Abstract：Skin anesthesia is widely used in medical cosmetology or acupuncture, for the drug anesthesia is limited and inefficient
semiconductor refrigeration is difficult to meet requirements of low temperature. In the present study, a medium cycling skin
cooling machine based on compression refrigeration was developed, which could lower the cooling head temperature to -10℃. The
performance was tested separately when the cooling temperature was 2℃, 0℃, -2℃, -4℃ and -6℃. It showed that when the cooling
head temperature was -4℃ to -6℃, the skin could get anesthesia state within 10-15 s. The machine has advantages of security, energy
conservation and convenience, and is expected to be valuable for the further development and application.
