Abstract

A method for connecting wireless devices using Bluetooth® low energy can be used to connect wireless computing devices with a medical device in an ambulatory care setting. The wireless computing devices can receive measured vital sign data and transmit the vital sign data to a patient'"'"'s electronic medical record. The wireless computing devices can be configured to include a user-friendly name and the transmitter power in one or more advertising broadcasts. The medical device can receive advertising broadcasts from one or more wireless computing devices and sort the devices by proximity, last use, number of times used, or alphabetically. After the devices exchange information over Bluetooth® low energy, the devices can connect in Bluetooth® Classic. Systems for implementing the method are also disclosed.

Claims

1. A method for connecting with a wireless device, comprising:

receiving, at a host computing device, a Bluetooth®

low-energy broadcast from one or more wireless devices that are in a range of the host computing device;

identifying the one or more wireless devices;

sorting the one or more wireless devices;

displaying a name for each of the one or more wireless devices; and

connecting to one of the one or more wireless devices.

2. The method for connecting with a wireless device of claim 1, further comprising receiving a transmitter power from at least one of the one or more wireless devices.

3. The method for connecting with a wireless device of claim 2, wherein the one or more wireless devices are sorted by the received transmitter power from at least one of the one or more wireless devices.

4. The method for connecting with a wireless device of claim 1, further comprising:

determining the signal strength of the one or more wireless devices.

5. The method for connecting with a wireless device of claim 4, further comprising:

receiving a transmitter power from at least one of the one or more wireless devices; and

determining a distance of the one or more wireless devices from the host computing device using the signal strength and the transmitter power of the one or more wireless devices.

6. The method for connecting with a wireless device of claim 5, wherein the one or more wireless devices are sorted using the distance from each wireless device to the host computing device.

7. The method for connecting with a wireless device of claim 1, further comprising:

pre-pairing the one or more wireless devices with the host computing device.

8. The method for connecting with a wireless device of claim 7, further comprising:

setting a user-friendly alias that corresponds to the media access control (MAC) address of the one or more wireless devices;

wherein the names displayed correspond to the user friendly alias of the one or more wireless devices; and

wherein the name comprises up to 28 bytes.

9. The method for connecting with a wireless device of claim 1, wherein the one or more wireless devices are sorted by the order in which the wireless devices were last connected to the host computing device;

and further comprising

pre-selecting one of the one or more wireless devices based on the wireless device most recently connected to the host computing device.

10. A method for connecting to a host computing device, comprising:

activating a Bluetooth®

low-energy radio of a wireless device;

broadcasting a user-friendly name in one or more non-connectable undirected advertising events via the Bluetooth®

low-energy radio; and

forming a Bluetooth®

Classic connection with the host computing device.

11. The method for connecting to a host computing device of claim 10, further comprising:

broadcasting a transmitter power of the wireless device.

12. The method for connecting to a host computing device of claim 11, wherein the user-friendly name comprises up to 28 bytes.

13. The method for connecting to a host computing device of claim 12, further comprising:

pre-pairing the wireless device with the host computing device.

14. The method for connecting to a host computing device of claim 10, further comprising:

deactivating the Bluetooth®

low-energy radio.

15. The method for connecting to a host computing device of claim 10, wherein the user-friendly name comprises up to 31 bytes.

16. A system for communicating vital signs data wirelessly, comprising:

a host computing device including non-transient storage media containing instructions stored thereon, where the instructions, when executed by one or more processors, cause the host computing device to;

receive a Bluetooth®

low-energy broadcast from one or more electronic medical records portal computing devices;

identify one or more electronic medical records portal computing devices that are in a range of the host computing device;

sort the one or more electronic medical records portal computing devices;

display a name for each of the one or more electronic medical records portal computing devices; and

connect to one of the one or more electronic medical records portal computing devices;

wherein the electronic medical records portal computing device includes non-transient storage media containing instructions stored thereon, where the instructions, when executed by one or more processors, cause the host computing device to;

activate a Bluetooth®

low-energy radio;

broadcast a user-friendly name via the Bluetooth®

low-energy radio;

form a Bluetooth®

Classic connection with the host computing device; and

deactivate the Bluetooth®

low-energy radio.

17. The system for communicating vital signs data wirelessly of claim 16, wherein the host computing device is further configured to receive one or more vital sign measurements of a patient;

and

send the one or more vital sign measurements to the electronic medical records portal computing device,

wherein the electronic medical records portal computing device is further configured to receive the one or more vital sign measurements from the host computing device.

18. The system for communicating vital signs data wirelessly of claim 17, wherein the electronic medical records portal computing device is further configured to send one or more of the one or more vital sign measurements to an electronic medical record corresponding to the patient.

19. The system for communicating vital signs data wirelessly of claim 18, wherein the host computing device disconnects from the electronic medical records portal computing device after sending the one or more vital sign measurements.

20. The system for communicating vital signs data wirelessly of claim 16, wherein the host computing device is further configured to:

determine the signal strength of the one or more electronic medical records portal computing devices;

receive a transmitter power from the electronic medical records portal computing device; and

determine a distance of the electronic medical records portal computing device from the host computing device using the signal strength and the transmitter power of the one or more electronic medical records portal computing devices.
