Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a breathing training chair based on diaphragmatic breathing. Background Technology

[0002] A breathing trainer is a Class II medical device that actively enhances respiratory muscle strength and improves lung function through physical resistance, pressure, vibration, or feedback mechanisms. Its core mechanism is to increase respiratory resistance / load, train respiratory muscles such as the diaphragm and intercostal muscles, and provide visual / sensory feedback to guide standardized abdominal breathing.

[0003] Routine breathing training (such as home rehabilitation for patients with COPD and asthma): abdominal breathing is preferred. Long-term training can improve lung function and reduce the risk of acute exacerbations. It is the core breathing training method recommended in respiratory nursing.

[0004] Abdominal breathing (diaphragmatic breathing): The diaphragm is the main driving force. During inhalation, the diaphragm contracts and descends, the abdomen bulges, the thoracic cavity volume increases, and the lower part of the lungs fully expands. During exhalation, the diaphragm relaxes and rises, the abdomen retracts, the thoracic cavity volume decreases, and the air is fully expelled.

[0005] For example, Chinese invention patent CN115501554B discloses a respiratory muscle resistance training device and its usage method. It relates to the field of medical assistive recovery devices. An abdominal training elastic band passes through the seat and fits against the patient's abdomen via abdominal seat rollers. A backrest pusher pushes the upper backrest base, causing the backrest to rotate and assisting the patient in chest-opening movements. A chest training elastic band passes through the seat and fits against the patient's chest via chest seat rollers. A shoulder-pressing arm abuts against the patient's shoulder and applies pressure through a shoulder return spring, assisting the patient in shoulder-lowering movements. The abdominal and chest training elastic bands can apply resistance and restrict movement to the target muscles under the drive of abdominal and chest contraction motors. This invention can perform abdominal and chest breathing training through the abdominal and chest contraction modules, achieving training of respiratory muscle endurance and strength under both breathing modes. The backrest pusher and shoulder-pressing modules assist the patient in adjusting breathing posture and movement frequency.

[0006] Analysis of the aforementioned patents and existing technologies reveals that current breathing training devices lack integration of diaphragmatic breathing with the training device, and rely on manual switching when switching between exhalation and inhalation, failing to automatically switch in conjunction with diaphragmatic breathing, making them inconvenient. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention proposes a breathing training chair based on diaphragmatic breathing, which solves the technical problems mentioned in the background art, namely, the lack of integration between diaphragmatic breathing and the training device, the reliance on manual switching when switching between exhalation and inhalation, the inability to automatically switch in conjunction with diaphragmatic breathing, and the lack of convenience.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a breathing training chair based on diaphragmatic breathing, comprising: The main body has a first sliding groove. A control component is arranged on the main body, the control component including a Y-channel slider, the Y-channel slider being able to slide back and forth in the first groove to control the switching of airflow direction; A breathing assembly is disposed on the main body, one end of which is connected to the Y-channel slider; a binding assembly is fixedly installed on the main body at one end and fixedly connected to the control assembly at the other end, and the binding assembly can periodically exert force on the Y-channel slider with the rise and fall of the abdomen during breathing. A training component is mounted on the main body and is rotatable, and the training component is connected to the control component via a first hose and a second hose; An adjustment component is arranged on the main body and snaps into the training component, which can fix the position and angle of the training component.

[0009] Furthermore, the main body is provided with a first pipe and a second pipe, and the first pipe is connected to the first flexible hose, and the second pipe is connected to the second flexible hose.

[0010] Furthermore, the Y-channel slider includes a first branch pipe, a second branch pipe, and a third branch pipe, each of which is connected to the outside at one end and intersects with each other at the other end.

[0011] Furthermore, the control component also includes a first limiting block, a second limiting block, a traction slider, a first elastic element, and a second elastic element. The first limiting block and the second limiting block are fixedly disposed within the first sliding groove. The Y-channel slider can slide between the first limiting block and the second limiting block. When the Y-channel slider abuts against the first limiting block, the first branch pipe is connected to the first pipe. When the Y-channel slider abuts against the second limiting block, the second branch pipe is connected to the second pipe. The traction slider is slidably disposed within the first sliding groove. One end of the first elastic element is connected to the main body, and the other end is connected to the Y-channel slider. One end of the second elastic element is connected to the Y-channel slider, and the other end is connected to the traction slider.

[0012] Furthermore, the breathing assembly includes a breathing tube and a mouthpiece. The breathing tube is slidably disposed on the main body, and one end is connected to the third branch tube. The mouthpiece is detachably installed on the end of the breathing tube away from the third branch tube.

[0013] Furthermore, the binding assembly includes a first binding strap and a second binding strap. One end of the first binding strap is fixedly disposed on the main body, and the other end is provided with a Velcro A side. One end of the second binding strap is fixedly connected to the traction slider, and the other end is provided with a Velcro B side.

