Description

Cardiopulmonary resuscitation auxiliary device

[technical field]

The utility model relates to the field of medical instrument technology, in particular to a kind of cardiopulmonary resuscitation auxiliary device.

[background technique]

Since human body is when by heart disease, hypertension, traffic accident or the acute illness such as drowned or unexpected injury, may cause Shock generates the phenomenon that breathing stops suddenly with heartbeat, and brain cell and organ-tissue are often because enough blood can not be obtained at this time Anoxic is caused with oxygen supply.In order to avoid the generation of anaerobic condition, before and after patient is sent to hospital, it is necessary to routinely into Row cardiopulmonary resuscitation (CPR) breathes come the blood oxygen concentration for maintaining patient and heartbeat.The cardiopulmonary resuscitation (CPR) of the prior art and its Used cardiopulmonary resuscitation auxiliary device generallys use the recovery mode of single pressing chest.During evolution due to the mankind It is therefore, either upright or lie down but also double lower limb becomes hypertrophy while gradually liberating double upper limbs, under the mankind are double Limb has a large amount of blood to be distributed.For sudden arrest of heart beat (CA) patient, a large amount of blood products are in double lower limb.Using single chest Outer pressing mode is acted in spite of chest pump or heart pump mechanisms play, but circulating blood volume is extremely limited, and blood circulation speed is slow Slowly, returned blood volume is few, and therefore, CPR success rate is very low.In order to improve Success rate, people grind cardiopulmonary resuscitation Study carefully and improves.Wherein, it is special according to CPR principle and human body itself dissection that double lower limb buckling, which squeezes cardiopulmonary resuscitation (CPR-BPLE), Point is to a kind of novel resuscitation technique obtained after cardiopulmonary resuscitation improvement.

When double lower limb buckling squeezes cardiopulmonary resuscitation operation, patient is lieed down, and a rescuer is located at patient body side, is implemented External chest compression；Another rescuer is located at patient body foot end, gets down on both kneels on ground or hospital bed, leans forward above the waist, and both arms stretch, Both hands are placed in patient's both legs middle position, and patient's both legs are intersected, and double lower limb is from hip joint, knee sprung and to lower abdomen Portion direction firmly squeezes.This kind of cardiopulmonary resuscitation is squeezed using external chest compression joint double lower limb buckling, chest pump and/or heart pump mechanism It plays a role, not only the vein blood back amount of double lower limb siltation increases, circulation rate is accelerated, and the arterial system of double lower limb is in outer masterpiece It also changes under, increases total peripheral resistance, returned blood volume is caused to increase, arterial pressure increases.On the other hand, double lower limb After blood vessel receives continuous extrusion, the total path of systemic blood circulation shortens, and whole body blood volume divides again in each position, each organ Match.Pelvic cavity and underbelly pressure increase simultaneously, and returned blood volume further increases.These factor collective effects, it is ensured that the heart, The vitals such as brain, kidney preferentially obtain hemoperfusion, are conducive to improve CPR success rate.However, this kind of cardiopulmonary resuscitation needs simultaneously Two rescuer's compounding practices are wanted, a large amount of manpower need to be spent, waste the human resources of hospital.
