3d Rotating Magnetic Field Locator Magnetic Field Spatial Distribution

Tumor target oriented therapy is medicinal research hotspot and difficulty at present. Target oriented carrier at present primary contains antibody carrier, conjugant and active amylase carrier. Oriented principle is based on biology specialty. Every carrier is selective for drug orientation. It is effective for specifically tumor therapy. This paper puts forward nanometer-iron particles as drug carriers. These carriers can orientate to tumor focus by effect of the 3D rotated magnetic field. This paper is absorbed in studying of the distributing of the rotated 3D magnetic field.In order to orientate the drug carrier to tumor focus, it need form insensitive magnetic field, satisfies the condition of the nanometer-iron particles influx. In order to solve the problem this paper sets forth following study:(1) This paper depicts the study of tumor target orientated therapy at domestic and overseas at present, and then brings forward nanometer-iron particles as drug carrier.(2) This paper introduces the principle of the electromagnetic field, then designs out the model of the 3D rotated magnetic field and explains the orientated theory of the 3D rotated magnetic field.(3) This paper achieves the magnetic field intensity and the variety law at various conditions by the MathCAD soft, builds the model of finite element and simulates magnetic field, educes the appropriate technique parameter.(4) This paper manufactures the tiny model apparatus of the 3D rotated magnetic field in order to prove the simulated result.The simulated result and tiny model apparatus result are all perfect. These results provide the theory for the therapy apparatus manufacture.
