[0042] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a respiratory data detection system provided in this embodiment.

[0044] The respiratory data detection system includes an oscillation device, a detection device and a signal processing device. The oscillation device includes an oscillator 303 and an oscillation tube 304. The detection device includes a pressure difference flow detection device 100, a respiratory detection excitation device 201 and a respiratory device 202. The oscillator 303 is connected to the oscillation tube 304. The oscillation tube 304 is connected to the pressure difference flow detection device 100. The pressure difference flow detection device 100 and the respiratory detection excitation device 201 are both connected to the respiratory device 202. The respiratory detection excitation device can store respiratory detection excitation drugs, such as common asthma excitation drugs. The signal processing device can be a microprocessor unit, a computer and other devices, such as Figure 1 The computer host shown in FIG. The components with communication functions in the oscillation device and the detection device, such as the pressure difference flow detection device and the breathing detection excitation device, can communicate with the signal processing device and be controlled by the signal processing device.

[0045] The respiratory data detection system can also include a test bench 200, a trolley 300, a display 301 and a computer host 302, wherein the trolley 300 can be provided with corresponding moving wheels for easy movement at any time, and the test bench 200, the display 301, the computer host 302, the oscillation tube 304 and the oscillator 303 are all arranged on the trolley 300.

[0046] The oscillation device is mainly used to generate oscillation waves, through which the air in the oscillation tube is squeezed into the pressure difference flow detection device and the breathing device.

[0047] The oscillator 303 is mainly used to generate regular oscillation waves, which squeeze the air in the oscillation tube 304, so that the air in the oscillation tube 304 can flow through the pressure difference flow detection device 100 at a fixed flow rate and enter the breathing device 202. The breathing device 202 is mainly used for the subject to breathe when performing breathing data detection.

[0048] The pressure difference flow detection device is mainly used to obtain the first air supply flow of the air flowing from the oscillation tube into the breathing device, and send the first air supply flow to the signal processing device.

[0049] When the subject breathes through the breathing device 202, the subject generates a breathing flow, so the air in the oscillation tube 304 is subject to the resistance generated by the subject's breathing when entering the breathing device 202. For example, the air flow rate injected into the breathing device 202 by the oscillation tube 304 is 10, and due to the resistance generated by the user's breathing, the flow rate that finally enters the breathing device 202 may be 8, that is, the first air supply flow rate is 8.

[0050] The signal processing device is mainly used to determine whether the breathing detection excitation device is turned on. If it is turned on, the second air supply flow of the air flowing from the oscillation tube into the breathing device is obtained through the pressure difference flow detection device.

[0051] The bronchial provocation test is a method for determining airway hyperresponsiveness by stimulating the contraction reaction of the airway with some chemical, physical or biological stimulation, causing the bronchial smooth muscle to contract, and then performing a lung function test to determine the degree of bronchial stenosis. This test is a common method for performing respiratory detection. The respiratory detection and stimulation device 201 is mainly used to inject corresponding respiratory detection and stimulation drugs into the respiratory device 202. If the subject has abnormal breathing, after inhaling the respiratory detection and stimulation drugs, a corresponding abnormal breathing reaction will occur, thereby causing an increase in respiratory resistance. If the air flow rate injected into the respiratory device 202 by the oscillation tube is 10, due to the increase in the respiratory resistance of the subject, the flow rate that finally enters the respiratory device 202 may be 6, that is, the second air supply flow rate is 6.

[0052] This embodiment uses a pressure difference flow detection device to obtain the air supply flow of the oscillation device tube before and after the breathing detection excitation device is turned on, to replace the traditional method of directly obtaining the breathing flow of the person to be tested. Since the air supply flow of the oscillation tube is more stable than the breathing flow of the person to be tested, the obtained air supply flow is then sent to a signal processing device for subsequent detection. Therefore, by judging the change in the air supply flow, the result of the breathing data detection can be made more accurate.

[0053] In one embodiment, referring to Figure 2 The detection device also includes: an oral pressure tube 205, which is arranged at the inlet of the breathing device 202, and one end of the breathing device 202 connected to the pressure difference flow detection device 100 is fixed by a fixing ring 207, and the main body of the breathing device 202 is fixed on the support plate 204 by screws 206, and the breathing detection excitation device 201 is connected to the breathing device 202 through a sealing joint 203.

[0054] The oral pressure tube is used to obtain the first oral pressure of the subject to be tested;

[0055] The signal processing device is used to determine whether the breathing detection excitation device is turned on. If it is turned on, the second oral pressure of the person to be tested is obtained through the oral pressure tube.

[0056] When the subject breathes through the inlet of the breathing device 202, the oral pressure tube 205 can detect the oral pressure of the subject. Before the breathing detection excitation device 201 is turned on, the subject is in a normal breathing state. At this time, the first oral pressure detected can be regarded as the oral pressure during normal breathing.

[0057] When the breathing detection excitation device 201 is turned on, the breathing detection excitation drug in the breathing detection excitation device 201 is injected into the breathing device 202. The subject will inhale the drug when breathing through the breathing device 202. If the subject has abnormal breathing, a corresponding abnormal breathing reaction will occur, and the oral pressure will increase. At this time, the second oral pressure measured by the oral pressure tube 205 is the breathing pressure when the subject has an abnormal breathing reaction.

[0058] In this embodiment, the oral pressure of the subject before and after inhaling the breath detection stimulating drug is obtained through the oral pressure tube, and used as the data for subsequent detection to improve the detection accuracy of the breath data.

