Abstract
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.
