elastic airbag 5. The lifting structure is slidably disposed in the sliding cavity. The end of the lifting structure located in the sliding cavity is provided with an elastic airbag 5. The elastic airbag 5 is used to seal the connection between the sliding cavity and the air inlet 25, and provides a gap for communication between the sliding cavity and the air inlet 25 after deformation under pressure changes. The lifting structure is used to squeeze and control the tightness of the elastic airbag 5 sealing the connection between the sliding cavity and the air inlet 25.

[0022] This invention, through the arrangement of the docking cover 1, the mounting base 2, and the adjustment mechanism, allows for the adjustment of the lifting structure and the elastic airbag 5 as needed after the docking cover 1 is fitted over the patient's mouth and nose. The lifting structure adjusts the intensity of the compression of the elastic airbag 5, thereby adjusting the tightness of the connection between the elastic airbag 5 and the air inlet 25. This allows the resistance when oxygen enters the sliding cavity through the air inlet 25 to be adjusted and changed as needed. This enables patients to perform respiratory resistance training of different intensities as needed, solving the problem that cardiovascular disease patients cannot effectively perform respiratory resistance training and meeting their own training intensity requirements, thereby improving the patient's rehabilitation efficiency.

[0023] In this embodiment, the adjustment mechanism can change the resistance when oxygen enters the assembly base 2 through the air inlet 25, thereby adjusting the intensity of breathing exercises as needed. In this embodiment, the airbag 5 can be made of TPV material.

[0024] In another specific embodiment, the lifting structure includes a threaded column 3 and a locking unit. The threaded column 3 is slidably installed inside the sliding cavity. An elastic airbag 5 is fixedly installed at the upper end of the threaded column 3 in the sliding cavity. The upper part of the threaded column 3 has a threaded groove on its outer wall, and the lower part of the threaded column 3 is a smooth rod structure that slides out from the bottom of the sliding cavity to the outside of the mounting base 2. The locking unit is used to engage with the threaded groove of the threaded column 3. Thus, during use, the threaded column 3 can be locked in its operating state by engaging with the threaded groove of the threaded column 3 through the locking unit; at the same time, the threaded column 3 can be rotated to adjust its rotation and rise or fall according to the position engaged by the locking unit, thereby achieving a high degree of precision adjustment of the compression strength of the elastic airbag 5 by the lifting structure.

[0025] In a further embodiment, a first return spring 4 is also included. The diameter of the lower part of the threaded column 3 is smaller than that of the upper part. The first return spring 4 is installed between the lower end of the upper part of the threaded column 3 and the bottom end of the sliding cavity. The upper end of the first return spring 4 is rotatably connected to the lower end of the upper part of the threaded column 3. The first return spring 4 provides a downward pulling force to the threaded column 3. The locking unit can be engaged in or away from the threaded groove of the threaded column 3. Thus, during use, the locking unit can be engaged in or away from the threaded groove of the threaded column 3 as needed. When the locking unit is engaged in the threaded groove of the threaded column 3, the threaded column 3 performs normal adjustment and limiting functions. When the locking unit is away from the threaded groove of the threaded column 3, the locking unit no longer restricts the movement of the threaded column 3. Under the action of the first return spring 4, the threaded column 3 drives the elastic airbag 5 to move downward quickly to connect the sliding cavity with the air inlet 25. Therefore, in the event of a dangerous situation where the patient cannot breathe normally during training, the restrictive device can be quickly released, and oxygen can be provided normally.

[0026] As attached Figure 5 As shown, in a further embodiment, the locking unit includes a threaded pin 17, a third return spring 18, and a release mechanism. The mounting base 2 also has a sliding groove inside, which communicates with the interior of the sliding cavity. The threaded pin 17 is slidably installed in the sliding groove. One end of the threaded pin 17 near the sliding cavity is provided with a top pin 26, which is used to engage with the threaded groove of the threaded post 3. The other end of the threaded pin 17 is fixedly installed with a magnetic block 20. A limiting flange 19 surrounding the threaded pin 17 is fixedly installed inside the sliding groove. The threaded pin 17 slides at the center of the annular limiting flange 19, and a third return spring 18 is fixedly installed between the limiting flange 19 and the top pin 26. The third return spring 18 is used to provide the force for the threaded pin 17 to press against the threaded post 3 and is coaxial with the threaded pin 17. The release mechanism is used to provide a magnetic attraction force to the magnetic block 20 away from the threaded post 3. In use, the release mechanism provides a magnetic force to the magnetic block 20 away from the threaded post 3, which can be easily controlled to release the threaded nail 17 from the threaded post 3. As a result, the threaded post 3 slides down under the action of the first return spring 4 until the elastic air bag 5 is no longer blocked at the connection between the slide cavity and the air inlet 25, and the air inlet 25 can deliver oxygen to the interior of the mounting base 2.

