摘要:
A power supply apparatus supplies power to a body-insertable apparatus from outside a subject. The body-insertable apparatus is introduced into the subject and obtains intra-subject information. The power supply apparatus includes a first electric cable which is wound around a circumferential surface of a garment and forms a coil, the garment covering the subject, the coil having a non-directionality at a time of power supply; and a power supply unit which supplies power to the body-insertable apparatus in a contactless manner through the coil.

In a capsule endoscope illuminating units are disposed around an image capturing unit in such a manner that an optical axis of the illuminating units do not intersect with an optical axis of the observation unit, and illumination areas of the illuminating units overlap at substantially a central portion of an image capturing area of the image capturing unit.

An in-body information acquiring apparatus includes a function executing unit that realizes a predetermined function inside a body of a patient. A power-supply circuit includes a power unit that includes a cell and that outputs a first current and a first voltage; and a converter that converts the first current to a second current, which is a current required to operate the function executing unit for a predetermined time, and converts the first voltage to a second voltage, which is a voltage required to operate the function executing unit.

A transmitting and receiving apparatus (2) that transmits a radio signal to a capsule endoscope includes: a transmitting level determining unit (25) disposed near a transmitting resonance circuit (22); a frequency controller (26) that controls an oscillation frequency based on a result of determination executed by the transmitting level determining unit (25); and a frequency variable oscillator (16) that changes the oscillation frequency, based on the control of the frequency controller (26). By changing the oscillation frequency so that a transmission level becomes large, the oscillation frequency can be changed so as to decrease a frequency difference between the oscillation frequency and the resonance frequency of the resonance circuit (22) that changes along a variation in a self inductance value of a coil (24).

摘要:
A pill inserted into a body of a patient acquires in-vivo information on the body of the patient. The in-vivo information on the body of the patient is input to a receiver from the pill through a receiving antenna. The pill receives a power-supply signal from the receiver through a power receiving antenna, and a power recovering circuit recovers power from the power-supply signal. A level determining circuit compares the power recovered with a predetermined value to determine the strength of the power-supply signal, and wirelessly transmits the determination result signal to the receiver.

A pill inserted into a body of a patient acquires in-vivo information on the body of the patient. A receiver disposed on the outside of the body receives the in-vivo information on the body of the patient from the pill through an antenna. When a power supply signal is transmitted from the receiver to the pill through the antenna, a drive control signal for making the pill to execute a predetermined function is superposed on the power supply signal, which makes it possible to control various functions performed by the pill from outside.
