Abstract

A system for providing battery power to a portable defibrillator that includes a first housing having a generally vertical first sidewall (32). The system comprises battery pack (12) that includes a second housing having a second sidewall (38), battery means (80, 82) mounted within the second housing, and first electrical connector means (66) mounted in and extending through the second housing and electrically connected to the battery means. The system further comprises means forming grooves (46, 50) along the upper and lower edges of the first sidewall, and tongue means (40, 42) extending from the second sidewall, the tongue means being shaped to be slidingly received between the groove means to mount the battery pack to the defibrillator. A latch (68) is provided for latching the tongue means against lengthwise motion when the tongue means is received between the groove means. Second electrical connector means (62) are mounted adjacent the first sidewall between the groove means and is adapted to engage the first electrical connector means when the battery pack is mounted to the defibrillator. The battery pack may comprise rechargeable batteries and a battery charger (104) mounted within the second housing that is adapted to recharge the batteries upon the receipt of either an AC or a DC power signal.

Claims

1. A system for providing battery power to a portable defibrillator that comprises a first housing having a generally vertical first sidewall, the system comprising:

(a) a battery pack including a second housing having a second sidewall, battery means mounted within the second housing, and first electrical connector means mounted in and extending through the second housing and electrically connected to the battery means;

(b) upper groove means extending along the upper edge of the first sidewall and forming a downwardly facing horizontal groove;

(c) lower groove means extending along the lower edge of the first sidewall and forming an upwardly facing horizontal groove;

(d) tongue means extending from the second sidewall and shaped to be slidingly received between the upper and lower groove means to mount the battery pack to the defibrillator;

(e) latch means for latching the tongue means against lengthwise motion when the tongue means is received between the upper and lower groove means;

(f) second electrical connector means extending from the first sidewall between the upper and lower groove means and adapted to engage the first electrical connector means when the battery pack is mounted to the defibrillator.

2. The system of claim 1, wherein the battery means comprises rechargeable battery means, and wherein the battery pack includes a battery charger mounted within the second housing and a charging jack extending through the second housing and electrically connected to the battery charger.

3. The system of claim 2, wherein the battery charger is adapted to recharge the rechargeable battery means upon receipt of either an AC or a DC power signal through the charging jack.

4. The system of claim 3, wherein the dimensions of the battery pack and defibrillator are approximately equal in directions parallel to the first surface.

5. The system of claim 2, wherein the second electrical connector means comprises a connector assembly mounted adjacent the rearmost edge of the first sidewall, the connector assembly comprising a pair of forwardly projecting conductive pins.

6. The system of claim 5, wherein the tongue means includes a cut-away section adjacent the rearmost edge of the second sidewall, and wherein the first electrical connector means comprises a pair of sockets, the cut-away section and sockets being dimensioned and positioned to receive the connector assembly and pins respectively when the battery pack is mounted to the defibrillator.

7. The system of claim 1, wherein the battery pack is supported entirely through the tongue means when the battery pack is mounted to the defibrillator, such that the battery pack is mounted in a cantilevered fashion from the first sidewall.
