Description

Technical Field

[0001] The present application relates to the field of artificial intelligence, and in particular to a method and system for intelligently adjusting the oxygen output concentration of an oxygen generator. Background Art

[0002] At present, most mainstream oxygen generators on the market use traditional pressure swing adsorption (PSA) oxygen production technology, using nitrogen molecular sieves to separate nitrogen and oxygen in the air to produce high-concentration oxygen. Although the technology of these oxygen generators is relatively mature, most of them still have some limitations, including the following issues:

[0003] 1. Existing oxygen concentrators usually have a simple built-in oxygen concentration detection device to monitor the concentration level of oxygen output. These devices mostly use zirconium oxide sensor technology, but the detection accuracy and response speed are relatively limited and are easily affected by environmental conditions (such as temperature and humidity changes). 2. Most existing oxygen concentrators provide fixed flow adjustment options, such as 1L / min, 3L / min, 5L / min, etc. Users need to manually select the appropriate flow gear, which relies on the user's manual setting and lacks the ability to intelligently adjust the flow according to actual needs. 3.

[0060] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0061] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0062] Specifically, Figure 1 As shown, the method may include:

[0063] Step S101, obtaining the real-time oxygen output concentration of the oxygen concentrator and the physiological parameter values ​​of the patient.

[0064] Optionally, the real-time oxygen output concentration of the oxygen concentrator refers to the oxygen output concentration currently set by the oxygen concentrator, and the patient's physiological parameter value refers to some medical indicator values ​​of the patient, such as blood oxygen saturation, heartbeat data, pulse data, etc. The specific types of medical indicators included in the physiological parameters can be configured according to actual needs, and the embodiments of the present application are not limited. For example, when the patient has heart disease, the physiological parameter values ​​may include blood oxygen saturation, pulse data, heartbeat data, etc., and when the patient has both heart disease and diabetes, the physiological parameter values ​​may include blood glucose values, etc. in addition to blood oxygen saturation, pulse data and heartbeat data.

[0065] In an optional embodiment of the present application, the oxygen concentrator includes an oxygen concentration sensor, and obtaining the real-time oxygen output concentration of the oxygen concentrator includes:

[0066] Based on the electrochemical detection method, the real-time oxygen concentration analog signal output by the oxygen concentration sensor is obtained;

[0067] Digitally process the real-time oxygen concentration analog signal to obtain the initial real-time oxygen output concentration;

[0068] The initial real-time oxygen output concentration is filtered according to the set filtering method to obtain the real-time oxygen output concentration of the oxygen concentrator.

[0069] Optionally, the oxygen concentrator in the present application includes a high-performance oxygen concentration sensor, and then the real-time oxygen concentration analog signal output by the oxygen concentration sensor can be obtained by an electrochemical detection method. At this time, the real-time oxygen concentration analog signal obtained based on the electrochemical detection method will have improved detection accuracy and response speed compared to the oxygen concentration analog signal obtained by the technology based on the zirconium oxide sensor in the prior art, and will not be easily affected by environmental conditions (such as temperature and humidity changes).

[0070] Furthermore, the real-time oxygen concentration analog signal can be digitally processed to obtain the initial real-time oxygen output concentration. Specifically, the real-time oxygen concentration analog signal output by the oxygen concentration sensor can be digitally processed using a high-speed data acquisition module. At this time, since the noise in the analog signal may be effectively suppressed during the digital processing, the corresponding filtering method can be set in advance in the embodiment of the present application, and then the initial real-time oxygen output concentration is filtered based on the set filtering method to obtain the real-time oxygen output concentration of the oxygen concentrator. The real-time oxygen output concentration obtained at this time will be more accurate and reliable. Optionally, the specific filtering method can be set based on the actual situation, and the present application does not limit this.

[0071] Step S102, inputting the real-time oxygen output concentration and the physiological parameter value into the oxygen concentration adjustment model to obtain the target oxygen output concentration currently matched with the patient.

[0072] Optionally, the present application may adopt machine learning to train an oxygen concentration regulation model, and then the obtained real-time oxygen output concentration and physiological parameter values ​​may be input into the oxygen concentration regulation model. The oxygen concentration regulation model will obtain a target oxygen output concentration that is more suitable for the patient based on the input real-time oxygen output concentration and the physiological parameter values ​​obtained by the patient.

