In-vivo information acquisition apparatus and in-vivo information acquisition apparatus system
First Claim
1. An in-vivo information acquisition apparatus system comprising:
- an in-vivo information acquisition apparatus for acquiring in-vivo information at an examination site in a body cavity;
a capsule medical apparatus having a storage section for storing the in-vivo information acquisition apparatus, a release unit for releasing the in-vivo information acquisition apparatus at the examination site, and a casing formed in a capsule shape;
an external antenna arranged outside a body to transmit and receive a signal to and from the in-vivo information acquisition apparatus;
an external apparatus that acquires a signal transmitted by the in-vivo information acquisition apparatus from the external antenna and has an identifying section for identifying the identification information possessed by a labeling section arranged inside the in-vivo information acquisition apparatus;
a position-detecting section provided in at least one of the capsule medical apparatus and the external apparatus to detect a location of the in-vivo information acquisition apparatus in a body, the capsule medical apparatus releases the in-vivo information acquisition apparatus based on the location information of the capsule medical apparatus acquired by the position-detecting section, the position-detecting section includes;
a magnetic-field generating section provided in the capsule medical apparatus;
an external magnetic sensor arranged outside a subject; and
a third determining section provided in the external apparatus to determine the location of the capsule medical apparatus based on a vector of a magnetic field generated by the magnetic-field generating section; and
an external control section provided in the external apparatus to transmit a common control signal to a plurality of the in-vivo information acquisition apparatuses,wherein the capsule medical apparatus further includes a timer and a control section for controlling the release unit; and
wherein the control section controls the release unit in a manner such that a desired number of the in-vivo information acquisition apparatuses are released from the release unit to the outside at a desired time based on time information of the timer.

Abstract
There is provided an in-vivo information acquisition apparatus capable of detecting high-accuracy in-vivo information substantially at the same time in a plurality of different examination sites in a body cavity and an in-vivo information acquisition apparatus system capable of introducing a plurality of in-vivo information acquisition apparatuses into a patient at the same time. The in-vivo information acquisition apparatus includes a specimen-collecting section for collecting a specimen at an examination site in a body cavity, a specimen-evaluating section for evaluating the specimen collected by the specimen-collecting section and outputting an evaluation result, a labeling section having identification information unique to the in-vivo information acquisition apparatus, a communication section for receiving a signal transmitted from the outside and for transmitting to the outside the evaluation result output by the specimen-evaluating section, and a power supply section for supplying electrical power.
