Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a lung function training device. Background Technology

[0002] The primary purpose of pulmonary function training is to enhance lung function, improve ventilation and gas exchange, especially for pathological lung diseases, and restore normal respiratory function, thereby improving patients' quality of life. Currently, the mainstream method of pulmonary function training is the blowing exercise, such as blowing up balloons to train the lungs' contraction and expansion capabilities. The longer the blowing time and the greater the blowing intensity, the better the patient's lung function. However, while current pulmonary function training devices can record the length of blowing time, they cannot reflect the blowing intensity, making the evaluation of the training effect incomplete and preventing patients from effectively observing changes in blowing intensity during training. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a lung function training device. This device can record the duration of exhalation during exhalation training and convert the exhalation intensity into the intensity of current. The intensity of current can be reflected by changes in the brightness of LED beads. By recording the maximum value of current intensity, the exhalation intensity is reflected. Through changes in the brightness of LED beads, the training patient can intuitively see the changes in their breathing intensity, allowing the patient to see their training results and motivating them to participate more actively in the training.

[0004] To achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution:

[0005] A lung function training device includes an air blowing measuring cylinder and an air blowing nozzle. The air blowing nozzle is detachably fixed to the open end of the air blowing measuring cylinder. The other end of the air blowing measuring cylinder is sealed and a USB charging interface is provided at the sealed end.

[0007] Furthermore, the wind power generation mechanism includes rotating blades and a generator.

The rotating blades are positioned towards the air inlet of the air blowing measuring cylinder. An exhaust guide shroud is fixed to the front end of the generator's housing. The outer periphery of the exhaust guide shroud is fixed to the inner wall of the air blowing chamber. The exhaust port is located on the left side of the exhaust guide shroud.

[0008] Furthermore, the air nozzle is composed of a connecting sleeve and a bite mouthpiece as one piece. The connecting sleeve is inserted into the air measuring cylinder. A flow guide plug is fixed inside the connecting sleeve. The flow guide plug has several through flow guide holes, which are set perpendicular to the direction of the rotating blade.

[0009] Furthermore, the control circuit board is equipped with a processing chip, a power module, a power detection module, a switch module, a current sensor, a digital-to-analog converter module, a constant current source drive module, and a USB charging interface.

[0022] like Figure 1-2 As shown, a lung function training device includes an air blowing measuring cylinder 1 and an air blowing nozzle 2.

The other end of the air blowing measuring cylinder 1 is sealed and a USB charging interface 14 is provided at the sealed end. A display screen 11 and LED beads 12 are fixed on the air blowing measuring cylinder. Several exhaust holes 13 are opened on the air blowing measuring cylinder 1 and are arranged in a ring. A wind power generation mechanism, a storage battery 7 and a control circuit board 8 are fixed in the air blowing measuring cylinder 1. The LED beads 12, the USB charging interface 14, the wind power generation mechanism and the storage battery 7 are all connected to the control circuit board 8.

[0023] like Figure 3 As shown, a sealing isolation plate 15 is fixed in the air blowing measuring cylinder 1, the wind power generation mechanism is fixed at the center of the sealing isolation plate 15, the left side of the sealing isolation plate 15 is the air blowing chamber 16, the right side of the sealing isolation plate is the working chamber 17, the battery 7 and the control circuit board 8 are fixed in the working chamber, and the LED lamp beads 12 are fixed on the outer wall of the working chamber 17.

[0024] The air nozzle 2 is composed of a connecting sleeve and a bite nozzle 3. The connecting sleeve is inserted into the air blowing measuring cylinder. A guide plug 21 is fixed inside the connecting sleeve. The guide plug 21 has several through guide holes 22. The guide holes 22 are set perpendicular to the direction of the rotating blade 4. The blown gas will enter from the bite nozzle 3 and be aligned through the guide holes 22, so that the airflow is blown in a direction perpendicular to the rotating blade 4 of the wind power generation mechanism, preventing gas turbulence from affecting the rotation of the rotating blade 4.

[0025] The wind power generation mechanism includes a rotating blade 4 and a generator 5. The rotating blade 4 is connected to the generator via a gearbox, and the generator 5 is connected to a control circuit board 8. The rotating blade 4 is positioned towards the air inlet of the air blowing measuring cylinder 1. An exhaust guide shroud 6 is fixed to the front end of the outer casing of the generator 5. The outer periphery of the exhaust guide shroud 6 is fixed to the inner wall of the air blowing chamber 16. The exhaust port 13 is located on the left side of the exhaust guide shroud 6. The exhaust gas after passing through the rotating blade 4 will be discharged to the outside of the air blowing measuring cylinder 1 along the exhaust guide shroud 6 to the exhaust port 13 on the air blowing chamber 16.

[0026] like Figure 4 As shown, the control circuit board 8 is fixed with a processing chip 81, a power module 82, a power detection module 83, a switch module 84, a current sensor 85, a digital-to-analog converter module 86, a constant current source drive module 87, and a USB charging interface 14. The USB charging interface is connected to the battery through the switch module. The battery is connected to the processing chip through the power module. The power detection module is connected to both the battery and the processing chip. The power module and the switch module are both connected to the processing chip. The generator of the wind power generation mechanism is connected to the current sensor. The current sensor is connected to the digital-to-analog converter module. The digital-to-analog converter module and the constant current source drive module are both connected to the processing chip.

[0027] The current sensor 85 detects the micro-current intensity output by the generator 5 and converts it into an analog electrical signal. The digital-to-analog converter module 86 converts the analog electrical signal into a digital signal and transmits it to the processing chip 81. The processing chip 81 transmits the current intensity value to the display screen for display. At the same time, it outputs a corresponding PWM control signal to the constant current source drive module 87 according to the current intensity value. The constant current source drive module 87 outputs a current of corresponding intensity to the LED beads, and the LED beads will generate light of corresponding intensity, so that the patients can observe the changes in their blowing intensity during the blowing training. After the blowing is completed, the current intensity generated by the generator is zero, and the LED beads are turned off.

[0028] In this embodiment, the processing chip is an STM32F103 microprocessor chip, the digital-to-analog converter module is a DAC0832 analog-to-digital converter chip, the power supply module is an AMS1117-3.3V power supply chip, the power detection module is two LTC2949 power detection chips, the switching module is a 2AK switching diode, the current sensor is an MCS1823 small-size Hall current sensor, and the constant current source drive module is a TX6122 constant current source drive chip.

[0029] The specific application of this device is as follows: The patient inserts a disposable mouthpiece 2 into the air blowing measuring cylinder 1, then holds the mouthpiece 3 in their mouth and blows air. The blown air enters through the mouthpiece 3 and is aligned through the guide hole 22, so that the airflow is blown in a direction perpendicular to the rotating blade 4 of the wind power generation mechanism. The rotating blade 4 rotates and drives the generator 5 to generate electricity through the gearbox. The exhaust gas will be discharged from the exhaust hole 13 through the exhaust guide 6. The current sensor 85 will detect the intensity of the micro current output by the generator and convert it into an analog electrical signal. After receiving the current intensity signal converted by the digital-to-analog conversion module, the processing chip 81 will adjust the LED beads through the constant current source drive module 87. The LED beads emit light of corresponding intensity, which allows the patient to judge the change in their blowing intensity based on the brightness. At the same time, the processing chip 81 starts timing when the current is generated during blowing and stops timing when the current intensity is zero at the end of blowing to calculate the blowing time. The processing chip 81 transmits the blowing time and the maximum current value corresponding to the blowing intensity to the display screen for display, so that the patient can better understand the effect of the blowing lung function exercise and participate more actively in the subsequent lung function rehabilitation training.
