[0038] Among them, the maximum heating temperature of the tungsten wire 7 is forty degrees Celsius, and the heating area of ​​the tungsten wire 7 is about ten square centimeters. By limiting the heating temperature and heating area of ​​the tungsten wire 7, it is beneficial to control the conversion of liquid nitrogen into gas while reducing the impact of heating on the temperature of liquid nitrogen, thereby ensuring the cooling effect of the device.

[0039] Working principle: first, align the block 29 with the rotating pile 32 and slowly place it on the top of the rotating pile 32. Through the action of the spring, the block 29 is clamped on the outer edge of the rotating pile 32, so that the head cooling device is connected to the rotating pile 32. The head cooling device is rotated to a suitable angle through the roller 33. At this time, the tungsten wire 7 is powered on for heating, and then the valve 18 is opened to release the liquid nitrogen in the liquid nitrogen tank 4. The liquid nitrogen is converted from liquid to gas through the heating of the tungsten wire 7, and then the fan 12 is started. Then, according to the size of the patient's head, the control block 41 is rotated to adjust the headrest 39 to a size suitable for the patient. Finally, the support rod 44 is assembled through the slide groove 42 to support the head cooling device.
