Abstract: A piston assembly with a transversely removable suction cup, the piston assembly having a piston rod, a flange at an end of the piston rod, and a suction cup removably secured to the end of the piston rod. The piston rod has a longitudinal axis defining a longitudinal direction and a transverse direction that is substantially perpendicular to the longitudinal direction. The flange has a width in the transverse direction that is greater than a width of the piston rod in the transverse direction. The suction cup includes a receptacle configured to accept and secure the flange within the receptacle. The receptacle has an opening allowing the flange to be accepted into the receptacle in the transverse direction and to be removed from the receptacle in the transverse direction.

Abstract: Examples of the disclosure are directed to adjustable back plates or backboards for a mechanical compression device to accommodate different patient sizes and/or for ease of storage. Examples of the disclosure includes back plates that can be folded, pieced together, or otherwise have a variable distance between connectors that attach to legs of a chest compression device. Examples also include back plates which may have two sides, such as an adult patient side and a pediatric patient side, to accommodate different patient sizes.

Abstract: A CPR device having a base member configured to be placed underneath a patient, a chest compression mechanism configured to deliver CPR chest compressions to the patient, a support leg configured to support the chest compression mechanism at a distance from the base member, a clamp mechanism coupled to the support leg, and a release mechanism coupled to the support leg and the clamp mechanism. The clamp mechanism is configured to attach the support leg to a lock component of the base member in a latch-closed configuration and to release the support leg from the lock component in a latch-open configuration. The clamp mechanism is further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism without the release mechanism being pulled away from the base member.

Abstract: Examples of the disclosure include a universal suction cup for a cardiopulmonary resuscitation device having a first circular member extending from a piston-facing surface, and a second circular member concentric to the first circular member extending from the piston-facing surface, the second circular member having a diameter that is less than the first circular member. Example of the disclosure also include suction cups with rigid members to reduce the amount of force necessary to attach the suction cup to a patient. Examples of the disclosure also include a mechanical compression device which can detect the type of suction cup attached to a compression member and activate particular features or settings based on the attached suction cup.

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: 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.

Abstract: A cardiopulmonary resuscitation (CPR) chest compression device, including a chest compression component structured to deliver chest compressions to a patient, and a controller electrically coupled to the chest compression component. The controller operates the chest compression component to switch between operating at least in a first mode for a first time period and a second mode for a second time period. The first mode includes compressing a chest of a patient at a first rate of compressions, at a first depth for each compression, and a first duty cycle, and the second mode includes compressing a chest of a patient at a second rate of compressions, at a second depth for each compression, and a second duty cycle, at least one of the second rate, the second depth, and the second duty cycle is different from the first rate, the first depth, and the first duty cycle.
