Abstract

A floating mounting structure is provided for protectively mounting an electronic circuitry system within an automated external defibrillator case. A method of assembling an electronic circuitry system within an automated external defibrillator case is also provided. A circuit mounting system is utilized and includes a spacer and a shock mount. The spacer may include cut out portions to accommodate raised elements on circuit boards of the electronic circuitry system. The spacer is disposed between two circuit boards which may be affixed to each other. The affixed circuit boards and spacer are folded within the shock mount and disposed within the defibrillator case. Alternatively, a single mounting structure may be used to secure and protect the circuit board within the defibrillator case. A shielding may be present on an exterior surface of the foam mounting structures to protect the electronic circuitry from electromagnetic interference.

Claims

1. An automated external defibrillator system, comprising:

an automated external defibrillator housing;

an electronic circuitry system disposed within the housing; and

a foam mounting structure protectively disposed about the electronic circuitry system, the foam mounting structure further including an electromagnetic shielding material attached to an exterior surface thereof.

2. The automated external defibrillator system of claim 1, wherein the electronic circuitry system includes first and second circuit boards.

3. The automated external defibrillator system of claim 2, further comprising a foam spacer disposed between the first and second circuit board.

4. The automated external defibrillator system of claim 3, wherein the foam spacer is a low density die cut foam.

5. The automated external defibrillator structure of claim 1, wherein the shielding material is aluminum foil.

6. The automated external defibrillator system of claim 1, wherein the foam mounting structure further includes a plurality of scorings, thereby defining a series of panels, the panels accommodating horizontal and vertical dimensions of an interior portion of the automated external defibrillator housing.

7. The automated external defibrillator system of claim 1, wherein the foam mounting structure is a closed cell low density polyethylene.
