Description
【０００１】[0001]
この考案は，医療器具である中心静脈カテーテルを鎖骨下挿入するときの補助 具としてのものであり，カテーテルの他静脈への迷入を防いで中心静脈すなわち 上大静脈に入りやすく方向誘導することを目的とした，中心静脈カテーテル挿入 用の湾曲型外筒に関するものである． This device is an aid for inserting a central venous catheter, which is a medical device, into the subclavian region, and it is possible to prevent the catheter from getting into the other vein and easily guide it in the central vein, that is, the superior vena cava. The objective is a curved outer tube for inserting a central venous catheter.
【０００２】[0002]
従来の手技によって中心静脈カテーテルを鎖骨下から挿入する場合，まず，ま っすぐな外筒をかぶせた金属製の内筒針で鎖骨下静脈を穿刺し，内筒針を除去し た後，まっすぐな外筒を通じて，鎖骨下静脈から中心静脈までカテーテルを挿入 していたが，方向を正確に誘導するためにはＸ線透視やガイドワイヤーが必要で あり，盲目的な挿入では内頸静脈に迷入することがあり，その場合は再挿入しな ければならなかった． When inserting a central venous catheter through the subclavian region by the conventional technique, first, a subclavian vein is punctured with a metal inner tubular needle covered with a straight outer tube, the inner tubular needle is removed, and then the straight outer tube is removed. A catheter was inserted through the tube from the subclavian vein to the central vein, but fluoroscopy and a guide wire are needed to guide the direction accurately, and blind insertion may lead to the internal jugular vein. , And in that case we had to reinsert it.

本案は，Ｘ線透視が使用しにくいベッドサイドなどにおいて，またガイドワイ ヤーなしでも，中心静脈カテーテルの内頸静脈への迷入を防ぎ，できるだけ正確 に中心静脈に挿入できることを目的とした，中心静脈カテーテル挿入用の湾曲型 外筒を提供するものである． This plan aims to prevent the central venous catheter from entering the internal jugular vein and to insert it into the central vein as accurately as possible, even at the bedside where fluoroscopy is difficult to use, and even without a guide wire. A curved outer tube for inserting a catheter is provided.

いまその解決手段を図面に追いながら説明する． Now, I will explain the solution by following the drawings.
【０００５】 請求項１については，図１のごとく，鎖骨下捜入用の中心静脈カテーテル１を 容易に通す内径をもち，その先端寄りの部分に鈍角的な湾曲２を設けた，中心静 脈カテーテル挿入用の湾曲型外筒３である．According to the first aspect of the present invention, as shown in FIG. 1, a central vein having an inner diameter through which a central venous catheter 1 for subclavian retrieval can be easily passed, and an obtuse curve 2 is provided in a portion near the tip thereof. A curved outer cylinder 3 for inserting a catheter.
【０００６】 請求項２については，図２のごとく，請求項１の湾曲型外筒３に，湾曲方向を 示す印４をつけたものである．According to the second aspect, as shown in FIG. 2, the curved outer cylinder 3 of the first aspect is provided with a mark 4 indicating the bending direction.
【０００７】 請求項３については，図３および図４のごとく，請求項１の湾曲型外筒３に， その全長にわたって長軸方向に空隙５を設けたものである．According to the third aspect, as shown in FIGS. 3 and 4, the curved outer cylinder 3 of the first aspect is provided with a gap 5 in the major axis direction over the entire length thereof.
【０００８】[0008]
中心静脈カテーテル１を，鎖骨下静脈まで一般的手技で挿入したのち，図５の ごとくあらかじめ中心静脈カテーテル１の手元部分にかぶせておいた湾曲型外筒 ３を，中心静脈カテーテル１に沿わせて，かつ湾曲の小湾側を***側に向けて挿 入していけば，湾曲型外筒３は中心静脈７に向かうこととなり，図６のごとく， その湾曲型外筒３を介して中心静脈カテーテル１をさらに進めていけば，頭側に 分岐する内頸静脈８へ迷入する可能性は少なく，目的通りに中心静脈７に到達す る確率が高くなる． After inserting the central venous catheter 1 to the subclavian vein by a general procedure, put the curved outer tube 3 that was previously covered on the proximal part of the central venous catheter 1 along the central venous catheter 1 as shown in FIG. If the small side of the curve is inserted toward the breast side, the curved outer tube 3 will face the central vein 7, and as shown in FIG. If the catheter 1 is advanced further, it is less likely to get into the internal jugular vein 8 branching to the head side, and the probability of reaching the central vein 7 as intended increases.
【０００９】 請求項２においては，湾曲型外筒３の湾曲方向を示す印４を***側に向けて挿 入することによって，湾曲型外筒３が中心静脈７に向かっていることを確認でき る．According to the second aspect, by inserting the mark 4 indicating the bending direction of the curved outer cylinder 3 toward the breast side, it can be confirmed that the curved outer cylinder 3 is directed toward the central vein 7. The
【００１０】 請求項３においては，湾曲型外筒３の空隙５を有する面を***側に向けて挿入 することによって，湾曲型外筒３が中心静脈７に向かっていることを確認できる ．According to the third aspect, it is possible to confirm that the curved outer cylinder 3 is directed toward the central vein 7 by inserting the surface of the curved outer cylinder 3 having the void 5 toward the breast side.
【００１１】 請求項３においては，図４に示すごとく，湾曲型外筒の下面に設けた空隙５に よって，湾曲型外筒３の中心静脈カテーテルからの着脱が可能になる．According to the third aspect, as shown in FIG. 4, the curved outer cylinder 3 can be attached to and detached from the central venous catheter by the space 5 provided in the lower surface of the curved outer cylinder.
【００１２】[0012]
以下，実施例について，さらに詳細に説明する． Hereinafter, examples will be described in more detail.
【００１３】 請求項１，請求項２および請求項３の湾曲型外筒３は，中心静脈カテーテル１ を容易に通す内径をもつことが必要であるが，鎖骨下の皮下組織や静脈壁を通す うえで，適度な外径とし，湾曲角度も鈍角的なものとする．The curved outer cylinder 3 of claims 1, 2 and 3 is required to have an inner diameter through which the central venous catheter 1 can be easily passed, but through the subclavian subcutaneous tissue and vein wall. In addition, the outer diameter is moderate and the bending angle is obtuse.
【００１４】 図２に示す請求項２での湾曲方向を示す印４は，湾曲型外筒の手元の部分につ ける必要があるが，全長にわたってつけてもよい．The mark 4 indicating the bending direction in claim 2 shown in FIG. 2 is required to be provided at the proximal portion of the curved outer cylinder, but may be provided over the entire length.
【００１５】 図３，図４に示す請求項３での空隙５は，湾曲型外筒３の形状が崩れない程度 で，なおかつ中心静脈カテーテル１からの着脱が可能な空隙幅とする．The gap 5 in claim 3 shown in FIGS. 3 and 4 has such a width that the shape of the curved outer cylinder 3 is not collapsed and that it can be attached to and detached from the central venous catheter 1.
【００１６】[0016]
以上のように，本考案の中心静脈カテーテル挿入用の湾曲型外筒を用いれば， 中心静脈カテーテル挿入操作において，Ｘ線透視やガイドワイヤーの使用なしで も，カテーテルは内頸静脈へ迷入することは少なく，目的どおりに中心静脈に挿 入されやすくなる． As described above, with the use of the curved outer tube for inserting the central venous catheter of the present invention, the catheter can enter the internal jugular vein during the central venous catheter insertion operation without the use of fluoroscopy or a guide wire. There are few, and it is easy to insert into the central vein as intended.
