Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an integrated cardiopulmonary resuscitation device, system and equipment thereof. Background Art
[0002] Cardiopulmonary resuscitation can save patients with cardiac arrest. According to the 2015 AHA Cardiopulmonary Resuscitation Guidelines, the guidelines recommend that you perform cardiopulmonary resuscitation (chest compressions and artificial respiration) as soon as possible, and obtain a nearby AED (automatic external defibrillator) to minimize interruptions in compressions; once the AED is obtained, perform an electrocardiogram and defibrillation on the patient as soon as possible. Once cardiac arrest occurs, if it is not promptly rescued and resuscitated, it will cause irreversible damage to the patient's brain and other important organs and tissues of the people in distress after 4 to 6 minutes. Therefore, cardiopulmonary resuscitation after cardiac arrest must be performed immediately on the scene to win the most precious time for further rescue and even saving the lives of the patients with cardiac arrest.
[0003] At present, there are corresponding emergency equipment for sudden cardiac arrest on the market, but most of them work independently, such as cardiopulmonary resuscitation machines, AED defibrillators, ventilators, monitors, etc. When used together, it is difficult for the equipment to work together, the operation of the equipment is still too cumbersome, the quality of cardiopulmonary resuscitation is not high, and the success rate of treatment is almost the same as the success rate of manual compression. Moreover, the scale of the equipment used together will become huge, making it heavy and inconvenient to use. In particular, it is extremely inconvenient for out-of-hospital scenes such as ambulances, which ultimately leads to cumbersome operation of emergency equipment, loss of precious rescue time, poor emergency treatment effect, and even harm to patients.

BRIEF DESCRIPTION OF THE DRAWINGS
[0018] Figure 1 , Figure 2 It is a three-dimensional structural schematic diagram of a cardiopulmonary resuscitation trolley; Figure 3 for Figure 1 Schematic diagram of the internal structure of the middle box; Figure 4 for Figure 3 Schematic diagram of the storage location of the compression device, respiratory device, defibrillator electrodes, and monitoring accessories; Figure 5 The figure is a schematic diagram of the host composition. DETAILED DESCRIPTION
[0019] Combine the following Figure 1-Figure 5 The present invention is described in further detail.
[0020] The integrated cardiopulmonary resuscitation device comprises an integrated host 10, a pressing device 20, a respiratory device 30, a defibrillation electrode 40 and a monitoring accessory 50. The integrated host 10 has a built-in central control module 11, a cardiopulmonary resuscitation module 12, a respiratory module 13, a defibrillation module 14 and a monitoring module 15. The pressing device 20 is connected to the cardiopulmonary resuscitation module 12, the respiratory device 30 is connected to the respiratory module 13, the defibrillation electrode 40 is connected to the defibrillation module 14, and the monitoring accessory 50 is connected to the monitoring module 15. The integrated host 10 controls the pressing device 20, the respiratory device 30 and the defibrillation electrode 40 to perform pressing, ventilation and defibrillation operations respectively according to the patient's physiological signal collected by the monitoring accessory 50. The connection method is, for example, plug-in matching.
[0021] Cardiopulmonary resuscitation is based on the mechanical compression and mechanical ventilation of the cardiopulmonary resuscitation machine and ventilator to increase the oxygenated blood supply to the patient of cardiac arrest, and ultimately promote the patient to restore autonomous blood circulation and respiratory circulation. In addition, during cardiopulmonary resuscitation, defibrillation operations may be required to correct severe arrhythmias to restore cardiac pacing rhythm. At the same time, the monitor is required to provide the patient's physiological information in real time to help doctors determine the treatment strategy and judge the timing of withdrawal. In other words, the working strategy and treatment effect of cardiopulmonary resuscitation depend on the information coordination and work integration of the cardiopulmonary resuscitation machine, ventilator, defibrillator, and monitor. However, in the prior art, cardiopulmonary resuscitation machines, ventilators, defibrillators, and monitors work independently, that is, their own independent hosts and devices are responsible for physiological signal acquisition, processing, judgment, feedback, control and execution actions (taking the defibrillator as an example, it includes a monitoring part to determine the type of arrhythmia, and a control circuit to determine the timing of defibrillation, defibrillation waveform and defibrillation parameters, etc.). In this case, the devices cannot coordinate with each other on their own, resulting in structural redundancy and information asynchrony. At the same time, the adjustment of strategies between devices depends on the judgment of medical workers. Due to the different medical skills and the problem that manual judgment will delay the adjustment timing, it may affect the life-saving results under the device combination strategy.
