Abstract:
1. A heart compression simulation device comprising: (a) a base; (b) a compression spring extending upwardly from the base; (c) an actuator disposed atop the compression spring, the actuator and base together sandwich the compression spring; wherein the actuator can move between an extended position wherein the actuator is positioned at a starting position above the base, and a fully compressed position wherein the actuator is pushed down to the base, the actuator is biased in the extended position caused by the compression spring; (d) a first pedestal and a second pedestal each disposed atop the base, the pedestals are positioned opposite each other and outside of the actuator; (e) a set of first actuator prongs disposed on the actuator facing the first pedestal and a set of second actuator prongs disposed on the actuator facing the second pedestal; (f) a first hub pivotally attached to the first pedestal and a second hub pivotally attached to the second pedestal; (g) a first leaf spring disposed on the first hub and positioned below the set of first actuator prongs, and a second leaf spring disposed on a second hub and positioned below the set of second actuator prongs, the leaf springs are adapted to engage the respective sets of actuator prongs when the actuator is moved to the fully compressed position, the leaf springs provide resistance when the actuator is moved to the fully compressed position, wherein when the actuator is moved to the fully compressed position and the leaf springs engage the respective sets of actuator prongs a cracking sound is produced; wherein the hubs can each pivot between a disengaged position wherein the hubs are positioned to allow the leaf springs to engage the respective sets of actuator prongs and an engaged position wherein the hubs are positioned to keep the leaf springs out of range of the actuator prongs; and (h) a lock-out mechanism configured to pivot the hubs from the disengaged position to the engaged position and secure the hubs in the engaged position, thereby keeping the leaf springs out of range of the actuator prongs, the lock-out mechanism is activated when the actuator is moved to the fully compressed position.