[0014] Furthermore, the training component includes an air cylinder and a sphere. The air cylinder is mounted on the main body and is rotatable. One end of the air cylinder is connected to the first hose, and the other end is connected to the second hose. The sphere is slidably arranged inside the air cylinder. A first one-way valve is provided at the end of the air cylinder near the first hose, and a second one-way valve is provided at the end of the air cylinder near the second hose.

[0015] Furthermore, the adjustment component includes an adjustment bracket and a second slide groove. The adjustment bracket is fixedly mounted on the main body. The second slide groove is formed on the adjustment bracket, and the air cylinder can slide within the second slide groove. A plurality of positioning strips that also serve as indicators are also arranged in a ring on one side of the second slide groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves the organic integration of breathing training and abdominal breathing. Through a binding component, it directly senses changes in abdominal movement, transforming the physiological activity of abdominal breathing into mechanical motion. The natural rise and fall of the abdomen during breathing drives the Y-channel slider to slide back and forth within the first groove, automatically switching between inhalation and exhalation channels without manual operation. This aligns with the natural rhythm of abdominal breathing, improving the convenience and effectiveness of training.

[0017] 2. Adjustable training resistance is provided. Through the combination of the air pump and the ball in the training component, as well as the adjustable design of the air pump angle, patients can adjust the training difficulty according to their own situation; the locking strip on the adjustment component can intuitively display the training intensity, making it easy for doctors or patients to keep track of the training progress.

[0018] 3. The structure is reasonably designed and comfortable to use. The breathing tube in the breathing assembly is adjustable and the mouthpiece is detachable and replaceable, which improves the convenience and hygiene of use; the binding assembly uses Velcro connection, which is convenient to wear and adjust, and can meet the needs of patients of different body types.

[0019] 4. Through the cooperation of elastic elements, the automatic reset and stable position maintenance of the Y-channel slider are achieved, ensuring the accuracy and reliability of airflow switching and improving the working stability of the device. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0024] Example: like Figure 1As shown, this invention provides a breathing training chair based on diaphragmatic breathing, including a main body 101 with a first groove 102. A control component is arranged on the main body 101, including a Y-channel slider 201, which can slide back and forth within the first groove 102 to control the switching of airflow direction. A breathing component is disposed on the main body 101, with one end connected to the Y-channel slider 201. A binding component is fixedly mounted at one end on the main body 101 and fixedly connected to the control component at the other end, and the binding component can periodically exert force on the Y-channel slider 201 with the rise and fall of the abdomen during breathing. A training component is disposed on the main body 101 and can rotate, and the training component is connected to the control component through a first hose 103 and a second hose 104. An adjustment component is disposed on the main body 101 and engages with the training component to fix the position and angle of the training component.

[0025] like Figure 3 , 4 As shown, the main body 101 also has a first pipe 105 and a second pipe 106, and the first pipe 105 is connected to the first flexible hose 103, and the second pipe 106 is connected to the second flexible hose 104. The Y-channel slider 201 includes a first branch pipe 107, a second branch pipe 108 and a third branch pipe 109, all of which are connected to the outside at one end and intersect at the other end.

[0026] like Figure 2 As shown, the control assembly also includes a first limiting block 202, a second limiting block 203, a traction slider 204, a first elastic element 205, and a second elastic element 206. The first limiting block 202 is fixedly disposed within the first slide groove 102. The second limiting block 203 is fixedly disposed within the first slide groove 102, and the Y-channel slider 201 can slide between the first limiting block 202 and the second limiting block 203. When the Y-channel slider 201 abuts against the first limiting block 202, the first branch pipe 107 is connected to the first pipe 105 (at this time, the second branch pipe 108 is blocked and in a non-connected state); when the Y-channel slider 201 abuts against the second limiting block 203, the second branch pipe 108 is connected to the second pipe 106 (at this time, the first branch pipe 107 is blocked and in a non-connected state). The traction slider 204 is slidably disposed within the first slide groove 102. One end of the first elastic element 205 is connected to the main body 101, and the other end is connected to the Y-channel slider 201. One end of the second elastic element 206 is connected to the Y-channel slider 201, and the other end is connected to the traction slider 204.

[0027] When the patient inhales, the diaphragm contracts and descends, causing the abdomen to bulge. This abdominal expansion pulls the first strap 301 and the second strap 302 outwards. The second strap 302 pulls the traction slider 204 to slide within the first groove 102. The traction slider 204, through the second elastic element 206, moves the Y-channel slider 201 towards the second limiting block 203 (the elastic force of the first elastic element 205 and the second elastic element 206 is preferably set to be the same, so that the sensitivity of the Y-channel slider 201 will be better). During exhalation, the abdomen contracts, and the Y-channel slider 201 moves to the first limiting block 202 under the pulling force of the first elastic element 205.

[0028] like Figure 1 As shown, the breathing assembly includes a breathing tube 207 and a mouthpiece 208. The breathing tube 207 is slidably mounted on the main body 101, with one end connected to the third branch tube 109, and can move together with the Y-channel slider 201. The mouthpiece 208 is detachably mounted on the end of the breathing tube 207 away from the third branch tube 109.

