1. A method of operating an insulin infusion pump system, comprising:
- controlling dispensation of insulin from a portable pump housing using control circuitry that electrically communicates with a pump drive system in the portable pump housing to selectively output the insulin according to a programmed dosage schedule; and
responding to an impact to the portable pump housing using a drop detector that is at least partially housed in the portable pump housing and that is in electrical communication with the control circuitry, wherein the control circuitry is in electrical communication with the drop detector so that the control circuitry initiates an alarm when the drop detector indicates that the impact to the portable housing is greater than or equal to a predetermined threshold level.

Abstract
Some embodiments of an infusion pump system may be configured to detect when at least one component of the pump system is exposed to an impact above a threshold level. In particular embodiments, the infusion pump system can be equipped with an impact detection system that can sense when an impact above the threshold level has occurred to the pump device, which thereby enables the infusion pump system to initiate appropriate patient safety countermeasures.

14. A method of operating a portable infusion pump system, comprising:
-
controlling dispensation of a medicine according to a programmed dosage schedule from a reusable pump apparatus that houses both a pump drive system and control circuitry within a single pump housing, the pump housing defining a cavity to slidably receive a prefilled medicine cartridge and having user interface display mounted thereto, the control circuitry being in electrical communication with the pump drive system to selectively activate the pump drive system; and respond to an impact to the pump housing using a drop detector mechanism that is housed in the pump housing and that is in electrical communication with the control circuitry, wherein the control circuitry is in electrical communication with the drop detector so that the control circuitry initiates an alarm when the drop detector indicates that the impact to the portable housing is greater than or equal to a predetermined threshold level. - View Dependent Claims (15, 16, 17, 18, 19)
