Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation equipment technology, and in particular to a highly efficient respiratory rehabilitation training aid device. Background Technology

[0002] In recent years, the incidence of respiratory diseases in children has been rising year by year, while the prevalence of chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), chronic bronchitis, and emphysema in adults remains high. These diseases not only affect patients' respiratory function but may also lead to a decline in quality of life and even endanger their lives. Respiratory rehabilitation training, as one of the important means of treating these diseases, is becoming increasingly important.

[0003] Problems with existing respiratory rehabilitation training aids: Motion control incoordination: Early respiratory rehabilitation robots suffered from incoordination in the motion control of multi-degree-of-freedom motors, resulting in training movements being out of sync with the patient's breathing rhythm and affecting rehabilitation outcomes. For example, robot-assisted breathing may cause patient discomfort due to delays or excessive force.

[0004] Difficulty in quantifying parameters: As a core rehabilitation indicator, dyspnea currently lacks scientifically effective methods for quantification. Existing devices struggle to accurately assess changes in patients' respiratory muscle strength, leading to reliance on subjective judgment when adjusting training intensity, which can easily result in overtraining or undertraining.

[0005] Limited applicability: Some devices (such as high-frequency ventilation mode) have limited effectiveness for patients with severe respiratory dysfunction, and may even increase the work of breathing due to increased airway resistance, thus aggravating the condition.

[0006] A search revealed Chinese patent CN 120324860 B, which discloses an effective respiratory rehabilitation training aid device. The device includes a training mechanism comprising a breathing mask that covers the mouth, an arc-shaped slot in the center of the breathing mask, a soft silicone sleeve covering the surface of the arc-shaped slot, a distal tube connected to the back of the soft silicone sleeve, a locking device at the top center of the distal tube, the bottom of the locking device being locked to the top center of the distal tube, the soft silicone sleeve being detachable, the distal tube's end center being sealed to the end of a central cavity, and a display mechanism covering the outside of the distal tube. Using the breathing mask and arc-shaped slot, the user presses their mouth against the surface of the breathing mask, inflating the central cavity. The soft silicone sleeve covers the user's mouth, and the distal tube and locking device are fixed to the distal end. A U-shaped bracket and adjustment buttons are used to set specific numbers on the display screen.

[0007] The aforementioned existing technologies are complex in structure and lack portability, which limits patients' continuous training at home or when they go out, affects the rehabilitation effect, and cannot assist patients in expectoration during breathing training. Summary of the Invention

[0008] The existing technologies mentioned above have technical problems such as complex structure, single function, inability to assist in expectoration during patient breathing training, and insufficient portability, which limit patients' continuous training at home or when they are out.

[0009] Technical approach: Starting from the problems of existing technologies, this application provides an efficient respiratory rehabilitation training auxiliary device. It achieves synchronous training by combining a respiratory trainer with abdominal breathing, and integrates respiratory intensity detection and sputum clearance rehabilitation training methods through the setting of an exhalation detection mechanism and a back-patting mechanism, thereby greatly improving the training effect.

[0010] To achieve the above technical concept, the technical solution adopted by this invention is as follows: This application provides a high-efficiency respiratory rehabilitation training auxiliary device, including a respiratory trainer and a breathing mask. The respiratory trainer includes an abdominal inhalation mechanism and an exhalation detection mechanism connected to the breathing mask. The exhalation detection mechanism is used to detect the breathing intensity of the patient during the respiratory training process. It also includes a back-patting mechanism connected to the exhalation detection mechanism for assisting in sputum expectoration. The bottom of the back-patting mechanism is provided with a collection mechanism for collecting the sputum expelled by the patient and the exhaled carbon dioxide.

[0011] Furthermore, the abdominal inhalation mechanism includes an abdominal airbag and an air intake hood disposed inside the abdominal airbag. An air intake pipe is connected to the air intake hood, and the end of the air intake pipe is connected to a breathing mask.

[0012] In detail, the abdominal airbag is provided with air inlet valves on both sides, and an air inlet plate is provided at the position of the abdominal airbag air inlet valves. The air inlet plate has multiple air inlets, so that external air enters the abdominal airbag through the air inlets and air inlet valves.

[0013] Furthermore, a return spring is provided between the air intake hood and the abdominal airbag, and an inhalation one-way valve is provided at the end of the air intake pipe near the breathing mask.

