[0002] In clinical practice, many patients require pulmonary rehabilitation training due to illness or surgery. This training helps relieve respiratory muscle fatigue, improve lung function, and enhance the body's oxygen acquisition capacity, thereby increasing the patient's physical endurance. However, training methods often rely on blowing up balloons or devices, lacking diversity and personalized adjustments. Furthermore, existing equipment cannot directly display the patient's breathing status, making real-time monitoring of training effectiveness difficult without the assistance of medical personnel.

[0003] Therefore, there is an urgent need to provide a breathing training machine to solve the above problems. Utility Model Content

An air outlet connector is provided on the lower part of one side of the shell. The airflow channel is disposed inside the shell. The first port of the airflow channel is connected to the air outlet connector, and the second port of the airflow channel is connected to the air flow meter.

[0007] The detection device includes a solenoid valve, a detection device body, a rotary motor, a display screen, and a pressure detection sensor disposed within the detection device body. The detection device body is connected to a third port located between the first and second ports of the airflow channel via the solenoid valve, for receiving the blowing force transmitted through the blowing port interface, and displaying the pressure obtained by the pressure detection sensor on the display screen.

[0012] In one embodiment, the system further includes a PCB circuit and a PCB bracket that fixes the PCB circuit on the upper side inside the rear housing. The PCB circuit is electrically connected to the pressure detection sensor and the display screen.

[0013] In one embodiment, an airflow bracket is also included for securing the airflow meter to the lower side within the rear housing.

[0014] In one embodiment, the detection device body includes a moving core, an upper housing abutting one end of the moving core, a spring circumferentially sleeved on the moving core, a knob abutting the other end of the moving core, a moving core frame sleeved on a section of the spring near the upper housing, a lower outer cover sleeved on the other section of the spring, and a moving core shell abutting the end face of the spring near the knob; the rotary motor is connected to the upper housing via a synchronous belt and drives it and the moving core to rotate to compress or release the spring; the end of the knob away from the moving core is also provided with an air head, which is used to connect to the third port of the airflow channel.

The airflow channel is located inside the housing, connecting the air inlet connector and the air flow meter to form a gas flow path. A solenoid valve connects the detection device body to the third port of the airflow channel, receiving the force generated by the user's blowing. A pressure sensor is installed inside the detection device body (e.g., inside the airflow channel) to measure and acquire the blowing pressure value. A rotary motor is connected to the detection device body via a synchronous belt to adjust the breathing resistance.

[0022] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] See Figures 1 to 3 This application proposes a breathing training machine, including a rectangular shell, an airflow channel, a detection device, and an air flow meter 102. An air inlet connector 101 is provided on the lower part of one side of the shell. The airflow channel is disposed inside the shell. The first port of the airflow channel is connected to the air inlet connector 101, and the second port of the airflow channel is connected to the air flow meter 102. The rectangular shell can be upright.

[0025] The detection device includes a solenoid valve 103, a detection device body 104, a rotary motor 105, a display screen 106, and a pressure detection sensor disposed within the detection device body 104. The detection device body 104 is connected to a third port located between the first and second ports of the airflow channel via the solenoid valve 103, for receiving the blowing force transmitted through the air outlet interface, and displaying the pressure obtained by the pressure detection sensor on the display screen 106. The pulley of the rotary motor 105 is connected to the synchronous pulley 107 of the detection device body 104 via a synchronous belt to adjust the breathing resistance of the detection device body 104. A pad 127 may also be included between the display screen 106 and the housing. The detection device body 104 can be fixed inside the housing by a main frame 132, and a pad 134 may be provided between the main frame 132 and the housing.

[0026] The air inlet connector 101 is located on the lower side of the housing. The user blows air through this interface, and the gas enters the airflow channel. The airflow channel is located inside the housing, connecting the air inlet connector 101 and the air flow meter 102 to form a gas flow path. A solenoid valve 103 connects the detection device body 104 to the third port of the airflow channel, receiving the force generated by the user's blowing air. A pressure sensor is installed inside the detection device body 104 (e.g., inside the airflow channel) to measure and acquire the blowing pressure value. The pulley of the rotary motor 105 is connected to the synchronous pulley 107 of the detection device body 104 via a synchronous belt to adjust the breathing resistance. The display screen 106 displays the pressure value measured by the pressure sensor in real time, providing intuitive feedback to the user. The rotary motor 105 can adjust the resistance of the detection device body 104 according to the user's needs, thereby changing the resistance felt by the user when blowing air. The rotary motor 105 can be fixed inside the housing by the motor bracket 133.

[0027] The advantage of this design is that, compared to existing fixed and bulky rehabilitation training equipment, the breathing training machine provided in this application is compact, portable, and easy to use. The real-time display of the blowing pressure on the screen 106 allows users to instantly understand their breathing strength, facilitating effective breathing training. The design of the pulleys and timing pulleys 107 in the rotary motor 105 allows users to adjust the breathing resistance according to their individual needs, providing personalized training programs.

[0028] In summary, the breathing training machine provided in this application allows for real-time, diverse, and personalized adjustments to breathing resistance, and can directly display the patient's breathing status, enabling real-time monitoring of training effectiveness even without the assistance of medical personnel.

[0029] In one embodiment, a branch pipe head 108, a branch pipe 109, a branch core 110, a valve connector 111, and a gate valve 112 are sequentially provided between the air flow meter 102 and the second port of the airflow channel.

