Abstract

A multiple power-source housing adapted to prevent simultaneous removal of more than a single power source, such as a battery, at a time. In an example embodiment, the power-source housing is used to house batteries for an intra-aortic balloon pump, which use battery power during transport. The power-source housing holds a first and second power source. When the first power source is removed, a mechanism, such as a knob, prevents simultaneous removal of the second power source or removal of the second power source until the first power source is replaced. Similarly, when the second power source is removed the mechanism prevents simultaneous removal of the first power source or removal of the first power source until the second power source is replaced.
