The Innosonian America-S13104 Body Frame is the primary internal structural chassis engineered specifically for the Brayden Advanced (LED) Adult CPR training manikin series. Manufactured from high-impact, medical-grade polymer, this heavy-duty torso housing forms the essential backbone that holds the manikin's internal LED lighting circuits, blood circulation flow indicators, chest compression sensors, and recoil spring mechanisms in exact anatomical alignment. Replacing a cracked, fatigued, or damaged body frame restores full structural rigidity, ensures proper contact across internal electronic sensor arrays, and extends the service life of high-use CPR simulation equipment.
