Abstract: An active backboard that can assist with adjusting a patient on the backboard to ensure that the backboard is correctly aligned for a compression mechanism of an upper portion of a mechanical cardiopulmonary resuscitation (CPR) device to perform compressions. The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard.

Abstract: Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

Abstract: A mechanical cardiopulmonary resuscitation (“CPR”) device includes a compression mechanism, a support structure, and a light source. The compression mechanism is configured to perform successive CPR compressions to a chest of a patient and includes, in one example configuration, a translucent suction cup, a piston, and a driver coupled to the piston and configured to extend the piston toward the chest of the patient and retract the piston away from the chest of the patient. The support structure is configured to position the compression mechanism over the chest of the patient. The light source is configured to illuminate the translucent suction cup.
