Description

Cardiopulmonary resuscitation device with adjustable emergency clinic is clinical

Technical Field

The invention relates to the technical field of medical equipment, in particular to an emergency clinic adjustable cardio-pulmonary resuscitation device.

Background

Sudden Cardiac Arrest (SCA) outside hospitals is a major cause of death in the world. Chest compressions during cardiopulmonary resuscitation (CPR) remain one of the few proven treatments for patients with sudden cardiac arrest, supplying blood to critical organs (brain and heart-muscles) until spontaneous circulation recovery is desired. According to the european guidelines for cardiopulmonary resuscitation, fast and deep chest compressions, the use of Automated External Defibrillators (AEDs) and lowering body temperature as much as possible to 32 to 34 degrees celsius are the three major measures strongly recommended by the new edition of guidelines.

Experts have agreed on the importance of defibrillation early after sudden cardiac arrest, and the existing guidelines recommend that emergency personnel should perform CPR immediately and use a defibrillator as early as possible when an out-of-hospital sudden cardiac arrest event is witnessed or an in-hospital sudden cardiac arrest event occurs, but in the prior art, when the emergency personnel arrive at a patient site, mechanical chest compression devices and defibrillators need to be worn separately, and wearing the compression devices often needs to move or lift the patient, which easily delays rescue time;

there are studies that have shown that the compression profile (the rate at which the chest is compressed and decompressed), the frequency, depth and duty cycle of chest compressions can affect the blood flow and pressure achieved during CPR, and that defibrillation in concert can increase defibrillation success and survival, but existing compression devices and defibrillators require separate adjustments and are cumbersome to use.

Numerous studies indicate that hypothermia treatment has multiple protective effects, can simultaneously act on multiple targets of cerebral ischemia cascade injury reaction, and the main protective mechanisms of hypothermia treatment comprise lipid membrane fluidity maintaining, destructive enzyme reaction inhibiting, oxygen demand reduction in cerebral hypoperfusion area during reperfusion, lipid peroxidation inhibiting, cerebral edema alleviating, intracellular acidosis and the like. Research shows that low-temperature treatment can reduce neuronal apoptosis after cerebral ischemia, relieve white matter damage and inhibit astrocyte proliferation. It is reported that cryotherapy should be performed as early as possible after the ischemic injury, and the later the onset, the worse the therapeutic effect. The existing low-temperature treatment means can be well carried out only by transferring a patient to a hospital bed, and timely and effective low-temperature treatment on site is not easy to carry out.

Therefore, there is a need to provide an emergency clinic adjustable cardiopulmonary resuscitation device to solve the above problems in the background art.
