Figure 1As shown, the pitch angle determination device provided in this embodiment of the invention includes: a rotation drive module 10, a rotatable module 20, a rotation sensing module 30, an oscillation measurement module 40, and a control module 50; the rotation drive module 10 is connected to the rotatable module 20 and the control module 50 respectively, and is used to control the rotation of the rotatable module 20 according to the rotation control signal provided by the control module 50; the rotation sensing module 30 is used to sense the rotation information of the rotatable module 20 and transmit the rotation information to the control module 50; the oscillation measurement module 40 includes a connected breathing connection unit 41 and an oscillation measurement unit 42; the interface of the breathing connection unit 41 is disposed in the rotatable module 20; the oscillation measurement unit 42 is electrically connected to the control module 50, and is used to transmit the breathing parameters of the sample to be tested to the control module 50; the control module 50 is used to determine the pitch angle of the rotatable module 20 matching the sample to be tested according to the rotation information and the breathing parameters.

[0042] In this embodiment, the rotation drive module 10 can be understood as a functional integrated module that outputs torque from a power source to drive the target component to perform actions and to regulate the motion state of the target component. The rotatable module 20 can be understood as a structural unit that, under the drive of the rotation drive module 10, can achieve rotation, oscillation, or multi-angle adjustment around a specific axis. The control module 50 can be understood as a functional integrated unit that can receive input signals, perform signal processing and decision-making through preset logic or algorithms, and output control commands to regulate the operating state of the target component. For example, the control module 50 includes, but is not limited to, a computer, and this embodiment of the invention does not impose any limitations on it. Specifically, the rotation drive module 10 is connected to both the rotatable module 20 and the control module 50, and controls the rotatable module 20 to rotate according to the rotation control signal issued by the control module 50.

[0043] The rotation sensing module 30 can be understood as a functional unit that collects the rotational state parameters of the target component in real time through sensing elements and converts them into electrical signals for output. For example, the rotation sensing module 30 includes, but is not limited to, an angle sensor, and this embodiment of the invention does not impose any limitations on this. The rotation sensing module 30 senses the rotation information of the rotatable module 20 and transmits the rotation information to the control module 50, providing the control module 50 with motion state feedback of the rotatable module 20, thereby realizing the monitoring of the rotation angle of the rotatable module 20.

[0044] The oscillation measurement module 40 can be understood as a functional unit that collects and processes periodic oscillation signals to achieve accurate detection and analysis of oscillation parameters. Specifically, the oscillation measurement module 40 includes a connected breathing connection unit 41 and an oscillation measurement unit 42. The breathing connection unit 41 can be understood as a functional component used to establish an airway connection between the sample under test and the breathing measurement component. It can adapt to the sample's breathing movements and ensure the reliability of the breathing parameter measurement or ventilation process. The breathing connection unit 41 includes, but is not limited to, a plastic interface with a diameter of 33 cm. This embodiment of the invention does not limit this. The oscillation measurement unit 42 can be understood as a functional unit that measures periodic oscillation signals to achieve accurate analysis of oscillation parameters.

The control module 50 determines the pitch angle of the rotatable module 20 that matches the sample under test based on the rotation information of the rotatable module 20 and the acquired breathing parameters.

[0045] For example, the control module 50 sets a rotation angle command and sends a rotation command to the rotation drive module 10. Upon receiving the rotation command, the rotation drive module 10 drives the rotatable module 20 to rotate to the rotation angle set by the control module 50. The sample to be tested is connected to the interface of the breathing connection unit 41 and breathes normally. The oscillation measurement unit 42 collects and records the breathing parameters of the sample to be tested and transmits the breathing parameters of the sample to the control module 50. At the same time, the rotation sensing module 30 collects the angle of the rotatable module 20 at this time and transmits it to the control module 50. The control module 50 determines the pitch angle of the rotatable module 20 that matches the sample to be tested based on the acquired angle information of the rotatable module 20 and the breathing parameters from the oscillation measurement unit 42, and then performs lung function testing at this pitch angle.

[0046] This invention provides a pitch angle determination device. A rotation drive module 10, connected to both a rotatable module 20 and a control module 50, is included in the device. The rotatable module 20 is rotated according to a rotation control signal provided by the control module 50. A rotation sensing module 30 senses the rotation information of the rotatable module 20 and transmits it to the control module 50. An interface is provided in the rotatable module 20, connecting a respiratory connection unit 41 and an oscillation measurement unit 42 electrically connected to the control module 50, to transmit the respiratory parameters of the sample to be tested to the control module 50. The control module 50 determines the pitch angle of the rotatable module 20 that best matches the sample. By obtaining the optimal pitch angle for the sample, accurate measurement of oscillatory lung function is achieved, improving the accuracy of lung function measurement and solving the problem of measurement errors caused by different pitch angles of the sample.

