METHOD AND DEVICE FOR PHYSICALLY TARGETING LOCATION OF MAGNETIC DRUG USING PERMANENT MAGNETS

摘要

Disclosed are a device for physically targeting location of magnetic drug and method for physically targeting location of magnetic drug using the device. Said device comprises three permanent magnets I, II and III with a regular shape, and the three permanent magnets tightly arrange in turn in the same direction, wherein shape and size of two permanent magnets I and III at two sides are the same and two permanent magnets I and III are symmetrical from left to right with central line of middle permanent magnet II as a symmetry axis; along the arrangement direction, the magnetization directions of three permanent magnets arrange according to Halbach array; and the surface for targeting location, i.e. work surface, is continuous. The device can provide higher magnetic field intensity and magnetic field gradient, and can induce magnetic drug particles to locate at deeper part in human body.
