Description

A cardiopulmonary resuscitation device adapted to different groups of people

technical field

The invention relates to the technical field of medical devices, in particular to a cardiopulmonary resuscitation device adapted to different groups of people.

Background technique

Cardiopulmonary resuscitation Once cardiac arrest occurs, if immediate rescue and resuscitation is not obtained, it will cause irreversible damage to the patient's brain and other vital organs and tissues in 4 to 6 minutes. Therefore, cardiopulmonary resuscitation after cardiac arrest (cardiopulmonaryresuscitation, CPR) must be performed immediately on the spot. When doing cardiopulmonary resuscitation, the compression frequency needs to reach 100-120 times per minute, and the depth is 5-6cm. These feedbacks can be evidence-based when used on simulators.

However, when the medical staff rescues real people, they need to ensure that the compression frequency reaches 100-120 times per minute, and the compression depth is 5-6cm at the same time. The frequency is good for timing, but the depth is more difficult. It can’t be too shallow, there is no effect, and too deep, for fear of crushing the fracture of the patient. The medical requirement is a depth of 5-6cm. Therefore, we propose a more practical cardiopulmonary resuscitation device that is suitable for different groups of people.
