Abstract

A blood glucose measuring system which comprises a blood glucose (bG) meter and a portable communication device (PCD) and methods thereof are disclosed. The blood glucose meter comprises a measurement module and a wireless module, wherein the measurement module is operable to measure the blood glucose level of a blood sample, the wireless module is an embeddable module and communicates to the measurement module via a serial interface, and the wireless module is operable to wirelessly communicate to the portable communication device. The portable communication device is operable to wirelessly receive information from the blood glucose meter related to the blood glucose measurement.

Claims

1. A blood glucose measuring system comprising a blood glucose (bG) meter and a portable communication device (PCD), wherein:

the blood glucose meter comprises a measurement module and a wireless module, wherein;

the measurement module measures the blood glucose level of a blood sample;

the wireless module is an embeddable module and communicates to the measurement module via a serial interface and wirelessly to the portable communication device; and

the portable communication device receives information from the blood glucose meter related to the blood glucose measurement.

2. The system of claim 1 wherein the wireless communication is Bluetooth, Zigbee, or infrared light.

3. The system of claim 1 wherein the PCD is a cellular phone, a smart phone, or a personal digital assistant.

4. The system of claim 1 wherein the measurement module comprises a measurement controller, user switches, a measurement application-specific integrated circuit (ASIC), a display, a serial interface to the communication module, and a battery.

5. The system of claim 4 wherein the measurement ASIC receives a measurement strip and determines the blood glucose level of a blood sample placed on the measurement strip.

6. The system of claim 1 wherein the communication module comprises a communication controller, a communication transceiver, an antenna, a voltage regulator, and an interface to the measurement module.

7. A method for establishing wireless communication between a blood glucose (bG) meter and a portable communication device (PCD), wherein the bG meter comprises a measurement module and a wireless module, wherein the measurement module measures the blood glucose level of a blood sample, and the wireless module is an embeddable module and communicates to the measurement module via a serial interface, the method comprising:

switching on power to the bG meter and the PCD;

sending a pairing beacon by the bG meter to the PCD, wherein the pairing beacon comprises information related to a type of the bG meter and a serial number of the bG meter;

receiving the pairing beacon by the PCD;

determining whether the PCD will establish wireless communication to the bG meter based on the type and the serial number of the bG meter;

sending a response to the pairing beacon by the PCD to the bG meter indicating whether the PCD will establish wireless communication to the bG meter; and

indicating on the bG meter whether the wireless communication was established.

8. The method of claim 7 wherein the sending of the pairing beacon and the sending of the response to the pairing beacon are performed by way of Bluetooth, Zigbee, or infrared light.

9. The method of claim 7 wherein the PCD is one of a cellular phone, a smart phone, and a personal digital assistant.

10. The method of claim 7 wherein the measurement module comprises a measurement controller, user switches, a measurement application-specific integrated circuit (ASIC), a display, a serial interface to the communication module, and a battery.

11. The method of claim 10 further comprising determining the blood glucose level of a blood sample by providing a measurement strip to the measurement ASIC and providing the blood sample to the measurement strip.

12. The method of claim 7 wherein the communication module comprises a communication controller, a communication transceiver, an antenna, a voltage regulator, and an interface to the measurement module.

13. A method for wirelessly communicating a result of a blood glucose measurement between a blood glucose (bG) meter and a portable communication device (PCD), wherein the bG meter comprises a measurement module and a wireless module, wherein the measurement module measures the blood glucose level of a blood sample, and the wireless module is an embeddable module and communicates to the measurement module via a serial interface, the method comprising:

inserting a measurement strip into the bG meter, wherein the measurement strip has a sample of the blood to be measured;

measuring the bG level of the blood sample by the measurement module of the bG meter;

serially sending a result of the bG level measurement by the measurement module to the wireless module;

wirelessly sending the result of the measurement by wireless module of the bG meter to the PCD; and

displaying the result of the measurement on the PCD.

14. The method of claim 13 wherein the sending of the pairing beacon and the sending of the response to the pairing beacon are performed by way of Bluetooth, Zigbee, or infrared light.

15. The method of claim 13 wherein the PCD is selected from a cellular phone, a smart phone, and a personal digital assistant.

16. The method of claim 13 wherein the measurement module comprises a measurement controller, user switches, a measurement application-specific integrated circuit (ASIC), a display, a serial interface to the communication module, and a battery.

17. The method of claim 16 wherein the measurement ASIC determines the blood glucose level of the blood sample from the measurement strip inserted into the bG meter.

18. The method of claim 13 wherein the communication module comprises a communication controller, a communication transceiver, an antenna, a voltage regulator, and an interface to the measurement module.
