[0046] In order to make the objects, technical solutions and advantages of the present application clearer and more apparent, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0047] At present, in clinical use, tracheal intubation is widely used in surgical anesthesia, intensive care and rescue. The pressure of the intubation balloon needs to be maintained in an appropriate range (usually 20-30cmH2O), which is too high and may compress the tracheal mucosa, leading to ischemic necrosis; too low may cause air leakage and aspiration. However, the clinical still mainly relies on artificial intermittent use of balloon pressure gauge detection, which has the problems of discontinuity, hysteresis and human error.

[0048] In addition, the change of the patient's airway temperature reflects the state of the respiratory system and the body temperature regulation, which is also important for the monitoring of critically ill patients. However, the prior art does not integrate these two functions into an integrated module of an electrocardiographic monitoring system.

[0049] To solve the above problems, the present application provides an integrated display method of balloon pressure and airway temperature based on an electrocardiographic monitor, which relates to the technical field of medical devices, and a modular device integrated into an electrocardiographic monitoring system is provided, which has the function of automatically detecting and maintaining the pressure of the tracheal intubation balloon, and can monitor the airway temperature in real time, and can integrate and display the patient's condition, so that the staff can clearly know the patient's condition and automatically adjust the abnormal situation, effectively ensuring the life and health of the patient.

[0050] The integrated display method of balloon pressure and airway temperature based on an electrocardiographic monitor according to the preferred embodiment of the present application, as shown in Figure 1 The integrated display method of balloon pressure and airway temperature based on an electrocardiographic monitor includes the following steps:

[0051] Step S10, obtaining the original pressure data of the balloon in the patient's tracheal intubation and the original temperature data of the airway, and preprocessing the original pressure data of the balloon and the original temperature data of the airway to obtain target pressure data and target airway data. The preprocessing includes first preprocessing of the original pressure data of the balloon and second preprocessing of the original temperature data of the airway; the first preprocessing is analog-digital conversion processing, and the second preprocessing is voltage signal conversion processing, analog-digital conversion processing, filtering processing and outlier rejection processing.

[0052] Artificial airway is often involved in the process of ventilator therapy, and tracheal intubation is the core medical device of artificial airway. The tracheal intubation is a method of placing a specially designed endotracheal tube through the mouth or nose, passing through the glottis and placing it into the trachea or bronchus, which provides the best conditions for airway patency, ventilation and oxygen supply, and respiratory tract suction, and is an important measure to rescue patients with respiratory dysfunction. The tracheal intubation generally has an airbag for airway sealing. The airbag is an airbag device on the intubation tube, and the airbag pressure needs to be set in a certain range, and the existing technology is generally preferred to be set to 20-30cmH2O water column. The traditional method for monitoring the airbag pressure in the past is to directly use a syringe or a manual pressure gauge for inflation, which cannot accurately monitor and control the pressure, and the airbag pressure that is too high or too low will cause patient safety problems.

[0053] As shown in Figure 2 , the present application adopts a universal plug-in structure, which can be seamlessly integrated into the existing electrocardiograph monitoring system (i.e. a modular device that can be directly installed on the electrocardiograph monitoring system) as an additional module (i.e. an airbag pressure monitoring module and an airway temperature monitoring module in Figure 2 , and has the following functions: 1. Support data interface docking with the host system, such as RS-485 (RS-485 interface is a standard that defines the electrical characteristics of drivers and receivers in a balanced digital multipoint system. RS-485 interface belongs to wired transmission, so it needs hardware transmission medium), USB, or wireless communication (BLE, Bluetooth Low Energy technology); 2. Small device size, convenient for bedside use, suitable for ICU, operating room and emergency department and other scenes.

[0054] The present application has airbag pressure detection and automatic maintenance function, and the steps to realize this function are as follows: 1. Using a micro pressure sensor and an automatic air pressure adjusting mechanism (such as a micro pump or an electromagnetic valve), the airbag pressure of the tracheal intubation is monitored and automatically adjusted in real time, and maintained within the set safe range; 2. Support continuous monitoring and alarm function to prevent airbag pressure from being too high or too low; 3. All data can be uploaded to the electrocardiograph monitoring system interface for unified observation by medical staff.

