Abstract
Description
Technical Field
[0001] The present invention relates to the field of smart medical technology, and in particular to an intelligent emergency procedure automation system. Background Art
[0002] First aid refers to the emergency treatment measures taken by witnesses or professional rescuers as soon as possible after a sudden illness or injury occurs, aiming to minimize damage and save lives until the arrival of professional medical teams. Among them, cardiopulmonary resuscitation (CPR) and the use of automated external defibrillators (AEDs) are the two key means of saving the lives of patients with cardiac arrest.
[0003] Cardiopulmonary resuscitation, as a basic first aid skill, aims to restore the patient's spontaneous circulation and respiratory function through continuous chest compressions and artificial respiration. When witnesses find that someone has suddenly fallen to the ground, lost consciousness and stopped breathing, it is extremely important to quickly start cardiopulmonary resuscitation. The automatic external defibrillator, as a medical device that can automatically analyze the heart rhythm and apply electric shock to restore the heart to normal beating, has been widely recognized for its high efficiency. However, the high cost, late market entry and lack of public awareness have resulted in the popularity of AEDs far from the ideal level. They are still hard to find in many public places, limiting the golden time window for first aid.
[0004] Although the importance of cardiopulmonary resuscitation is becoming increasingly prominent, the proportion of people who have received professional training and can master its skills is still low. In addition, training often focuses on imparting theoretical knowledge and lacks sufficient practical opportunities. Operations such as chest compressions cannot be performed on normal people, so even trained personnel may not be able to perform well in actual operations due to lack of skills.
[0005] Standard chest compressions require a certain amount of force to ensure the depth of compressions, but this requirement often makes witnesses worried that excessive force may cause additional damage to the patient, such as rib fractures. This psychological barrier, coupled with the difficulty in accurately controlling the force of compressions in actual operations, leads to many potentially effective compressions not being implemented, or insufficient force to achieve the expected first aid effect.
[0006] For some critical illnesses, such as cardiac arrest, the first few minutes are called the "golden four minutes", which is the key period for effective first aid and saving lives. However, even if the ambulance responds quickly, it is often difficult to arrive at the scene in such a short time, making self-rescue and mutual rescue during this period particularly important. Summary of the invention
[0007] The present invention is intended to provide an intelligent emergency procedure automation system to solve the technical problem that emergency operations cannot be effectively implemented in the prior art.
[0008] To achieve the above-mentioned object, the present invention adopts the following technical solutions: an intelligent emergency process automation system, including a cardiopulmonary resuscitation assistance module for assisting a witness to perform effective cardiopulmonary resuscitation on a patient, the cardiopulmonary resuscitation assistance module including a chest compression unit, a patient monitoring unit and an effectiveness correction unit;
[0009] A chest compression unit, including a compression pad, in which a pressure sensor and a displacement sensor are embedded, for collecting compression intensity and compression deformation in real time, and transmitting the collected data to the effectiveness correction unit;
[0010] Patient monitoring unit, including an electrocardiogram sensor for detecting cardiac electrical activity, detecting and recording the patient's cardiac electrical activity to provide a basis for evaluating the effectiveness of resuscitation;
[0011] The effectiveness correction unit has a preset chest compression evaluation model, which is used to receive and process data from the chest compression unit, evaluate the effectiveness of chest compression, provide chest compression guidance, and dynamically adjust the guidance content according to the monitored patient status information.
[0012] The principle and advantages of this solution are: through the pressure sensor and displacement sensor in the compression pad, the compression force and compression deformation of the witness during chest compression are collected in real time, that is, the depth of the compression pad sinking with the patient's chest; these data can accurately reflect the intensity and depth of the compression, which is a key indicator for evaluating the effectiveness of compression. The electrocardiogram sensor is used to detect and record the patient's cardiac electrical activity, providing an important basis for subsequent evaluation of the resuscitation effect; the electrocardiogram data can reflect the patient's heart state and help determine whether the resuscitation operation is effective. The effectiveness correction unit receives data from the chest compression unit and the patient monitoring unit, and analyzes it using a preset chest compression evaluation model. The model can evaluate the effectiveness of the compression, including whether the compression force is appropriate, whether the compression depth meets the standard, etc., and provide real-time visual or auditory compression guidance based on this. If the compression is insufficient or excessive, a red light and voice prompt will be given to guide the witness to adjust the compression force, frequency, etc.
