Wireless in-vivo information acquiring apparatus, wireless in-vivo information acquiring system, and communication apparatus

摘要

A communication apparatus (3) arranged outside a subject (1) has an external device (32) which sequentially transmits control signals. A capsule endoscope (2) is introduced inside the subject (1). Thereafter, a system control circuit controls a driving of an intra-capsule function executing circuit so as to start driving at a previously set given time, by supplying driving power to the intra-capsule function executing circuit to control the driving thereof based on a result of detection by a control-signal detecting circuit which is provided in the capsule endoscope (2) and which detects a discontinuous state of input of the control signals. Thus, a collection and transmission of images inside the subject can be performed accurately. In addition, a transmitting unit generates and transmits a communication confirmation signal to the communication apparatus. In response, a receiving unit receives a communication permission signal from the communication apparatus. A communication controller determines whether to transmit in-vivo information or not based on the state of reception of the communication permission signal.