[0022] In the above scheme, cardiopulmonary resuscitation, breathing, defibrillation, and monitoring modules are organically combined together, and each part is connected to the central control module 11 as a module, and the central control module 11 is used as the control center. The control center uniformly dispatches and manages, so that the modules work in coordination, realize the functions of each module, and avoid the modules being independent and affecting each other's work efficiency, thereby forming a complete closed-loop system, and can effectively reduce the time waste during emergency treatment, improve emergency treatment efficiency, and is expected to provide patients with the best device treatment strategy.
[0023] The above-mentioned numerous modules are all integrated into the host 10, and the control of each module is all realized by the same central control module 11, which can reduce the setting of components and greatly reduce the size of the device. The pressing device 20, the respiratory device 30, the defibrillation electrode 40 and the monitoring accessory 50 can be plugged into the interface of the corresponding module on the integrated host 10 to form a complete device when in use. When stored normally, the pressing device 20, the respiratory device 30, the defibrillation electrode 40 and the monitoring accessory 50 are separated from the integrated host 10 for easy carrying.
[0024] Since all the modules are built into the integrated host 10, the volume of the integrated host 10 is relatively large, so the positions of the modules need to be arranged reasonably. The specific structure is as follows: the integrated host 10 includes a shell 16, the shell 16 has a receiving cavity, the display 17 is fixed in the receiving cavity, the back of the display 17 is fixedly connected to the central control module 11, and the shell 16 on the periphery of the central control module 11 is provided with multiple installation slots, the cardiopulmonary resuscitation module 12, the respiratory module 13, the defibrillator module 14 and the monitoring module 15 are fixed in the installation slots and electrically connected to the central control module 20, and each module is provided with an exposed interface connected to the accessories and the interfaces do not interfere with each other. As a cardiopulmonary resuscitation device, it is indispensable to display the patient's relevant physiological information. Therefore, the display 17 is first set in the receiving cavity on one side of the shell 16 for the operator to observe. The central control module 11 is set in the middle area on the back of the display 17, and then the cardiopulmonary resuscitation module 12, the breathing module 13, the defibrillation module 14 and the monitoring module 15 are distributed around the central control module 11. On the one hand, they can be directly electrically connected to the central control module 11, and on the other hand, the interfaces on these modules can be arranged in a staggered manner to ensure sufficient space for connecting peripherals. In addition, the heat dissipation problem of each module needs to be considered, so a heat dissipation grille and other structures are also set on the shell 16.
[0025] A self-feedback cardiopulmonary resuscitation system, comprising: The monitoring module 15 is connected to the monitoring accessory 50 to collect the patient's physiological signals and feed them back to the central control module 11; The cardiopulmonary resuscitation module 12 is connected to the pressing device 20, collects historical operation data of the pressing device 20 and feeds it back to the central control module 14; The breathing module 13 is connected to the breathing device 30, collects historical operation data of the breathing device 30 and feeds it back to the central control module 11; The defibrillation module 14 is connected to the defibrillation electrode 40 and provides defibrillation energy, collects historical operation data of the defibrillation electrode 40 and feeds it back to the central control module 11; The central control module 11 is used to obtain target data, and evaluate the target resuscitation value that represents the cardiopulmonary function resuscitation of the patient in the current cycle according to the target data; determine the target control parameters that match the target resuscitation value, and control the target module to be executed according to the target control parameters.
[0026] The target data include the patient's physiological signals collected by the monitoring module 15 , and historical operating parameters of the cardiopulmonary resuscitation module 12 , the breathing module 13 and the defibrillation module 14 .
[0027] More specifically, the patient's physiological signals include at least one of an ECG (Electrocardiogram) signal, a blood oxygen signal, a body temperature signal, a blood pressure signal, a respiratory signal, a pulse signal, and a chest impedance signal; the historical operating data of the compression device 20 includes a compression frequency and / or a compression depth; the historical operating data of the respiratory device 30 includes a ventilation concentration and / or a ventilation frequency; and the historical operating data of the defibrillation electrode 40 includes a defibrillation waveform.