[0013] It can significantly improve the effectiveness of cardiopulmonary resuscitation performed by witnesses and reduce ineffective compressions caused by lack of skills or psychological barriers; it can provide intuitive visual and auditory feedback to witnesses to guide them to perform standardized compression operations and reduce the risk of harm to patients due to improper operation; compared with automatic external defibrillators (AEDs), this solution has lower costs, simpler operation, and is easier to popularize and promote in public places such as communities, schools, and workplaces, thereby improving the public's awareness and ability of first aid.
[0014] Preferably, as an improvement, the cardiopulmonary resuscitation assistance module includes an artificial respiration unit, the artificial respiration unit includes a breathing mask for isolating the first aid personnel and the patient during the first aid process, an airflow sensor for real-time detection of airflow velocity and volume is provided in the airflow channel of the breathing mask, the artificial respiration unit converts the detected airflow velocity and volume data into the frequency and tidal volume of artificial respiration, and transmits the data to the effectiveness correction unit;
[0015] The effectiveness correction unit is preset with an artificial respiration evaluation model for receiving and processing data from the artificial respiration unit and the chest compression unit, evaluating the effectiveness of artificial respiration, providing artificial respiration guidance, and dynamically adjusting the guidance content according to the monitored patient status information.
[0016] The beneficial effects of this improvement are: by introducing the artificial respiration unit, it can support the operation and guidance of two basic first aid skills, chest compression and artificial respiration, at the same time, making the first aid process more comprehensive and in line with the standard cardiopulmonary resuscitation process; the artificial respiration evaluation model preset in the effectiveness correction unit can receive and process data from the artificial respiration unit, including the frequency and tidal volume of artificial respiration, and then combine the patient's chest rise and fall monitored by the displacement sensor to comprehensively evaluate the depth and frequency of artificial respiration.
[0017] For non-professional first aid personnel, it may be difficult to correctly master the frequency and tidal volume of artificial respiration. This solution automatically monitors and evaluates the effectiveness of their operations, thereby reducing the difficulty of operation and improving the success rate of first aid. Using breathing masks to isolate first aid personnel and patients can effectively reduce the risk of cross-infection. Breathing masks can also provide first aid personnel with a certain sense of psychological security, allowing them to focus more on first aid operations.
[0018] Preferably, as an improvement, the cardiopulmonary resuscitation assistance module includes an information storage unit, and the information storage unit is used to record the witness's first aid operation parameters, patient status information and first aid time.
[0019] The beneficial effect of this improvement is that the operating parameters of the witness during the first aid process, such as the strength, frequency, depth of chest compressions, and the frequency and tidal volume of artificial respiration, are comprehensively recorded through the information storage unit, while the patient's heart rate data and other status information, as well as the start and end time of the first aid, are recorded; these data provide doctors with a rich source of information, helping them to more accurately evaluate the effectiveness of resuscitation.
[0020] Preferably, as an improvement, the intelligent first aid process automation system also includes an emergency call and response module, which is used to receive emergency signals, automatically trigger the first aid process, send an emergency rescue request to the nearest first aid center, and maintain real-time communication with the first aid center and on-site rescue personnel.
[0021] The beneficial effects of this improvement are: the introduction of the emergency call and response module enables the system to quickly and automatically trigger the first aid process after receiving an emergency signal, without the need for witnesses to manually call the emergency number, thereby greatly shortening the response time; and real-time communication helps the emergency center to understand the on-site situation in a timely manner, guide on-site rescue personnel to carry out preliminary processing, and deploy more rescue resources as needed.
[0022] Preferably, as an improvement, the surface of the pressure pad is marked with a pressure point mark, and with the pressure point mark as the center, the pressure sensors and displacement sensors are distributed in the pressure pad in a layout manner from the center to the outside in a dense manner and gradually sparsely distributed.
[0023] The beneficial effects of this improvement are: this layout makes the sensor density near the pressing point higher and the sensitivity stronger, which can more accurately capture the changes in force and displacement during the pressing process, thereby more accurately evaluating the quality and effect of the pressing; as the distance from the pressing point increases, the sensor density gradually decreases, which not only reduces unnecessary costs but also avoids data redundancy.
