Abstract

Embodiments provide apparatus, systems, and methods for communicating 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.

First claim

What is claimed is:

1. An analyte data communication apparatus, comprising:
a wireless transmitter/receiver unit configured to be removably docked to an on-body sensor in one configuration and to a management unit in another configuration, the on-body sensor configured to sense data representing a concentration of an analyte present in bodily fluid and having no wireless transmitter/receiver capability, the management unit having no wireless transmitter/receiver capability, wherein the wireless transmitter/receiver unit:
provides the only wireless transmitter/receiver capability in the on-body sensor when docked thereto;
provides the only wireless transmitter/receiver capability in the management unit when docked thereto; and
operates as a transmitter, a receiver, or a stand-alone analyte meter based on a sensed dock connection by the wireless transmitter/receiver unit.

2. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit operates as:
a transmitter based on a sensed connection to the on-body sensor;
a receiver based on a sensed connection to the management unit; and
a stand-alone analyte meter based on a sensed connection to a test sensor.

3. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit comprises a rechargeable battery and receives an electrical charge from the management unit when docked thereto.

4. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit comprises an analyte sensor reader unit configured to receive a test sensor.

5. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit comprises a visual display and is operative to display a measured analyte value.

6. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit comprises a processor, a memory, a transceiver, an antenna, and a rechargeable battery.

7. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit comprises a processor and provides via the processor the only processing capability in the management unit when docked thereto.

8. The apparatus of claim 1 , further comprising the on-body sensor having the wireless transmitter/receiver unit docked thereto, the on-body sensor configured to be connected to a person's body and to be in communication with body fluid of the person, the on-body sensor further configured to transmit analyte data via the wireless transmitter/receiver unit.

9. The apparatus of claim 1 , wherein the wireless transmitter/receiver unit is configured to be received in a sensor pod connected to the on-body sensor.

10. The apparatus of claim 1 , further comprising the management unit having the wireless transmitter/receiver unit docked thereto, the management unit configured to function as a continuous glucose monitor (CGM) receiving a continuous or semi-continuous flow of analyte data via the wireless transmitter/receiver unit.

11. The apparatus of claim 10 , wherein the management unit comprises an analyte sensor reader unit configured to receive a test sensor.

12. An analyte data communication apparatus, comprising:
a wireless transmitter/receiver unit configured to be interchangeably and removably docked to an on-body sensor in a first configuration to transmit a wireless signal, and configured to be interchangeably and removably docked to a management unit in a second configuration to receive a wireless signal, wherein the on-body sensor is configured to sense data representing a concentration of an analyte present in bodily fluid, the management unit has no wireless transmitter/receiver capability, the first and second configurations are based upon a sensed dock connection by the wireless transmitter/receiver unit, and the wireless transmitter/receiver unit provides the only wireless transmitter/receiver capability in the management unit when docked thereto.

13. The apparatus of claim 12 , wherein the wireless transmitter/receiver unit comprises a processor and provides via the processor the only processing capability in the management unit when docked thereto.

14. The apparatus of claim 12 , wherein the wireless transmitter/receiver unit comprises a rechargeable battery and receives an electrical charge from the management unit when docked thereto.

15. The apparatus of claim 12 , wherein the wireless transmitter/receiver unit is configured to operate as a stand-alone analyte meter.

16. The apparatus of claim 12 , wherein the sensed connection is determined via detection of a charge voltage.

17. A communication method for communicating analyte data, comprising:
providing an interchangeable wireless transmitter/receiver unit configurable as either a transmitter or a receiver based on a sensed connection;
configuring the interchangeable wireless transmitter/receiver unit as a transmitter in response to the interchangeable wireless transmitter/receiver unit sensing a connection to an on-body sensor;
transmitting analyte data detected by the on-body sensor from the interchangeable wireless transmitter/receiver unit in response to configuring the interchangeable wireless transmitter/receiver unit as a transmitter;
configuring the interchangeable wireless transmitter/receiver unit as a receiver in response to the interchangeable wireless transmitter/receiver unit sensing a connection to a management unit; and
receiving analyte data at the interchangeable wireless transmitter/receiver unit in response to configuring the interchangeable wireless transmitter/receiver unit as a receiver, the management unit having no wireless transmitter/receiver capability until the interchangeable wireless transmitter/receiver unit is removably docked to the management unit.

18. The method of claim 17 , further comprising reconfiguring the interchangeable wireless transmitter/receiver unit from a transmitter to a receiver in response to sensing a subsequent connection from the on-body sensor to the management unit.

19. The method of claim 17 , further comprising reconfiguring the interchangeable wireless transmitter/receiver unit from a receiver to a transmitter in response to sensing a subsequent connection from the management unit to the on-body sensor.

20. The method of claim 17 , further comprising charging a rechargeable battery of the interchangeable wireless transmitter/receiver unit via an electrical charge received from the management unit in response to sensing the connection to the management unit.
