1. An insulin infusion pump system, comprising:
- a portable housing defining a space to receive a supply of insulin;
a pump drive system to dispense medicine from the portable housing when the insulin is received in the space;
control circuitry that electrically communicates with the pump drive system to control dispensation of the medicine according to a programmed dosage schedule from the portable housing when the medicine is received in the space;
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; and
a drop detector configured to respond to an impact to the portable housing, at least a portion of the drop detector being housed in the portable housing, wherein the control circuitry is in electrical communication with the drop detector.

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 portable infusion pump system, comprising:
-
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, the control circuitry being in electrical communication with the pump drive system to control dispensation of medicine according to a programmed dosage schedule from the pump housing when the prefilled medicine cartridge is received in the cavity;
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,a user interface display mounted to the pump housing; and
a drop detector mechanism configured to respond to an impact to the pump housing, the drop detector mechanism being housed in the pump housing and being in electrical communication with the control circuitry. - View Dependent Claims (15, 16, 17, 18, 19)
