MECHANICAL CHEST COMPRESSION PLUNGER ADAPTER AND COMPRESSION PAD

摘要

A plunger adapter and a detachable compression pad for piston driven chest compression devices optimizes the application of chest compressions to a fixed location on a patient's chest. The detachable compression pad may be removably secured to the patient above the patient's sternum to ensure that the compression pressure from the piston through the piston adapter is applied to a fixed location on the patient's chest. As the plunger and plunger adapter retract from the chest, the compression pad remains fixed to the patient's chest, and as the plunger and plunger adapter extend from the chest compression unit for subsequent compression strokes, the distal end of the plunger adapter reengages the compression pad to apply compression to a fixed location on the patient's chest.

主权项

1. A method of performing automated chest compression on a patient having a chest, comprising the steps:
providing a mounting structure; providing a chest compression unit operably connected to the mounting structure, the chest compression unit including a reversible motor, a plunger having a distal end and a proximal end, the proximal end of the plunger operably coupled to the reversible motor, the motor operable to extend and withdraw the distal end of the plunger out of and into the housing to perform chest compression on the patient; providing an motor control unit operably connected to the motor and including a microprocessor to control the motor to extend and withdraw the plunger; securing a compression monitor to the patient at a preselected force application location; providing a plunger adapter secured to the distal end of the plunger, the plunger adapter having a socket sized to engage the compression monitor during chest compressions; securing the chest compression unit and mounting structure about the patient's chest such that the socket engages the compression monitor and is operable to perform chest compressions; initiating chest compressions through the motor control unit.