[0027] In a further embodiment, the assembly base 2 is further provided with an assembly cavity 6 for connecting the sliding cavity and the nasal suction hole 24. The release mechanism includes an assembly column 7 fixedly installed inside the assembly cavity 6. A sliding rod 8 is slidably installed inside the assembly column 7. The lower end of the sliding rod 8 passes through the bottom end of the assembly column 7 and extends out of the assembly base 2. A magnetic flange 11 is fixedly installed on the outer wall of the sliding rod 8 inside the assembly column 7. A second return spring 9 is fixedly installed between the magnetic flange 11 and the bottom end of the assembly column 7. The second return spring 9 is used to provide downward pulling force for the sliding rod 8 and is coaxial with the sliding rod 8. The two ends of the slide groove are respectively connected to the interior of the sliding cavity and the assembly column 7. The magnetic flange 11 is used to magnetically attract the magnetic block 20 when the second return spring 9 drives the sliding rod 8 to move downward. Therefore, during use, the sliding rod 8 can be manually pressed against the end of the mounting post 7 as needed to restrict the movement of the sliding rod 8, thus enabling normal use of the device. In case of an emergency, the restriction on the sliding rod 8 can be released, and the sliding rod 8 can move downward under the drive of the second return spring 9 until the magnetic flange 11 on the sliding rod 8 is flush with the magnetic block 20. The magnetic flange 11 can provide sufficient magnetic force to the magnetic block 20, causing it to move the threaded pin 17 away from the threaded post 3 and release the lock on the threaded post 3.

[0028] As attached Figure 4 As shown, in a further embodiment, a locking unit is fixedly installed on the top of the sliding rod 8. The locking unit prevents the sliding rod 8 from moving downwards. The upper end of the assembly column 7 has a tapered design that is wider at the top and narrower at the bottom. The locking unit includes a locking post 27, a pull rod 13, and a limiting post 16 fixedly installed on the top of the sliding rod 8. Multiple limiting balls 12 are arranged in an array around the outer wall of the locking post 27 and slidably installed. The upper end of the assembly column 7 is connected to the limiting post 16 through the pull rod 13. The limiting post 16 can be inserted from the upper end of the locking post 27 and abut against the multiple limiting balls 12, causing it to move outwards. The limiting balls 12 are used to engage at the narrow opening at the upper end of the tapered shape. Thus, during use, the locking unit can automatically lock the upper end of the sliding rod 8, facilitating normal use. If necessary, the sliding rod 8 can be manually pulled to separate it from the locking unit, and then quickly moved downwards under the drive of the second return spring 9 to further unlock it. After use, simply push the sliding rod 8 back to the upper locking post 27 and the limiting post 16 to re-engage and lock them in place. In this embodiment, the side wall of the limiting post 16 may be provided with a groove for engaging the limiting ball 12 to ensure stability during engagement. The limiting post 16 may also adopt a deformable elastic structure to further ensure stability during engagement.

