Judging method of external chest compression strength and full-automatic external defibrillator with compression energy calculation and rapid charging function

Abstract

The invention relates to a judging method of an external chest compression strength and a full-automatic external defibrillator with compression energy calculation and rapid charging function. The judging method comprises the following steps of: setting a compression depth paste for acquiring compression pressure signals and compression depth signals, placing the compression depth paste in a compression position and compressing the compression depth paste; transmitting a compression pressure to a patient by using the compression depth paste; and calculating compression energy according to the pressure signals and the compression depth signals and then judging whether the compression strength is suitable or not according to the compression energy. The defibrillator comprises a main machine and the compression depth paste, wherein a central control circuit is installed in the main machine, and the compression depth paste is provided with a compression depth detecting module and a pressure detecting module. With the judging method, the external chest compression strength is better judged by using the compression energy as an index so that the judgment is more accurate, and the adaptation is stronger; and the defibrillator has the function of compression energy calculation and display, can effectively control the compression strength and can be effectively and rapidly charged.

Description

technical field [0001] The invention relates to a method for judging the intensity of external chest compressions, and also relates to a fully automatic external defibrillator with compression energy calculation and fast charging using the method, which belongs to the field of medical technology. Background technique [0002] Automatic external defibrillator, as an important first aid equipment, plays an irreplaceable role in the emergency rescue process of cardiac patients, in which biphasic waves with low energy, high success rate and low myocardial damage characteristics are fully automatic external defibrillators The defibrillator is another important development trend after the traditional one-way wave automatic defibrillator. The two-way wave automatic external defibrillator can not only identify ventricular fibrillation in time, but also has a high defibrillation success rate and significantly reduces the damage to myocardial function. The body and nervous system func...

However, there is currently no defibrillator that calculates the energy of chest compressions. Because different doctors apply different forces and compression depths to patients, it may cause different degrees of impact on the patient's lungs. Therefore, there is a method for calculating the compression energy. AED plays an important role in guiding physicians to press

[0004] In order to quantitatively judge the strength of compression, people have proposed a method to use the detection of compression depth as a judgment index. However, due to the large changes in the body shape, fat and thinness of different patients, the appropriate compression depth for some patients is not suitable for other patients. Not suitable, so the range of adaptation of this indicator is limited
