Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a home rehabilitation device for COPD based on respiratory efficiency feedback. Background Technology
[0002] COPD is a common chronic disease characterized by airflow obstruction, which is a form of chronic bronchitis or emphysema that can further develop into pulmonary heart disease and respiratory failure. In addition to hospital treatment, home rehabilitation training is also essential for the treatment and rehabilitation of COPD. Home rehabilitation devices for COPD can be conveniently carried by patients at home or when they go out to carry out rehabilitation training anytime and anywhere.
[0003] In the prior art, Chinese patent document CN223311610U discloses a breathing device for COPD rehabilitation training, including a nozzle, an air cylinder with a built-in filter, and a cylinder cap with an opening. Its key feature is that it further includes an active pressure regulation component and a control component. The active pressure regulation component includes an adjustment cylinder, a forward and reverse motor, a support, and fan blades. The nozzle, air cylinder, adjustment cylinder, and cylinder cap are sequentially and sealed together. It has a compact structure, is easy to carry, and uses an electronically controlled active pressure regulation component to dynamically adjust the resistance of breathing training in real time, allowing users to find a more comfortable resistance level more quickly during training. A built-in pressure sensor monitors the internal pressure value of the device in real time. If the breathing training exceeds the airway's tolerance pressure, the active pressure regulation component immediately reduces the pressure, making rehabilitation training safer.
[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing COPD home rehabilitation devices are mostly integrated devices, and patients can view their breathing through a screen or connected mobile device after a certain period of time. For some patients with low levels of education, the operation is difficult and the feedback on breathing efficiency is not direct, which makes it impossible for patients to judge their training and rehabilitation status in time, resulting in a poor overall user experience. Summary of the Invention
[0005] The technical problem to be solved by this invention is that the existing technology has the disadvantage of not providing direct feedback on respiratory efficiency for patients with low levels of education. To address this, we propose a home rehabilitation device for COPD based on respiratory efficiency feedback.
[0006] To achieve the above objectives, this application adopts the following technical solution: a COPD home rehabilitation device based on respiratory efficiency feedback, comprising a respiratory training and rehabilitation device body, an extension tube provided at the front end of the respiratory training and rehabilitation device body, a breathing mask fixedly connected to the end of the extension tube away from the respiratory training and rehabilitation device body, a feedback component provided in the middle of the extension tube, an adjustment component provided inside the feedback component, a supplementary component provided on the side of the feedback component, and a protective component provided on the side of the respiratory training and rehabilitation device body.

[0008] Preferably, a lead screw is threaded through the middle of the base, a cylinder is fixedly connected to the top of the lead screw, a frustum is fixedly connected to the top of the cylinder, and a knob is fixedly connected to the bottom of the lead screw.
[0009] Preferably, the friction plates are arranged in annular staggered pattern, one end of the friction plate extending into the cylinder is fixedly connected to a side plate, a spring is fixedly connected to the outer surface of the side plate, and the end of the spring away from the side plate is fixedly connected to the inner wall of the cylinder.
[0010] Preferably, the supplementary component includes an ear plate fixedly connected to the side of the hollow box, a shaft fixedly connected to the inner wall of the ear plate, a swing rod movably sleeved on the outer surface of the shaft, and one end of the swing rod extending into the hollow box being engaged in the gap of the airflow blades.
[0011] Preferably, a striking rod is fixedly connected to one end of the swing rod that extends into the ear plate, and a sound-generating block is fixedly connected to the inner wall of the ear plate.

In this invention, by setting up protective components on the outside of the device, the respirator is wrapped and protected by a protective cover, which reduces the contamination of the respirator and makes it convenient for patients to carry it out and store it after use at home.

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.
[0020] Reference Figures 1 to 7 As shown, the present invention provides a technical solution: a home rehabilitation device for COPD based on respiratory efficiency feedback, including a respiratory training and rehabilitation device body 1, an extension tube 2 at the front end of the respiratory training and rehabilitation device body 1, a breathing mask 3 fixedly connected to the end of the extension tube 2 away from the respiratory training and rehabilitation device body 1, a feedback component 4 in the middle of the extension tube 2, an adjustment component 5 inside the feedback component 4, a supplementary component 6 on the side of the feedback component 4, and a protective component 7 on the side of the respiratory training and rehabilitation device body 1.
[0021] When performing breathing training, the patient aligns the breathing mask 3 with their mouth and nose and completely covers it. After activating the device, the patient can perform breathing training according to their own situation. During the breathing process, the feedback component 4 can be used to view the breathing efficiency and changes in real time. The supplementary component 6 provides two-way supplementary feedback of sound and vision to enhance the feedback effect. The adjustment component 5 can be used to change the breathing damping, which can be adjusted according to the patient's training situation. The protective component 7 can protect the breathing mask 3, making it convenient for the patient to carry and store.
