Abstract

The invention provides a biotelemetry system for disposition on the wrist. The device of the invention may be portable, untethered and in some instances, disposable. The features of the wrist biotelemetry system make it effective in stable, chronic or emergency medical settings.

Claims

1. A device comprising;

(a) two or more sensors, each comprising;

(i) a light emitting source;

(ii) a photodetector spaced apart from said light emitting source and capable of receiving reflected light from said light emitting source;

(c) a substrate adapted to receive and/or support said two or more sensors;

(d) a banding mechanism capable of circumscribing the wrist while remaining in contact with at least 50% of the wrist skin surface; and

(e) a signal processing unit.

2. The device of claim 1 further comprising a means of signal compensation of nitrous oxide (N₂O).

3. The device of claim 1 wherein the banding mechanism comprises a material selected from the group consisting of paper, plastic, metal, metal coated plastic, fabric, pocketed strut and combinations thereof.

4. The device of claim 3 wherein the banding mechanism material is a flexible material.

5. The device of claim 3 wherein the material of the banding mechanism is a pocketed strut and comprises a lengthwise strut enveloped in a plastic pocket whereby providing a bending pressure to the banding mechanism results in the coiling of the strut and ligature of the sensor around the wrist.

6. The device of claim 1 wherein placement of the two or more sensors along the banding mechanism is selected from the group consisting of radial positioning, even distribution, in-line positioning, side-by-side positioning, staggered positioning, zigzag positioning, serpentine positioning and random positioning.

7. The device of claim 1 wherein the two or more sensors are modular and are placed at locations that optimize the signal output.

8. The device of claim 1 wherein signals from the two or more sensors are amplified, filtered and averaged to give an equivalent output signal as a single sensor.

9. The device of claim 1 wherein the substrate comprise a molded plastic template for receiving the two or more sensors, said substrate being affixed to the banding mechanism.

10. The device of claim 9 wherein the substrate is permanently affixed to the banding mechanism.

11. The device of claim 1 further comprising an oximeter monitor connected directly to the signal processing units, wherein said monitor contains at least one display window.

12. The device of claim 11 wherein the monitor contains two or more display windows.

13. The device of claim 11 wherein the at least one display window has a shape selected from the group consisting of circular, square, rectangular, triangular, polygonal, concave polygon, constructible polygon, convex polygon, cyclic polygon, equiangular polygon, equilateral polygon, regular polygon, henagon, digon, quadrilateral, cyclic quadrilateral, kite, parallelogram, equilateral parallelogram, rhomboid, tangential quadrilateral, trapezoid or trapezium, isosceles trapezoid, pentagon, regular pentagon, hexagon, heptagon, octagon, regular octagon, nonagon, decagon, regular decagon, hendecagon, dodecagon, hexadecagon, icosagon, star without crossing lines, star polygon, hexagram, heptagram, octagram, decagram, pentagram, annulus, arbelos, disc, crescent, elliptical, oval, and semicirclular.

14. The device of claim 13 wherein the window shape is circular.

15. The device of claim 1 wherein the signal processing unit comprises a signaling feature which allows remote monitoring of oximetry measurements.

16. The device of claim 1 wherein the dimensions of said sensors are between about 1 mm to about 10 cm in length, between about 1 mm to about 10 cm in width and thickness between about ½

mm to about 3 cm including said substrate.

17. The device of claim 16 wherein the dimensions of said sensors are between about 1 mm to about 5 cm in length, between about 3 mm to about 5 cm in width and thickness between about ½

mm to about 3 cm including said substrate.

18. The device of claim 16 wherein said sensors are of a length selected from the group consisting of from about 5 mm to about 1 cm, from about 0.5 cm to about 5 cm, and from about 3 cm to about 10 cm.

19. The device of claim 16 wherein said sensors are of a width selected from the group consisting of from about 5 mm to about 1 cm, from about 0.5 cm to about 5 cm, and from about 3 cm to about 10 cm.

20. The device of claim 16 wherein said sensors are of a thickness selected from the group consisting of from about 0.5 mm to about 20 mm, from about 5 mm to about 1 cm and from about 0.5 cm to about 3 cm.
