Patent ID: 8888725

Claim:
An automated chest compression device comprising: a mounting structure; a chest compression unit including a reversible electromotor, a plunger having a distal end and a proximal end, the proximal end of the plunger operably coupled to the reversible electromotor, the distal end of the plunger extending from and withdrawing into the housing, the chest compression unit secured to the mounting structure to engage a patient and perform chest compressions; an electromotor control unit operably connected to the motor and including a microprocessor to control the electromotor and the plunger; a plunger adapter secured to the distal end of the plunger; a compression pad removably engaging the plunger adapter; wherein the plunger adapter and the compression pad include complimentary concave and convex elements, respectively, to removably engage the plunger adapter with the compression pad; a compression monitor secured to the patient at a preselected force application location; and wherein the concave element in the plunger adapter is a socket sized to engage the compression monitor during cyclic chest compressions.
