Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
With the continued development of medical technology, ventilator devices play a vital role in assisting the breathing of patients. In the current field of breathing machine equipment, the method for determining the pressure at the tail end of a pipeline is mainly divided into two types, firstly, the method directly adopts the pressure of the inner cavity of the breathing machine equipment body as the tail end pressure, and the condition of the gas pressure value at the tail end of the pipeline can be reflected by monitoring the change of the gas pressure value of the inner cavity of the breathing machine equipment, so that the method is relatively direct and simple, and additional complex configuration is not needed. However, the limitation is that the elasticity of the tubing material may affect the accuracy of the end pressure data that is ultimately obtained, i.e., the tubing material itself has a certain elasticity, which results in the end gas pressure value of the tubing being smaller than the gas pressure value in the internal chamber of the ventilator device, and this elasticity effect may be due to the material properties of the tubing, such as rubber or elastic plastic, which may deform when the gas flows. Thus, the line end pressure data obtained in this manner may not be accurate enough, and in some applications where end pressure accuracy is required, this may cause problems.
Another way is to introduce a three-way line connecting it to the end of the line and to the ventilator device body to obtain the gas pressure value at the end of the ventilator device line, by which configuration the pressure at the end of the line can be measured more directly, bypassing the elastic influence of the line material. However, this approach is relatively cumbersome to operate, requires additional plumbing connections, and increases the complexity of the system, as two separate lines need to be effectively managed and controlled, which can reduce the ease of use and efficiency of operation of the device for some healthcare personnel or patients.
Moreover, the conventional method cannot fully consider the influence of the temperature and the humidity of the pipeline gas of the breathing machine equipment on the terminal pressure value of the pipeline, and the gas temperature and the humidity have important influence on the terminal pressure value output by the breathing machine, but the conventional method often ignores the factors, so that the influence on the actual experience and the treatment effect of a patient is estimated to be insufficient.
For special cases such as infants or chronic respiratory disease patients, their need for end pressure values may be more sensitive and errors in traditional methods may have a greater impact on their treatment.
In general, conventional methods have limitations in measuring the end pressure value of the ventilator circuit, which may affect the therapeutic effectiveness and comfort of the patient. Thus, improving accuracy, taking into account more influencing factors, reducing interference with the patient, and achieving more accurate end pressure value measurements are currently a problem to be solved.
In view of this, the embodiment of the application provides a method, a device, an apparatus and a storage medium for determining an end pressure value of an end of a ventilation pipeline of a ventilator, in which, in determining an end pressure value of an end of a ventilation pipeline of a ventilator, not only a gas pressure value corresponding to a device chamber is considered, but also a gas temperature value and a gas humidity value related to the end pressure value of the ventilation pipeline are obtained.
The method for determining the end pressure of the ventilation pipeline can be used for computer equipment, wherein the computer equipment can be a server, and the server can be a single server or a server cluster consisting of a plurality of servers.
In one embodiment, as shown in fig. 1, there is provided a vent line end pressure determination method, which is described as being used for a computer device, the method including the steps of:
step 101, acquiring a gas pressure value corresponding to an equipment chamber of the breathing machine equipment, and acquiring a gas temperature value and a gas humidity value of a ventilation pipeline in the breathing machine equipment.
The equipment chamber of the ventilator equipment is a specific space or chamber inside the ventilator equipment, usually referred to as a closed area or vessel inside the ventilator equipment, which is the area for storing gas or regulating the flow of gas, providing support for the normal operation of the ventilator and for gas delivery. During ventilator operation, the equipment chamber is typically interconnected with other critical components (e.g., air circuits, valves, sensors, etc.) to ensure proper air flow regulation and control.
In the embodiment of the application, the real-time gas pressure value in the equipment cavity is measured and acquired through the pressure sensor arranged or connected in the equipment cavity of the breathing machine equipment, and the gas pressure value is transmitted to the control system of the computer equipment.
Optionally, in a data processing unit in the computer device, the voltage or current signal output by the pressure sensor may be parsed and converted into an actual gas pressure value, that is, the received analog signal of the pressure sensor is converted into a digital signal by an analog-to-digital converter or the like, and the obtained digital signal is subjected to filtering and calibration processing to eliminate possible noise or errors.
Then, through corresponding temperature sensors and humidity sensors arranged in or near the ventilator equipment, the gas temperature value and the gas humidity value of the ventilation pipeline in the ventilator equipment are measured and acquired, and are transmitted to a control system of the computer equipment, and the acquired gas temperature and humidity value is subjected to certain pretreatment in the computer equipment, so that the operations of filtering the gas temperature and humidity value to remove noise and the like can be included.
