Study Of Targeting Magnetic Field Generator For The Treatment Of Cerebral Thrombosis

In the field of treatment of cerebral thrombosis and other diseases targeting the treatment system are gradually emerging and coming into the field of view.The magnetic targeting drug delivery system as a targeted drug delivery system is an important one.In recent years nature has become a hot research.The so-called magnetic targeted drug delivery system, by means of the carrier means is guided by magnetic fields which ligand or antibody drug through the gastrointestinal tract for topical administration.Systemic circulation positioned selectively concentrated in the target tissue.target organ,the target cell or cells within the structure of the delivery system. For the current market most of the guidance magnetic field strength and the magnetic field gradient is inappropriate and can not be evenly distributed in space. In this paper we propose a magnetic field and the steepness of the good.The space can be uniformly distributed in the magnetic field generator targeted programs.This paper further studies the electric wrench diver and goes in for the following jobs:(1)We compare several different targeting magnetic field generation and ultimately determine the use of the electromagnetic coil is suitable for generating a magnetic field targeted.(2)Magnetic targeting drug delivery system of particles in motion the process is relatively complex.In the process of physical movement field analysis, we would like to provide a theoretical basis for later.(3)This paper presents a new geometric model using ansoft finite element simulation software to simulate and optimize the final establishment of the targeted magnetic field coils produce a model.In the simulation environment the size of each sub-coil radius were analyzed and compared in order to determine the specific parameters.(4)In the field of the size of each sub-coil current, magnetic field focusing on the use of genetic algorithms to optimize the performance resulting in a combination regimen current best sub-coils in the model case. After optimization of the magnetic field and before optimization comparing, you can see that optimize the performance of the optimized magnetic field has greatly improved.(5) In the field of the charging circuit hardware design, in order to get better wavy effect, we decided to use IGBT parallel manner, and to use EXB841 driven manner and simulation.(6) Finally we summary the main work.Through this work we verify the feasibility of targeting electromagnetic coil generates a magnetic field.We would like to provide a reference for future research work in this area.
