Digestive tract medication administration system and medication administration capsule

Abstract

A digestive tract medication administration system and a medication administration capsule are provided. In an assembled state, with the constraint of a limit structure formed by a rotation limit pin on an inner shell of the capsule and a rotation limit slot in an outer shell of the capsule, and an angle exists between the N-S directions of the first magnetic column and the second magnetic column, a torque is present between the two magnetic columns, which makes parts inside the capsule tightly coupled. When an external magnetic field is applied, at least one or both of the two magnetic columns rotate under the action of the external magnetic field. When the external magnetic field is applied, the administration ports are in opened state, and when the external magnetic field is removed, the administration ports are in closed state.