[0024] Preferably, as an improvement, the effectiveness correction unit is also used to identify the witness' current first aid operation type based on the data collected by the artificial respiration unit and the chest compression unit, and guide the witness to switch the first aid operation type between artificial respiration and chest compression.
[0025] The beneficial effects of this improvement are: during cardiopulmonary resuscitation, artificial respiration and chest compression are two alternate emergency operations; the effectiveness correction unit automatically guides the witness to perform necessary operation switching, which can ensure the consistency and efficiency of the emergency operation; significantly reduce the risk of operational errors, and ensure that every operation is accurate;
[0026] Through the guidance and switching prompts of the effectiveness correction unit, witnesses can respond to first aid situations more calmly, reduce tension and anxiety, and it is also a recognition of correct operation, making witnesses more willing to lend a helping hand in an emergency.
[0027] Preferably, as an improvement, the effectiveness correction unit utilizes historical data and a machine learning algorithm to construct an artificial respiration assessment model and a chest compression assessment model to evaluate and guide the cardiopulmonary resuscitation operation of the witness.
[0028] The beneficial effects of this improvement are: through the artificial respiration and chest compression effects of a large number of patients, the relationship between ventilation volume and chest rise and fall height or the relationship between compression intensity and compression sinking depth is analyzed, whether the gas successfully enters the chest during artificial respiration is judged, and whether the frequency and air volume are within the standard range is calculated, and the optimal compression parameter range required by the patient is predicted.
[0029] Preferably, as an improvement, the information storage unit integrates GPS or similar location service technology to acquire and record the location information of the cardiopulmonary resuscitation assistance module in real time, and when an emergency is detected, sends the emergency status signal, device coordinate information and patient condition to the emergency call and response module.
[0030] The beneficial effect of this improvement is that in an emergency, this information can be quickly sent to the emergency call and response module, allowing the emergency center to immediately determine the location of the equipment and quickly dispatch the nearest rescue force to the scene, greatly shortening the response time.
[0031] Preferably, as an improvement, a one-way valve for preventing gas reflux is provided inside the breathing mask.
[0032] The beneficial effects of this improvement are: the design of the one-way valve can ensure the one-way flow of gas during breathing, preventing the patient's exhaled gas from flowing back into the breathing mask, thereby effectively preventing the risk of cross infection; the smooth opening and closing of the one-way valve can ensure the smooth flow of gas during breathing, reduce resistance, improve breathing efficiency, and simplify the operation process of artificial respiration.
[0033] Preferably, as an improvement, the pressure pad is a silicone or highly elastic sponge material pad that fits the patient's chest.
[0034] The beneficial effect of this improvement is that the silicone or high-elastic sponge material has good softness and elasticity, can better fit the contour and curve of the patient's chest, and reduce the monitoring error of the internal sensor. BRIEF DESCRIPTION OF THE DRAWINGS
[0035] Figure 1 This is a block diagram of the module composition of an embodiment of the present invention. DETAILED DESCRIPTION
[0036] The following is further described in detail through specific implementation methods:
[0037] Example
[0038] Basically as attached Figure 1 As shown, an intelligent first aid process automation system includes a cardiopulmonary resuscitation assistance module and an emergency call and response module.
[0039] The cardiopulmonary resuscitation assistance module is used to assist witnesses in performing effective cardiopulmonary resuscitation on patients, and monitor and record the patient's first aid data. The cardiopulmonary resuscitation assistance module includes: artificial respiration unit, chest compression unit, patient monitoring unit, effectiveness correction unit and information storage unit.
[0040] The artificial respiration unit includes a breathing mask, which is made of medical grade materials and is used to effectively isolate the first aid personnel and the patient during the first aid process, reduce the risk of cross infection, and also reduce the psychological burden of the first aid personnel during artificial respiration. A one-way valve is installed in the breathing mask to prevent the patient's exhaled gas from flowing back to the first aid personnel.
[0041] An airflow sensor is installed in the airflow channel of the breathing mask. The airflow sensor is used to detect the airflow velocity and volume in real time, and then convert it into the frequency and tidal volume of artificial respiration through the preset artificial respiration monitoring model. The artificial respiration unit transmits data such as the frequency and tidal volume of artificial respiration to the effectiveness correction unit. The data monitored in real time by the artificial respiration unit allows the subsequent effectiveness correction unit to evaluate the limitation of each breath and ensure that the gas enters the patient's lungs correctly to achieve sufficient ventilation.
