Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent cardiopulmonary resuscitation system. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) is a commonly used emergency treatment for cardiac arrest, primarily involving chest compressions to restore spontaneous breathing and circulation. Traditional manual CPR suffers from issues such as inconsistent compression quality and cumbersome procedures. Furthermore, due to the manual nature of the operation, variations in the rescuer's experience and skill can easily lead to ineffective compressions. While some CPR machines have emerged on the market, most offer only compressions and cannot meet the needs for real-time monitoring and intelligent adjustment of the patient's physiological state during treatment.

[0003] Existing cardiopulmonary resuscitation (CPR) machines primarily use electrically or pneumatically controlled reciprocating telescopic mechanisms to perform rhythmic, reciprocating chest compressions. While these mechanisms can fulfill the compression requirements, they have several shortcomings: Firstly, they lack intelligent monitoring systems, failing to automatically adjust compression depth and frequency based on individual patient differences, easily leading to uneven compression intensity or insufficient rebound, thus affecting resuscitation effectiveness. Secondly, existing equipment lacks a linkage mechanism with other emergency medical equipment, hindering coordinated operation during emergency treatment and impacting overall treatment outcomes. Furthermore, existing systems are deficient in the accuracy of their identification and judgment modules, making it difficult to promptly acquire compression execution status and patient physiological response parameters, affecting subsequent intelligent adjustment functions.

[0004] Currently, there is a lack of an effective method to solve the problems in existing technologies.

Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent cardiopulmonary resuscitation system to overcome the above-mentioned deficiencies.

[0007] To address the aforementioned technical problems, this invention provides an intelligent cardiopulmonary resuscitation (CPR) machine system, comprising: a real-time quality feedback module for acquiring compression quality parameters during CPR and generating compression quality feedback information characterizing the current chest compression execution state; a compression effect feedback module for acquiring the patient's vital sign parameters and generating compression effect feedback information characterizing the patient's physiological response state during the current chest compression; a control module for determining a deviation information parameter of the current resuscitation state relative to the preset compression parameters based on the compression quality feedback information, the compression effect feedback information, and preset compression parameters, and generating resuscitation control commands based on the deviation information parameter; and a resuscitation execution module for acquiring the air supply safety status. The system operates in a state where, when the gas supply safety condition meets preset safety conditions, the control module adjusts the chest compressions according to the resuscitation control commands and coordinates the breathing assistance commands with the chest compressions. The resuscitation control commands include compression adjustment commands and breathing coordination commands. When the gas supply safety condition does not meet the preset safety conditions, the control module restricts or stops the chest compressions and outputs an alarm message through the resuscitation execution module. When the control module receives a confirmation signal of spontaneous breathing recovery, or when the chest compression effect feedback information meets preset recovery conditions, the control module controls the resuscitation execution module to stop the chest compressions and puts the intelligent cardiopulmonary resuscitation machine system into a dormant or standby state.

[0008] Optionally, the real-time quality feedback module includes: a press detection unit for acquiring press depth-related parameters and / or press force-related parameters; a frequency detection unit for acquiring press frequency parameters; a time detection unit for acquiring at least one of press time parameters, pause time parameters, and total running time parameters; and a status detection unit for acquiring at least one of press start status parameters, pause status parameters, and running status parameters.

[0009] Optionally, the compression effect feedback module includes: an end-tidal carbon dioxide detection unit for acquiring the patient's end-tidal carbon dioxide parameters; a blood oxygen saturation detection unit for acquiring the patient's blood oxygen saturation parameters; a cardiac output detection unit for acquiring the patient's cardiac output parameters; and a vital signs analysis unit for generating the compression effect feedback information based on at least one of the end-tidal carbon dioxide parameters, blood oxygen saturation parameters, and cardiac output parameters.

[0010] Optionally, the control module is used to compare the pressure quality feedback information with the preset pressure parameters to determine the pressure execution deviation information parameters, and to compare the pressure effect feedback information with the preset response conditions to determine the physiological response deviation information parameters.

[0011] Optionally, the control module is used to correlate the compression quality feedback information and the compression effect feedback information obtained within the same resuscitation control cycle, and determine the resuscitation control command corresponding to the current resuscitation state based on the correlation processing result.

[0012] Optionally, the control module is configured to store or recall a set of preset compression parameters corresponding to the patient's body shape information; the control module is also used to determine the initial compression parameters based on the patient's body shape information, and to correct the initial compression parameters based on the deviation information parameters.

[0013] Optionally, the resuscitation execution module includes: an automatic compression unit for adjusting chest compression actions according to the compression adjustment command; and an automatic breathing unit for performing respiratory assistance actions under preset coordination conditions according to the breathing coordination command, so that the respiratory assistance actions are coordinated with the chest compression actions.

[0014] Optionally, the resuscitation execution module further includes: a gas source monitoring and alarm unit, used to acquire gas source quality parameters and process the gas source; and a wireless communication unit, used to send at least one of compression quality parameters, patient vital sign parameters, and gas source quality parameters to a remote terminal, and to receive parameter adjustment instructions sent by the remote terminal.

[0015] Optionally, the gas source monitoring and alarm unit includes a filter, a pressure sensor, a first overpressure protector, and a second overpressure protector. The pressure sensor is used to acquire gas source pressure parameters, and the first and second overpressure protectors are used to perform graded overpressure protection when the gas source pressure parameters meet preset overpressure conditions.

[0016] Optionally, the control module is configured to determine whether the gas source safety status meets the preset safety conditions before executing the parameter adjustment command; the control module is also used to update the deviation information parameters based on the reacquired compression quality feedback information and compression effect feedback information after the resuscitation execution module executes the resuscitation control command, and generate the resuscitation control command for the next resuscitation control cycle based on the updated deviation information parameters.

[0017] Beneficial effects:

[0018] The system obtains the execution status of chest compressions through a real-time quality feedback module and the compression effect feedback module obtains the patient's vital sign responses during the current resuscitation process. The control module correlates the compression quality feedback information, compression effect feedback information, and preset compression parameters. When the air supply safety status obtained by the resuscitation execution module meets the preset safety conditions, it generates and issues resuscitation control commands, ensuring that chest compressions and respiratory assistance actions are executed in coordination according to the control commands. This enables full monitoring of the cardiopulmonary resuscitation process, improving the controllability and traceability of compression quality; avoiding uneven compression force or insufficient rebound caused by manual operation, which is beneficial to improving the effectiveness of cardiopulmonary resuscitation; and recording and storing various parameters in real time for subsequent diagnosis and treatment.

