Utility application filed earlier by the co-applicant of the present applicant in 1987-
As disclosed in No. 125913, a strong ferrite magnet or rare earth magnet is fixed to the insertion end of the tube body and inserted into the stomach, and a metal foreign object such as an alkaline battery is attracted to the magnet and then pulled out. A device that can be pulled out by a method has been proposed and put into practical use. However, with this type of device, foreign objects may get caught in narrow passages such as the cardia or pharynx, and frictional resistance may occur. This caused problems such as easy falling off from the magnet.
この考案は、上記した先願考案の欠点を解消す

The air supply hole opened on the circumferential side of side a,
A balloon body 6 made of rubber that can be expanded and contracted is encapsulated and sealed around the air supply hole 4 . Furthermore, numeral 7 in the figure is a check valve provided at the proximal opening 1b of the tube body 1, which can prevent the air a pressurized into the air supply cavity 5 from flowing backward.

By using the other cavity 52 as an airway and using the other cavity 52 as a drainage path, the liquid suction hole 52a communicating with the drainage path is opened on the insertion end 1a side of the tube body 1 where the balloon body 6 is provided. The device is constructed so that the fluid in the stomach can be discharged to the outside at the same time as the foreign object is pulled out.

を奏するものである。 As explained above, in this invention, a magnet is attached to the obstructed insertion end of a tube body inserted into the stomach, and when a foreign object is attracted and removed from the stomach by the magnet, the tube body is inserted into the stomach. Since the balloon body is provided adjacent to the magnet at the end and the balloon body is configured to maintain expansion when pulled out, the balloon body can easily expand narrow passages such as the cardia and pharynx. As a result, it is possible to prevent foreign objects attracted to the magnet from getting caught in narrow passages, and to smoothly take them out, resulting in excellent practical effects.