In this way, the computer device can acquire the gas pressure value corresponding to the device chamber of the breathing machine device, and the gas temperature value and the gas humidity value of the ventilation pipeline in the breathing machine device through the mode.
And 102, acquiring an end pressure compensation value according to the gas temperature value and the gas humidity value.
As described above, the computer device obtains the gas temperature value and the gas humidity value of the ventilation line in the ventilator device, and obtains the end pressure compensation value of the ventilation line in the ventilator device based on the gas temperature value and the gas humidity value.
Hereinafter, a process in which the computer device obtains the tip pressure compensation value based on the gas temperature value and the gas humidity value will be exemplarily described.
In one possible embodiment, the obtained gas temperature value and gas humidity value may be input into a corresponding calculation module in the computer device, which calculates the compensation value of the end pressure by using the values of the gas temperature and the humidity according to a predetermined algorithm and a pressure compensation formula, wherein the pressure compensation formula may consider factors such as the thermal expansion and contraction characteristics of the gas and the influence of the humidity on the gas density.
In another possible embodiment, the computer device may employ a machine learning algorithm to obtain the tip pressure compensation value based on the gas temperature value and the gas humidity value, and first, a machine learning model is built from a plurality of training data including the gas temperature value, the gas humidity value, and the corresponding tip pressure compensation value. The model may be a regression model that, by learning complex relationships between input characteristics (gas temperature and gas humidity values) and output values (end pressure compensation values), in real-time operation, the computer device receives current gas temperature and humidity values and inputs these values into a trained machine learning model, which through the learned relationships, predicts the corresponding end pressure compensation values.
Thus, with any of the above embodiments, the computer device may obtain the tip pressure compensation value based on the gas temperature value and the gas humidity value.
And 103, compensating the gas pressure value by using the end pressure compensation value to obtain the end pressure value of the tail end of the ventilation pipeline.
In this embodiment of the present application, the computer device applies the obtained end pressure compensation value to the gas pressure value, that is, performs operations such as adding, multiplying, and the like, on the end pressure compensation value and the measured raw gas pressure value, and performs compensation processing on the gas pressure value according to specific situations, where the result of this compensation is the end pressure value of the ventilation pipeline end.
The following illustrates the implementation of the ventilation circuit end pressure determination method of embodiments of the present application in connection with a ventilator apparatus.
An advanced ventilator device is provided for monitoring the respiratory environment state of a patient, a device chamber is arranged in the ventilator device and is connected with a pressure sensor, and the pressure sensor measures the gas pressure value of the device chamber in real time and transmits the value to a control system of a computer device. At the same time, a corresponding temperature sensor and humidity sensor are provided in or near the ventilator device, by means of which the gas temperature and humidity values of the ventilation line are measured and transmitted to the control system of the computer device. The computer device then calculates an end pressure compensation value based on the acquired gas temperature and humidity values, which may be implemented by a predetermined algorithm and a pressure compensation formula, which may be an equation based on a physical model or a model learned from a large amount of training data by machine learning, for example, using machine learning, in which the model learns a complex relationship between the gas temperature humidity value and the end pressure compensation value during training, taking into account the thermal expansion and contraction characteristics of the gas and the influence of humidity on the gas density. Finally, the computer device performs compensation processing on the gas pressure value measured in real time by using the obtained end pressure compensation value to obtain an end pressure value of the end of the ventilation pipeline, wherein the processing may include adding or multiplying the end pressure compensation value with the original gas pressure value, the specific operation depends on the adopted compensation algorithm, and the final result is the end pressure value of the end of the ventilation pipeline.
According to the method, the device, the equipment and the storage medium for determining the end pressure of the ventilation pipeline, the end pressure compensation value is obtained according to the gas temperature value and the gas humidity value, and the end pressure compensation value is used for carrying out compensation processing on the gas pressure value to obtain the end pressure value of the tail end of the ventilation pipeline. Like this, compare in the mode that directly adopts the pressure value of breathing machine equipment inside cavity as ventilation line terminal pressure value among the conventional art, the embodiment of the application is in the terminal pressure value's of the ventilation line terminal of breathing machine equipment in the process of confirming the ventilation line terminal pressure value of ventilation line, the influence of gas temperature and gas humidity in the ventilation line to the terminal pressure value of ventilation line is considered, utilize the terminal pressure compensation value that is confirmed according to ventilation line's gas temperature value and gas humidity value to carry out the compensation processing to the gas pressure value that equipment cavity corresponds, can revise the error that causes by gas temperature and gas humidity, finally obtain the terminal pressure value of ventilation line terminal after the correction, make the calculation value of pipeline terminal pressure more be close with actual pipeline terminal pressure value, consequently, the embodiment of the application has improved the accuracy of confirming ventilation line terminal pressure value.
