Ambulatory medical device with electrical isolation from connected peripheral device
First Claim
1. A method of electrically isolating a communication of an ambulatory medical device that is connectable to a peripheral device via an active communication cable, comprising:
- providing an ambulatory medical device having a housing containing a communication connector configured to interface with an active communication cable;
a battery;
a first circuitry comprising a first isolator transceiver, a first GMR isolator transceiver, and a control circuitry; and
a second circuitry comprising a second isolator transceiver, a second GMR isolator transceiver, and a communication circuitry, the ambulatory medical device further having a fluid conduit configured to extend between the housing and the patient, and providing instructions to couple the active communication cable to the communication connector of the medical device and initiate a data transfer between the medical device and the peripheral device such that the first circuitry and the patient are isolated from the second circuitry and the peripheral device while the active communication cable is connected and the data transfer occur at a data transfer rate of at least 12 Mb/second.

Abstract
Methods and apparatus are provided for electrically isolating an ambulatory medical device for infusing treatment materials into a patient when the medical device is connected to a peripheral device via an active communication cable. In one embodiment, the ambulatory medical device includes first circuitry controlling infusion of a medicament to the patient by a fluid conduit connectable to the patient and second circuitry controlling communications when an active communication cable is connected to the medical device. The first and second circuitry are electrically isolated using a pair of first and second isolation transceivers, where the first pair of isolation transceivers communicate a control signal and the second pair of isolation transceivers are giant magneto-resistive (GMR) transceivers that communicate at least one data signal.
