[0002] As a key emergency rescue technology, cardiopulmonary resuscitation (ECPR) is widely used in the rescue process of emergency situations such as sudden cardiac arrest. Timely and effective CPR operations are crucial to saving patients' lives. In order to improve the emergency response capabilities of rescue personnel, cardiopulmonary resuscitation (ECPR) training has become an important part of various emergency training programs. However, traditional CPR training often relies on manual evaluation of trainees' operation quality, which has problems such as inconsistent evaluation standards, strong subjectivity, and untimely feedback, resulting in slow improvement of trainees' operation level and difficulty in quantifying the training effect.

[0003] Existing CPR training equipment mainly conducts operation exercises through simulated human models, and trainees perform compression training based on the feedback of the models. However, the evaluation methods of these devices are usually relatively simple, relying only on the response of the simulated model, and cannot comprehensively and accurately evaluate the quality of trainees' operation, especially in the comprehensive evaluation of multi-dimensional factors such as compression depth, frequency, and strength.

[0021] Secondly, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the schematic diagrams are only examples and should not limit the scope of protection of the present invention.

[0022] Please see attached Figure 1 As shown, a control system for emergency ECPR rescue training operation is provided, including: It includes a pressing receiving module, a time period building module, a pressing evaluation module, an interval compensation module, an efficiency quality module, a force compensation module and a pressing scoring module, wherein: A pressing receiving module is used to obtain the pressing resistance sensing sheet information of the cardiopulmonary resuscitation model, obtain the corresponding pressing force according to the pressing resistance sensing sheet information, and obtain the corresponding pressing depth according to the pressing force; A time period construction module is used to construct a verification time period, obtain compression depth information within the verification time period, determine whether the compression depth information meets the first preset condition, and if so, determine it as a valid cardiopulmonary resuscitation training operation, and construct an evaluation time period; An evaluation compression module is used to obtain the sensor sheet resistance compression data of the cardiopulmonary resuscitation model during the evaluation period; An interval compensation module is used to obtain the pressing interval data within the evaluation period and obtain the interval compensation coefficient according to the pressing interval data; The efficiency quality module is used to obtain the number of compressions data within the evaluation period, and obtain the number of compressions compensation coefficient according to the number of compressions data, and obtain the compression efficiency quality information according to the interval compensation coefficient and the number of compressions compensation coefficient; A force compensation module is used to obtain the pressing force data within the evaluation period and obtain the force compensation coefficient according to the pressing force data; The pressing scoring module is used to obtain the pressing quality score based on the pressing data of the sensor sheet resistance, the pressing efficiency quality value and the force compensation coefficient, and generate a training operation report.

[0023] In the above, the pressing receiving module obtains the pressing force and pressing depth data through the pressing resistance sensing sheet of the cardiopulmonary resuscitation model. The time period construction module verifies whether the pressing meets the first preset condition (such as whether the number of pressings meets the specification) according to the pressing depth data. If the condition is met, the current operation is determined to be a valid cardiopulmonary resuscitation training operation and enters the evaluation period. The evaluation pressing module records the change data of the resistance of the sensing sheet during the pressing operation during the evaluation period. The interval compensation module obtains the pressing interval data during the evaluation period and calculates the interval compensation coefficient according to the pressing interval data. The efficiency quality module counts the number of pressings during the evaluation period and calculates the pressing efficiency quality value in combination with the pressing interval compensation coefficient. The force compensation module evaluates the pressing force data and calculates the force compensation coefficient. The pressing scoring module comprehensively considers the pressing data of the sensing sheet resistance, the pressing efficiency quality value, and the force. It can collect key data (such as compression depth, interval, strength, etc.) during the compression process in real time, and dynamically adjust the evaluation period according to preset conditions to ensure the validity and accuracy of the data. It comprehensively evaluates the quality of cardiopulmonary resuscitation compression operations through multi-dimensional data such as compression depth, interval, number of times and strength, and provides comprehensive feedback. The introduction of interval compensation coefficient and strength compensation coefficient can correct the scoring deviation caused by uneven operation or strength deviation, and improve the scientific nature of the evaluation. Through the operation report generated by the compression scoring module, trainees and trainers can clearly understand the advantages and disadvantages of the compression process, which is convenient for targeted improvements. It automatically completes data collection, analysis and scoring, greatly reduces manual intervention, and improves training efficiency.