[0047] Optional, you can continue to refer to Figure 1 The rotation drive module 10 includes a drive unit 11 and a motor 12. The rotatable module 20 includes a bearing 21 and a rotating beam 22. The interface of the breathing connection unit 41 is located in the rotating beam 22. The drive unit 11 is electrically connected to the control module 50 and the motor 12. The motor 12 is connected to the bearing 21, and the bearing 21 is connected to the rotating beam 22. The drive unit 11 is used to control the motor 12 to output a rotation drive signal to the bearing 21 according to the rotation control signal provided by the control module 50, so as to drive the bearing 21 to rotate and drive the rotating beam 22 to rotate.

[0048] In this embodiment, the rotation drive module 10 includes a drive unit 11 and a motor 21. The drive unit 11 can be understood as a functional unit that receives command signals from the control module, converts energy forms such as electrical energy into mechanical energy, and drives the target component to move. The drive unit 11 includes, but is not limited to, a driver of model P70530; this embodiment of the invention does not limit this. The drive unit 11 can drive the motor 12 to achieve the positioning of the rotatable module 20 at different angles. For example, the motor 12 includes, but is not limited to, a motor of model NEMA23; this embodiment of the invention does not limit this.

[0049] The rotatable module 20 includes a bearing 21 and a rotating crossbeam 22. The bearing 21 can be understood as a mechanical component used to support a rotating mechanical body and ensure rotational accuracy and smooth movement. The bearing 21 includes, but is not limited to, a single-row deep groove ball bearing of model 6200; this embodiment of the invention does not limit this. The rotating crossbeam 22 can be understood as a component whose angle can be changed under the drive of the bearing 21 and which can support the measuring components. Specifically, the interface of the breathing connection unit 41 is located in the rotating crossbeam 22.

[0050] Specifically, one end of the drive unit 11 is electrically connected to the control module 50, and the other end is electrically connected to the motor 12. The motor 12 is connected to the bearing 21, and the bearing 21 is connected to the rotating beam 22. The control module 50 sends a rotation control signal, and the drive unit 11 controls the motor 12 to output a rotation drive signal to the bearing 21 according to the rotation control signal provided by the control module 50. This drives the bearing 21 to rotate and causes the rotating beam 22 to rotate to the rotation angle set by the control module 50.

[0051] This invention, in its embodiment, incorporates a drive unit 11 and a motor 12 in the rotation drive module 10, and a bearing 21 and a rotating beam 22 in the rotatable module 20. The drive unit 11 is electrically connected to both the control module 50 and the motor 12. The motor 12 is connected to the bearing 21, which in turn is connected to the rotating beam 22. Based on the rotation control signal provided by the control module 50, the motor 12 outputs a rotation drive signal to the bearing 21, driving the bearing 21 to rotate and consequently, the rotating beam 22. This control method, where the motor 12 controls the bearing 21 to drive the beam 22, achieves automated rotation angle control for the pitch angle determination device. This improves the accuracy of rotation angle control and the efficiency of pitch angle control, while reducing device costs. It solves the problems of inaccurate pitch angle measurement, low efficiency of manual rotation angle control, and high cost due to complex device structure.

[0052] Optionally, the rotating beam 22 may include an arc-shaped rotating beam.

[0053] The material of the arc-shaped rotating crossbeam includes, but is not limited to, acrylic; the inner radius of the arc includes, but is not limited to, 15cm; the outer radius includes, but is not limited to, 20cm; and the thickness includes, but is not limited to, 5cm. This embodiment of the invention does not impose any limitations on these aspects. The arc-shaped rotating crossbeam can effectively conform to the shape of the sample under test, achieving uniform contact within the surface area and ensuring the accuracy of the measurement results. Furthermore, the arc-shaped rotating crossbeam can adapt to samples of different shapes and sizes, improving the versatility of the equipment. This solves the problems of errors caused by unstable contact and poor sample compatibility.

[0054] Optional, you can continue to refer to Figure 1 The pitch angle determination device also includes a support module 60 and a lifting module 70; the support module 60 is connected to the lifting module 70 and the rotatable module 20 respectively; the lifting module 70 is used to adjust the height of the support module 60 to adjust the height of the rotatable module 20.

[0055] Optionally, the control module 50 is also electrically connected to the lifting module 70 for controlling the lifting height of the lifting module 70.

