【産業上の利用分野】本考案は、食道、胃並びに食道及び胃静脈瘤等を圧迫止血に主として用いるバルーンカテーテルの改良に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a balloon catheter mainly used for compression hemostasis of the esophagus, stomach, esophagus and gastric varices.

【０００２】[0002]

【従来の技術】従来から静脈瘤等の止血手段として、該患部をカテーテルに設けたバルーンをもって圧迫する治療が行われている。この種のカテーテルは、体内挿脱により組織を傷めないよう、シリコーンゴム、塩化ビニール樹脂等のようにできるだけ柔軟性に富む材質が用いられる。しかしながら、該カテーテルが柔軟であるために、例えば、患者の鼻腔からカテーテルを挿入しようとするとき、その挿入に困難を来すことになる。しかも、静脈瘤の止血治療を要する場合は、殆どの症例において緊急治療が求められているのであり、患者の多くはショック状態にあるか、錯乱状態に陥っているから、より挿入を困難にする条件下に施術せざるを得ず、その挿入に要する時間も著しく長くかかるのが一般であった。2. Description of the Related Art Conventionally, as a hemostatic means for varicose veins, a treatment of pressing the affected area with a balloon provided on a catheter has been performed. This type of catheter is made of a material that is as flexible as possible, such as silicone rubber or vinyl chloride resin, so as not to damage the tissue when it is inserted into or removed from the body. However, the flexibility of the catheter makes it difficult to insert, for example, when attempting to insert the catheter through the nasal cavity of a patient. Moreover, when hemostatic treatment of varicose veins is required, urgent treatment is required in most cases, and most patients are in a shock state or are in a confusion state, which makes insertion more difficult. In general, the operation had to be performed under certain conditions, and the time required for insertion was generally extremely long.

【考案が解決しようとする課題】本考案は、前記施術にあたり、患者の苦痛の軽減及びカテーテル挿入に要する時間の短縮化並びに施術の簡易化を目的とした止血用カテーテルを提供するにある。DISCLOSURE OF INVENTION Problem to be Solved by the Invention The present invention provides a hemostasis catheter for the purpose of reducing the pain of the patient, shortening the time required for catheter insertion, and simplifying the operation. .

【０００４】[0004]

【課題を解決するための技術手段】前記課題を解決するため、本考案においては、カテーテルチューブの先端部に食道内容物吸引孔、胃内容物吸引孔、止血圧迫用（単数又は複数の）バルーンを備え、食道、胃内容物の吸引及び単数又は複数の患部止血圧迫を可能とするとともに、カテーテルチューブに滑性材コーティング層を設けてスムースにスタイレットを挿着してカテーテルの人体内挿入を容易にできるようにし、併せてスタイレット抜去後は前記吸引に用いる医療機器をその都度脱着を繰り返す手間を省き、該医療機器装着のまま体内に生理食塩水や薬剤を注入可能とするため、分岐管状にしたコネクターを付設したカテーテルに構成した。[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, an esophageal contents suction hole, a stomach contents suction hole, a hemostasis (single or plural) ) A balloon is provided to allow suction of the esophagus, stomach contents and hemostasis of one or more affected areas, and a catheter tube is provided with a lubricant coating layer and a stylet is inserted smoothly to attach the catheter. It is possible to easily insert the medical instrument into the human body, and after removing the stylet, eliminate the need to repeatedly attach and detach the medical device used for the suction each time. In order to make it possible to inject blood, a catheter with a branched tubular connector was configured.
