[0040] Such as Figure 7 andFigure 8 As shown, the flexible electrode 1 employs a three-electrode structure, and the first metal electrode 102 is a high pressure metal electrode, and the second metal electrode 104 and the copper sheet 105 constitute a low pressure metal electrode, connected to the low pressure end of the power source, and high pressure metal. Between the strips 1021 and the low pressure metal strip 1041, each high pressure metal strip 1021 is provided between the two low pressure metal strips 1041, and the high pressure metal strip 1021 and the low pressure metal strip 1041 are always kept parallel to each other. This is a key copper piece 105 that is uniformly discharged from the flexible plasma device to cover the high voltage metal strip 1021 and the low pressure metal strip 1041. The breakdown voltage of the flexible electrode is lowered by the flexible electrode structure of the three-electrode, and therefore discharge can be achieved in a very compact plasma reactor, and the temperature of the reactor can be effectively reduced. Such as Figure 9 As shown, it is a three-electrode structure temperature change.

[0041] Such as figure 2 Design, the two sides of the flexible electrode 1 is provided, respectively, the first female buckle 107, the second female buckle 108, the first female buckle 107, and the second female buckle 108 penetrate the first metal electrode 102, respectively. The second metal electrode 104 is provided with a non-buduated 204 on the metal plate 3, the male buckle 204 and the female buckle 107. By designing the metal buckle 3, the flexible electrode can be easily conveniently fixed in the sealing bag.

The circular protective cover is covered to protect the metal male interface 203. The other end of the metal male member 203 is connected to the metal press buckle 204, and the exposed metal portion passes through the sealed bag 4. The structure of the power interface 2 allows the sterilization process to maintain a sealed environment before and after the sterilization process, and it can be guaranteed that the medical device does not have secondary infection during the transportation process.
