[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] References to "one embodiment" or "some embodiments" etc. described in the present specification mean that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0050] It should be understood that the order of execution of the steps in the following embodiments does not imply a precedence of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0051] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0052] In the biomedical field, it is often necessary to insert detection instruments or medical instruments into the trachea of ​​relevant personnel and relevant experimental subjects, such as collecting relevant data in the airway of relevant personnel and relevant experimental subjects, or performing medical-related auxiliary operations. In this process, since the airway is difficult to visualize, it is usually difficult to accurately and quickly find the airway opening, making it difficult to insert relevant instruments, resulting in low efficiency and success rate of instrument insertion.

[0053] For example, during the endotracheal intubation process, there may be a large amount of secretions in the oral cavity of the intubated subject, such as active bleeding in the oropharynx and a large amount of vomit in the oropharynx. These secretions are not easy to clean up in a short period of time. In addition, some intubated subjects may have congenital or acquired factors that cause abnormal throat shape and poor exposure of the airway opening, making it difficult for the intubator to find the airway opening accurately and quickly, making it difficult or taking a long time to insert the endotracheal tube, resulting in low intubation efficiency and success rate.

[0054] In order to accurately and quickly find the airway opening and improve the efficiency and success rate of instrument placement, the embodiment of the present application provides an airway opening detection system and method. After the gas detection device is inserted into the throat of the object to be detected, the system and method detects the gas flow rate at different positions in the throat through the gas detection device to obtain the gas flow rate at different positions in the throat, and then the data processing device is configured to display the gas flow rate at different positions on the interface, and according to the gas flow rate at different positions, the position of the airway opening of the object to be detected is determined and highlighted. This solution can quickly and accurately determine the position of the airway opening, so that the user can conveniently perform the placement operation of the relevant instrument under the guidance of the gas detection device, thereby improving the efficiency and success rate of instrument placement.

[0055] In order to facilitate further understanding of the technical solutions in some embodiments of the present application, the technical solutions of the airway opening detection system and method, as well as how the technical solutions solve the above-mentioned technical problems are described in detail below in combination with some specific embodiments and drawings. The various embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Obviously, the described embodiments are part of the embodiments of the present application, not all of them.

[0056] The airway opening detection method provided by the embodiment of the present invention can be applied in Figure 1 In the airway opening detection system shown, the airway opening detection system includes a gas detection device and a data processing device, wherein the data processing device includes a display and a control device. The gas detection device communicates with the control device of the data processing device through a cable or a network.

[0057] The gas detection device can be inserted into the throat of the object to be detected, and is used to detect the gas flow rate at different positions in the throat, obtain the gas flow rate at different positions in the throat and send it. The control device of the data processing device is configured to: receive the gas flow rate at different positions detected by the gas detection device, and control the display to display the gas flow rate at different positions on the interface; determine the airway opening position according to the gas flow rate at different positions, and control the display to highlight the airway opening position.

[0058] In actual application, Figure 2 As shown, when the object to be detected (living body) inhales and exhales, the gas at the airway opening is inhaled or exhaled with the action of inhalation and exhalation, forming a flow rate difference of inhalation or exhalation. The gas detection device can detect the flow rate difference of the exhaled gas of the object to be detected; the user extends the gas detection device into the throat of the object to be detected, and can control the movement of the gas detection device. After each movement and stop, the gas detection device detects the gas flow rate at the current position and sends the gas flow rate at this position to the data processing device. The control device of the data processing device receives the gas flow rate at the current position sent by the gas detection device in real time, and displays the gas flow rate at this position in real time through the display. The gas flow rate at the real-time position of the throat is shown in FIG. Figure 3 As shown, Figure 3 The gas flow rate at the position is 4cm / s for exhalation and -4cm / s for inhalation. During operation, the gas detection device continues to detect the gas flow rate at the gas position and sends it to the data processing device; the control device of the data processing device receives the gas flow rate at the current position for display and recording, and the gas flow rate at different positions can be displayed on the display interface of the display. The gas flow rate at different positions of the throat is as follows: Figure 4 shown. Figure 4 The gas flow rates at different positions around the airway opening (i.e. other positions with a flow rate of 4 cm / s) are represented, including 0 cm / s, 2 cm / s, -2 cm / s, 3 cm / s and other gas flow rates for exhalation (positive values) or inhalation (negative values). The gas flow rates at different positions are displayed on the display interface of the display, so that the user can observe the gas flow rates at different positions in the throat in real time through the display interface of the display. After obtaining the gas flow rates at the preset positions, the data processing device can determine the airway opening according to the gas flow rates at the preset positions, and when determining the position of the airway opening, the airway opening position can be mechanically highlighted on the display interface, such as a highlighted flashing display, and can also be accompanied by a voice reminder.