[0073] In an optional embodiment of the present application, the oxygen concentration adjustment model is obtained by the following method:

[0074] Obtain a training sample set, the training sample set including sample pairs, each sample pair including sample data and a corresponding sample label, wherein the sample data includes a sample physiological parameter value and a sample oxygen output concentration value, and the sample label represents a labeling result of the oxygen output concentration corresponding to the sample pair;

[0075] The initial neural network model is trained based on each sample pair until the loss function corresponding to the initial neural network model converges, and the initial neural network model at the end of the training is used as the oxygen concentration adjustment model;

[0076] Among them, the input of the initial neural network model is the sample pair, and the output is the annotation result of the oxygen output concentration corresponding to the sample physiological parameter value in the sample pair. The value of the loss function represents the difference between the predicted result of the oxygen output concentration corresponding to each sample pair output by the model and the annotation result corresponding to each sample pair.

[0077] Optionally, the present application can obtain a training sample set, which includes sample pairs, each sample pair includes sample data and a corresponding sample label, and the sample data refers to the sample physiological parameter value and the sample oxygen output concentration value, and the corresponding sample label is the annotation result of the oxygen output concentration that matches the input sample data.

[0078] Furthermore, each sample pair can be input into the initial neural network model, and the initial neural network model can output the oxygen output concentration corresponding to each sample pair. Then, the value of the loss function corresponding to the model can be determined based on the output prediction results of each sample pair and the labeling results corresponding to each sample pair. If the determined loss function value does not converge, the network parameters of the initial neural network model can be adjusted, and then each sample pair can be input into the initial neural network model after adjusting the parameters again, and the value of the loss function can be determined again based on the output prediction results and the labeling results corresponding to the sample pairs. If it still does not converge, the network parameters of the initial neural network model are adjusted again until the corresponding loss function value converges. Among them, the value of the loss function corresponding to the model represents the difference between the prediction results corresponding to each sample pair output by the model and the labeling results corresponding to each sample pair. When the loss function converges, it indicates that the difference between the prediction results corresponding to each sample pair output by the model and the labeling results corresponding to each sample pair meets the requirements, that is, the prediction results of the sample pairs output by the model are close to the labeling results of the sample pairs.

[0079] In the present application, since the oxygen concentration adjustment model is trained based on a large amount of training sample data, the target oxygen output concentration obtained based on the oxygen concentration adjustment model is data obtained by referring to more cases, and the obtained target oxygen output concentration will also be more matched with the patient. In this process, medical staff no longer need to spend a lot of time querying patient data and then making an oxygen concentration output plan, which will be faster and more convenient.

[0080] In an optional embodiment of the application, the physiological parameter value includes the patient's real-time physiological parameter value and the patient's historical data; the real-time physiological parameter value includes real-time blood oxygen saturation and real-time pulse data; the historical data includes the patient's blood oxygen saturation, pulse data and oxygen output concentration used in a historical period;

[0081] After obtaining the target oxygen output concentration currently matched to the patient, the method further includes:

[0082] The real-time physiological parameter value and the target oxygen output concentration are encrypted and stored in a storage module of the oxygen concentrator according to a set data encryption method, wherein the storage module includes a ring buffer;

[0083] The real-time physiological parameter values ​​and the target oxygen output concentration are bound to the patient in the storage module as the patient's historical data.

[0084] Optionally, the acquired physiological parameter values ​​may include both the patient's real-time physiological parameter values ​​and the patient's historical data. The historical data may be the patient's blood oxygen saturation, pulse data and oxygen output concentration used in a previous period of time. Of course, if the patient suffers from multiple diseases, the historical data may also include parameter values ​​corresponding to each disease, such as the patient's blood sugar value in the past month, etc. Therefore, the embodiment of the present application does not limit the physiological parameter values ​​included in the historical data.

[0085] Correspondingly, after obtaining the target oxygen output concentration, the previously acquired real-time physiological parameter values ​​and target oxygen output concentration can also be encrypted according to the set data encryption method and stored in the storage module in the oxygen concentrator. In the storage module, the acquired real-time physiological parameter values ​​and target oxygen output concentration will also be bound to the patient as the patient's historical data, so that when the patient's target oxygen output concentration is determined later, the patient's historical physical condition can be better referred to to ensure that the determined target oxygen output concentration is more in line with the patient's physical condition.