[0029] In a further embodiment, the assembly base 2 has an intermediate channel 10 inside, with both ends of the intermediate channel 10 communicating with the assembly cavity 6 and the nasal suction hole 24, respectively. The assembly base 2 also has a sliding tube 15 inside, which communicates with the nasal suction hole 24 and the top of the assembly column 7, respectively. The top of the assembly column 7 is provided with a flexible membrane 14, and the lower end of the flexible membrane 14 is used to connect the pull rod 13. The flexible membrane 14 isolates the communication between the sliding tube 15 and the interior of the assembly column 7. The sliding tube 15 is provided with a triggering unit, which includes a sliding block 21. The sliding block 21 is slidably and sealingly disposed in the sliding tube 15. Therefore, under normal circumstances, during use, the sliding block 21 blocks the sliding tube 15, and the sliding tube 15 does not participate in the oxygen transfer. Oxygen passes through the inlet 25 sequentially through the sliding cavity, the assembly cavity 6, the intermediate channel 10, and the nasal inhalation port 24 for normal training. When oxygen cannot enter normally from the sliding cavity to supply training, the oxygen in the assembly cavity 6, the intermediate channel 10, and the docking cover 1 is consumed. At the same time, breathing causes pressure changes. Due to the pressure change, the sliding block 21 moves towards the nasal inhalation port 24 in the sliding tube 15, thereby indirectly changing the pressure above the flexible membrane 14, causing the flexible membrane 14 to bulge. The bulging flexible membrane 14 pulls the pull rod 13 and the limiting post 16 upward and separates from the locking post 27 at the top of the sliding rod 8. The sliding rod 8 then performs a subsequent downward movement to automatically unlock. After use, the flexible membrane 14 is tough enough that by blowing air into the sealed interior of the mounting base 2, the sliding block 21 and the flexible membrane 14 can be reset. At the same time, the sliding rod 8 can be manually moved up to relock the limiting post 16 and the locking post 27, ready for the next use.

[0030] As attached Figure 6As shown, in a further embodiment, a limiting ring 23 is fixedly installed inside the slide tube 15. The center of the limiting ring 23 is a through hole. A groove 22 communicating with the slide tube 15 is formed on the side of the limiting ring 23 near the assembly column 7. The sliding block 21 is slidably and sealingly disposed in the slide tube 15 between the limiting ring 23 and the assembly column 7. The dimensions of the limiting ring 23 and the groove 22 match. In this embodiment, the frictional force on the inner wall of the slide tube 15 between the limiting ring 23 and the assembly column 7 gradually increases in the direction towards the docking cover 1. Therefore, during use, when oxygen cannot enter normally from the sliding cavity to supply training, the oxygen in the assembly cavity 6, intermediate channel 10, and docking cover 1 is consumed. Due to pressure changes, the sliding block 21 moves towards the nasal inhalation hole 24 in the sliding tube 15 until it falls into the drop groove 22. At this time, the space above the flexible membrane 14 is connected to the docking cover 1, and the pressure on it changes synchronously, causing the flexible membrane 14 to bulge. The bulging flexible membrane 14 pulls the pull rod 13 and the limiting post 16 upward, separating from the locking post 27 at the top of the sliding rod 8. The sliding rod 8 then performs a subsequent downward movement to automatically unlock. After use, the device is inverted so that the sliding block 21 falls back into the sliding tube 15. By blowing air into the sealed state inside the assembly seat 2, the sliding block 21 and the flexible membrane 14 are reset. At the same time, the sliding rod 8 is manually moved upward so that the limiting post 16 and the locking post 27 are locked together again, ready for the next use.

[0031] As attached Figure 7 As shown, in another specific embodiment, the outer wall of the mounting base 2 is provided with an elastic rubber cord 28 for fitting over the patient's head. This elastic rubber cord 28 facilitates the wearing and use of the device. When wearing the device, the patient can use the elastic rubber cord 28 to fix the device to their face, thus eliminating the need for hand support during rehabilitation exercises and improving the efficiency of the rehabilitation process. In this embodiment, the docking cover 1 can be made of flexible rubber material, and the outer wall shape of the docking cover 1 can be designed to perfectly fit the nasal cavity and mouth area. By limiting the material and shape of the docking cover 1, the airtightness of the mounting cavity 6 can be ensured when the patient wears the device, thus ensuring the effectiveness of respiratory resistance training.

[0032] In another specific embodiment, two nasal suction holes 24 may be provided, and both nasal suction holes 24 are connected to the aforementioned sliding cavity or assembly cavity 6. The corresponding arrangement of the two nasal suction holes 24 can enhance the usability of the device.