It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0028] As mentioned earlier, existing cardiopulmonary resuscitation (CPR) machines primarily use electrically or pneumatically controlled reciprocating telescopic mechanisms to perform rhythmic reciprocating compressions. While these mechanisms can fulfill the compression requirements, they have several shortcomings: Firstly, the precision and effectiveness of the compression actuators are insufficient, making it difficult to guarantee accurate compressions. Furthermore, their large size makes installation inconvenient, especially unsuitable for rescues in confined spaces. Secondly, the lack of an intelligent monitoring system prevents the automatic adjustment of compression depth and frequency based on individual patient differences, easily leading to uneven compression intensity or insufficient rebound, thus affecting resuscitation effectiveness. In addition, existing equipment lacks a linkage mechanism with other emergency medical equipment, hindering coordinated operation during rescue operations and impacting overall treatment outcomes. Moreover, the accuracy of existing systems in their identification and judgment modules is insufficient, making it difficult to accurately obtain the CPR machine's model and parameters, affecting subsequent intelligent adjustment functions.

[0029] To address this issue, the present invention provides an intelligent cardiopulmonary resuscitation (CPR) system. This system uses a real-time quality feedback module to acquire the execution status of chest compressions, and a compression effectiveness feedback module to acquire the patient's vital signs during the current resuscitation process. A control module correlates the compression quality feedback information, compression effectiveness feedback information, and preset compression parameters. When the air supply safety status acquired by the resuscitation execution module meets preset safety conditions, a resuscitation control command is generated and issued, causing chest compressions and respiratory assistance actions to be executed in coordination according to the control command. This system enables full monitoring of the CPR process, improving the controllability and traceability of compression quality; avoids uneven compression pressure or insufficient rebound caused by manual operation, thus improving the effectiveness of CPR; and records and stores various parameters in real time, facilitating subsequent diagnosis and treatment.

[0030] The following is combined Figures 1-6 This invention is described in detail.

[0031] Example 1:

[0032] like Figure 1 As shown in the figure, an intelligent cardiopulmonary resuscitation (CPR) system provided in this embodiment of the invention includes a real-time quality feedback module, a compression effect feedback module, a control module, and a resuscitation execution module. The real-time quality feedback module and the compression effect feedback module are communicatively connected to the control module, and the resuscitation execution module is controllably connected to the control module. The real-time quality feedback module and the compression effect feedback module transmit data to the control module via a signal acquisition interface or a communication interface. The control module outputs electronic control commands to the resuscitation execution module via a drive interface, causing the automatic compression unit and the automatic breathing unit to perform corresponding actions. A gas source monitoring and alarm unit in the resuscitation execution module is located between the gas source and the automatic compression unit, ensuring that the gas source status is detected and judged before the chest compression action. In this connection relationship, the control module outputs electronic control commands, the gas source monitoring and alarm unit filters, monitors, and protects against overpressure in the gas source before it enters the automatic compression unit, and the automatic compression unit then performs chest compression actions according to the compression adjustment commands output by the control module, thus forming a coordinated relationship between the electronic control commands and the gas source-driven execution.

[0033] The real-time quality feedback module acquires compression quality parameters during cardiopulmonary resuscitation (CPR) and generates compression quality feedback information characterizing the current chest compression execution status. Specifically, compression quality parameters may include compression depth-related parameters and / or compression force-related parameters, compression frequency parameters, compression time parameters, pause time parameters, total execution time parameters, and compression status parameters. These parameters are collected by the compression detection unit, frequency detection unit, time detection unit, and status detection unit, respectively, and then sent to the control module. Upon receiving these parameters, the control module organizes them into feedback information reflecting the current chest compression execution status, used to determine whether the current compression action deviates from the preset compression parameters.

[0034] For example, after chest compressions are initiated, the compression detection unit continuously acquires parameters related to compression depth or compression force as the mechanical compression device acts on the patient's chest. The frequency detection unit simultaneously acquires the number of compressions per unit time, the time detection unit records the compression duration, pause time, and total running time, and the status detection unit records whether the mechanical compression device is in the activated, paused, or running state. This data is sent to the control module within the same resuscitation control cycle, and the control module uses this data to generate compression quality feedback information for the current cycle.

[0035] The chest compression effect feedback module acquires the patient's vital signs parameters and generates chest compression effect feedback information characterizing the patient's physiological response during the current chest compressions. The vital signs parameters may include end-tidal carbon dioxide (UTC) parameters, blood oxygen saturation parameters, and cardiac output parameters. UTC parameters reflect ventilation and perfusion-related status, blood oxygen saturation parameters reflect the patient's blood oxygenation status, and cardiac output parameters reflect changes related to perfusion. After receiving at least one of the above vital signs parameters, the vital signs analysis unit first determines whether the corresponding vital signs parameter is in a valid acquisition state. If the parameter is valid, it compares it with preset response conditions to form an interval judgment result, trend judgment result, or validity marker characterizing the current physiological response state. If the parameter is invalid, the corresponding detection branch is marked as invalid, and the judgment results corresponding to the valid detection branch are compiled into chest compression effect feedback information, which is then sent to the control module.

[0036] For example, during resuscitation, the end-tidal carbon dioxide detection unit acquires end-tidal carbon dioxide parameters, the blood oxygen saturation detection unit acquires blood oxygen saturation parameters, and the cardiac output detection unit acquires cardiac output parameters. The vital signs analysis unit does not directly change its actions based on a single instantaneous value. Instead, it organizes the vital signs parameters obtained within a resuscitation control cycle into compression effectiveness feedback information, which is then transmitted to the control module for correlation processing with the compression quality feedback information.

[0037] The control module determines the deviation parameters of the current resuscitation state relative to the preset compression parameters based on compression quality feedback, compression effect feedback, and preset compression parameters, and generates resuscitation control commands based on these deviation parameters. These resuscitation control commands include compression adjustment commands and respiratory coordination commands. The control module can also store or recall a set of preset compression parameters corresponding to the patient's body type information, and determine the initial compression parameters based on this information. The set of preset compression parameters can be formed based on equipment calibration results, operating procedures, manufacturer data, historical statistical results, or rules preset by medical personnel, and is used to provide at least one of the following: initial compression depth control, compression frequency control, and compression time control. Patient body type information can include at least one of height, weight, and age group, which can be entered by medical personnel before equipment startup or recalled by the system based on preset information.

[0038] Specifically, after receiving chest compression quality feedback, the control module compares it with preset chest compression parameters to determine chest compression execution deviation parameters; after receiving chest compression effect feedback, it compares it with preset response conditions to determine physiological response deviation parameters. Subsequently, the control module correlates the chest compression execution deviation parameters and physiological response deviation parameters within the same resuscitation control cycle to determine the resuscitation control command corresponding to the current resuscitation state.

[0039] For example, when the chest compression quality feedback indicates a deviation between the current compression action and preset compression parameters, and the compression effect feedback does not meet the preset recovery conditions, the control module generates a compression adjustment command to correct the chest compression action based on the deviation information parameters. Simultaneously, it generates a breathing coordination command to coordinate the breathing assistance actions with the chest compression actions. When the control module receives a confirmation signal of spontaneous breathing recovery, or when the compression effect feedback meets the preset recovery conditions, the control module stops generating control commands to increase chest compressions. Instead, it controls the resuscitation execution module to stop chest compressions and puts the system into a dormant or standby state.

