Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically an intelligent breathing trainer for elderly patients with chronic obstructive pulmonary disease. Background Technology

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease in the elderly, characterized by persistent and progressive airflow limitation. The main symptoms include chronic cough, sputum production, shortness of breath or dyspnea on exertion. Etiology is often related to long-term smoking, air pollution, occupational dust exposure, and recurrent respiratory infections. Due to physiological decline in lung function, symptoms are more pronounced in the elderly, and complications such as respiratory failure and heart failure are more likely to occur. Diagnosis relies heavily on pulmonary function tests, combined with symptom assessment, medical history, and chest imaging to rule out other diseases. Treatment and management prioritize smoking cessation, supplemented by medications such as bronchodilators, long-term home oxygen therapy, and rehabilitation training. Vaccination and avoiding exposure to cold are also important to prevent acute exacerbations. Medication dosage adjustments are necessary for the elderly, and medical attention should be sought promptly if symptoms worsen.

[0003] To improve respiratory function, patients need to use respiratory trainers for training. Most current respiratory trainers consist of a body, a breathing channel, and a mouthpiece. The connection between the mouthpiece and the breathing channel is mostly achieved by simply placing the mouthpiece over the outside of the breathing channel. Although this method is simple to operate, the fixation between the mouthpiece and the breathing channel is not secure enough. The mouthpiece may fall off during training, which seriously affects the normal progress of respiratory training. At the same time, there is no sealing mechanism between the mouthpiece and the breathing channel. The interference fit between the two cannot ensure a seal. Insufficient sealing will directly affect the core function and safety of the respiratory trainer. Therefore, those skilled in the art have proposed an intelligent respiratory trainer for elderly patients with chronic obstructive pulmonary disease to solve the problems mentioned in the background art. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an intelligent breathing trainer for elderly patients with chronic obstructive pulmonary disease, which solves the problems of the mouthpiece not being able to be securely fixed and sealed in the prior art.

[0005] A smart breathing trainer for elderly patients with chronic obstructive pulmonary disease includes a body, a display screen on the top surface of the body, a breathing channel on the top of the body located to one side of the display screen, an annular mounting base fixedly connected to the body around the breathing channel, a mouthpiece movably connected between the mounting base and the breathing channel, and a sealing component and a fixing component disposed inside the mounting base; the sealing component is used to enhance the seal between the mouthpiece and the breathing channel, and the fixing component is used to securely fix the mouthpiece to the outer periphery of the breathing channel.

[0006] Preferably, the sealing assembly includes a mounting groove, a sealing ring, an air chamber, a piston, and a connecting hole. The mounting groove is annular and located on the inner surface of the mounting base. The sealing ring is made of rubber and is hollow inside. The sealing ring is installed inside the mounting groove, and its outer diameter matches the inner diameter of the mounting groove. The air chamber is located inside the mounting base. The piston is slidably connected to the air chamber and its size matches the air chamber. The outer circumference of the piston is tightly fitted to the inner wall of the air chamber. The connecting hole is located on one side of the inner wall of the air chamber and communicates with the inside of the sealing ring to allow gas flow between the air chamber and the sealing ring.

[0007] Preferably, the sealing assembly further includes a first groove, a first slider, a first spring, and a connecting rod. The first groove is formed on the top surface of the mounting base and one end is connected to the end of the air chamber away from the connecting hole. The first slider is slidably connected to the first groove and its shape matches the first groove. The first spring is installed inside the first groove and its two ends are respectively fixedly connected to the inner wall of the first slider away from the air chamber and the first groove away from the air chamber, so that the first slider is held in the initial position close to the air chamber in its natural state. The connecting rod is movably connected to the communication area between the air chamber and the first groove, and its two ends are respectively fixedly connected to the side of the piston away from the connecting hole and the side of the first slider close to the connecting hole, so as to realize the synchronous linkage between the first slider and the piston.

[0008] Preferably, the fixing component includes a cavity, a through groove, a top block, and a clamping block. The cavity is annular and is located inside the mounting base and below the air cavity, and is coaxially arranged with the mounting base. The through groove penetrates the inner wall of the cavity near the center of the mounting base, and at least three are evenly distributed along the circumference of the cavity. The top block is slidably connected to the through groove and the number of top blocks is the same as the number of through grooves. The end of the top block away from the center of the mounting base is arc-shaped. The clamping block is arc-shaped and fixedly connected to the end of the top block near the center of the mounting base. The inner surface of the clamping block is provided with anti-slip texture, and its curvature is adapted to the outer circumference curvature of the bite.

