Abstract: In a method of photometric in vitro determination of the content of oxygen in a blood sample, a blood sample is transferred directly from an in vivo locality to an at least partially transparent sample container of a sampling device. The sample container has a measuring chamber containing a luminophor, the luminescence of which is quenched in the presence of oxygen. The luminophor is excited by irradiation with radiation from a radiation source. The luminescence emitted by the excited luminophor is detected by a radiation detector and the oxygen content determined on the basis of the radiation detected by the radiation detector. A sampling device and a system for photometric in vitro determination of oxygen in a blood sample are also described.

Abstract: A method of photometric in vitro determination of at least one blood gas parameter in a sample of whole blood. The whole blood sample is obtained by connecting an at least partially transparent sample container to an in vivo locality and transferring whole blood into the sample container, then breaking the connection. The sample container is arranged in an optical system which has a radiation source and a means for detecting radiation to locate the sample container between the radiation source and the radiation detection means. Radiation is transmitted to the sample from the radiation source and radiation emitted from the sample is transmitted to the radiation detection means. The detected radiation is used to determine the blood gas parameter of the sample. A system for use in this method has a radiation source, a radiation detection means, an at least partially transparent sample container, and a sample container station.

Abstract: A sampling device for photometric determination of the content of an analyte in a sample of whole blood has at least one measuring chamber having two wall parts, at least one wall part being locally transparent, at least one wall part being sufficiently deformable to facilitate displacement of the whole blood sample from the measuring chamber. The measuring chamber also contains a transparent body having a radiation transmission characteristic dependent upon the concentration of a predetermined analyte in the whole blood sample. The sample device is employed in an analyzer for photometric determination of the content of an analyte in a sample of whole blood and in a method of photometric in vitro determination of the content of an analyte in a sample of whole blood.

Abstract: An apparatus for analyzing biological liquids comprises a measuring block including measuring means for measuring characteristics of said liquids. The measuring block is mounted within a thermal shield or housing by means of a base member interconnecting a minor part of the inner wall of the housing and the measuring block so as to define a space between the inner walls of the housing and the measuring block, said space being filled with air or another medium having a poor thermal conductivity.The thermal shield or housing and the base member are made of a material with good thermal conductivity, and heating and/or cooling means are arranged in heat conductive contact with the said shield. The function of the heating and/or cooling means is controlled by a temperature sensor arranged in heat conductive contact with the measuring block, so as to maintain the temperature of said block at a substantially constant predetermined value.
