Abstract: An adjustable chest compression device that can adjust to accommodate a variety of patient sizes. The chest compression device can include adjustable support legs structured to support the chest compression mechanism at a distance from the base member and adjust to accommodate a patient size. Another adjustable chest compression device can include adjustable legs that can adjust to accommodate different patient sizes, as well as perform the chest compressions using the adjustable legs. An extension, such as a back plate and/or leg extension can be added to a chest compression device to make the chest compression device taller and/or wider to accommodate larger patients.

Abstract: Techniques and devices for extending a piston, 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, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. 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 CPR machine (100) is configured to perform compressions on a patient's (182) chest that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A compression force may be sensed, and the driving is adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected. An advantage is that a changing condition in the patient or in the retention of the patient within the CPR machine may be detected and responded to.

Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest.

IPC: A61H31/00

Abstract: A cardiopulmonary resuscitation (“CPR”) device that includes a chest compression mechanism, a support structure, and a plurality of inflatable support pads. The chest compression mechanism is configured to deliver CPR chest compressions to a patient. The support structure includes a base member configured to be placed underneath a patient, and a leg configured to support the chest compression mechanism at a distance from the base member. The plurality of inflatable support pads are configured to provide lateral support to a patient's chest during use of the CPR device. Each support pad within the plurality of support pads includes a holder configured to retain and at least partially surround the adjacent support pad.

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.