[0022] Reference Figures 2 to 4As shown, the feedback component 4 includes a hollow box 41 fixedly connected to the middle of the extension tube 2. A central shaft 42 is movably inserted into the upper part of the hollow box 41. Airflow blades 43 are distributed in a ring array on the outer surface of the central shaft 42. A rope 44 is fixedly connected to the upper part of the outer surface of two adjacent airflow blades 43. A red cloth 45 is fixedly wrapped around the middle of the outer surface of the rope 44. A one-way bearing 46 is sleeved on the upper part of the outer surface of the central shaft 42. The one-way bearing 46 is rotatably connected to the upper part of the hollow box 41. Two one-way bearings 46 are symmetrically distributed on the central shaft 42 and the one-way bearings 46 on the outer surface of the two central shafts 42 can rotate in opposite directions. The upper surface of the hollow box 41 is a transparent structure.
[0023] The airflow generated by the patient's breathing drives the airflow blades 43 to rotate. As the airflow blades 43 rotate around the central axis 42, the red cloth 45 moves in a circular motion. The trajectory of the red cloth 45 can be clearly seen through the transparent top shell of the hollow box 41. Furthermore, the rotation rate of the red cloth 45 changes with the patient's breathing rate, allowing the patient to clearly see the feedback on breathing efficiency during breathing. In addition, the central axes 42 on both sides of the hollow box 41 are rotatably connected to the hollow box 41 through one-way bearings 46, and their rotational directions are opposite. This allows for separate feedback for exhalation and inhalation, resulting in a more detailed feedback effect.
[0024] Reference Figure 2 , Figure 3 and Figure 6 As shown, the supplementary component 6 includes an ear plate 61 fixedly connected to the side of the hollow box 41. A shaft 62 is fixedly connected to the inner wall of the ear plate 61. A swing rod 63 is movably sleeved on the outer surface of the shaft 62. One end of the swing rod 63 extends into the hollow box 41 and is inserted into the gap of the airflow blade 43. A striking rod 64 is fixedly connected to the other end of the swing rod 63 extending into the ear plate 61. A sound-generating block 65 is fixedly connected to the inner wall of the ear plate 61. A torsion spring 66 is sleeved on the outer surface of the shaft 62. The top end of the torsion spring 66 is fixedly connected to the swing rod 63, and the bottom end is fixedly connected to the inner wall of the ear plate 61.
[0025] During the rotation of the airflow blade 43, it will actuate the swing arm 63. The swing arm 63 rotates around the shaft 62 and compresses the torsion spring 66. After the current airflow blade 43 passes the swing arm 63, the torsion spring 66 rebounds and drives the swing arm 63 to rotate in the opposite direction. Then, under the action of inertia, the striking rod 64 at the end of the swing arm 63 away from the airflow blade 43 will collide with the sound-generating block 65. In this way, under the action of the reciprocating rotating airflow blade 43, a continuous collision can be generated, thus achieving the purpose of supplementary sound feedback. This complements the visual feedback and further improves the feedback effect.
[0026] Reference Figures 3 to 5As shown, the adjustment assembly 5 includes a base 51 fixedly connected to the bottom of the hollow box 41. A cylinder 52 is fixedly connected to the upper surface of the base 51. Friction plates 56 are slidably connected to the inner wall of the cylinder 52. A lead screw 53 is threaded through the middle of the base 51. A cylinder 54 is fixedly connected to the top of the lead screw 53. A frustum 55 is fixedly connected to the top of the cylinder 54. A knob 59 is fixedly connected to the bottom of the lead screw 53. The friction plates 56 are distributed in an alternating ring pattern. A side plate 57 is fixedly connected to one end of the friction plate 56 that extends into the cylinder 52. A spring 58 is fixedly connected to the outer surface of the side plate 57. The end of the spring 58 away from the side plate 57 is fixedly connected to the inner wall of the cylinder 52.
[0027] Rotating knob 59 drives lead screw 53 to rotate. Inside base 51, lead screw 53 rotates and moves vertically up and down under the guidance of the thread. When lead screw 53 moves upward, frustum 55 contacts side plate 57 and gradually pushes friction plate 56 closer to the inner wall of central shaft 42, compressing spring 58. After cylinder 54 contacts side plate 57, friction plate 56 just abuts against the inner wall of central shaft 42. Since friction plate 56 is distributed in a ring and staggered manner, the number of active friction plates 56 can be controlled by controlling the moving distance of lead screw 53, thereby adjusting the damping of central shaft 42 rotation. Moving lead screw 53 upward increases damping, and moving lead screw 53 downward decreases damping. Patients can adjust it themselves according to their own exercise conditions, improving the adaptability of the device.