[0086] Among them, the storage module is equipped with a storage chip that can save the user's oxygen concentration, blood oxygen saturation, heart rate and other data, and adopts a circular buffer design, so it can ensure that the device can still effectively record data after running for a long time, and will not lose key data due to exhaustion of storage space. It also uses encryption technology to encrypt and store data, further improving the security of data storage.

[0087] In an optional embodiment of the application, after obtaining the physiological parameter value of the patient, the method further includes:

[0088] Compare the acquired real-time physiological parameter values ​​with the preset parameter safety range;

[0089] If the real-time physiological parameter value exceeds the parameter safety range, a health alarm instruction is sent to the terminal device so that the device manager can make adjustments according to the health alarm instruction. The health alarm instruction includes the identification of the physiological parameter that exceeds the parameter safety range.

[0090] Optionally, in order for nursing staff or doctors to remotely monitor the patient's physiological data and equipment status. Once an abnormal situation (such as low oxygen concentration, abnormal blood oxygen level, etc.) is detected to ensure timely response, the parameter safety range corresponding to each physiological parameter can be pre-set in the embodiment of the present application, so that after obtaining the patient's real-time physiological parameter value, the obtained real-time physiological parameter value can be compared with the preset corresponding parameter safety range. If it exceeds the parameter safety range, a health alarm instruction is sent to the terminal device bound to the oxygen concentrator. The health alarm instruction includes the identification of the physiological parameter that exceeds the parameter safety range. After receiving the health alarm instruction, the equipment manager (such as medical staff) of the oxygen concentrator can promptly know that the patient's current physiological parameter is abnormal, so as to treat the patient in time. Among them, the specific display form of the health alarm instruction can be set according to actual needs, and the embodiment of the present application is not limited. For example, information can be sent to the terminal device, or the terminal device can set a ring tone alarm when receiving the health alarm instruction. For example, when the acquired blood oxygen value is lower than 90, the terminal device rings a set ring tone alarm.

[0091] In an optional embodiment of the present application, after obtaining the real-time oxygen output concentration of the oxygen concentrator and the physiological parameter value of the patient, the method further includes:

[0092] Receiving a data query instruction sent by a terminal device, the data query instruction including at least one of an oxygen concentrator operation status query instruction, a historical data query instruction, a real-time physiological parameter value query instruction, and an oxygen output concentration query instruction;

[0093] The target data information is obtained according to the query specification, and the target data information is encrypted according to a preset encryption method to obtain the encrypted target data information; the encrypted target data information is sent to the terminal device so that the equipment management personnel can monitor the health status of the oxygen concentrator and the patient in real time through the terminal device.

[0094] Optionally, in order for nursing staff or doctors to remotely monitor the patient's physiological data to ensure timely response, a data query instruction may be sent to the oxygen concentrator through the terminal device, and the data query instruction includes at least one of an oxygen concentrator operation status query instruction, a historical data query instruction, a real-time physiological parameter value query instruction, and an oxygen output concentration query instruction. Further, after receiving the data query instruction, the oxygen concentrator may obtain the corresponding target data information according to the query specification, encrypt it according to a preset encryption method, and then send the encrypted target data information to the terminal device.

[0095] Step S103, adjusting the oxygen output concentration of the oxygen concentrator according to the target oxygen output concentration, so that the oxygen output concentration of the oxygen concentrator is the target oxygen output concentration.

[0096] Step S104, sending the target oxygen output concentration to a terminal device bound to the oxygen concentrator, so that the equipment manager can monitor the real-time oxygen output concentration of the oxygen concentrator in real time through the terminal device.

[0097] Optionally, after determining the target oxygen output concentration, the oxygen output concentration of the oxygen concentrator can be set as the target oxygen output concentration, and after the setting is completed, the target oxygen output concentration can be sent to a terminal device bound to the oxygen concentrator. At this time, the equipment manager can monitor the real-time oxygen output concentration of the oxygen concentrator in real time through the terminal device.

[0098] In an optional embodiment of the present application, the oxygen output concentration of the oxygen concentrator is adjusted according to the target oxygen output concentration so that the oxygen output concentration of the oxygen concentrator is the target oxygen output concentration, including:

[0099] The molecular sieve and the compressor of the oxygen concentrator are adjusted by a PID (Proportiona, Integral and Derivative) control algorithm so that the oxygen output concentration of the oxygen concentrator is the target oxygen output concentration.