[0009] Preferably, the fixing assembly further includes a rotating ring, an arc-shaped block, a connecting groove, and a connecting block. The rotating ring is rotatably connected to the inside of the cavity, coaxially arranged with the cavity, and can rotate freely in the circumferential direction. The arc-shaped blocks are fixedly connected to the side of the rotating ring near the center of the mounting base, the number of which is the same as the top block and evenly distributed along the circumference of the rotating ring. The arc-shaped surface of the arc-shaped block is adapted to the arc-shaped end of the top block. The connecting groove is opened in the inner wall of the top of the cavity and communicates with the first sliding groove. The connecting block is fixedly connected to the top of the rotating ring and one side of the first slider, and slidably connected inside the connecting groove, for realizing the linkage between the first slider and the rotating ring, driving the rotating ring to rotate synchronously.

[0010] Preferably, the fixing component further includes a second slide groove, a second slider, and a second spring. The second slide groove is formed on the inner wall of the bottom of the cavity and is located below the top block, and the number of slide grooves is the same as that of the top block. The second slider is fixedly connected to the bottom of the top block and slidably connected to the second slide groove, and its shape matches the second slide groove. The second spring is installed inside the second slide groove and its two ends are respectively fixedly connected to the inner wall of the second slider near the center of the mounting base and the second slide groove near the center of the mounting base. In its natural state, when the top block is pulled into the cavity, the elastic force of the first spring is greater than the sum of the elastic forces of all the second springs, ensuring that the first spring can push the top block to move towards the center of the mounting base when it rebounds.

[0011] Preferably, the mouthpiece is made of medical-grade silicone material, with an arc-shaped top to fit the oral cavity biting structure, and an annular groove on the inner side of the bottom to fit the outer periphery of the breathing channel for precise docking with the breathing channel.

[0012] Preferably, the display screen is a touch screen for displaying breathing training parameters, training duration and device working status. The body is equipped with a battery compartment and a control module. The control module is electrically connected to the display screen. The bottom of the body is equipped with an anti-slip pad, and the sides are equipped with arc-shaped grooves for easy gripping. The surface of the body is treated with an antibacterial coating.

[0013] Preferably, the thickness of the sealing ring is greater than the depth of the mounting groove, ensuring that the sealing ring can fully press against the outer periphery of the bite when it expands, thereby achieving a sealing effect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention features a sealing assembly. A first slider slides along a first groove, compressing a first spring. During this process, a connecting rod drives a piston within the air chamber, moving synchronously with the first slider. Air from the sealing ring is drawn into the air chamber through a connecting hole, causing the sealing ring to shrink. When the sealing ring shrinks to the point of being submerged in the mounting groove, the bottom of the mouthpiece is placed around the breathing channel. Then, the first slider is released, and the connecting rod drives the piston to move in the opposite direction with the first slider. Air from the air chamber is then sent into the sealing ring through the connecting hole, causing it to expand. When the sealing ring expands to the point where the mouthpiece and breathing channel fit tightly together, a seal is achieved between the mouthpiece and the breathing channel. This design effectively enhances the seal between the mouthpiece and the breathing channel, thus ensuring the effectiveness of breathing training.

[0016] 2. This invention features a fixing component. When the first slider slides along the first groove and compresses the first spring, the connecting block drives the rotating ring and the arc-shaped block to move synchronously within the cavity with the first slider. When the arc-shaped block moves away from behind the top block, the second spring rebounds and, through the second slider, drives the top block and the clamping block to move into the cavity. When the first spring rebounds, the first slider, through the connecting block, drives the rotating ring and the arc-shaped block to move in the opposite direction. When the arc-shaped block contacts the top block, because the elastic force of the first spring is greater than the sum of the elastic forces of all the second springs, the arc-shaped block pushes the top block towards the center of the mounting base and compresses the second spring through the second slider. When the clamping block moves with the top block to fit tightly against the mouthpiece, it can be fixed to the outside of the breathing channel. This design allows the mouthpiece to be firmly fixed to the outer periphery of the breathing channel, effectively preventing the mouthpiece from falling off and affecting the normal training process.

