[0031] The technical scheme of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the following described embodiments are part of the embodiments of the utility model, not all embodiments.
[0032] Referring to Figures 1 to 2 The embodiment provides an air control breathing training device.
[0033] The pneumatic breathing training device comprises a shell 100, an air pipe 200, a microphone 300, a driving circuit board 400, a plurality of light emitting elements 500 and a controller.
[0034] The shell 100 is internally provided with a hollow inner cavity 110, the air pipe 200 is connected with the shell 100 and communicates with the inner cavity 110.
[0035] The driving circuit board 400 is arranged in the inner cavity 110 and is electrically connected with the microphone 300, the microphone 300 sends the picked-up audio signal to the driving circuit board 400, and the driving circuit board 400 converts the audio signal into a light control signal.
[0036] The rear side wall of the inner cavity 110 is provided with a through opening 111, the driving circuit board 400 is provided with a switch 410 for controlling the start or shutdown of the driving circuit board 400, and the switch 410 extends out of the shell 100 from the opening 111.
[0037] The plurality of light emitting elements 500 are arranged in the shell 100 so as to observe the lighting of the light emitting elements 500 from the outside of the shell 100.
[0038] The controller is arranged on the driving circuit board 400 and is electrically connected with the driving circuit board 400, the driving circuit board 400 sends the light control signal to the controller, the controller continuously receives the light control signal, and controls the plurality of light emitting elements 500 to be sequentially lighted up within the continuous time.
[0039] The patient blows air against the air pipe 200, the airflow flows through the microphone 300 in the air pipe 200, so that the microphone 300 can pick up the audio signal of the airflow flowing in the air pipe 200, the driving circuit board 400 converts the audio signal into a light control signal and sends it to the controller, the controller continuously receives the light control signal, and controls the plurality of light emitting elements 500 to be sequentially lighted up within the continuous time of receiving the light control signal; therefore, the patient activates different numbers of light emitting elements 500 by blowing air for different lengths of time, which can help the user to blow air evenly, improve the training effect, make the blowing training more intuitive, and stimulate the patient's confidence and pleasure for the breathing training.
[0040] The controller can be implemented using pure hardware circuitry. For example, digital logic circuitry can be used to sequentially illuminate multiple light-emitting elements 500 based on the duration of the audio signal picked up by the microphone 300. Alternatively, the controller can combine hardware circuitry and software, using software programming to sequentially illuminate multiple light-emitting elements 500 based on the duration of the audio signal picked up by the microphone 300. The controller can be a microcontroller, an FPGA (Field-Programmable Gate Array), or similar device.
[0041] In some embodiments, the light-emitting elements 500 emit different colors.
[0042] During the patient's breathing training, multiple light-emitting elements 500 of different colors are lit up in sequence. The patient can judge the duration of breathing based on the color of the light-emitting element 500, which helps the patient to quickly judge the duration of the breathing training.
[0043] In some embodiments, there are three light-emitting elements 500, and the light-emitting colors of the three light-emitting elements 500 are red, yellow and green, respectively.
[0044] The patient can verify the degree of breathing training by observing the red, yellow, and green lights of the three light-emitting elements 500. In this embodiment, the three light-emitting elements 500 are lit sequentially, with a 5-second interval between red and yellow, and a 5-second interval between yellow and green. The patient determines that the required duration of the exhalation has been achieved when the green light-emitting element 500 is lit. For example, when the patient exhales continuously, the microphone 300 receives the audio signal of the airflow. The driver circuit board 400 converts the audio signal into a light control signal. The controller continuously receives the light control signal and lights up the red light-emitting element 500. When the duration of the light control signal received by the controller is greater than 5 seconds, the controller lights up the yellow light-emitting element 500. When the duration of the light control signal received by the controller is greater than 10 seconds, the controller lights up the green light-emitting element 500.
[0045] In some embodiments, refer to Figure 1 and Figure 2 As shown, the air-controlled breathing trainer is also equipped with sound insulation cotton 600, which covers the outer wall of the ventilation tube 200.