[0042] The chest compression unit includes a compression pad, which is made of a soft and elastic material, such as silicone or high-elasticity sponge, so that it can fit the patient's chest and deform during the compression process. A pressure sensor and a displacement sensor are embedded inside the compression pad to reflect the degree of chest compression. The pressure sensor is used to collect the compression intensity value, and the displacement sensor is used to collect the compression deformation of the compression pad when it is compressed, that is, the depth of the compression pad sinking. The chest compression unit collects the compression intensity value and the compression deformation in real time, and transmits the collected data to the effectiveness correction unit. The chest compression unit feeds back the collected data to the effectiveness correction unit in real time for subsequent analysis of the compression intensity, depth and frequency, to ensure that the compression is both effective and avoids excessive injury.
[0043] The surface of the pressing pad is marked with pressing point marks. The emergency personnel will lay the pressing pad on the front of the patient and align the pressing point with the junction of the middle and lower third of the sternum, that is, the junction of the line connecting the bilateral nipples and the sternum. With the pressing point as the center, the pressure sensors and displacement sensors are distributed in the pressing pad in a layout manner from densely distributed in the center to gradually sparsely distributed outwards, so that a key area located in the lower half of the patient's sternum and a non-key area located at the edge of the pressing pad are formed on the pressing pad.
[0044] The patient monitoring unit includes sensors for detecting and recording cardiac electrical activity, providing a basis for subsequent evaluation of resuscitation effectiveness. The ECG sensor is a plurality of measuring electrodes, each of which is used to be placed at a specific position of the patient, such as the chest (V1-V6 position) and the arm (RA, LA, RL, LL position). You can select a few of the settings, or you can use the standard 12-lead ECG setting.
[0045] The patient monitoring unit uses measuring electrodes to detect the weak electrical signals generated by the heart, increases the signal emphasis through an amplifier, and finally removes noise and interference through filtering, converting the processed signal into digital data and transmitting it to the validity correction unit.
[0046] The effectiveness correction unit is used to judge the effectiveness of artificial respiration and chest compression, and provide guidance to witnesses on the correct cardiopulmonary resuscitation operation. The effectiveness correction unit is preset with an artificial respiration assessment model and a chest compression assessment model, which are built based on historical data and machine learning algorithms. The machine learning algorithm can be a decision tree, random forest, neural network, etc.
[0047] The effectiveness correction unit receives data transmitted from the artificial respiration unit and the chest compression unit, and inputs the frequency and tidal volume of artificial respiration and the compression deformation detected by the displacement sensor of the chest compression unit, i.e., chest rise and fall, into the artificial respiration evaluation model. It uses historical data, including the artificial respiration effects of different patients, such as the relationship between the ventilation volume and chest rise and fall height of different patients, to analyze and determine whether the gas successfully enters the chest during artificial respiration, and calculates whether the frequency and air flow rate are within the standard range. If they are met, a green light will be displayed, and if not, a red light will be displayed with a voice prompt to guide witnesses to change the frequency, adjust the air flow, or if the current artificial respiration is invalid.
[0048] The validity correction unit is also used to identify the witness's current first aid operation type based on the data collected by the artificial respiration unit and the chest compression unit, and guide the witness to switch between artificial respiration and chest compression operations to achieve standardized alternating operations. For example, after 30 chest compressions, the voice prompts the witness to perform artificial respiration twice, and then repeats the operation instructions according to the preset first aid steps.
[0049] The chest compression assessment model is fed with compression force and compression deformation values, and historical data, including compression effects of patients with different conditions, such as compression force and compression sinking depth of different patients, are used to predict the optimal compression parameter range required by the patient. Based on the real-time feedback of the compression effect, that is, the patient's heartbeat monitored by the patient monitoring unit and the current compression level detected, it is detected whether the current chest compression meets the optimal compression range. If it meets the range, a green light prompts, if not, a red light and voice prompts, and dynamically prompts witnesses to adjust the compression parameter suggestions, such as the strength and frequency of compressions; to ensure effective compression while avoiding excessive compression injuries.
