The Innosonian America-S16103 Body Frame is the central structural chassis designed specifically for the Brayden Pro Adult CPR training manikin series. Manufactured from high-impact, durable polymer, this replacement torso housing forms the internal skeleton that holds the manikin's electronic sensor networks, rib assembly, spring mechanisms, and Bluetooth connectivity modules in precise alignment. Installing an OEM replacement body frame restores structural rigidity, corrects internal component misalignment from heavy classroom use, and extends the operational life of high-performance CPR training simulators.