[0055] The present application also has airway temperature real-time monitoring function, and the steps to realize this function are as follows: 1. The temperature change of air flow is monitored by embedding a thermal probe into the airway; 2. The data is synchronously uploaded to the monitoring instrument interface to provide a temperature trend curve for evaluating the patient's respiratory and body temperature conditions.

[0056] Specifically, the air guide tube is connected with the tracheal intubation tube of the patient to obtain a closed air guide path; a micro pressure sensor is embedded in the closed air guide path, and the micro pressure sensor is used to collect original pressure data of the air bag in the closed air guide path at a first preset frequency; and the original pressure data of the air bag is subjected to analog-digital conversion processing to obtain target pressure data.

[0057] The application is a closed-loop automatic control structure, which first monitors the pressure of the air bag. The monitoring process of the pressure of the air bag is as follows: 1. air bag connection: a module is connected with the air bag of the tracheal intubation tube in the patient's body through an air guide tube to form a closed path (i.e. the closed air guide path in the application); 2. real-time collection by a micro pressure sensor (MEMS, Micro Electro Mechanical Systems): a micro pressure sensor (such as based on the silicon piezoresistance principle) embedded in the closed air guide path collects the pressure value inside the air bag (i.e. the original pressure data of the air bag in the application) in real time, and the unit is cmH2O; 3. high-frequency sampling: the sensor continuously samples at a frequency higher than 1 Hz (such as 1-10 Hz), ensuring no delay in reading; 4. data transmission and signal conditioning: the original data are transmitted to the main control unit (MCU or embedded chip) after being processed by an analog-digital conversion module (ADC, Analog-to-Digital Conversion, which is a technology for converting an analog signal into a digital signal. In the analog-digital conversion process, the original data are first sampled by a sampling and holding circuit, and then converted into a digital signal through a quantization and coding process, which usually involves converting the amplitude of an analog signal into a digital code for processing and storage by a computer or other digital system) (to obtain target pressure data); 5. intelligent judgment logic: the application sets a safe pressure interval (i.e. the preset safe pressure interval in the application, which is preferably set to 20-30 cmH2O); if the current pressure (i.e. the target pressure data in the application) is higher than the upper limit (i.e. the second preset pressure threshold in the application) or lower than the lower limit (i.e. the first preset pressure threshold in the application), the system triggers an alarm instruction and an adjustment instruction.

[0058] The heat-sensitive probe is placed in the inner wall of the airway lumen of the tracheal intubation tube of the patient, and the heat-sensitive probe is used to collect original airway temperature data in the inner wall of the airway lumen at a second preset frequency; the original airway temperature data are subjected to the voltage signal conversion processing, the analog-digital conversion processing, the filtering processing and the outlier rejection processing to obtain target airway data.

[0059] The specific process for airway temperature monitoring (real-time detection of temperature by a thermistor or RTD (Resistance Temperature Detector) embedded in the airway) is as follows:

[0060] First, the thermistor deployment method: 1. The thermistor is placed on the inner wall of the airway lumen of the tracheal cannula, 1-3 cm away from the distal end of the airbag (to avoid interference from the throat and airbag), and directly contacts the respiratory airflow; 2. The probe is connected to the external module through a micro wire to avoid increasing the diameter of the cannula; 3. The probe has high thermal sensitivity (response time <1 second) and can accurately capture the temperature changes of the inhaled and exhaled air.

[0061] Further, after the airway original temperature data in the airway lumen inner wall is collected by the thermistor, the airway original temperature data is subjected to voltage signal conversion processing, analog-digital conversion processing, filtering processing, and outlier removal processing to obtain target airway data. The specific implementation process is as follows: 1. Obtain the resistance change corresponding to the airway original temperature data (generated by the thermistor), and convert the resistance change into a voltage signal (the thermistor converts the temperature change into a resistance change, which can be directly converted using the manufacturer's temperature-resistance relationship table, the resistance change is converted into a voltage change through a voltage dividing circuit, and the VREF reference voltage provided by the single-chip microcomputer is used as the reference voltage, wherein the capacitor in the circuit can filter the generated spike voltage, thus obtaining an analog voltage); 2. Input the analog voltage signal to an analog-digital converter to convert the voltage signal into a data signal (convert the analog voltage into an analog voltage through the single-chip microcomputer ADC); 3. Filter the digital signal after analog-digital conversion to process the noise in the data (the specific process of filtering is as follows: use a filter to analyze the voltage waveform of the analog voltage, find the second stable data segment, find the rule, obtain the ideal interval time of stable data, periodically read the next data segment according to this interval time, each data is filtered according to the first layer filtering algorithm, the second layer data delay processing is completed, and the data is also stored in the register for use as data for the third layer filtering); 4. Remove the outliers of the filtered data to remove the data that obviously do not meet the requirements, and finally obtain the target airway data. Through the above processing process of the airway original temperature data, it can be ensured that the airway original temperature data can be smoothly input into the electrocardiogram monitor, and at the same time, the accuracy of the image generated by the electrocardiogram monitor is also ensured.