[0040] The resuscitation execution module is used to acquire the gas supply safety status and, when the gas supply safety status meets preset safety conditions, adjusts the chest compression actions according to resuscitation control commands, and coordinates the respiratory assistance actions with the chest compression actions. The resuscitation execution module may include an automatic compression unit, an automatic breathing unit, a gas supply monitoring and alarm unit, and a wireless communication unit. The automatic compression unit adjusts the chest compression actions according to compression adjustment commands; the automatic breathing unit performs respiratory assistance actions under preset coordination conditions according to respiratory coordination commands; the gas supply monitoring and alarm unit acquires and processes gas supply quality parameters; and the wireless communication unit sends at least one of the following to a remote terminal: compression quality parameters, patient vital signs parameters, and gas supply quality parameters, and receives parameter adjustment commands from the remote terminal.

[0041] The air supply monitoring and alarm unit may include a filter, a pressure sensor, a first overpressure protector, and a second overpressure protector. The filter filters the air supply before it enters the automatic chest compression unit. The pressure sensor acquires the air supply pressure parameters. The first and second overpressure protectors provide tiered overpressure protection when the air supply pressure parameters meet preset overpressure conditions. Before executing parameter adjustment commands, the control module first determines whether the air supply safety status meets preset safety conditions. When the air supply safety status does not meet the preset safety conditions, the control module restricts or stops chest compressions and outputs an alarm message through the resuscitation execution module.

[0042] For example, when the air source pressure parameter is within the preset safety conditions, the control module allows the chest compression adjustment command to be sent to the automatic chest compression unit, causing the automatic chest compression unit to adjust the chest compression action. When the air source pressure parameter obtained by the pressure sensor reaches the preset overpressure condition corresponding to the first overpressure protector, the air source monitoring and alarm unit first executes the first-level protection and outputs an alarm message. When the air source pressure parameter further reaches the preset overpressure condition corresponding to the second overpressure protector, the control module restricts or stops the execution of the chest compression adjustment command, causing the system to enter a conservative processing state. If the remote terminal sends a parameter adjustment command at this time, the control module still first judges the air source safety status, and only performs the corresponding adjustment if the preset safety conditions are met.

[0043] Based on the aforementioned modules and their synergistic relationships, this invention generates mechanical execution feedback for chest compressions through a real-time quality feedback module, and physiological response feedback for the patient through a compression effect feedback module. A control module correlates and processes the mechanical execution feedback, physiological response feedback, and preset compression parameters. Finally, the resuscitation execution module performs compression adjustments and coordinated breathing actions when the gas supply safety condition is met. Therefore, the system can update deviation information parameters based on feedback results within the resuscitation control cycle and generate resuscitation control commands for the next resuscitation control cycle, which helps improve the coordination between chest compressions, respiratory assistance actions, and gas supply safety management.

[0044] Example 2:

[0045] To provide a more detailed explanation of the technical solutions provided in the above embodiments, the present invention also provides another preferred embodiment. In another embodiment of the present invention, the intelligent cardiopulmonary resuscitation machine system can sequentially complete the following steps according to the resuscitation process: compression quality acquisition, physiological response acquisition, deviation information determination, air source safety verification, resuscitation execution control, feedback update, and dormancy processing.

[0046] The real-time quality feedback module may include a pressure detection unit, a frequency detection unit, a time detection unit, and a status detection unit. The pressure detection unit acquires pressure depth-related parameters and / or pressure-related parameters; the frequency detection unit acquires pressure frequency parameters; the time detection unit acquires at least one of pressure time parameters, pause time parameters, and total running time parameters; and the status detection unit acquires at least one of pressure start status parameters, pause status parameters, and running status parameters.

[0047] The compression detection unit can acquire displacement-related information, force-related information, or calibrated compression depth-related information during chest compressions, based on the structure of the mechanical compression device. When the compression detection unit uses a force-measuring element, its detection results are used to characterize compression force-related parameters; when it uses a displacement-measuring element, its detection results are used to characterize compression depth-related parameters. When the control module needs to obtain compression depth-related parameters, it can organize force-related information, displacement-related information, or a combination of both into corresponding compression quality feedback information based on the equipment calibration relationship. In the compression force-related detection configuration, the compression detection unit can use a force-measuring element to acquire compression force-related parameters. The measurement range of the force-measuring element can be 0~50kg, and the resolution can be 0.1kg (the compression detection unit can distinguish every 0.1kg change in compression force or load). In another configuration, the measurement range of the force-measuring element can be 0~60kg, and the resolution can be 0.05kg; in yet another configuration, the measurement range of the force-measuring element can be 0~70kg, and the resolution can be 0.01kg. The pressing depth parameters are determined by displacement detection results or equipment calibration conversion results.

[0048] For example, if the compression detection unit continuously acquires several compression force-related parameters within a single recovery control cycle, the control module can use these parameters to determine whether the current compression action involves excessive or insufficient compression force, or abnormal rebound. If the compression detection unit is also equipped with a displacement detection component, the control module can combine the compression force-related parameters and compression depth-related parameters into compression quality feedback information. This processed feedback information is then input into the control module and compared with preset compression parameters.

[0049] In the frequency detection unit, the number of chest compressions per unit time is acquired, and a compression frequency parameter is generated. The frequency detection unit can be implemented using a high-frequency sensor or a detection element capable of detecting the reciprocating motion of the mechanical compression device; the detection result is used to generate the compression frequency parameter. In one configuration, the compression frequency sensor has a measurement range of 10–150 compressions / minute and a resolution of 0.1 compressions / minute (the frequency detection unit can distinguish a change of 0.1 compressions / minute per minute); in another configuration, the measurement range is 20–180 compressions / minute and the resolution is 0.05 compressions / minute; in yet another configuration, the measurement range is 30–200 compressions / minute and the resolution is 0.01 compressions / minute. These values ​​are for illustrative purposes only; the detection configuration of the frequency detection unit can be set according to the equipment calibration results.

[0050] For example, when the current pressing frequency obtained by the frequency detection unit is lower than the corresponding frequency range in the preset pressing parameter set, the control module can include this deviation in the pressing execution deviation information parameter, and generate a pressing adjustment command to increase the pressing frequency or adjust the pressing speed when the air source safety condition is met; when the current pressing frequency is within the preset range, the control module can maintain the current frequency-related control quantity, and continue to combine the pressing effect feedback information to determine whether fine adjustment is needed.

