Method and device for determining oxygen saturation of hemoglobin, for determining hematocrit of blood, and/or for detecting macular degeneration |
摘要 |
A method and device for accurately determining oxygen saturation of hemoglobin by the measurement of the optical density of a sample, such as a blood vessel, in response to illumination by light having at least three wavelengths (λ1,λ2,λ3, . . . ) within a range of about 460 nm to about 523 nm. The hematocrit of a sample may be determined from optical density measurements at the three or more wavelengths in conjunction with a known path length. The device may be an intravenous or intra-arterial fiber optic catheter used to deliver the interrogating light signal to the blood and to detect the reflected signal. A method and device of determining the thickness of the retinal well using spectroscopic information are also disclosed. |
