Description

Cardiopulmonary resuscitation auxiliary device

Technical Field

The utility model belongs to the technical field of cardiopulmonary resuscitation auxiliary assembly, concretely relates to cardiopulmonary resuscitation auxiliary device.

Background

Cardiopulmonary resuscitation refers to a phenomenon that when a human body suffers from external or self basic injury, shock occurs to generate sudden stop of respiration and heartbeat, in order to avoid emergency rescue measures taken when brain cells and organ tissues cannot obtain enough blood and oxygen and irreversible injury occurs due to respiration and heartbeat stop, cardiopulmonary resuscitation successfully treats tens of thousands of patients suffering from cardiac arrest every year from clinical application, but in the face of huge patients suffering from cardiac arrest, the resuscitation success rate is still low, and because human beings gradually liberate two upper limbs and simultaneously cause the two lower limbs to become abnormally developed in the evolution process, both lower limbs of the human beings have a large amount of blood distribution, a large amount of blood is accumulated in both lower limbs after the patients suffer from cardiac arrest, when the traditional cardiopulmonary resuscitation is adopted, a chest pump or a heart pump mechanism plays a role, but the blood circulation is very limited, the blood circulation speed is slow, and the blood volume of the heart is small, so the successful rescue rate is very low.

Therefore, in order to improve the resuscitation success rate and the survival rate of discharge from hospital, people research and improve standard cardiopulmonary resuscitation (S-CPR for short), wherein the double-lower-limb buckling-pressing cardiopulmonary resuscitation (CPR-BPLE) is a novel resuscitation technology which is obtained by improvement according to the traditional cardiopulmonary resuscitation principle and the self anatomical characteristics of a human body, when the double-lower-limb buckling-pressing cardiopulmonary resuscitation is adopted, a patient lies flat, and a rescuer is positioned at one side of the body of the patient to perform chest compression; the other rescuer is positioned at the foot end of the body of the patient, knees of the patient are kneeled on the ground or a sickbed, the upper half of the body is forward inclined, two arms of the patient are straightened, two hands of the patient are placed at the middle position of the two shanks of the patient, the two shanks of the patient are crossed, the two lower limbs are bent from hip joints and knee joints and are forcibly pressed towards the lower abdomen, the cardiopulmonary resuscitation adopts chest pressing and combined bending pressing of the two lower limbs, not only the venous return blood volume of the two lower limbs is increased and the circulation speed is accelerated, but also the arterial system of the two lower limbs is changed under the action of external force, so that the total peripheral resistance is increased, the return blood volume is increased, the arterial blood pressure is increased, on the other hand, after the blood vessels of the two lower limbs are continuously pressed, the total path of the whole blood circulation is shortened, the whole blood volume is redistributed at each position and each organ, the, the method can ensure that important organs such as heart, brain, kidney and the like are preferentially perfused with blood, is favorable for improving the CPR success rate, and can greatly improve the treatment success rate of a patient, but needs two persons to cooperate and operate simultaneously, thereby limiting the treatment operation of the other person, and reducing the manpower resources which can be allocated when the patient is treated.