[0024] In a preferred embodiment, the pressure receiving module includes a pressure resistance information unit, an information extraction unit, a force calculation unit, a depth matching table unit, a target force unit and a depth acquisition unit, wherein: A compression resistance information unit, used to obtain compression resistance sensor information of a cardiopulmonary resuscitation model; An information extraction unit, used for obtaining the resistance change, initial resistance, sensitivity coefficient, elastic modulus and pressing force area of ​​the corresponding resistance sensing sheet according to the information of pressing the resistance sensing sheet; A force calculation unit, used to obtain the pressing force according to the resistance change, initial resistance, sensitivity coefficient, elastic modulus and pressing force area of ​​the resistance sensing sheet; A depth matching table unit, used to obtain a force depth table, wherein the force depth table includes a plurality of pressing interval forces and a pressing depth corresponding to each pressing interval force; A target force unit, used to obtain a target pressing interval force according to the pressing force; The depth acquisition unit is used to acquire the corresponding pressing depth from the force depth table according to the target pressing interval force.

[0025] In the above, the compression resistance information unit obtains the resistance information of the compression resistance sensing sheet through the compression resistance sensing sheet of the cardiopulmonary resuscitation model, and the information extraction unit extracts the following key parameters according to the original resistance information of the resistance sensing sheet: Resistance change: the difference in resistance before and after pressing; Initial resistance: the resistance value of the sensor in the state without external force; Sensitivity coefficient: the sensitivity of the sensor to external force; Elastic modulus: elastic properties of the sensor material; Pressing force area: the area in contact with the sensor during pressing; The force calculation unit calculates the pressing force according to the resistance change, initial resistance, sensitivity coefficient, elastic modulus and pressing force area of ​​the resistance sensing sheet. The calculation formula of the pressing force is: , where F represents the pressing force, E represents the elastic modulus, and R change Expressed as resistance change, R initial It is represented by the initial resistance, K is represented by the sensitivity coefficient, S is represented by the pressure-bearing area, and the depth matching table unit calls the built-in force depth table, which includes multiple pressure interval forces and their corresponding pressure depths. For example, the pressure interval 10N-20N corresponds to a pressure depth of 3cm, and the pressure interval 20N-30N corresponds to a pressure depth of 4cm. The target force unit matches the target pressure interval force in the force depth table according to the calculated pressure. The depth acquisition unit extracts the corresponding pressure depth from the force depth table according to the target pressure interval force. Through the combination of multiple parameters (such as resistance change, sensitivity coefficient, elastic modulus, etc.), the pressure can be accurately calculated to avoid calculation deviation caused by a single parameter error. With the help of the force depth table, the corresponding relationship between the pressure and the pressure depth can be quickly realized to ensure that the depth calculation meets the international standards for cardiopulmonary resuscitation, obtain the pressure data in real time, and dynamically calculate the pressure and depth to provide instant feedback for trainers.

[0026] In a preferred embodiment, the period construction module includes a verification period unit, a verification depth unit, a verification times unit, a threshold times unit, a times judgment unit and an evaluation period construction unit, wherein: A verification period unit, used to construct a verification period; A verification depth unit, used to obtain the pressing depth information during the verification period; A verification times unit, used to obtain the number of pressing times according to the pressing depth information and mark it as the verification times; A threshold number unit, used to obtain the number of pressing thresholds; A times determination unit, used to determine whether the number of verifications exceeds a threshold number of presses; If the verification times exceed the compression threshold times, it is determined as a valid CPR training operation and marked as the CPR implementation stage; The evaluation period construction unit is used to construct the evaluation period according to the verification period.

[0027] As mentioned above, the verification period unit divides the verification period into an idle time and a verification time. If the compression resistance sensing sheet of the cardiopulmonary resuscitation model does not detect a compression signal during the idle time, the system enters a waiting stage. When the compression resistance sensing sheet detects a compression signal, the system enters a verification period and starts to record compression depth information. The verification depth unit obtains compression depth information in real time during the verification period. The verification times unit counts the number of compressions based on the compression depth information during the verification period, which is called the verification times. For example, when the compression depth exceeds a preset threshold (such as 1 cm), it is counted as a valid compression. The threshold times unit obtains the compression threshold times (such as 3 cm) of the cardiopulmonary resuscitation training. 0 times), as the standard for judging whether to enter the stage of implementing cardiopulmonary resuscitation, the number judgment unit judges whether the verification number exceeds the threshold number of compressions. If it exceeds the threshold, the current operation is determined to be an effective cardiopulmonary resuscitation training operation, and the stage of implementing cardiopulmonary resuscitation is entered, that is, the trainees are undergoing effective cardiopulmonary resuscitation action training. The evaluation period construction unit constructs an evaluation period according to the operation situation of the verification period. By dividing the idle time and the verification time, it can dynamically adapt to the operation rhythm in the compression process, avoid the interference of invalid data, and improve data collection efficiency. The verification number is based on the compression depth information statistics to ensure the accuracy of the compression number and avoid data deviation caused by misoperation or invalid compression.

