Abstract:
1. A temperature control device for liquid medicines, comprising: a flow path block made of a chemical resistant resin, including groove-shaped flow paths through which liquid medicines flow, at both of front and back surfaces thereof; heat-transmitting plates respectively disposed at both of the front and back surfaces of the flow path block so as to face the groove-shaped flow paths; and thermo-modules respectively disposed at outer surfaces of the heat-transmitting plates, and performing a cooling operation or a heating operation on the liquid medicines flowing through the groove-shaped flow paths via the heat-transmitting plates, wherein at least one ridge of a sealing projection portion surrounding a periphery of each of the groove-shaped flow paths is integrally formed with the flow path block by a part of the flow path block at sealing surfaces respectively formed at both of the front and back surfaces of the flow path block, wherein the heat-transmitting plates are fixed to the flow path block in a state of pressure-contacting the sealing projection portions, respectively; and a concave groove having a depth reaching a rear of the sealing projection portion is formed at an outer peripheral surface of the flow path block in a manner so as to surround the flow path block, and a sealing auxiliary member formed of a rubber-elastic material having a heat resistance and a chemical resistance for applying a pressurizing force to the sealing projection portion is fitted into the concave groove; and wherein a normal of the outer peripheral surface is orthogonal to a normal of the front and back surfaces of the flow path block.
