Claims (9)

In a capsule medical device that performs inspection, treatment, or treatment in the body cavity of a human or animal,
A capsule body;
A magnetic switch built into the capsule body,
A plurality of electrical circuits built in the capsule body and connected to the magnetic switch;
A magnet housing part that is formed in the capsule body at a position close to the magnetic switch and houses a magnet from the outside of the capsule body;
A magnet housed in the magnet housing section;
The capsule medical device is characterized in that when the magnet is housed in the magnet housing portion from the outside of the capsule body, the magnetic switch is turned on by the magnet to turn on the electric circuit . A female screw is provided on the inner periphery of the magnet housing portion formed on the capsule body, while a male screw is formed on the outer periphery on the magnet side to be screwed into the female screw, and the male screw on the magnet side is connected to the magnet housing portion. 2. The capsule medical device according to claim 1, wherein the capsule medical device is screwed into a female screw and stored in a magnet storage unit. 2. The capsule medical device according to claim 1, wherein the magnet can be housed and fixed by a fitting method in a magnet housing portion formed in the capsule body. The magnet housing part is formed at the rear part of the capsule body, and the attracting part of the collecting tool is attracted by the magnetic force of the magnet housed and fixed in the magnet housing part of the capsule body, and the capsule body is passed through the collecting tool. The capsule medical device according to any one of claims 1 to 3, wherein the medical device can be collected. A plurality of magnets having different weights are prepared, and one of them is selected and stored in the magnet storage chamber so that the specific gravity of the capsule body can be adjusted during use, and is placed in a body cavity. The capsule medical device according to any one of claims 1 to 3, wherein the specific gravity of the capsule body is substantially equal to a liquid and can be adjusted so as to be heavier or lighter. In a capsule medical device that performs inspection, treatment, or treatment in the body cavity of a human or animal
  A capsule body;
  A magnetic switch built in the capsule body in the axial direction of the capsule body;
  A plurality of electrical circuits built in the capsule body and connected to the magnetic switch;
  A magnet housing part formed in the axial direction of the capsule body along the magnetic switch from the position close to the outer periphery side of the magnetic switch to the rear,
  A magnet housed in the magnet housing part at a position on the rear side that is not close to the magnetic switch and that does not turn on the magnetic switch;
  Magnet pushing means for pushing and moving the magnet from outside to a position where the magnetic switch can be turned on;
  A capsule that includes: when the magnet is pushed and moved to a position where the magnetic switch is turned on by the magnet pushing means; and the magnetic switch is turned on by the magnet to turn on the electric circuit. Type medical device. In a capsule medical device that performs inspection, treatment, or treatment in the body cavity of a human or animal
  A capsule body;
  A power supply unit built into the capsule body,
  A plurality of electric circuits incorporated in the capsule body;
  A movable magnet switch that is movably disposed on the rear end side of the capsule body, has one end connected to the power supply unit, and the other end connected to the electric circuit,
  The capsule medical device is characterized in that the moving magnet switch is moved by external magnetism to conduct the power supply unit and the electric circuit. The moving magnet switch is a rotating magnet switch, and contacts the conductive part by rotating the disk-shaped magnet by the external magnetism, a conductive part provided around the magnet, and the disk-shaped magnet. The capsule medical device according to claim 7, further comprising: two contact points arranged in proximity to the periphery of the magnet to be conducted. The moving magnet switch is a slide magnet switch, and is electrically connected to the bar-shaped magnet, a conductive part provided on one side in the longitudinal direction of the magnet, and the bar-shaped magnet sliding by external magnetism. The capsule medical device according to claim 7, further comprising: two contact points arranged close to a sliding direction of the magnet to be moved.
