Infusion Pump System and Method

摘要

Some embodiments of an infusion pump system may be configured to provide a desired level of resistance to liquid ingress to the pump casing while contemporaneously providing air transmissibility for equalization of air pressure differentials between the interior and exterior of the pump casing. Further, some embodiments can detect when moisture inside a casing of the infusion pump system is greater than or equal to a threshold level and can initiate one or more patient safety countermeasures.

主权项

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 structure positioned in the pump housing that defines an open airflow passageway so dimensioned to inhibit ingress of liquid to an interior of the pump housing and provide air pressure equilibrium between an exterior of the pump housing and the interior of the pump housing; 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.