[0014] Further, the technical solution includes an exhalation detection mechanism comprising an exhalation detection module and a set of outlet tubes connected to the end of a breathing mask. The exhalation detection module has an exhalation chamber, a piston cylinder is disposed within the exhalation chamber, a piston plate is slidably connected within the piston cylinder, a spring is disposed between the piston plate and the piston cylinder, and a set of pull ropes is connected to the piston plate. The pull ropes slidably pass through the piston cylinder and are connected to a piston cover. A set of air guide tubes is disposed at the bottom of the exhalation detection module, the air guide tubes are connected to the exhalation chamber, and the head end of the air guide tubes cooperates with the piston cover.

[0015] Specifically, the piston cylinder has a "mountain" shaped structure, the piston plate is slidably connected to the inside of the piston cylinder, one end of the spring is connected to the piston plate, and the other end is connected to the bottom of the piston cylinder.

[0016] Furthermore, the technical solution includes an exhalation one-way valve at the head end of the air outlet pipe, a piezoelectric control valve at the tail end, a spring 2 between the piston cover and the air guide pipe, a one-way valve inside the air guide pipe, and a back-patting mechanism connected to the tail end of the air guide pipe.

[0017] Further, the back-patting mechanism includes a back-patting module connected to an air duct. The back-patting module has upper and lower chambers. A vibration motor is installed in the upper chamber of the back-patting module. The vibration motor is electrically connected to a piezoelectric control valve. A vibrating plate for accelerating airflow circulation is installed at the end of the vibration motor.

[0018] Specifically, the vibrating plate is a stacked circular plate structure.

[0019] Furthermore, the technical solution further includes multiple air sleeves disposed in the upper chamber, with a slidably connected slapping block inside each air sleeve, the slapping block extending outside the back slapping module, and a spring three disposed between the air sleeves and the slapping block.

[0020] In detail, the air sleeve is a double-cavity sleeve structure, and a round hole is opened on the outer wall of the air sleeve. The striking block has an "I" shaped structure, and one end of the spring is connected to the striking block, while the other end is connected to the inner bottom of the air sleeve.

[0021] Furthermore, the collection mechanism includes a set of one-way valves connecting the upper and lower chambers, with a sputum container connected to the bottom of the one-way valves and a suction pump installed inside the sputum container.

[0022] Furthermore, the technical solution includes an air pressure sensor installed in the upper chamber, which is electrically connected to the suction pump. The lower chamber port is equipped with a cover, and both the cover and the sputum container have ventilation holes.

[0023] Specifically, the abdominal airbag, the exhalation detection module, and the back tapping module are connected by a connecting strap.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention combines abdominal breathing with an abdominal airbag during patient breathing training, allowing the gas in the airbag to reach the breathing mask through the inlet tube, thereby increasing the intensity of breathing training and aiding in subsequent rehabilitation.

[0025] 2. This invention utilizes the exhaled air during diaphragmatic breathing training, which enters the exhalation detection module through an exhaust tube. The air pushes a piston plate to slide within a piston cylinder, causing a pull rope to pull the piston cover, releasing the air passage and allowing the exhaled air to enter the back-patting module. When the piezoelectric control valve in the exhaust tube detects a high breathing intensity, it activates a vibration motor, causing a vibrating plate to vibrate and guide the air in the upper chamber of the back-patting module into the air sleeve. This air pressure then pushes the patting blocks to pat the patient's back, simulating manual back-patting to assist in expectoration. This combines training with expectoration therapy, helping to expel retained sputum from the patient's lungs and significantly improving the efficiency of breathing training.

[0026] 3. The present invention, through the setting of the collection mechanism, can collect the sputum expelled by the patient into the sputum box, effectively preventing the problem of contamination. Furthermore, through the cooperation of the air pump and the air pressure sensor, the gas in the back tapping module is always kept in the initial state, thereby ensuring that the overall structure maintains a continuous and normal operating state during the patient's continuous breathing training, and improving the automation of the structure.

[0027] 4. This invention connects the abdominal airbag, exhalation detection module, and back tapping module with a connecting strap to form a wearable strap structure, which is convenient to use, highly integrated, and effectively improves the efficiency and comfort of respiratory rehabilitation training.

[0030] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "front end", "rear end", "inner side", "outer side", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The inventors' research revealed that traditional respiratory rehabilitation requires professional guidance, relies on large equipment, and is difficult to popularize in home or community settings. Its functions are limited; some devices only provide basic respiratory muscle training and lack personalized, intelligent adjustment functions, failing to meet the diverse needs of different patients.