[0024] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] Example 1: This invention provides an intelligent breathing trainer for elderly patients with chronic obstructive pulmonary disease, comprising a body 1, a display screen 2 on the top surface of the body 1, a breathing channel 3 on the top of the body 1 located to one side of the display screen 2, an annular mounting base 5 fixedly connected to the body 1 on the outer periphery of the breathing channel 3, a mouthpiece 4 movably connected between the mounting base 5 and the breathing channel 3, and a sealing assembly 6 inside the mounting base 5, the sealing assembly 6 comprising a mounting groove 61, a sealing ring 62, an air chamber 63, a piston 64, a connecting hole 65, a first sliding groove 66, a first slider 67, a first spring 68, and a connecting rod 69;

[0027] The mouthpiece 4 is made of medical-grade silicone. Its top is arc-shaped to fit the oral cavity's biting structure, and the bottom inner side is provided with an annular groove that fits the outer periphery of the breathing channel 3 for precise docking with the breathing channel 3. The display screen 2 is a touch screen used to display breathing training parameters, training duration, and device working status. The body 1 contains a battery compartment and a control module. The control module is electrically connected to the display screen 2. The bottom of the body 1 is provided with an anti-slip pad, and the sides are provided with arc-shaped grooves for easy gripping. The surface of the body 1 is treated with an antibacterial coating.

[0028] In one embodiment of the present invention, the mounting groove 61 is annular and is formed on the inner surface of the mounting base 5. The sealing ring 62 is made of rubber and is hollow inside. The sealing ring 62 is installed inside the mounting groove 61, and its outer diameter is adapted to the inner diameter of the mounting groove 61. The air chamber 63 is formed inside the mounting base 5. The piston 64 is slidably connected to the air chamber 63 and its size is adapted to the air chamber 63. The outer periphery of the piston 64 is tightly fitted to the inner wall of the air chamber 63. The connecting hole 65 is formed on one side inner wall of one end of the air chamber 63 and communicates with the inside of the sealing ring 62 to realize gas flow between the air chamber 63 and the sealing ring 62. The first sliding groove 66 is formed on the top surface of the mounting base 5 and one end is connected to the end of the air chamber 63 away from the connecting hole 65. The first slider 67 is slidably connected to the first sliding groove. 66, whose shape matches the first slide groove 66, the first spring 68 is installed inside the first slide groove 66 and its two ends are respectively fixedly connected to the side of the first slider 67 away from the air chamber 63 and the inner wall of the first slide groove 66 away from the air chamber 63. In its natural state, it keeps the first slider 67 in the initial position close to the air chamber 63. The connecting rod 69 is movably connected to the communication area between the air chamber 63 and the first slide groove 66. Its two ends are respectively fixedly connected to the side of the piston 64 away from the connecting hole 65 and the side of the first slider 67 close to the connecting hole 65, so as to realize the synchronous linkage between the first slider 67 and the piston 64. The thickness of the sealing ring 62 is greater than the depth of the mounting groove 61, ensuring that the sealing ring 62 can fully press against the outer periphery of the bite 4 when it expands, so as to achieve the sealing effect.

[0029] During operation, the first slider 67 slides along the first groove 66 to compress the first spring 68. During this process, the connecting rod 69 drives the piston 64 to move synchronously with the first slider 67 in the air chamber 63 and draws the air in the sealing ring 62 into the air chamber 63 through the connecting hole 65, causing it to shrink. When the first slider 67 is released, the first spring 68 rebounds, and the piston 64 moves in the opposite direction through the first slider 67 and the connecting rod 69, and sends the air in the air chamber 63 into the sealing ring 62 through the connecting hole 65, causing it to expand.

[0030] Example 2: This example is basically the same as the previous example, except that a fixing component 7 is also provided inside the mounting base 5. The fixing component 7 includes a cavity 71, a through groove 72, a top block 73, and a clamping block 74. The cavity 71 is annular and is opened inside the mounting base 5 and below the air cavity 63. It is coaxially arranged with the mounting base 5. The through groove 72 penetrates the inner wall of the cavity 71 near the center of the mounting base 5 and is evenly distributed with at least 3 grooves along the circumference of the cavity 71. The top block 73 is slidably connected to the through groove 72 and the number of top blocks 73 is the same as that of the through groove 72. The end of the top block 73 away from the center of the mounting base 5 is arc-shaped. The clamping block 74 is arc-shaped and fixedly connected to the end of the top block 73 near the center of the mounting base 5. The inner surface of the clamping block 74 is provided with anti-slip texture, and its curvature is adapted to the outer curvature of the bite 4.

