Cardiac resuscitation automatic pressing machine

Abstract

The invention provides a cardiac resuscitation automatic pressing machine. The machine includes a fixed rack, bolts, sawtooth plates, guide posts, movable pins and a press center and is characterizedin that a load-sharing planetary gear train is driven by a servo motor and further a disk cam mechanism with a translating follower is driven so as to enable a push rod to achieve an effect of reciprocating motion with a move stroke being 5cm; the movable pins on both sides of the fixed rack are telescopic and the telescoping stroke in a working state is 0-21cm and the step length is 1cm. Therefore, effects of uniform and adjustable pressing depth, identical pressing reciprocating time and adaptability to individuals of different fat and thin levels are achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic cardiac resuscitator pressing machine. Background technique [0002] Traditional chest resuscitation mostly uses the operator's hands on the chest compression part of the patient to press rhythmically to achieve. Requirements for pressing: the depression depth of pressing is 3-5cm, and the pressing frequency is 100-120 times / min, so the operation intensity is relatively high. In the actual operation, often because the operator's arm is not straight, resulting in uneven force on the palm; or because the operator's physical exertion is too large, the operator needs to be replaced frequently and many other reasons, which affect the effect of pressing, especially prone to rib fractures and other complications. For example, the patent No. CN201420660150.0 discloses a "portable external chest electric presser", which includes a shell, a movable connecting arm...

Problems solved by technology

In the actual operation, often because the operator's arm is not straight, resulting in uneven force on the palm; or because the operator's physical exertion is too large, the operator needs to be replaced frequently and many other reasons, which affect the effect of pressing, especially prone to rib fractures and other complications

For example, the patent No. CN201420660150.0 discloses a "portable external chest electric presser", which includes a shell, a movable connecting arm, a concave positioning part, a fixed connecting arm, a chest and back support plate, a positioning ball head, a soft pressing head, Servo motors, etc., have good compression consistency, simple structure and portability, but they take up a lot of space, cannot adjust the compression depth, and lack universal applicability for different fat and thin individuals. Therefore, a new type of chest compression device is needed