[0056] In this embodiment, the support module 60 can be understood as a structural unit that provides fixed support for the overall equipment or core functional components, ensuring installation stability. For example, the support module 60 includes, but is not limited to, two acrylic columns with dimensions of 5cm × 5cm × 20cm; this embodiment of the invention does not impose limitations on this. The height-adjustable module 70 can be understood as a motion unit capable of height adjustment along a specific direction, adapting to the size requirements of different scenarios or samples.

[0057] Specifically, the control module 50 is electrically connected to the liftable module 70, and controls the lifting height of the liftable module 70 through control commands. The support module 60 is connected to both the liftable module 70 and the rotatable module 20. The liftable module 70 adjusts the height of the rotatable module 20 by adjusting the height of the support module 60, thus adapting to test samples of different heights.

[0058] For example, the operator inputs a target height command to the control module 50 based on the height of the sample to be tested, and drives the lifting module 70 to adjust its height. During the lifting process of the lifting module 70, the height of the support module 60 changes synchronously, causing the rotatable module 20 to rise and fall as a whole, so that the rotatable module 20 is adjusted to a height that matches the sample to be tested, making it easier to test the sample.

[0059] This invention, in its embodiment, incorporates a liftable module 70 and a support module 60 connected to both the liftable module 70 and the rotatable module 20 within the pitch angle determination device. By adjusting the height of the liftable module 70, the height of the rotatable module 20 is adapted to the height of the sample to be tested, enabling precise measurement of lung function parameters for samples at different heights. No equipment components need to be replaced during the measurement process; adaptation is achieved solely through height adjustment. A control module electrically connected to the liftable module 70 automatically controls its lifting height via control commands, achieving automated and precise control of the liftable module 70. This improves measurement accuracy and efficiency, avoids height positioning deviations caused by manual visual inspection or manual knob adjustments, and eliminates the time-consuming manual adjustments required, further ensuring the reliability of the measurement data.

[0060] Optional, you can continue to refer to Figure 1 The pitch angle determination device also includes a data acquisition module 80; the data acquisition module 80 is electrically connected to the rotation sensing module 30 and the control module 50 respectively, and is used to acquire rotation information and transmit the rotation information to the control module 50.

[0061] In this embodiment, the acquisition module 80 can be understood as a functional unit that captures target physical quantities or electrical signals through sensing elements or data interfaces, and converts them into processable raw data to provide a basic data source for subsequent analysis and control. For example, the acquisition module 80 includes, but is not limited to, a USB3100N data acquisition device; this embodiment of the invention does not impose such limitations. Specifically, the acquisition end of the acquisition module 80 is electrically connected to the rotation sensing module 30 for acquiring rotation information, and the output end is electrically connected to the control module 50 to transmit the acquired rotation information to the control module 50.

[0062] For example, the rotatable module 20 rotates around the rotation axis, causing the built-in rotation sensing module 30 to move synchronously. The rotation sensing module 30 detects the rotation angle and rotation speed information of the rotating beam 22 in real time, converts them into pulse signals, and transmits them to the acquisition module 80. After receiving the signal, the acquisition module 80 filters and converts the signal into digital angle data that can be recognized by the control module 50, and transmits it to the control module 50.

[0063] This invention, in its embodiment, incorporates a data acquisition module 80 within the pitch angle determination device. This module 80 is electrically connected to both the rotation sensing module 30 and the control module 50. It acquires rotation information and transmits it to the control module 50, achieving precise capture, stable transmission, and standardized processing of this information. This provides real-time feedback data to the control module 50, accurately obtaining pitch angle information and enabling precise closed-loop control of the rotatable module 20's angle, thus facilitating accurate measurement of oscillatory lung function. This avoids data loss or misreading due to incompatible signal formats, ensuring the stability of data transmission.

[0064] Optional, you can continue to refer to Figure 1 The breathing connection unit 41 includes a flexible breathing connection unit 90.

[0065] In this embodiment, the flexible breathing connection unit 90 can be understood as a functional component made of flexible material, used to establish an airway connection between the test subject and the breathing device. For example, the flexible breathing connection unit 90 includes, but is not limited to, silicone tubing; this embodiment of the invention does not impose any limitations on this.

[0066] Specifically, the oscillation measurement unit 40 is connected to the interface of the breathing connection unit 41 via the flexible breathing connection unit 90, and is used to acquire the lung function parameters of the sample to be tested, thereby realizing the measurement of the lung function parameters of the sample to be tested. For example, the sample to be tested breathes through the interface of the breathing connection unit 41, and the breathing airflow is transmitted to the oscillation measurement unit 42 through the flexible breathing connection unit 90. The oscillation measurement unit 42 measures the lung function parameters based on the acquired breathing airflow and transmits the measurement results to the control module 50.