[0062] In the present application, the micro pressure sensor for collecting the cuff pressure and the thermal probe for collecting the airway temperature are connected to the electrocardiograph monitor, the electrocardiograph monitor realizes real-time monitoring according to the collected target pressure data and target airway data, and adjusts the parameters of the cuff pressure and the airway temperature in the tracheal tube in time according to the needs, so as to ensure that the air pressure and the temperature of the tracheal tube of the patient are normal.

[0063] In step S20, a preset safe pressure interval is determined, if the target pressure data is not in the preset safe pressure interval, first alarm prompt processing and pressure adjustment processing are performed to obtain the cuff pressure alarm data and the pressure adjustment result. The preset safe pressure interval includes a first preset pressure threshold and a second preset pressure threshold, and the first preset pressure threshold is less than the second preset pressure threshold; the cuff pressure alarm data includes first cuff pressure alarm data and second cuff pressure alarm data; and the pressure adjustment result includes first pressure adjustment result and second pressure adjustment result.

[0064] The preset safe pressure interval is set in the present application, when it is detected that the cuff pressure in the tracheal tube of the patient exceeds the preset safe pressure interval, it is determined that the cuff pressure is abnormal, therefore, the cuff pressure is compared with the preset safe pressure interval to alarm and prompt the information of the excessively high or low cuff pressure, and the abnormal cuff pressure is also adjusted by the pre-set instrument to ensure that the cuff pressure of the patient is in the preset safe pressure interval, so that the life safety of the patient is effectively ensured.

[0065] Specifically, a preset safe pressure interval is determined, and the target pressure data is compared with the preset safe pressure interval; if the target pressure data is less than the first preset pressure threshold in the preset safe pressure interval, low pressure risk alarm prompt is performed to obtain the first cuff pressure alarm data, and the patient's tracheal tube is treated by a micro electric air pump or a micro peristaltic pump to obtain the first pressure adjustment result; if the target pressure data is greater than the second preset pressure threshold in the preset safe pressure interval, high pressure risk alarm prompt is performed to obtain the second cuff pressure alarm data, and the patient's tracheal tube is treated by a micro electromagnetic valve to obtain the second pressure adjustment result.

[0066] For the alarm mechanism, the alarm prompt logic of the present application is as follows: 1, set upper and lower threshold (i.e. the preset safety pressure range in the present application, including the first preset pressure threshold and the second preset pressure threshold): can be default 20-30 cmH2O, also can be manually adjusted; 2, over-limit judgment: if greater than 30 cmH2O (i.e. the second preset pressure threshold in the present application): alarm level I, prompt "high pressure risk" (i.e. the high pressure risk alarm prompt in the present application); if less than 20 cmH2O (i.e. the first preset pressure threshold in the present application): alarm level II, prompt "low pressure risk" (i.e. the low pressure risk alarm prompt in the present application); if not adjusted for a long time (such as fluctuating repeatedly within 15 seconds): alarm level III, prompt "adjustment failure" or "leakage risk".

[0067] The alarm form provided in the present application includes: 1, audible and visual double alarm, including high-frequency sound of buzzer (frequency changes with level) and flashing red or yellow prompt box of module body or monitor screen; 2, interface alarm, displaying "current pressure is abnormal! Please check the air bag or catheter" on the monitor interface; displaying abnormal duration and current pressure value.