[0034] Based on the above findings, this application provides a highly efficient respiratory rehabilitation training aid device that integrates respiratory training, respiratory intensity detection, assisted expectoration, and sputum collection, thereby improving the efficiency and comfort of rehabilitation training.

[0035] Example 1 Reference Figure 1-7 As shown, this application provides a high-efficiency respiratory rehabilitation training auxiliary device, including a respiratory trainer and a breathing mask 1. The respiratory trainer includes an abdominal inhalation mechanism 2 and an exhalation detection mechanism 3 connected to the breathing mask 1. The exhalation detection mechanism 3 is used to detect the breathing intensity of the patient during the respiratory training process.

[0036] Preferably, the breathing mask 1 is made of medical-grade silicone material, with soft sealing pads designed at the edges to adapt to the facial contours of different patients and ensure airtightness. The breathing mask 1 is provided with an interface, the end of which is connected to the abdominal inhalation mechanism 2; the two sides of the interface are connected to the exhalation detection mechanism 3.

[0037] The abdominal inhalation mechanism 2 includes an abdominal airbag 21 and an air intake hood 22 disposed inside the abdominal airbag 21. An air intake pipe 23 is connected to the air intake hood 22, and the end of the air intake pipe 23 is connected to the breathing mask 1.

[0038] Preferably, the air inlet pipe 23 is a spiral flexible tube, which facilitates adjustment of direction and angle, and thus does not restrict the patient's position.

[0039] A return spring 24 is provided between the air intake hood 22 and the abdominal airbag 21, and an inhalation one-way valve is provided at the end of the air intake pipe 23 near the breathing mask 1.

[0040] When the patient uses the device, the abdominal air bladder 21 is placed against the patient's abdomen. When the patient inhales through the breathing mask 1, negative pressure is generated inside the breathing mask 1, and the one-way valve for inhalation opens. Simultaneously, as the patient performs abdominal inhalation, the abdomen protrudes, and the abdominal surface compresses the abdominal air bladder 21. Under the combined action of external pressure and the return spring 24, the air inside the abdominal air bladder 21 is forced into the respiratory tract through the inhalation mask 22 and the inhalation tube 23. This process couples abdominal movement with the inhalation action, requiring the patient to actively perform abdominal breathing to complete inhalation smoothly, thereby effectively exercising the diaphragm and abdominal muscles and forming a correct abdominal breathing pattern.

[0041] Furthermore, in order to detect and quantify the patient's expiratory intensity during the training process, an expiratory testing device 3 is provided.

[0042] The exhalation detection mechanism 3 includes an exhalation detection module 31 and two air outlet pipes 32 connected to both sides of the end interface of the breathing mask 1.

[0043] An exhalation one-way valve is provided at the end of the exhaust tube 32 near the breathing mask 1 to ensure that the exhaled air can only flow out of the breathing mask 1 and cannot flow back. A piezoelectric control valve 39 is provided at the tail end of the exhaust tube 32. The piezoelectric control valve 39 can be preset with different threshold values ​​to achieve different exhalation training difficulties.

[0044] The exhalation detection module 31 has an exhalation chamber, a piston cylinder 33 is provided in the exhalation chamber, a piston plate 34 is slidably connected in the piston cylinder 33, a spring 35 is provided between the piston plate 34 and the piston cylinder 33, and a set of pull ropes 36 are connected to the piston plate 34. The pull ropes 36 slide through the piston cylinder 33 and are connected to the piston cover 37.

[0045] The bottom of the exhalation detection module 31 is provided with a set of air guide tubes 38, which are connected to the exhalation chamber. The head end of the air guide tube 38 is engaged with the piston cover 37. A spring 310 is provided between the piston cover 37 and the air guide tube 38. When there is no external force, the air guide tube 38 is closed by the piston cover 37.

[0046] When the patient exhales, the exhaled air passes sequentially through the end interface of the breathing mask 1, the outlet tube 32, and the piezoelectric control valve 39. Finally, when it flows through the exhalation detection module 31, it enters the exhalation chamber and applies pressure to the piston plate 34. When the exhalation intensity (flow rate and pressure) reaches a certain threshold, which is sufficient to overcome the preload of the spring 35, the piston plate 34 is pushed to move.

[0047] The movement of piston plate 34 pulls piston cover 37 through pull rope 36, causing it to overcome the elastic force of spring 310 and leave the opening of air tube 38, thereby opening air tube 38 and allowing exhaled gas to enter air tube 38.

