Problems solved by technology

Its disadvantages are: the gas cylinder is relatively heavy, and it is extremely inconvenient to transport it as an accessory during the first aid process. The length of first aid time is limited by the volume of the gas cylinder, and it is difficult to realize light weight and portable operation.
[0005] Electric cardiopulmonary resuscitation devices, whose power mainly comes from rechargeable batteries, generally use worm gear transmission or a more complicated linkage mechanism to achieve reciprocating compression. Cardiopulmonary resuscitation devices using this method generally have a complex overall structure, bulky equipment, and are inconvenient to carry. , and the transmission efficiency is low, the battery power loss is serious, the battery life is short, and the equipment cost is high

Abstract

The invention discloses a mechanical type external chest compression device. The device comprises an outer barrel, a driving device is arranged inside the outer barrel, the lower end of the driving device is fixed to the bottom of the outer barrel through connecting pieces which are arranged in the radial direction, the upper end of an output shaft of the driving device is connected with a revolving shaft, two driving protrusions are arranged on the outer side face of the revolving shaft in the circumferential direction, and the upper end of the outer barrel is connected with a top cover; a cam jacking rod is arranged between the driving device and the outer barrel, the upper end face of the cam jacking rod is a concave-convex curved surface, long-strip holes are formed in the side wall of the cam jacking rod, the connecting pieces are placed in the long-strip holes so that the connecting pieces can be adapted to the axial motion of the cam jacking rod, a return spring is arranged in an inner chamber of the cam jacking rod, and the lower end of the cam jacking rod extends out of the outer barrel and is connected with a compression plate. The mechanical type external chest compression device is simple in structure, easy to machine and produce, low in cost, small in size, compact in structure, low in weight, convenient, fast, few in transmission components, high in transmission efficiency, low in energy loss and beneficial to battery life.

Description

technical field [0001] The invention relates to the technical field of medical emergency equipment, in particular to a mechanical chest compression device. Background technique [0002] Mechanical cardiopulmonary resuscitation equipment, with its portability and mobility, is widely used as a means of replacing manual CPR in all stages of first aid, such as pre-hospital and in-hospital, and can effectively reduce compression interruptions, ensure compression frequency, The depth of compression and the rebound force of the thorax produce a good effect of emergency resuscitation and improve the efficiency of medical assistance. [0003] Mechanical cardiopulmonary resuscitation equipment is mainly divided into pneumatic cardiopulmonary resuscitation devices and electric cardiopulmonary resuscitation devices according to their different power sources: [0004] The main features of the pneumatic cardiopulmonary resuscitation device (according to the control method can be divided ...
