Cardio-pulmonary resuscitation device at abdomen

Abstract

The invention discloses a cardio-pulmonary resuscitation device at the abdomen, consisting of three parts of a pressing plate, a negative pressure device and a pressing handle; the shape of the pressing plate is polygon, the upper part of which is an isoceles triangle and the lower part of which is a rectangle; the long edge of the rectangle is the bottom edge of the isoceles triangle; the central part of the rectangle is a round opening; the negative pressure device is a piston type negative pressure device and an opening thereof is the round opening of the rectangle of the lower part of the pressing plate and is closely connected with the round opening; and the pressing handle is positioned at the upper part of the negative pressure device and is closely connected with the shell of the negative pressure device at the horizontal plane parallel to the pressing plate. The cardio-pulmonary resuscitation device leads the blood in the organs in abdominal cavity accounting for 25 percent of the whole blood to backflow to the heart, thus effectively improving coronary perfusion; the pressing and lifting to the abdomen can lead a diaphragm to raise and lower greatly; therefore, in the process of each pressing, the cardio-pulmonary resuscitation device can lead the rescued person to inhale and exhale, does not need mouth-to-mouth artificial respiration and does not need two persons to rescue.

Description

technical field [0001] The invention relates to a medical device for first aid, in particular to an abdominal cardiopulmonary resuscitation device. Background technique [0002] The general cardiopulmonary resuscitation method for rescuing patients with cardiopulmonary arrest is chest compressions with bare hands or using a device, accompanied by mouth-to-mouth artificial respiration, but the success rate is only 5% to 10%, depending on how much the rescuer's reaction time is Quick, how good is technology. [0003] Traditional cardiopulmonary resuscitation not only has a low success rate, but also easily causes rib fractures of the rescued. About 1 / 3 of the rescued ribs are fractured. [0004] Mouth-to-mouth artificial respiration of traditional CPR may increase the risk of disease transmission, thus becoming a factor hindering the implementation of CPR. In a study of 433 physicians and 152 nurses, 45% of physicians and 80% of nurses said they would refuse to perform mouth...
