Abstract

<P>PROBLEM TO BE SOLVED: To provide an instrument preventing air sent into the stomach from flowing to the duodenum, causing no satiety, retaining the intragastric pressure constant and enabling to quickly and precisely perform an endoscopic treatment. <P>SOLUTION: This catheter is produced by attaching two balloons to a part near its distal end and forming side holes on their back sides, its proximal end is put into a liquid to measure the pressure. This constitution can prevent the air sent into the stomach from flowing into the duodenum and retain the intragastric pressure constant. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

発明の詳細な説明Detailed Description of the Invention

医療分野。内視鏡分野。Medical field. Endoscopy field.

簡便に胃内圧を一定に保つためのカテーテルは存在しなかった。There was no catheter for easily keeping the gastric pressure constant.

発明が解決しようとする課題Problems to be solved by the invention

近年、内視鏡的治療は急速に発展しつつある。それに伴い手術ではなく、内視鏡により切除される胃癌も増加しつつある。
しかし高度な技術を要するため内視鏡的治療における検査、治療時間は長く、数時間に及ぶこともある。患者にとっては内視鏡的治療という低侵襲な治療を受けられ利益がある反面、長時間に及ぶ内視鏡検査、治療により腸管内に多量の空気が送り込まれ、腹満感、嘔気など極めて不快な症状が現れるといった不利な点が残っている。また腹満感、嘔気による患者の体動のため内視鏡的治療を迅速かつ正確に施行することが不可能になることもある。In recent years, endoscopic treatment has been developing rapidly. Along with this, gastric cancer that is removed not by surgery but by endoscope is also increasing.
However, since advanced techniques are required, the examination and treatment time in the endoscopic treatment is long, and it may take several hours. Although it is beneficial for patients to receive a minimally invasive treatment such as endoscopic treatment, a long amount of endoscopic examination and treatment sends a large amount of air into the intestinal tract, which is extremely uncomfortable, such as fullness and nausea. Disadvantages remain, such as the appearance of various symptoms. In addition, the patient's body movement due to fullness and nausea may make it impossible to perform endoscopic treatment quickly and accurately.

課題を解決するための手段Means for solving the problem

胃内に送り込まれた空気が十二指腸に流れるのを防止し、腹満感を発症させず、かつ胃内の圧を一定に保ち、内視鏡的治療を迅速かつ正確に施行することを可能にする器具を発明する。  Prevents the air sent into the stomach from flowing into the duodenum, does not cause a feeling of fullness, maintains a constant pressure in the stomach, and enables endoscopic treatment to be performed quickly and accurately Invent an instrument to do.

先端付近に２つのバルーンが取り付けられ、その後側に側孔があり、末端が液体の中に入れられ圧を計測できるカテーテルを作る。これにより胃内に送り込まれた空気が十二指腸に流れるのを防止し、かつ胃内の圧を一定に保つことが可能になる。またカテーテル先端付近に径の小さい輪を取り付けることにより、この輪を内視鏡器具で把持し容易にカテーテル先端を十二指腸に誘導できる。  Two balloons are attached near the tip, and there is a side hole on the back side, and the end is placed in a liquid to make a catheter that can measure pressure. As a result, air sent into the stomach can be prevented from flowing into the duodenum, and the pressure in the stomach can be kept constant. Further, by attaching a ring with a small diameter in the vicinity of the catheter tip, the tip of the catheter can be easily guided to the duodenum by grasping the ring with an endoscopic instrument.

発明の効果The invention's effect

胃内に送り込まれた空気が十二指腸に流れるのを防止し、腹満感を発症させず、かつ胃内の圧を一定に保ち、内視鏡的治療を迅速かつ正確に施行することを可能にする。また、内視鏡検査中に胃内圧を簡便に計測することが可能となり、胃の病変がどれくらいの胃内圧で観察されたものか客観的に記録することも可能となり診断学の発展に貢献できるものと確信する。Prevents the air sent into the stomach from flowing into the duodenum, does not cause a feeling of fullness, maintains a constant pressure in the stomach, and enables endoscopic treatment to be performed quickly and accurately To do. In addition, gastric pressure can be easily measured during endoscopy, and it is possible to objectively record how much gastric lesions are observed at what gastric pressure, contributing to the development of diagnostics. I'm sure.
