Manikin sensing pads and liners in an AED training system

1. An improved automated external defibrillator training pad and liner assembly and an automated external defibrillator training device, the assembly having an electrical lead connection supported on the training pad, the training pad having an adhesive surface and a contact surface, the liner having an engagement surface for repeated adhesive engagement with a portion of the training pad adhesive surface during storage of the assembly, the training pad adhesive surface having an electrical-mechanical switch with a protruding portion protruding from the training pad and interconnected with the electrical lead connection, and the liner having a recess positioned for engagement adjacent the electrical-mechanical switch to prevent the protruding portion of the electrical-mechanical switch from being compressed or depressed by the liner during storage of the assembly;

wherein the protruding portion of the electrical-mechanical switch extends in a direction away from the training pad adhesive surface and out of a plane of the training pad adhesive surface;

wherein the electrical-mechanical switch is depressed for activation of the electrical lead connection when the adhesive surface is adhered to a generally smooth and continuous surface of a training manikin; and

wherein the automated external defibrillator training device recognizes an initial and proper adherence of the adhesive surface of the training pad to activate the automated external defibrillator training device, and once activated, the automated external defibrillator training device ignores further deactivation signals from the training pad.

2. The improved automated external defibrillator training pad and liner assembly of claim 1 , wherein the recess is an opening in the liner sized for non-interference with the protruding portion of the electrical-mechanical switch during storage of the assembly and the opening through the liner has a height which is larger than a height of the switch supported on the adhesive surface of the pad.

3. The improved automated external defibrillator training pad and liner assembly of claim 1 , wherein the recess is a depression formed in the liner sized for non-interference with the electrical-mechanical switch during storage of the assembly and the depression in the liner has a height which is larger than a height of the switch supported on the adhesive surface of the pad.

4. The improved automated external defibrillator training pad and liner assembly of claim 1 , wherein the liner is configured for reattachment to the pad to ensure alignment of the electrical-mechanical switch adjacent the recess during storage of the assembly.

5. An improved automated external defibrillator training system, having an automated external defibrillator training device, a training manikin and a training pad having an adhesive surface supporting a protruding switch which switch is activated upon physical contact to depress or compress the protruding switch against the training manikin during adhering of the adhesive surface of the training pad to the training manikin; and

wherein the automated external defibrillator training device recognizes an initial and proper adherence of the adhesive surface of each training pad to activate the automated external defibrillator training device, and once activated, the automated external defibrillator training device ignores further deactivation signals from each training pad.
