Patent ID: 8552880

Claim:
An ambulatory infusion pump assembly for delivering a fluid from a fluid reservoir to an infusion set adapted for the subcantaneous infusion of the fluid into the body of a patient, the operation of said pump assembly presenting at least one measurable pump assembly operating parameter having a predetermined normal operating value, the pump assembly, comprising: a pump mechanism; an upstream delivery line operably coupling the pump mechanism to said fluid reservoir in fluid conveying relationship; a downstream delivery tube operably coupling the pump mechanism to said infusion set in fluid conveying relationship; a control system configured to control operation of the pump assembly; at least one sensor operably coupled with said control system, the sensor adapted for sensing the value of said at least one pump assembly operating parameter of said pump assembly; a user interface including a display and a control pad operably coupled to the control system and adapted for interactive operation of said pump assembly; the control system further including a guided user help system configured to present an alarm when said at least one sensor senses the value of said at least one pump assembly operating parameter to be outside of said predetermined normal operating value, and to present on the display a control system guided procedure, adapted to correct said at least one operating parameter back to said predetermined normal operating value.