[0028] Reference Figure 2 and Figure 7 As shown, the protective component 7 includes elastic ropes 71 disposed on both sides of the breathing training and rehabilitation device body 1. A protective cover 72 is fixedly connected to the end of the elastic rope 71 away from the breathing training and rehabilitation device body 1. The protective cover 72 is fitted over the outside of the breathing mask 3. A restraining cloth 73 is fixedly connected to the end of the protective cover 72. An elastic cord 74 is fixedly connected to the inner circle of the restraining cloth 73. An installation cylinder 75 is fixedly connected to the side of the breathing training and rehabilitation device body 1. An elastic ring 76 is fixedly connected to the end of the elastic rope 71. The elastic ring 76 is snapped into the inside of the installation cylinder 75.
[0029] After pulling the elastic rope 71 to an appropriate distance, fasten the protective cover 72 to the outside of the breathing mask 3. The elastic rope 74 at the end of the protective cover 72 retracts and binds to the outside of the breathing mask 3. Together with the binding cloth 73, the breathing mask 3 is wrapped to reduce the contamination of the breathing mask 3. When it is needed, the protective cover 72 can be removed. The protective cover 72 can be disassembled and cleaned by forcefully pulling out the elastic ring 76 inside the mounting cylinder 75.
[0030] Working principle: When the patient is performing breathing training, they place the breathing mask 3 over their mouth and nose and completely cover it. After activating the device, the patient can perform breathing training according to their own situation. A feedback component 4 is set in the middle of the extension tube 2. The airflow generated by the patient's inhalation and exhalation will drive the feedback component 4 to operate. The specific operation process is as follows: the airflow generated by the patient's breathing will drive the airflow blades 43 to rotate. The upper part of every two airflow blades 43 is connected by a rope 44, and the rope 44 is wrapped with a red cloth 45. The airflow blades 43 rotate around the center. During the rotation of shaft 42, the red cloth 45 moves in a circular motion. The trajectory of the red cloth 45 can be clearly seen through the transparent top shell of the hollow box 41. As the patient's breathing rate changes, the rotation rate of the red cloth 45 also changes. The patient can clearly see the feedback on breathing efficiency during breathing. In addition, the central shafts 42 on both sides inside the hollow box 41 are rotatably connected to the hollow box 41 through one-way bearings 46, and the two can rotate in opposite directions. This allows for separate feedback of exhalation and inhalation, resulting in a more detailed feedback effect. During the rotation of the airflow blade 43, the swing arm 63 is actuated, which pushes the swing arm 63 to rotate around the shaft 62 and compress the torsion spring 66 to store elastic potential energy. After the current airflow blade 43 passes the swing arm 63, the torsion spring 66 rebounds and drives the swing arm 63 to rotate in the opposite direction. Then, under the action of inertia, the striking rod 64 at the end of the swing arm 63 away from the airflow blade 43 will collide with the sound-generating block 65. In this way, under the action of the reciprocating rotating airflow blade 43, a continuous collision can be generated, thus achieving the purpose of supplementary sound feedback, which complements the visual feedback and further improves the feedback effect. After the patient's breathing intensity increases following training, the patient can simultaneously adjust the feedback damping. By rotating knob 59, the lead screw 53 can be rotated. The lead screw 53 rotates inside the base 51 and moves vertically up and down under the guidance of the thread, which in turn causes the cylinder 54 and the frustum 55 at the top of the lead screw 53 to move synchronously. When the lead screw 53 moves upward, the frustum 55 contacts the side plate 57 and gradually pushes the friction plate 56 closer to the inner wall of the central shaft 42 and squeezes the spring 58. After the cylinder 54 contacts the side plate 57, the friction plate 56 just abuts against the inner wall of the central shaft 42. Since the friction plate 56 is distributed in a ring and staggered manner, the number of active friction plates 56 can be controlled by controlling the moving distance of the lead screw 53, thereby adjusting the damping of the rotation of the central shaft 42. Moving the lead screw 53 upward increases the damping, and moving the lead screw 53 downward decreases the damping. The patient can adjust it according to their own training situation, which improves the adaptability of the device. Patients can train at home or while taking the device out, depending on their needs. A protective component 7 is installed on the outside of the main body 1 of the breathing training rehabilitation device. After taking the device out or using it at home, the patient can pull the elastic rope 71 to an appropriate distance and then fasten the protective cover 72 to the outside of the breathing mask 3. The elastic rope 74 at the end of the protective cover 72 will contract and bind the outside of the breathing mask 3. Together with the binding cloth 73, the breathing mask 3 is wrapped to reduce the contamination of the breathing mask 3. The protective cover 72 can be removed when needed. In addition, the patient can disassemble the protective cover 72 for cleaning according to the usage time. Simply pull out the elastic ring 76 in the mounting cylinder 75. The same applies after cleaning. Press the elastic ring 76 into the mounting cylinder 75 to complete the connection between the protective cover 72 and the main body 1 of the breathing training rehabilitation device.
[0031] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
