    Abstract: A medical device that can confirm a predetermined portion in a medical instrument implanted for use in a body. A medical instrument includes a main body part, and a medicinal solution container installed in the main body part. A notification part includes a plurality of light emitting portions that emit light by use of power received by a power receiving part to notify that a predetermined state is reached, when a relative positional relation between a power transmission part and the power receiving part reaches the predetermined state by moving the power transmission part, and a soft part into which an injection needle is inserted, the plurality of light emitting portions are arranged along an outer edge of the soft part. A first coil is a coreless coil disposed to have an inner diameter larger than an outer diameter of the medicinal solution container.

    Abstract: A power transmission unit includes a second coil which contactlessly transmits power, a power reception unit includes a first coil that receives the power transmitted from the power transmission unit, and a medical instrument includes the power reception unit and is embedded in a body. The medical instrument includes a notification unit that is composed of a plurality of light emitting units that provides notification that a relative positional relationship between the power transmission unit and the power reception unit has reached a predetermined state by emitting light using the power received at the power reception unit when the predetermined state is reached by the movement of the power transmission unit. A soft unit into which an injection needle is inserted, the plurality of light emitting units being arranged so as to extend along an outer edge of the soft unit.
