1. A device for remotely controlling 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;
a display disposed on the housing;
a processor disposed within the 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 chipo and the data to the data isolation integrated circuit chip; and
wherein the housing and electrical connector port provide a seal preventing passage of moisture into the internal cavity.

Abstract
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.