[0033] One specific embodiment of the present invention includes: an assembly base 2, one end of which is fixedly mounted with a docking cover 1, and the other end of which has an air inlet 25. The assembly base 2 has an assembly cavity 6 communicating with the air inlet 25 inside, and the inner wall of the docking cover 1 has two symmetrically arranged nasal inlets 24 communicating with the assembly cavity 6. The assembly base 2 has a sliding cavity identical to the assembly cavity 6 inside, and an adjustment mechanism is provided within the sliding cavity. The adjustment mechanism can change the resistance when oxygen enters the assembly cavity 6 through the air inlet 25. The adjustment mechanism includes a threaded column 3 slidably mounted inside the sliding cavity, an airbag 5 fixedly mounted at the end of the threaded column 3, a threaded groove on the outer wall of the threaded column 3, a first return spring 4 fixedly mounted at the bottom of the sliding cavity, the end of the first return spring 4 rotatably connected to the outer wall of the threaded column 3, and a locking unit inside the assembly base 2, which can form a snap-fit ​​design with the threaded groove. A release mechanism is also included, which can release the resistance to the air inlet 25 supplying oxygen to the assembly cavity 6.

[0034] In traditional Chinese medicine cardiovascular training, most patients improve their cardiovascular function through rehabilitation exercises such as Tai Chi and Baduanjin. However, these rehabilitation exercises are relatively slow and require long-term adherence. Furthermore, they do not include respiratory resistance training, which can effectively improve cardiovascular function, lower blood pressure, increase respiratory muscle strength, and promote cardiac rehabilitation. In this embodiment, an adjustment mechanism is provided to change the resistance to oxygen entering the assembly chamber 6 through the air inlet 25. This allows patients to adjust the resistance to oxygen inhalation according to their own condition when performing respiratory resistance training. By rotating the threaded column 3, it is displaced upwards under the action of the locking unit, thereby increasing the pressure of the threaded column 3 on the air bladder 5, and thus increasing the pressure inside the air bladder 5. As the air bladder 5 deforms further, the resistance increases, thus increasing the resistance to oxygen passing through it. This requires patients to exert more effort to inhale oxygen through their noses during breathing exercises, allowing for systemic oxygen supply. However, if an emergency occurs during breathing resistance training and the patient's breathing fails to draw oxygen from the inlet 25 into the assembly chamber 6, triggering a release mechanism, the locking unit's restriction on the threaded post 3 is released. Under the action of the first return spring 4, the threaded post 3 displaces downwards, relieving pressure on the air bladder 5. This removes the resistance to oxygen entering the assembly chamber 6 from the inlet 25, allowing the patient to breathe normally. This prevents accidents during breathing resistance training and reduces the risks associated with the training.

[0035] In another preferred embodiment of the present invention, the locking unit includes a sliding groove formed inside the mounting base 2, the sliding groove communicating with the interior of the sliding cavity. A threaded pin 17 is slidably installed in the sliding groove, and a top pin 26 is provided at one end of the threaded pin 17 near the sliding cavity. A magnetic block 20 is fixedly installed at the other end of the threaded pin 17. A limiting flange 19 is fixedly installed inside the sliding groove, and the threaded pin 17 slides inside the limiting flange 19. A third return spring 18 is fixedly installed between the limiting flange 19 and the top pin 26. The third return spring 18 and the threaded pin 17 are coaxially designed. In this embodiment, when the patient is performing respiratory resistance training, the threaded column 3 can be rotated. With the cooperation of the threaded column 3 and the threaded pin 17, the threaded column 3 can be moved upward and thus fixed. The upward movement of the threaded column 3 will apply pressure to the air bladder 5, thereby increasing the pressure inside the air bladder 5. The resistance to deformation of the air bladder 5 will increase, thereby allowing oxygen to enter the mounting cavity from the air inlet 25. The resistance at position 6 will increase, and the patient can adjust the number of turns of the threaded column 3 according to their own situation, thereby adjusting the breathing resistance. Under the action of the third return spring 18, the threaded pin 17, in cooperation with the limiting flange 19, always moves closer to the threaded column through the top pin 26, thereby locking the threaded pin 17 onto the threaded column 3. This prevents the threaded column 3 from shifting downward under the action of the first return spring 4, thus stabilizing the pressure exerted by the threaded column 3 on the airbag 5. This keeps the resistance to oxygen entering the assembly chamber 6 through the air inlet 25 unchanged, thereby allowing the patient to adjust the breathing resistance. Under the action of the release mechanism, the locking unit will cause the threaded pin 17 to shift to the other side, thereby releasing the lock on the threaded column 3. The threaded column 3 will then shift downward under the action of the first return spring 4, thereby releasing the pressure exerted on the airbag 5. The resistance to oxygen entering the assembly chamber 6 through the air inlet 25 will be released, allowing the patient to breathe normally and stop breathing resistance training.

