Methods, analytical devices and analytical systems are provided for determining at least one analyte concentration in a body fluid sample. The methods, which may be incorporated into the devices and systems, can include the following steps: applying a body fluid to a test carrier; illuminating the test carrier by at least one light source, where the at least one light source is modulated by using at least two modulation frequencies; receiving light remitted by the test carrier by using at least one detector; determining an analyte concentration by evaluating at least one detector signal generated by the detector, where the detector signal is demodulated with the at least two modulation frequencies to generate at least two demodulated detector signals, each demodulated signal corresponding to one of the modulation frequencies; and detecting a fault by comparing the at least two demodulated detector signals.

Methods of determining an analyte concentration in a body fluid sample, as well as analytical devices and systems for use therein

A measuring module for remission photometric analysis of one or a plurality of specimens is provided with the following features: a transmitter with a transmission channel for transmitting a measuring radiation to location of the specimen; a first focusing device for focusing the measuring radiation on the specimen; a receiver with a receiving channel to receive the radiation reflected by the specimen; a second focusing device made of plastic for focusing the measuring radiation reflected by the specimen onto the receiver, whereby the second focusing device further comprises a filter which is designed to filter a fluorescence radiation from the specimen excited by the measuring radiation.

Measuring module for remission photometric analysis and method for the production thereof

A coding for a medical disposable item is proposed comprising at least one information component in encoded form. Associated encoding methods and devices, and associated decoding methods and devices, are also proposed. The coding generally comprises an optical information component comprising one or more fields filled with a gray-scale value up to a certain degree of filling. Each gray-scale value and degree of filling are associated as a value pair determined as part of a code generated to correlate to an information component desired to be applied to and conveyed from a medical disposable item to an associated device that utilizes such items.

Encoding method for encoding medical items

A portable medical system is provided for the purposes of analysis and/or medication, the system having at least one of a medical monitoring device, an analysis device and a medication device. The portable medical system comprises at least one display element comprising at least one organic light-emitting diode display. An optimization device can be provided that comprises a brightness sensor and is configured to optimize the brightness, contrast and/or power consumption of the at least one display element. Furthermore, a monitoring device can be provided which monitors the functionality of the display element. Faults in the display element can be detected in this way, and a corresponding warning can be output to a person using the portable medical system.

Analysis system with user-friendly display element

An analysis system for detecting at least one analyte in a sample is proposed, in particular for detecting glucose in a bodily fluid. The analysis system is designed to detect the analyte using at least one test element. The test element has at least one analysis zone for detecting the analyte. The test element includes at least one coding with at least one test element specific item of information and/or at least one position specific item of information. The analysis system includes a detector and furthermore at least one transfer device which is designed to afford the detector the possibility of acquiring the analysis zone in at least a first position and to afford the detector the possibility of acquiring the coding in at least a second position which differs from the first position.

Analysis system with coding recognition

The invention relates to embodiments of an analysis system and to a method for analyzing a sample on an analytical test element, with the analysis system comprising a test element receptacle for receiving and positioning a test element in an analysis position. In an exemplary embodiment, the test element receptacle contains a guide part and a lock part, the guide part having means for guiding a test element into and out of the analysis position, the lock part comprising a frame and a bolt element, which frame and bolt element are connected to one another by a hinge. The bolt element can be pivoted about the hinge between a first position and a second position with respect to the frame. The bolt element comprises a latching lug for engaging in a recess in test element when the bolt element is in the first position and when the test element is positioned in the analysis position.

Analysis system and method for analyzing a sample on an analytical test element

A system and method for measuring and evaluating optical signals for detecting an analyte in an analysis liquid.

System and method for acquiring and evaluating optical signals

The invention relates to embodiments of a method and a system for monitoring the correct positioning of a test element in a test element receptacle of an analysis unit, the test element carrying a sample to be analyzed by the analysis unit. Using a delimiting element, responsive signals resulting from irradiating an analysis region on the test element are effectively prevented from impinging upon a signal detector when the analysis region is in an incorrect position relative to the analysis unit. The delimiting element is provided with a light-opaque region and a light-transmissive region, and the light-opaque region is positioned such that responsive signals impinge upon it rather than the light-transmissive region when the analysis region is in an incorrect position. The embodiments of the invention further relate to methods and systems configured to further analyze the sample, to determine whether the sample has been underdosed, and additional position monitoring steps comprising irradiating different partial regions of the analysis region and comparing the detection signals responsive to each to a predetermined limit value.
