Abstract
A system and method for mechanical CPR can include a device for providing compressive force to various locations on a patient, and biological monitoring systems to measure the effectiveness of the various locations of compressive force in pumping blood through the patient. The system can also include providing decompressive force to increase the efficacy of blood flow.
Core Innovation
The invention relates to a system for providing personalized Cardiopulmonary resuscitation (CPR) using personalized mechanical CPR. One or more pistons are configured to provide a compressive force at a plurality of locations on a patient, and the system can apply compressive force in different force vectors depending on the piston configuration.
The system includes one or more biological monitoring systems configured to measure feedback from one or more biological systems as the compressive force is applied at the plurality of locations. A processor compares a first feedback associated with a first location to a second feedback associated with a second location in order to determine which location and associated behavior should be used during the CPR.
The invention further includes approaches for active decompression and for varying compression/decompression patterns across locations. The system can include active decompression using suction cups/adhesive and can be configured for sequential multi-location compression-decompression behavior, including multi-piston or multi-head configurations and controllable piston behavior such as an adjustable piston angle/vector.
Claims Coverage
The independent claim(s) define a personalized mechanical CPR system with multiple compression locations, biological monitoring feedback, and a processor that compares feedback between locations. The core independent structure is refined by dependent claims adding decompressive force, specific compression mechanical components, and conditions for performing the comparison.
Piston-based multi-location compressive force
One or more pistons configured to provide a compressive force at a plurality of locations on a patient.
Biological monitoring feedback during compression
One or more biological monitoring systems configured to measure feedback from one or more biological systems as the compressive force is applied at the plurality of locations on the patient.
Processor comparing feedback between compression locations
A processor configured to compare a first feedback as the compressive force is applied at a first location of the plurality of locations on the patient to a second feedback as the compressive force is applied at a second location of the plurality of locations on the patient.
Sequential decompressive force
The system includes one or more pistons configured to deliver a decompressive force to the patient sequentially with the pistons that deliver a compressive force.
Compression belt and rotary compression unit
The system includes a compression belt and a rotary compression unit configured to apply compression to a patient.
Rotary platform mounting for the rotary compression unit
A rotary platform on the compression belt, with the rotary compression unit mounted on that rotary platform.
Backboard and frame for mounting pistons
A backboard and a frame, with the one or more pistons mounted to the frame.
Feedback comparison during provision of personalized CPR
The processor is configured to compare first and second feedbacks during provision of personalized CPR.
Overall claim coverage centers on personalized CPR delivered by pistons applying compressive force at multiple chest locations, with biological monitoring measuring feedback during application. A processor compares feedback between locations, and dependent claims additionally cover sequential decompressive force, specific belt/rotary compression hardware, piston mounting structures, and clarifying that feedback comparison occurs during personalized CPR.