[0059] In this embodiment, the gas detection device is inserted into the throat of the object to be detected, and the gas flow rate at different positions in the throat can be detected by the gas detection device. The gas flow rate at different positions is then displayed on the display of the data processing device. Then, according to the gas flow rate at different positions, the position of the airway opening of the object to be detected is determined and highlighted. The position of the airway opening can be determined quickly and accurately, so that the user can conveniently perform the insertion operation of relevant instruments under the guidance of the gas detection device, thereby improving the efficiency and success rate of instrument insertion.

[0060] The data processing device provided in the embodiments of the present application may have various implementation forms. For example, the data processing device may include but is not limited to various personal computers, laptops, smart phones, tablet computers, and portable wearable devices.

[0061] In some embodiments, the gas detection device includes an ultrasonic flow velocity measurement structure and a signal sending device that are interconnected, and one end of the ultrasonic flow velocity measurement structure can be extended into the throat of the object to be detected. The ultrasonic flow velocity measurement structure is used to send an ultrasonic signal to the detection position of the throat, receive the ultrasonic signal reflected at the detection position, and determine the gas flow velocity at the detection position based on the transmitted and received ultrasonic signals. The signal sending device is used to send the gas flow velocity at the detection position detected by the ultrasonic flow velocity measurement structure to a data processing device to obtain the gas flow velocity at different positions. The signal sending device can be Bluetooth.

[0062] It should be understood that when a living body breathes, gas enters the airway from the airway opening and flows out from the airway opening to the throat. During this process, the airflow velocity at the airway opening changes most significantly. The ultrasonic flow velocity measurement structure can send a high-frequency ultrasonic signal into the fluid in the throat of the object to be detected. The gas particles in the fluid in the throat will produce a frequency shift on the ultrasonic signal. This frequency shift is called Doppler shift, which is proportional to the speed of the gas particles in the throat in the fluid. The ultrasonic flow velocity measurement structure can measure this Doppler shift based on the ultrasonic signal reflected from the process, that is, the gas flow velocity at a specified position in the throat can be measured by using the change in the propagation velocity of the ultrasonic wave with the change in the flow velocity. The resolution can reach 1mm / s, and the flow velocity of small flow gas and bidirectional gas flow can be measured; the subsequent data processing device can accurately determine the position of the airway outlet according to the change in the gas flow velocity at different positions in the throat.

[0063] In this embodiment, the ultrasonic flow rate measurement structure sends an ultrasonic signal to the detection position of the throat, receives the ultrasonic signal reflected at the detection position, and determines the gas flow rate at the detection position based on the transmitted and received ultrasonic signals, and then sends it to the data processing device through the signal sending device to determine the position of the airway opening according to the gas flow rate at different positions. High-precision measurement of gas flow rate can be achieved through the propagation time difference or Doppler effect of the ultrasonic signal. Compared with the traditional mechanical flow rate detection method, ultrasonic measurement is more sensitive to small flow rate changes, suitable for accurate detection in complex environments, and has higher accuracy in gas flow rate detection, which improves the accuracy of airway opening position detection.

[0064] In some embodiments, Figure 5 As shown, the ultrasonic flow velocity measurement structure includes an ultrasonic flow meter and an ultrasonic transmission component; the signal sending device is electrically connected to the ultrasonic flow meter. One end of the ultrasonic transmission component is connected to the ultrasonic flow meter, and the other end can be extended into the throat of the object to be detected. The ultrasonic transmission component is used to transmit ultrasonic signals. The ultrasonic flow meter is used to send ultrasonic signals to the detection position of the throat through the ultrasonic transmission component, and receive the ultrasonic signals reflected at the detection position through the ultrasonic transmission component, and determine the gas flow rate at the detection position according to the transmitted and received ultrasonic signals. The ultrasonic transmission component is a structure made of metal material.