[0028] In a preferred embodiment, the evaluation period construction unit includes a start time unit, an average depth unit, an evaluation duration unit, a target depth unit, an evaluation duration acquisition unit, an end time unit and a period determination unit, wherein: A start time unit is used to obtain the time node when the compression depth information appears for the first time during the verification period and mark it as the start time of the evaluation period; An average depth unit, used to obtain a corresponding average pressing depth according to the pressing depth information; An evaluation duration unit, used to obtain a depth duration table, wherein the depth duration table includes a plurality of average compression depth intervals and an evaluation duration corresponding to each average compression depth interval; A target depth unit, used to obtain a target average compression depth interval according to the average compression depth; An evaluation duration acquisition unit, used to acquire a corresponding evaluation duration from a depth duration table according to a target compression average depth interval; An end time unit, used to obtain the end time of the evaluation period according to the evaluation duration and the start time of the evaluation period; The time period determination unit is used to obtain the evaluation time period according to the start time and end time of the evaluation time period.

[0029] As described above, the start time unit detects the time node when the compression depth information appears for the first time within the verification period, and marks it as the start time of the evaluation period. The average depth unit calculates the average compression depth based on all the compression depth data within the verification period. The evaluation duration unit obtains a built-in depth duration table, which contains multiple average compression depth intervals and their corresponding evaluation durations. According to the calculated average compression depth, the corresponding evaluation duration is matched. For example, if the average compression depth is 5.5cm, the [5-6cm] interval in the depth duration table is matched, and the corresponding evaluation duration is 30 seconds. The end time unit calculates the end time of the evaluation period based on the evaluation duration and the start time. The period determination unit finally determines the evaluation period based on the start time and the end time, and can accurately locate the start and end time of the evaluation period to ensure the integrity and validity of the evaluation data. According to the average compression depth and evaluation duration of different students, a personalized evaluation report can be generated in the follow-up to help students optimize operations in a targeted manner. It can record and analyze the compression depth and time information in real time, quickly generate evaluation periods, and improve the timeliness of data processing.

[0030] In a preferred embodiment, the interval compensation module includes a pressing interval unit, an interval duration unit and an interval compensation unit, wherein: A pressing interval unit, used to obtain pressing interval data within an evaluation period; An interval duration unit, used to obtain corresponding multiple pressing interval durations according to the pressing interval data; The interval compensation unit is used to obtain the corresponding interval compensation coefficient according to the duration of multiple pressing intervals.

[0031] In the above, the pressing interval unit extracts the pressing interval data by analyzing the time interval between two consecutive pressings in the evaluation period. The interval duration unit groups all the pressing interval data in the evaluation period to obtain the duration value of each interval. For example, if the pressing time points in the evaluation period are [1.0 seconds, 1.6 seconds, 2.3 seconds], the pressing interval data is [0.6 seconds, 0.7 seconds]. The interval compensation unit calculates the interval compensation coefficient according to the pressing interval duration. The calculation formula of the interval compensation coefficient is: , where t represents the interval compensation coefficient, i represents the number of multiple compression intervals, i=1,2,3…n, P i It is expressed as the duration of the i-th pressing interval, which can accurately reflect the pressing rhythm during the operation, help students optimize rhythm control, effectively correct the scoring deviation caused by uneven rhythm, and improve the accuracy and fairness of the evaluation results.

[0032] In a preferred embodiment, the efficiency quality module includes a pressing times evaluation unit, a total times unit, a times compensation table unit, a target times unit, a times compensation unit and an efficiency quality acquisition unit, wherein: An evaluation unit for pressing times, used to obtain the pressing times data within an evaluation period; A total number unit, used to obtain the corresponding total number of pressing times according to the pressing number data; A times compensation table unit, used to obtain a times compensation table, wherein the times compensation table includes a plurality of pressing times intervals and a times compensation coefficient corresponding to each pressing times interval; A target number unit, used to obtain a corresponding target number of pressing intervals according to the total number of pressings; A times compensation unit, used to obtain a corresponding times compensation coefficient from a times compensation table according to a target pressing times interval; The efficiency quality acquisition unit is used to acquire the compression efficiency quality value according to the interval compensation coefficient and the number compensation coefficient, and mark it as compression efficiency quality information.