[0067] In this embodiment of the invention, a flexible breathing connection unit 90 is connected to the interface of the breathing connection unit 41 and the oscillation measurement unit 42. The flexible breathing connection unit 90 acts as a bridge for airflow transmission, enabling the oscillation measurement unit 42 to accurately collect the respiratory data of the sample under test, thus achieving the measurement of lung function parameters. This design ensures good airtightness of the airway and avoids airway bends and blockages, stabilizing airflow transmission, reducing data fluctuations, and ensuring the accuracy of lung function parameter measurements. Furthermore, it reduces installation and debugging difficulty, improves measurement efficiency, and solves the problem of data errors caused by poor connection sealing.

[0068] Based on the same inventive concept, embodiments of the present invention also provide a method for determining the pitch angle.

The pitch angle determination method can be applied to the pitch angle determination device provided in any of the above optional embodiments. Figure 2 As shown, the methods for determining the pitch angle include:

[0069] S101, output rotation control signal to rotation drive module to control rotation drive module to output rotation drive signal to rotatable module, so that rotatable module rotates and drives breathing connection unit to rotate.

[0070] Specifically, the rotation drive module can be understood as an integrated module that outputs torque from a power source to drive a target component to perform actions and to regulate the motion state of the target component. The rotatable module can be understood as a structural unit that, driven by the rotation drive module, can rotate, swing, or adjust at multiple angles around a specific axis. The rotation drive module is connected to both the rotatable module and the control module. The control module outputs rotation control signals to the rotation drive module, which in turn controls the rotation drive module to output rotation drive signals to the rotatable module, thus controlling the rotatable module to rotate.

[0071] S102, Receive rotation information of the rotatable module sensed by the rotation sensing module.

[0072] Specifically, the rotation sensing module can be understood as a functional unit that collects the rotational state parameters of the target component in real time through sensing elements and converts them into electrical signals for output. The rotation sensing module is connected to both the rotatable module and the control module. It senses the rotation information of the rotatable module and transmits it to the control module, providing the control module with motion state feedback of the rotatable module. The control module receives the rotation information and monitors the rotation angle of the rotatable module.

[0073] S103, Receive the respiratory parameters of the sample to be tested measured by the oscillation measurement unit.

[0074] Specifically, the oscillation measurement module includes a connected breathing connection unit and an oscillation measurement unit. The interface of the breathing connection unit is located in the rotatable module, and the oscillation measurement unit is electrically connected to the control module to measure the respiratory parameters of the sample and transmit the respiratory parameters of the sample to the control module.

[0075] S104. Determine the pitch angle of the rotatable module that matches the sample to be tested based on the rotation information and breathing parameters.

[0076] Specifically, the control module receives rotation information from the rotation sensing module and respiratory parameters from the oscillation measurement module. Based on the rotation information and the acquired respiratory parameters, the control module determines the pitch angle of the rotatable module that matches the sample to be tested.

[0077] This invention employs the above-described pitch angle determination method. A control module outputs a rotation control signal to a rotation drive module, which in turn outputs a rotation drive signal to a rotatable module, causing the rotatable module to rotate. A rotation sensing module senses the rotation information of the rotatable module and transmits it to the control module. An oscillation measurement module measures the respiratory parameters of the sample and transmits these parameters to the control module. The control module determines the pitch angle of the rotatable module that best matches the sample based on the rotation information and respiratory parameters. By precisely adjusting the pitch angle through control, acquisition, and feedback, the most suitable pitch angle for the sample is obtained, enabling accurate measurement of oscillatory lung function. This improves the accuracy and efficiency of lung function measurement and solves the problem of measurement errors caused by different pitch angles of the sample.

[0078] Figure 3 This is a flowchart of another pitch angle determination method provided by an embodiment of the present invention. This embodiment elaborates in detail on the method for determining the pitch angle of the rotatable module matching the sample to be tested, based on the above-described implementation. For example... Figure 3 As shown, the method specifically includes:

[0079] S201. Output rotation control signal to rotation drive module to control rotation drive module to output rotation drive signal to rotatable module, so that rotatable module rotates and drives breathing connection unit to rotate.

[0080] S202, Receive rotation information of the rotatable module sensed by the rotation sensing module.

[0081] S203, Receive the respiratory parameters of the sample under test measured by the oscillation measurement unit.

[0082] S204. Determine the corresponding respiratory parameters for different rotation angles based on rotation information and respiratory parameters. The respiratory parameters include respiratory resistance parameters.