[0029] like Figure 2 As shown, the binding assembly includes a first binding strap 301 and a second binding strap 302. One end of the first binding strap 301 is fixedly mounted on the main body 101, and the other end is provided with a Velcro A side. One end of the second binding strap 302 is fixedly connected to the traction slider 204, and the other end is provided with a Velcro B side. In use, the first binding strap 301 and the second binding strap 302 are wrapped around the patient's abdomen for fixation, and the Velcro A side and the Velcro B side are adhesively connected.

[0030] like Figure 5 As shown, the training assembly includes an air cylinder 303 and a sphere 304. The air cylinder 303 is mounted on the main body 101 and is rotatable. One end of the air cylinder 303 is connected to a first flexible hose 103, and the other end is connected to a second flexible hose 104. The sphere 304 is slidably arranged inside the air cylinder 303. A first one-way valve 305 is provided at the end of the air pump 303 near the first hose 103, and a second one-way valve 306 is provided at the end of the air pump 303 near the second hose 104. Specifically, when inhaling, the abdomen expands, and the breathing tube 207, third branch tube 109, second branch tube 108, second pipe 106, second hose 104, and first one-way valve 305 form an airflow channel. Air enters from the first one-way valve 305 (that is, from the bottom of the air pump 303) and pushes the ball 304 upward. When exhaling, the abdomen contracts, and the breathing tube 207, third branch tube 109, first branch tube 107, first pipe 105, first hose 103, and second one-way valve 306 form an airflow channel. Air is discharged from the second one-way valve 306 (it should be noted that at this time, the airflow still goes upward from the bottom of the air pump 303, but it no longer comes out from the first one-way valve 305 but from the first hose 103). This achieves the function of automatic switching.

[0031] like Figure 5As shown, the adjustment assembly includes an adjustment bracket 307 and a second slide 308. The adjustment bracket 307 is fixedly mounted on the main body 101. The second slide 308 is formed on the adjustment bracket 307, and the air cylinder 303 can slide within the second slide 308. A plurality of locking strips 309, which also serve as indicators, are also arranged in a ring on one side of the second slide 308.

[0032] Specific usage and beneficial effects of the present invention: When using the device, the patient sits on the breathing training chair, and the first strap 301 and the second strap 302 are wrapped around the abdomen to secure it. The Velcro is adjusted to ensure the straps are snug but not too tight. The patient then holds the mouthpiece 208 in their mouth and begins abdominal breathing training.

[0033] When the patient inhales, the diaphragm contracts and descends, causing the abdomen to bulge. This abdominal expansion pulls the first strap 301 and the second strap 302 outwards. The second strap 302 pulls the traction slider 204 to slide within the first groove 102. The traction slider 204, through the second elastic element 206, moves the Y-channel slider 201 towards the second limiting block 203 until the Y-channel slider 201 abuts against the first limiting block 202. At this time, the first branch tube 107 connects to the first pipe 105, opening the inspiratory passage. When the patient inhales, the breathing tube 207, the third branch tube 109, the second branch tube 108, the second pipe 106, the second flexible tube 104, and the first one-way valve 305 form an airflow channel. Air enters through the first one-way valve 305 (i.e., from the lower part of the air cylinder 303), pushing the sphere 304 upwards. The gravity of the sphere 304 provides inspiratory resistance, enhancing inspiratory muscle strength.

[0034] When the patient exhales, the diaphragm relaxes and rises, the abdomen retracts, and the first elastic element 205 pushes the Y-channel slider 201 towards the second limiting block 203 until the Y-channel slider 201 abuts against the first limiting block 202. At this time, the second branch tube 108 connects with the second pipe 106, and the expiratory passage is opened. When the patient exhales, the breathing tube 207, the third branch tube 109, the first branch tube 107, the first pipe 105, the first flexible tube 103, and the second one-way valve 306 form an airflow channel, and air is discharged from the second one-way valve 306 (it should be noted that at this time, the airflow still goes upward from the bottom of the air cylinder 303, but no longer from the first one-way valve 305 but from the first flexible tube 103). The gravity of the sphere 304 provides expiratory resistance and enhances expiratory muscle strength.

[0035] By adjusting the position of the air cylinder 303 within the second slide groove 308, the tilt angle of the air cylinder 303 can be changed, thereby adjusting the resistance generated when the ball 304 slides, adapting to the training needs of different patients. The positioning strip 309 indicates the current training intensity level.

[0036] This invention uses a strap-on component to sense abdominal movement and automatically switch between inhalation and exhalation channels, achieving an organic integration of breathing training and diaphragmatic breathing. It requires no manual operation, conforms to the natural rhythm of diaphragmatic breathing, and improves the convenience and effectiveness of training. Simultaneously, the adjustable training resistance design allows patients to adjust the training difficulty according to their own situation, gradually improving respiratory muscle strength and lung function.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