[0065] In actual use, when the user needs to detect the airway opening, the user extends one end of the ultrasonic transmission component into the throat of the object to be detected, and the gas detection device starts the gas flow rate detection of the current position of the throat, and sends the detected gas flow rate to the control device of the data processing device. In other flow rate detection processes, the ultrasonic flowmeter emits an ultrasonic signal, and the ultrasonic transmission component transmits the emitted ultrasonic signal to the end extending into the throat, and sends it to the fluid at the throat position (i.e., the detection position) where the end is located. After the ultrasonic signal is reflected by the fluid at the detection position, it is transmitted and fed back to the ultrasonic flowmeter through the ultrasonic transmission component. The ultrasonic flowmeter determines the gas flow rate of the fluid at the detection position based on the time difference between the emission and reception of the ultrasonic signal, and sends it to the control device of the data processing device through a signal sending device (such as Bluetooth). Then, the user controls one end of the ultrasonic transmission component to move the position, and the ultrasonic flowmeter continues to detect the gas flow rate at the next position and sends it. The control device determines the change of the gas flow rate at the throat according to the gas flow rates at different positions, determines the position of the airway opening and gives a prompt. After knowing the location of the airway opening, the user controls the end of the ultrasonic transmission component that extends into the throat to stop at the airway opening, and extends the instrument to be inserted (such as an endotracheal tube) into the throat along the extension direction of the ultrasonic transmission component. The user can then smoothly and accurately reach and pass through the airway opening, and insert the instrument to be inserted into the airway with high accuracy.

[0066] In some embodiments, during the operation of the ultrasonic flow meter, the ultrasonic flow meter uses a pulsed mode to send ultrasonic signals, that is, within a single detection time (i.e., the time from the emission of an ultrasonic wave to the detection of the gas flow rate), the ultrasonic signal is emitted once and then stops, waiting to receive the ultrasonic signal reflected back from the ultrasonic transmission component. This method can reduce the signal transmission disorder caused by the continuous emission of ultrasonic signals and the interference of other ultrasonic waves, and improve the accuracy of the detected gas flow rate.

[0067] In this embodiment, since the ultrasonic transmission component only needs to be inserted into the throat to complete ultrasonic signal transmission and reflection detection, it avoids interference from structures or sensors that are in direct contact with the gas flow, has little effect on the original state of the gas flow, and ensures the authenticity of the measurement results; real-time detection of the dynamic changes in the gas flow rate can reflect the instantaneous characteristics of the airflow in the throat. In addition, through the ultrasonic transmission component, the gas detection device can adapt to throat structures of different shapes or sizes without complex adjustments for individuals, which improves the versatility and ease of use of the equipment; since ultrasonic measurement does not require complex mechanical parts to directly participate in fluid detection, the system runs stably and is highly durable, and the ultrasonic signal is harmless to human tissue and has good biosafety.

[0068] In some embodiments, the user can pre-set different detection modes for the gas detection device. Different detection modes can adapt to the breathing conditions of different objects to be detected (such as different breathing frequencies or exhaled air flows), and different detection modes have different single detection durations. For example, the time for a normal ordinary life form to exhale (or inhale) once is 1s, and detection mode A can adapt to the breathing conditions of normal ordinary life forms, and its single detection duration at a single position can be 1s; the time for some life forms with rapid exhalation to exhale (or inhale) once is less than 1s, and detection mode B can adapt to the breathing conditions of life forms with rapid exhalation, and its single detection duration at a single position can be less than 1s, such as 0.5s. In actual use, the user can select a suitable detection mode according to the breathing conditions of the object to be detected. After the gas detection device is started, the ultrasonic flowmeter detects the gas flow rate in the throat of the object to be detected according to the selected detection mode, thereby detecting the gas flow rate at different positions.

