  • Patent number: 10842928
    Abstract: A medicine-holding body is disposed in a flow path of a nozzle portion of an adapter for blood dispensing. The medicine-holding body is formed of a plurality of fibers which is made of polyester and is bundled by aligning a longitudinal direction thereof in a flowing direction which is a direction in which blood flows. The medicine-holding body holds an anticoagulant for suppressing coagulation of blood, as a medicine to be mixed into blood. The surface area of the medicine-holding body is greater than or equal to 10 mm2 and less than 600 mm2. In a case where the surface area of the medicine-holding body is greater than or equal to 10 mm2, the concentration of the anticoagulant becomes greater than or equal to a lower limit value of 10 U/mL even under most severe conditions such as a dispensing speed of 500 ?L/second. In a case where the surface area of the medicine-holding body is less than 600 mm2, it is possible to maintain the occurrence rate of hemolysis to be less than or equal to 10%.

  • Publication number: 20130076834
    Abstract: A flexible wiring circuit board has a second terminal section bonded and electrically connected to a first terminal section of a wiring circuit board of a discharge die. A drive signal is inputted to the first terminal section through the second terminal section, and then sent to a driver IC. The driver IC drives a piezoelectric element in accordance with the drive signal through a printed wiring pattern. Thereby, ink is discharged from an ink discharge opening. A copper ion diffusion inhibiting film is formed on a surface of a copper wiring member of the second terminal section on contact with a process liquid containing at least one of 1, 2, 3 triazole and 1, 2, 4 triazole. This inhibits diffusion of copper ions and copper ion migration resulting therefrom. Thus, malfunction due to the copper ion migration is inhibited.

  • Publication number: 20090126568
    Abstract: A method for removing intra-microchannel bubbles, which removes bubbles occurring in a microchannel, is provided; the method including: allowing a liquid that contains bubbles and is introduced into a microchannel to flow in a first direction at a first flow speed at which the bubbles float upward and can remain adhered on an inner wall of the microchannel or less; and then allowing the liquid to flow in a second direction that is opposite to the first direction to move a gas-liquid interface of the liquid, which is a rear end of the liquid in the second direction, in the second direction at a second flow speed at which the bubbles adhered on the inner wall of the microchannel can maintain an adhesion position so as to collect the bubbles on the gas-liquid interface and make the bubbles disappear by exposing the bubbles to a gas.
