US 11,596,575 B2 · CPR apparatus and method

Abstract

A CPR apparatus includes a chest compression unit and a means for mounting the chest compression unit on a patient. The chest compression unit includes a plunger disposed in a housing. At its one end extending from the housing the plunger has a compression member. The plunger is driven in a reciprocating manner by a reversible electromotor via a mechanism for translating rotational motion to linear motion or by a linear induction electromotor. The chest compression unit includes an electromotor control unit including a microprocessor, a first monitor for monitoring the position of the plunger in respect of the housing and a second monitor for monitoring the position of the plunger in respect of the mechanism for translating rotational motion to linear motion or the rotor of the linear induction electromotor. The monitored positions are communicated to the electromotor control unit. Also disclosed is a corresponding CPR method.

Dependent claims

A cardiopulmonary resuscitation (CPR) apparatus, comprising:

a chest compression unit comprising:
a housing;
a plunger disposed in the housing, the plunger having a compression member at one end of the housing that extends from the housing, wherein the plunger is configured to be driven in a reciprocating manner, and wherein the compression member is configured to deliver compressions of varying depths to a patient's chest;
and
a control unit that includes a microprocessor configured to cause the plunger to perform a series of CPR compressions including a plurality of soft start chest compressions and at least one compression at a full compression depth, the plurality of soft start chest compressions including a continuous increase from a first compression having a depth of less than the full compression depth to a final compression having a depth of the full compression depth, wherein during each compression the control unit is configured to drive the plunger until a desired compression depth is reached.
