Abstract

A diabetes care system for detection of an analyte and method for selective data transmission are disclosed. The diabetes care system has a mobile component and a base station, wherein a data transmission occurring between the mobile component and the base station within a time interval in which a wireless communication link exists, wherein is selectively performed in such a manner that within the time interval, a first partial set of the data is transmitted from the mobile component to the base station. The first partial set is selected using a processor-controlled selection algorithm in such a manner that the data transmitted in the time interval is representative of the entirety of the data stored in the mobile component.

Claims

1. A diabetes care system for use on a person, comprising:

a base station having a communication unit for wirelessly receiving data, a memory unit for storing transmitted data, and optionally an output unit for displaying the transmitted data; and

a mobile component configured to be carried by the person and including, a continuous measurement unit implantable in the person for measuring relevant data for treatment of diabetes mellitus, a memory for storing the measured data for the treatment of diabetes mellitus, a communication unit for wirelessly transmitting the measured data for treatment of diabetes mellitus to the base station, and a processor programmed to control a selection algorithm, and cooperatively operable with the communication unit to selectively perform a data transmission in such a manner that within a first time interval, in which a wireless communication link between the mobile component and the base station exists, a first partial set, selected from all of the measured data for treatment of diabetes mellitus stored in the memory of the mobile component, is transmitted from the mobile component to the base station, and the first partial set is selected using the processor-controlled selection algorithm,

wherein the selection algorithm selects a subset of the measured data for treatment of diabetes mellitus using a variable time raster without analyzing all of the measured data for treatment of diabetes mellitus stored in the mobile component, identifies one or more outlier values in the subset of data which lie outside a predefined and changeable tolerance band and further selects data from the subset of measured data within a time interval around each of the outlier values using a constant time raster, such that the first partial data set includes the further selected data.

2. The diabetes care system according to claim 1, wherein the processor of the mobile component is programmed such that the first partial set of the data is selected before beginning the data transmission.

3. The diabetes care system according to claim 1, wherein the processor of the mobile component is programmed such that at least a part of the first partial set of the data is transmitted to the base station in a sequence which is reversed from the sequence of its generation.

4. The diabetes care system according to claim 1, wherein an alarm unit is provided as part of the base station to output an optical and/or acoustic warning message if the number of transmitted items of data falls below a lower limit.

5. The diabetes care system according to claim 1, wherein a number of data of the first partial set which have been transmitted by the mobile component to the base station is registered in the mobile component and/or in the base station.

6. The diabetes care system according to claim 1, wherein the processor of the mobile component is programmed such that transmitted data are erased from the memory of the mobile component.

7. The diabetes care system according to claim 1, wherein the mobile component is wearable in order to be carried by the person.

8. A method for selective data transmission within a diabetes care system, comprising:

providing a diabetes care system for use on a person, which comprises

a base station having a communication unit for wirelessly receiving data, a memory unit for storing transmitted data, and optionally an output unit for displaying the transmitted data, and

a mobile component configured to be carried by the person and including a continuous measurement unit implantable in the person for measuring relevant data for treatment of diabetes mellitus, a memory for storing the measured data for treatment of diabetes mellitus, a communication unit for wirelessly transmitting the measured data for treatment of diabetes mellitus to the base station, and a processor being programmed to control a selection algorithm, and cooperatively operates with the a communication unit to

selectively perform a data transmission in such a manner that within a first time interval, in which a wireless communication link between the mobile component and the base station exists, a first partial set, selected from all of the measured data for treatment of diabetes mellitus stored in the memory of the mobile component, is transmitted from the mobile component to the base station, and the first partial set is selected using the processor-controlled selection algorithm;

selecting a first partial set of the measured data for treatment of diabetes mellitus by means of the processor-controlled selection algorithm, using a variable time raster without analyzing all of the measured data for treatment of diabetes mellitus stored in the mobile component,

identifying one or more outlier values in the subset of data which lie outside a predefined and changeable tolerance band and

further selecting data from the subset of data within a time interval around each of the outlier values using a constant time raster, such that the first partial data set includes the further selected data; and

transmitting the first partial set of the data from the mobile component to the base station within the first time interval.
