Description

Technical Field

[0001] The utility model relates to a medical appliance, in particular to a cardiopulmonary resuscitation auxiliary pressing pad. Background Art

[0002] The currently recognized standard for CPR is 120 compressions per minute and a chest compression depth of 5-6 cm. If the frequency and depth of compressions do not meet the above standards, it may result in inefficient or even ineffective compressions.

[0003] In order to ensure that the actions of emergency personnel during CPR are standardized and effective, they can only be trained on a regular basis, and the only training method is to simulate the operation on a mannequin, and the standardization and effectiveness of the actions will be judged by the personnel nearby or the testing agency inside the mannequin. However, at the actual CPR rescue site, emergency personnel can only rely on their usual training instincts to operate, without an effective feedback mechanism. At the same time, since the characteristics of the mannequin are definitely very different from those of real people of various body shapes, first aid only relies on the techniques and strength of daily training to operate, which is likely to affect the success rate of CPR and even cause potential risks.