[0069] In this embodiment, by setting different detection modes for the gas detection device, the gas detection device can perform gas flow rate detection according to different detection modes, can adapt to the breathing conditions of different objects to be detected, improves the accuracy of gas flow rate detection, and introduces improved accuracy of airway opening position.

[0070] In some embodiments, a mode switch for selecting a detection mode may be provided on the gas detection device (such as an ultrasonic flow meter). When using the gas detection device, the user selects a suitable detection mode according to the actual exhalation condition of the object to be detected, so that the ultrasonic flow meter performs detection work according to the selected detection mode. In other embodiments, in order to reduce the structure of the gas detection device, a mode selection control may be provided on the display of the data processing device. When the user uses the gas detection device to detect the gas flow rate, the user selects the detection mode through the mode selection control provided on the display. The control device sends the detection mode selected by the user to the ultrasonic flow meter through the signal sending device, so that the ultrasonic flow meter performs detection work according to the selected detection mode.

[0071] In some embodiments, Figure 6 As shown, the ultrasonic transmission component includes a metal ultrasonic guide core and a fiber structure wrapped around the metal ultrasonic guide core, wherein one end of the metal ultrasonic guide core can be exposed to the outside air. The metal material has good sound wave conduction performance, and the metal ultrasonic guide core can effectively reduce the energy loss of the ultrasonic signal during the transmission process, thereby improving the transmission efficiency and stability of the signal. The fiber structure wrapped around the metal ultrasonic guide core provides good mechanical protection and external interference isolation, thereby avoiding signal distortion or attenuation caused by contact with the external environment or throat tissue; the fiber structure can also buffer the impact of external vibration or impact on the metal ultrasonic guide core, thereby ensuring the stability of signal transmission and the durability of the device.

[0072] In some embodiments, the metal ultrasonic waveguide core and the fiber structure can be made of corrosion-resistant and anti-pollution materials, so that both can maintain long-term stable performance in a humid, acidic and alkaline throat environment. The fiber structure can be made of flexible and biocompatible materials to reduce the stimulation of tissues when the detection device is inserted into the throat, thereby improving the comfort and safety of the patient. For example, the metal ultrasonic waveguide core can be an aluminum alloy ultrasonic waveguide core, and the fiber structure can be a polystyrene fiber structure.

[0073] In some embodiments, Figure 6 As shown, the end of the fiber structure away from the ultrasonic flow meter is provided with multiple vents for the metal ultrasonic guide core to ventilate the outside. The vents allow gas to pass freely through the component, thereby forming a natural airflow environment in the detection area, while ensuring that the measured gas flow rate is consistent with the actual state, so that the metal ultrasonic guide core can efficiently transmit signals, avoiding the restriction or turbulence of gas flow caused by the obstruction of the ultrasonic transmission component, and ensuring that the measured flow rate data has good real-time performance. The design of the vents ensures internal gas circulation and reduces the accumulation of foreign matter. At the same time, the surface of the component is easy to clean and disinfect, which increases the service life of the equipment.

[0074] In the above scheme, through the combined design of metal ultrasonic guide core, fiber structure and vents, while ensuring the efficient transmission of ultrasonic signals, the safety, durability and applicability of the detection device are optimized, and the accuracy and reliability of gas flow rate detection in the throat area are significantly improved.

[0075] In some embodiments, the gas detection device further includes a control box, in which a signal sending device, an ultrasonic flow meter, and a control switch of the gas detection device are installed, and the control switch is used to start and stop the gas detection device. The control switch provides an intuitive start and stop operation function, simplifies the complex equipment control process, and enables users to quickly get started, which is particularly suitable for high-frequency and fast operation scenarios in clinical applications. In addition, the control switch can quickly start and stop the device to ensure that the device can be quickly shut down in an emergency (such as patient discomfort or equipment abnormality) to avoid further stimulation or damage to the patient; the control function is concentrated on the control box, which reduces the possibility of false triggering and improves the safety and reliability of the equipment operation. In some embodiments, the control switch can be expanded to multiple modes (such as manual start and stop, timing control, or remote start) to meet the needs of different application scenarios (such as hospitals, laboratories, or home monitoring).

