Is the Shanghai Guanrui high potential therapy machine approved by the state?

It is class 3, but the state of class 3 medical devices is so that, is used to support life, life-sustaining, potentially dangerous, the need for strict control of its safety and effectiveness of medical equipment. It is approved, but already in 2005, it should be expired, and then people themselves have electricity, if you use the external electricity, I personally feel is not good.