[0028] The current cycle refers to the current cardiopulmonary resuscitation cycle. The target resuscitation value is used to characterize the degree of cardiopulmonary resuscitation of the patient in the current cardiopulmonary resuscitation cycle. One implementation method of evaluating the target resuscitation value is: the resuscitation value corresponding to the target data can be determined according to a preset mapping relationship as the target resuscitation value. The preset mapping relationship is a mapping relationship between parameter data and resuscitation value. The parameter data includes physiological signals and operating parameters of the cardiopulmonary resuscitation system. The mapping relationship can be obtained by extrapolating and verifying a large amount of data in a simulation environment.
[0029] The target module to be executed currently is the cardiopulmonary resuscitation module 12 , the breathing module 13 or the defibrillation module 14 .
[0030] The target control parameters are control parameters used to control the target module. When the target module is a cardiopulmonary resuscitation module, the target control parameters may include compression depth, compression frequency, etc.; when the target module is a breathing module, the target control parameters may include ventilation concentration, ventilation frequency, etc.; when the target module is a defibrillator module, the target control parameters may include defibrillator waveform, etc.
[0031] Since the target control parameter is a control parameter that matches the target resuscitation value, controlling the target module according to the above target control parameter can make the operation of the target module adapt to the actual situation of the patient's current cardiopulmonary resuscitation, thereby realizing cardiopulmonary resuscitation system control that is adaptive to the patient.
[0032] The implementation method of determining the above target control parameter is: according to the corresponding relationship between the preset resuscitation value and the control parameter, the control parameter corresponding to the target resuscitation value is determined as the target control parameter.
[0033] The following three embodiments specifically describe the cardiopulmonary resuscitation module 12, the breathing module 13, and the defibrillation module 14, respectively: 1. Cardiopulmonary Resuscitation Module 12: The cardiopulmonary resuscitation module 12 includes a compression depth detection module and a compression frequency detection module, and the compression device 20 includes a servo motor, a chest strap and a compression head.
[0034] The central control module 11 specifically controls the cardiopulmonary resuscitation module 12 according to the following steps S11-S15: S11. Obtain first target data.
[0035] Among them, the above-mentioned first target data includes ECG signals, blood oxygen signals, historical ventilation concentrations, historical ventilation frequencies and historical defibrillation waveforms.
[0036] The above-mentioned historical ventilation concentration, historical ventilation frequency and historical defibrillation waveform are data before the current cycle in the whole process of cardiopulmonary resuscitation for the current patient. These data are historical data relative to the current cycle.
[0037] The first target data is collected by the monitoring module, the breathing module and the defibrillation module, and the first target data is stored in the memory. The central control module can read the first target data in the memory.
[0038] S12. Input the first target data into the first resuscitation assessment model to obtain the resuscitation value output by the first resuscitation assessment model as the first resuscitation value for the patient's cardiopulmonary function resuscitation in the current cycle.
[0039] The first resuscitation assessment model is a model for assessing the cardiopulmonary resuscitation of a patient obtained by pre-training an initial neural network model using the first sample data. The first sample data includes the ECG signal, blood oxygen signal, ventilation concentration, ventilation frequency and defibrillation waveform of the sample patient.
[0040] S13. Obtain a historical resuscitation value representing the cardiopulmonary function resuscitation of the patient in a historical period, and determine a first adjustment value of the historical compression depth and a second adjustment value of the historical compression frequency in the historical period based on a deviation value between the historical resuscitation value and the first resuscitation value.
[0041] The above historical resuscitation values are used to characterize the degree of resuscitation of the patient's cardiopulmonary function in the historical cycle. The historical cycle can be the cardiopulmonary resuscitation cycle of the preset length before the current cycle. For example, if the current cardiopulmonary resuscitation process has been implemented for the 10th cycle, then the historical cycle can be each single cycle before, or a combination of multiple cycles before.
[0042] The above-mentioned deviation value includes the deviation between the historical recovery value and the first recovery value, as well as the size relationship between the historical recovery value and the first recovery value. When the deviation value is a positive value, it indicates that the historical recovery value is greater than the first recovery value. When the deviation value is a negative value, it indicates that the historical recovery value is less than the first recovery value.
[0043] The implementation method for determining the first adjustment value and the second adjustment value is: according to the preset first corresponding relationship, the adjustment value of the pressing depth corresponding to the deviation value is determined as the first adjustment value, and according to the preset second corresponding relationship, the adjustment value of the pressing frequency corresponding to the deviation value is determined as the second adjustment value.
[0044] The first corresponding relationship is the corresponding relationship between the preset deviation value and the pressing depth adjustment value, and the second corresponding relationship is the corresponding relationship between the preset deviation value and the pressing frequency adjustment value.
