Sterile battery charging device
A sterile battery charging device and assembly for charging within a sterile field. The battery charging assembly includes a base unit having a first interface and a second interface. The assembly additionally includes a high capacity battery connectable to the first interface and a low capacity battery connectable to the second interface. The base unit retrieves power from the high capacity battery and transmits power to the low capacity battery. The high capacity battery and the low capacity battery are interchangeably connectable to the base unit.
1. A battery charging device, comprising:
a number of base units each having a first interface and a second interface, the first interface configured to receive a first battery and the second interface configured to receive a second battery;
a first of the number of the base units is configured to retrieves power from the first battery wherein when the first battery is attached to a second of the number of the base units and transmits power to the second battery wherein when the second battery is attached to the first of the number of the base units; and
both the first and second interfaces of each of the number of base units are located on a position where the first battery and the second battery are interchangeably attachable.
2. The device of claim 1 , wherein the base unit is substantially planar.
3. The device of claim 1 , wherein the base unit is substantially rectangular.
4. The device of claim 1 , wherein the first interface is a pair of spaced and substantially parallel rails extending along each of the number of base units.
5. The device of claim 4 , wherein the first battery is slidable within the pair of spaced and substantially parallel rails.
6. The device of claim 1 , wherein the second interface is one or more battery contacts.
7. The device of claim 1 , wherein the first and second batteries are sterilizable.
8. A battery charging assembly, comprising:
a number of base units each having a first interface and a second interface;
