Manual CPR or CCC continuous chest compression assist device

摘要

The invention is a manual CPR or CCC continuous chest compression assist device for use on a person suffering cardiac arrest. The assist device has a compressible body structure and an audible signal element, visual signal assembly or both. The audio signal element is interposed in the body structure to announce or generate an audible sound or “click” at a predetermined deflection of the compressible portions. The visual signal assembly is interposed in the body structure to announce or generate a visible light at a predetermined deflection of the compressible portions. The activation of the visual or audio signal corresponds to a predetermined deflection of the compressible portions pressing against the breastbone and alerts the person administering to initiate decompressing to relax the body structure for the next compression, upon relaxation the device decompresses and a second audible or visual signal or both indicates a reset of the device.

主权项

1. A manual CPR or CCC continuous chest compression assist device for use on a person suffering cardiac arrest, the assist device comprises:
a compressible body structure having a compressible upper body portion to which a person administering CPR or CCC places his hand to exert a downward force and a bottom compressible portion which is positioned over a breastbone of the person suffering cardiac arrest, the bottom compressible portion being aligned with the upper compressible portion; an audio signal element is interposed in the body structure to announce or generate an audible sound or “click” at a predetermined deflection distance of the compressible portions wherein the audio signal element is a domed plate or disk supported on the perimeter by the compressible body structure and with a center dome positioned and suspended in a cavity or hollow to allow the dome to snap as the deflection distance is achieved to annunciate a first signal; wherein an activation of the audio signal element corresponds to the predetermined deflection distance of the compressible portions pressing against the breastbone and alerts the person administering to initiate decompressing to relax the body structure for the next compression; and wherein the audio signal element announces a first audible sound or “click” as the first signal at the predetermined deflection distance during a compression and upon relaxation of downward force the audio signal element is reset and the device is ready for the next compression and as the compressible body structure moves toward an uncompressed condition as the downward force is removed and a second audible sound or “click” occurs as a second signal is made to signal a reset of the device, wherein the first signal and the second signal repeat on each successive compression and decompression to the predetermined deflection distance.
