Implantable sensor and system for in vivo measurement and control of fluid constituent levels |
| abstract |
An in vivo implantable sensor (10) obtains spectra of body fluid constituents, and processes the spectra to determine the concentration of a constituent of the body fluid. The sensor includes an optical source (12), and detector (16). The source emits light at a plurality of different, discrete wavelengths, including at least one wavelength in the infrared region. The light interacts with the body fluid and is received at the detector. The light at the plurality of different wavelengths has a substantially collinear optical path through the fluid with respect to each other. When measuring fluid constituents in a blood vessel (14), such as blood glucose, the light at the plurality of different wavelengths is emitted in a substantially single period of time. The spectra are corrected for artefacts introduced from extraneous tissue in the optical path between the source (12) and the detector (16). |