[0068] When the tracheal intubation airbag pressure regulating device is started, self-checking is first performed, which includes indication (including "LED lamp" and "sound" two parts), air pump and air valve are all in self-checking state. The specific self-checking method includes: LED lamp green, yellow lamp flashes once, sound clicks, air pump, air valve switch once. After self-checking is completed, the system enters "standby" interface. Start function: press "start" key, start continuous monitoring function, the machine starts working according to the current set parameter value; if the real-time pressure data of the airbag monitored by the system within 15 seconds after the system is started is always lower than the preset threshold range (i.e. the preset safety pressure range in the present application), the system will not prompt, the air pump will continue to inflate, and after 15 seconds, if the real-time pressure data of the airbag is always lower than the lower limit of the preset threshold range, the buzzer and yellow LED light tube will issue sound and light prompts until the pressure value monitored by the system reaches the set value. But in normal use, if the pressure is abnormal, the system will start sound and light prompt within 5 seconds, when the CPU continuously monitors the real-time pressure data of the airbag through the pressure sensor for 5 seconds and the real-time pressure data is higher than the upper limit of the preset threshold range (i.e. the preset safety pressure range in the present application), the air release solenoid valve will automatically open, the system will release pressure, and the pressure will gradually decrease to the preset threshold range; when the CPU monitors the real-time pressure data of the airbag through the pressure sensor and the real-time pressure data is lower than the lower limit of the preset threshold range, the air pump will be started immediately to inflate so that the actual measured pressure tends to the preset threshold range, and when the CPU continuously monitors the real-time pressure data of the airbag through the pressure sensor for 5 seconds and the real-time pressure data is lower than the lower limit of the preset threshold range, the buzzer and yellow LED light tube will issue sound and light prompts. Through sound and light prompts, the staff can quickly know the abnormal state of the airbag pressure, and then adjust and handle it.

[0069] The present application also provides remote synchronization (if connected to a hospital system): 1. sending an alarm to the nurse station; 2. alarm records can be entered into the electronic medical record.

[0070] Further, in addition to the alarm prompt, the present application also provides a process for adjusting the pressure of the air bag, including: comparing the real-time pressure data of the air bag with the upper and lower limits of the preset threshold range, respectively; if the real-time pressure data of the air bag is between the upper and lower limits of the preset threshold range, it is determined that the real-time pressure data of the air bag is normal; if the real-time pressure data of the air bag is greater than the upper limit of the preset threshold range, it is determined that the real-time pressure of the air bag is too large, and the air is discharged by opening the air valve of the micro electromagnetic valve; if the real-time pressure data of the air bag is less than the lower limit of the preset threshold range, it is determined that the real-time pressure of the air bag is too small, and the air is inflated by opening the micro electric air pump or the micro peristaltic pump.

[0071] When the real-time pressure data of the air bag is normal, a gas pump closing control signal and a gas valve closing control signal are generated, wherein the gas pump closing control signal can control the micro electric air pump or the micro peristaltic pump for inflating the air bag to close, and the gas valve closing control signal can control the air valve of the micro electromagnetic valve for air discharge of the air bag to close; when the real-time pressure of the air bag is too large and needs to be discharged, a gas pump closing control signal and a gas valve opening control signal are generated, wherein the gas pump closing control signal can control the micro electric air pump or the micro peristaltic pump for inflating the air bag to close, and the gas valve opening control signal can control the air valve of the micro electromagnetic valve for air discharge of the air bag to open; when the real-time pressure of the air bag is too small and needs to be inflated, a gas pump opening control signal and a gas valve closing control signal are generated, wherein the gas pump opening control signal can control the gas pump for inflating the air bag to open, and the gas valve closing control signal can control the air valve of the micro electromagnetic valve for air discharge of the air bag to close. Turn on the power switch, press the "start" key, and start the continuous monitoring function. The real-time acquisition of the pressure sensor data is used to monitor the gas filling degree in the air bag, and is displayed on the display screen; when the acquisition data is between the upper and lower limits of the preset threshold range, the gas pump is closed and the gas valve is closed; when the data exceeds the upper limit value, the gas pump is closed and the gas valve gap is opened; when the data is lower than the lower limit value, the gas pump is opened and the gas valve is closed.

