Abstract
An in-vivo observation system provided with a capsule endoscope including an in-vivo observation section, a battery, a magnetic field detection section, a power supply switch that controls a power supply and a power supply control section that causes the power supply switch to operate according to an internal signal from the magnetic field detection section, and a magnetic field generating apparatus including a magnetic field generating section, an operation section that outputs an operation signal according to an operation by a user and a masking section that masks an operation signal inputted to the magnetic field generating section for a predetermined period.
Claims8
An in-vivo information acquiring system comprising:
- an in-vivo information acquiring apparatus introduced into an object to be examined, comprising:
- an in-vivo information acquiring section that acquires information inside the object to be examined;
- a power supply source that supplies power to be used to drive the in-vivo information acquiring section;
- an external signal detection section that detects an external signal and outputs an internal signal according to the detected external signal;
- a power switch that controls a power supply from the power supply source to the in-vivo information acquiring section;
- and
- a power supply control section that causes the power switch to operate according to the internal signal inputted from the external signal detection section, and
- an external signal generating apparatus disposed outside the in-vivo information acquiring apparatus, comprising:
- an external signal generating section that generates the external signal;
- an operation section that outputs an operation signal instructing the external signal generating section to generate the external signal according to an operation;
- and
- a masking section that masks the operation signal from the operation section to the external signal generating section for a predetermined period.
A capsule endoscope system comprising:
- a capsule endoscope to be introduced into an object to be examined, comprising:
- an in-vivo observation section that acquires an image inside the object to be examined;
- a battery that supplies power used to drive the in-vivo observation section;
- a magnetic field detection section that detects a magnetic field signal and outputs an internal signal according to the detected magnetic field signal;
- a power supply switch that controls a power supply from the battery to the in-vivo observation section;
- and
- a power supply control section that causes the power supply switch to perform a toggle operation according to the internal signal inputted from the magnetic field detection section, and
- a magnetic field generating apparatus disposed outside the capsule endoscope, comprising:
- a magnetic field generating section that generates the magnetic field signal;
- an operation switch that outputs an operation signal instructing the magnetic field generating section to generate the magnetic field signal according to an operation by a user;
- and
- a timer that extends a pulse width of the operation signal to the magnetic field generating section from the operation switch for a predetermined period.
