  • Patent number: 11559636
    Abstract: Provided is a warming device which can efficiently warm a blood product and inhibit a liquid in a warming flow path from exceeding an upper limit temperature thereof when liquid delivery of the blood product is stopped. The warming device includes the warming flow path in which the blood product flows and a heat plate which is in contact with the warming flow path to supply heat to the warming flow path. On the heat plate, a heater in a predetermined pattern corresponding to the warming flow path is disposed. The heater is disposed such that an amount of heat generation toward the warming flow path decreases in stages from an upstream side toward a downstream side in the warming flow path and that a decrease rate of the amount of heat generation at each of the stages decreases from the upstream side toward the downstream side.

  • Patent number: 11413403
    Abstract: Provided is an infusion system including: a liquid container that accommodates a blood derivative; a heating device that heats the blood derivative; an air bubble removal chamber that removes air bubbles in the blood derivative; a first flow path that connects the liquid container and the heating device to each other; a second flow path that connects the heating device and the air bubble removal chamber to each other; a third flow path that connects the air bubble removal chamber and an infusion unit to each other; a fourth flow path that connects the air bubble removal chamber and the liquid container to each other; a first pump provided in the first flow path; and a second pump provided in the third flow path. The heating device has a heating flow path where the blood derivative flows and a heat supply body that contacts the heating flow path.
