Description

Cardiopulmonary resuscitation device that can be customized to the patient's body shape

The present invention relates to a CPR device customizable to the body shape of a patient, and more particularly, to a CPR device customizable to the body shape of a patient capable of adjusting the height of a chest compression unit to suit the body shape of a patient.

Sudden cardiac death is on the rise due to the increase in cardiovascular diseases and the aging population. The rapid progress of Korea into an aging society means that a large number of the population may be exposed to the risk of sudden cardiac death. Therefore, interest in cardiopulmonary resuscitation (CPR), an emergency rescue activity in case of sudden cardiac arrest, is greatly increased.

On the other hand, in the case of cardiac arrest, emergency measures are required within 6 minutes, and in general, most of the witnesses who witness cardiac arrest patients outside the hospital are non-medical personnel. We are providing a lot of support for the activation of

Cardiopulmonary Resuscitation (CPR) is a technique in which a series of processes such as chest compressions, airway maintenance, and artificial respiration are repeated. After requesting help from the surroundings and reporting to the emergency rescue center, interlock both hands and press the center of the chest with the elbows with the elbows and press 30 times, at a depth of 4 to 6 cm. After chest compressions, secure an airway While checking whether the chest is inflated, perform artificial respiration for a total of 2 times, 1 time/1 second, and perform chest compressions and artificial respiration 2 times alternately.

However, even if the general public has received CPR training, there are problems in avoiding CPR due to the unfamiliarity of CPR and the burden of rib damage when a cardiac arrest patient occurs.

Accordingly, a cardiopulmonary resuscitation device that is attached to the chest of a cardiac arrest patient and performs cardiopulmonary resuscitation in an electronically controlled manner has been developed and used. The CPR device compresses the patient's chest after lowering the chest compression unit constituting the chest compression unit to the patient's chest in a state in which the chest compression unit for compressing the patient's chest is fixed to a pair of leg portions.

However, since each patient's body shape is different and the descending distance for descending the chest compression unit is limited, it is necessary to adjust the height of the chest compression unit itself according to the patient's body shape.
