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.

Claims

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 from the portable housing when the medicine is received in the space; 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.
