  • Patent number: 11543420
    Abstract: A blood clotting time measurement cartridge includes: an inlet on one end of a measurement flow channel and through which blood is introduced; a communication opening on the other end of the measurement flow channel and through which air suction or air pressure application or the blood introduced from the inlet is performed; a moving body arranged in the measurement flow channel moves; a clotting accelerator applied on at least one of a flow channel wall surface, which defines the measurement flow channel, and the moving body; and a detection area through which light is transmitted to a predetermined part in the measurement flow channel, and where it is possible to detect with light whether there is the moving body or the blood making a reciprocating motion in the measurement flow channel in association with air suction or air pressure application or the blood from the communication opening.

  • Publication number: 20220011295
    Abstract: A blood clotting time measurement cartridge that can keep an amount of blood constant while simplifying a configuration and easing a blood injection operation, and a blood clotting time measuring device using the cartridge. The cartridge includes a measurement flow channel wherein blood is housed and transmission of light detects whether there is blood in a predetermined position, an introduction opening on one end side of the channel from which blood is introduced, a communication opening on the other end through which it is possible to cause, by suction or pressurization of air or blood introduced from the introduction opening, the blood in the channel to make a reciprocating motion so as to pass through the predetermined position, a partition wall that partitions a blood injection space connected to the introduction opening, and an absorption member on an outer side of the partition wall that absorbs blood beyond the wall.