[0048] Preferably, a display screen can be installed at the end of the piston cylinder 33, and the position of the piston plate 34 can be detected in real time by a displacement sensor (such as a linear potentiometer or a Hall sensor, not shown in the figure), so as to accurately measure the patient's instantaneous expiratory intensity and expiratory flow rate. This signal can be transmitted to an external display screen or mobile APP to provide intuitive feedback to patients and doctors.

[0049] Example 2 Based on Example 1, referring to Figure 1-4As shown in Figures 8-13, in order to further enhance the effect of breathing training, breathing training is combined with assisted expectoration, which helps to expel sputum retained in the patient's lung tissue.

[0050] The breathing trainer also includes a back-patting mechanism 4 connected to the exhalation detection mechanism 3 for assisting in expectoration. The bottom of the back-patting mechanism 4 is provided with a collection mechanism 5, which is used to collect the sputum expelled by the patient and the carbon dioxide exhaled.

[0051] The back-tapping mechanism 4 includes a back-tapping module 41 connected to the air duct 38. The back-tapping module 41 has upper and lower chambers. A vibration motor 42 is installed in the upper chamber of the back-tapping module 41. The vibration motor 42 is electrically connected to a piezoelectric control valve 39, and a vibrating plate 43 is installed at the end of the vibration motor 42 to accelerate airflow circulation. The vibrating plate 43 vibrates at high speed with the vibration motor 42, and its blade structure accelerates gas circulation in the upper chamber, preventing localized airflow dead zones.

[0052] When the patient begins to exhale, the piezoelectric control valve 39 will trigger the vibration motor 42 to start when it reaches the predetermined threshold. This makes the back-patting action synchronized with the patient's exhalation, which is in line with physiological laws—patting during exhalation is more conducive to the movement of sputum.

[0053] Furthermore, the back-patting mechanism 4 also includes a plurality of air sleeves 44 disposed in the upper chamber, wherein a patting block 45 is slidably connected inside the air sleeve 44, and the patting block 45 extends outside the back patting module 41 so as to contact the lung area of ​​the patient's back, and a spring 46 that rebounds and reciprocates is disposed between the air sleeve 44 and the patting block 45.

[0054] When the patient exhales, the exhaled airflow is introduced into the upper chamber of the back-tapping module 41 through the air duct 38. At the same time, when the piezoelectric control valve 39 reaches the predetermined threshold, it triggers the vibration motor 42 to start. The airflow gathers in the upper chamber, causing its air pressure to rise instantaneously. This pressure acts on the surface of all the tapping blocks 45, pushing the tapping blocks 45 to move against the elastic force of the spring 3 46, thereby producing a collective tapping action on the patient's back.

[0055] As the intensity of exhalation decreases or inhalation begins, the pressure in the upper chamber drops, and the percussion block 45 quickly returns to its original position under the action of spring 46. This process repeats with the patient's next exhalation, creating a rhythmic and continuous percussion synchronized with the respiratory rate. The high-frequency mechanical vibration generated by the vibrating motor 42 driving the vibrating pad 43 is transmitted to the patient's skin through the percussion block 45, further helping to loosen and peel away sputum adhering to the bronchial walls.

[0056] Furthermore, the collection mechanism 5 for collecting sputum generated by the patient during training and expectoration includes a set of one-way valves 51 connecting the upper and lower chambers. The bottom of the one-way valves 51 is detachably connected to a sputum container 52, and an air pump 53 is installed inside the sputum container 52.

[0057] The upper chamber is equipped with a pressure sensor 54 for real-time monitoring of pressure changes in the upper chamber. The pressure sensor 54 is electrically connected to the air pump 53. The lower chamber port is equipped with a cover 55, and both the cover 55 and the sputum container 52 are provided with ventilation holes.

[0058] The sputum coughed up by the patient eventually enters the upper chamber of the back percussion module 41 along with the exhaled air through the airway 38. Under the influence of gravity, the sputum falls into the lower chamber through the recovery one-way valve 51 and finally enters the sputum container 52.

[0059] When a patient coughs up a large amount of sputum, causing a sudden increase in air pressure in the upper chamber, the pressure sensor 54 detects this signal. Then, as the patient alternates between inhaling, the suction pump 53 is activated. The suction pump 53 generates negative pressure, causing the recovery check valve 51 to open, thus drawing sputum and excess air into the sputum container 52 to prevent blockage of the tubing. When the air pressure returns to its initial state, the suction pump 53 automatically stops, and the exhaled air is discharged through the vent.