[0031] In one embodiment of the present invention, a rotating ring 75 is rotatably connected to the inside of a cavity 71, coaxially arranged with the cavity 71, and freely circumferentially rotatable. Arc-shaped blocks 76 are fixedly connected to the side of the rotating ring 75 near the center of the mounting base 5, the number of which is the same as the top block 73 and evenly distributed circumferentially along the rotating ring 75. The arc-shaped surface of the arc-shaped blocks 76 is adapted to the arc-shaped end of the top block 73. A connecting groove 77 is formed on the inner wall of the top of the cavity 71 and communicates with the first sliding groove 66. A connecting block 78 is fixedly connected to the top of the rotating ring 75 and one side of the first slider 67, and slidably connected inside the connecting groove 77, used to realize the linkage between the first slider 67 and the rotating ring 75, driving the rotating ring 75 to rotate synchronously. The second sliding groove 76... 9 is located on the bottom inner wall of cavity 71 and below top block 73, and the number is the same as that of top block 73. The second slider 710 is fixedly connected to the bottom of top block 73 and slidably connected to the second slide groove 79. Its shape matches the second slide groove 79. The second spring 711 is installed inside the second slide groove 79 and its two ends are respectively fixedly connected to the inner wall of the second slider 710 near the center of the mounting base 5 and the second slide groove 79 near the center of the mounting base 5. In the natural state, the top block 73 is pulled into the cavity 71 to retract. The elastic force of the first spring 68 is greater than the sum of the elastic forces of all the second springs 711, ensuring that the first spring 68 can push the top block 73 to move towards the center of the mounting base 5 when it rebounds.

[0032] During operation, when the first slider 67 slides along the first groove 66 to compress the first spring 68, the connecting block 78 will drive the rotating ring 75 and the arc-shaped block 76 to move synchronously with the first slider 67 in the cavity 71. When the arc-shaped block 76 moves away from the back of the top block 73, the second spring 711 rebounds and drives the top block 73 and the clamping block 74 to move into the cavity 71 through the second slider 710. When the first spring 68 rebounds, the first slider 67 drives the rotating ring 75 and the arc-shaped block 76 to move in the opposite direction through the connecting block 78. When the arc-shaped block 76 contacts the top block 73, since the elastic force of the first spring 68 is greater than the sum of the elastic forces of all the second springs 711, the arc-shaped block 76 will push the top block 73 toward the center of the mounting base 5 and compress the second spring 711 through the second slider 710.

[0033] Working principle: First, the first slider 67 slides along the first groove 66 to compress the first spring 68. During this process, the connecting rod 69 drives the piston 64 to move synchronously with the first slider 67 in the air chamber 63 and draws air from the sealing ring 62 into the air chamber 63 through the connecting hole 65, thus reducing its size. At the same time, the connecting block 78 drives the rotating ring 75 and the arc-shaped block 76 to move synchronously with the first slider 67 in the cavity 71. When the arc-shaped block 76 moves away from the back of the top block 73, the second spring 711 rebounds and drives the top block 73 and the clamping block 74 to move into the cavity 71 through the second slider 710. When the sealing ring 62 shrinks to the point of being submerged in the mounting groove 61 and the clamping block 74 is tightly fitted against the inner wall of the mounting base 5, the bottom of the mouthpiece 4 is placed around the outer periphery of the breathing channel 3. Then, the first slider 67 is released, the first spring 68 rebounds and drives the rotating ring 75 and the arc-shaped block 76 to move in the opposite direction through the first slider 67. When the arc-shaped block 76 and the top block 73... Upon contact, since the elastic force of the first spring 68 is greater than the sum of the elastic forces of all the second springs 711, the arc-shaped block 76 will push the top block 73 toward the center of the mounting base 5 and squeeze the second spring 711 through the second slider 710. When the clamping block 74 moves with the top block 73 to fit tightly against the mouthpiece 4, it can be fixed on the outside of the breathing channel 3. At the same time, the connecting rod 69 will drive the piston 64 to move in the opposite direction with the first slider 67 and send the air in the air chamber 63 to the sealing ring 62 through the connecting hole 65 to make it expand. When the sealing ring 62 expands to fit tightly against the mouthpiece 4 and the breathing channel 3, it can seal the mouthpiece 4 and the breathing channel 3. Then breathing training can begin. After the training is completed, slide the first slider 67 along the first slide groove 66 again to squeeze the first spring 68. At this time, the sealing ring 62 gradually shrinks, and the clamping block 74 moves away from the outer periphery of the mouthpiece 4. Then the mouthpiece 4 can be removed for cleaning.
