An improved power supply adapter is provided for plug-in connection to a standard AC power supply receptacle, and to provide a DC voltage to an associated electronic instrument. The power supply adapter comprises a relatively compact case having an end face with a plurality of conductive prongs protruding therefrom for plug-in connection to an AC receptacle, such as one socket of a standard duplex or quad wall outlet or the like. An AC adapter assembly is mounted within the adapter case with the components of the AC adapter assembly arranged generally in-line between the conductive prongs and a power cord adapted for connection to the associated electronic instrument. This in-line geometry permits the adapter case to have a relatively narrow width and low profile height conforming with a single electrical socket, whereby plug-in connection of the adapter to an electrical socket does not obstruct access to adjacent sockets. In addition, in a preferred form, the adapter case further includes a mounting clip for convenient removable connection to the associated electronic instrument when the power supply adapter is not in use.

An adapter plug clip is provided for convenient and secure temporary support of an electrical plug associated with an electronic instrument, particularly wherein the plug is formed as part of a relatively heavy AC/DC plug-in power supply adapter. The adapter plug clip is designed for clip-on mounting to a support structure, such as a bracket arm of a clamp fixture having an electronic instrument such as a medical fluid infusion pump mounted thereon. The adaptor plug clip includes a face plate having a visually identifiable pattern of holes formed therein for seated reception of the conductive prongs of the electrical plug, thereby providing a stable temporary plug mounting site.

An improved battery pack is provided for short term battery power operation of a medical instrument such as an infusion pump. The battery pack comprises a substantially closed and compact housing one or more rechargeable batteries inaccessibly encased therein, with the battery pack housing being adapted for mounting directly onto the casing of an electronic medical instrument. The batteries are mounted on a base plate beneath a foil shield and a housing cap, both of which are attached to the base plate in a manner precluding nondestructive removal thereof and thereby substantially preventing access to the batteries. The assembled battery pack housing includes seal members for preventing passage of any gases discharged from the batteries into the medical instrument casing, and further defines at least one vent for exhaust passage of such gases to the exterior of the battery pack and medical instrument.
