Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a multifunctional COPD rehabilitation training device and its training method. Background Technology

[0002] COPD, short for Chronic Obstructive Pulmonary Disease, is a disease characterized by airflow limitation and is preventable and treatable. The cause of COPD is likely the result of a long-term interaction between various environmental and bodily factors. Patients with COPD experience symptoms such as persistent cough, sputum production, wheezing, shortness of breath, and difficulty breathing. After being diagnosed with COPD, rehabilitation training is necessary to restore lung function. Currently, the most commonly used rehabilitation training methods are respiratory function training and physical fitness training. Additionally, because patients with COPD may experience weakness in the limbs and weight loss, timely nutritional support is also required, such as a diet high in fat, protein, and energy.

[0003] Respiratory function training strengthens respiratory muscles and improves lung ventilation through exercises such as diaphragmatic breathing, pursed-lip breathing, and nasal ventilation. Currently, COPD rehabilitation training devices are commonly used to assist patients with respiratory function training; however, some devices have the following drawbacks:

[0004] 1. If a patient needs to rest briefly or resume normal breathing during respiratory function training using the device, the device must be removed before normal ventilation can resume. The patient will need to put the device back on for training again, which is inconvenient.

[0005] 2. When using the device for training, patients cannot intuitively understand their expiratory and inspiratory intensities, nor can they easily adjust their breathing rate according to their specific breathing conditions, which in turn makes it difficult to adjust their training intensity.

[0006] 3. Some existing devices do not have the function of adjusting the training intensity of patients. Some patients with better recovery have a larger breathing range, and using the initial breathing training intensity cannot achieve good training results, which is not conducive to the rehabilitation of COPD. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the above-mentioned technology by providing a multifunctional COPD rehabilitation training device and its training method. During the training process, the patient does not need to remove the breathing mask, and normal ventilation can be quickly restored. Furthermore, the training intensity can be displayed more intuitively by controlling the pointer to swing with each breath of the patient, making it convenient for the patient to adjust the training intensity. At the same time, it can facilitate patients with different recovery levels to carry out training of different intensities, making it more convenient and practical to use.

[0011] In a preferred embodiment of the present invention, a metering component is further included.

[0012] In a preferred embodiment of the present invention, a training resistance component is further included. The training resistance component is disposed on the first guide frame. The training resistance component includes a push frame, a support rod, a swing frame, a first torsion spring, a friction frame, a second torsion spring, and a friction ring.

[0013] In a preferred embodiment of the present invention, a resistance increasing component is further included. The resistance increasing component is disposed on the guide tube and includes a squeezing frame and a baffle frame. The squeezing frame is fixedly connected to the bottom of the inner wall of the guide tube, and the baffle frame is slidably connected to the vent plate. The baffle frame is located below the vent hole of the vent plate, and the baffle frame is slidably connected to the squeezing frame.

[0014] In a preferred embodiment of the present invention, a sponge pad is further included, which is fixedly connected to the breathing mask.

[0015] In a preferred embodiment of the present invention, a training method for a multifunctional COPD rehabilitation training device includes the following steps:

[0016] Step 1: First, put the breathing mask over your mouth and nose, then breathe slowly;

[0017] Step 2: During inhalation, the partition frame moves closer to the connecting hose and no longer blocks the clogging ring, allowing outside air to enter the breathing mask. At the same time, the metering disc reverses, causing the turbine frame to reverse, making the pointer swing in the opposite direction and change the value on the scale. If the inhalation intensity is high, the friction frame swings upward and locks the friction ring, thereby increasing the inhalation resistance.

[0018] Step 3: During exhalation, the ventilation plate moves and blocks the separator ring, allowing gas to pass slowly through the ventilation holes of the ventilation plate, so as to exhale slowly. At the same time, the metering disc rotates, driving the worm gear to rotate, causing the pointer to swing and change the scale value on the dial. If the exhalation intensity is high, the friction frame swings downward and locks the friction ring, thereby increasing the exhalation resistance.

[0019] Step 4: When you need to breathe normally, press the support frame to connect the air outlet of the duct to the outside air, and then you can breathe normally through the air outlet of the duct.

[0020] Step 5: Once the training is complete, simply remove the breathing mask and elastic band.

