A light emitting type capsule treatment tool for irradiating light with a specific wavelength required for photoimmunotherapy, includes a power receiving coil, a magnetic member, a light emitting member and a capsule. The power receiving coil is formed by winding a conductive wire and configured to receive electric power supplied from an external transmission antenna via a magnetic flux. The magnetic member is placed on an inner circumference of the power receiving coil. The light emitting member is configured to be supplied with electric power from the power receiving coil and to emit the light with the specific wavelength. The capsule houses the power receiving coil, the magnetic member and the light emitting member.

Light-emitting capsule treatment tool

One embodiment provides a power supply device for supplying power to a medical device main body implanted in a human body. The power supply device includes a power supply coil configured to supply power wirelessly to a power reception coil provided in the medical device main body from outside the human body through electromagnetic induction. And, the power supply coil includes: a cylindrical coil formed by winding a lead wire helically; and a ring-shaped member made of a magnetic material and is disposed so as to surround an outer circumference of the cylindrical coil.
