Abstract
Description
本発明は、カテーテル固定具に関するものである。 The present invention relates to a catheter fixture.
近年、経口から栄養を摂取できない患者に対する栄養の投与方法として、胃内へ経皮的に挿入された胃瘻用カテーテルから直接栄養を注入する栄養管理が多く行われている。 2. Description of the Related Art In recent years, as a method of administering nutrition to patients who cannot take nutrients orally, nutrition management in which nutrition is directly injected from a gastrostomy catheter inserted percutaneously into the stomach has been frequently performed.
経皮的に挿入される胃瘻用カテーテルには、カテーテルの挿入長さを規定すると共に体表部分にカテーテルを固定するカテーテル固定具が考案されている（例えば、特許文献１参照）。 For a gastrostomy catheter that is inserted percutaneously, a catheter fixture that regulates the insertion length of the catheter and fixes the catheter to the body surface has been devised (see, for example, Patent Document 1).
従来のカテーテル固定具は、一度カテーテルの挿入長さを決定し体表にカテーテルを固定すると、例えばカテーテルの挿入長さを変更したい場合、カテーテルとの摩擦が大きいために固定具を容易に移動することができないという問題点があった。
本発明は、必要な時には容易に移動できてカテーテルの挿入長さを簡単に変更できるカテーテル固定具を提供することにある。
In the conventional catheter fixture, once the insertion length of the catheter is determined and the catheter is fixed to the body surface, for example, when it is desired to change the insertion length of the catheter, the fixture is easily moved due to large friction with the catheter. There was a problem that it was not possible.
An object of the present invention is to provide a catheter fixture that can be easily moved when necessary and can easily change the insertion length of the catheter.
このような目的は、下記の本発明により達成される。
経皮的に体内へ挿入されるカテーテルの長さ方向に移動自在に嵌装され、該カテーテルを体表に固定するカテーテル固定具であって、
前記カテーテルの長さ方向への移動を制御して該カテーテルを所定の位置に固定する略円筒状のカテーテル固定部、体表に接して固定する略円盤状の体表固定部、及び前記カテーテル固定部の外側面と前記体表固定部の体表に接する面の反対面とが連結された複数のアーム、によって構成され、前記カテーテル固定部の全高（Ａ）と、前記カテーテル固定具の全高（Ｂ）との比率（Ａ）／（Ｂ）は、５／１０以上、９／１０以下であることを特徴とするカテーテル固定具。
Such an object is achieved by the present invention described below.
A catheter fixing tool that is movably fitted in the length direction of a catheter inserted percutaneously into the body, and fixes the catheter to the body surface,
A substantially cylindrical catheter fixing portion that controls movement of the catheter in the length direction to fix the catheter at a predetermined position, a substantially disc-shaped body surface fixing portion that contacts and fixes the body surface, and the catheter fixing A plurality of arms connected to an outer surface of the body and a surface opposite to the surface of the body surface fixing portion contacting the body surface, and the total height (A) of the catheter fixing portion and the total height of the catheter fixing device ( The ratio (A) / (B) to B) is 5/10 or more and 9/10 or less.
本発明によれば、必要な時には容易に移動できてカテーテルの挿入長さを簡単に変更できるカテーテル固定具を提供することができる。 According to the present invention, it is possible to provide a catheter fixture that can be easily moved when necessary and can easily change the insertion length of the catheter.
次に、本発明の好適な実施の形態におけるカテーテル固定具について図１〜図４を参照にして説明する。
図１はカテーテルにカテーテル固定具を取り付けた概略図、図２はカテーテル固定具の断面図、図３はカテーテル固定具をカテーテル上方へ移動させるときの断面図、図４はカテーテル固定具をカテーテル下方へ移動させるときの断面図である。ここで、カテーテル上方とはカテーテル基端部側への方向を意味し、カテーテル下方とはカテーテル先端部側への方向を意味する。
Next, a catheter fixture according to a preferred embodiment of the present invention will be described with reference to FIGS.
1 is a schematic view of a catheter fixture attached to a catheter, FIG. 2 is a sectional view of the catheter fixture, FIG. 3 is a sectional view when the catheter fixture is moved upward, and FIG. 4 is a view of the catheter fixture below the catheter. It is sectional drawing when making it move to. Here, “upper catheter” means a direction toward the proximal end portion of the catheter, and “lower catheter” means a direction toward the distal end portion of the catheter.
