A portable medical device includes an interface for accepting a power supply and enabling data transfer while still connected to a human body. The interface may include a universal serial bus interface and may be coupled to a data isolation chip and a power isolation chip. A power controlling processor may determine how the supplied power, e.g., voltage, is supplied to other components within the infusion device. Additional circuitry within the system may provide a secure power transfer within the device to ensure user safety and ensure that a high frequency noise is properly attenuated.

1. An ambulatory infusion pump, comprising: a housing having a front surface and a back surface that are spaced apart and enclosed by side surfaces to define an internal cavity;an electrical connector port fitted to the housing and extending into the internal cavity, the electrical connector port operably connected to a power isolation integrated circuit chip and a data isolation integrated circuit chip disposed within the housing, the electrical connector port adapted to receive electrical power and data via a direct electrical connection, and direct the electrical power to the power isolation integrated circuit chip and the data to the data isolation integrated circuit chip; andwherein the housing and electrical connector port provide a seal preventing passage of moisture into the internal cavity. 2. The ambulatory infusion pump of claim 1, further comprising an electrical connector port door configured to be attached to the housing over the electrical connector port. 3. The ambulatory infusion pump of claim 2, wherein a seal is formed between the electrical connector port and the electrical connector port door. 4. The ambulatory infusion pump of claim 3, further comprising an overmold formed around the power isolation integrated circuit chip and in contact with the electrical connector port that provides the seal between the electrical connector port and the electrical connector port door. 5. The ambulatory infusion pump of claim 4, wherein the overmold is comprised of a non-conductive material. 6. The ambulatory infusion pump of claim 1, wherein the power isolation integrated circuit chip is electrically isolated from the data isolation integrated circuit chip. 7. The ambulatory infusion pump of claim 1, further comprising: a processor disposed in the housing; anda touch sensitive display screen, wherein the processor is capable of receiving inputs from the touch sensitive display screen. 8. The ambulatory infusion pump of claim 1, wherein the power isolation integrated circuit chip is coupled to a power isolation circuit, and wherein the power isolation circuit includes a transformer capable of outputting a substantially constant output. 9. The ambulatory infusion pump of claim 8, further comprising a battery charger configured to receive the substantially constant output from the transformer. 10. The ambulatory infusion pump of claim 1, wherein the seal is provided by an o-ring between the electrical connector port and the housing. 11. An ambulatory infusion pump, comprising: a housing define an enclosed internal cavity;an electrical connector port fitted to the housing and extending into the internal cavity, the electrical connector port including an opening adapted to receive electrical power and data through a common direct electrical connection;a power isolation integrated circuit chip operably connected to the electrical connector port to receive the electrical power;a data isolation integrated circuit chip operably connected to the electrical connector port to receive the data; andan overmold disposed within the housing, the overmold enclosing the electrical connector port, the power isolation integrated circuit chip , and the data isolation integrated circuit chip, to electrically isolate the electrical connector port, the power isolation integrated circuit chip, and the data isolation integrated circuit chip from the internal cavity of the housing. 12. The ambulatory infusion pump of claim 11, wherein the electrical connector port opening is exteriorly exposed on the housing, and further comprising an electrical connector port door configured to be attached to the housing over the electrical connector port. 13. The ambulatory infusion pump of claim 12, further comprising an o-ring providing a seal between the housing and the electrical connector port door. 14. The ambulatory infusion pump of claim 13, further comprising an o-ring providing a seal between the electrical connector port and the housing. 15. The ambulatory infusion pump of claim 11, wherein the overmold is comprised of a non-conductive material. 16. The ambulatory infusion pump of claim 11, wherein the power isolation integrated circuit chip is electrically isolated from the data isolation integrated circuit chip. 17. The ambulatory infusion pump of claim 11, further comprising a transformer disposed within the overmold and configured to control electrical input from the electrical connector port. 18. The ambulatory infusion pump of claim 17, further comprising a battery charger configured to receive substantially constant output from the transformer. 19. The ambulatory infusion pump of claim 11, further comprising: a processor disposed in the housing; anda touch sensitive display screen, wherein the processor is capable of receiving inputs from the touch sensitive display screen.