[0051] The time detection unit acquires compression time, pause time, and total running time parameters. It can be implemented using a time relay, a timing circuit, or an internal timing unit within the control module to record these parameters. In one configuration, the compression and pause time can be detected within a range of 1–999 seconds with a resolution of 0.1 seconds (the time detection unit can distinguish changes of 0.1 seconds). The total running time can be detected within a range of 1–999 minutes with a resolution of 0.1 minutes. In other configurations, the time parameter resolution can be 0.05 seconds or 0.01 seconds. These time parameters are sent from the time detection unit to the control module to record the recovery process and assist in determining the pause and running states.

[0052] For example, when the system pauses chest compressions or waits for the air supply to be restored, the pause time parameter is sent to the control module. If the pause time exceeds the time condition corresponding to the preset abnormal condition, the control module can output an alarm message through the resuscitation execution module and send the alarm message to a remote terminal via the wireless communication unit.

[0053] In the status detection unit, the system can acquire press-to-start status parameters, pause status parameters, and running status parameters. In a specific implementation, the press status sensor can use a microswitch to detect the press status, including start, pause, and other states. After obtaining the status parameters, the status detection unit transmits them to the control module, enabling the control module to confirm whether the control command has been actually responded to by the revival execution module.

[0054] For example, when the control module has output a press adjustment command, but the status detection unit reports that the mechanical pressing device is still in a paused state, the control module can determine that the current control command has not formed a valid execution feedback, and output an execution abnormality alarm message through the recovery execution module. This alarm message can be output locally or sent to a remote terminal via the wireless communication unit.

[0055] The chest compression effect feedback module may include an end-tidal carbon dioxide detection unit, a blood oxygen saturation detection unit, a cardiac output detection unit, and a vital signs analysis unit. The end-tidal carbon dioxide detection unit acquires the patient's end-tidal carbon dioxide parameters, the blood oxygen saturation detection unit acquires the patient's blood oxygen saturation parameters, the cardiac output detection unit acquires the patient's cardiac output parameters, and the vital signs analysis unit generates chest compression effect feedback information based on at least one of the aforementioned parameters.

[0056] The end-tidal carbon dioxide detection unit can acquire end-tidal carbon dioxide parameters using non-dispersive infrared detection. In one configuration, the end-tidal carbon dioxide detection range is 0–100 mmHg with a resolution of 0.1 mmHg; in another configuration, the detection range is 0–120 mmHg with a resolution of 0.05 mmHg; and in yet another configuration, the detection range is 0–150 mmHg with a resolution of 0.01 mmHg. These detection ranges illustrate that the end-tidal carbon dioxide detection unit can cover the acquisition needs of relevant parameters during resuscitation; the specific detection range is determined by sensor selection and equipment calibration.

[0057] For example, during a resuscitation control cycle, parameters obtained by the end-tidal carbon dioxide detection unit are sent to the vital signs analysis unit. The vital signs analysis unit can compare these parameters with preset response conditions to determine whether they are within the preset response range or whether there is a trend change relative to the previous control cycle. This comparison result does not directly affect the actuator but is sent to the control module as part of the chest compression effect feedback information.

[0058] The blood oxygen saturation detection unit can acquire the patient's blood oxygen saturation parameters using photoplethysmography. In one configuration, the blood oxygen saturation detection range can be 0–100%, and the resolution can be 1%, 0.1%, or 0.05% (the blood oxygen saturation detection unit can distinguish changes in blood oxygen saturation at corresponding percentage intervals). This parameter is used to reflect changes in the patient's blood oxygen status during the current resuscitation process.

[0059] For example, when the blood oxygen saturation parameter does not meet the preset response conditions within a continuous resuscitation control cycle, the vital signs analysis unit generates chest compression effect feedback information based on this result. The control module then uses this feedback information in conjunction with the chest compression quality feedback to determine whether it is necessary to adjust the chest compression action or respiratory coordination action. If the blood oxygen saturation parameter recovers to the range corresponding to the preset response conditions, the control module can reduce the correction magnitude of the chest compression adjustment command and continue to monitor the feedback in the next cycle.

[0060] The cardiac output detection unit is used to acquire the patient's cardiac output parameters. In one configuration, the cardiac output detection unit can acquire cardiac output ICG-related parameters, which characterize the patient's circulatory perfusion or changes in cardiac output. Its detection range can be 0-10 L / min, 0-20 L / min, or 0-30 L / min, with corresponding resolutions of 0.1 L / min, 0.05 L / min, or 0.01 L / min (the cardiac output detection unit can distinguish changes in cardiac output to corresponding flow intervals). The specific combination of the detection range and resolution is determined by the actual equipment configuration and calibration results. The aforementioned range and resolution describe the parameter output format of the cardiac output detection unit; the specific detection method, installation location, and signal source are determined by the actual equipment configuration and calibration results. The cardiac output detection unit converts the acquired cardiac output-related signals into cardiac output parameters and sends them to the vital signs analysis unit. The vital signs analysis unit uses the cardiac output parameters to generate chest compression effect feedback information.

[0061] For example, after the cardiac output detection unit sends the acquired cardiac output parameters to the vital signs analysis unit, the vital signs analysis unit can compare them with preset response conditions. If there is a deviation between the cardiac output parameters and the preset response conditions, the control module associates this deviation with the compression depth or compression force deviation in the compression quality feedback information to determine whether the current adjustment direction is to maintain the original compression action, reduce the adjustment amplitude, or make compression adjustments if the air supply safety conditions permit.

[0062] In the vital signs analysis unit, at least one of the end-tidal carbon dioxide, blood oxygen saturation, and cardiac output parameters can be compiled into chest compression effect feedback information. To avoid directly controlling the resuscitation execution module based solely on a single instantaneous value, the vital signs analysis unit can perform interval judgment, trend judgment, or validity marking on each vital signs parameter according to preset response conditions, and send the judgment results to the control module.

[0063] The vital signs analysis unit can be implemented by an embedded data processor. This embedded data processor receives at least one of end-tidal carbon dioxide parameters, blood oxygen saturation parameters, and cardiac output parameters, and performs effectiveness judgment, interval comparison, and trend judgment on these parameters to generate chest compression effect feedback information. This chest compression effect feedback information can be output in the form of interval judgment results, trend judgment results, effectiveness markers, or chest compression effect evaluation results, and serves as the basis for the control module to correct the chest compression parameters.

[0064] For example, when one of the detection pathways for end-tidal carbon dioxide, blood oxygen saturation, and cardiac output is temporarily invalid, the vital signs analysis unit can mark that pathway as invalid and compile the parameters corresponding to the valid pathways into compression effectiveness feedback information. Upon receiving this information, the control module does not use the invalid pathway in critical adjustments, but instead forms conservative control based on the valid vital signs parameters and the compression quality parameters fed back by the real-time quality feedback module.