図１に示すように、本発明の好適な実施の形態におけるカテーテル固定具４０は、カテーテルの長さ方向への移動を制御して該カテーテルを所定の位置に固定する略円筒状のカテーテル固定部１０、体表に接して固定する略円盤状の体表固定部３０、及び前記カテーテル固定部の外側面と前記体表固定部の体表に接する面の反対面とが連結された複数のアームから構成されている。カテーテル固定具４０は、カテーテルに嵌装し、カテーテルの長さ方向へ自在に移動させて体表に固定することにより、所定の位置でカテーテルの挿入長さを規定するものである。 As shown in FIG. 1, a catheter fixing device 40 according to a preferred embodiment of the present invention is a substantially cylindrical catheter fixing portion that controls movement of the catheter in the length direction to fix the catheter at a predetermined position. 10. A substantially disk-shaped body surface fixing part 30 fixed in contact with the body surface, and a plurality of arms in which an outer surface of the catheter fixing part and an opposite surface of the body surface fixing part in contact with the body surface are connected It is composed of The catheter fixture 40 is inserted into the catheter, is moved freely in the length direction of the catheter, and is fixed to the body surface, thereby defining the insertion length of the catheter at a predetermined position.
カテーテル固定具４０は弾性材料で形成されることが好ましく、例えば、軟質塩化ビニル樹脂、ポリウレタン樹脂、シリコーンゴム等が挙げられるが、生体において組織反応性の少ないシリコーンゴムを好ましく用いることができる。カテーテル固定部１０、アーム２０、体表固定部３０が一体で形成されていてもよく、別部品として組み立ててもよい。 The catheter fixture 40 is preferably formed of an elastic material, and examples thereof include soft vinyl chloride resin, polyurethane resin, and silicone rubber. Silicone rubber having low tissue reactivity in a living body can be preferably used. The catheter fixing part 10, the arm 20, and the body surface fixing part 30 may be integrally formed, or may be assembled as separate parts.
図２に示すように、カテーテル固定部１０のカテーテル固定部底面１１が体表固定部３０の体表固定部底面３１よりも上方にあり、体表固定部３０のカテーテルが挿入されている体表部分を露出するように形成されている。このときのカテーテル固定部１０の全高（Ａ）とカテーテル固定具４０の全高（Ｂ）の比率（Ａ）／（Ｂ）は、５／１０以上、９／１０以下である。更に好ましくは、６／１０以上、８／１０以下である。比率（Ａ）／（Ｂ）を上記範囲とすることで体表部分にカテーテル固定部底面３１が接触することがないため、カテーテルが挿入されている体表部分にかかる負担を低減することができる。 As shown in FIG. 2, the body surface 11 on which the catheter fixing part bottom surface 11 of the catheter fixing part 10 is above the body surface fixing part bottom surface 31 of the body surface fixing part 30 and the catheter of the body surface fixing part 30 is inserted. It is formed so as to expose the part. The ratio (A) / (B) of the total height (A) of the catheter fixing part 10 and the total height (B) of the catheter fixture 40 at this time is 5/10 or more and 9/10 or less. More preferably, it is 6/10 or more and 8/10 or less. By setting the ratio (A) / (B) within the above range, the catheter fixing unit bottom surface 31 does not come into contact with the body surface portion, so the burden on the body surface portion where the catheter is inserted can be reduced. .
更に、比率（Ａ）／（Ｂ）を上記範囲とすることで、図３及び図４に示すように、カテーテル固定具４０をカテーテルに沿わせて移動させるときに、アーム２０を指で上方又は下方に変形させることが容易となり、カテーテル外面とカテーテル固定部１０の内腔面との接触面積が小さくなることで摩擦も小さくなり、カテーテル固定具の移動を容易なものとすることができる。また、カテーテル固定具４０を移動させた後にアーム２０の変形を解除することで、固定力は回復する。 Further, by setting the ratio (A) / (B) within the above range, as shown in FIGS. 3 and 4, when the catheter fixture 40 is moved along the catheter, the arm 20 is moved upward with a finger or It becomes easy to be deformed downward, and the contact area between the outer surface of the catheter and the lumen surface of the catheter fixing portion 10 is reduced, so that the friction is reduced and the movement of the catheter fixture can be facilitated. In addition, the fixing force is recovered by releasing the deformation of the arm 20 after moving the catheter fixture 40.
本発明の好適な実施の形態におけるカテーテル固定具によれば患者の体内臓器内へ経皮的にカテーテルを挿入し体表部分を固定するカテーテル固定具が通常はカテーテルに固定されているが、必要な時には容易に移動できるカテーテル固定具を提供することができる。 According to the catheter fixing tool in a preferred embodiment of the present invention, the catheter fixing tool for percutaneously inserting the catheter into the internal organ of the patient and fixing the body surface part is usually fixed to the catheter. It is possible to provide a catheter fixture that can be easily moved at times.
