MAGNET BODY AND DRUG DELIVERY CONTROL DEVICE USING MAGNET BODY

摘要

A magnetic body that may be suitably applied to a drug delivery system using magnetism, may be provided. Furthermore, a drug delivery control device that allows the magnetic body to be suitably applied to drug delivery, is provided. The magnetic body includes a magnet; and a cover part attached to an edge of the magnet. The cover part is composed of a material with high magnetic permeability, and a ratio of a length to a radius of the cover part is 10:1 to 7: 3. The drug delivery control device includes the magnetic body including the magnet; and the cover part attached to the edge of the magnet, a head for supporting the magnetic body; and a drive mechanism of the head that causes the head to operate along a projected region formed by the affected area with respect to a surface of a tissue. A magnetic field is applied from the magnetic body to the affected area where a magnetic drug is administered.
