1 122, 124, and 126 is approximately 2mm. (Specification
2 19).
3 4. Steuer is directed to non-invasive monitoring of hematocrit
4 and other blood parameters of a patient (col. 1, ll. 14-17).
5 5. The sensor-emitter separation distances of Steuer are
6 important to provide a detection region in the subdermis 12.
7 The determination of optimum sensor 3 separation and
8 aperture 8 sizes is done empirically. Minimum sensor
9 separation and aperture diameters can be established. (col.
10 12, ll. 17-30).
11 6. Fig. 1B of Steuer illustrates a reflective mode system where
12 emitters 1 and photodiodes 3 are on the same side of the
13 patient's finger.
14 7. Soller is directed to a non-invasive optical and mathematical
15 method of measuring hematocrit. (col. 1, ll. 44-46).
16 8. Figs. 13 A and B of Soller describe a hematocrit measuring
17 device having a separation distance between the LEDs 804
18 and the detector 805 of 2-4mm. (col. 18, l. 66 to col. 19,
19 l. 3).
20 9. In addition, Soller describes that a separation of 1-5mm
21 between the illuminating fibers and receiving fibers
22 facilitates adequate depth penetration into the tissue. (col.
23 21, ll. 19-24).
24 10. Arakaki is directed to an optical method for non-invasive
25 measurement of muscle tissue oxygen saturation to calculate