[0045] S14. Obtain historical compression depth and compression frequency, adjust the historical compression depth according to the first adjustment value as the compression depth of the current cycle, and adjust the historical compression frequency according to the second adjustment value as the compression frequency of the current cycle.
[0046] The historical compression depth may be the compression concentration of the cycle adjacent to the current cycle, or the average value of the compression depths of the previous multiple cycles. The historical compression frequency may be the compression frequency of the cycle adjacent to the current cycle, or the average value of the compression frequency of the previous multiple cycles. The central control module may read the above historical compression depth and historical compression frequency from the memory.
[0047] The method for determining the compression depth of the current cycle is: calculating the sum of the first adjustment value and the historical compression depth as the compression depth of the current cycle; the method for determining the compression frequency of the current cycle is: calculating the sum of the second adjustment value and the historical compression frequency as the compression frequency of the current cycle.
[0048] S15. Control the cardiopulmonary resuscitation module according to the compression depth and compression frequency of the current cycle.
[0049] It can be seen that the first resuscitation value is based on the patient's physiological signals, such as ECG signals, blood oxygen signals, and historical operating data of the respiratory module and historical operating data of the defibrillator module. That is to say, in the cardiopulmonary resuscitation system provided in this embodiment, the cardiopulmonary resuscitation module, the respiratory module and the defibrillator module are considered to be related and mutually influential. When controlling the cardiopulmonary resuscitation module, the patient's cardiopulmonary resuscitation status is evaluated according to the historical operating data of the respiratory module and the defibrillator module and the patient's physiological parameters, thereby achieving high-precision adaptive control.
[0050] 2. Breathing module 13: The breathing module 13 includes a pressure detection module and a ventilation module; The central control module 11 specifically controls the breathing module 13 according to the following steps S21-S25: S21. Acquire second target data.
[0051] The second target data include ECG signals, respiratory signals, historical compression depths, historical compression frequencies and historical defibrillation waveforms.
[0052] The above-mentioned historical ventilation concentration, historical ventilation frequency and historical defibrillation waveform are data before the current cycle in the whole process of cardiopulmonary resuscitation for the current patient. These data are historical data relative to the current cycle.
[0053] The second target data is collected by the monitoring module, the cardiopulmonary resuscitation module, and the defibrillator module, and the second target data is stored in the memory. The central control module can read the second target data in the memory. S22. Input the second target data into the second resuscitation assessment model to obtain the resuscitation value output by the second resuscitation assessment model as the second resuscitation value for the cardiopulmonary function resuscitation of the patient in the current cycle.
[0054] The second resuscitation assessment model is a model for assessing the cardiopulmonary resuscitation of a patient obtained by pre-training the initial neural network model using the second sample data. The second sample data includes the ECG signal, respiratory signal, compression depth, compression frequency and defibrillation waveform of the sample patient.
[0055] S23. Obtain a historical resuscitation value representing the cardiopulmonary function resuscitation of the patient in the historical period, and determine a third adjustment value of the historical ventilation concentration and a fourth adjustment value of the historical ventilation frequency in the historical period based on the deviation value between the historical resuscitation value and the second resuscitation value.
[0056] The above historical resuscitation values are used to characterize the degree of resuscitation of the patient's cardiopulmonary function in the historical cycle. The historical cycle can be the cardiopulmonary resuscitation cycle of the preset length before the current cycle. For example, if the current cardiopulmonary resuscitation process has been implemented for the 10th cycle, then the historical cycle can be each single cycle before, or a combination of multiple cycles before.
[0057] The above-mentioned deviation value includes the deviation between the historical recovery value and the second recovery value, as well as the size relationship between the historical recovery value and the second recovery value. When the deviation value is a positive value, it indicates that the historical recovery value is greater than the second recovery value. When the deviation value is a negative value, it indicates that the historical recovery value is less than the second recovery value.
[0058] The implementation method for determining the third adjustment value and the fourth adjustment value is: according to the preset third corresponding relationship, the adjustment value of the ventilation concentration corresponding to the deviation value is determined as the third adjustment value, and according to the preset fourth corresponding relationship, the adjustment value of the ventilation frequency corresponding to the deviation value is determined as the fourth adjustment value.
