US 2019/0053975 A1 · CPR CHEST COMPRESSION SYSTEM

Abstract

In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.

Dependent claims

A mechanical cardiopulmonary resuscitation (“CPR”) device, comprising:

a piston;
a driver coupled to the piston configured to extend and retract the piston;
and
a controller configured to cause the driver during a session to at least:
position the piston at a reference position;
extend the piston from the reference position to a compression position to compress a chest of a patient;
return the piston from the compression position to the reference position;
retract the piston from the reference position to a retreat position, wherein the retreat position includes the piston at a distance away from the reference position whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position, further wherein the piston is retracted to the retreat position at least once before the end of the session;
and
return the piston from the retreat position to the reference position.

7 more elements

A non-transitory computer-readable storage medium storing one or more programs which, when executed by at least one processor of a system to assist a rescuer to perform, during a session, successive cardiopulmonary resuscitation (“CPR”) compressions on a chest of a patient by using a system that includes a piston and a driver, the programs result in operations comprising:

positioning the piston at a reference position;
extending the piston from the reference position to a compression position to compress a chest of a patient;
returning the piston from the compression position to the reference position;
retracting the piston from the reference position to a retreat position, wherein the retreat position includes the piston at a distance away from the reference position whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position, further wherein the piston is retracted to the retreat position at least once before the end of the session;
and
returning the piston from the retreat position to the reference position.
