  • Patent number: 8916113
    Abstract: An automatic chemical analyzer in which a reaction solution is stirred by air ejected from an air ejection hole placed above a reaction container. The reaction region can be washed and cleaned sufficiently without causing damage, such as exfoliation of a coating reagent. A reaction container disk 161 is provided with a pore 240 and a pressure detector 241 connected with the pore. Before and after the stirring operation, the ejection hole (nozzle) 170 ejecting air is moved and the output value of the pressure detector is compared with a previously measured normal value. With a discharge pipe 1101 and a suction pipe 1102 inserted to the opening of the reaction container 1140 to be close to both ends of the opening and the side wall of the container, the reaction region 1150 at the bottom of the container is washed by continuous discharge and suction of cleaning fluid.

  • Patent number: 8906326
    Abstract: A biochemical reaction cassette having a structure for uniformizing a liquid flow in a reaction chamber with a simple additional arrangement is provided. A fluid resistive section is arranged in a channel that is constructed to include an injection port, a reaction chamber, and a discharge port. The fluid resistive section decreases the cross-sectional area of the channel to decrease the fluid resistance at ends in the width direction of the fluid resistive section and at positions remote from the injection port and the discharge port, where the flow rate is decreased.

  • Publication number: 20140356234
    Abstract: Improvements in and relating to devices for receiving liquid samples A device for receiving a liquid sample may form part of a micro sampling head for an instrument such as a spectrophotometer. The device receives a liquid sample to be analysed by a process involving the passing of electromagnetic radiation through the sample, and comprises a light inlet guide (20) for directing electromagnetic radiation into the sample, a light receiving element (23) situated in an opposed relationship to the guide and spaced from the guide by a fixed distance to define a fixed path length gap (21), which is, in use, filled with the sample. In use, radiation is passed from the light inlet guide to the light receiving element (23), and the path length of radiation through the sample is defined by the gap (23). The device is open or openable to allow a droplet of sample to be deposited directly in the gap.

  • Patent number: 8900514
    Abstract: The invention discloses a blood analyzing device (100) comprising a holder (110) arranged for carrying a container (10) having a cuvette (20) containing a blood sample (30). The container (10) is positioned in the holder (110) so that a longitudinal axis (60) of the cuvette (20) is angled relative a horizontal axis (70). A light source (120) provides light (40) into the sample (30) and a detector (130) detects the output light (50) from a sub-portion of the blood sample (30). Kinetic information indicative of the change in hemoglobin concentration in a measuring volume (32, 34) is determined by a Hb processor (145) from the detected output light (50). An ESR processor (140) determines the erythrocyte sedimentation rate of the sample (30) based on the kinetic information.

  • Patent number: 8895152
    Abstract: The invention relates to a method for generating at least one electrically contactable area on a polymer which is doped with a conductive substance, wherein a contact material is applied onto the polymer, which has a lower specific resistance at 23° C. than the polymer. According to the invention the contact material is applied onto the polymer so tightly that close contact between the contact material and the conductive substance is achieved. Due to the tight application of the contact material, which has a lower specific resistance than the polymer, the input resistance of the doped polymer is effectively reduced. The invention further concerns a formed body made of a polymer which is doped with a conductive substance, which has at least one contactable area, within which a contact material is applied onto the polymer, which has a lower specific resistance at 23° C. than the polymer.
