  • Patent number: 10859590
    Abstract: According to one embodiment, an automatic analyzing apparatus includes a liquid tank, a first pump, a dispensing probe, and a thermal exchanger. The liquid tank stores a first liquid. The first pump pressurizes and sends the first liquid supplied from the liquid tank. The dispensing probe uses the first liquid that is sent out from the first pump as a pressure transmitting medium. The thermal exchanger exchanges heat between an atmosphere in the automatic analyzing apparatus and the first liquid in at least a part of a first flow path connecting the first pump to the liquid tank.
    Type: Grant
    Filed: March 12, 2018
    Date of Patent: December 8, 2020
    Assignee: Canon Medical Systems Corporation

  • Patent number: 8912008
    Abstract: An automatic analyzer analyzes a measurement item by making a sample and reagent react with each other and measuring the reaction result. This apparatus allows parameters associated with reagent dispensing executed by a reagent dispensing mechanism to be set as a dispensing condition for each measurement item or each type of reagent, and controls the reagent dispensing mechanism on the basis of the dispensing condition.

  • Patent number: 8778153
    Abstract: An ion sensor includes a sensor main body having a channel for a sample and an opening connected to the channel, a responsive portion which is filled in the opening and selectively responds to a specific ion, an electrode which has a ring shape, is set such that a central axis of the ring is substantially perpendicular to a central axis of the channel, and senses the response, and an output terminal which is formed out of one metal plate out of which the electrode is formed, has a pin shape, and is held by the sensor main body such that an axis extends along a direction substantially perpendicular to the central axis of the channel and the central axis of the ring.

  • Patent number: 4549809
    Abstract: A photometric measurement method for producing readout signals indicative of light absorption of samples contained in a series of cylindrical cuvettes arranged in a movable cuvette carrier for successively conveying said cuvettes into the path of a measuring light beam directed onto a radiation detector, wherein readings are taken at precisely measured intervals as a function of the width of the cuvette, the rate of movement of the cuvette and the required number of measurements, and a selected reading is taken at the same distance from the leading wall of each cuvette.