[0060] Preferably, a filter membrane can be installed on the vent holes of the sputum container 52 and the cover 55 to filter exhaled air, thereby allowing the air to be safely discharged and preventing environmental pollution. The sputum in the sputum container 52 can be removed and cleaned after training by opening the cover 55.

[0061] Preferably, the abdominal airbag 21, the exhalation detection module 31, and the back tapping module 41 are connected by a connecting strap to form a wearable "vest" structure, which is convenient for patients to wear and position, and ensures that each functional module is in the optimal working position.

[0062] Specific application examples The specific application of a high-efficiency respiratory rehabilitation training assistive device of this application in the rehabilitation treatment of chronic obstructive pulmonary disease is now described in detail with reference to Embodiment 1 and Embodiment 2.

[0063] Chronic obstructive pulmonary disease (COPD) is an airway disease that causes long-term breathing difficulties. Its main characteristic is narrowing or obstruction of the airways, leading to impaired airflow during breathing. Patients often experience symptoms such as coughing, sputum production, chest tightness, and shortness of breath. Although the condition gradually worsens, its progression can be controlled through prevention and proper treatment.

[0064] Chronic obstructive pulmonary disease (COPD) has become the fourth leading cause of death worldwide, affecting over 600 million people globally, with my country having the largest number of patients globally. With an aging population and a continuously rising incidence of respiratory diseases, pulmonary rehabilitation training as a non-pharmacological treatment is becoming increasingly important.

[0065] This application provides a highly efficient respiratory rehabilitation training aid device for lung rehabilitation training. The specific usage process is as follows: The patient wears a breathing trainer with a breathing mask 1 covering the mouth and nose. When the patient inhales through the breathing mask 1, negative pressure is generated inside the mask 1, and the one-way valve opens. Simultaneously, when the patient performs abdominal inhalation, the abdomen protrudes, and the abdominal surface compresses the abdominal air sac 21. Under the combined action of external pressure and the return spring 24, the air inside the abdominal air sac 21 is forced into the airway through the intake mask 22 and the intake tube 23.

[0066] When the patient exhales, the exhaled air passes sequentially through the end interface of the breathing mask 1, the outlet tube 32, and the piezoelectric control valve 39. Finally, when it flows through the exhalation detection module 31, it enters the exhalation chamber and applies pressure to the piston plate 34. When the exhalation intensity (flow rate and pressure) reaches a certain threshold, which is sufficient to overcome the preload of the spring 35, the piston plate 34 is pushed to move.

[0067] The movement of piston plate 34 pulls piston cover 37 through pull rope 36, causing it to overcome the elastic force of spring 310 and leave the opening of air tube 38, thereby opening air tube 38 and allowing exhaled gas to enter air tube 38.

[0068] Exhaled airflow is introduced into the upper chamber of the back-tapping module 41 through the air duct 38. At the same time, when the piezoelectric control valve 39 reaches the predetermined threshold, it triggers the vibration motor 42 to start. The airflow gathers in the upper chamber, causing its air pressure to rise instantaneously. This pressure acts on the surface of all the tapping blocks 45, pushing the tapping blocks 45 to move against the elastic force of the spring 3 46, thereby producing a collective tapping action on the patient's back.

[0069] As the intensity of exhalation decreases or inhalation begins, the pressure in the upper chamber drops, and the percussion block 45 quickly returns to its original position under the action of spring 46. This process repeats with the patient's next exhalation, creating a rhythmic and continuous percussion synchronized with the respiratory rate.

[0070] By tapping the area corresponding to the lungs on the patient's back, it helps the patient expel retained sputum during breathing training. The sputum coughed up is eventually carried by the exhaled air through the airway 38 into the upper chamber of the back tapping module 41. Under the influence of gravity, the sputum falls into the lower chamber through the recovery one-way valve 51 and finally enters the sputum box 52.

[0071] When a patient coughs up a large amount of sputum, causing a sudden increase in air pressure in the upper chamber, the pressure sensor 54 detects this signal. Then, as the patient alternates between inhaling, the suction pump 53 is activated. The suction pump 53 generates negative pressure, causing the recovery check valve 51 to open, thus drawing sputum and excess air into the sputum container 52 to prevent blockage of the tubing. When the air pressure returns to its initial state, the suction pump 53 automatically stops, and the exhaled air is discharged through the vent.

[0072] It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this invention, and these should also be considered within the scope of protection of this invention. These modifications and improvements will not affect the effectiveness of the invention or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
