Description

Automatic air pressure control device using an endoscope

The present invention relates to an apparatus for automatically adjusting air pressure using an endoscope, and more particularly, to an apparatus for automatically adjusting air pressure using an endoscope capable of appropriately adjusting air pressure in the upper gastrointestinal tract.

In general, an endoscope is a medical device that allows direct viewing of internal organs or body cavities. Through such an endoscope, it is possible to observe by inserting a machine into an organ that cannot directly confirm a lesion without surgery or an autopsy.

As a type of endoscope, it may be classified into a bronchoscope, a digestive endoscope, etc. according to an observation part. Among these, gastrointestinal endoscopy is used to inflate the lumen by injecting external air during the procedure and to inhale air, intestinal fluid, or excreta in the lumen to effectively observe the lesion in the organ, or to perform procedures such as biopsy.

The digestive endoscope is provided as a length member with a predetermined diameter so that it can smoothly enter and exit the digestive system. At the distal end of the digestive endoscope, there is a light source that emits light to the inspection site inside the lumen, a receiver that receives an image with the reflected light, and forceps serving as a passage to suck materials in the lumen or to supply substances such as air into the lumen Balls are provided.

However, when air pressure in an organ (eg, stomach) rises during an interventional procedure using a conventional digestive endoscope, due to a catheter and a medical device that entered the endoscopic insertion tube (working channel), the internal organs during the procedure There is a limit in which air suction cannot be properly performed.

For example, in order to discharge the air in the organ, the process of temporarily removing the catheter already inserted in the digestive endoscope, then discharging the air, and entering the catheter again must be repeated periodically. It causes inconvenience, and it is difficult to quickly perform an interventional procedure.
