Abstract
The present invention relates to the field of medical monitoring, and in particular non-contact monitoring and communication with other medical monitoring devices. Systems and methods are described for receiving a video signal of a medical monitoring device that is outputting a light signal, identifying the light signal emitted by the medical monitoring device from the video signal, decoding information from the light signal, and determining a communication from the decoded information related to a patient being monitored or the medical monitoring device itself.
Claims (34)
1. A patient monitoring device, comprising:
a wearable sensor comprising at least one light; and
a processor communicatively coupled with the wearable sensor, the processor configured to:
encode information according to a transmission scheme; and
instruct the at least one light of the wearable sensor to emit a light signal with the encoded information according to the transmission scheme, wherein the light signal is emitted in a field of view captured by a video camera,
wherein the at least one light includes a first light that is configured for use in obtaining information regarding a patient and for emitting the light signal with the encoded information according to the transmission scheme.
2. The patient monitoring device of claim 1 , wherein the wearable sensor includes an opening through which light emitted by the first light can be seen by a video camera.
3. The patient monitoring device of claim 1 , wherein the encoded information relates to at least one of the patient monitoring device and the patient associated with the patient monitoring device.
4. The patient monitoring device of claim 1 , wherein the encoded information relates to one or more patient vital signs.
5. The patient monitoring device of claim 1 , wherein the encoded information relates to patient monitoring device identifying information.
6. The patient monitoring device of claim 1 , wherein the information obtained is patient fingerprint information.
7. The patient monitoring device of claim 1 , wherein the light signal is visible light or infrared light.
8. The patient monitoring device of claim 1 , wherein the patient monitoring device is a pulse oximeter.
9. The patient monitoring device of claim 1 , wherein the encoded information is encoded using frequency modulation.
10. The patient monitoring device of claim 1 , wherein the encoded information is encoded using pulse width modulation.
11. The patient monitoring device of claim 1 , wherein the encoded information is encoded using amplitude modulation.
12. A patient monitoring device, comprising:
a wearable sensor comprising at least one light; and
a processor communicatively coupled with the wearable sensor, the processor configured to:
encode information according to a transmission scheme; and
instruct the at least one light of the wearable sensor to emit a light signal with the encoded information according to the transmission scheme, wherein the light signal is emitted in a field of view captured by a video camera,
wherein the wearable sensor further comprises an optical sensor configured for receiving external signals, and
wherein the processor is further configured to process external signals and instruct the patient monitoring device based on the processed external signals.
13. The patient monitoring device of claim 12 , wherein the external signal is a request for a specific type of information, and the instruction from the processor to the patient monitoring device is to encode the requested information and emit a light signal with the encoded information according to the transmission scheme.
14. A patient monitoring device, comprising:
a wearable pulse oximetry sensor comprising a light emitter and a photodetector for obtaining vital sign information about a patient; and
a processor communicatively coupled with the wearable pulse oximetry sensor, the processor configured to:
encode the vital sign information according to a transmission scheme; and
instruct the light emitter to emit an encoded light signal with the encoded information according to the transmission scheme, wherein the encoded light signal is emitted in a field of view captured by a video camera.
15. The device of claim 14 , wherein the vital sign information comprises respiration rate.
16. The device of claim 14 , wherein the vital sign information comprises oxygen saturation.
17. The device of claim 14 , wherein the vital sign information comprises pulse rate.
18. The device of claim 14 , wherein the encoded information further includes an alarm condition.
19. The device of claim 14 , wherein the wearable pulse oximetry sensor is a wireless contact sensor.