[0030] Air flow meter 102 measures the gas flow rate through the airflow channel, providing accurate monitoring of the gas flow rate for use in case of abnormalities on display 106. A manifold 108 is located between air flow meter 102 and the second port of the airflow channel, serving as a connecting component. A manifold 109 is connected after manifold 108 to guide airflow through manifold 110. Manifold 110 controls the airflow rate. A valve connector 111 is connected after manifold 110, serving as an interface component for connecting gate valve 112. Gate valve 112 is located after valve connector 111, serving as an adjustable valve to control the on / off state or flow rate of the airflow. By opening and closing gate valve 112, the airflow can be controlled, achieving precise control of the airflow in the breathing training machine. The airflow channel includes, for example, a U-shaped plate 128, a valve connector 129, and a tee 130.

[0031] Therefore, by adding a combination of a branch pipe head 108, a branch pipe 109, a branch core 110, a valve connector 111, and a gate valve 112 between the air flow meter 102 and the airflow channel, a more flexible, precise, and safe airflow control mechanism is provided.

[0032] In one embodiment, a connector bracket 113 is provided between the air inlet connector 101 and the first port of the airflow channel.

[0033] The user blows air into the breathing training machine through the air inlet connector 101. The connector frame 113 is located between the air inlet connector 101 and the first port of the airflow channel, which plays a supporting role and enhances the stability of the overall structure.

[0034] In one embodiment, the display screen 106 is located on the upper part of the housing on the same side as the air inlet connector 101.

[0035] The display screen 106 is located on the upper part of the housing on the same side as the air outlet connector 101, allowing users to easily view information on the display screen 106 during breathing exercises. This information includes, but is not limited to, pressure readings, flow data, and training progress. The display screen 106 provides real-time feedback, enabling users to adjust their breathing intensity and rhythm based on the displayed data. Because the display screen 106 and the air outlet connector 101 are located on the same side, users can view the information without turning their head or changing their line of sight during training, improving operational convenience.

[0036] In one embodiment, the housing includes a front shell 114 and a rear shell 115. The front shell 114 is disposed on one side of the display screen 106 and the air outlet connector 101, and the rear shell 115 is disposed on the side away from the display screen 106 and the air outlet connector 101. The design of the front and rear shells 115 can be adjusted according to the needs of the usage environment. For example, sound insulation material can be added to the rear shell 115 to reduce noise interference. A bottom plate 131 is provided inside the rear shell 115.

[0037] In one embodiment, the system also includes a PCB board circuit and a PCB bracket 116 that fixes the PCB board circuit on the upper side inside the rear housing 115. The PCB board circuit is electrically connected to the pressure detection sensor and the display screen 106.

[0038] The PCB circuitry serves as the electronic control and signal processing component in the breathing training machine. The PCB bracket 116 is used to secure the PCB circuitry, ensuring its stable installation within the device. The integrated design of the PCB circuitry simplifies internal wiring, reduces space requirements, and improves the device's compactness and reliability.

[0039] In one embodiment, an airflow bracket 117 is also included, which is used to fix the airflow meter 102 to the lower side inside the rear housing 115.

[0040] The airflow bracket 117 is used to fix the position of the airflow meter 102. Specifically, it fixes the airflow meter 102 to the lower side inside the rear housing 115 to ensure the accurate position of the airflow meter 102 in the airflow channel. At the same time, the airflow bracket 117 provides additional support, enhances the stability of the airflow meter 102, and reduces errors caused by equipment movement or vibration.

[0041] In one embodiment, the detection device body 104 includes a moving core 118, an upper housing 119 abutting one end of the moving core 118, a spring 120 circumferentially sleeved on the moving core 118, a knob 121 abutting the other end of the moving core 118, a moving core frame 122 sleeved on a section of the spring 120 near the upper housing 119, a lower outer cover 136 sleeved on the other section of the spring 120, and a moving core shell 123 abutting the end face of the spring 120 near the knob 121. A rotary motor 105 is connected to the upper housing 119 via a synchronous belt and drives it and the moving core 118 to rotate to compress or release the spring 120. An air head 124 is also provided at the end of the knob 121 away from the moving core 118, and the air head 124 is used to connect to a third port of the airflow channel. An upper outer cover 135 is also sleeved on the outside of the moving core frame 122.

[0042] A rotary motor 105 is connected to the upper housing 119 of the device via a synchronous belt. When the motor rotates, it drives the upper housing 119 and the moving core 118 to rotate, thereby compressing or releasing the spring 120 to automatically adjust the airflow resistance. An air head 124 is located at the end of the knob 121 furthest from the moving core 118. The air head 124 is connected to the third port of the airflow channel, transmitting the state changes of the moving core 118 to the airflow channel. The spring 120 is circumferentially fitted onto the moving core 118, providing variable elastic force. Simultaneously, when the user uses the breathing training machine, the moving core 118 receives air pressure and moves upwards towards the housing 119. Therefore, it is believed that the variable elastic force of the spring can change the resistance of the airflow channel.

[0043] In one embodiment, a bearing component 125 is further provided on the outer periphery of the knob 121. The bearing component 125 is mounted on the outer periphery of the knob 121, providing support and guidance for the knob 121 during rotation, ensuring the smoothness and accuracy of the knob 121's rotation. The bearing component 125 includes a bearing and a bearing base, reducing friction during the rotation of the knob 121 and improving the sensitivity of adjustment.

[0044] In one embodiment, the detection device body 104 further includes an optical coupler 126, which is used to acquire the rotation status of the moving core 118. The optical coupler 126 may consist of a light source (such as a light-emitting diode (LED)) and a photosensitive element (such as a photodiode or phototransistor), used to monitor the rotation status of the moving core 118. The rotation of the moving core 118 can change the relative position between the light source and the photosensitive element or block light. When the moving core 118 rotates, the light emitted by the light source may be partially or completely blocked, which is then detected by the photosensitive element and converted into an electrical signal, and sent to the PCB circuit.
