Abstract

A medical device system includes one or more anti-loss/anti-theft mechanisms. The medical device system comprises a wireless medical device and a docking station. An alarm is activated on one or more of the wireless medical device or the docking station when an alarm threshold is detected by one of the anti-loss/anti-theft mechanisms.

Claims

1. A medical device system that includes one or more anti-loss/anti-theft mechanisms, the medical device system comprising:

a wireless medical device that includes a wireless medical sensor; and

a docking station,

wherein an alarm is activated on one or more of the wireless medical device or the docking station when an alarm threshold is detected by one of the anti-loss/anti-theft mechanisms.

2. The medical device system of claim 1, wherein the alarm is activated when the wireless medical device is removed from the docking station and not returned to the docking station for a time period that exceeds a predetermined threshold.

3. The medical device system of claim 1, wherein the alarm is activated when a temperature measurement is taken using the wireless medical device and the wireless medical device is not returned to the docking station after the temperature measurement is taken for a time period that exceeds a predetermined threshold.

4. The medical device system of claim 1, wherein the docking station further includes a state machine that keeps track of a plurality of stages in a temperature measurement process using the wireless medical device, and wherein the alarm is activated when the state machine indicates that an alarm condition has occurred.

5. The medical device system of claim 1, wherein the alarm is activated when a distance between the wireless medical device and the docking station exceeds a predetermined threshold.

6. The medical device system of claim 1, wherein the wireless medical device is electronically associated with the docking station.

7. The medical device system of claim 1, wherein the wireless medical device includes a connector that permits the wireless medical device to connect to an electronic computing device.

8. The medical device system of claim 7, wherein an identity of the docking station is displayed on the electronic computing device when the wireless medical device is connected to the electronic computing device.

9. The medical device system of claim 1, wherein the alarm is activated when a distance between the wireless medical device and a pairing device exceeds a predetermined threshold.

10. The medical device system of claim 9, wherein the pairing device is a clinician'"'"'s badge or the docking station.

11. The medical device system of claim 1, wherein the alarm is activated when a pager button is pressed on the docking station.

12. The medical device system of claim 1, wherein a clinician authentication is required before the wireless medical device is removed from the docking station.

13. The medical device system of claim 1, wherein a temperature reading obtained using a wireless thermometer probe is only displayed on the docking station.

14. The medical device system of claim 1, wherein the alarm may be an audible alarm or a visual alarm.

15. A method for preventing loss or theft of a wireless medical device, the method comprising:

removing the wireless medical device from a docking station;

when the wireless medical device is removed from the docking station, monitoring a parameter associated with the wireless medical device and the docking station;

determining whether the parameter exceeds a first threshold; and

when the parameter exceeds the first threshold, activating an alarm.

16. The method of claim 15, wherein the parameter is a time that the wireless medical device has been removed from the docking station.

17. The method of claim 15, wherein the parameter is a distance of the wireless medical device from the docking station.

18. The method of claim 15, wherein a mating association is established between the wireless medical device and the docking station.

19. The method of claim 15, further comprising activating the alarm when a distance between a clinician badge and the docking station is greater than a second threshold.

20. The method of claim 15, further comprising activating the alarm on the wireless medical device when a pager button is pressed on the docking station.

21. The method of claim 15, further comprising:

taking a temperature measurement using a wireless thermometer probe; and

displaying a temperature reading on the docking station when the wireless thermometer probe is returned to the docking station.

22. The method of claim 21, further comprising preventing the temperature reading from being displayed on any other electronic computing device except the docking station.

23. An electronic computing device comprising:

a processing unit; and

system memory, the system memory including instructions that when executed by the processing unit cause the electronic computing device to;

process a clinician authentication;

store clinician authentication information, the clinician authentication information including a time stamp;

access the clinician authorization information;

when a determination is made that the clinician is authorized, release a wireless thermometer probe from the electronic computing device;

display identification information for the clinician on the electronic computing device;

start a timer when the wireless thermometer probe is released from the electronic computing device;

determine whether the wireless thermometer probe has been returned to the electronic computing device within a predetermined time interval; and

when a determination is made that the wireless thermometer probe has not been returned to the electronic computing device within the predetermined time interval, activate an alarm on the wireless thermometer probe.

24. The electronic computing device of claim 23, wherein the identification information includes a photograph of the clinician.
