Abstract

A monitoring device for measuring one or more physiological parameters of a medical patient can include a finger clip sensor connected to a monitor. An accelerometer in the finger clip sensor detects patient motion or movement that may interfere with monitoring. In response, the monitor displays a message alerting the patient to stop moving or a game in which the objective requires the patient to hold his or her finger still. The device can delay measurement until the patient is still enough and remains still long enough for a clear measurement.

Claims

1. A noninvasive medical monitoring device, the monitoring device comprising:

a sensor having a housing comprising an upper shell and a lower shell pivotally connected together, the upper and lower shells each shaped to accept body tissue of a medical patient;

one or more emitters disposed in the housing, the one or more emitters configured to impinge light on the body tissue of the patient;

one or more detectors disposed in the housing, the one or more detectors configured to receive the light after attenuation by the body tissue of the patient and to output one or more intensity signals responsive to the attenuated light;

a 3D accelerometer disposed in the housing, the 3D accelerometer configured to detect movement of the sensor and to output data related to the detected movement; and

a monitor configured to receive output from said physiological sensor and said 3D accelerometer;

wherein the monitor comprises a display and content displayed on the display is based at least in part on output from said 3D accelerometer.

2. The noninvasive medical monitoring device of claim 1 wherein the sensor is connected to and communicates with the monitor via a cable.

3. The noninvasive medical monitoring device of claim 1 wherein the sensor is connected to and communicates with the monitor via a wireless connection.

4. The noninvasive medical monitoring device of claim 1 wherein content displayed on the display comprises one or more verbal messages.

5. The noninvasive medical monitoring device of claim 1 wherein content displayed on the display comprises a movement or balance game.

6. The noninvasive medical monitoring device of claim 1 wherein the monitor further comprises a data storage device.

7. The noninvasive medical monitoring device of claim 1 wherein the monitor further comprises a network interface.

8. A noninvasive medical monitoring device, the monitoring device comprising:

a physiological sensor;

a 3D accelerometer associated with the physiological sensor, the 3D accelerometer configured to detect movement of the sensor and to output data related to the detected movement; and

a monitor comprising a display and a processor;

wherein the processor is configured to process output data from the 3D accelerometer related to the detected movement and generate content based at least in part on said output from said 3D accelerometer.

9. The noninvasive medical monitoring device of claim 8 wherein the sensor and 3D accelerometer are connected to and communicate with the monitor via a cable.

10. The noninvasive medical monitoring device of claim 8 wherein the sensor and 3D accelerometer are connected to and communicate with the monitor via a wireless connection.

11. The noninvasive medical monitoring device of claim 8 wherein content generated by the processor comprises one or more verbal messages.

12. The noninvasive medical monitoring device of claim 8 wherein content generated by the processor comprises a movement or balance game.

13. The noninvasive medical monitoring device of claim 8 wherein the monitor further comprises a data storage device.

14. The noninvasive medical monitoring device of claim 8 wherein the monitor further comprises a network interface.

15. The noninvasive medical monitoring device of claim 8 wherein the processor is further configured to display a message on the display prompting a user for input regarding a type of content to be generated.

16. A method of measuring one or more physiological parameters of a patient, said method comprising:

detecting movement and position of a measurement site on a patient with a sensor, wherein said sensor is connected to and communicates with a monitor;

displaying content on a display on said monitor based at least in part on the detected movement and position of said measurement site;

emitting optical radiation to said measurement site on said patient;

detecting attenuated optical radiation from said measurement site on said patient; and

determining an output measurement value indicative of a physiological parameter based on the detected attenuated optical radiation.

17. The method of claim 16, further comprising delaying the emitting of said optical radiation to said measurement site on said patient until the detected movement and position of said measurement site are within acceptable limits.

18. The method of claim 16, further comprising prompting a user for input regarding a type of content to be displayed on said monitor.

19. The method of claim 16, further comprising storing data related to the detected movement and position of said measurement site over time.

20. The method of claim 16, further comprising outputting data related to the detected movement and position of said measurement site over time.
