System and apparatus for controlled activation of acute use medical devices

An acute use medical device comprising:

• a power source;
• a therapy unit;
• a switching circuit having first and second inputs and having an output coupled to said therapy unit;
• a gating element having an input coupled to said power source and an output coupled to said first input of said switching circuit, said gating element configured to gate power to said switching circuit;
• and
• a sensing element coupled to said second input of said switching circuit, said sensing element configured to:
• change from a first state to a second state indicating an activation condition of the acute use medical device;
• enable an operation interval of said switching circuit;
• and
• transmit a signal to said switching circuit during said second state, said switching circuit further configured to transmit power to said therapy unit upon receipt of a pre-determined number of said signals from said sensing element.

An integrated activation system for an acute use device sharing a power source, the activation system comprising:

• a switching circuit having a first input coupled to the power source and an output coupled to said therapy unit and having a second input;
• a gating element having first and second inputs and an output, said first input of said gating element coupled to said power source, said output of said gating element coupled to said first input of said switching circuit, said gating element configured to gate power to said switching circuit during a first state;
• and
• a sensing element coupled to said second input of said switching circuit and said second input of said gating element and configured to:
• detect a first signal indicating an activation condition;
• enable an operation interval of said switching circuit;
• and
• transmit a second signal to said switching circuit upon detecting said first signal, said switching circuit configured to transmit power received from said gating element to said therapy unit upon receipt of a predetermined number of said second signals.