[0065] The control module may include a parameter calling unit, a deviation determination unit, a correlation processing unit, and an instruction generation unit. The control module can be implemented using a microcontroller, an embedded processor, or a control processing unit with data acquisition, parameter comparison, and instruction output capabilities. The control module is connected to the real-time quality feedback module, the compression effect feedback module, the air supply monitoring and alarm unit, the automatic compression unit, and the automatic breathing unit, respectively, to receive feedback parameters, determine deviation information parameters, and output resuscitation control instructions. The parameter calling unit stores or calls a set of preset compression parameters corresponding to the patient's body shape information; the deviation determination unit determines compression execution deviation information parameters and physiological response deviation information parameters; the correlation processing unit correlates compression quality feedback information and compression effect feedback information within the same resuscitation control cycle; and the instruction generation unit generates resuscitation control instructions based on the correlation processing results.

[0066] The preset compression parameter set may include initial compression depth parameters, initial compression frequency parameters, initial compression time parameters, or other control parameters related to chest compressions that correspond to the patient's body shape information. The preset compression parameter set can be sourced from equipment calibration results, operating procedures, manufacturer data, historical statistics, or rules preset by medical personnel. After determining the initial compression parameters based on the patient's body shape information, the control module does not execute these initial parameters in a fixed manner, but rather adjusts them based on deviation information parameters observed during resuscitation.

[0067] The preset compression parameter set can be pre-stored in the local memory of the control module, or it can be synchronized to the local memory of the control module by the remote terminal or cloud data terminal when the wireless communication unit is communicating normally with the remote terminal or cloud data terminal, and then called by the control module. When performing resuscitation control, the control module determines the initial compression parameters based on the locally available preset compression parameter set, so as to avoid affecting the local resuscitation control process when communication is interrupted.

[0068] For example, after medical staff enter the patient's body shape information before starting the device, the parameter retrieval unit retrieves the corresponding initial compression parameters from the preset compression parameter set. If the patient's body shape information is not available, the control module can retrieve the default initial parameters or wait for confirmation from the medical staff. After the initial compression parameters enter the deviation determination unit, they are used together with the feedback information output by the real-time quality feedback module and the compression effect feedback module to determine the current resuscitation status.

[0069] In one specific deviation determination method, the control module can first determine the direction and degree of deviation of each feedback parameter relative to its corresponding preset conditions. When a feedback parameter is within the preset range, the control module marks the parameter as normal; when the feedback parameter is below the preset lower limit, the control module marks the parameter as below the target state; when the feedback parameter is above the preset upper limit, the control module marks the parameter as above the target state. The upper and lower limits of the aforementioned preset range are determined by equipment calibration results, operating procedures, historical statistical results, or preset conditions confirmed by medical staff.

[0070] The control module can first normalize the deviation of a single parameter from a preset range. The calculation rule can be expressed as follows:

[0071]

[0072] in, This is a function to calculate the degree of deviation of the parameter from its corresponding preset range. For parameters Relative to the preset range [ The degree of deviation; These are the compression quality parameters or vital sign parameters obtained during the current resuscitation control period; and These are the preset lower limit and preset upper limit for the parameter, respectively. The source of these limits can be the equipment calibration results, operating procedures, historical statistical results, or preset conditions confirmed by medical staff. This is the normalized reference value corresponding to the parameter, determined by the range of the corresponding detection unit, the preset safety range width, or the calibration result. The output of this formula is used for subsequent calculations of pressure quality deviation and physiological response deviation; when the parameter is within the preset range, the deviation is zero; when the parameter is below or above the preset range, the deviation increases with the increase of the deviation amount.

[0073] In determining the press execution deviation information parameters, the deviation determination unit can generate press amplitude deviation, press frequency deviation, press timing deviation, and press state deviation based on press depth-related parameters or press force-related parameters, press frequency parameters, press time parameters, and press state parameters, respectively. When any of these deviations reaches the corresponding preset condition, the control module writes the deviation into the press execution deviation information parameters. When multiple deviations exist simultaneously, the control module determines the priority of each deviation based on the equipment calibration results, operating procedures, or on-site trial operation configuration, and prioritizes handling deviations that are abnormal in press state, abnormal in gas source safety, or exceed the safety range.

[0074] The calculation rule for the pressing mass deviation value can be expressed as follows:

[0075]

[0076] in, This is the compression quality deviation value, used to characterize the degree of deviation of the current chest compression action from the preset set of compression parameters; The parameters related to the pressing depth are determined by the displacement detection results in the pressing detection unit or the equipment calibration conversion results; The pressure-related parameters are obtained from the force-measuring element in the pressure detection unit; The pressing frequency parameter is obtained by the frequency detection unit; The press timing feedback parameter is generated from at least one of the press time parameter, pause time parameter, and total running time parameter. The press status is marked by the status detection unit. When the press status meets the preset operating conditions, a lower mark value can be used, and when there is a pause, no start, or execution abnormality, a higher mark value is used. These are the preset press parameter range boundaries for the corresponding parameters; As the weighting coefficients for the corresponding parameters, the control module has a preset weighting allocation logic for each parameter based on the effectiveness of resuscitation. When the compression detection unit only acquires compression depth-related parameters or only acquires compression force-related parameters, the deviation terms corresponding to the unacquired parameters are not included in the calculation of the compression quality deviation value.

[0077] Due to the depth of pressure and pressing frequency It is the core mechanical indicator that determines the hemodynamic effect of cardiopulmonary resuscitation. The control module can configure corresponding weights for compression depth-related parameters, compression force-related parameters, compression frequency parameters, compression timing feedback parameters, and compression status markers based on equipment calibration results, operating procedures, or medical confirmation rules.

[0078] variable As a state penalty, when the state detection unit confirms that the mechanical mechanism is operating normally... The value is 0; when mechanical jamming, failure to start, or unexpected pause occurs, The value is 1, and the weighting coefficient is... It will increase the total deviation value The status detection unit writes the corresponding status into a press status flag. The control module treats this status as an execution exception according to a preset priority and outputs an execution exception alarm. The calculated... It enters the associated processing unit, which is used to generate resuscitation control commands together with the compression effect feedback information.

[0079] For example, when the pressing frequency parameter is lower than the preset range but the pressing status parameter shows that the mechanical pressing device is still in operation, It mainly reflects frequency deviation; when the status detection unit indicates that the mechanical pressing device is in a paused state, With the corresponding increase in deviation contribution, the control module can prioritize outputting execution abnormality alarms or pause time prompts, rather than directly increasing the pressing intensity.

[0080] In determining the physiological response deviation information parameters, the deviation determination unit can generate a physiological response deviation based on at least one of the end-tidal carbon dioxide parameter, blood oxygen saturation parameter, and cardiac output parameter. When the vital signs parameter does not meet the preset response conditions, the control module writes the judgment result corresponding to the parameter into the physiological response deviation information parameters; when the vital signs parameter meets the preset recovery conditions, the control module no longer uses it as the basis for increasing chest compressions, but instead enters the recovery confirmation, stop chest compressions, or dormancy judgment process.

