Technical Field

The invention belongs to the field of public emergency equipment, and particularly relates to a public emergency system and an implementation method.

Background

For the sudden cardiac arrest in public places, a great number of cases exist every year, if timely and scientific treatment is lacked, the life characteristics of a patient can be lost quickly, irretrievable consequences are caused, the optimal treatment time is within eight minutes of the sudden cardiac arrest, and professional rescuers are too late, so that the patient needs to be treated before an ambulance comes. In the face of cardiac arrest, the patient needs to be rescued by chest compressions, but the wrong way of compression may adversely affect the patient, so in public places, effective and scientific chest compressions are necessary before the ambulance arrives.

The following points need to be considered when performing chest compressions: the position to be pressed is accurate (1/3 in the middle and lower sternum), the depth to be pressed is accurate (the depth is 5-6 cm), the frequency to be pressed is accurate (the frequency to be pressed is 80-100 times/min, the frequency to be used for children is 90-100 times/min, the ratio of the time of pressing to the time of relaxation is proper to be 1: 2), the posture of the patient is accurate (the body of the patient lies flat, the head of the patient is properly lowered, the content is prevented from flowing back into the trachea when the patient presses), and the posture to be pressed is accurate (the palm root of the rescuer is tightly attached to the pressed part of the chest, the other palm of the rescuer is placed on the back of the hand, the two hands are overlapped in parallel, the fingers are. Based on the above compression points, non-professional compression is unreliable, and experiments show that using an external chest compression machine for treatment would be a better choice for better treatment. However, in the face of sudden cardiac arrest in public places, the use of a cardiopulmonary resuscitator is obviously inappropriate for the following reasons: the cardiopulmonary resuscitator alone cannot observe various vital signs of a rescued person in real time, and improper use of the cardiopulmonary resuscitator can cause negative effects on a patient. The same effect can not be generated under the condition of pressing different patients, and the pressing efficiency can be greatly reduced if the physical signs of the patients cannot be monitored in real time. It would be very helpful if a cardiopulmonary resuscitation machine and other devices for monitoring vital signs could be stored in a public place, but this is not practical because many devices are not universally available, if not a professional, to complete the treatment within eight minutes of the patient's cardiac arrest.

In view of the above situations, there is a need to develop a public first aid product, which is placed in public places, has the characteristics of convenience, practicability, accurate compression, real-time monitoring, real-time feedback and real-time adjustment, and enables patients to obtain scientific and accurate chest compression therapy within eight minutes of sudden cardiac arrest.

s1, taking out the public emergency system;

s2, the rescuer holds the patient flat, wears a bracelet on the patient, and wears AR glasses and chest pressing gloves;

s3, performing chest compression by the rescuer according to the heart position of the patient, monitoring the compression data by an acceleration sensor on a chest compression glove, transmitting the compression data to AR glasses through a Bluetooth module, and giving feedback information to the rescuer;

In step S3, the rescuer scans the body contour of the patient by means of the AR glasses, and analyzes the heart position of the patient based on the cloud data AI algorithm.

Compared with the prior art, the invention has the following technical effects:

1. in the prior art, a pressure sensor is used for correcting the posture of a rescuer, but the muscle density of each person is different by combining with the actual rescue environment and regulations, the corresponding pressing depth of the same pressure applied to different persons is different, and the pressure sensor can generate larger errors in displacement judgment. The invention adopts the acceleration sensor to calculate and output the pressing depth and frequency in an integral way, and feeds back the data of the pressing depth and frequency to the rescuer in real time, so that the rescuer can adjust the action of the rescuer in time, and the invention has the advantage of ensuring the effective rescuing operation in real time.

2. The location of the compressions according to the relevant prescription CPR is the mid-lower sternum 1/3, the mid-point between the two papillary lines, or the two lateral fingers on the xiphoid process, which is difficult for non-professionals to judge. The existing technology for judging the pressing position is to place the rescued person on a fixed human-shaped carpet, and inform the heart position of the rescued person about the appointed human-shaped contour on the carpet; because the difference of the height of each person brings the difference of the heart of each person, namely the pressing position, the fixed contour can produce larger error when judging the pressing position. The invention adopts the technical means of scanning the contour of the human body to calculate the heart (pressing) position, and has the advantage that non-professionals can carry out rescue rapidly.

3. The invention feeds back the operation of the rescuer and the vital signs of the rescued person in a data visualization mode, and has the advantage of higher efficiency of the whole operation process. The displacement frequency data collected and calculated on the gloves and the heart rate data collected on the heart rate bracelet can form an intuitive chart in real time and be displayed on the glasses. Compared with the existing indicator lamp feedback, the visual pattern and the striking color of the chart enable the rescuers to realize whether the operation is correct or not and monitor the life state of the rescuers in real time, and the efficiency of the whole rescue process is improved.

4. The acceleration zero calibration technology is adopted, zero calibration is carried out once each time half-stroke pressing is completed, all data become 0, the displacement error obtained through acceleration integration is smaller, the data are more accurate, and the method has the advantage of smaller error.

5. According to the invention, the emergency actions are packed and civilized, so that a complete pre-hospital emergency service system is formed, the life of public places is more perfectly guaranteed, and the pre-hospital emergency efficiency is improved. The complete pre-hospital emergency service system comprises a complete system of suppliers, technical support, users, products and service flows.
