▎ 摘　　要

NOVELTY - The pump has a control circuit board (1) placed in a shell. A touch screen (2) is fixed on the shell. A infusion bottle is mounted on a transfusion bottle supporting seat. A sealing joint (8) is connected with the infusion bottle. A flow control mechanism (9) is clamped on a liquid infusion tube (24) of a infusion observing bottle (22) to control infusion flow. An end of a heating metal pipe (21) is detachably connected to a liquid inlet of the infusion observing bottle through an infusion cannula. A graphene heating film (70) is covered on an outer tube wall of the heating metal pipe. The graphite heating film is connected with the control circuit board. USE - Constant temperature pump. ADVANTAGE - The pump has stable heat source by providing constant temperature, and quickly heats liquid, and avoids potential safety hazard. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a constant temperature pump.