[0072] For the maintenance process of the air bag pressure, the present application provides an active pressure regulating mechanism: 1. automatic inflation: if the pressure is lower than the set value, the system activates the micro electric air pump or the micro peristaltic pump to slowly inject air into the air bag; 2. automatic air discharge: if the pressure is too high, the system releases the gas by controlling the micro electromagnetic valve to open, thereby reducing the pressure.

[0073] The specific adjustment process realizes closed-loop control, including: real-time pressure feedback, control instruction correction, action implementation, re-detection, and steady-state maintenance.

[0074] It can be understood that, for the inflation process when the air bag pressure is too low, the micro electric air pump or the micro peristaltic pump is arranged in the application, the micro electric air pump or the micro peristaltic pump is electrically connected with the electrical control module, the air inlet of the micro electric air pump or the micro peristaltic pump is connected with the outside for conveying gas, and the micro pressure sensor is electrically connected with the micro electric air pump or the micro peristaltic pump. The application also provides an inflation connector, and the inflation pipeline is connected with the inflation connector, and the inflation connector adopts a clamping sleeve connector or a luer connector.

[0075] The control method for the air bag pressure of the tracheal cannula provided by the application can realize accurate control of the air bag pressure of the tracheal cannula, so that the pressure is within the preset threshold range (i.e., the preset safe pressure interval in the application), and overcomes the defects of low real-time detection degree and manual detection in the prior art, ensures the accuracy and reliability of the air bag pressure, and further protects the life safety of the patient.

[0076] Further, the influence of the air bag on the trachea of the patient needs to be considered during the process of increasing or reducing the pressure of the air bag in the tracheal cannula, therefore, the application also provides an inflation monitoring module to realize the influence of the air bag on the trachea of the patient during the inflation process of the air bag. The specific implementation process is as follows: the inflation monitoring module is used to monitor the air bag pressure in real time, a preset inflation pressure threshold can be set, when the threshold is exceeded, an alarm is given and the inflation is stopped to avoid the air bag compressing the trachea of the patient.

[0077] Generally, the inner diameter of the trachea of a male is larger than that of a female, the inner diameter of the trachea of an adult is larger than that of a child, and the inner diameter of the trachea of a person with a larger body shape is also larger, therefore, the preset inflation pressure threshold can be set according to the gender, age and body shape of the patient.

[0078] It can be understood that the present invention provides a universal endotracheal cannula, which includes a cannula assembly and an inflation monitoring assembly; by controlling the pressure of the airbag filled in the cannula assembly to control the inner diameter of the cannula body in the cannula assembly, the function of adjusting the inner diameter of the cannula is realized, thereby improving the versatility of the endotracheal cannula; and the inflation monitoring assembly sets a preset inflation pressure threshold based on the air pressure of the airbag in the cannula assembly, thereby preventing the airbag from expanding and compressing the patient's trachea; at the same time, under the monitoring action of the inflation monitoring assembly, the airbag fixes the cannula body in the cannula assembly to the patient's trachea with appropriate air pressure, thereby improving the fixation efficiency of the endotracheal cannula.

[0079] Step S30: Determine a preset safe temperature range. If the target airway data is not within the preset safe temperature range, perform a second alarm prompt process to obtain airway temperature alarm data. The preset safe temperature range includes a first preset temperature threshold and a second preset temperature threshold, and the first preset temperature threshold is less than the second preset temperature threshold.

[0080] Similar to the above-mentioned detection of airbag pressure, for the detection of airway temperature, a preset safety temperature range is set in the present invention, and the target airway data in the patient's tracheal intubation is compared with the preset safety temperature range to identify whether the airway temperature in the patient's tracheal intubation is abnormal. When an abnormality occurs, an alarm will be issued to prompt the staff to identify the patient's status and handle the abnormality, which can further ensure the patient's life safety and receive timely rescue.

[0081] Specifically, a preset safety temperature range is determined, and the target airway data is compared with the preset safety temperature range; if the target airway data is less than the first preset temperature threshold in the preset safety temperature range, or the target airway data is greater than the second preset temperature threshold in the preset safety temperature range, an alarm prompt is performed to obtain airway temperature alarm data.

[0082] The airway data acquisition and conversion process includes: 1. The temperature signal is converted into a voltage signal by the resistance change generated by the thermistor probe; 2. The voltage signal is sent to the module's built-in ADC (Analog-to-Digital Converter), with a sampling frequency typically set to 1 Hz (adjustable) to achieve second-level temperature acquisition; 3. The data is collected once every second, and the system automatically records and caches the timestamp + temperature value as a data pair.