[0076] In this solution, the control box can protect the internal core components (signal sending device and ultrasonic flow meter) from external environmental interference, such as moisture, dust or mechanical shock, and extend the life of the equipment. The signal sending device, ultrasonic flow meter and control switch are concentrated in the control box, making the entire gas detection device more compact and integrated, and easy to install and maintain.

[0077] In some embodiments, the control box is provided with a mounting port for mounting the ultrasonic transmission component, and the ultrasonic transmission component is detachably mounted on the control box through the mounting port. In actual use, when the user needs to perform airway opening detection, the user installs the ultrasonic transmission component on the control box to obtain a complete gas detection device. The user extends one end of the ultrasonic transmission component in the gas detection device into the throat of the object to be detected, starts the control switch to control the gas detection device to detect the gas flow rate at different positions of the throat, and the gas detection device sends the detected gas flow rate to the control device of the data processing device. The user controls one end of the ultrasonic transmission component to move the position, continues to detect the gas flow rate at the next position and sends it, and the control device determines the change of the gas flow rate in the throat according to the gas flow rate at different positions, determines the position of the airway opening and gives a prompt. After knowing the position of the airway opening, the user controls the end of the ultrasonic transmission component that extends into the throat to stop at the airway opening, removes the control box, and extends the instrument to be inserted (such as an endotracheal tube) into the throat along the extension direction of the ultrasonic transmission component. The instrument can smoothly and accurately reach and pass through the airway opening, and insert the instrument to be inserted into the airway with high accuracy. Since the metal ultrasonic guide core and fiber structure of the ultrasonic transmission component are both flexible materials, the patient's comfort and safety can be improved.

[0078] In some embodiments, the control box may be provided with a heat dissipation structure or a sealed box made of high heat-resistant material to avoid overheating caused by long-term operation of the device and ensure stable operation of the detection device. The control box is provided with reserved space and interfaces for new functional modules (such as carbon dioxide sensors, wireless transmission modules, power management modules or data storage modules) to facilitate future functional upgrades and expansions of the device.

[0079] In some embodiments, the control device is specifically configured to: determine the airway opening position according to the size of the gas flow rate at different positions, wherein the airway opening position is the position with the largest gas flow rate. That is, the control device determines the position with the largest gas flow rate among the gas flow rates at different positions as the airway opening position. The closer to the airway opening, the greater the gas flow rate, and the position with the largest gas flow rate is determined as the airway opening position, which is more accurate.

[0080] In some embodiments, a gas detection device (i.e., an ultrasonic flow rate measurement structure) detects the exhaled gas flow rate and the inhaled gas flow rate at the same position in the throat area within a preset time period (e.g., within 1 s), obtains the exhaled gas flow rate and the inhaled gas flow rate at the same position in the throat area, and uses the exhaled gas flow rate and the inhaled gas flow rate at the position as the gas flow rate at the position, and sends them to a data processing device through a signal sending device.

[0081] That is, the gas flow rate at each position includes the expiratory gas flow rate (positive value) and the inspiratory gas flow rate (negative value) at that position; the control device determines the position of the airway opening according to the size of the gas flow rate at different positions, and is configured to: determine the difference between the expiratory gas flow rate and the inspiratory gas flow rate in the gas flow rate at the same position, and obtain the gas flow rate difference at different positions; determine the position with the largest gas flow rate difference as the airway opening position, which is more accurate.

[0082] It is important to understand that the gas detection device (that is, the ultrasonic flow velocity measurement structure) can measure the gas flow velocity at different locations in the throat, and the gas detection device can detect the gas flow velocity when the living body exhales and inhales. The gas flow direction is different. The gas flow velocity is positive when exhaling and negative when inhaling. If only the size of the gas flow velocity is judged, it is easy to make a wrong judgment.

[0083] In this embodiment, the gas flow rate at each position includes the expiratory gas flow rate and the inhalation gas flow rate at that position. The control device determines the difference between the expiratory gas flow rate and the inhalation gas flow rate in the gas flow rate at the same position to obtain the gas flow rate difference at different positions; the position with the largest gas flow rate difference is determined as the airway opening position, and the obtained airway opening position has higher accuracy.

