Plasma medicine is an emerging field where plasma physics is used for therapeutical applications. Temperature is an important factor to take into account with respect to the applications of plasma to biological systems. During the treatment, the tissue temperature could increase to critical values. In this work, a model is presented, which is capable of predicting the skin temperature during a treatment with a radio frequency driven plasma needle. The main gas was helium. To achieve this, a discharge model was coupled to a heat transfer and fluid flow model. The results provide maximum application times for different power depositions in order to avoid reaching critical skin temperatures.
等离子体医学是一个新兴领域，其中等离子体物理学被用于治疗应用。就等离子体在生物系统中的应用而言，温度是一个需要考虑的重要因素。在治疗过程中，组织温度可能会升高到临界值。在这项工作中，提出了一个模型，该模型能够预测使用射频驱动等离子体针治疗期间的皮肤温度。主要气体是氦气。为了实现这一点，将放电模型与传热和流体流动模型耦合。结果提供了不同功率沉积下的最大应用时间，以避免达到临界皮肤温度。
