Abstract
Devices and methods for CPR chest compression with active decompression.
Claims31
A system for augmenting release of the chest of a cardiac arrest patient during CPR with automated chest compressions, the system comprising:
- an automated chest compression device;
- and
- an augmented release device configured to be coupled with the automated chest compression device, the augmented release device comprising one or more resilient portions configured to conform to the chest of the cardiac arrest patient during the CPR with the automated chest compressions,
- at least a part of an inner surface of the one or more resilient portions configured to be adhered to the chest of the patient during the CPR with the automated chest compressions,
- wherein, for a chest compression cycle having one compression phase and one release phase, the one or more resilient portions have a capacity to transition between a compressed state during administration of the compression phase of the chest compression cycle and an uncompressed state during the release phase of the chest compression cycle,
- wherein the augmented release device is configured to augment the release of the chest of the patient during the CPR with the automated chest compressions by exerting an expansive force by pulling on a thorax of the patient to hasten expansion of the chest during the release of the chest relative to unaided expansion of the chest, wherein the expansive force is exerted by decompression of the one or more resilient portions upon the release of the chest during the release phase of the chest compression cycle, and
- wherein two ends of the one or more resilient portions are configured to be capable of overlapping each other in an area of a sternum of the patient.

A system for augmenting release of the chest of a cardiac arrest patient during CPR with automated chest compressions, the system comprising:
- an automated chest compression device;
- and
- an augmented release device configured to be coupled with the automated chest compression device, the augmented release device comprising one or more arcuate bands configured to conform to the chest of the cardiac arrest patient during the CPR with the automated chest compressions,
- at least a part of an inner surface of the one or more arcuate bands configured to be adhered to the chest of the patient during the CPR with the automated chest compressions,
- wherein, for a chest compression cycle having one compression phase and one release phase, the one or more arcuate bands have a capacity to transition between a compressed state during administration of the compression phase of the chest compression cycle and an uncompressed state during the release phase of the chest compression cycle,
- wherein the augmented release device is configured to augment the release of the chest of the patient during the CPR with the automated chest compressions by exerting an expansive force by pulling on a thorax of the patient to hasten expansion of the chest during the release of the chest relative to unaided expansion of the chest, wherein the expansive force is exerted by decompression of the one or more arcuate bands upon the release of the chest during the release phase of the chest compression cycle, and
- wherein two ends of the one or more arcuate bands are configured to be capable of overlapping each other in an area of a sternum of the patient.
