[0041] 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.

[0042] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a detection system provided in this embodiment.

[0043] The detection system includes: a central tube 205, a pressure difference flow detection device 100, an atomizer cup 204, a flow deviation device and a signal processing device. The pressure difference flow detection device 100 is connected to the outlet of the central tube 205. The flow deviation device and the atomizer cup 204 are respectively arranged in the middle of the central tube 205. The distance between the flow deviation device and the entrance of the central tube 205 is smaller than the distance between the atomizer cup 204 and the entrance of the central tube 205. The central tube 205, the pressure difference flow detection device 100, the atomizer cup 204 and the flow deviation device are all arranged on the support plate 203. The central tube 205 is fixed to the support plate 203 at one end by a fixing ring 208. The main body of the central tube 205 is fixed to the support plate 203 by a hand screw 207 so as to be disassembled at any time.

[0044] The signal processing device can be a microprocessor chip, a computer or other device, which is used to connect with any device in the system to control each device in the detection system.

[0045] When performing lung function testing on a user, it is necessary to determine whether the user has breathing disorders based on the user's real-time breathing conditions, thereby determining whether the user's lung function is normal. In this embodiment, the user's breathing is tested through the centralized tube 205. The user can connect the disposable mouthpiece to the inlet of the centralized tube 205 and breathe. The user's breathing data is tested through the pressure difference flow detection device 100 at the outlet of the centralized tube 205.

[0046] In order to prevent the gas exhaled by the user from entering the interior of the central tube 205, a bias flow device is provided at the entrance of the central tube 205, so that the gas exhaled by the user through the entrance of the central tube 205 can be promptly drawn away by the bias flow device. In order to promptly determine whether the detection has started, the pressure at the entrance of the central tube 205 can be detected for judgment.

[0047] If the pressure at the entrance of the central pipe 205 is greater than the preset pressure threshold, it can be determined that the detection has begun. At this time, the bias flow device can be turned on and its power can be adjusted to the first power to promptly extract the gas exhaled by the user.

[0048] If a user has breathing abnormalities such as asthma, the symptoms will usually only occur in certain places and at specific times. Therefore, to detect whether a user has breathing abnormalities such as asthma, the user is usually required to inhale a corresponding stimulant. If the user has breathing abnormalities, the user will experience corresponding symptoms after inhaling the stimulant. If the user does not have breathing abnormalities, the corresponding symptoms will not be triggered.

[0049] The atomizer cup is usually used to store the corresponding stimulant. When the atomizer cup 204 is opened to input the stimulant in the atomizer cup 204 into the collecting tube 205, the flow rate in the collecting tube 205 will increase accordingly. At this time, the power of the bias flow device needs to be increased accordingly to avoid insufficient power of the bias flow device, which causes the gas exhaled by the user to enter the interior of the collecting tube 205. Although increasing the power of the bias flow device will draw away a part of the stimulant, the bias flow device is closer to the entrance of the collecting tube 205, and therefore, the bias flow device will give priority to drawing away the gas exhaled by the user. The power of the bias flow device is fixed, that is, the gas flow rate that can be drawn away is fixed. Therefore, after drawing away the gas exhaled by the user, the bias flow device can only draw away a part of the stimulant at most, thereby ensuring that most of the stimulant can be inhaled by the user and that the detection can be carried out normally.

[0050] In this embodiment, when the pressure at the entrance of the central tube meets the first preset condition, the bias flow device is turned on to extract the gas exhaled by the user from the central tube 205. When the atomizer cup 204 is opened, the power of the bias flow device is increased to the second power, so that the bias flow device can not only extract the gas exhaled by the user, but also minimize the amount of the exciter extracted, thereby avoiding cross infection caused by the gas exhaled by the user entering the central tube 205.

[0051] Reference Figure 1 The detection system further includes: a sealing joint 202 and a joint switch, and the atomization cup 204 is connected to the central tube 205 through the sealing joint 202.

[0052] The signal processing device is used to detect whether the connector switch corresponding to the atomizer cup 204 is turned on;

[0053] If the connector switch is turned on, it is determined that the atomizer cup 204 is turned on.

[0054] The atomizer cup 204 is connected to the central tube 205 through the sealing joint 202, and the stimulant in the atomizer cup 204 is input into the central tube 205 through the sealing joint 202. A corresponding joint switch is provided on the sealing joint 202. When the detection has not started, the joint switch is not turned on, and the stimulant in the atomizer cup 204 cannot enter the central tube 205. When the detection starts, the joint switch is turned on, and the stimulant in the atomizer cup 204 can enter the central tube 205 through the sealing joint 202. The joint switch can be controlled to be turned on or off by a signal processing device.

[0055] This embodiment controls whether the stimulant in the atomizing cup 204 is injected into the concentrating tube 205 through the sealing joint 202 and the joint switch, so that the injection timing of the stimulant becomes controllable, thereby improving the accuracy of detection.

[0056] In one embodiment, there are multiple atomizer cups 204, and the concentration of the exciter in each atomizer cup 204 is different. The signal processing device is further used for:

[0057] According to a preset sequence, one of the plurality of atomization cups 204 is opened in turn, and the activator in the atomization cup 204 is input into the concentrating tube 205 .

[0058] like Figure 1 As shown, multiple atomization tubes can be arranged on both sides of the central tube 205, and each atomization tube can store an exciter. The concentration of the exciter in each atomization tube is different. During testing, the test is usually started from a low concentration.

[0059] At the beginning of the detection, the signal processing device first controls the first atomizer cup to open. After it is opened for a preset time, it controls the second atomizer cup to open, and so on. Before opening the second atomizer cup, the first atomizer cup is closed first to avoid mixing of the stimulants in the atomizer cups, which may lead to inaccurate detection results.