[0100] Optionally, when the oxygen output concentration of the oxygen concentrator is set to the target oxygen output concentration, the molecular sieve of the oxygen concentrator and the compressor of the oxygen concentrator can be adjusted by a PID control algorithm so that the oxygen output concentration of the oxygen concentrator is the target oxygen output concentration.

[0101] In an optional embodiment of the present application, the oxygen concentrator includes a PI (Proportiona and Integral) controller, and the molecular sieve of the oxygen concentrator and the compressor of the oxygen concentrator are adjusted by a PID control algorithm, including:

[0102] Obtaining set discretization parameters, and discretizing the PI controller according to the discretization parameters to obtain a discretized PI controller;

[0103] Based on the discretized PI controller, the switching frequency of the molecular sieve of the oxygen concentrator is adjusted through the PID control algorithm, and based on the discretized PI controller, the operating speed of the compressor of the oxygen concentrator is adjusted through the PID control algorithm.

[0104] Optionally, in order to ensure that the error of the set target oxygen output concentration is as small as possible, the PI controller included in the oxygen concentrator can be adjusted based on pre-set discretization parameters to obtain a discretized PI controller, and then based on the discretized PI controller, the switching frequency of the molecular sieve of the oxygen concentrator and the operating speed of the compressor of the oxygen concentrator are adjusted through a PID control algorithm.

[0105] Among them, the PID algorithm is used to implement the PI controller to generate two independent control outputs u1 and u2: u1 is used to adjust the switching frequency of the solenoid valve (i.e., molecular sieve) to control the adsorption / desorption time of the molecular sieve; u2 is used to adjust the operating speed of the compressor to control the oxygen pressure.

[0106] The output u(t) of the PI controller consists of two parts: proportional (P) and integral (I). The application formula is as follows:

[0107] u(t)=K P ×e(t)+K i ×∫00 t e(τ)dτ

[0108] Where u(t) is the output of the controller, e(t) = r(t) - y(t) is the error at the current moment, r(t) is the set reference value, y(t) is the current measurement value, and K P is the proportional gain, K i is the integral gain.

[0109] Optionally, the PI controller is discretized, which can be specifically as follows:

[0110] Assuming the discretization time step Δt is 10ms, the error change at each moment is e[k], then the application formula can be written as:

[0111] Where u[k] is the control output at the kth moment, e[k] is the error at the kth moment, Σ k i=0 e[i]×Δt is the cumulative integral of the error, the integration time step is Δt (10ms), and Kp and Ki are the proportional and integral gains of the controller.

[0112] Optionally, in order to prevent integral saturation and cause the controller output to lose control, the threshold of the integral term is limited and the maximum value of the integral term I is set. max and minimum value I min ,at this time:

[0113] I[k]=min(max(I[k-1]+e[k]×Δt,I min ),I max )

[0114] Where e[k] is the error at the kth moment, I[k] is the control output at the kth moment, Δt is the integration time step, and I max is the maximum value of the integral term and I min is the minimum value of the integral term.

[0115] Furthermore, in order to avoid the PI controller from over-responding to small errors, the dead zone range can be set to [-0.5, 0.5]. When the error e[k] is less than this value, the error is considered to be 0.

[0116]

[0117] The formula of the discretized PI controller is:

[0118] u[k]= K p ×e[k]+ K I × I [k]

[0119] Wherein, e[k]=r[k]-y[k]], r[k] is the set reference value, and y[k] is the current measured value.

[0120] Based on the above formulas, the final formula of the decentralized PI controller is:

[0121] u[k]=K P ×(r[k]-y[k])+K I ×min(max(I[k-1]+(r[k]-y[k])×Δt,I min ),I max )

[0122] Where u[k] is the control output at the kth moment, r[k] is the set reference value, y[k] is the current measured value, and I max is the maximum value of the integral term and I min is the minimum value of the integral term, Kp and Ki are the proportional and integral gains of the controller, and Δt is the integration time step.

[0123] Accordingly, based on u1, the switching frequency of the solenoid valve (i.e., the molecular sieve) is adjusted to control the adsorption / desorption time of the molecular sieve, specifically including setting the cycle T valve Adjust with the output u1 of the PI controller, that is:

[0124] T valve = clamp(T default +K T ×u1,T min ,T max )
