  • Patent number: 5217875
    Abstract: A method for detecting biological activities in a specimen, for instance a blood sample, employing a sealable container with a culture medium, into which the sample is introduced, wherein metabolic processes are enhanced in the presence of microorganisms in the sample, thereby causing changes to take place in the concentrations of the substances subject to such processes. The concentration changes are measured by optodes that are in direct contact with the sample, and by an excitation and detection assembly assigned to these optodes, to which is connected an evaluation unit for determining concentration changes of the substances over time.

  • Patent number: 5114676
    Abstract: In order to improve the response behavior of an optical sensor for determining at least one parameter in a liquid or gaseous sample, the sensor including a substrate which is provided with carrier particles and a fluorescent indicator immobilized thereon, the substrate is configured as a polymer film transparent to both excitation and emission radiation, and the individual carrier particles carrying the fluorescent indicator in immobilized form are bonded with only part of their surface to a thin layer of a thermoplastic material adhering to the polymer film and assume thermosetting properties after the carrier particles have been pressed in, whereas the other part of the surface of the carrier particles extend into an optically transparent hydrogel layer which covers the thermoplastic layer and in which the carrier particles are anchored mechanically. Such sensors may easily be attached to the end of an optical waveguide and may be made in any size by a simple punching operation.

  • Patent number: 5108932
    Abstract: For the simultaneous measurement of two parameters of a liquid or gaseous sample, in a fluorescence measuring device in which the influence of the aging processes of the indicator substance and the fluctuations in the light intensity of the excitation light source are to be avoided, it is proposed that the change in the first parameter to be measured is obtained from the change in the ratio of two intensity values, determined for different wavelengths of the excitation and emission spectrum of the indicator substance, and the change of a second parameter is obtained from the change in the decay time t of the fluorescence radiation of the same indicator substance from the group of aromatic hydrocarbons, the aromatic heterocycles and the metal organic complexes.

  • Patent number: 5097834
    Abstract: In order to determine at least one parameter of interest in a living organism, a perfusion fluid is directly introduced in the tissues. After its partial balancing by the tissue parameter of interest, the perfusion fluid is collected and analyzed for the parameter of interest, as well as for endogenous or exogenous marker properties indicative of the degree of interaction between the perfusion fluid and the tissue, in such a way that the parameter of interest can be determined with the help of such characteristic properties. Contrary to usual processes, used exclusively inside blood vessels or other body cavities filled with liquid, this process creates in the tissues, i.e. in the closed cellular structure, a previously inexistent cavity, in which the perfusion fluid introduced in the tissue interacts directly with the organic tissue, with no intervening membranes.

  • Patent number: 5080865
    Abstract: In order to improve a one-way measuring element, which may be inserted into an analyzer for analyzing gaseous or liquid samples and which comprises a measuring channel with a measuring zone and one or more sensors located therein, the proposal is put forward that the one-way measuring element be provided with a sensor part whose measuring channel has seals on both ends, and with a sample-taking part, and that a coupling element be placed at the inlet end of the measuring channel for direct coupling of the sample-taking part containing the gaseous or liquid sample, and that the measuring channel be filled with a calibrating and storage medium prior to the measuring process, and that the calibrating and storage medium contained in the measuring channel be displaced by the sample flowing in after the sample-taking part has been coupled to the sensor part. The one-way measuring elements obtained in this way are characterized by great simplicity of design and ease of handling.

  • Patent number: 5039490
    Abstract: Due to the size of the devices used for the excitation and measuring of light, conventional sensor elements for optically determining the concentrations of substances contained in gaseous and liquid samples, featuring an indicator layer with one or more indicator substances, are not well suited for use with microanalysis equipment, nor are they easy to mass-produce. These disadvantages are eliminated by using a unitary sensor element having a carrier layer, at least one photosensitive element with electric contact leads in contact with the carrier layer, and an indicator layer containing an indicator substance.

  • Patent number: 5017339
    Abstract: An apparatus for measuring the properties of a sample includes a sensor block with at least one sensor module whose housing contains a measuring chamber in contact with a sensor, the housing of the sensor module M including a mixing chamber for indirect measurement of a sample property, which chamber is placed upstream of the measuring chamber, and is connected with a sample channel and a reagent channel. Due to the modular design of the sensor block, the sample and reagent paths in the sensor block or sensor module may be kept short; along with the compact arrangement of mixing chamber and measuring chamber this permits the required sample and reagent volumes to be kept to a minimum.

  • Patent number: 4917864
    Abstract: In conventional devices for feeding an analyzing apparatus with different media, comprising a feeder unit with fittings for the media to be introduced, the individual media travel different paths between the input opening and the measuring chambers, which will result in different conditions of measurement for calibrating media and sample media. The invention eliminates this drawback by providing the feeder unit 1 with input elements 6, by placing the sample input opening 4 on a supporting piece 3 which may be moved by a control unit 17, and by providing that each input element 6 may be brought into sealing contact with the sample input opening 4 subsequent to a rotatory motion of the supporting piece 3.
