Power management techniques for an infusion pump system

摘要

Some embodiments of an infusion pump system can employ a number of power management techniques to avoid using substantially excessive power during operation of the pump drive system. Thus, the infusion pump system can draw upon the energy supply in an efficient manner that extends the useful life on the power supply. Furthermore, the infusion pump system can be configured estimate an amount of power remaining to operate the pump system without the requirement of directly detecting the remaining charge on power supply device (e.g., without detecting the remaining charge on a battery). As such, the infusion pump system can readily inform a user of a particular estimated amount of time remaining for medicine dispensing operations.

主权项

1. A wearable infusion pump system, comprising:
a pump device including a drive system to dispense medicine from the pump device, the drive system defining an energy requirement profile to perform a medicine dispensing operation, wherein the energy requirement profile includes a gradual increase in the amount of energy delivered to the drive system during the medicine dispensing operation; a memory for storing the energy requirement profile of the drive system; an energy storage source to deliver electrical energy to the drive system; and a controller device configured to access the memory for retrieving the energy requirement profile and to initiate the medicine dispensing operation by supplying a pattern of voltage pulses from the energy storage source to the drive system, the pattern of voltage pulses being correlated to the energy requirement profile of the drive system.
