Biological and Physical Principles and Applications of Electromagnetic Medical Devices
摘要
Abstract
Electromagnetic medical devices refer to a category of equipment used for medical diagnosis and treatment by utilizing electric field, magnetic field, or electromagnetic field. Electromagnetic biological effects including the thermal effects and non-thermal effectsare the main principle and the bases of assessment for innovative electromagnetic medical devices. Physical factors influencing the biological effects include electromagnetic energy as well as permittivity and permeability of organisms. Thermal effects are evidenced by temperature rise. The cells do not suffer from obvious injury, such as the reversible and/or irreversible damage injury caused by the process of coagulation, drying, carbonization or vaporization, which make it able to be applied in high-frequency therapy, microwave tumor therapy, radiofrequency ablation, electric surgery,etc. Non-thermal effects is evidenced bybiochemical and physiological response in the molecules, cells, tissues, organs and body with no temperature rise in the organism when exposed to the electromagnetic field, which can be applied to pacemakers, heart defibrillation, extracorporeal shock wave lithotripsy, and so on. In recent years, research has carried out in both the basic principles and equipment of electromagnetic medical devices. Some electromagnetic medical devices were developed, such as electromagnetic-phoresis apparatuses, transdermal drug delivery, and irreversible electroporation tumor therapy. Effective means of safety control of electromagnetic medical device is to establish the electromagnetic limit standard and to implement according to the standard based on human physiological integrity.关键词