[0084] In some embodiments, the gas detection device is also used to detect the carbon dioxide concentration at different positions in the throat area to obtain the carbon dioxide concentration at different positions. The control device is also configured to: receive the gas flow rate and carbon dioxide concentration at different positions in the throat area sent by the gas detection device, and control the display to display the gas flow rate and carbon dioxide concentration at different positions on the interface, and simultaneously display the distribution data of the gas flow rate and carbon dioxide concentration at different positions on the display interface of the control display, and can present the detailed conditions in the airway through color graphics, curves or 3D graphics, which is convenient for users to interpret; according to the gas flow rate and carbon dioxide concentration at different positions, determine the airway opening position of the object to be detected, and control the display to highlight the airway opening position.

[0085] It is important to understand that the distribution of carbon dioxide concentration at different locations can reflect the efficiency of gas exchange in the airway and provide data support for evaluating respiratory system function. In cases of airway obstruction or stenosis, the gas flow rate distribution may be abnormal, and the carbon dioxide concentration will increase abnormally due to restricted gas exchange. Real-time monitoring of the dynamic changes in gas flow rate and carbon dioxide concentration in the throat can better reflect the instantaneous state of airway function.

[0086] In this embodiment, the gas flow rate and carbon dioxide concentration at different positions of the throat are simultaneously detected by the gas detection device, providing multi-dimensional airway dynamic information, which is helpful to more accurately evaluate the airway function and status. According to the gas flow rate and carbon dioxide concentration at different positions, the position of the airway opening of the object to be detected is determined and highlighted. Through the comprehensive analysis of the flow rate and carbon dioxide concentration, the airway opening can be located more efficiently and accurately, reducing misjudgment; accurate airway opening positioning and status assessment provide strong support for endotracheal intubation, bronchoscopy or other instrument insertion operations.

[0087] In some embodiments, the gas detection device further includes a carbon dioxide sensor (not shown). The carbon dioxide sensor is electrically connected to the signal sending device. The carbon dioxide sensor is installed at one end of the ultrasonic transmission assembly away from the ultrasonic flow meter, and is used to detect the carbon dioxide concentration at the detection position of the throat. The signal sending device is also used to send the carbon dioxide concentration at the detection position detected by the carbon dioxide sensor to the data processing device to obtain the carbon dioxide concentration at different positions of the throat.

[0088] In some embodiments, the control device determines the airway opening position of the object to be detected according to the gas flow rate and carbon dioxide concentration at different positions, and is configured as follows: determining the gas flow rate difference at different positions according to the gas flow rate at different positions, determining the first position with the largest gas flow rate difference; determining the second position with the largest carbon dioxide concentration among the carbon dioxide concentrations at different positions; if the first position and the second position are the same position, determining the first position or the second position as the airway opening position; if the first position and the second position are different positions, determining the first position as the airway opening position. The position with the largest gas flow rate difference and the largest carbon dioxide concentration as the airway opening position has higher accuracy.

[0089] In some embodiments, if the first position and the second position are different positions, a curve of the gas flow rate difference versus position is drawn according to the gas flow rate difference at different positions to obtain a gas flow rate curve, and a curve of the carbon dioxide concentration versus position is drawn according to the carbon dioxide concentration at different positions to obtain a carbon dioxide concentration curve, the gas flow rate curve and the carbon dioxide concentration curve are cross-compared to determine the peak overlapping area in the gas flow rate curve and the carbon dioxide concentration curve, and the position corresponding to the peak overlapping area is determined as the airway opening position, which can accurately determine the airway opening position, and highlight the airway opening position through the display, thereby improving data visualization and user experience.

[0090] In some embodiments, Figure 7 As shown, a method for detecting an airway opening is provided, and the airway opening detection is performed using the above-mentioned airway opening detection system. The method is applied in Figure 1 The control device of the data processing device is taken as an example to illustrate, which includes the following steps:

[0091] S10: receiving the gas flow rates at different positions detected by the gas detection device, and controlling the display to display the gas flow rates at different positions on an interface.