[0081] The calculation rule for physiological response deviation can be expressed as:

[0082]

[0083] in, Physiological response deviation value, used to characterize the degree of deviation of the patient's physiological response state from the preset response conditions during the current chest compression process; The end-tidal carbon dioxide parameter is obtained by the end-tidal carbon dioxide detection unit. This is a blood oxygen saturation parameter, obtained by the blood oxygen saturation detection unit; This is a cardiac output parameter, obtained by the cardiac output detection unit; The parameter boundaries corresponding to the preset response conditions can be derived from operating procedures, historical statistical results, equipment calibration, or medical confirmation. These are the weights corresponding to the physiological response parameters.

[0084] In the physiological mapping logic of vital signs, end-tidal carbon dioxide parameters Displacement parameters Directly and positively correlated with the actual cardiac output and lung perfusion level generated by chest compressions, therefore corresponding to the weight. and It was configured as the primary decision weight; while blood oxygen saturation It has physiological lag, and its weight It is configured as a secondary auxiliary weight. When the patient's vital signs parameters meet the preset recovery conditions or show a recovery trend, the control module can combine the compression quality deviation value and the air supply safety status to reduce the compression-related control amount, maintain the current control amount, or enter the recovery confirmation process.

[0085] The weights corresponding to each physiological response parameter can be derived from on-site trial operation configurations, expert experience configurations, or historical data statistical results. The calculated... Enter the correlation processing unit, which is used to determine the current recovery status together with the compression quality deviation value.

[0086] For example, when the end-tidal carbon dioxide and blood oxygen saturation parameters are both within the range corresponding to the preset response conditions, but the cardiac output parameter has not yet obtained valid data, the control module can generate compression effect feedback information based on the valid parameters and mark the cardiac output branch as invalid. When multiple vital sign parameters deviate from the preset response conditions, the correlation processing unit can increase the influence weight of physiological response deviation in the resuscitation control command, but it still needs to combine the gas supply safety status to make the execution permission judgment.

[0087] In the correlation processing unit, the control module can correlate the compression execution deviation information parameters and physiological response deviation information parameters within the same resuscitation control cycle. If a compression execution deviation exists but the physiological response deviation does not reach the preset abnormal condition, the control module can generate a small-amplitude compression adjustment command; if both the compression execution deviation and the physiological response deviation reach the corresponding preset conditions, the control module generates a resuscitation control command provided that the air supply safety status meets the preset safety conditions; if the compression effect feedback information meets the preset recovery conditions, or the control module receives a spontaneous breathing recovery confirmation signal, the control module generates a control command to stop compressions and enter a hibernation or standby state.

[0088] The calculation rule for the current recovery status deviation information parameter can be expressed as:

[0089]

[0090] in, This refers to the deviation information parameters of the current recovery status; This represents the deviation value of the pressing mass. This represents the physiological response deviation value. The weighted correlation between compression quality deviation and physiological response deviation can be derived from equipment calibration, operating procedures, or medical personnel configuration. The formula is applicable only if at least one of the real-time quality feedback module and the compression effect feedback module has a valid feedback branch.

[0091] The The overall deviation intensity is used to represent the current resuscitation status, not the adjustment direction alone; the control module determines the adjustment direction of the next resuscitation control cycle based on the deviation direction of the compression parameters from the preset compression parameter range, the change direction of the vital signs parameters from the preset response conditions, the preset recovery conditions, and the gas source safety status.

[0092] When the vital signs detection branch in the compression effect feedback module is invalid, the control module degrades the associated processing through internal adaptive logic: for example, when the physiological feedback branch is invalid, conservative control is performed based on compression quality feedback; the system enters a single-parameter safe execution mode that relies solely on the mechanical closed loop, cutting off the interference of physiological feedback on the compression command; when the compression quality feedback branch is abnormal, the control module does not directly generate adjustment commands to enhance compression, but instead restricts or stops outputting compression adjustment commands to the automatic compression unit, and outputs an execution abnormality alarm through the resuscitation execution module, causing the system to enter a conservative processing state.

[0093] For example, when Higher but When the pressure is low, it indicates that the mechanical compression action deviates from the preset parameters, but the patient's physiological response does not show a significant deviation, and the control module can generate a small-amplitude compression adjustment command; when and When both are relatively high, the control module can generate a resuscitation control command, while taking the gas source safety status as a prerequisite for execution; when When the preset recovery conditions are met or the control module receives a confirmation signal of spontaneous breathing recovery, the control module generates control commands to stop chest compressions and enter a dormant state.

[0094] Among them, the pressing quality deviation value Used to characterize the degree of deviation of the current chest compression action from preset compression parameters, physiological response deviation value This parameter is used to characterize the degree of deviation of a patient's vital signs parameters from preset response conditions; it represents the current resuscitation status deviation. Used to allow the control module to determine the direction of compression adjustment for the next resuscitation control cycle. The control module, based on... The changing trend determines whether to maintain the current pressing parameters, increase the pressing-related control quantity, decrease the pressing-related control quantity, or output an alarm message.

[0095] In the instruction generation unit, the control module can generate compression adjustment instructions and breathing coordination instructions based on deviation information parameters. Compression adjustment instructions are used to adjust at least one of the following: compression depth-related control quantity, compression force-related control quantity, compression frequency control quantity, or compression speed control quantity. Breathing coordination instructions are used to control the automatic breathing unit to perform breathing assistance actions under preset coordination conditions. If the calculated or determined adjustment direction would cause the target compression parameter to exceed the preset safety range, the control module will limit the corresponding control quantity or maintain the original control quantity; if the air source safety status does not meet the preset safety conditions, the control module will restrict or stop the execution of the compression adjustment instructions.

[0096] The control module can correct the pressing parameters according to the amplitude limiting correction rule, and the calculation rule can be expressed as follows:

[0097]

[0098] in, The target compression parameter for the next resuscitation control cycle can be one of the following: compression depth-related control quantity, compression force-related control quantity, compression frequency control quantity, or compression speed control quantity. Set the target pressure parameters for the current recovery control cycle; These are parameter correction factors, which can be derived from equipment calibration, on-site trial operation, or operating procedures. The adjustment direction marker is used to indicate the direction in which the control module adjusts the current target pressing parameter; when it is necessary to increase the corresponding target pressing parameter, Take a positive flag; when it is necessary to reduce the corresponding target press parameter. Take the reverse marker; when maintaining the current target press parameters, Take the value of zero; This refers to the deviation information parameters of the current recovery status; and These are the preset lower safety limit and preset upper safety limit corresponding to the parameter, which can be derived from equipment structural limitations, operating procedures, manufacturer information, or medical confirmation. This indicates that the calculation results will be limited to a preset safety range. The calculated... Enter the resuscitation execution module, which is used to generate the compression adjustment instructions for the automatic compression unit.