[0021] Beneficial effects: In this invention, firstly, when the patient inhales, a negative pressure is created in the drainage tube, causing the partition frame to move and no longer block the obstruction ring, allowing the patient to inhale oxygen. The return spring increases the resistance to the patient's inhalation, thereby training the patient's oxygen intake capacity and assisting in lung function training. When the patient exhales, the air pressure in the drainage tube increases, causing the ventilation plate to move and block the partition ring. The gas in the drainage tube can only slowly pass through the ventilation holes of the ventilation plate, allowing the patient to exhale slowly. By allowing the patient to exhale and inhale slowly, while increasing the respiratory resistance, the respiratory muscles are trained, cardiopulmonary endurance is improved, and the patient's lung ventilation function is improved, which is beneficial to the recovery of COPD. At the same time, when the patient needs to breathe normally, there is no need to remove the breathing mask. Simply press down on the support frame to connect the outlet tube of the drainage tube to the outside air, and then the patient can breathe normally through the outlet tube of the drainage tube, allowing the lungs and respiratory muscles to relax. It is convenient to use.

[0022] Secondly, when the patient exhales, the exhaled air pushes the measuring disc to rotate, the spiral spring is unwound, and the pointer swings. The pointer swings and changes the value on the dial, allowing the patient to understand the intensity of exhalation. When the patient inhales, a negative pressure is created within the flow guide frame, causing the measuring disc to reverse. The spiral spring is wound up, causing the pointer to swing in the opposite direction. The pointer swings in the opposite direction and changes the value on the dial, allowing the patient to understand the intensity of inhalation. This makes the training intensity more intuitively displayed, allowing patients to adjust their training intensity according to their recovery progress. At the same time, the elasticity of the spiral spring further increases the resistance to breathing, requiring the patient to use a certain breathing intensity to breathe, thus effectively exercising the patient's respiratory muscles, further improving cardiopulmonary endurance, and promoting COPD rehabilitation.

[0023] Furthermore, if the patient's expiratory intensity is high, the pusher will swing the swing frame downwards, causing the friction frame to swing downwards and increasing the friction between it and the friction ring. This increases the resistance to the rotation of the measuring disc, thus increasing the difficulty of the patient's exhalation. If the patient's inhalation intensity is high, the pusher will swing the swing frame upwards, causing the friction frame to swing upwards and contact the friction ring. This increases the resistance to the reverse rotation of the measuring disc, thus increasing the difficulty of the patient's inhalation. Through the above operations, the training difficulty can be further increased for patients with better recovery and larger breathing amplitudes, making it convenient for patients with different recovery levels to conduct training of different intensities. This makes it more convenient and practical to use. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] Example 1: A multifunctional COPD rehabilitation training device and its training method, such as Figures 1-9As shown, the device includes a first airflow guide frame 1, a connecting tube 2, a second airflow guide frame 3, an airflow guide tube 4, a connecting hose 5, a breathing mask 6, an elastic band 61, a ventilation assembly, and a ventilation assembly. The connecting tube 2 is fixedly connected to the first airflow guide frame 1, and the second airflow guide frame 3 is fixedly connected to the other end of the connecting tube 2. The first airflow guide frame 1 is connected to the second airflow guide frame 3 via the connecting tube 2. The airflow guide tube 4 is fixedly connected to the side of the first airflow guide frame 1 away from the connecting tube 2, and the airflow guide tube 4 is connected to the first airflow guide frame 1. An air outlet pipe is provided on the guide tube 4. The connecting hose 5 is fixedly connected to the end of the guide tube 4 away from the guide frame 1, and the connecting hose 5 is in communication with the guide tube 4. The connecting hose 5 is made of soft material. The breathing mask 6 is fixedly connected to the end of the connecting hose 5 away from the guide tube 4, and the breathing mask 6 is in communication with the connecting hose 5. The elastic band 61 is fixedly connected to the breathing mask 6. The ventilation component is provided on the guide tube 4, and the air exchange component is provided on the guide tube 4.