[0092] After the data processing device is started, the control device receives the gas flow rates at different positions detected by the gas detection device, and controls the display to display the gas flow rates at different positions on the interface. The gas detection device can be inserted into the throat of the object to be detected, and is used to detect the gas flow rates at different positions in the throat, obtain the gas flow rates at different positions in the throat, and send them.

[0093] The specific structure and working process of the gas detection device are mentioned above and will not be repeated here.

[0094] S20: determining the position of the airway opening according to the gas flow rate at different positions, and controlling the display to highlight the position of the airway opening.

[0095] The control device determines the position of the airway opening according to the gas flow rate at different positions, and controls the display to highlight the position of the airway opening.

[0096] Among them, the airway opening position is determined according to the size of the gas flow rate at different positions, wherein the airway opening position is the position with the largest gas flow rate. That is, the control device determines the position with the largest gas flow rate among the gas flow rates at different positions as the airway opening position. The closer to the airway opening position, the greater the gas flow rate, and the position with the largest gas flow rate is determined as the airway opening position, which is more accurate.

[0097] In this embodiment, the gas detection device is inserted into the throat of the object to be detected, and the gas flow rate at different positions in the throat can be detected by the gas detection device. The gas flow rate at different positions is then displayed on the display interface, and then the position of the airway opening of the object to be detected is determined and highlighted according to the gas flow rate at different positions. The position of the airway opening can be determined quickly and accurately, so that the user can conveniently perform the insertion operation of relevant instruments under the guidance of the gas detection device, thereby improving the efficiency and success rate of instrument insertion.

[0098] In some embodiments, the gas flow rate at each position includes the exhaled gas flow rate (positive value) and the inhaled gas flow rate (negative value) at the position. In step S20, the airway opening position is determined according to the gas flow rates at different positions, and the display is controlled to highlight the airway opening position, which specifically includes the following steps:

[0099] S201: Determine the difference between the exhaled gas flow rate and the inhaled gas flow rate in the gas flow rate at the same position, and obtain the gas flow rate difference at different positions.

[0100] S202: Determine the position where the gas flow rate difference is the largest as the airway opening position, and control the display to highlight the airway opening position.

[0101] It is important to understand that the gas detection device (that is, the ultrasonic flow velocity measurement structure) can measure the gas flow velocity at different locations in the throat, and the gas detection device can detect the gas flow velocity when the living body exhales and inhales. The gas flow direction is different. The gas flow velocity is positive when exhaling and negative when inhaling. If only the size of the gas flow velocity is judged, it is easy to make a wrong judgment.

[0102] In this regard, after obtaining the gas flow rates at different positions, the control device determines the difference between the expiratory gas flow rate and the inhaled gas flow rate in the gas flow rate at the same position, obtains the gas flow rate difference at different positions, and determines the position with the largest gas flow rate difference as the airway opening position, and controls the display to highlight the airway opening position.

[0103] For example, the gas flow rate at a certain position A includes the expiratory gas flow rate of 4 cm / s and the inspiratory gas flow rate of -4 cm / s at the position, then it is determined that the difference between the expiratory gas flow rate and the inspiratory gas flow rate at the gas flow rate at the position A is 8 cm / s, that is, the gas flow rate difference at the position A is 8 cm / s; the gas flow rate differences at other multiple positions are 0 cm / s, 2 cm / s, 4 cm / s, 5 cm / s, and 6 cm / s, respectively, then it is determined that the gas flow rate difference at position A is the largest, and the position A is the airway opening position, then the control display is used to highlight the airway opening position, such as highlighting and flashing the dot at position A.

[0104] In this embodiment, the gas flow rate at each position includes the expiratory gas flow rate and the inhalation gas flow rate at that position. The control device determines the difference between the expiratory gas flow rate and the inhalation gas flow rate in the gas flow rate at the same position to obtain the gas flow rate difference at different positions; the position with the largest gas flow rate difference is determined as the airway opening position, and the obtained airway opening position has higher accuracy.

