Description

Technical Field

[0001] The invention belongs to the technical field of obstructive pulmonary emphysema, and in particular relates to a multifunctional respiratory muscle training device for obstructive pulmonary emphysema. Background Art

[0002] Obstructive pulmonary emphysema is a common chronic obstructive pulmonary disease, which is mainly caused by abnormal and persistent expansion of the distal air cavity of the terminal bronchioles of the lungs, accompanied by destruction of the alveolar wall and bronchioles. This disease can cause patients to have symptoms such as dyspnea, cough, and sputum. As the disease progresses, respiratory function gradually declines, and the patient's activity endurance will also be greatly reduced. From a pathological and physiological point of view, patients with obstructive pulmonary emphysema have increased airway resistance and reduced lung elastic recoil. During the breathing process, the airway is closed during exhalation, and gas discharge is blocked, resulting in an increase in residual volume. This requires more energy to overcome resistance when breathing, and the burden on the respiratory muscles, especially the diaphragm and intercostal muscles, is increased.

[0003] Among the existing training devices, the devices integrating multiple breathing training are relatively large, making the devices extremely inconvenient to use, while the small and convenient training devices can only perform a single breathing training; at the same time, the training resistance cannot be adjusted, so that the devices cannot be effectively adjusted for patients with different conditions, resulting in limited and poor training effects;

[0004] Therefore, in response to the above technical problems, this solution proposes a multifunctional respiratory muscle training device for obstructive pulmonary emphysema. Summary of the invention

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] like Figure 1-6As shown, the upper end of the support assembly 1 is provided with an exhalation exercise assembly 4 connected to the breathing assembly 2; the rear end of the breathing assembly 2 is provided with an inhalation exercise assembly; the exhalation exercise assembly 4 includes a lifting cover 401, a lifting rack 402, a driven gear 403, a worm 405, a worm wheel 404, an adjustment connecting rod 406, a torsion knob 407, a torsion spring 408, and a connecting rod 409; the connecting rod 409 is fixedly connected to the support assembly 1 at both ends, and the driven gears 403 are symmetrically arranged at both ends of the connecting rod 409, and the middle A worm gear 404 is provided; torsion springs 408 are symmetrically provided on both sides of the worm gear 404 to be fixedly connected to the driven gears 403 on both sides, and a worm 405 is provided at the upper end to engage with the driven gears 403; an adjusting connecting rod 406 is provided at the rear end of the worm 405 to penetrate the support assembly 1 to set a torsion knob 407; a lifting gear is provided at the front end of the driven gear 403 to engage with the driven gear 403; a lifting cover 401 is provided at the upper end of the lifting gear to be slidably connected to the breathing assembly 2; the connecting rod 409 is respectively connected to the driven gears 403 on both sides and the turbine in the middle for rotation;

[0034] The support assembly 1 includes a telescopic belt 101, a support box 102, and a pressing hole 103; the support box 102 is fixedly connected to the telescopic belt 101 on both sides, the pressing holes 103 are symmetrically arranged on both sides of the front end, and the rear end is rotatably connected to the adjustment connecting rod 406;

[0035] The breathing assembly 2 comprises a breathing mask 201, a breathing duct 202, a shunt duct 203, a breathing training tank 204, and an air inlet pipe 205; the breathing training tanks 204 are symmetrically arranged on both sides of the supporting box 102; the shunt duct 203 is arranged on the upper end of the breathing training tank 204; the shunt duct 203 is connected to the middle part of the breathing duct 202; the breathing duct 202 is provided with a breathing mask 201 at the front end, and an air inlet pipe 205 is arranged at the rear end to be movably connected to the inhalation control assembly 3; the breathing training tank 204 is slidably connected to the lifting rod inside, and a plurality of air outlet holes 206 are arranged at the lower end, and the bottom is connected to the supporting box 102;

