Description

Technical Field

[0001] This application belongs to the technical field of respiratory training equipment, and specifically relates to a respiratory training device for pulmonary rehabilitation. Background Technique

[0002] The lungs are the respiratory organs of the human body, located in the chest cavity, one on each side, covering the heart. After the treatment of lung diseases, most patients need to undergo respiratory training after recovery. Respiratory training refers to ensuring the patency of the respiratory tract and improving the function of the respiratory muscles. The respiratory muscles do not directly act on the lungs and bronchi, but change the volume of the thoracic cavity, causing corresponding changes in the intrathoracic pressure, thereby causing the alveoli to expand and retract, driving the gas to enter and exit.

[0003] Referring to CN 220125455 U, a rehabilitation pulmonary respiratory training device, which relates to the technical field of pulmonary rehabilitation exercise. The rehabilitation pulmonary respiratory training device includes: an air inlet and outlet pipe that is hollow and has openings at both ends, and one end opening of the air inlet and outlet pipe is connected with a connection ring; wherein, the other end opening inside of the air inlet and outlet pipe is rotatably connected with a closing plate through a pin shaft, a bayonet is opened on the side of the closing plate away from the pin shaft, and a sealing block matched with the bayonet is arranged on the inner wall of the air inlet and outlet pipe. In this rehabilitation pulmonary respiratory training device, the closing plate is elastically connected inside the air inlet and outlet pipe. During breathing, it is necessary to overcome the elastic force of the reset elastic member by the force of the lungs to push the closing plate to rotate, so that the inside of the air inlet and outlet pipe is unblocked, the respiratory gas flows, promoting the training of the lungs and thoracic muscles, and it can intake and exhaust air, enabling the exercise of the lungs to be carried out continuously.

[0004] However, there are still the following problems. The lung capacity of each person is different, and this device cannot adjust the resistance during exhalation. As a result, patients with a large lung capacity are too easy to exhale and fail to achieve the training effect, while patients with a small lung capacity will have difficulty blowing, with poor applicability and inconvenience in use. Utility Model Content

[0005] The purpose of this application is to provide a respiratory training device for pulmonary rehabilitation to solve the above-mentioned problems that the lung capacity of each person is different, this device cannot adjust the resistance during exhalation, resulting in patients with a large lung capacity being too easy to exhale and failing to achieve the training effect, while patients with a small lung capacity will have difficulty blowing, with poor applicability and inconvenience in use.

[0006] The technical solution adopted in this application is as follows: A breathing training device for pulmonary rehabilitation, including a sealed box body and a handle. An air inlet hole is provided on the upper surface of the sealed box body, and an air inlet pipe is fixedly connected to the inner wall of the air inlet hole. A top plate is arranged on the inner wall of the handle, and a pressing plate is slidably connected to the inner wall of the handle.

[0007] By adopting the above technical solution, first, rotate the circular plate according to the vital capacity of each person. When a patient with a larger vital capacity is training, first rotate the circular plate. The rotation of the circular plate drives the rotation of the threaded push rod. The rotation of the threaded push rod pushes the pressing plate to move. The pressing plate moves upward, and the spring is slowly compressed. As the pressing plate continues to move upward, the spring is compressed tighter. At this time, the resistance during blowing becomes larger. When a patient with a smaller vital capacity is training, rotate the circular plate in the reverse direction. The rotation of the circular plate drives the rotation of the threaded push rod. The reverse rotation of the threaded push rod drives the pressing plate to move downward by using the threaded cylinder. At this time, the spring becomes loose and the resistance to the top plate becomes smaller, making it easier to blow. After adjustment, hold the blowing nozzle and blow. At this time, the top plate moves downward, and the gas below the air outlet pipe is exhaled from the air outlet pipe. Then use more force to blow to maintain the top plate, achieving the training effect. Thus, the device has the effect of adjusting the required force for blowing and is suitable for different people to use.

[0023] 1. In the present application, first, the round plate is rotated according to the vital capacity of each person. When a patient with a larger vital capacity trains and uses it, the round plate is rotated first. The rotation of the round plate drives the threaded push rod to rotate. The rotation of the threaded push rod pushes the pressing plate to move. The pressing plate moves upward, and the spring is slowly compressed. As the pressing plate continues to move upward, the spring is compressed tighter. At this time, the resistance received during blowing becomes larger. When a patient with a smaller vital capacity trains and uses it, the round plate is rotated in the reverse direction. The rotation of the round plate drives the threaded push rod to rotate. The reverse rotation of the threaded push rod drives the pressing plate to move downward by using the threaded cylinder. At this time, the spring becomes loose and the resistance to the top plate becomes smaller, making it easier to blow air. After the adjustment is completed, hold the blowing nozzle and blow air.

[0040] The implementation principle of the embodiment of a respiratory training device for pulmonary rehabilitation in this application is as follows: First, rotate the circular plate 6 according to the vital capacity of each person. When a patient with a larger vital capacity trains and uses it, first rotate the circular plate 6. The rotation of the circular plate 6 drives the threaded push rod 8 to rotate. The rotation of the threaded push rod 8 pushes the pressing plate 18 to move. The pressing plate 18 moves upward, and the spring 15 is slowly compressed. As the pressing plate 18 moves upward continuously, the spring 15 is compressed tighter. At this time, the resistance during blowing becomes larger. When a patient with a smaller vital capacity trains and uses it, rotate the circular plate 6 in the reverse direction. The rotation of the circular plate 6 drives the threaded push rod 8 to rotate. The reverse rotation of the threaded push rod 8 drives the pressing plate 18 to move downward by using the threaded cylinder 21. At this time, the spring 15 becomes loose and the resistance to the top plate 12 becomes smaller, making it easier to blow air. After adjustment, hold the blowing nozzle 4 and blow air. At this time, the top plate 12 moves downward. When the gas reaches below the air outlet pipe 5, the gas is exhaled from the air outlet pipe 5. Then use more force to blow air to maintain the top plate 12, achieving the training effect. Thus, the device has the effect of adjusting the required force for blowing air and is suitable for different groups of people to use.