[0105] In some embodiments, the gas detection device is also used to detect the carbon dioxide concentration at different positions in the throat to obtain the carbon dioxide concentration at different positions. In step S20, the airway opening position is determined according to the gas flow rate at different positions, and the display is controlled to highlight the airway opening position, which specifically includes the following steps:

[0106] S21: receiving the gas flow rate and carbon dioxide concentration at different positions in the throat area sent by the gas detection device, and controlling the display to display the gas flow rate and carbon dioxide concentration at different positions on the interface.

[0107] In this embodiment, the body detection device is used to detect the gas flow rate and carbon dioxide concentration at different positions in the throat area, obtain the gas flow rate and carbon dioxide concentration at different positions, and send them to the data processing device.

[0108] The control device of the data processing device receives the gas flow rate and carbon dioxide concentration at different positions in the throat area sent by the gas detection device, and controls the display to display the gas flow rate and carbon dioxide concentration at different positions on the interface. The distribution data of the gas flow rate and carbon dioxide concentration at different positions can be displayed on the display interface of the display at the same time, and the detailed conditions in the airway can be presented through color graphics, curves or 3D graphics, which is convenient for users to interpret.

[0109] S22: Determine the position of the airway opening of the object to be detected according to the gas flow rate and carbon dioxide concentration at different positions, and control the display to highlight the position of the airway opening.

[0110] Then, the control device determines the position of the airway opening of the object to be detected according to the gas flow rate and carbon dioxide concentration at different positions, and controls the display to highlight the position of the airway opening.

[0111] It is important to understand that the distribution of carbon dioxide concentration at different locations can reflect the efficiency of gas exchange in the airway and provide data support for evaluating respiratory system function. In cases of airway obstruction or stenosis, the gas flow rate distribution may be abnormal, and the carbon dioxide concentration will increase abnormally due to restricted gas exchange. Real-time monitoring of the dynamic changes in gas flow rate and carbon dioxide concentration in the throat can better reflect the instantaneous state of airway function.

[0112] In this embodiment, the gas flow rate and carbon dioxide concentration at different positions of the throat are simultaneously detected by the gas detection device, providing multi-dimensional airway dynamic information, which is helpful to more accurately evaluate the airway function and status. According to the gas flow rate and carbon dioxide concentration at different positions, the position of the airway opening of the object to be detected is determined and highlighted. Through the comprehensive analysis of the flow rate and carbon dioxide concentration, the airway opening can be located more efficiently and accurately, reducing misjudgment; accurate airway opening positioning and status evaluation provide strong support for intubation, bronchoscopy or other instrument insertion operations.

[0113] In some embodiments, step S22, i.e., determining the airway opening position of the object to be detected according to the gas flow rate and carbon dioxide concentration at different positions, specifically includes the following steps:

[0114] S221: determining the difference of gas flow velocities at different positions according to the gas flow velocities at different positions, and determining a first position where the difference of gas flow velocities is the largest;

[0115] S222: Determine a second location with the highest carbon dioxide concentration among carbon dioxide concentrations at different locations;

[0116] S223: If the first position and the second position are the same position, determine that the first position or the second position is the airway opening position.

[0117] In this embodiment, the gas flow rate difference at different positions is determined according to the gas flow rate at different positions, and the first position with the largest gas flow rate difference is determined; the second position with the largest carbon dioxide concentration among the carbon dioxide concentrations at different positions is determined; if the first position and the second position are the same position, the first position or the second position is determined to be the airway opening position; if the first position and the second position are different positions, the first position is determined to be the airway opening position. The position with the largest gas flow rate difference and the largest carbon dioxide concentration is used as the airway opening position, which has higher accuracy.

[0118] In some embodiments, if the first position and the second position are different positions, a curve of the gas flow rate difference versus position is drawn according to the gas flow rate difference at different positions to obtain a gas flow rate curve, and a curve of the carbon dioxide concentration versus position is drawn according to the carbon dioxide concentration at different positions to obtain a carbon dioxide concentration curve, the gas flow rate curve and the carbon dioxide concentration curve are cross-compared to determine the peak overlapping area in the gas flow rate curve and the carbon dioxide concentration curve, and the position corresponding to the peak overlapping area is determined as the airway opening position, so as to accurately determine the airway opening.
