Abstract

An electro-mechanical CPR device (10, 11) for applying cardiopulmonary compressions to a chest of a patient employs a chest compressor (20), one or more straps (40) and a compression controller (30). Chest compressor (20) is self- supportable upon the chest of the patient and includes assembly an electric motor (50), a mechanical transmission (60), a linear actuator (70) and a plunger (80) mounted within a housing (100) wherein the linear actuator (70) converts rotational motion generated by the electric motor (50) and the mechanical transmission (60) into linear motion of the plunger (80) for applying a compressive force (21) to the chest of the patient. Strap(s) (40) wrap around the patient and is(are) coupled to chest compressor (20). Compression controller (30) is external to the chest compressor (20) and applies power and controls signals to the electric motor (50).

Description

technical field

[0001] The present invention generally relates to electromechanical cardiopulmonary compression ("CPR") devices. Specifically, the present invention relates to an electromechanical CPR apparatus comprising a chest depressor light enough to be self-supportingly placed on a patient's chest and a compression controller for operating the chest depressor to produce High quality compressions for the patient. Background technique

[0002] A chest compression cycle consists of a compression phase and a release phase. Specifically, the compression phase involves chest compressions in the sternal region to squeeze the ventricles, thereby allowing oxygenated blood to flow to vital organs, and the release phase involves chest expansion, thereby refilling the ventricles with blood. For high-quality chest compressions, it is important that a sufficient amount of blood is returned to the ventricles during the release phase. However, if a heavier chest compressor is seate...