[0099] In the same calculation instance, , , , and The target pressing parameters should correspond to the same type of target pressing parameters; when the target pressing parameter is a pressing depth-related control quantity, the above parameters adopt the corresponding depth control dimension; when the target pressing parameter is a pressing force-related control quantity, pressing frequency control quantity, or pressing speed control quantity, the above parameters adopt the corresponding control dimension respectively.

[0100] For example, when the control module according to The calculation yields the press frequency control value for the next cycle, but if this control value exceeds the preset safety limit, The control module restricts the pressure to a preset safety range and only outputs the restricted pressure adjustment command to the automatic pressing unit; if the air source safety status does not meet the preset safety conditions before the adjustment command is executed, the command is restricted or stopped from being executed.

[0101] In the resuscitation execution module, the gas source monitoring and alarm unit may include a filter, a pressure sensor, a first overpressure protector, and a second overpressure protector. The filter can be a HEPA filter for filtering the gas source; the pressure sensor acquires the gas source pressure parameters; the first and second overpressure protectors correspond to different preset overpressure conditions, forming tiered overpressure protection. In one configuration, the pressure sensor's measurement range can be 0~10 PSI, and the set pressures of the first and second overpressure protectors can be 30 PSI and 40 PSI, respectively; in another configuration, the pressure sensor's measurement range can be 0~15 PSI, and the set pressures can be 35 PSI and 45 PSI, respectively; in yet another configuration, the pressure sensor's measurement range can be 0~20 PSI, and the set pressures can be 40 PSI and 50 PSI, respectively. The above values ​​are implementation parameters listed in the documentation; specific thresholds are determined by equipment calibration, manufacturer documentation, or operating procedures.

[0102] In one method for determining the safety status of a gas source, the control module can generate a gas source safety permit flag based on gas source pressure parameters and graded overpressure protection status. The calculation rule can be expressed as follows:

[0103]

[0104] in, Mark the gas source safety status; The air source pressure parameters are obtained by the pressure sensor; The preset overvoltage threshold is the value corresponding to the first overvoltage protector. This is the preset overvoltage threshold corresponding to the second overvoltage protector, and Higher than , and The source can be equipment calibration results, manufacturer information, or operating procedures.

[0105] The gas source safety status marker Not included in the pressing quality deviation value Physiological response deviation value Or the current recovery status deviation information parameter The calculation is not used as a condition for granting permission to execute the resuscitation control order: when hour, The control module determines that the gas source safety status meets the preset safety conditions and allows the execution of press adjustment commands within the preset safety range; when hour, When the control module determines that the gas source safety status does not meet the preset safety conditions, it restricts the enhanced pressing function and triggers an alarm; when , When the control module determines that the air source safety status does not meet the preset safety conditions, it stops chest compressions and puts the system into a conservative processing state.

[0106] In this embodiment, the control module first passes through Calculate the degree of deviation of each individual feedback parameter from its corresponding preset range; then, generate a press quality deviation value based on press depth-related parameters, press force-related parameters, press frequency parameters, press timing feedback parameters, and press status markers. Physiological response deviation values ​​are generated based on end-tidal carbon dioxide parameters, blood oxygen saturation parameters, and cardiac output parameters. After that, the control module will and Correlation of parameters to form the current recovery status deviation information And combined with adjusting direction markings Determine the target pressor parameters for the next recovery control cycle. After the target pressing parameters are formed, the control module then checks the gas source safety status. Determine whether the press adjustment command corresponding to the target press parameter is allowed to be executed.

[0107] For example, when the pressure sensor detects that the gas source pressure has not reached the first overpressure protection condition, the control module allows the automatic pressing unit to receive pressing adjustment commands; when the pressure sensor detects that the gas source pressure has reached the first overpressure protection condition, the system outputs a level one alarm and locks at the logic layer. The system calculates positive pressure to limit further increases in chest compression intensity, while simultaneously triggering an overpressure fallback mechanism: the control module forcibly sets the target compression depth command to a preset safe lower limit corresponding to the patient's current body size. Through the graded protection action corresponding to the first overpressure protector or the control module's limiting processing, the system falls back to the currently permissible safe control level. When the air supply pressure returns to within the preset safe conditions, the control module allows the regeneration of compression adjustment commands based on feedback from the next resuscitation control cycle. When the second overpressure protection condition is reached, the system stops or limits the automatic compression unit from continuing chest compressions and sends an alarm message to the wireless communication unit. Before this state is lifted, the control module does not execute parameter adjustment commands to increase compression intensity, compression speed, or compression frequency.

[0108] The automatic chest compression unit may include a compression depth adjustment valve, a compression speed adjustment valve, and a mechanical compression device. The mechanical compression device may be a piston-type mechanical compression device. The compression depth adjustment valve and the compression speed adjustment valve adjust the chest compression action according to the compression adjustment commands from the control module. The mechanical stroke or valve adjustment stroke of the compression depth adjustment mechanism can be determined based on the equipment calibration results, and the adjustment range of the compression depth adjustment mechanism includes configurations such as 5~50cm, 10~60cm, and 20~70cm. The relevant control parameters for the effective compression depth applied to the human chest should be determined by the control module based on a preset set of compression parameters, compression detection results, and equipment calibration relationships, and limited within a preset safety range.

[0109] The pressing speed adjustment mechanism is used to adjust the reciprocating speed of the mechanical pressing device. Its specific adjustment range is determined by the mechanical structure, air source pressure and equipment calibration results. The adjustment range of the pressing speed adjustment valve includes configurations such as 5~50cm / s, 10~60cm / s, and 20~70cm / s.

[0110] For example, when the control module generates a press adjustment command instructing an increase in the press frequency, the press speed regulating valve in the automatic press unit adjusts the reciprocating speed of the mechanical press device accordingly. When the control module generates a press adjustment command instructing a correction of the press depth-related control value, the press depth regulating valve adjusts the stroke or corresponding control value of the mechanical press device accordingly. After the adjustment is completed, the press detection unit and the frequency detection unit reacquire the actual press parameters and send the new press quality feedback information back to the control module for use in the next recovery control cycle.

[0111] In the automated breathing unit, the unit performs respiratory assistance actions according to preset coordination conditions based on respiratory coordination commands. The automated breathing unit can use a bag-type breathing mask with a bag volume of 5L, 8L, or 10L, and the bag material can be a transparent plastic film. The automated breathing unit connects to the control module and works in conjunction with the automatic chest compression unit to ensure that respiratory assistance actions and chest compression actions are performed according to preset coordination conditions.

