Heart compression simulation device

A heart compression simulation device comprising:

• (a) a base (16);
• (b) a spring (10) extending upwardly from the base (16);
• (c) an actuator (2) disposed atop the spring (10), the actuator (2) and base (16) together sandwich the spring (10), wherein the actuator (2) can move between a starting position wherein the actuator (2) is positioned above the base (16) and an end position wherein the actuator (2) is pushed down near or contacting the base (16), the actuator (2) is biased in the starting position caused by the spring (10);
• (d) a first pedestal (17A) and a second pedestal (17B) each disposed atop the base (16), the pedestals (17) are positioned opposite each other and outside of the actuator (2);
• (e) a first set of actuator prongs (22A) disposed on the actuator (2) facing the first pedestal (17A) and a second set of actuator prongs (22B) disposed on the actuator (2) facing the second pedestal (17B);
• (f) a first hub (47A) pivotally attached to the first pedestal (17A) and a second huh (47B) pivotally attached to the second pedestal (17B);
• (g) a first detent (21A) disposed on the first hub (47A) and positioned below the first set of actuator prongs (22A) and a second detent (21B) disposed on the second hub (47B) and positioned below the second set of actuator prongs (22B), the detents (21) are adapted to engage the respective sets of actuator prongs (22) when the actuator (2) is moved to the end position, the detents (21) provide resistance when the actuator (2) is moved to the end position, wherein when the actuator (2) is moved to the end position and the detents (21) engage the respective sets of actuator prongs (22) a sensation is produced;
• wherein the hubs (47) can each pivot between a disengaged position wherein the hubs (47) are positioned to allow the detents (21) to engage the respective sets of actuator prongs (22) and an engaged position wherein the hubs (47) are positioned to keep the detents (21) out of range of the respective actuator prongs (22);
• and
• (h) a lock-out mechanism configured to pivot the hubs (47) from the disengaged position to the engaged position and secure the hubs (47) in the engaged position thereby keeping the detents (21) out of range of the respective actuator prongs (22), the lock-out mechanism is activated when the actuator (2) is moved to the end position.

A detent mechanism device comprising:

• (a) a base (16);
• (b) a spring (10) extending upwardly from the base (16);
• (c) an actuator (2) disposed atop the spring (10), the actuator (2) and base (16) together sandwich the spring (10), wherein the actuator (2) can move between a starting position wherein the actuator (2) is positioned above the base (16) and an end position wherein the actuator (2) is pushed down near or contacting the base (16), the actuator (2) is biased in the starting position caused by the spring (10);
• (d) a first pedestal(17A) disposed atop the base (16) in proximity to the actuator (2);
• (e) a first set of actuator prongs (22A) disposed on the actuator (2) facing the first pedestal (17A);
• and
• (f) a first detent (21A) disposed on the first pedestal (17A) and positioned below the first set of actuator prongs (22A), the first detent (21A) is adapted to engage the first set of actuator prongs (22A) when the actuator (2) is moved to the end. position, the first detent (21A) provides resistance when the actuator (2) is moved to the end position, wherein when the actuator (2) is moved to the end position and the first detent (21A) engages the first set of actuator prongs (22A) a sensation is produced.