[0059] The third corresponding relationship is the corresponding relationship between the preset deviation value and the ventilation concentration adjustment value, and the fourth corresponding relationship is the corresponding relationship between the preset deviation value and the ventilation frequency integral value.
[0060] S24. Obtain historical ventilation concentration and historical ventilation frequency, adjust the historical ventilation concentration according to the third adjustment value as the ventilation concentration of the current cycle, and adjust the historical ventilation frequency according to the fourth adjustment value as the ventilation frequency of the current cycle.
[0061] The historical ventilation concentration may be the ventilation concentration of the cycle adjacent to the current cycle, or the average value of the ventilation concentrations of the previous multiple cycles. The historical ventilation frequency may be the ventilation frequency of the cycle adjacent to the current cycle, or the average value of the ventilation frequency of the previous multiple cycles. The central control module may read the above historical ventilation concentration and historical ventilation frequency from the memory.
[0062] The ventilation concentration of the current cycle is determined by calculating the sum of the third adjustment value and the historical ventilation concentration as the ventilation concentration of the current cycle; the ventilation frequency of the current cycle is determined by calculating the sum of the fourth adjustment value and the historical ventilation frequency as the ventilation frequency of the current cycle.
[0063] S25. Control the cardiopulmonary resuscitation module according to the ventilation concentration and ventilation frequency of the current cycle.
[0064] It can be seen that the second resuscitation value is based on the patient's physiological signals, such as ECG signals, blood oxygen signals, and historical operating data of the cardiopulmonary resuscitation module and historical operating data of the defibrillator module. That is to say, in the cardiopulmonary resuscitation system provided in this embodiment, the cardiopulmonary resuscitation module, the respiratory module and the defibrillator module are considered to be related and mutually influential. When controlling the respiratory module, the patient's cardiopulmonary resuscitation status is evaluated according to the historical operating data of the cardiopulmonary resuscitation module and the defibrillator module and the patient's physiological parameters, thereby achieving high-precision adaptive control.
[0065] 3. Defibrillator module 14: The defibrillator module (14) comprises a high-voltage capacitor and a relay, and the high-voltage capacitor is connected to an external defibrillator electrode (40) via the relay to supply power to the defibrillator electrode (40); The central control module 11 specifically controls the defibrillator module 14 according to the following steps S31-S36: S31. Obtain third target data.
[0066] Among them, the above-mentioned third target data includes ECG signal, chest impedance signal, historical compression depth, historical compression frequency, historical ventilation concentration, and historical ventilation frequency.
[0067] The above-mentioned historical compression depth, historical compression frequency, historical ventilation concentration, and historical ventilation frequency are data before the current cycle during the entire process of cardiopulmonary resuscitation for the current patient. These data are historical data relative to the current cycle.
[0068] The third target data is collected by the monitoring module, the cardiopulmonary resuscitation module, and the breathing module, and the third target data is stored in the memory, and the central control module can read the third target data in the memory.
[0069] S32. Based on the ECG signal, determine whether the patient's heart rhythm is the preset defibrillation rhythm.
[0070] The preset defibrillation rhythm includes ventricular fibrillation rhythm and ventricular tachycardia rhythm. The implementation method of determining whether it is the preset defibrillation rhythm is: whether the ECG signal matches the signal template of the preset defibrillation rhythm, if it matches, it is determined that the patient's heart rhythm is the preset defibrillation rhythm, if not, it is determined that the patient's heart rhythm is not the preset defibrillation rhythm.
[0071] When it is determined that the patient's heart rhythm is the preset defibrillation rhythm, step S33 is executed; when it is determined that the patient's heart rhythm is not the preset defibrillation rhythm, the defibrillation module is not controlled.
[0072] S33. Input the third target data into the third resuscitation assessment model to obtain the resuscitation value output by the third resuscitation assessment model as the third resuscitation value for the patient's cardiopulmonary function resuscitation in the current cycle.
[0073] The third resuscitation assessment model is a model for assessing the cardiopulmonary resuscitation of a patient obtained by pre-training the initial neural network model using the third sample data. The third sample data includes the ECG signal, chest impedance signal, compression depth, compression frequency, ventilation concentration, and ventilation frequency of the sample patient.
[0074] S34. Obtain a historical resuscitation value representing the cardiopulmonary function resuscitation of the patient in the historical period, and determine a waveform parameter adjustment value of the historical defibrillation waveform of the historical period based on a deviation value between the historical resuscitation value and the third resuscitation value.
