Abstract

A portable defibrillator having a defibrillator circuit, a body for housing a defibrillator circuit, and a hook coupled to the body is disclosed. The hook is positionable in an extended position and a retracted position. When in the extended position, the hook is poised to receive a member of an external structure, such as a gurney or hospital bed, and thereby enables the defibrillator to hang from the external structure. The body of the defibrillator may provide a deflectable member positioned to engage a depression formed in the outer surface of the hook when the hook is in the extended position, thus retaining the hook in the extending position. In a similar fashion, the deflectable member may be used to retain the hook in the retracted position. A user interface panel may be disposed on the front of the body of the defibrillator for providing information to and receiving information from a user of the defibrillator. The user interface panel is oriented on the front of the body to face at an upward angle relative to the base. Furthermore, electrical connection sites for coupling external electronic instruments to the defibrillator may also be provided. The electrical connection sites are recessed back from the front of the defibrillator and are further disposed on a panel extending outward from a side of the defibrillator. A method of suspending a portable defibrillator from an external structure by coupling a selectively positionable hook to the defibrillator and hanging the defibrillator from the external structure via the hook is also disclosed.
