Abstract

An activation device activates a capsule medical device that has a first coil inside and is activated when voltage not less than a first specified value or current not less than a second specified value is generated in the first coil. The activation device includes: a case; a second coil that is provided in the case and is configured to generate a magnetic field when current flows through the second coil; and a guide portion for guiding to a position that is located outside the case and that is a position of the capsule medical device where the capsule medical device can be activated based on the magnetic field generated by the second coil. The capsule medical device is housed at a specified position in a specified posture in a container having a specified shape. The case has a placement surface on which the container is configured to be placed.

Claims

1. An activation device for activating a capsule medical device that has a first coil inside and is activated when voltage greater than or equal to a first specified value or current greater than or equal to a second specified value is generated in the first coil, the activation device comprising:

a case;

a second coil that is provided in the case and is configured to generate a magnetic field when current flows through the second coil; and

a guide portion for guiding to a position that is located outside the case and that is a position of the capsule medical device where the capsule medical device can be activated based on the magnetic field generated by the second coil,

wherein the capsule medical device is housed at a specified position in a specified posture in a container having a specified shape,

the case has a placement surface on which the container is configured to be placed, and

the guide portion includes;

a detection unit configured to detect a position of the capsule medical device placed on the placement surface and to output a signal indicating the position; and

a guidance unit configured to guide the container to a specific position on the placement surface where the capsule medical device can be activated when the container is placed on the placement surface, based on the signal.

2. The activation device according to claim 1, wherein when the second coil generates a magnetic field with a predefined pattern, and voltage or current having a predefined pattern is generated in the first coil, the capsule medical device is activated.

3. The activation device according to claim 1, wherein the guidance unit includes a light-emitting element provided on the placement surface.

4. The activation device according to claim 1, wherein

the container is provided with a portion to be detected that can be detected by the detection unit, and

the detection unit outputs the signal when detecting the portion to be detected.

5. The activation device according to claim 1, further comprising a control unit configured to cause current to be applied to the second coil based on the signal outputted by the detection unit.

6. An activation device for activating a capsule medical device that has a first coil inside and is activated when voltage greater than or equal to a first specified value or current greater than or equal to a second specified value is generated in the first coil, the activation device comprising:

a case;

a second coil that is provided in the case and is configured to generate a magnetic field when current flows through the second coil; and

a guide portion for guiding to a position that is located outside the case and that is a position of the capsule medical device where the capsule medical device can be activated based on the magnetic field generated by the second coil,

wherein the guide portion includes;

a signal generator configured to generate a signal to apply a test current to the second coil;

a magnetic field detection unit configured to detect a change in magnetic field outside the case; and

a control unit configured to cause the current applied to the second coil to increase when the magnetic field detection unit detects the change in magnetic field greater than or equal to a specified value.

7. The activation device according to claim 6, wherein the guide portion further includes an indication display unit configured to perform a specified display according to the change in magnetic field detected by the magnetic field detection unit.

8. The activation device according to claim 7, wherein the indication display unit is at least one of a light-emitting element, an indicator, and a display panel, which are provided on the placement surface.