[0036] The pressing assembly 5 includes a telescopic slot 501, a sliding connecting rod 502, a telescopic rod 503, a connecting plate 504, and an elastic pressing plate 505; an annular telescopic slot 501 is provided on the driven gear 403 to be slidably connected to the sliding connecting rod; a telescopic rod 503 is provided at the rear end of the sliding connecting rod 502 to be slidably connected to the pressing hole 103, and the rear end is fixedly connected to the connecting plate 504; the rear end of the connecting plate 504 is fixedly connected to the elastic pressing plate; one end of the telescopic slot 501 is close to the center of the gear, and the other end is close to the edge of the gear;

[0037] In this embodiment, the working principle of the exhalation exercise component 4 is as follows: when the patient exhales, the exhaled gas pushes the lifting cover 401 in the breathing component 2 to slide down, and the lifting rack 402 is meshed with the driven gear 403. When the lifting rack 402 moves, it drives the driven gear 403 to rotate. When the lifting cover 401 slides down to the position of the air outlet 206, the air pressure in the breathing exercise tank 204 decreases, so that under the elastic action of the torsion spring 408, the driven gear 403 is reversed, pushing the rack up, so that the lifting cover 401 is reset;

[0038] When the resistance to exhalation needs to be adjusted, the torsion knob 407 can be rotated to drive the adjusting link 406 to rotate, thereby causing the worm 405 to rotate. The rotation of the worm 405 will drive the worm wheel 404 to rotate, thereby changing the relative position relationship between the worm wheel 404 and the driven gear 403, thereby adjusting the preload force of the torsion spring 408; when the preload force of the torsion spring 408 changes, the resistance felt by the patient when exhaling will change, so that the size of the exhalation resistance can be flexibly adjusted according to the patient's condition and training needs, thereby realizing personalized expiratory muscle training;

[0039] The working principle of the pressing assembly 5 is as follows: when the driven gear 403 rotates, the annular telescopic slot 501 installed on the driven gear 403 also rotates accordingly. When the telescopic slot 501 rotates, the sliding link 502 will slide and displace relatively in the telescopic slot 501. Due to the shape of the telescopic slot 501 with one end close to the center of the gear and the other end close to the edge of the gear, when the sliding link 502 moves in the telescopic slot 501, it will drive the telescopic rod 503 to slide in the pressing hole 103. As the telescopic rod 503 slides, the elastic pressing plate 505 will be pushed, thereby pressing the patient's abdomen. The pressing action is performed synchronously with the exhalation action, and the pressing force and frequency will change with the patient's exhalation and the rotation speed of the driven gear 403.

[0040] In this embodiment, the exhalation training component 4 generates an adjustable resistance when the patient exhales. The patient's expiratory muscles need to resist this resistance to exhale the gas, which effectively exercises the intercostal muscles, abdominal muscles and other expiratory muscles. As the training continues, the expiratory muscle strength is enhanced, which can better overcome the problems of increased airway resistance and reduced lung elastic recoil force when patients with obstructive pulmonary emphysema exhale, reduce residual gas volume, reduce respiratory muscle fatigue, and improve exhalation ability;

[0041] The pressing component 5 is linked with the exhalation training component 4, and the pressing is coordinated with the patient's exhalation action to assist the diaphragm to relax and strengthen the effect of abdominal breathing; long-term training helps patients to form a correct and efficient abdominal breathing pattern, so that the diaphragm can play a greater role in the breathing process, further improve respiratory function, reduce breathing difficulties, and improve patients' exercise endurance and quality of life.

