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 a moisture level above a threshold level. In particular embodiments, the infusion pump system can be equipped with a moisture level detection system that can sense when a moisture level above the threshold level has occurred to the pump device, which thereby enables the infusion pump system to initiate one or more patient safety countermeasures.
Claims21
-20. (canceled)
A medical infusion pump system, comprising:
- a portable housing defining a space to receive a medicine;
- a pump drive system to dispense medicine from the portable housing when the medicine 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
- hydrophilic foam material positioned in the portable housing and in electrical communication with the control circuitry, the control circuitry being adapted to detect the absorption of moisture into the hydrophilic foam material.
A method of controlling a portable infusion pump system, comprising:
- sensing that a hydrophilic foam material positioned in a portable infusion pump system has a change in an electrical resistance;
- and
- in response to the sensing that the change in an electrical resistance exceeds a threshold, disabling a pump drive system housed in the portable infusion pump system.
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 hydrophilic foam material positioned in 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, the control circuitry being adapted to detect the absorption of moisture into the hydrophilic foam material.
