RADIO-TYPE IN-SUBJECT INFORMATION ACQUISITION SYSTEM, DEVICEFOR INTRODUCTION INTO SUBJECT, AND OUTSIDE-SUBJECT DEVICE

摘要

A pill 1 inserted into a body BDY of a patient acquires in-vivo information on the body of the patient. A receiver 2 disposed on the outside of the body receives the in-vivo information on the body of the patient from the pill 1 through an antenna. When a power supply signal is transmitted from the receiver 2 to the pill 1 through the antenna, a drive control signal for causing the pill 1 to execute a predetermined function is superposed on the power supply signal, which makes it possible to control various functions performed by the pill 1 from the outside of the pill 1.