[0050] The information storage unit is used to record the first aid operation parameters of the witnesses, the patient's status information, the first aid time and other information. The first aid time is recorded to help the doctor evaluate the effect of the resuscitation after the patient is sent to the hospital. By recording the resuscitation time, the doctor can understand the urgency and efficiency of the resuscitation process, and thus evaluate whether the resuscitation measures are timely and effective.
[0051] The information storage unit also integrates GPS or similar location service technology to obtain and record the current location information of the cardiopulmonary resuscitation assistance module in real time, such as latitude, longitude, altitude, etc. When the cardiopulmonary resuscitation assistance module detects an emergency situation such as apnea or cardiac arrest in the patient through the patient monitoring unit, the information storage unit will immediately send the emergency status signal, the current device coordinate information and the patient's condition to the emergency call and response module.
[0052] The emergency call and response module is used to receive emergency signals and automatically trigger the emergency process, including sending an emergency rescue request to the nearest emergency center through data communication, including key information such as the patient's condition, current location, and estimated arrival time. The emergency center will quickly dispatch the nearest emergency vehicle and medical staff to the scene based on the information received. During the entire emergency process, the emergency call and response module will maintain real-time communication with the emergency center and on-site rescue personnel to ensure unimpeded information flow and provide necessary support and guidance for the rescue operation.
[0053] After an AED completes a defibrillation, it usually takes a while to assess whether the patient needs another defibrillation. Compared to an AED, the CPR assistance module helps reduce unnecessary interruptions during CPR by detecting and guiding witnesses to perform standardized CPR, motivating witnesses to continue positive operations, thereby maintaining the stability of the patient's blood circulation and oxygen supply. In addition, the AED is relatively expensive, while the CPR assistance module is relatively low-cost and easy to operate, which is conducive to popularization and promotion on a wider range, and is more likely to be equipped in communities, schools, workplaces and other places, thereby increasing the survival rate of patients in emergency situations.
[0054] In actual use, when a witness finds that a patient is in an emergency such as respiratory arrest or cardiac arrest, he or she will immediately find a nearby cardiopulmonary resuscitation assistance module and start it. The witness will place the measuring electrode stickers on the patient's specific position according to the markings on the measuring electrodes to monitor the heart's electrical activity.
[0055] The compression pad of the chest compression unit is laid on the front of the patient, ensuring that the compression point is aligned with the junction of the middle and lower thirds of the sternum. The witness first performs chest compressions on the compression pad according to the instructions. The pressure sensor and displacement sensor in the compression pad collect the compression intensity value and compression deformation in real time and transmit them to the effectiveness correction unit.
[0056] The effectiveness correction unit receives data from the artificial respiration unit and the chest compression unit, and analyzes it using the preset chest compression evaluation model. If the compression force and depth meet the optimal range, a green light will be displayed; if not, a red light will be displayed and a voice prompt will be given to the witness to adjust the compression parameters.
[0057] When the number of effective compressions reaches one round, the effectiveness correction unit will voice prompt the witness to switch to artificial respiration, and then the artificial respiration assessment model will analyze it. If the frequency and tidal volume meet the standard range, the green light will be prompted; if not, the red light will be turned on and the voice prompts the witness to adjust. The witness will be guided to perform the 30:2 alternating operation.
[0058] When the cardiopulmonary resuscitation assistance module detects that the patient has sustained respiratory apnea or cardiac arrest, the information storage unit sends the emergency status signal, current device coordinate information and patient status to the emergency call and response module. After receiving the emergency signal, the emergency call and response module automatically sends an emergency rescue request to the nearest emergency center through data communication, including the patient's condition, current location and estimated arrival time. Based on the received information, the emergency center quickly dispatches the nearest emergency vehicle and medical staff to the scene. During the entire emergency process, the emergency call and response module maintains real-time communication with the emergency center and on-site rescue personnel to ensure unimpeded information flow. After the emergency personnel arrive at the scene, they take over the cardiopulmonary resuscitation operation and send the patient to the hospital for further treatment. All emergency operation parameters, patient status information, emergency time and other information recorded by the information storage unit provide important basis for subsequent medical evaluation and resuscitation effect analysis.
[0059] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