[0036] In another preferred embodiment of the present invention, the release mechanism includes an assembly column 7 fixedly installed inside the assembly cavity 6. The end section of the assembly column 7 is tapered. A sliding rod 8 is slidably installed inside the assembly column 7. The sliding rod 8 passes through the outer wall of the assembly base 2. A magnetic flange 11 is fixedly installed on the outer wall of the sliding rod 8. A second return spring 9 is fixedly installed between the magnetic flange 11 and the bottom of the assembly column 7. The second return spring 9 and the sliding rod 8 are coaxial. The magnetic flange 11 can be magnetically attracted to the magnetic block 20 when it moves downward. A clamping unit is fixedly installed on the top of the sliding rod 8. The clamping unit can prevent the sliding rod 8 from moving downward.

[0037] In another preferred embodiment of the present invention, an intermediate channel 10 is further provided inside the assembly base 2. The two ends of the intermediate channel 10 are respectively connected to the assembly cavity 6 and the nasal suction hole 24. The clamping unit includes a locking post 27 fixedly installed on the top of the sliding rod 8. Multiple limiting balls 12 are slidably installed on the outer wall of the locking post 27. A flexible membrane 14 is fixedly installed on the top of the assembly post 7. A pull rod 13 is fixedly installed on the bottom of the flexible membrane 14. A limiting post 16 is fixedly installed on the end of the pull rod 13. The limiting post 16 can abut against the multiple limiting balls 12 to make it move outward. A sliding tube 15 is provided inside the assembly base 2. The sliding tube 15 connects with the nasal suction hole 24. The top of the assembly column 7 is connected to the slide tube 15. The flexible membrane 14 isolates the connection between the slide tube 15 and the assembly column 7. The slide tube 15 is equipped with a trigger unit, which can reduce the pressure inside the slide tube 15 and cause the flexible membrane 14 and the limiting column 16 to move upward. In this embodiment, the pull rod 13 and the limiting column 16 are integrated. When the patient is performing respiratory resistance training, the threaded pin 17 will lock the threaded column 3, so that the airbag 5 makes the resistance of oxygen entering the assembly cavity 6 through the air inlet 25 constant, thereby realizing the adjustable respiratory resistance training. The downward displacement of the magnetic flange 11 is restricted by the clamping unit. When the magnetic flange 11 1. When the magnetic flange 11 moves downward, it will magnetically attract the magnetic block 20, causing the threaded pin 17 to move closer to the sliding rod 8. This releases the locking of the threaded pin 17 onto the threaded post 3, and through the clamping unit, the sliding rod 8 is locked and cannot move downward, thus ensuring normal breathing resistance training. A locking post 27 is fixedly installed on the top of the sliding rod 8. Multiple limiting balls 12 are slidably installed in an array inside the locking post 27. Under the action of the limiting post 16, the limiting balls 12 slide a certain distance towards the outer wall of the locking post 27, thus preventing the assembly post 7 from moving downward, thereby ensuring that the magnetic flange 11 will not magnetically attract the magnetic block 20. This ensures that the threaded pin 17 is locked to the threaded post 3. When the trigger unit works, the limiting post 16 is displaced upward, and the limiting ball 12 slides into the locking post 27. As a result, the sliding rod 8 is displaced downward under the action of the second return spring 9, which drives the magnetic flange 11 to displace downward, so that it reacts with the magnetic block 20. This causes the threaded pin 17 to be displaced, the locking of the threaded pin 17 to the threaded post 3 is released, and the threaded post 3 is displaced downward under the action of the first return spring 4. This releases the resistance to oxygen entering the assembly cavity 6 through the air inlet 25, relieves the patient's breathing resistance training, and allows the patient to inhale oxygen normally.

