Detailed description of the invention
Seeing Fig. 1, a kind of lightweight separate mechanical external chest compression device, it includes FREQUENCY CONTROL valve 1, described frequency control
Valve 1 processed is connected with source of the gas, and supplies according to first aid compression frequency to drive press head 4 to press thoracic cavity, described frequency control
Valve 1 processed is connected to the air inlet of pneumatic press section 3 by tracheae 2, and the end that ejects of described pneumatic press section 3 is provided with for pressing
The press head 4 in thoracic cavity, described pneumatic press section 3 is provided with the hanger 6 coordinating with bandage 5, and described bandage 5 passes through hanger 6 will
Described pneumatic press section 3 be bundled in chest sentence carry out chest compression promote CPR.This mechanical type external chest compression fills
Put employing split-type structural design, control part is separated with pressing part (need to act on the part of human body), reduces support
The weight of the pressing component on human body, reduce pressing be detained (one of the key factor being to weigh pressing quality is detained in pressing,
During pressing release, if release is not exclusively, can cause the thorax can not resilience completely) and then alleviate bearing of thoracic cavity resilience
Carry, may advantageously facilitate CPR, and the small volume, easy to operate of pressing part, each parts are less, easily assemble, and add
