YY 0677-2008 Translated English of Chinese Standard. YY0677-2008: Liquid Nitrogen Cryosurgical Equipmenthttps://www.chinesestandard.net, 12 ก.ย. 2020 - 14 หน้า This Standard specifies the scope, terms and definitions, requirements, test methods, inspection rules, marking, labelling and packaging of liquid nitrogen cryosurgical equipment. This Standard is applicable to cryosurgical treatment equipment which uses liquid nitrogen as the refrigerant and utilizes the latent heat of vaporization phase change for refrigeration, and with the capacity of liquid nitrogen storage greater than 1 L. The cryosurgical equipment mainly generates low temperature to the target tissue, which is used for cryo-necrosis, cryoblock, inflammatory reaction and cryo-adhesion. |
