NOVELTY - The application claims a perfusate heating device, comprising: a clamping-type graphene temperature heater E1 for heating; a temperature sensor B1 for detecting the temperature; a main control chip U1, for driving the clamping type graphene the constant temperature heater E1, according to the temperature feedback temperature sensor B1, driving the power-off protection circuit for power-off protection. The application model adopts the clamping type graphene the constant temperature heater E1, using the way of clamping not directly contact the liquid in the perfusion tube 1, avoids the liquid in the perfusion tube 1 caused by pollution, at the same time, the heating sheet can improve the heat conduction efficiency by using the graphene, better heating the perfusion tube 1, reducing the area needed to be heated, and matched with the constant temperature heater, the temperature sensor B1 and the main control chip U1 can realize the precise control of the heating temperature and further ensure the heating and safety by the power-off protection circuit, better suitable for the ophthalmic operation requirement, it can safely and controllably heat the existing ophthalmic perfusion tube 1.
