Abstract

Embodiments provide apparatus, systems, and methods adapted to communicate analyte data and/or related information. In a first aspect, the apparatus includes a transmitter/receiver unit which is configurable as either a transmitter or a receiver. The transmitter/receiver unit may be coupled to an on-body sensor and may be configured as a transmitter, or may be coupled to a management unit and may be configured as a receiver as part of a continuous analyte monitoring system. Analyte data communication systems and methods are provided, as are other aspects.

Claims

1. An analyte data communication system, comprising:

an on-body sensor for continuous glucose monitoring including an in vivo sensor component and a first wireless transmitter/receiver unit dock, the on-body sensor coupleable to a user via a wearable adhesive patch;

a management unit including a processor, a user interface for displaying analyte data from the on-body sensor, and a second wireless transmitter/receiver unit dock; and

a plurality of wireless transmitter/receiver units each adapted to be removably docked into both the first wireless transmitter/receiver unit dock of the on-body sensor and the second wireless transmitter/receiver unit dock of the management unit, and each wireless transmitter/receiver unit being operable to be paired for communication with each other;

wherein;

a first of the plurality of wireless transmitter/receiver units is further adapted to transmit a wireless signal when docked in the first wireless transmitter/receiver unit dock of the on-body sensor to a second of the plurality of wireless transmitter/receiver units docked in the second wireless transmitter/receiver unit dock of the management unit, and to receive an electrical recharge from the management unit when docked in the second wireless transmitter/receiver unit dock of the management unit,

the wireless transmitter/receiver units are automatically reconfigurable to transmit analyte data from the on-body sensor to another paired wireless transmitter/receiver unit in response to a sensed connection with the on-body sensor and to receive analyte data from the on-body sensor from another paired wireless transmitter/receiver unit in response to a sensed connection with the management unit, and

the management unit has no wireless transmitter/receiver capability unless one of the plurality of wireless transmitter/receiver units is removably docked into the second wireless transmitter/receiver unit dock.

2. The system of claim 1, wherein the first wireless transmitter/receiver unit dock comprises a sensor pod.

3. The system of claim 1, wherein the wireless transmitter/receiver units are physically interchangeable.

4. The system of claim 1, wherein the wireless transmitter/receiver units are adapted to be charged by a power supply of the management unit when the wireless transmitter/receiver units are connected to the management unit.

5. The system of claim 1, wherein the second wireless transmitter/receiver unit dock comprises a recessed holder located in a housing of the management unit.

6. The system of claim 1, further comprising an analyte sensor reader unit integrated into the management unit.

7. The system of claim 1, further comprising an analyte sensor reader unit integrated into the wireless transmitter/receiver units.

8. The system of claim 1, further comprising a processor in each of the wireless transmitter/receiver units, wherein the processor of a transmitter/receiver unit coupled to the management unit comprises the only processor for the management unit.

9. The system of claim 1, wherein the wireless transmitter/receiver units are operable as stand-alone analyte meters.

10. A communication method for communicating analyte data, comprising:

providing a plurality of interchangeable wireless transmitter/receiver units, each configurable as either a transmitter or a receiver based on a sensed connection and each unit operable to be docked into both an on-body sensor and a management unit, wherein the on-body sensor is coupleable to a user via a wearable adhesive patch;

transmitting analyte data from a first interchangeable wireless transmitter/receiver unit removably docked into the on-body sensor to a second interchangeable transmitter/receiver unit removably docked into the management unit, the management unit having no wireless transmitter/receiver capability unless one of the plurality of interchangeable wireless transmitter/receiver units is removably docked into the management unit;

receiving the analyte data at the second interchangeable transmitter/receiver unit removably docked into the management unit from the first interchangeable wireless transmitter/receiver unit removably docked into the on-body sensor;

receiving at the second interchangeable transmitter/receiver unit an electrical recharge from the management unit;

automatically reconfiguring the first wireless transmitter/receiver unit to receive the analyte data from the second wireless transmitter/receiver unit upon the first wireless transmitter/receiver unit being docked into the management unit; and

automatically reconfiguring the second wireless transmitter/receiver unit to transmit analyte data to the first wireless transmitter/receiver unit upon the second wireless transmitter/receiver unit being docked into the on-body sensor.

11. The method of claim 10, further comprising configuring the first interchangeable wireless transmitter/receiver unit as a transmitter.

12. The method of claim 11, wherein the configuring is based upon whether the on-body sensor is detected.

13. The method of claim 10, further comprising configuring the second interchangeable wireless transmitter/receiver unit as a receiver.

14. The method of claim 13, wherein the configuring is based upon whether a charge voltage is detected.

15. The method of claim 10, wherein the first interchangeable wireless transmitter/receiver unit and second interchangeable wireless transmitter/receiver unit include identical components.

16. The method of claim 10, further comprising detachably receiving the first interchangeable wireless transmitter/receiver unit in a sensor pod coupled to the on-body sensor.

17. The method of claim 10, further comprising detachably receiving the second interchangeable wireless transmitter/receiver unit on a management unit.

18. The method of claim 10, further comprising configuring the first interchangeable wireless transmitter/receiver and the second interchangeable wireless transmitter/receiver unit based upon whether a charge voltage exists or whether the on-body sensor is detected.

19. The method of claim 10, further comprising displaying an analyte measurement value on the first interchangeable wireless transmitter/receiver unit, the second interchangeable wireless transmitter/receiver unit or both.
