Embodiment Construction

[0070] Next, a first embodiment of the present invention will be described with reference to FIGS. 1 to 26 . FIG. 1 shows a schematic configuration of an entire endoscope system incorporating a balloon control device 1 which is a medical device according to the present embodiment.

[0071] In FIGS. 1 and 2 , reference numeral 2 is an endoscope, and 3 is an overtube as an insertion tool that assists insertion of the endoscope 2 . The endoscope 2 has an elongated insertion portion 4 for insertion into a body cavity. The insertion part 4 has: a hard distal end rigid part 5 ; a bending part 6 for bending; and a long and flexible flexible tube part 7 . The insertion portion 4 is formed by sequentially connecting the distal end rigid portion 5 , the bent portion 6 , and the flexible tube portion 7 from the distal end side.

[0072] The base end portion of the insertion portion 4 is connected to an operation portion 8 that is gripped and operated by an operator. A bending operatio...

Abstract

Main characteristic of the invention is to provide a medical instrument which can properly recover liquid even in case that the body fluid reversely flows into the feed / discharge tube, and can prohibit increasing of the manufacturing cost. In a case where a balloon is broken and a body fluid reversely flows into a feed / discharge tube during a suction operation of a balloon control apparatus, a pump is stopped by operation-canceling section after passing of a preset predetermined time, 20 seconds for example, and the suction operation of sucking the fluid into a bottle is canceled. Thereby, the amount of recovered liquid in the bottle is limited within a predetermined capacity. Thus, even in the case where the body fluid reversely flows into the feed / discharge tube, the body fluid does not overflow from the bottle, and the body liquid can properly recovered in the bottle.

Description

technical field [0001] The present invention relates to a medical device that supplies and exhausts air to a balloon mounted on a medical instrument such as an insertion tool for assisting the insertion of an endoscope into a body cavity, and has a built-in device for inflating and deflecting the balloon. stressors used. Background technique [0002] In general, when inserting an insertion portion of an endoscope into a deep luminal organ in the body such as the small intestine, an insertion tool that assists the insertion of the insertion portion is used. Patent Document 1 discloses an overtube as an insertion tool. The insertion portion of the endoscope is inserted through the overtube freely. Balloons are respectively attached to the distal end of the overtube and the distal end of the insertion portion of the endoscope. Air is supplied and exhausted to the balloon at the distal end of the overtube and the balloon at the distal end of the insertion portion of the endos...