[0046] The sound insulation cotton 600 absorbs noise from the outside of the ventilation tube 200, reducing the transmission of external noise to the microphone 300 through the side wall of the ventilation tube 200. This ensures that the audio signal picked up by the microphone 300 is the patient's breathing sound, which helps improve the accuracy of the microphone 300 in picking up the audio signal. Even if the patient's breathing force is small, the microphone 300 can still pick up the audio signal smoothly.
[0047] In some embodiments, refer to Figure 2 As shown, the bottom end of the ventilator 200 extends downward into the inner cavity 110, and the microphone 300 is located at the bottom end of the ventilator 200.
[0048] The air blown out by the patient needs to flow through the entire ventilation tube 200, which helps to generate vibration and sound within the ventilation tube 200 during the airflow process. Even if the patient blows with a small force, the microphone 300 can still successfully pick up the audio signal.
[0049] In some embodiments, refer to Figure 2 As shown, the air-controlled breathing trainer is also equipped with foam 700, which is installed on the outer wall of the bottom end of the air tube 200, while the microphone 300 is located at the bottom end of the air tube 200.
[0050] Foam 700 can prevent noise generated by airflow inside the inner cavity 110 from being transmitted to the bottom of the vent tube 200.
[0051] In some embodiments, refer to Figure 1 and Figure 2 As shown, the ventilator 200 bends backward to form a curved section 210.
[0052] The curved section 210 is designed to redirect the airflow blown out by the patient. This redirection of the airflow generates vibrations and produces sound, which helps to create a louder sound within the ventilation tube 200. Even if the patient blows with a weak force, the microphone 300 can still pick up the audio signal smoothly.
[0053] In some embodiments, refer to Figure 2 As shown, the air-controlled breathing trainer is also equipped with a power supply 800, which is installed in the inner cavity 110 of the housing 100. The power supply provides electrical energy to the microphone 300, the drive circuit board 400, multiple light-emitting elements 500 and the controller.
[0054] The air-controlled breathing trainer can be powered by an electric power source, eliminating the need for an external power supply, so that patients can use it anytime and anywhere.
[0055] In some embodiments, a gap is provided between the microphone 300 and the inner wall of the vent 200.
[0056] After the patient blows air into the airway 200, the airflow passes through the gap between the microphone 300 and the inner wall of the airway 200, which helps to create a larger vibration and produce a louder sound, ensuring that the microphone 300 can continuously receive sound.
[0057] In some embodiments, the front half of the vent 200 bends backward and extends backward, and a plurality of light-emitting elements 500 are disposed on the housing 100 and are located in front of the vent 200.
[0058] When the patient blows air into the front end of the ventilation tube 200, they can observe the illumination of the multiple light-emitting elements 500 in front of them, so that the patient can judge the effect of their own blowing training in a timely manner.
[0059] When a patient blows air through the ventilation tube 200, the airflow produces sound, which is picked up by the microphone 300. The duration of this sound is used to assess the patient's respiratory muscle strength. Specifically, the patient blows air through the ventilation tube 200 to the microphone 300 inside the housing 100. The microphone 300 picks up the airflow sound and sends the audio signal to the drive circuit board 400. The drive circuit board 400 continuously receives the audio signal and converts it into a light control signal. When the duration of the light control signal is less than 5 seconds, the red light-emitting element 500 lights up. When the duration of the light control signal is between 5 and 10 seconds, both the red and yellow light-emitting elements 500 light up simultaneously. When the duration of the light control signal is greater than 10 seconds, the red, yellow, and green light-emitting elements 500 light up simultaneously.
[0060] The microphone 300 is more sensitive to detecting the airflow than other training devices, and can detect faint breathing sounds. It also activates different colored light-emitting elements 500 by the duration of the breath, making the training more intuitive and boosting the patient's confidence and enjoyment in breathing training.
[0061] The driver circuit board 400 has a storage chip that can record respiratory training data from multiple patients at different times, making the respiratory training data more quantifiable. Further expansion functions such as a display screen and automatic reset can be derived based on this invention.
[0062] Compared to other breathing training devices, the air-controlled breathing trainer in this embodiment has a simple structure and low cost.
[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
