Abstract:
A probe suitable for use in the non-invasive sensing of glucose concentrations in the body of a patient, said probe comprising: at least three radiation receiving fibers extending between a probe body and a spectrograph, and spaced apart from each other in a substantially uniform manner and aligned in a predetermined fixed pattern at said probe body, a radiation transmitting means for conducting radiation from a radiation source and extending from the radiation source to the probe body, with said radiation transmitting means formed in said probe into ring means for conducting radiation in a ring-shaped area immediately surrounding each of said receiving fibers, with said radiation transmitting means and said receiving fibers terminating at said probe body in a unitary structure having an outer surface configured for contacting the skin of a patient, wherein the ring means passes radiation from said radiation source and into the patient in the areas immediately surrounding each receiving fiber and the receiving fibers detect said radiation passing back out of the patient and pass said detected radiation to the spectrograph.