[0042] Example 2

[0043] like Figure 1 , 6 As shown, the inhalation control assembly 3 includes a sealing ring 301, an adjusting spring 302, a push plate 303, an adjusting screw 304, and an adjusting knob 305; the adjusting screw 304 is threadedly connected to the rear end of the air intake pipe 205, a push plate 303 is arranged at the front end of the adjusting screw 304 to be fixedly connected to the adjusting spring 302, and an adjusting knob 305 is arranged at the rear end; the front end of the adjusting spring 302 is fixedly connected to the sealing ring 301; the inner diameter of the air intake pipe 205 is smaller than the inner diameter of the breathing pipe 202 and the inner diameter of the sealing ring 301, and a plurality of holes are provided at the rear end of the air intake pipe 205 for air intake;

[0044] In this embodiment, the working principle of the inhalation control component 3 is as follows: when the patient inhales, air tries to enter from the air inlet hole at the rear end of the air inlet pipe 205. Due to the pressure change of the sealing ring 301 on the air inlet pipe 205, the air will encounter different degrees of resistance when entering. If the pressure of the sealing ring 301 on the air inlet pipe 205 is relatively large, the air inlet hole will be blocked to a large extent by the sealing ring 301, and the resistance to air entering will be large; otherwise, the air inlet resistance will be small; the patient's inhalation muscles need to overcome the air inlet resistance generated by the sealing ring 301 before they can inhale air into the body. In this way, the inhalation control component 3 can flexibly adjust the inhalation resistance according to the patient's needs and condition, thereby achieving the purpose of exercising the inhalation muscles;

[0045] When the resistance needs to be adjusted, the adjusting knob 305 is rotated. Since the adjusting screw 304 is threadedly connected to the rear end of the air intake pipe 205, the adjusting screw 304 will move axially accordingly. The axial movement of the adjusting screw 304 will push the push plate 303, and the push plate 303 will then compress or relax the adjusting spring 302. The deformation of the adjusting spring 302 will change its force on the sealing ring 301. When the adjusting spring 302 is compressed, the sealing ring 301 will generate greater pressure on the rear end of the air intake pipe 205; when the adjusting spring 302 is stretched, the pressure of the sealing ring 301 on the rear end of the air intake pipe 205 is reduced.

[0046] In this embodiment, for patients with weak respiratory muscles, the intake resistance can be adjusted to a lower level so that the patients will not be too strenuous when inhaling, which helps them to gradually carry out inspiratory muscle training; and for patients with strong respiratory muscles or who have recovered after a period of training, the intake resistance can be appropriately increased to further strengthen the inspiratory muscle training and improve the training effect;

[0047] Both the inhalation control component 3 and the exhalation training component 4 have flexible resistance adjustment functions. Through personalized training settings, they can meet the training needs of different patients at different stages of their illness, ensure the effectiveness and safety of the training, and enable each patient to perform respiratory muscle training at a training intensity that suits them, thereby maximizing the training effect and promoting the recovery and improvement of respiratory function.

[0048] In summary, the present invention can comprehensively train the patient's inhalation and exhalation by integrating the inhalation control component 3 and the exhalation training component 4, thereby avoiding the limitation of a single breathing training method; the respiratory component 2 cooperates with the inhalation control component 3 and the exhalation training component 4 to simulate the coordinated training of inhalation and exhalation during the normal breathing process of the human body, thereby training the respiratory muscles more effectively; the support component 1 is arranged to be worn on the patient's abdomen, and a pressing component 5 is arranged at the lower end of the exhalation training component 4 to press the patient's abdomen; this helps the patient to perform abdominal breathing training, enhance the diaphragm function, enable the patient to exhale more thoroughly, further optimize the breathing pattern, and improve the breathing efficiency;

[0049] At the same time, by driving the worm 405 to rotate through the worm gear 404, the preload force of the torsion springs 408 at both ends can be adjusted, thereby adjusting the resistance of the lifting gear, so that the expiratory resistance can be personalized according to the severity of the disease, respiratory muscle strength, etc. of different patients, making the training more targeted and improving the training effect; compared with the existing device that integrates multiple breathing training but is relatively large, the structure of this device is more compact, avoiding the inconvenience caused by the large size of the device, making it convenient for patients to use in daily life, and improving patient compliance.