[0083] Furthermore, when the airway temperature in the patient's endotracheal tube is too high, in order to restore the airway temperature to normal, the present invention uses low-temperature gas, which is sprayed into a mist and blown into the patient's endotracheal tube. This can effectively weaken the uneven specific heat in the endotracheal tube, thereby taking away a large amount of heat to reduce the internal temperature of the endotracheal tube.

[0084] Step S40: Generate airbag pressure display data based on the target pressure data, the pressure adjustment result, and the airbag pressure alarm data; generate airway temperature display data based on the target airway data and the airway temperature alarm data; and visualize the airbag pressure display data and the airway temperature display data on the electrocardiogram monitor.

[0085] After obtaining the target pressure data and target airway data in the patient's tracheal intubation, the present invention will send the target pressure data and target airway data as well as related adjustment data and alarm data to the electrocardiogram monitor. After receiving these data, the electrocardiogram monitor will generate corresponding display diagrams and trend diagrams, which can enable staff to intuitively obtain the status information of the patient's tracheal intubation, so as to timely understand and deal with the patient's abnormal status.

[0086] Specifically, the airbag pressure display data and the airway temperature display data are sent to the electrocardiogram monitor; an airbag pressure trend curve chart is generated by the electrocardiogram monitor based on the airbag pressure display data; an embedded chart library is called by the electrocardiogram monitor, and an airway temperature trend curve chart is generated by the embedded chart library based on the airway temperature display data; the airbag pressure display data, the airbag pressure trend curve chart, the airway temperature display data and the airway temperature trend curve chart are visually displayed on the electrocardiogram monitor.

[0087] For data processing and interface interaction: the data of each sampling will be cached and uploaded to the host system of the ECG monitor.

[0088] The host system of the ECG monitor will synchronously generate the following data: 1. Real-time numerical display; 2. Trend curve; 3. Fluctuation amplitude alarm record.

[0089] The ECG monitoring system interface is used to display data content. The airbag module data is displayed in the monitor interface as a separate module window or an integrated interface tab, as shown in Table 1:

[0090] Table 1: Display format of airbag module data on the monitor interface

[0091] Item Presentation form Current airbag pressure value Digital display (cm H20) <!-- 9 -->]]> Set target pressure interval 20-30 cm H2O (adjustable) Historical trend curve Line graph (past 5-30 minutes) Alarm information record Time stamp + alarm type Regulation state Current "inflation / deflation / stable" Regulation execution number Cumulative digital statistics Module connection state "On-line or disconnected" icon

[0092] The tracheal tube cuff pressure monitoring system provided by the embodiment of the application can display the real-time pressure data of the cuff and can send alarm information through the electrocardiograph, so that the medical staff can conveniently check the pressure operation state of the tracheal tube cuff pressure adjusting device through the electrocardiograph in real time when the electrocardiograph is used by the medical staff, thereby facilitating the medical staff to quickly respond and centrally manage.

[0093] The uploading and processing process of the airway temperature data includes: 1. After filtering and outlier rejection processing, the collected data is uploaded to the central processing system of the electrocardiograph through RS-485, USB or BLE; 2. All temperature points enter the real-time trend curve generation module and are stored in the patient's current monitoring record; 3. Synchronized with the ventilation period of the ventilator to realize the rhythmic observation of the inspiration temperature and the expiration temperature.

[0094] The generation process of the temperature trend curve is as follows:

[0095] 1. Data sampling and time calibration: the system samples the current temperature at a fixed frequency (for example, 1 Hz); each data point has a timestamp + temperature value, for example: T1: 36.8℃; T2: 36.7℃; T3: 36.6℃, etc.

[0096] 2. Trend line drawing mechanism: call the embedded chart library (such as LVGL, QtChart, etc.) in the electrocardiograph system; plot the temperature data of the past 5 minutes, 15 minutes, 30 minutes or a custom time period in time order on the X axis (time) and the Y axis (temperature); can realize: line chart or smooth curve; dynamic update (sliding window method); label temperature abnormal area (highlight above 38.5℃ and below 35.0℃); superimposed with the patient's body temperature curve to determine whether there is local airway temperature abnormality.

