Abstract

A compression belt cartridge for use with chest compression devices. The compression belt cartridge has a double-oar shaped belt and a cover plate through which the belt is threaded. The cover plate is provided with hooks and snap latches that fit into a belt drive platform. The cover plate is sized and dimensioned to fit within only selected platforms. The belt attaches to the means for tightening the belt via a spline attached to the belt. The means for tightening a belt then repetitively tightens the belt, thereby accomplishing chest compressions.