[0083] Specifically, the oscillation measurement module measures the respiratory parameters of the sample under test, and uses the respiratory resistance parameter among these parameters as a reference standard for determining the pitch angle, thereby comprehensively assessing the overall state of the respiratory system. For example, the respiratory resistance parameter includes, but is not limited to, a 5Hz respiratory resistance measurement value; this embodiment of the invention does not impose limitations on this.

[0084] S205. Determine the rotation angle corresponding to the minimum breathing resistance parameter as the pitch angle of the rotatable module that matches the sample to be tested.

[0085] Specifically, the control module sets a preset rotation angle and sends a rotation signal to control the rotation drive module to gradually increase the rotation angle of the rotatable module. The oscillation measurement module measures and records the respiratory resistance parameters at each target rotation angle and transmits them to the control module. Simultaneously, the rotation sensing module measures and feeds back the corresponding rotation information to the control module. When the rotatable module rotates to the preset angle, the control module controls the rotation drive module to return to the initial position. The control module compares the measured respiratory resistance parameters at each rotation angle, obtains the minimum measured respiratory resistance parameter, and obtains the rotation angle of the rotatable module corresponding to the minimum value. The control module continues to control the rotation drive module to adjust the rotatable module to the angle corresponding to the minimum respiratory resistance parameter, and the formal measurement begins.

[0086] For example, the control module outputs a control signal to control the drive unit to drive the motor to increase the clockwise rotation angle by 5°. The oscillation measurement module measures and records the 5Hz respiratory resistance parameter of the sample under test, and the rotation sensing module provides feedback on the 5° angular displacement. The control drive unit continues to drive the motor to increase the clockwise rotation angle, and the oscillation measurement module measures and records the 5Hz respiratory resistance parameter of the sample under test at each rotation angle. The rotation sensing module provides feedback on the angular displacement to the control module. When the rotatable module reaches a rotation angle of 30°, the oscillation measurement module measures and records the 5Hz respiratory resistance parameter, and the motor returns to its initial position. The control module continues to control the drive unit to drive the motor to complete the above process counterclockwise. When the rotatable module reaches a rotation angle of -30°, the oscillation measurement module measures and records the 5Hz respiratory resistance parameter, and the motor returns to its initial position. The control module compares the 5Hz respiratory resistance parameters recorded in each measurement, obtains the minimum value of the 5Hz respiratory resistance parameter measured in each measurement, and obtains the rotation angle of the rotatable module corresponding to the minimum value. This rotation angle is the pitch angle that best matches the sample to be tested. The control module controls the motor to adjust the rotatable module to this angle and begins to formally measure the lung function parameters.

[0087] This invention employs the above technical solution, using a control module to obtain the minimum value of the respiratory resistance parameter in the respiratory parameters of the sample under test as the standard for determining the pitch angle of the sample. The rotation angle corresponding to the minimum respiratory resistance parameter is then used as the pitch angle of the rotatable module matched to the sample. This eliminates the need for repeated manual adjustments to the rotatable module angle and individual resistance tests. The system automatically collects respiratory resistance data at different angles, filters out the angle corresponding to the minimum value, significantly improving operational efficiency and accurately obtaining the pitch angle best matched to the sample, thus achieving precise measurement of oscillatory lung function. This solves the measurement error problem caused by manual judgment of the rotatable module's pitch angle based on experience and the low efficiency of manual adjustment.

[0088] Optionally, the pitch angle determining device further includes a connected support module and a liftable module, with the support module connected to the rotatable module; the pitch angle determining method further includes: outputting a lifting control signal to the liftable module to control the lifting height of the liftable module and adjust the height of the support module and the rotatable module.

[0089] Specifically, the control module is electrically connected to the liftable module and controls the lifting height of the liftable module through control commands. The support module is connected to both the liftable module and the rotatable module. The liftable module adjusts the height of the support module to adjust the height of the rotatable module, so that the rotatable module is adjusted to a height that matches the sample to be tested, making it convenient for testing the sample.

[0090] This invention employs the above technical solution, adjusting the height of the liftable module via a control module to match the height of the rotatable module with the height of the sample to be tested. This enables accurate measurement of lung function parameters for samples at different heights. No equipment components need to be replaced during the measurement process; adaptation to different samples is achieved solely through height adjustment. This improves measurement accuracy and efficiency, avoids height positioning deviations caused by manual visual inspection or manual knob adjustments, and eliminates the time-consuming process of repeated manual adjustments, further ensuring the reliability of the measurement data.
