Abstract
Methods and systems for providing data communication in medical systems are disclosed.
Claims21
An analyte monitoring device, comprising:
- a counter;
- and
- a data processing section coupled to the counter, wherein the data processing section is configured to:
- establish a communication range between the analyte monitoring device and a remote device when the remote device is placed within a predetermined distance from the analyte monitoring device;
- determine when a transcutaneously positioned analyte sensor is initialized;
- increment a count stored in the counter based on the determination;
- associate the incremented count with the transcutaneously positioned analyte sensor;
- and
- transmit, using a communication module, the incremented count to the remote device when the remote device is placed within the established communication range, wherein the incremented count is used to verify the identity of the new transcutaneously positioned analyte sensor.
6 more elements
A control device for communicating with an analyte monitoring unit, comprising:
- a data communication section configured to establish a communication range with the analyte monitoring unit when the control unit is placed within a predetermined distance from the analyte monitoring unit and further configured to receive data, including a count information associated with a transcutaneously positioned analyte sensor, when the control device is placed within the established communication range;
- and
- a processing unit coupled to the data communication section to process the received data, the processing unit further configured to compare the count information in the received data with a stored count to verify the identity of the transcutaneously positioned analyte sensor, and when it is determined that the received count information is different than the stored count, the processing unit is configured to generate one or more signals related to the status of the transcutaneously positioned analyte sensor including the identity of the transcutaneously positioned analyte sensor.
A method, comprising:
- establishing a communication range between an analyte monitoring device and a remote device when the remote device is placed within a predetermined distance from the analyte monitoring device;
- detecting an initialization of a transcutaneously positioned analyte sensor;
- associating a count with the transcutaneously positioned analyte sensor;
- transmitting the count associated with the transcutaneously positioned analyte sensor to the remote device when the remote device is placed within the established communication range, wherein the count is used to verify the identity of the transcutaneously positioned analyte sensor;
- detecting replacement of the transcutaneously positioned analyte sensor;
- updating the count based on the detected replacement;
- and
- transmitting the updated count to the remote device when the remote device is placed within the established communication range.
5 more elements
A method, comprising:
- establishing a communication range between an analyte monitoring device and a remote device when the remote device is placed within a predetermined distance from the analyte monitoring device;
- receiving data including a count information associated with a transcutaneously positioned analyte sensor from the analyte monitoring device when the remote device is placed within the established communication range;
- comparing the received count information with a stored count information to verify the identity of the transcutaneously positioned analyte sensor;
- and
- generating one or more signals related to the status of the transcutaneously positioned analyte sensor including the identity of the transcutaneously positioned analyte sensor when it is determined that the count information of the received data is different than the stored count information.
