Abstract: A cardio-pulmonary compression system includes a compression device (110), a supporting mechanism (120) coupled to the compression device and a feedback sensor (104) configured to measure interactions between a patient and the compression device. A control unit (112) is configured to receive input from the feedback sensor and adjust operating parameters of the compression system to meet a target parameter during operation of the compression device.

Abstract: A cardio-pulmonary compression board includes a board (10) configured for a patient. A leg (20) is pivotally connected to the board, and the leg includes a free end portion having a mechanical feature (35) configured to be received in a compression device to adjustably secure the compression device at a distance from the board in an operational position. A locking mechanism (32, 42) is configured to releasably maintain the leg in the operational position, which is transverse to a plane of the board.

Abstract: A cardio-pulmonary compression device includes a motor (11) having a rotating portion, and a ball nut (12) mounted on the rotating portion and configured to rotate with the rotating portion. A ball screw (13) is received in the ball nut such that rotation on the ball nut advances and/or retracts the ball screw in accordance with a direction of the motor. A pad assembly (15) is coupled to an end portion of the ball screw such that longitudinal motion of the ball screw imparts a compression cycle to a patient.

Abstract: An electro-mechanical CPR device (10, 11) for applying cardiopulmonary compressions to a chest of a patient employs a chest compressor (20), one or more straps (40) and a compression controller (30). Chest compressor (20) is self-supportable upon the chest of the patient and includes assembly an electric motor (50), a mechanical transmission (60), a linear actuator (70) and a plunger (80) mounted within a housing (100) wherein the linear actuator (70) converts rotational motion generated by the electric motor (50) and the mechanical transmission (60) into linear motion of the plunger (80) for applying a compressive force (21) to the chest of the patient. Strap(s) (40) wrap around the patient and is(are) coupled to chest compressor (20). Compression controller (30) is external to the chest compressor (20) and applies power and controls signals to the electric motor (50).

Abstract: The invention relates to an automated CPR device for performing automated chest compressions of a patient. The CPR device is provided with display processing electronics for processing information data so that display content associated with the information data can be displayed in different rotated orientations so that the information can be oriented correctly relative to a user's viewing direction. The CPR device is configured with an orientation button for activating rotation of the displayed information. The orientation button is configured so that the location of the button relative to display content, at least along a single dimension, is the same. For example, the orientation button may be located adjacent to the middle of an edge of the display so that the button remains located adjacent to information located in the center of the display irrespective of the displayed orientation of the information, irrespective of the two orientations.

Abstract: A multi-function defibrillator having an improved mode selection switch (200). When the switch is rotated to select the desired mode of operation, such as defibrillation, cardio-version, pacing, or monitoring, the positioning of those modes related to the Off position (205) is based on the time-criticality of the corresponding therapy. The most time-critical therapy is located closest to the Off position, and the least time-critical therapy is located furthest away from the Off position.