[0075] The above historical resuscitation values are used to characterize the degree of resuscitation of the patient's cardiopulmonary function in the historical cycle. The historical cycle can be the cardiopulmonary resuscitation cycle of the preset length before the current cycle. For example, if the current cardiopulmonary resuscitation process has been implemented for the 10th cycle, then the historical cycle can be each single cycle before, or a combination of multiple cycles before.
[0076] The above-mentioned deviation value includes the deviation between the historical recovery value and the third recovery value, as well as the size relationship between the historical recovery value and the third recovery value. When the deviation value is a positive value, it indicates that the historical recovery value is greater than the third recovery value. When the deviation value is a negative value, it indicates that the historical recovery value is less than the third recovery value.
[0077] The waveform parameter adjustment value may include an adjustment value of waveform amplitude, an adjustment value of frequency, an adjustment value of pulse width, etc. The implementation method of determining the waveform parameter adjustment value is: according to a preset fifth corresponding relationship, the adjustment value of the waveform parameter corresponding to the deviation value is determined as the waveform parameter adjustment value. The fifth corresponding relationship is a corresponding relationship between a preset deviation value and an adjustment value of the waveform parameter.
[0078] S35. Obtain a historical defibrillation waveform, and adjust the historical defibrillation waveform according to the waveform parameter adjustment value to serve as the defibrillation waveform of the current cycle.
[0079] The historical defibrillation waveform may be a defibrillation waveform of a cycle adjacent to the current cycle. The central control module may read the historical defibrillation waveform from the memory.
[0080] The defibrillation waveform of the current cycle is determined by calculating the sum of the waveform parameter adjustment value and the historical defibrillation waveform as the defibrillation waveform of the current cycle.
[0081] S36. Control the cardiopulmonary resuscitation module according to the ventilation concentration and ventilation frequency of the current cycle.
[0082] It can be seen that the third resuscitation value is based on the patient's physiological signals, such as ECG signals, blood oxygen signals, and the historical operating data of the cardiopulmonary resuscitation module and the historical operating data of the respiratory module. That is to say, in the cardiopulmonary resuscitation system provided in this embodiment, the cardiopulmonary resuscitation module, the respiratory module and the defibrillator module are considered to be related and mutually influential. When controlling the defibrillator module, the patient's cardiopulmonary resuscitation status is evaluated according to the historical operating data of the cardiopulmonary resuscitation module and the respiratory module and the patient's physiological parameters, thereby achieving high-precision adaptive control.
[0083] The system also includes a communication module 18, an energy management module 19, and a storage module 100. The communication module 18 can realize short-range and long-range communication. Short-range communication supports local wireless export of device data and local device configuration; long-range communication supports real-time communication between the device and a remote management system or platform, a central control platform of a 120 emergency center, and a real-time monitoring system for an ambulance, etc., so that remote system users, emergency platforms, professional doctors, etc. can grasp the rescue situation on site in real time. Since many modules are integrated in the integrated host 10, and all are controlled by the same central control module 11, the setting of the energy management module 19 is also very important. The energy management module 19 is connected to an external storage battery, controls the charging and discharging of the storage battery, and provides appropriate power for the pressing device 20 and the defibrillation electrode 50 to ensure the effectiveness of the cardiopulmonary resuscitation operation and the defibrillation operation. The storage module 100 may include RAM and ROM, wherein temporary data will be stored in RAM, and procedural key data will be stored in ROM for persistence, which is convenient for data backtracking and tracking.
[0084] As mentioned above, the entire cardiopulmonary resuscitation device is composed of five major parts: an integrated host 10, a pressing device 20, a respiratory device 30, a defibrillation electrode 40, and a monitoring accessory 50. In order to facilitate carrying, the applicant has proposed a portable cardiopulmonary resuscitation device, which also includes a chassis 60. The chassis 60 is provided with a accommodating and fixing portion for placing the pressing device 20, the respiratory device 30, the defibrillation electrode 40, and the monitoring accessory 50. The chassis 60 here can have a variety of structures, such as a suitcase. It only needs to place the pressing device 20, the respiratory device 30, the defibrillation electrode 40, and the monitoring accessory 50 in the box. The integrated host 10 can be provided with a handle for carrying directly, which is suitable for outdoor first aid situations. The chassis 60 can also be a case on which the integrated host 10 can be placed or inside it, which is easy to move and suitable for in-hospital first aid situations. In order to reduce the volume of the pressing device 20, the pressing device 20 here is preferably a third-generation cardiopulmonary resuscitation machine in which a pressing head is driven by a combination of a flexible chest strap + motor + screw nut mechanism to perform pressing. The integrated structure of the motor and the pressing head is fixed in the middle position above the flexible chest strap. The pressing device of this structure is small in size and can be easily placed in the accommodating cavity of the chassis 60. The monitoring accessories 50 include but are not limited to ECG lead wires, ECG electrodes, blood oxygen saturation probes, body temperature probes, blood pressure cuffs, respiratory devices, PPG sensors, Figure 4 Only some of the accessories are shown briefly.
