Description

Technical Field

[0001] This utility model relates to the field of COPD breathing training technology, specifically a COPD breathing training device. Background Technology

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by airflow obstruction, involving chronic bronchitis and / or emphysema, which can further develop into pulmonary heart disease and respiratory failure. COPD patients require respiratory training devices to improve and restore lung function, and to reduce and prevent postoperative complications.

[0003] Chinese utility model patent CN221932999U discloses a breathing trainer for COPD patients, relating to the field of breathing training technology for COPD patients. The device includes a measuring tube with a mouthpiece at its lower end and a connecting groove at the same end. A guide plate and a limiting ring are fixed to the inner wall of the measuring tube. A lifting rod slides within the measuring tube, and a detection ball is fixed to its lower end. A mounting frame is fixed to the upper surface of the measuring tube, and a rotating shaft is rotatably mounted on the upper end of the frame. A gear is fixed to the outer wall of the rotating shaft, and a pointer is fixed to one end of the shaft. An observation shell is fixed to one side of the mounting frame. In this device, COPD patients blow air through the mouthpiece. The airflow moves the detection ball and the lifting rod upwards. The lifting rod drives the gear to rotate via a toothed groove. The gear drives the rotating shaft, which in turn drives the pointer to rotate synchronously. The amount of air blown is determined by the pointer pointing to a numerical position on the observation shell.

For example, determining the amount of air blown through gear transmission is not accurate enough, and patients need to overcome the gravity of structures such as the detection ball to determine the amount of air blown.

[0024] Please see Figures 1-5 This utility model discloses a COPD breathing trainer, including an air inlet head 1 connected to an air intake adjustment assembly.

One end of the second training shell 6 is threadedly connected to the first training shell 3, and the second air flow detector 7 is mounted on the top of the second training shell 6. It also includes a sealing assembly for sealing the air intake pipe 2.

[0025] Specifically, the sealing component includes a connecting nozzle 8, a filter screen 9 is fixedly connected inside the connecting nozzle 8, and a snap-fit ​​component 10 is fixedly connected to the surface of both the connecting nozzle 8 and the air blowing head 1.

[0027] Specifically, the air intake adjustment structure includes a sealing plate 12 and a threaded rod 13. The threaded rod 13 is movably connected to the sealing plate 12. The sealing plate 12 movably passes through the air intake pipe 2 and is movably connected to the inner wall of the air intake pipe 2. A housing 14 is fixedly connected to the top of the air intake pipe 2. The internal space of the housing 14 is adapted to the size of the sealing plate 12.

[0028] In this embodiment, when the drive motor starts, it can rotate the gear ring 15 through the gear ring 15, thereby rotating the threaded rod 13 through the internal thread, which can then move upward or downward, driving the sealing plate 12 to move, thus adjusting the amount of air passing through the air intake pipe 2, thereby adjusting the air intake resistance.

[0032] In this embodiment, a humidity sensor 22 is located inside the second training shell 6. When the humidity exceeds the standard, the alarm 23 can sound an alarm and stop the use.

[0036] The working principle and usage process of this utility model: During use...

[0037] In summary, this COPD breathing trainer allows COPD patients to exhale through the inhalation head 1, which is snapped onto the air inlet tube 2 via a snap-fit ​​connector 10 for easy disassembly. When the drive motor is activated, it rotates the gear ring 15, which in turn rotates the threaded rod 13 via its internal thread. This allows the rod to move upwards or downwards, moving the sealing plate 12 and thus adjusting the amount of airflow through the air inlet tube 2, thereby regulating the airflow resistance.

[0038] When using the first training component for training, it is easy to carry because the first training component, air inlet pipe 2, and air nozzle 1 are aligned in a straight line, and its small size allows for training outdoors. The airflow rate can be detected by the first airflow detector 4. After training with the first training component is completed, the inside of the first training shell 3 can be disinfected as needed. Activating the infrared sterilizer 20 can heat and disinfect the inside. In addition, to reduce the amount of liquid that may remain inside, the first suction pump 26 is activated to draw in external air into the first training shell 3. The heated air can carry away moisture and be expelled. To prevent excessive external impurities from entering the first training shell 3, the air nozzle 1 is disassembled and a connecting nozzle 8 is installed before suction disinfection. The filter screen 9 inside the connecting nozzle 8 can filter out impurities.

[0039] When using the second training component for training, the first air flow detector 4 needs to be closed to prevent air leakage. This can be done using an electronically controlled valve, for example, by installing an electronically controlled valve at the air inlet of the first air flow detector 4. When not in use, the electronically controlled valve is closed. Then, the screws on the sealing plate 31 are removed to move the sealing plate 31 and open the channel. However, the sealing plate 31 is not detached from the first training part 301 to prevent air leakage. Screw holes for fixing can be provided on the sealing plate 31 to fix the sealing plate 31.

[0040] The second airflow detector 7 can also detect the amount of airflow. Inside the second training shell 6, there is a humidity sensor 22. When the humidity exceeds the standard, the alarm 23 can sound an alarm and stop use. The ultraviolet sterilizer 24 can perform sterilization, and in conjunction with the infrared sterilizer 20, it can enhance the sterilization effect, effectively sterilizing while drying the absorbent cotton 30.