In one embodiment, referring to fig. 2, based on the embodiment shown in fig. 1, the present embodiment refers to a process in which the computer device obtains an end pressure compensation value according to a gas temperature value and a gas humidity value in step 102, and the process includes step 201 shown in fig. 2:
in step 201, a mathematical operation is performed on the gas temperature value and the gas humidity value to obtain an end pressure compensation value.
As an alternative embodiment, the process of obtaining the end pressure compensation value by performing mathematical operations on the gas temperature value and the gas humidity value by the computer device includes: multiplying the gas temperature value by a first preset coefficient to obtain a first product, multiplying the gas humidity value by a second preset coefficient to obtain a second product, wherein the first preset coefficient and the second preset coefficient are both larger than zero, and the first preset coefficient is larger than the second preset coefficient; the first product and the second product are multiplied to obtain the end pressure compensation value.
Specifically, the computer equipment processes the gas temperature value and the gas humidity value, and firstly, multiplies the gas temperature value by a number of a first preset coefficient to obtain a first product; secondly, multiplying the gas humidity value by another number called a second preset coefficient to obtain a second product, wherein the first preset coefficient and the second preset coefficient are both values larger than zero, and the first preset coefficient is larger than the second preset coefficient, wherein the first preset coefficient is 1.443/0.75, and the second preset coefficient is 1/25; and finally, multiplying the first product and the second product to obtain the end pressure compensation value.
Wherein the first preset coefficient and the second preset coefficient are obtained by performing a plurality of experiments and observation, the experiments can comprise systematic measurement and analysis of the relation between the temperature and the humidity of the gas, or by experimentally setting different temperature and humidity conditions, measuring the change of the pressure compensation value of the observed end, and by collecting and analyzing the experimental data, the optimal first preset coefficient and the optimal second preset coefficient can be determined by using a statistical method, namely, the first preset coefficient and the second preset coefficient are obtained by performing a plurality of experiments, and the adjustment and the optimization are performed according to the actual observation result, so that the calculation and the control of the compensation value can be performed on the pressure value of the end gas.
Thus, through the above mode, the computer device performs mathematical operation on the gas temperature value and the gas humidity value to obtain the terminal pressure compensation value, and the terminal pressure compensation value considers the gas temperature and the gas humidity, so that the computer device can better adapt to different environmental conditions. Meanwhile, the first preset coefficient and the second preset coefficient are obtained through a large number of experiments and observations, so that the first preset coefficient and the second preset coefficient are adjusted and optimized, and the best performance in practical application can be ensured.
In one embodiment, referring to fig. 3, based on the embodiment shown in fig. 2, the present embodiment refers to a process in which the computer device performs compensation processing on the gas pressure value by using the end pressure compensation value in step 103 to obtain an end pressure value of the end of the ventilation pipeline, where the process includes step 301 shown in fig. 3:
in step 301, the end pressure compensation value and the gas pressure value are multiplied to obtain an end pressure value.
In this embodiment, the computer device has obtained a corresponding end pressure compensation value according to the gas temperature value and the gas humidity value, and compensates the real-time gas pressure value obtained by the pressure sensor in the chamber of the device through the end pressure compensation value, that is, multiplies the end pressure compensation value by the gas pressure value, multiplies the two values, and superimposes the end pressure compensation value obtained by previous calculation on the real-time gas pressure value to obtain a corrected end pressure value, as shown in formula (1), wherein,is the end pressure value; />Is the internal gas pressure value of the breathing machine; />Is the gas humidity; />Is the gas temperature.
(1)
Wherein, the formula (1) is obtained through a great number of experiments and experience researches, and by analyzing the experimental results, the optimal adjustment coefficient can be determined so as to ensure that the end pressure value obtained by calculation is equal to the actual end pressure value of the pipeline and can be stabilized in a certain range under various conditions.
Thus, by taking the influence of the gas temperature and the humidity into consideration and performing corresponding compensation in calculation, the computer equipment enables the calculated value of the pipeline end pressure to be equal to the actual pipeline end pressure value, which is an important advantage for the performance and the safety of the breathing machine equipment in practical application.