[0038] In another preferred embodiment of the present invention, the triggering unit includes a sliding block 21 slidably installed inside the slide tube 15. A limiting ring 23 is fixedly installed inside the slide tube 15. The mounting base 2 has a groove 22 communicating with the slide tube 15. The limiting ring 23 matches the size of the groove 22. In this embodiment, when the patient is performing normal breathing resistance training, the sliding block 21 will move back and forth at a certain position inside the slide tube 15 between inhalation and exhalation. When a special situation occurs, such as the air inlet 25 is blocked or the air bag 5 malfunctions, and the patient cannot inhale the oxygen in the air inlet 25 into the mounting cavity 6, the patient will consume the oxygen in the mounting cavity 6 through the communication between the nasal inlet 24, the intermediate channel 10, and the mounting cavity 6, thereby activating the triggering unit. When the patient cannot inhale the oxygen in the air inlet 25 into the mounting cavity 6, the patient is still consuming the oxygen in the mounting cavity 6, which will cause the patient to pull the sliding block 21 outward, thus causing the sliding block 21 to move to one side of the slide tube 15, at the limiting ring 23. Under the action of the sliding block 21, the sliding block 21 will stop sliding when it reaches the position of the limiting ring 23 in the sliding tube 15. At this time, the sliding block 21 will fall into the groove 22 that matches its size. Due to the displacement of the sliding block 21, the volume between the sliding tube 15 and the sliding block 21 will increase and be in a low-pressure environment. The flexible membrane 14 will bulge upward, thereby driving the pull rod 13 to move upward, thereby driving the limiting post 16 to move upward. The limiting ball 12 inside the locking post 27 will move inward, thereby the sliding rod 8 will move downward under the action of the second return spring 9, thereby causing the magnetic flange 11 to have a magnetic attraction reaction with the magnetic block 20, thereby causing the threaded nail 17 to move closer to the magnetic flange 11, thereby releasing the locking of the threaded nail 17 to the threaded post 3. The threaded post 3 will move under the action of the first return spring 4, and the multi-pressure of the threaded post 3 on the airbag 5 will be released. Thus, the resistance of oxygen entering the assembly cavity 6 from the air inlet 25 will be released, and the patient's breathing resistance training will be released, thereby ensuring the safety of the patient to a certain extent in special circumstances.

[0039] In another preferred embodiment of the present invention, the frictional force on the inner wall of the slide tube 15 gradually increases in the direction toward the docking cover 1. In the second embodiment, during a normal inhalation and exhalation by the patient, the sliding resistance of the sliding block 21 within the slide tube 15 gradually increases. Therefore, during normal breathing resistance training, the sliding block 21 will not shift to the position of the groove 22 and fall into it. However, when the patient is performing breathing resistance training with the frictional force on the inner wall of the slide tube 15 gradually increasing in the direction toward the docking cover 1, if a special situation occurs and oxygen cannot be drawn from the air inlet 25 into the assembly cavity 6, At this time, the patient is still consuming oxygen inside the assembly cavity 6, so the sliding block 21 will continue to slide. Due to the restriction of the limiting ring 23, the sliding block 21 will fall into the groove 22, causing the flexible membrane 14 to bulge and drive the limiting post 16 to move upward. This causes the sliding rod 8 to move the magnetic flange 11 downward under the action of the second reset spring 9, thus causing a magnetic attraction reaction with the magnetic block 20, displacing the threaded nail 17, releasing the lock on the threaded post 3, and thus immediately stopping the patient's breathing resistance training. The patient can then breathe normally, ensuring the patient's safety during breathing resistance training.

[0040] In another preferred embodiment of the present invention, the airbag 5 is made of TPV material. The airbag 5 made of PBV material has the characteristics of high elasticity and high flexibility. It can be squeezed by the threaded column 3 to increase the internal pressure, thereby changing the resistance of oxygen entering the assembly cavity 6 through the air inlet 25. When the patient performs breathing resistance training, the airbag 5 also contracts and expands, which is also a test of the fatigue resistance of the airbag 5. PVB material has good fatigue resistance.

[0041] Working principle: When this TCM cardiovascular medicine clinical exercise device is in use, the device can adjust the resistance when oxygen enters the assembly chamber 6 through the air inlet 25 via the adjustment mechanism, so that the patient can perform breathing resistance training at different levels. When a special situation occurs during the patient's breathing resistance training, the trigger unit will be activated, thereby deactivating the mechanism and stopping the breathing resistance training immediately, thus improving the patient's safety during breathing resistance training.
