Abstract:
1. A portable infusion pump system, comprising: a pump device including a pump housing that defines a space to receive a medicine, a drive system positioned in the pump housing to dispense the medicine from the pump device when the medicine is received in the space of the pump housing, and a drop detection mechanism mechanically mounted to a component of the pump housing, wherein the drop detection mechanism shifts from a first configuration to a second configuration in response to an impact on the pump housing that is greater than or equal to a predetermined threshold level; wherein the drop detection mechanism comprises a weighted member suspended in a spaced from one or more electrically conductive wires coupled to a circuit, wherein the drop detector mechanism shifts from the first configuration to the second configuration when at least one of the wires is broken; and a controller device removably attachable to the pump housing so as to electrically connect with the pump device, wherein the controller device houses control circuitry configured to communicate with the drive system positioned in the pump housing to control dispensation of the medicine from the pump device.
