Abstract
Disclosed are methods and apparatuses for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment dose (e.g. insulin, dextrose, etc.) and provide glycemic control. The dose of the treatment drug may be based on the patient'"'"'s calculated sensitivity to treatment dosing, for example. The dose of the treatment drug may be based on the concentration of the analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte. Delivery of the treatment drug can be cut off if the determined analyte concentration indicates that continued delivery would be harmful to the patient.

26. An infusion control system, comprising:
-
an external infusion pump configured to infuse an infusion fluid into a patient, the external infusion pump comprising a memory containing an identity of the infusion fluid; and a patient monitoring device configured to measure the concentration of an analyte in a sample of bodily fluid drawn from the patient, the patient monitoring device comprising a communication interface providing a communication link to the external infusion pump, the communication interface configured to query the external infusion pump and to receive the identity of the infusion fluid, and the patient monitoring system is configured to determine whether the infusion fluid affects the concentration of the analyte. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)

101. A method of controlling a concentration of glucose in a body fluid of a patient, the method comprising:
-
infusing insulin into the patient using an infusion pump; accessing the body fluid of the patient using an analyte detection system that is separate from and spaced apart from the infusion pump; measuring a concentration of glucose in the body fluid of the patient using the analyte detection system; communicating information related to the concentration of glucose from the analyte detection system to the infusion pump using a wireless communication interface; automatically stopping the infusion of insulin by the infusion pump in response to a determination that the concentration of glucose in the body fluid is below a threshold; permitting the patient'"'"'s glucose concentration to coast for a time uninfluenced by further infusion of insulin; and automatically restarting the infusion of insulin using the infusion pump. - View Dependent Claims (102, 103, 104, 105)
