摘要

考虑了磁性技术在医学实践中用于靶向药物递送到致病区域的特点以及用于此目的的磁性装置设计的特殊性。注意到在这些装置的开放磁性系统中使用永磁体的特殊性。结果表明，在一定条件下，使用高矫顽力的钕磁体是可取的。建立了数学模型，并得到了计算钕磁体产生的磁场的解析公式，以保证磁性纳米颗粒沿血管的运动。

The Features of Force Field Mathematical Model of Neodim Magnet in Drug Delivery Device

The features of magnetic technologies application in medical practice for targeted drug delivery to pathogenic zones and the peculiarities of designs of magnetic devices intended for this purpose are considered. The specificity of using permanent magnets in open magnetic systems of these devices are noted. It is shown that, under certain conditions, the use of highly coercive neodymium magnets is preferable. Mathematical models were compiled and analytical formulas were obtained to calculate force fields created by neodymium magnets, which ensure the movement of magnetic nanoparticles along the body vessels.
