Warming apparatus with heater produced by PCB

Abstract

The disclosed invention relates to a heating apparatus having a PCB-type heater capable of allowing the temperature of Ringer's solution or blood which is introduced into a blood vessel, when transfusing a blood thereto, to be equal to that of the human body to thereby provide an accurate resistance value. The present invention comprises 1. A heating apparatus according to an embodiment of the invention comprises a body including a first connecting portion having a tube which is connected to the first connection portion and receives a fluid supplied from an instillation room, a path having the shape of a spiral screw thread to enable the fluid to flow and a second connecting portion for supplying the fluid flowing through the path to an injection syringe; an inner cover inserted into the body and fixedly attached thereto in a prescribed adhesive manner for preventing the fluid from flowing out; a middle cover for closely fixing the body and the inner cover against each other; a PCB-type heater inserted into the inside of the top and bottom surfaces of the middle cover for heating the fluid flowing through the path so that the fluid is maintained at a prescribed temperature; a bottom case having a box portion to receive the body having the heater and the middle cover coupled thereto; and a upper case coupled to the bottom case.
