Abstract

A handheld medical device that simultaneously charges its re-chargeable battery and measures one or more characteristics of a bodily fluid is taught. The handheld medical device includes a re-chargeable battery, a wireless power receiver, a battery charging module, and a measurement module. The re-chargeable battery is electrically connected to provide power to components of the handheld medical device. The wireless power receiver outputs power received wirelessly, via an antenna, from a wireless power transmitter that is external to the handheld medical device. The battery charging module selectively charges the re-chargeable battery based on the power received wirelessly from the wireless power transmitter. While the handheld medical device is not connected by wire to any other device, the measurement module measures a characteristic of a sample of a bodily fluid simultaneously with the battery charging module charging the re-chargeable battery.

Claims

1. A handheld medical device that simultaneously charges its re-chargeable battery and measures one or more characteristics of a bodily fluid, the handheld medical device comprising:

a re-chargeable battery that is electrically connected to provide power to components of the handheld medical device;

a wireless power receiver that outputs power received wirelessly, via an antenna, from a wireless power transmitter that is external to the handheld medical device;

a battery charging module that selectively charges the re-chargeable battery based on the power received wirelessly from the wireless power transmitter; and

a measurement module that, while the handheld medical device is not connected by wire to any other device, measures a characteristic of a sample of a bodily fluid simultaneously with the battery charging module charging the re-chargeable battery.

2. The handheld medical device of claim 1 wherein the measurement module measures blood glucose (bG) of the bodily fluid sample simultaneously with the battery charging module charging the re-chargeable battery.

3. The handheld medical device of claim 1 wherein the measurement module measures cholesterol of the bodily fluid sample simultaneously with the battery charging module charging the re-chargeable battery.

4. The handheld medical device of claim 1 wherein the measurement module measures coagulation of the bodily fluid sample simultaneously with the battery charging module charging the re-chargeable battery.

5. The handheld medical device of claim 1 wherein the measurement module measures triglycerides of the bodily fluid sample simultaneously with the battery charging module charging the re-chargeable battery.

6. The handheld medical device of claim 1 further comprising a wireless data transmitter that wirelessly transmits data indicative of the characteristic of the bodily fluid sample to a wireless charging device including the wireless power transmitter.

7. A system comprising:

the handheld medical device of claim 6; and

the wireless charging device,

wherein the wireless charging device transmits the data to a computer via a wire.

8. The handheld medical device of claim 1 further comprising a power supply module that receives the power output by the wireless power receiver, that begins powering the measurement module at a first time after the wireless power receiver begins receiving power wirelessly, and that begins powering one or more components of the handheld medical device other than the measurement module at a second time after the wireless power receiver begins receiving power wirelessly, wherein the second time is after the first time.

9. The handheld medical device of claim 1 wherein the handheld medical device cannot be connected to another device or an external power source by wire.

10. A system for monitoring one or more characteristics of a bodily fluid, the system comprising:

a wireless power transmitter that is integrated within a wireless charging device, that receives power via a wire that is connected between the wireless charging device and an external power source, and that wirelessly outputs power; and

a handheld medical device comprising;

a re-chargeable battery that is electrically connected to provide power to components of the handheld medical device;

a wireless power receiver that outputs power received wirelessly, via an antenna, from a wireless power transmitter that is external to the handheld medical device;

a battery charging module that selectively charges the re-chargeable battery based on the power received wirelessly from the wireless power transmitter; and

a measurement module that, while the handheld medical device is not connected by wire to any other device, measures a characteristic of a sample of a bodily fluid simultaneously with the battery charging module charging the re-chargeable battery.

11. The system of claim 10 wherein the wire that is configured in accordance with a universal serial bus (USB) standard.

12. The system of claim 10 wherein the wireless power transmitter wirelessly outputs and the wireless power receiver wirelessly receives radio frequency (RF) power.

14. The system of claim 10 wherein the wireless power transmitter and the wireless power receiver are capacitively coupled.

15. The system of claim 10 further comprising a wireless data transceiver that is integrated within the wireless charging device,

wherein handheld medical device further comprises a wireless data transmitter that wirelessly transmits data indicative of the characteristic of the sample to the wireless data transceiver.

16. The system of claim 15 wherein the wireless data transceiver transmits the data to a computer over the wire.

17. The system of claim 10 wherein the wireless charging device further comprises a holding member for maintaining a predetermined spatial relationship between the handheld medical device and the wireless charging device.

18. The system of claim 10 wherein the handheld medical device further comprises a second holding member for maintaining the predetermined spatial relationship between the handheld medical device and the wireless charging device.

19. The system of claim 17 wherein at least one of the holding member and the second holding member includes a magnetic member.

20. A method for simultaneously wirelessly transmitting power to a handheld medical device and operating the handheld medical device, the method comprising:

wirelessly transmitting power to the handheld medical device using an antenna of a wireless charging device;

receiving power wirelessly, using an antenna of the handheld medical device, from the wireless charging device; and

simultaneously with the wireless receipt of power from the wireless charging device, measuring, using the handheld medical device, a characteristic of a sample of a bodily fluid while the handheld medical device is not connected by wire to any other device.

21. A system for monitoring one or more characteristics of a bodily fluid, the system comprising:

a wireless charging device that comprises;

a wireless power transmitter that receives power via a wire that is connected between the wireless charging device and an external power source and that wirelessly outputs power via an antenna;
