摘要:
This invention is generally related to a biocompatible sensor for detecting/measuring sugar, especially glucose, in an ocular fluid in a non-invasive or minimally invasive manner and a method for using the biocompatible sensor. A biocompatible sensor of the invention comprises, consists essentially, or consists of an ophthalmic device comprising a molecular sensing moiety which interacts or, reacts with sugar to provide an optical signal which is indicative of sugar level in an ocular fluid.

Disclosed is an ocular sensor (110) for detecting at least one analyte in eye water. Said ocular sensor (110) comprises at least one sensor material that is designed to change at least one optical property in the presence of the at least one analyte. The ocular sensor (110) further comprises at least one sensor chip which is fitted with at least one integrated optical detector (122) for detecting the optical property. Also disclosed is a measuring system (166) for detecting at least one analyte in eye water. Said measuring system (166) encompasses an ocular sensor (110) according to the invention as well as an evaluation unit (168) which is designed to exchange data with the sensor chip (118).
摘要:
The present invention relates to a hand-held fluorescence photometer and method for measuring an analyte level, preferably a blood glucose level, from an ocular fluid. The photometer is based on a dual beams measuring system and it is capable of defining the correct positioning for the measurement. Only when the apparatus is correctly positioned the actual analyte measurement automatically takes place.

摘要:
The invention relates to a sensor element (110) for detecting at least one analyte in a body or a body tissue (130), in particular for determining at least one metabolite concentration in a body fluid. Said sensor element (110) comprises an implantable, single-piece moulded body (112) which comprises a sensor end (114) and a coupling end (116). Said moulded body (112) comprises, in the region of the sensor end (114), at least one sensor area (118) which comprises at least one sensor material (122). Said sensor material (122) modifies, in the presence of the analytes, at least one optically measurable property. Said moulded body (112) also comprises at least one optically transparent coupling part (120) which is adapted to transmit electromagnetic radiation to at least one spectral range between the sensor area (118) and the coupling end (116). The moulded body (112) comprises, in the sensor area (118), at least one optically transparent matrix material (124). The analyte can at least partially diffuse through the matrix material (124) to the sensor material (122). The sensor material (122) is embedded in the matrix material (124). The coupling part (120) is at least partially formed by the matrix material (124).