[0060] In one embodiment, the detection system includes an oral pressure tube 206 , and the oral pressure tube 206 is arranged at the entrance of the central tube 205 .

[0061] The signal processing device is further used to obtain the pressure at the inlet of the central pipe 205 through the outlet pressure pipe 206, and determine whether the pressure is greater than a preset pressure threshold;

[0062] If it is greater, it is determined that the pressure meets the first preset condition.

[0063] The oral pressure tube 206 is arranged at the entrance of the centralized tube 205 and is used to detect the pressure at the centralized entrance. When the entrance of the centralized tube 205 is not in use, the pressure is constant. When the user docks with the entrance of the centralized tube 205, pressure changes will occur. Therefore, by checking the pressure changes at the entrance of the centralized tube 205 through the oral pressure tube 206, it can be determined whether the user is docking with the entrance of the centralized tube 205, thereby determining the timing of starting the detection.

[0064] In one embodiment, there is at least one target atomization cup among the plurality of atomization cups 204 , and a relaxing agent is stored in the target atomization cup.

[0065] The signal processing device is also used to stop injecting the stimulant into the central tube 205 and inject the diastolic agent into the central tube 205 if the respiratory flow is abnormal.

[0066] Since there are many types of lung function diseases or respiratory abnormalities, such as asthma detection, at least one target nebulizer cup needs to be set in the nebulizer cup 204, and a dilator is stored in the target nebulizer cup. The dilator can dilate the bronchi. When the respiratory flow is abnormal, the signal processing device controls the target nebulizer cup storing the dilator to open, thereby eliminating the user's asthma symptoms.

[0067] Reference Figure 2 , Figure 2 A schematic structural diagram of a flow deviation device provided in this embodiment.

[0068] The bias flow device mainly includes a bias flow tube 201 , a negative pressure pump 211 and a flow valve 210 . The negative pressure pump 211 is connected to the bias flow tube 201 through the flow valve 210 , and the bias flow tube 201 is connected to the central pipe 205 .

[0069] The negative pressure pump 211 is used to start when the pressure meets a first preset condition.

[0070] The flow valve is used to adjust the pressure to a first flow rate when the pressure meets a first preset condition, so that the flow deviation device reaches the first power;

[0071] The flow valve is further used to adjust the flow rate to the second flow rate when the atomizer cup 204 is opened, so that the flow deviation device reaches the second power.

[0072] The negative pressure pump 211 is mainly connected to the inlet of the central tube 205 through the bias flow tube 201, and draws away the gas exhaled by the user through the inlet of the central tube 205. The extracted flow rate can be mainly controlled by the flow valve 210. The flow valve 210 can control the gas flow in the bias flow tube 201. By adjusting the flow valve 210, the gas flow extracted by the negative pressure pump 211 can be controlled. The flow valve 210 can be an electronic flow valve 210. Controlling the suction flow rate by the flow valve 210 is simpler and more accurate than adjusting the gear position of the negative pressure pump 211.

[0073] A filter 209 may be provided between the bias flow tube 201 and the flow valve 210. The filter 209 is mainly used to filter the gas exhaled by the user and part of the exciter, so as to avoid the pollution caused by the gas exhaled by the user and the exciter being directly discharged to the outside.

[0074] In this embodiment, a bias flow tube 201, a flow valve 210 and a negative pressure pump 211 are provided to extract the gas exhaled by the user at the entrance of the central tube 205 to prevent the gas exhaled by the user from entering the interior of the central tube 205 and causing cross infection. Moreover, the flow rate during extraction is adjusted by the flow valve 210, so that the flow rate during extraction can be made more accurate, which can not only accurately extract the gas exhaled by the user, but also minimize the extraction of the stimulant in the central tube 205, thereby ensuring that the detection can be carried out normally.

[0075] In one embodiment, the signal processing device is further used for:

[0076] determining whether the first flow rate is less than the respiratory flow rate;

[0077] If it is less than, the flow valve is adjusted from the first flow rate to be greater than or equal to the respiratory flow rate.

[0078] Since each person's respiratory data, such as respiratory flow, etc., may be different, when the user just docks with the centralized tube 205 interface, the first flow can be set through the flow valve 210, and the first flow can be slightly larger than the average respiratory flow, thereby ensuring that the gas exhaled by the user can be drawn away without causing a suffocation feeling to the user. After the user breathes for the first time, the user's respiratory flow can be detected. If the user's respiratory flow is still larger than the first flow, the first flow is adjusted through the flow valve 210 to be greater than or equal to the respiratory flow, thereby preventing the gas from entering the centralized tube 205 when the user exhales later.

[0079] This embodiment timely adjusts the first flow rate according to the user's respiratory flow rate, thereby ensuring that the gas exhaled by the user can be promptly pumped away by the negative pressure pump 211, thereby avoiding cross infection.

[0080] Reference Figure 3 The present application provides another structural schematic diagram of a detection system, including: a central tube 205, a pressure difference flow detection device 100, an atomizer cup 204, a bias flow device and a signal processing device, wherein the pressure difference flow detection device 100 is connected to the outlet of the central tube 205, the bias flow device and the atomizer cup 204 are respectively arranged in the middle of the central tube 205, and the distance between the bias flow device and the inlet of the central tube 205 is smaller than the distance between the atomizer cup 204 and the inlet of the central tube 205.

[0081] The detection system can also include a test bench 200. The concentrated pipe 205, the pressure difference flow detection device 100, the atomizer cup 204 and the bias flow device can all be arranged on the test bench 200. The test bench 200 can be mounted on the corresponding trolley 300. The trolley 300 can also be equipped with a display 301, a computer host 302, an oscillator 303, an oscillation tube 304, a pressure regulating valve 305 and a compressor box 306 and a series of test devices.
