Abstract

A replaceable, stand-alone charging apparatus for insertion into a portable electronic device having an energy storage device and a rechargeable battery that supplies energy to the energy storage device is provided. The replaceable, stand-alone charging apparatus has a body and a battery charging device housed substantially with the body and operable to charge the rechargeable battery of the portable electrical device. The replaceable, stand-alone charging apparatus further has an electrical connector adapted for connection with a cooperative electrical connector coupled to the rechargeable battery of the portable electronic device. The electrical connector is in electrical communication with the battery charging device.

Claims

1. A portable electronic medical device for use with electrodes, comprising:

a housing with a well formed thereon;

an energy storage device in the housing for storing energy that can be transferred to the electrodes; and

a rechargeable power source in the housing for storing energy that can be transferred to the energy storage device,

in which the well is configured to receive a selectively removable portable standalone charging apparatus including a charging device, and

if the selectively removable portable standalone charging apparatus is inserted into the well, the charging device is operable to recharge the power source.

2. The medical device of claim 1, further comprising:

an electrical connector adapted for connection with a cooperative electrical connector of the charging apparatus for the recharging.

3. The medical device of claim 1, in which

the well has a generally triangular cross-section.

4. The medical device of claim 1, in which

a latch is operable to secure the portable standalone charging apparatus in the well.

5. The medical device of claim 4, in which

the latch is movable between an extended position and a retracted position,

the latch biased towards the extended position, and

partial insertion of the charging apparatus into the well causes the latch to move to the retracted position, the latch returning to the extended position after the charging apparatus is fully inserted into the well.

6. The medical device of claim 5, further comprising:

a biasing member, and

in which when the latch is moved to the retracted position, the biasing member exerts a force for ejecting the charging apparatus from the well.

7. The medical device of claim 1, in which

the energy storage device in the housing comprises at least one capacitor.

8. A portable, stand-alone charging apparatus for insertion into a well of a portable electronic medical device, the medical device including an energy storage device for storing energy for use by electrodes, and a rechargeable power source for storing energy for use by the energy storage device, the charging apparatus comprising:

a body configured to be inserted within the well; and

a charging device housed substantially within the body and operable to recharge the power source when the body has been inserted into the well.

9. The apparatus of claim 8, further comprising:

an electrical connector adapted for connection with a cooperative electrical connector of the portable electronic device for the recharging.

10. The apparatus of claim 8, in which

the body has a generally triangular cross-section.

11. The apparatus of claim 8, in which

a latch is operable to secure the body in the well.

12. The apparatus of claim 11, in which

the latch is movable between an extended position and a retracted position,

the latch biased towards the extended position, and

partial insertion of the body into the well causes the latch to move to the retracted position, the latch returning to the extended position after the body is fully inserted into the well.

13. The apparatus of claim 12, in which

the latch includes a latch member that protrudes from the body when the latch is in the extended position, but does not protrude from the body when the latch is in the retracted position.

14. The apparatus of claim 8, in which

the energy storage device comprises at least one capacitor.

15. An assembly comprising:

a portable electronic medical device for use with electrodes, the portable electronic medical device comprising;

a housing with a well formed thereon,

an energy storage device in the housing for storing energy that can be transferred to the electrodes, and

a rechargeable power source in the housing for storing energy that can be transferred to the energy storage device; and

a selectively removable portable standalone charging apparatus including a charging device inserted into the well, wherein the charging device is operable to recharge the power source.

16. The assembly of claim 15, in which

the portable electronic medical device includes an electrical connector adapted for connection with a cooperative electrical connector of the charging apparatus for the recharging.

17. The assembly of claim 15, in which

the well has a generally triangular cross-section.

18. The assembly of claim 15, in which

a latch is operable to secure the portable standalone charging apparatus in the well.

19. The assembly of claim 18, in which

the latch is movable between an extended position and a retracted position,

the latch biased towards the extended position, and

partial insertion of the charging apparatus into the well causes the latch to move to the retracted position, the latch returning to the extended position after the charging apparatus is fully inserted into the well.

20. The assembly of claim 19, in which

the portable electronic medical device includes a biasing member, and

when the latch is moved to the retracted position, the biasing member exerts a force for ejecting the charging apparatus from the well.

21. The assembly of claim 15, in which

the energy storage device in the housing comprises at least one capacitor.