[0036] The ventilation assembly includes a blocking ring 71, a partition frame 72, a return spring 721, a ventilation plate 73, and a separating ring 74. The blocking ring 71 is bolted to the inner wall of the guide pipe 4. The partition frame 72 is slidably connected to the blocking ring 71. A return spring 721 is connected between the blocking ring 71 and the partition frame 72. The ventilation plate 73 is bolted to the end of the partition frame 72 near the guide frame 1. The ventilation plate 73 has ventilation holes. The separating ring 74 is bolted to the inner wall of the guide pipe 4.

[0037] The ventilation assembly includes a support spring 81, a support frame 82, and a rubber plate 83. The support spring 81 is embedded in the air outlet of the guide pipe 4. The support frame 82 is fixedly connected to the other end of the support spring 81 and passes through the air outlet of the guide pipe 4. The rubber plate 83 is fixedly connected to the lower end of the support frame 82 and contacts the inner wall of the guide pipe 4. The rubber plate 83 is used to block the air outlet of the guide pipe 4.

[0038] In practical application, the patient first puts the breathing mask 6 on the mouth and nose area through the elastic band 61, and then breathes in and out rhythmically. Because the partition frame 72 blocks the blocking ring 71, when the patient inhales, a negative pressure is formed inside the guide tube 4 and connecting hose 5. This causes the partition frame 72 and ventilation plate 73 to move towards the side closer to the connecting hose 5 under the action of negative pressure. The return spring 721 is compressed, and the movement of the partition frame 72 will no longer block the blocking ring 71. Outside air will flow through the connecting tube 2 and the second guide frame 3 into the first guide frame 1, and then through the guide tube 4 and the connecting hose 5 into the breathing mask 6, so that... When the patient inhales oxygen, the elasticity of the return spring 721 increases resistance to the patient's inhalation, thus helping to train the patient's oxygen intake capacity and assisting in lung function training. As the pressure in the drainage tube 4 and connecting hose 5 returns to equilibrium, the return spring 721 resets, causing the partition frame 72 and ventilation plate 73 to reset as well. The reset of the partition frame 72 will again block the obstruction ring 71. When the patient exhales, the air pressure in the drainage tube 4 and connecting hose 5 increases, causing the partition frame 72 and ventilation plate 73 to move away from the connecting hose 5 under the action of air pressure. The return spring 721 is stretched, and the movement of the partition frame 72 will no longer block the obstruction ring 71. When the blocking ring 71 is closed, the ventilation plate 73 moves and contacts the separating ring 74, blocking the separating ring 74. This allows the air in the guide tube 4 and connecting hose 5 to slowly pass through the ventilation holes of the ventilation plate 73, thus enabling the patient to exhale slowly. This strengthens the respiratory muscles. By repeating this process, the patient is allowed to exhale and inhale slowly, while increasing the respiratory resistance, which exercises the respiratory muscles, improves cardiopulmonary endurance, and improves the patient's lung ventilation function. This is beneficial for the recovery of COPD. When the patient needs to breathe normally, there is no need to remove the breathing mask 6; simply press down on the support frame 82 to support the breathing. When spring 81 is compressed, rubber plate 83 moves downward and no longer blocks the outlet of the duct 4, allowing the outlet of the duct 4 to connect with the outside air. At this time, the patient can breathe normally through the outlet of the duct 4, relaxing the lungs and respiratory muscles. It is convenient to use. After the patient has rested, the support frame 82 is released, and the return of support spring 81 will cause the support frame 82 and rubber plate 83 to return upward. The return of rubber plate 83 will block the outlet of the duct 4 again, cutting off the connection between the duct 4 and the outside air, so that the patient can carry out rehabilitation training. After the patient has completed the training, he / she only needs to remove the breathing mask 6 and elastic band 61.

[0039] Example 2: Based on Example 1, such as Figures 1-9As shown, it also includes a metering component, which is mounted on the guide frame 1. The metering component includes a metering disk 91, a support base 92, a worm gear 93, a turbine frame 94, a pointer 95, a scale 96, and a spiral spring 97. The metering disk 91 is rotatably connected to the guide frame 1 and is located inside the guide frame 1. The support base 92 is bolted to one side of the outer wall of the guide frame 1. The worm gear 93 is bolted to the metering disk 91 located on the guide frame 1. On the outer side of 1, the turbine frame 94 is rotatably connected to the support base 92, the worm gear 93 meshes with the turbine frame 94, the pointer 95 is bolted to the top of the turbine frame 94, the dial 96 is bolted to the support base 92, the turbine frame 94 passes through the dial 96, the pointer 95 is located above the dial 96, the dial 96 has a scale on the top, and a spiral spring 97 is connected between the side of the metering disk 91 away from the worm gear 93 and the guide frame 1.

