DEVICE FOR MEASURING THE BLOOD-SUGAR LEVEL IN HUMANS

摘要

The invention relates to a device for measuring the blood-sugar level in humans. Said device comprises the following: a catheter the free end of which is inserted in a blood vessel, said catheter comprising at least one optical fiber; a light source for feeding light to the at least one optical fiber; a measuring site at the free end of the catheter where the light emerges from the at least one optical fiber, the light being scattered by the blood and/or being guided through the blood and the scattered and/or guided light being fed to at least one return optical fiber; a detector for receiving the returned light; an arithmetic unit for evaluating the light received by the detector. The aim of the invention is to improve this device in such a manner that measuring values of the blood-sugar content can be obtained that are as exact as possible and continuous over time and that can be used for data processing. To this end, a purification device is provided at the measuring site that removes tissue debris deposited from the blood.