[0033] As mentioned above, the evaluation pressing times unit obtains the pressing times data within the evaluation period and counts the effective pressing times data. The total times unit directly obtains the total pressing times value based on the pressing times data within the evaluation period. The times compensation table unit obtains a built-in times compensation table, which defines different pressing times intervals and their corresponding compensation coefficients. For example, the pressing times interval (times) 20-25 corresponds to a compensation coefficient of 1.2. The target times unit matches the corresponding pressing times interval in the times compensation table based on the total pressing times. The times compensation unit extracts the corresponding compensation coefficient from the times compensation table based on the target pressing times interval. The efficiency quality acquisition unit Combining the interval compensation coefficient and the number compensation coefficient, the compression efficiency quality value is calculated. The calculation formula for the compression efficiency quality value is a=c / t, where a represents the compression efficiency quality value, c represents the number compensation coefficient, t represents the interval compensation coefficient, and it is marked as the compression efficiency quality information. The calculated compression efficiency quality value is stored as part of the evaluation result and used to generate a training operation report. By obtaining the number of presses data and the total number of presses, it can intuitively reflect the trainees' operating efficiency during the evaluation period, help trainees understand whether their own operating rhythm meets the standards, and dynamically adjust the evaluation standards according to different number of presses to ensure the fairness and flexibility of the evaluation.

[0035] As described above, the evaluation force unit records the pressing force data by real-time monitoring the pressing action during the evaluation period. For example, the pressing force data during the evaluation period may be a set of values, such as [30N, 32N, 28N, 35N]. The force value unit extracts the force value of each press according to the pressing force data to form a pressing force sequence. The force compensation unit calculates the force compensation coefficient according to the pressing force value sequence. The calculation formula of the force compensation coefficient is: , where d is the force compensation coefficient, g is the number of multiple pressing force values, g=1,2,3…m, L g Expressed as the g-th pressing force value, it can effectively reduce the evaluation deviation caused by improper individual force and ensure the fairness and scientificity of the evaluation.

[0036] In a preferred embodiment, the compression scoring module includes a depth extraction unit, a compression quality unit, a scoring table unit, a target interval unit and a quality score acquisition unit, wherein: A depth extraction unit, used for acquiring corresponding multiple pressing depth values ​​according to the pressing data of the sensor sheet resistance; A pressing quality unit, used to obtain a pressing quality value according to a plurality of pressing depth values, a pressing efficiency quality value and a force compensation coefficient; A scoring table unit, used to obtain a scoring table, wherein the scoring table includes a plurality of compression quality interval values ​​and a compression quality score corresponding to each compression quality interval value; A target interval unit, used for obtaining a target pressing quality interval value according to the pressing quality value; The quality score acquisition unit is used to obtain the corresponding compression quality score from the score table according to the target compression quality interval value and generate a training operation report.

[0037] As mentioned above, the depth extraction unit extracts the pressing depth value corresponding to each pressing according to the pressing data of the sensor sheet resistance to form a pressing depth sequence. The pressing quality unit combines multiple pressing depth values, pressing efficiency quality values ​​and force compensation coefficients to comprehensively calculate the pressing quality value. The calculation formula of the pressing quality value is: , where A represents the compression quality, j represents the number of multiple compression depth values, j=1,2,3…r, Z jIt is represented as the jth compression depth value, a is represented as the compression efficiency quality value, d is represented as the force compensation coefficient, the scoring table unit loads the preset scoring table, which defines multiple compression quality interval values ​​and their corresponding compression quality scores, the target interval unit determines the compression quality interval value to which it belongs according to the calculated compression quality value, the quality score acquisition unit extracts the corresponding compression quality score from the scoring table as the final compression score, and integrates the compression quality score with other indicators to generate a comprehensive training operation report, including the trainees' operation performance and improvement suggestions. Through multi-dimensional comprehensive calculation, the trainees' compression quality can be scientifically and accurately quantified, avoiding the subjectivity of traditional evaluation methods. Through a clear scoring and feedback mechanism, trainees can gradually improve their compression actions, meet the operational standards of cardiopulmonary resuscitation, and improve the actual rescue success rate.

[0039] As mentioned above, the teaching aid model body 1 is an integral physical device that simulates the shape and structure of the human chest for trainees to perform cardiopulmonary resuscitation (ECPR) training. It is the basis of the entire device and provides a physical surface for pressing. The pressing module 2 is arranged on the teaching aid model body 1, usually located in the key pressing area of ​​the chest. When the teaching aid model body 1 is pressed, the pressing module 2 deforms following the pressing action, causing the metal sheet to deform, resulting in a change in the resistance value of the resistive sensing sheet. The change in resistance reflects the strength and depth of the pressing. The resistive sensing sheet is connected to the control terminal through an electrical connection to transmit the pressing information in real time. The control terminal is located inside the teaching aid model body 1 and is electrically connected to the resistive sensing sheet. When the resistance of the resistive sensing sheet changes, the control terminal receives these change signals and calculates key parameters such as pressing strength and depth through a preset algorithm. The control terminal performs corresponding control system operations based on the transmitted resistance change signal and provides real-time feedback to trainees to help them adjust the operation method to ensure that the pressing meets the ECPR standard.