[0040] Initially, pointer 95 points to a reading of 0 on dial 96. When the patient exhales, the air pressure within the flow guide frame 1 increases. Simultaneously, the exhaled air pushes the measuring disc 91 to rotate, unwinding the spiral spring 97. The rotation of the measuring disc 91 drives the worm gear 93, which in turn drives the turbine frame 94. The rotation of the turbine frame 94 causes pointer 95 to swing, changing the reading on dial 96. The patient can then determine their health status by observing the reading indicated by pointer 95. The intensity of exhalation is controlled. When the patient stops exhaling, the spiral spring 97 rebounds, causing the measuring disc 91 to reverse. The reverse rotation of the measuring disc 91 causes the worm gear 93 to reverse, which in turn causes the turbine frame 94 to reverse. The reverse rotation of the turbine frame 94 causes the pointer 95 to swing in the opposite direction, causing the scale value of the dial 96 pointed to by the pointer 95 to return to 0. When the patient inhales, a negative pressure is created in the flow guide frame 1. The air pressure in the flow guide frame 1 causes the measuring disc 91 to reverse, the spiral spring 97 is wound up, and the measuring disc 91 reverses... The rotation of the worm gear 93 causes it to reverse, which in turn causes the turbine frame 94 to reverse. The reverse rotation of the turbine frame 94 causes the pointer 95 to swing in the opposite direction. The reverse swing of the pointer 95 changes the value indicated on the scale 96. The patient can understand the intensity of inhalation by checking the value indicated by the pointer 95. When the patient stops inhaling, the spiral spring 97 rebounds, causing the measuring disc 91 to rotate. The rotation of the measuring disc 91 causes the worm gear 93 to rotate, which in turn causes the turbine frame 94 to rotate. The rotation of the turbine frame 94 causes the pointer 95 to swing, causing the value indicated by the pointer 95 on the scale 96 to return to 0. This process repeats, thus making the patient's training intensity more intuitive and allowing the patient to adjust their training intensity according to their recovery. At the same time, the elasticity of the spiral spring 97 further increases the resistance to the patient's breathing, requiring the patient to use a certain breathing intensity to breathe, thereby effectively exercising the patient's respiratory muscles, further improving cardiopulmonary endurance, and being more conducive to the rehabilitation of COPD.

[0041] Example 3: Based on Example 2, such as Figures 3-9As shown, it also includes a training resistance assembly, which is mounted on the guide frame 1. The training resistance assembly includes a push frame 101, a support rod 102, a swing frame 103, a torsion spring 1031, a friction frame 104, a torsion spring 105, and a friction ring 106. The push frame 101 is bolted to the bottom of the turbine frame 94. The support rod 102 is fixedly connected to the outer wall of the guide frame 1 near the support base 92 and is horizontally positioned. The swing frame 103 is rotatably connected to the support rod. On 102, a torsion spring 1031 is connected between the swing frame 103 and the guide frame 1. The torsion spring 1031 is sleeved on the support rod 102. The friction frame 104 is rotatably connected to the end of the support rod 102 away from the guide frame 1. A torsion spring 105 is connected between the friction frame 104 and the swing frame 103. The torsion spring 105 is sleeved on the support rod 102. The friction ring 106 is fixedly connected to the end of the metering disc 91 near the worm gear 93. The friction ring 106 is located inside the friction frame 104.

