INFUSION PUMP APPARATUS, METHOD AND SYSTEM
First Claim
1. An infusion pump system comprising:
- a syringe having a plunger movable within the syringe barrel, the syringe having an exit end;
at least one temperature determination device adjacent to the syringe;
at least one device to determine the distance the plunger has moved with respect to the syringe barrel; and
a pump processor in communication with the at least one temperature determination device and the at least one optical sensor,wherein when the controller determines a change in temperature and a corresponding plunger movement, the controller increases or decreases a preprogrammed basal rate of the infusion pump by a predetermined amount for a predetermined time.