[0097] 3. Clinical significance prompt: threshold reminder can be set, and if temperature drops suddenly (such as below 34℃, which is the first preset temperature threshold in the application) or rises sharply for a short time (> 39℃, which is the second preset temperature threshold in the application), the interface will pop up a prompt; the temperature change trend can also be analyzed in conjunction with the breathing cycle curve to evaluate the ventilation state and heat dissipation efficiency.

[0098] The beneficial effects of the application are:

[0099] 1. Continuous, accurate and intelligent control of the tracheal tube cuff pressure is realized, and the frequency of manual detection is significantly reduced;

[0100] 2. Airway temperature and pressure data are integrated in the same monitoring interface, improving information integration efficiency;

[0101] 3. Reduce the work burden of medical staff, improve the quality of airway management, and prevent complications;

[0102] 4. Adapt to existing ECG monitoring system, no additional terminal, save cost.

[0103] Further, the present application is based on the above technical features of technical development, including: 1, can set different warning value, support intelligent algorithm learning different patients individualized airbag pressure curve; 2, data automatic recording and remote transmission function, can be used for subsequent medical quality analysis; 3, can access hospital information system (HIS, Hospital Information System) and carry out electronic medical record record linkage; 4, future can expand to CO monitoring, tidal volume monitoring and other respiratory management functions.

[0104] Among them, the intelligent learning algorithm mainly refers to that the system is based on the historical airbag pressure data, airway temperature change and other physiological parameters of patients, and individualized modeling and prediction are automatically carried out through the algorithm model, to realize more accurate airway management, and the specific implementation steps include: 1, patient airbag pressure response mode learning: automatically identify the airway feedback characteristics (such as pressure drift speed, leakage trend) of different patients to the same set pressure; 2, clinical habit data learning: record the pressure interval commonly set by different medical staffs for specific patient groups, to assist subsequent setting recommendation; 3, fluctuation frequency and trend identification: through continuous monitoring, learn the fluctuation trend of patient airway with body position, cough, sedation state; 4, temperature parameter correlation learning: correlate airway temperature change and pressure stability, to evaluate whether there is infection risk or airway dryness sign.

[0105] The whole "intelligent learning" process is divided into five stages: 1. Data acquisition stage: continuously collect airbag pressure (sample every second), airway temperature and alarm events; synchronously collect patient vital signs (if integrated with electrocardiogram monitoring system, such as SpO2 and heart rate); all data are recorded with timestamp. 2. Feature extraction stage: extract from historical pressure curve: mean pressure; maximum and minimum value (P_max, P_min); fluctuation frequency; spike duration; regulation delay. 3. Modeling and classification stage: use machine learning models such as K-Means clustering, RNN (recurrent neural network), etc.; classify patients into patterns (such as "highly sensitive airway", "low stable type" and "rapid air leakage type", etc.); train the model to fit its optimal pressure change curve. 4. Parameter optimization stage: according to the model output, intelligently recommend: individualized target pressure range (for example, dynamically adjust from 20-30cmH2O to 22-28cmH2O); regulation frequency (set automatic inflation and deflation cycle); alarm sensitivity (reduce false alarm rate). 5. Continuous update stage: complete records are entered into the cloud or database after each ventilation or intubation process; continuously optimize model weights through batch training; realize long-term iterative upgrade.

[0106] The application can also be provided with linkage mode with HIS (hospital information system): the linkage with HIS system adopts standard medical interface protocol (such as HL7 (Health Level Seven, international standard protocol specially used for exchange of electronic data between different applications in medical and health field), FHIR (Fast Healthcare Interoperability Resources)), which can realize the following functions: 1. Electronic medical record synchronization: automatically push the monitored airbag pressure curve, alarm events, temperature trend chart to the patient's electronic medical record; HIS can display device number, parameter setting, operator record. 2. Doctor's order closed loop: when the HIS system issues "intubation pressure maintenance" doctor's order, the device will receive the set target pressure and duration; automatically return the completion status after execution, realizing closed loop. 3. Data return and quality control interface: data is returned in standard XML / JSON format; support for quality control platform later statistics, such as device running time, abnormal rate and alarm times, etc.
