Abstract
An induction device for photodynamic therapy and diagnosis is used in a living body, and for activating a photochemical reaction of a photosensitive agent in the living body. The induction device comprises a transmitter, and a light irradiator implanted in the living body. The transmitter is used for emitting a radio signal to penetrate a superficial layer of the living body. When the light irradiator receives the radio signal, the light irradiator emits light by the driving signal, such that the photosensitive agent undergoes a photochemical reaction.
Claims21
An induction device for photodynamic therapy and diagnosis, used in a living body, for activating a photochemical reaction of a photosensitive agent in the living body, the induction device comprising:
- a transmitter, for emitting a radio signal to penetrate a superficial layer of the living body;
- and
- a light irradiator, implanted in the living body, and comprising:
- a first induction coil, for receiving the radio signal;
- a control circuit, electrically connected to the first induction coil, for converting the radio signal into a driving signal;
- and
- a light emitting element, electrically connected to the control circuit, wherein the light emitting element is driven by the driving signal to emit light, such that the photosensitive agent undergoes a photochemical reaction.
A light irradiator for photodynamic therapy and diagnosis, implanted in a living body, wherein the light irradiator emits light through a radio signal penetrating a superficial layer of the living body, so as to activate a photochemical reaction of a photosensitive agent in the living body, the light irradiator comprising:
- a first induction coil, for receiving the radio signal;
- a control circuit, electrically connected to the first induction coil, for converting the radio signal into a driving signal;
- and
- a light emitting element, electrically connected to the control circuit, wherein the light emitting element is driven by the driving signal to emit light, such that the photosensitive agent undergoes a photochemical reaction.
