Document Type and Number:

WIPO Patent Application WO/2014/178512

Kind Code:

A1

Abstract:

Provided is a heating device for blocking the flow of air if the inside of a cartridge enters a negative-pressure state upon discontinuing or completing the supply of a transfusion liquid or blood being infused into a human body, the device comprising: a cartridge upper plate which is formed so as to have an inflow port and is formed so as 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 and is formed 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 lower plate and heats the fluid being guided by means of the fluid-guide members; air filters which are positioned outside the fluid-guide members and are adapted to discharge, into the atmosphere, air bubbles that are generated in the heated fluid; and a means which is provided on the cartridge upper and lower plate fluid flow pathways, keeps the flow of fluid normal in the positive-pressure state and blocks the fluid movement pathway if a negative pressure occurs inside the cartridge.
