SYSTEM AND METHOD FOR INFUSION SET DISLODGEMENT DETECTION
First Claim
Patent Images
1. A portable insulin pump, comprising:
- a user interface adapted to display operating information and to receive input data from a user;
a receiver adapted to receive information obtained by a glucose sensor; and
a processor functionally linked to the receiver to receive the information obtained by the glucose sensor and to the user interface to control display of information on the user interface, wherein the processor is configured to;
determine from the information obtained by the glucose sensor whether or not an infusion set connecting the pump to a patient to deliver insulin is or is likely to become dislodged from the patient; and
provide an alert relating to dislodgement of the infusion set from the patient if it is determined from the information obtained by the glucose sensor that the infusion set is or is likely to become dislodged.

Abstract
A portable insulin pump can utilize readings from a sensor incorporated into an infusion set used with the pump to deliver insulin to a patient to determine if the infusion set is or is likely to become dislodged from the patient. Readings from the sensor that are inconsistent with expected readings or a range of expected readings can indicate that the infusion set has become dislodged from the patient.

11. A portable infusion system, comprising:
-
a portable insulin pump including a user interface adapted to display operating information and to receive input data from a user, a receiver and a processor functionally linked to the receiver to receive information from the receiver and to the user interface to control display of information on the user interface; a glucose sensor adapted to obtain information relating to glucose levels of a patient that is received by the portable insulin pump through the receiver; and an infusion set, the infusion set including a cannula adapted to be inserted into the patient, tubing attached to the cannula to transmit insulin delivered with the pump to the cannula and an adhesive patch adapted to retain the infusion set on the patient; and wherein the processor of the insulin pump is adapted to; determine from the information obtained by the glucose sensor whether or not the cannula is or is likely to become dislodged from the patient; and provide an alert on the user interface relating to dislodgement of the cannula from the patient if it is determined from the information obtained by the glucose sensor that the cannula is or is likely to become dislodged. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
