Airbag type endoscope

Abstract

A warning unit outputs an alert when a first abnormality detector and a second abnormality detector determine detachment or loosening of a tube (110) that can cause abnormal pressure in each balloon (20,54).

Description

technical field [0001] The present invention relates to an airbag type endoscope, in particular to an endoscope with a freely expandable airbag provided at the front end of the endoscope insertion part. In addition, the present invention relates to a balloon control device for a double-balloon endoscope capable of improving safety when using the double-balloon endoscope. Background technique [0002] A double-balloon endoscope is known as a device to replace the conventional small intestine endoscope. This double-balloon endoscope is composed of an endoscope with an air bag at the front end of the endoscope that can supply and suck air to the air bag, and a cannula as an insertion part that can be inserted into the endoscope. An airbag is provided and a cannula is configured to supply and suck air to and from the airbag (for example, Japanese Patent Application Laid-Open No. 51-11689 (page 2, FIG. 1 )). [0003] The air bag control device is connected to each air bag of th...

AI Technical Summary

Problems solved by technology

The set pressure when the balloon is fixed to the intestinal wall is set to a certain pressure suitable for the human intestine, but in the case of the large intestine with a large lumen diameter, the size of the balloon reaches the lumen but the pressure But it can't rise to the problem of setting pressure

[0010] Moreover, when connecting the air supply and suction tubes to the air bag air inlets of the balloon endoscope and the cannula, it is possible to connect the tubes incorrectly.
