Description

Portable CPR auxiliary device

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to a portable CPR auxiliary device.

Background

CPR (cardiopulmonary resuscitation) is a necessary technique in the field of emergency medical services, and life and death of rescuees (patients) depends on the appropriateness of the technique. When CPR is to be performed, the rescuer compresses the sternum on the upper side of the chest. The compression replaces the patient's heart and can cause oxygenated blood to circulate throughout the living body. As an index of chest compression, it is considered effective to apply compression with an offset amount of 5cm or more.

Studies have shown that the survival prospects of patients can be improved by the administration of high quality CPR. The quality of CPR is directly related to the quality of chest compressions, some of which are determined by: the compression depth, rate and whether each compression is fully released during the upstroke. Good chest compressions are generally such that at a rate of about 100 compressions per minute, an adult compression depth of at least five centimeters, a child compression depth greater than 1/3 chest anteroposterior diameters, and both adult and child should ensure complete thoracic rebound.

Since CPR is related to the life and death of the victim, devices have been developed that are placed between the chest of the victim and the rescuer's hands to assist in chest compressions. In each device, it is detected whether the proper force is applied to the sternum at the proper time intervals, and depending on the detection result, the rescuer is given an appropriate notice (such as "insufficient force" or "too late compression time").

The CPR auxiliary device in the prior art needs to be prevented from being positioned above the chest of a rescued person as a whole when in use, has no independent compression area, and is easy to displace and cause compression dislocation when in use.

The utility model has two working modes:

the first method comprises the following steps: the first aid is used for:

when the device is used, 1, the magic tape embedded with the sensor is taken down from the winding post, the electrode slice is inserted into the electrode slice interface behind the device, the back of the device is pasted on the chest of a patient, a heart rhythm analysis result is waited, meanwhile, the fingers of the patient are placed on the heart rate blood oxygen sensor for auxiliary judgment, and the detection before CPR (cardio-pulmonary resuscitation) is carried out;

2. whether the patient is a shockable rhythm/whether the patient is asystole;

3. if a shockable rhythm (ventricular fibrillation) the display device prompts the need for an AED (automatic external defibrillator), whether to call a drone or emergency ambulance, then to enter a CPR (cardiopulmonary resuscitation) procedure/to enter a CPR (cardiopulmonary resuscitation) procedure if cardiac arrest;

upon entering CPR (cardiopulmonary resuscitation):

1. screen playing a CPR (cardiopulmonary resuscitation) tutorial;

2. the buzzer buzzes at a beat of 100-120 times/minute, and the indicator light flickers blue light at a secondary frequency;

3. the magic tape embedded with the sensor is placed at the midpoint of the two breast connecting lines of a patient, a rescuer covers the hand on the sensor of the magic tape to press the chest, and the sensor can automatically calculate the pressing frequency. When a user presses down to a standard depth range, the sensor transmits an electric signal to the first centralized control mainboard, the first centralized control mainboard sends an instruction to enable the somatosensory interaction device to vibrate, and the user is prompted to stop pressing in a vibration mode;

4. the pressing times reach 30 times;
