A kind of external chest compression device for CPRTechnical field
The present invention relates to a kind of press device, specifically a kind of external chest compression device for CPR.
Background technique
CPR is the rescue key measure that the acute disease urgent patient stopped for respiratory heart stop jumping is taken, i.e., presses outside chestSwaging replaces autonomous respiration at the temporary autonomous beating for manually recycling and restoring, using artificial respiration.Carotid pulsation is observed,Primary beating can be contacted after pressing every time when effectively.Stop if beating after stopping pressing, shows to continue to press.Such as stopIt beats and exists after only pressing, illustrate that the autonomous heartbeat of patient has restored, closed cardiac massage can be stopped.
The purpose of CPR is open airway, rebuilds breathing and circulation.CPR is firstly the need of holding patient respirationRoad it is unobstructed, with Simple artificial respirator or life-kiss, observing thorax, whether there is or not rhythm protuberances to judge to ventilateValidity, in joint cardiac compression when only one first aid person to patient carry out cardiopulmonary resuscitation when, should often do 30 timesChest cardiac compression, alternately 2 artificial respirations.
When carrying out CPR to patient, the prior art carries out external chest compression to patient using medical staff and helps patientRestore pulse, the mode manually pressed needs well-trained medical staff to carry out, for the general public that do not undergo training, the heartLung resuscitation effect is poor, it is difficult to effectively be rescued to patient；At the same time, it needs to cooperate while external chest compression artificialBreathing, the prior art needs medical staff to practice artificial respiration while pressing, and not only operation difficulty is larger, and effect compared withDifference.
