Abstract

A multiple sensor wireless wearable device measuring oxygen saturation and/or heart rate includes a single housing, two or more sensors, each having a pick up beam, an alarm generator, and a timer generator. The two or more sensors, the alarm generator, and the timer generator are all housed inside the single housing, and the two or more sensors are placed in specifically selected placements that avoid their respective pick up beams crossing each other. The housing is a garment specifically designed for containing the device.

Claims

1. A multiple sensor wireless wearable device measuring parameters comprising oxygen saturation and/or heart rate, said device usable on a hand of a user and comprising:

a single housing comprising a hand garment,

two or more pulse oximeter sensors each having a pick up beam,

an alarm generator for delivering an alarm related to the measurement of said parameters, and

a timer generator,

wherein said two or more sensors, said alarm generator and said timer generator are all housed inside said hand garment,

wherein said two or more sensors are placed in specifically selected placements that avoid their respective pick up beams crossing each other, and

wherein said two or more sensors measure the same parameters, and the parameters are used by the device to minimize delivery of false alarms by the alarm generator.

2. The device according to claim 1, wherein the two or more sensors are placed each on a finger.

3. The device according to claim 2, wherein the placement of each of the sensors is on the base portion of each finger.

4. The device according to claim 1, wherein at least one of the two or more sensors is placed each on a zone of the palm of the hand.

5. The device according to claim 1, wherein the placement of each of the sensors is on the inner side of a wrist band or wrist watch.

6. The device according to claim 4, wherein the placement of the at least one sensor placed on a zones of the palm of the hand is at a portion near the base of the hand and distal from the thumb.

7. The device according to claim 1, wherein if none of the sensors is receiving a signal the device does not trigger an alarm.

8. The device according to claim 1, wherein if none of the sensors is receiving a signal a processor triggers a timer with a predetermined time delay.

9. The device according to claim 1, wherein if the sensors are all receiving signals below a certain predetermined alarm triggering threshold value the alarm generator will trigger the alarm output signal with zero delay.

10. The device according to claim 1, wherein if at least one sensor measures a value below a predefined alarm threshold and another sensor receives no signal, the output alarm signal is triggered without delay.

11. The device according to claim 1, wherein if at least one sensor measures a value below a predefined alarm threshold and another sensor receives no signal, the output alarm signal is triggered after a predefined delay.

12. The device according to claim 1, wherein one of the two or more pulse oximeter sensors measures blood oxygen saturation and another one of the two or more pulse oximeter sensors measures heart rate.

13. The device according to claim 1, wherein one of the two or more pulse oximeter sensors measures Heart Rate Variability (HRV).

14. The device according to claim 1, wherein at least two of the pulse oximeter sensors measure identical parameters.

15. The device according to claim 1, wherein each of said parameters has associated an independent timer.

16. The device according to claim 14, wherein as soon as the alarm is triggered by one of said parameters, the timer of another of the parameters is deactivated.

17. The device according to claim 1, wherein triggering of the alarm is blocked if one of the two or more sensors is measuring normal values, and the rest of the two or more sensors are measuring abnormal values.

18. The device according to claim 1, including a GPS function for controlling the user'"'"'s geographical position and measuring the speed at which the user is moving, as soon as the device detects constant vehicle speed greater than a predetermined value during a predetermined period a personalized and autonomous alarm threshold setting program is activated for the user, and wherein the device triggers an alarm if the user'"'"'s heart rate is below a predetermined threshold.

19. The device according to claim 1, wherein said device outputs measurement results and said measurement results are shown on a display mounted on the device, on a Smartphone or on a computer.

20. The device according to claim 1, wherein said device outputs measurement results and said measurement results are transmitted to said smartphone or said computer via a wired USB connection.

21. The device according to claim 1, wherein said device outputs measurement results and said measurement results are transmitted to said smartphone or said computer via a wireless connection.

22. The device according to claim 1, wherein, when the device is carried by the user and in contact with skin of the user, the device generates an alarm signal together with a transcutaneous electrical nervous stimulation on the skin of the user.
