【摘要】：针对低温等离子体处理人体皮肤和组织等生物医学应用中开发人体可接触低温等离子体源的需求,本文设计了一种灵活的悬浮电极结构的介质阻挡放电低温等离子体发生装置,来在空气中产生人体可接触的低温等离子体。通过合理的选择绝缘外套来实现手持灵活移动电极,通过合理选择阻挡介质来限制放电电流,实现人体安全接触。本文通过电气和光学特性诊断研究了所设计装置的放电特性,在进行人体接触试验基础上,建立了装置的等效电路模型,来对人体接触的安全性进行论证。结果表明,所设计的电极结构灵活安全,人体可以安全接触,当外加电压在低于5 kV且气隙间距为0.5 mm时,消耗的放电功率小于0.5W,传输电荷小于50nC,放电电流幅值小于10 mA。等效电路模型分析结果表明,当外加电压4 kV至6 kV,且气隙间距小于1 mm时,流过人体的工作电流不超过3.82 mA。
[Abstract]:In order to meet the need of developing human contact low temperature plasma source in biomedical applications such as low temperature plasma treatment for human skin and tissue, a flexible dielectric barrier discharge low temperature plasma generator with suspended electrode structure is designed in this paper. To produce low-temperature plasma in the air that is accessible to the human body. The flexible mobile electrode is realized by selecting the insulating jacket reasonably, and the discharge current is limited by the reasonable selection of the barrier medium, and the human body is in safe contact with each other. In this paper, the electrical and optical characteristics of the designed device are studied. On the basis of human contact test, the equivalent circuit model of the device is established to demonstrate the safety of human contact. The results show that the electrode structure is flexible and safe, and the human body can contact safely. When the applied voltage is less than 5 kV and the gap spacing is 0.5 mm, the discharge power is less than 0.5 W, the transfer charge is less than 50nC, and the discharge current amplitude is less than 10 mA.. The results of equivalent circuit model analysis show that when the applied voltage is 4 kV to 6 kV, and the gap spacing is less than 1 mm, the working current flowing through the human body does not exceed 3.82 mA..