Based on the embodiment shown in fig. 1, referring to fig. 4, the method for determining the end pressure of the ventilation line in this embodiment may further include steps 401 and 402 shown in fig. 4:
step 401, detecting whether the end pressure value is within a standard pressure value range.
The gas pressure in the ventilator device is usually set within a range of standard pressure values, which is set based on factors such as specific requirements of the patient or medical conditions, so as to ensure that the patient can breathe comfortably and safely, and if the end pressure value exceeds the set standard range, discomfort may be caused to the patient or a certain safety risk may exist.
In the embodiment of the application, the computer equipment compares the obtained end pressure value of the ventilation pipeline of the breathing machine equipment with a preset standard pressure range, wherein the standard pressure range is preset according to medical requirements and safety parameters, and if the end pressure value is in the preset standard range, the current end pressure value is continuously maintained; if the end pressure value is beyond the standard range, corresponding measures are taken to adjust the end pressure value.
If the end pressure value is not within the standard pressure range, the gas pressure in the vent line is adjusted to make the end pressure value of the end of the vent line within the standard pressure range, step 402.
As described above, optionally, when it is detected that the end pressure value is not within the preset standard pressure value range, the computer device may initiate an automatic adjustment procedure so that the end pressure value of the ventilation circuit of the ventilator device is within the standard pressure value range, and it is understood that the computer device may analyze the deviation of the obtained end pressure value from the standard range and determine the deviation value (increase or decrease pressure value) to be adjusted; the computer device then sends an adjustment signal to the pressure regulator or related mechanism in the ventilation circuit, during which the gas pressure in the ventilation circuit is correspondingly adjusted so that the end pressure value of the ventilation circuit of the ventilator device gradually approaches within a preset standard pressure value range, wherein the entire adjustment process may be dynamic, and the computer device continuously evaluates the condition and environmental changes of the ventilator device and makes corresponding adjustments to maintain the end pressure value within the standard pressure range. For example, in a ventilator device having a predetermined standard pressure range of 10 to 15 cm of water (cmH 2O) and a detected end pressure value of 8 cmH2O, the computer device analyzes the deviation, i.e., the difference between the detected end pressure value and the lower end of the standard pressure range, and finds the difference to be 2 cmH2O, and then the computer device determines the deviation value to be adjusted, sends an adjustment signal to the pressure regulator in the ventilation line indicating an increase in the end pressure value so that the end pressure value gradually approaches the lower end of the standard range, and during the adjustment phase the pressure regulator or associated machinery will increase the gas pressure in the ventilation line accordingly, such as by adjusting it to 10 cmH2O, the computer device may also continuously monitor the end pressure value and make additional adjustments as needed to bring the end pressure value within the standard pressure range.
In another possible implementation, the professional will periodically check the end pressure value of the ventilator device based on the computer device to ensure that the end pressure value meets the preset standard pressure range, and once it is detected that the end pressure value deviates from the standard pressure range, the professional will perform real-time analysis to determine the deviation of the end pressure value from the standard pressure range, and determine whether to increase or decrease the pressure value by the deviation value to be adjusted; then, the professional performs corresponding operation, and uses a control interface or a regulator on the breathing machine equipment to adjust a pressure regulator or a related mechanical device in the ventilation pipeline so that the end pressure value of the ventilation pipeline gradually approaches to a preset standard pressure value range; during the adjustment phase, the practitioner periodically monitors the end pressure value and makes additional adjustments as needed to ensure that the ventilator device is able to maintain a stable end pressure value within standard limits.
Thus, through any of the above embodiments, the computer device may detect whether the end pressure value is within the standard pressure value range, and if the end pressure value is not within the standard pressure value range, adjust the gas pressure in the ventilation pipeline, so that the end pressure value of the end of the ventilation pipeline is within the standard pressure range, and ensure that the patient is in a safe and comfortable state when receiving treatment.
Based on the embodiment shown in fig. 4 and referring to fig. 5, before the computer device adjusts the pressure of the gas in the ventilation line, the method for determining the end pressure of the ventilation line in this embodiment may further include step 501 and step 502 shown in fig. 5:
step 501, outputting end pressure abnormality prompt information, where the end pressure abnormality prompt information is used to instruct to adjust the gas pressure in the ventilation pipeline.
Wherein the end pressure refers to the gas pressure at the end of the venting line, which refers to the tubing used to convey the gas, and the end is the final part of this line, i.e. the location to which the gas is conveyed; the abnormality notification is a message indicating an abnormality, or warning, where the abnormality notification is related to the tip pressure, i.e., indicates that there is an abnormality or problem in the tip pressure value.
