CAPSULE MEDICAL DEVICE AND CAPSULE MEDICAL DEVICE SYSTEM

摘要

A capsule medical device in which a biological information detection device is smoothly guided in a body cavity by a magnetic field applied from the outside to the body. The capsule medical device (1) has the biological information detection device (5) for detecting biological information inside a body cavity, a magnet (12) for receiving a guidance magnetic field applied from the outside of the body and generating drive force, a coil (7) for receiving a magnetic field for position detection applied from the outside of the body and generating a position detection signal, a filter device (8) connected to the coil (7) and attenuating a guidance signal component of the guidance magnetic field made to enter the coil (7), and a wireless transmission device (10) for outwardly transmitting both a position detection signal having passed the filter device (8) and the biological information detected by the biological information detection device (5).
