Provided is a heating device for blocking flow of air if the inside of a cartridge enters a negative-pressure state upon discontinuing or completing supply of a transfusion infusion solution or blood being infused into a human body, the device including: a cartridge upper plate which is formed so as to have an inflow port and to have a fluid-guide member for guiding the flow of a fluid; a cartridge lower plate which is formed so as to have an outflow port so as to have another fluid-guide member positioned spaced apart from said fluid-guide member; a heater which is disposed between the cartridge upper plate and the lower plate and that heats the fluid being guided by means of the fluid-guide members; air filters which are positioned outside the fluid-guide members and that are adapted to discharge air bubbles that are generated in the heated fluid into the atmosphere; and means which are provided on the cartridge upper and lower plate fluid flow pathways, that keep the flow of fluid normal in the positive-pressure state and block the fluid movement pathway if a negative pressure occurs inside the cartridge. |
