Non-invasive glucose sensor system
First Claim
1. A non-invasive glucose sensor system for determining the sugar content in a user'"'"'s blood,said system comprising radiation emitting means for emitting radiation of certain wavelengths,radiation detecting means for detecting the emitted radiation,said radiation detecting means spaced apart from but in line with said radiation emitting means,means for mounting said radiation emitting means and radiation detecting means so that said radiation is capable of being transmitted through the cornea of the user'"'"'s eye, andenabling means for enabling said detecting means to determine the optical rotation of the radiation occurring in the cornea.

Abstract
A unique glucose sensor to determine the glucose level in patients, for example, for use in treating or diagnosing diabetes. The patient'"'"'s eye is automatically scanned using a dual source of polarized radiation, each transmitting at a different wavelength at one side of the cornea of the patient. A sensor located at the other side of the cornea detects the optical rotation of the radiation that passed through the cornea. The level of glucose in the bloodstream of the patient is a function of the amount of the optical rotation of the radiation detected at the other side of the cornea of the patient. The result is transmitted to a remote receiver that is coupled to a readout device to thereby provide non-invasive glucose determinations of high specificity and reliability.

9. A method of obtaining the sugar content of a person non-invasively, said method comprising the steps of:
-
generating a pair of radiation rays and polarizing said pair of radiation rays; transmitting said polarized radiation rays through the cornea of a patient'"'"'s eye; filtering said polarized radiation rays received from said cornea through a polarized filter; and detecting the filtered polarized radiation rays which have been passed through the cornea of the patient'"'"'s eyes; and translating the detected radiation rays to obtain a readout indicative of the sugar content of the patient'"'"'s blood. - View Dependent Claims (10, 11, 12, 13, 14, 15)
