COMBINED APPARATUS FOR MEASURING THE BLOOD GLUCOSE LEVEL FROM AN OCULAR FLUID

摘要

A combined apparatus for measuring the blood glucose level from an ocular fluid comprises a hand-held fluorescence photometer (D1) for determining the glucose level of the ocular fluid and a device (D2) for the amperometric or photometric determination of the blood glucose level. The fluorescence photometer (D1) comprises: first irradiating means (7,8,10) for providing a pilot beam (1) for irradiation of the eye (3) in order to excite a first fluorescence comprising a first wavelength band; first detecting means (8,9,12,13) for measuring the intensity of the of the pupil fluorescence within the first wavelength band; second irradiating means (17,18,21) for providing a measurement beam (5) for irradiation of the eye in order to excite an ocular sensor (4) to emit a second fluorescence comprising a second wavelength band; second detecting means (18,19,20,22,23,24,25) for measuring the intensity of the second fluorescence within the second wavelength band. The first and second irradiating means are arranged such that the measurement beam irradiates the eye under a predetermined angle (a) between 0<0> and 90° and at a predetermined distance from the pilot beam.
