A METHOD AND A DEVICE FOR DETERMINING A BODY FLUID GLUCOSE LEVEL OF A PATIENT, AND A COMPUTER PROGRAM PRODUCT
First Claim
1. A method for determining a body fluid glucose level of a patient from a continuous signal of a glucose sensor element of a continuous body fluid glucose monitoring device in a data processing unit, comprising:
- receiving measurement data representing a continuous sensor signal provided by a glucose sensor element of a continuous body fluid glucose monitoring device in the data processing unit,receiving calibration data representing a time-dependent zero-signal level of the glucose sensor element in the data processing unit,determining a body fluid glucose level by processing at least the measurement data and the calibration data in the data processing unit, the processing comprising subtraction of the time dependent zero-signal level from the continuous sensor signal, andproviding result data indicative of the continuous body fluid glucose level in the processing unit,wherein the receiving calibration data comprises receiving calibration data representing a time-dependent zero-signal level comprising time-dependent interferent signal contributions representing a presence of an interferent in the body fluid for which the body fluid glucose level is determined, wherein the interferent is a substance different from glucose and the sensor element is responsive to the interferent in the body fluid.
