Abstract: A battery compartment latch mechanism holds a battery in either a fully loaded or a partially loaded position. The partially loaded position prevents the battery from slipping out of the battery compartment when the battery is being ejected. To hold the battery in the fully loaded position, a latch (66) at one end of a lever (60) is urged by a cantilever spring (72) into engagement with a battery recess (50). To disengage the latch from the recess, the lever is rotated manually by moving a handle (84) located at another end of the lever. As the battery is being withdrawn, a plunger (90) engages the battery recess to prevent the battery from slipping out. To fully remove the battery, the user forcibly urges the battery out of the compartment. Because the side walls (104) of the plunger are sloped, forcing the battery outward causes the plunger to be depressed, thereby disengaging the plunger from the battery recess.

Abstract: Disclosed is a quick change battery drawer for rapidly substituting a fresh battery for an exhausted battery in the battery drawer of an external, battery powered therapeutic electrical stimulator while the stimulator continues to emit electrical stimulation to treat a patient.

When the release button is depressed, the first and second catches are disengaged, and the bias force acts to eject the battery and battery drawer forcefully into an ejected position where the battery drawer is prevented from completely ejecting from the side opening.
