Abstract

A medical device having a battery pack comprising an indicator, wherein the battery pack indicator indicates the status of the battery pack when the battery pack is disassociated from the medical device and indicates the status of the medical device when associated with the medical device.

Claims

1. An automated external defibrillator, comprising:

a removable battery pack comprising an indicator, wherein the indicator comprises a visual output or an audible output; and

defibrillation circuitry powered by the removable battery pack, the defibrillation circuitry in conjunction with programming running thereon configured to deliver a therapeutic shock,

wherein the indicator comprises the dual capability of indicating a status of the removable battery pack when the removable battery pack is not connected to the defibrillation circuitry and indicating a status of the defibrillation circuitry and the removable battery pack when the battery pack is connected to the defibrillation circuitry, and wherein the automated external defibrillator comprises a battery well constructed and arranged to house the removable battery pack.

2. The automated external defibrillator of claim 1, wherein the visual output is a light.

3. An automated external defibrillator, comprising:

a removable battery pack comprising an indicator, wherein the indicator comprises a visual output or an audible output,

defibrillation circuitry powered by the removable battery pack and comprising an indicator, the defibrillation circuitry in conjunction with programming running thereon configured to deliver a therapeutic shock,

wherein the removable battery pack indicator indicates the status of the removable battery pack when the removable battery pack is not connected to the defibrillation circuitry, and

wherein the defibrillation indicator indicates the status of the defibrillation circuitry and the removable battery pack when the removable battery pack is connected to the defibrillation circuitry, and wherein the automated external defibrillator comprises a battery well constructed and arranged to house the removable battery pack.

4. The automated external defibrillator of claim 3, wherein the visual output is a light.