[0112] For example, when the control module determines, based on the compression status parameters, that the mechanical compression device is in a compression interval, pause phase, or a preset respiratory coordination window, the control module sends a respiratory coordination command to the automated breathing unit (ABS), causing the ABS to perform respiratory assistance. The preset respiratory coordination window can be determined by the compression status parameters, compression time parameters, pause time parameters, and the operating status of the mechanical compression device. The control module only outputs the respiratory coordination command when the compression interval, pause phase, or operating status meets the preset respiratory assistance conditions. When the mechanical compression device is in a state that does not meet the preset coordination conditions, the ABS does not perform or delays the respiratory assistance action and feeds back the unexecuted or delayed execution status to the control module to avoid incoordination between the respiratory assistance action and the chest compression action. After the respiratory assistance action is executed, the patient's vital signs continue to be collected by the compression effect feedback module and transmitted back to the control module.

[0113] The wireless communication unit can transmit data with the remote terminal via 5G, Wi-Fi, or Bluetooth. The specific communication distance is determined by the selection of the wireless communication module, the communication environment, and equipment testing results. The wireless communication unit sends at least one of the following parameters to the remote terminal: compression quality parameters, patient vital signs parameters, and gas supply quality parameters. It also receives parameter adjustment commands from the remote terminal. Gas supply quality parameters include at least gas supply pressure parameters, gas supply filtration status, or overpressure protection status. The communication distance can be 50 meters, 100 meters, or 150 meters. The remote terminal can be a PC running diagnostic or monitoring software to receive operational data and alarm information uploaded by the system. After receiving the data from the wireless communication unit, the remote terminal can display the patient vital signs parameters, compression quality parameters, gas supply quality parameters, and alarm information in real time for remote diagnostic reference by medical personnel. With appropriate permissions, the remote terminal can generate parameter adjustment commands based on the received monitoring data and send these commands to the control module. Before executing the parameter adjustment command, the control module first determines the gas supply safety status, the preset safety range, and the current recovery or sleep status.

[0114] For example, when the control module detects abnormal air supply pressure, abnormal chest compression status, or vital sign parameters meeting preset abnormal conditions, the wireless communication unit sends alarm information and relevant parameters to the remote terminal. If the remote terminal sends a parameter adjustment command, the control module first determines whether the air supply safety status meets preset safety conditions before executing the command. The control module also performs a consistency check between the parameter adjustment command and the current preset chest compression parameter set, chest compression quality feedback information, and chest compression effect feedback information. When the air supply safety status does not meet the preset safety conditions, the control module will not execute the remote parameter adjustment command that would increase the intensity of chest compressions, but will instead maintain the alarm, limit execution, or stop execution. When the remote parameter adjustment command conflicts with the local air supply safety status, preset safety range, or recovery / sleep judgment result, the control module prioritizes the local safety judgment result and sends the state of not executing the remote parameter adjustment command as alarm information or operation record to the remote terminal.

[0115] During the feedback update and hibernation process, after the resuscitation execution module executes the resuscitation control command, the real-time quality feedback module reacquires the compression quality feedback information, and the compression effect feedback module reacquires the compression effect feedback information. The control module updates the deviation information parameters based on the reacquired compression quality and effect feedback information, and generates the resuscitation control command for the next resuscitation control cycle based on the updated deviation information parameters. The control module is also used to record, statistically analyze, or store the compression quality parameters, patient vital signs parameters, gas supply quality parameters, resuscitation control commands, alarm information, and hibernation or standby status generated within each resuscitation control cycle. The recorded, statistical, or stored results can be used for local operational status review or transmitted to a remote terminal via the wireless communication unit for status display and subsequent diagnostic reference. Thus, the system operates in the sequence of feedback, comparison, control, execution, and refeedback within each resuscitation control cycle.

[0116] For example, after the automatic chest compression unit executes the compression adjustment command in the current cycle, the compression detection unit re-acquires compression depth or compression force parameters, the frequency detection unit re-acquires compression frequency parameters, and the end-tidal carbon dioxide detection unit and blood oxygen saturation detection unit re-acquire the corresponding vital sign parameters. The control module updates the deviation information parameters with the new feedback information. If the chest compression effect feedback information meets the preset recovery conditions, or if the control module receives a spontaneous breathing recovery confirmation signal, the control module controls the resuscitation execution module to stop chest compressions and puts the system into a dormant or standby state. The spontaneous breathing recovery confirmation signal can be input by medical personnel through the control interface or through a confirmation port connected to the system. The preset recovery conditions can be obtained by comparing at least one of the end-tidal carbon dioxide parameters, blood oxygen saturation parameters, and cardiac output parameters with recovery judgment conditions formed by medical personnel confirmation rules, operating procedures, or equipment calibration results. If no recovery confirmation signal is obtained and the chest compression effect feedback information does not meet the preset recovery conditions, the control module does not enter a dormant state but continues to update feedback and generate control commands according to the next resuscitation control cycle.

[0117] In one specific configuration, the control module may employ an ARM Cortex-A53, ARM Cortex-A55, or ARM Cortex-A78 processor, and configure corresponding memory and operating system according to the device's processing capacity, communication requirements, and display requirements; the aforementioned processor model, clock frequency, memory capacity, and system version are merely examples of specific hardware configurations for the control module and are not intended as necessary limitations for implementing this invention.

[0118] In summary, the intelligent cardiopulmonary resuscitation (CPR) machine system provided in this embodiment of the invention, through a real-time quality feedback system, can record, statistically analyze, and store parameters such as compression depth, compression frequency, compression time, pause time, total running time, and compression status in real time, achieving full monitoring of the CPR process and improving the controllability and traceability of compression quality. By integrating real-time monitoring and feedback parameters of multiple vital signs such as end-tidal carbon dioxide, blood oxygen saturation, cardiac output, and ICG, the compression effect feedback system can monitor the CPR effect in real time and enable the system to adjust compression parameters in real time according to the patient's physiological state, avoiding uneven compression intensity or insufficient rebound caused by manual operation, which is conducive to improving the effectiveness of CPR.

[0119] Through wireless modules (such as 5G, WIFI, Bluetooth, etc.), remote communication with emergency units such as emergency centers is achieved, enhancing the portability of the equipment and enabling CPR operations to be performed even in confined spaces. It also allows for remote monitoring and optimized treatment of patients. The integrated design of a real-time quality feedback system and a compression effect feedback system allows the equipment to automatically adjust compression strategies based on individual patient differences, improving the accuracy and applicability of CPR and overcoming the limitations of traditional manual operation. Real-time recording and storage of various parameters also facilitates subsequent diagnosis and treatment by doctors, improving the overall efficiency of treatment and the quality of patient recovery.

[0120] The intelligent cardiopulmonary resuscitation (CPR) machine system, which integrates real-time quality feedback and compression effect feedback, can not only ensure compression quality but also adjust compression parameters in real time according to the patient's physiological state, thereby improving the efficiency and effectiveness of CPR. At the same time, the system has remote communication capabilities, enabling remote monitoring, information exchange, and optimized treatment.

[0121] The above description is merely a preferred embodiment of the technical solution of the present invention and is not intended to limit the scope of protection of the present invention.
