Capsule-type medical apparatus

Abstract

A capsule-type medical apparatus includes a capsule-shape sealed container accommodating an electric component for executing a predetermined function; and a switch unit arranged in a substantially center of the sealed container, and controlling supply of electric power for driving the electric component according to action of a magnetic field from outside of the sealed container.

1 . A capsule-type medical apparatus, comprising 
 a capsule-shape sealed container accommodating an electric component for executing a predetermined function; and    a switch unit arranged in a substantially center of the sealed container, and controlling supply of electric power for driving the electric component according to action of a magnetic field from outside of the sealed container.    
     
     
         2 . The capsule-type medical apparatus according to  claim 1 , wherein the switch unit is arranged on a central axis line in a lengthwise direction of the sealed container.  
     
     
         3 . The capsule-type medical apparatus according to  claim 1 , wherein 
 the sealed container is formed in a rotational symmetry shape, and    the switch unit is arranged on a central axis line of the rotational symmetry.    
     
     
         4 . The capsule-type medical apparatus according to  claim 1 , wherein 
 the sealed container is formed in a mirror-image symmetry shape, and    the switch unit is arranged in a mirror-image symmetry plane.    
     
     
         5 . A capsule-type medical apparatus, comprising: 
 a capsule-shape sealed container having a center axis and an outline of the sealed container formed in a rotational symmetry shape with respect to the center axis, the sealed container being introduced into a subject while accommodating an internal component for executing a predetermined function; and    an orientation recognizing unit indicating an accommodation direction about the center axis of the internal component with respect to the sealed container.    
     
     
         6 . The capsule-type medical apparatus according to  claim 5 , wherein the orientation recognizing unit is provided inside the sealed container while being visible from outside of the sealed container through a transparent portion constituting the sealed container.  
     
     
         7 . The capsule-type medical apparatus according to  claim 5 , wherein 
 the internal component includes an illumination board in which an emitter constituting an illumination unit is provided, the illumination unit emitting an illumination light outside the sealed container through the transparent portion constituting the sealed container, and    the orientation recognizing unit is provided on the illumination board while being visible from the outside of the sealed container through the transparent portion.    
     
     
         8 . The capsule-type medical apparatus according to  claim 7 , wherein 
 the illumination board is disk-shaped to be accommodated in the sealed container,    a flexible board electrically connecting the illumination board and another board is extends integrally with the illumination board, and    the orientation recognizing unit has a flat portion which is provided in the illumination board in order to fold the extended portion of the flexible board.    
     
     
         9 . The capsule-type medical apparatus according to  claim 5 , wherein the orientation recognizing unit indicates deviation of a center of gravity in a state in which the internal component is accommodated in the sealed container.  
     
     
         10 . The capsule-type medical apparatus according to  claim 5 , wherein 
 the internal component includes an imaging unit which images an inside of a subject through the transparent portion constituting the sealed container, and    the accommodation direction of the internal component is a vertical direction of the image taken by the imaging unit.    
     
     
         11 . The capsule-type medical apparatus according to  claim 5 , wherein 
 the internal component includes a reed switch which turns on and off a power supply, and    the accommodation direction of the internal component is a direction of an action magnetic field in the reed switch.    
     
     
         12 . The capsule-type medical apparatus according to  claim 5 , wherein 
 the internal component includes an antenna which has directivity in a predetermined direction in order to perform transmission and reception with outside of the sealed container, and    the accommodation direction of the internal component is a direction indicating the directivity in the antenna.