[0085] As a preferred embodiment of the present invention, the chassis 60 is in the shape of a mobile trolley, including a box body 61. The integrated host 10 is detachably mounted on the top of the box body 61. A storage battery is provided at the upper part of the inner cavity of the box body 61. The power management module 90 of the integrated host 10 is electrically connected to the storage battery, which can store electrical energy and can power the cardiopulmonary resuscitation equipment in an off-electricity environment, thereby broadening the application scenarios of the equipment. An oxygen cylinder 62 is fixed on one side of the box body 61, and a door 63 is provided on the other side. The oxygen cylinder can be replaced, and the oxygen cylinder can be set outside the box body 11 or be exposed. Wheels 64 are also provided at the corner position of the bottom of the box body 61, and a handle 65 is also provided on the top side of the box body 61. The handle 65 is arranged to avoid the interface on the integrated host 10 for easy movement.
[0086] Since many modules are integrated in the integrated host 10, there are many kinds of accessories connected to the interfaces of the modules on the integrated host 10 during use, such as breathing masks, defibrillation electrodes, ECG electrodes, etc. In order to prevent the cables of various accessories from being in disarray, and also to enable each accessory to reach a designated position and maintain the best state during the working process, a plurality of mechanical arms 66 (only one is shown in the figure) are extended upward from the side of the box 61. The mechanical arm 66 is a multi-section steering tube, and a plurality of pipe clamps 67 (only two are shown in the figure) are provided on the steering tube. The positions of the accessories and their cables are fixed by the cooperation of the steering tube and the pipe clamp 67. On the one hand, the cables are neat, and on the other hand, it can be ensured that there will be no bending or blocking during the normal working process, which is particularly important for the trachea connected to the breathing mask.
[0087] The rescue process of the above portable cardiopulmonary resuscitation trolley is as follows: S1) Preliminary assessment of the patient's cardiac and respiratory arrest; S2) Place the compression device, respiratory device, defibrillation electrodes and monitoring accessories (ECG lead wires, ECG electrodes, blood oxygen saturation probe, temperature probe, blood pressure cuff, breathing circuit, PPG sensor) at the corresponding positions on the patient's body; S3) plugging the connection wires of the pressing device, the breathing device, the defibrillation electrodes and the monitoring accessories into the interfaces of the corresponding modules of the integrated host 10; S4) After monitoring that all accessories are installed in place, the monitoring component 50 collects the patient's ECG signal and pulse signal value monitoring module 50, and feeds back to the central control module 11 after processing; S5) The central control module 11 issues a command to control the pressing device 20 to perform chest compressions. The cardiopulmonary resuscitation module 12 detects the compression depth and compression frequency in real time and feeds back to the central control module 11. The central control module 11 adjusts the compression depth and compression frequency of the pressing device 20 in real time according to the patient's condition. S6) When the number of chest compressions reaches the set number of compressions, the central control module 11 issues an instruction to stop the chest compression operation and controls the ventilation module 13 to perform automatic ventilation operation. The central control module 11 adjusts the respiratory ventilation parameters according to the respiratory signal, blood oxygen signal and end-tidal carbon dioxide signal collected by the monitoring component 50; S7) the monitoring module 15 collects heart rhythm data to analyze abnormal heart rate. If the patient has not recovered spontaneous circulation, it determines whether electric shock defibrillation is required according to the analysis result of the heart rhythm data. S8) If it is determined that electric shock defibrillation is required, the defibrillation module 14 is used to control the current and perform electric shock on the patient through the defibrillation electrodes 40; S9) Monitor the ETCO2 value to indicate the recovery of spontaneous circulation. If spontaneous circulation has not been restored, repeat steps S5)-S8); if spontaneous circulation has been restored, continue to monitor blood pressure and blood oxygen signals until the instruction to remove the machine is given.