In this embodiment, in the ventilation pipeline of the ventilator device, the gas pressure at the end of the pipeline is monitored or measured in real time, once an abnormality in the end pressure value is detected, a next operation is performed, and an abnormality prompt message is output, where the abnormality prompt message explicitly indicates that an abnormality exists in the end pressure, and the abnormality prompt message may be presented in a form that is easy to understand, such as an alarm, a text message, or other visual notification modes.
Step 502, adjusting the gas pressure in the vent line, comprising: and if a gas pressure adjustment instruction aiming at the terminal pressure abnormality prompt information is received, adjusting the gas pressure in the ventilation pipeline.
As described above, when the indication of the abnormality in the end pressure value is triggered, the computer device initiates a corresponding automated reaction mechanism involving the ability to receive a gas pressure adjustment command, and if the ventilator device receives a gas pressure adjustment command for the abnormality in the end pressure, the ventilator device adjusts the gas pressure value in the ventilation line according to the parameters and requirements in the gas pressure adjustment command, which may include changing the opening of the valve, adjusting the speed of the pump, or performing other corresponding control operations to bring the end gas pressure value within the standard pressure range.
Therefore, by means of the mode, the computer equipment adjusts the gas pressure value in the ventilation pipeline according to the output end pressure abnormality prompt information, so that the computer equipment can timely and effectively cope with the abnormal condition of the end pressure value of the ventilation pipeline of the breathing machine equipment, and the gas pressure value in the ventilation pipeline is maintained in a safe and stable range, so that the normal operation of the breathing machine equipment is ensured.
In one embodiment, a vent line end pressure determination method is provided for a computer device, see FIG. 6, the method comprising the steps of:
step 601, acquiring a gas pressure value corresponding to an equipment chamber of the ventilator equipment, and acquiring a gas temperature value and a gas humidity value of a ventilation pipeline in the ventilator equipment.
Step 602, multiplying the gas temperature value by a first preset coefficient to obtain a first product.
Step 603, multiplying the gas humidity value by a second preset coefficient to obtain a second product, where the first preset coefficient and the second preset coefficient are both greater than zero, and the first preset coefficient is greater than the second preset coefficient.
Step 604, multiplying the first product and the second product to obtain an end pressure compensation value, and multiplying the end pressure compensation value and the gas pressure value to obtain an end pressure value.
Step 605, it is detected whether the end pressure value is within the standard pressure value range, if the end pressure value is not within the standard pressure value range, that is, the end pressure abnormality indication information is output, and the end pressure abnormality indication information is used for indicating to adjust the gas pressure in the ventilation pipeline.
In step 606, the gas pressure in the vent line is adjusted so that the end pressure value at the end of the vent line is within the standard pressure range.
Hereinafter, the implementation of the vent line end pressure determination method of the above embodiment will be exemplarily described.
As shown in fig. 7, it is assumed that there is a ventilator device, where the monitored gas pressure in the device chamber is P, the gas temperature in the ventilation pipeline is T, and the gas humidity is H, and in the operation process, the ventilator device firstly acquires the gas pressure value P, the gas temperature value T, and the gas humidity value H in real time, where the acquisition modes specifically include: the real-time gas pressure value in the equipment cavity can be measured and obtained through a pressure sensor arranged or connected in the equipment cavity of the breathing machine equipment, and the gas pressure value is transmitted to a control system of the computer equipment; and measuring and acquiring a gas temperature value and a gas humidity value of a ventilation pipeline in the breathing machine equipment through corresponding temperature sensors and humidity sensors arranged in or near the breathing machine equipment, and transmitting the gas temperature value and the gas humidity value to a control system of the computer equipment, wherein the acquisition of a gas pressure value P, a gas temperature value T and a gas humidity value H can be completed through corresponding information acquisition modules. Then, the gas temperature value T is multiplied by a first preset coefficient to obtain a first product, the gas humidity value H is multiplied by a second preset coefficient to obtain a second product, the first product and the second product are multiplied to obtain a terminal pressure compensation value, and the terminal pressure compensation value is multiplied by the gas pressure value P to obtain a terminal pressure value. And finally, detecting whether the end pressure value is in the standard pressure value range, and if the end pressure value is not in the standard pressure value range, outputting an end pressure abnormality prompt message to prompt that the gas pressure in the ventilation pipeline needs to be regulated so as to enable the end pressure value to be in the standard pressure range.