[0059] In one embodiment, the signal processing device is further used for:

[0060] Dividing the first oral cavity pressure by the first air supply flow rate to obtain a first respiratory resistance;

[0061] Dividing the second oral cavity pressure by the second air supply flow rate to obtain a second respiratory resistance;

[0062] A resistance difference is calculated based on the first respiratory resistance and the second respiratory resistance, and the detection device is controlled to be closed based on the resistance difference.

[0063] The first oral cavity pressure and the first air supply flow rate are both data before the breathing detection and excitation device 201 is turned on, and the second oral cavity pressure and the second air supply flow rate are both data after the breathing detection and excitation device 201 is turned on, so as to calculate the first breathing resistance of the subject under normal breathing and the second breathing resistance of the subject after inhaling the breathing detection and excitation drug. If the resistance difference is large, it means that there is an abnormality in the breathing data, and at this time the signal processing device can control the detection device to close to terminate the breathing data detection process.

[0064] In this embodiment, the respiratory resistance of the subject before and after the inhalation of the stimulating drug is detected. Compared with directly detecting the respiratory resistance of the subject through the respiratory flow rate and other data, the detection result is more accurate.

[0065] In one embodiment, the signal processing device is further used for:

[0066] If the resistance difference is greater than or equal to a first threshold, controlling the detection device to be turned off;

[0067] If the resistance difference is less than the first threshold, the detection device is controlled to continue running.

[0068] When the subject has an abnormal breathing reaction, such as an asthmatic reaction, the breathing resistance will increase compared to normal breathing. Therefore, the difference between the second breathing resistance and the first breathing resistance can be calculated to determine whether the subject needs to turn off the detection equipment.

[0069] Reference Figure 3 , Figure 3 A schematic diagram of the structure of an oscillator provided in this embodiment.

[0070] The oscillator 303 includes an oscillation box 3031, which is provided with an air inlet connector and an air outlet connector. One end of the air inlet connector is connected to the external air, and the other end of the air inlet connector is connected to the oscillation tube 304. The oscillation tube 304 is connected to the air outlet connector, and the air outlet connector is connected to the pressure difference flow detection device 100.

[0071] The air inlet connector is used to draw the air into the oscillation tube 304;

[0072] The oscillator is used to squeeze the air in the oscillation tube 304 through the oscillation wave, and input the air into the pressure difference flow detection device 100 and the breathing device 202 through the air outlet connector.

[0073] The air inlet connector is connected to the outside air, and the air outlet connector is connected to the pressure differential flow detection device 100 and the breathing device 202. The oscillator 303 presses the air in the oscillation tube 304 into the breathing device 202 through the air outlet connector by means of oscillation waves. At this time, the pressure differential flow detection device 100 can detect the air flow from the oscillation tube 304 into the breathing device 202. When the air in the oscillation tube 304 decreases, the outside air enters the oscillation tube 304 through the air inlet connector, thereby achieving the stability of the air flow in the oscillation tube 304.

[0074] This embodiment achieves the stability of air supply flow by providing an air inlet connector to inject external air into the oscillation tube, and provides an air outlet connector to inject the air in the oscillation tube into the breathing device, thereby improving the accuracy of the breathing data detection results.

[0075] Reference Figure 4 , Figure 4 A schematic diagram of the internal structure of an oscillator provided in this embodiment.

[0076] The oscillation tube 304 includes an air resistance tube 3034, and the air resistance tube 3034 is arranged at one end close to the air inlet joint, and the diameter of the air resistance tube 3034 is smaller than the aperture of the air inlet joint.

[0077] The oscillator 303 is used to apply pressure to the oscillation tube 304, and the air resistance tube 3034 is used to block the air inlet connector 3032 so that the air in the oscillation tube 304 flows into the pressure difference flow detection device 100 and the breathing device 202 through the air outlet connector 3033.

[0078] Since both ends of the oscillation tube 304 are through structures, one end is connected to the external air through the air inlet connector 3032, and the other end is connected to the breathing device 202 through the air outlet connector 3033. Therefore, when the air in the oscillation tube 304 is squeezed by the shock wave, the air will flow out from the air inlet connector 3032 and the air outlet connector 3033 respectively, which may cause insufficient air flow at the air outlet connector 3033. In order to avoid this situation, an air resistance tube 3034 can be set at the air inlet connector 3032. The diameter of the air resistance tube 3034 is smaller than the aperture of the air inlet connector. The aperture of the air inlet connector is generally the same as the aperture of the air outlet connector. Therefore, the air resistance tube 3034 can increase the resistance of the air in the oscillation tube 304 to flow out through the air inlet connector, thereby ensuring that most of the air will enter the breathing device 202 through the air outlet connector.

[0079] Alternatively, a corresponding valve may be provided in the air resistance tube 3034 to close the air inlet connector 3032 when the shock wave squeezes the air in the shock tube 304, and to open the air inlet connector 3032 when the shock wave does not squeeze the air, thereby ensuring that the air in the shock tube 304 can be injected into the breathing device 202, thereby making the detection result more accurate.

[0080] Reference Figure 5 , Figure 5 A cross-sectional view of an oscillator provided in this embodiment.

[0081] The oscillator 303 includes a speaker 3035 and a paper cone.

[0082] The speaker 3035 is used to make the voice coil of the speaker 3035 vibrate and drive the paper cone to vibrate according to the working current;

[0083] The paper cone is used to vibrate the air in the vibration device and generate the vibration wave.

[0084] The oscillator 303 mainly generates oscillating air waves of a fixed frequency through the speaker 3035, so that the air flow injected into the breathing device 202 by the oscillation tube 304 is stable, so as to improve the accuracy of the detection result.
