摘要： A test apparatus for measuring blood characteristics comprises a measuring head having a measuring electrode and a reference electrode arranged in spaced relationship and a closure membrane covering a portion of said head, and an attachment connectable to said head having a wall defining a support membrane which is engageable on the closure membrane. The attachment defines a chamber for the blood sample in which the support membrane forms a bottom wall thereof so that the membrane supporting the blood is in contact with the closure member and thus is capable of being heated by a heater contained in the head without coming into contact with or contaminating the blood sample. The attachment while permitting the measurement to be made does not allow the blood being tested to come into contact with the measuring head. The attachment may be either disposed of or cleaned for re-use.

摘要： An electrochemical gas sensor with a stacked arrangement of electrodes and nonwoven layers arranged in parallel, comprising at least one measuring electrode (3) and at least one counterelectrode (5). A porous membrane (8) that is permeable to air is in contact with the stacked arrangement of electrodes and nonwoven layers arranged in parallel at least on one side, at least one layer of a hydrophilic nonwoven (7) is located between the electrodes. The porous membrane (8) that is permeable to air and the hydrophilic nonwoven (7) extend into a separate equalization volume (9), which is filled with electrolyte at least partially and is located at least partially in one plane with the electrodes. The separate equalization volume (9) surrounds the electrode arrangement at least partially in this plane, and the porous membrane (8) that is permeable to air is exposed to ambient pressure at least in partial areas. Such sensors are characterized by a flat shape, high insensitivity to shocks, independence from the position, and high tolerance to variations in environmental humidity.

摘要： An electrochemical gas sensor for detecting gaseous components in the environment has a diffusion membrane, a measuring electrode, a counterelectrode, and, if desired, a reference electrode, pressed together in a disk stack, which are accommodated in a pot-shaped cover, which in turn is beaded around the sealing edge (6) of a housing pot (1). A compression spring (21) in the housing pot (1) presses a wick disk (20) against the measuring electrode (12), so that a constant and pressurized, intimate and sealed positioning of the disk stack is guaranteed. It is achieved as a result that no additional contact leads from the electrodes to the outer space of the sensor to the measuring and evaluating unit are needed, so that leakage-free sealing of the sensor to the outside is possible, and that a constantly stable, reproducible measured signal is obtained because of the defined and narrow electrolyte film on the surface of the measuring electrode.

摘要： A method is disclosed for calibrating transducers for determining gas concentrations, in particular for the transcutaneous measurement of blood gases. In the method, the testing chamber is exposed on its measuring surface, through an overlay, to a known gas concentration. The method provides for a simpler application of the calibration medium to the measuring surface of the transducer, such that an overlay provided with substances required for furnishing the known gas concentration is applied directly onto the measuring surface of the testing chamber, covering it. An overlay is also disclosed and is embodied as a paper strip having two impregnated zones, separated from one another by an intermediate piece provided with a coating.