[0042] As the measuring disc 91 rotates, it drives the friction ring 106 to rotate. When the patient exhales, the turbine frame 94 rotates, which in turn drives the push frame 101 to swing. If the patient's exhalation is strong, the swinging intensity of the push frame 101 is also strong. At this time, the swinging push frame 101 will contact one side of the swing frame 103, pushing the swing frame 103 to swing downward. The torsion spring 1031 is twisted, and the downward swinging of the swing frame 103 will first drive the friction frame 104 to swing downward through the torsion spring 105. The downward swinging of the friction frame 104 will then contact the friction ring 106. 6. Contact increases the friction between the device and the friction ring 106, thereby increasing the resistance to the rotation of the metering disc 91 and making it more difficult for the patient to exhale. The continued downward swing of the swing frame 103 will cause the second torsion spring 105 to be torsiond. When the turbine frame 94 reverses, it will cause the push frame 101 to swing in the opposite direction. The reverse swing of the push frame 101 will disengage from one side of the swing frame 103. The reset of the first torsion spring 103 will cause the swing frame 103 to reset upwards. At the same time, the reset of the second torsion spring 105 will cause the friction frame 104 to reset upwards and disengage from the friction ring 106. When the patient inhales... This will cause the turbine frame 94 to reverse, which will drive the push frame 101 to swing in the opposite direction. If the patient's inhalation intensity is high, the intensity of the reverse swing of the push frame 101 will also be high. At this time, the reverse swing of the push frame 101 will contact the other side of the swing frame 103 and push the swing frame 103 to swing upward. The torsion spring 1031 will be torsionped in the opposite direction. The upward swing of the swing frame 103 will first drive the friction frame 104 to swing upward through the torsion spring 105. The upward swing of the friction frame 104 will contact the friction ring 106, thereby increasing the resistance to the reverse rotation of the metering disc 91. This increases the difficulty of inhalation for the patient. When the turbine frame 94 rotates, it will drive the push frame 101 to reset. When the push frame 101 resets, it will disengage from one side of the swing frame 103. When the torsion spring 1031 resets, it will drive the swing frame 103 to reset downwards. At the same time, when the torsion spring 105 resets, it will drive the friction frame 104 to reset downwards and disengage from the friction ring 106. This process is repeated to further increase the difficulty of training for patients with better recovery and larger breathing amplitude. This makes it easier for patients with different recovery levels to carry out training of different intensities, making it more convenient and practical to use.

[0043] Example 4: Based on Example 3, such as Figures 4-5 As shown, it also includes a resistance increasing component, which is disposed on the guide pipe 4. The resistance increasing component includes a squeezing frame 111 and a baffle frame 112. The squeezing frame 111 is bolted to the bottom of the inner wall of the guide pipe 4. The baffle frame 112 is slidably connected to the vent plate 73. The baffle frame 112 is located below the vent hole of the vent plate 73. The baffle frame 112 is slidably connected to the squeezing frame 111.

[0044] If the patient's inhalation rate is fast, the ventilation plate 73 will move faster and farther away from the connecting hose 5. As the ventilation plate 73 moves, it will also move the baffle 112. As the baffle 112 moves, it will move upward along the compression frame 111. The upward movement of the baffle 112 will block part of the ventilation hole of the ventilation plate 73, slowing down the outflow of gas and thus reducing the patient's exhalation rate. This will balance the patient's breathing rhythm and keep the patient breathing slowly. When the ventilation plate 73 returns to its original position, it will also move the baffle 112 back to its original position. As the baffle 112 moves, it will move downward along the compression frame 111. The downward repositioning of the baffle 112 will no longer block the ventilation hole of the ventilation plate 73.

[0045] Example 5: Based on Example 4, such as Figure 8 As shown, it also includes a sponge pad 12, which is fixedly connected to the breathing mask 6.

[0046] If the patient wears the breathing mask 6 for a long time, a layer of water mist will appear around the breathing mask 6, and the sponge pad 12 will absorb the water mist between the breathing mask 6 and the patient's face to avoid making the patient feel uncomfortable.

7. The training method of the multifunctional COPD rehabilitation training device according to claim 6, characterized in that, The work includes the following steps: Step 1: First, put the breathing mask (6) on your mouth and nose, and then breathe slowly; Step 2: During inhalation, the partition frame (72) moves closer to the connecting hose (5) and no longer blocks the blocking ring (71), thus allowing outside air to enter the breathing mask (6). At the same time, the metering plate (91) reverses, causing the turbine frame (94) to reverse, causing the pointer (95) to swing in the opposite direction and change the scale value pointing to the dial (96). If the inhalation intensity is high, the friction frame (104) swings upward and locks the friction ring (106), thereby increasing the inhalation resistance.
