Description
本発明は、栄養剤注入用器具とのコネクタを保持することが可能な外部バンパを有する瘻カテーテルに関するものである。 The present invention relates to a hemorrhoid catheter having an external bumper capable of holding a connector with a nutrient solution injection device.
口から食事を摂取できない患者は、例えば胃瘻チューブを介して栄養補給することが多く見られる。胃瘻チューブは、通常、胃と体外をつなぎ、抜けないように内部バンパ（胃内）と外部バンパ（体外）で止める機構を有している。 Patients who cannot take their meals by mouth are often fed for example via gastrostomy tubes. The gastrostomy tube usually has a mechanism that connects the stomach and the outside of the body and stops them with an internal bumper (inside the stomach) and an external bumper (outside the body) so as not to come off.
胃瘻チューブの外部バンパには、大きく分けて「ボタン型」と「チューブ型」の２種類がある（「ボタン型」、「チューブ型」の外部バンパを有する胃瘻カテーテルの構造の例を、それぞれ図１、２に示した。）。 There are two types of external bumpers for gastrostomy tubes: “button type” and “tube type” (examples of gastrostomy catheter structures with “button type” and “tube type” external bumpers, These are shown in FIGS.
ボタン型の長所は、目立たず日常動作の邪魔にならないので患者のＱＯＬ（クオリティーオブライフ）に貢献する。一方、短所は、指先でボタンを開閉し難いこと、栄養チューブとの接続がし難いこと、さらに栄養剤の流路が狭いことである。 The advantages of the button type are not conspicuous and do not interfere with daily operations, contributing to the patient's quality of life (QOL). On the other hand, the disadvantages are that it is difficult to open and close the button with the fingertip, it is difficult to connect to the nutrition tube, and the flow path of the nutrient is narrow.
これに対しチューブ型の長所は、栄養チューブとの接続が容易であることである。短所は、チューブが長いためチューブ内の感染が起き易いこと、体外に露出したチューブが邪魔になり事故抜去（引張って又は、引っ掛って抜ける）し易いことである。このように、ボタン型、チューブ型ともに改善の余地があることがわかる。 On the other hand, the advantage of the tube type is that it can be easily connected to the feeding tube. Disadvantages are that the tube is long, and infection within the tube is likely to occur, and the tube exposed outside the body is obstructive and easily removed (pulled or pulled out). Thus, it can be seen that there is room for improvement in both the button type and the tube type.
そこで、本発明は、上記の問題点を改善するものであって、栄養剤注入用器具との接続が容易で、更に栄養剤注入速度が高く、なお且つ日常動作の邪魔になり難い瘻カテーテルを提供することを目的とする。 Therefore, the present invention is to improve the above-mentioned problems, and is a sputum catheter that can be easily connected to a nutrient solution injection device, has a high nutrient solution injection speed, and does not easily interfere with daily operations.

These drawings are female connectors, and in particular, FIG. 5 shows a state before storage to which a male connector can be connected, and FIG. 6 shows a state after storage. 5 and 6 have a structure in which the connector is accommodated in parallel with the insertion axis of the hemorrhoid catheter (in this case, considering the thickness of the external bumper, the connector or the connector In the case of having a tube between the external bumpers, it is desirable to form the tube so that it fits in. From such a viewpoint, it is preferable that the connector is directly provided on the external bumper, and the connector is further connected to the external bumper. 5 and 6 show an example in which the connector is directly provided in the storage part of the external bumper.) Separately from this, the insertion axis of the hemorrhoid catheter It is also possible to adopt a structure in which the connector is stored in the direction of about 90 ° (here, about 90 ° is arranged so that the side surface of the connector is along the proximal surface (top surface) of the external bumper). Is In the case of fixing in this way, it is easy to reduce the protrusion from the top surface of the external bumper. Similarly, the connector is preferably provided directly on the external bumper, and the connector is preferably provided directly on the housing portion of the external bumper.
一方、図５、６の例では、コネクタはテーパー部品が組み上げられて形成される構造をしており、その中でも特にテーパー部品の角がオス側と嵌合する際に同心円状リブの役割を担う構造とされている（これとは別に、コネクタをコイル状に形成することで、らせん状のリブを得ることも可能である。但し、これらリブは必ずしもコネクタの伸縮構造に基づいたものである必要はなく、別途設けることも可能である。一方、段差をなくし、単純なテーパー状とすることも可能である。）。また、このテーパー部品はスライドして組み上げられた後に、回転させることでロックでき、テーパー形状を保持できる構造とすることが更に好ましい。尚、収納状態からオス側コネクタとの嵌合状態とする手順としては、図５のように組み立ててからオス側コネクタを挿入する方法と、図６の状態からキャップ２６を取り除いた後に、先ずオス側コネクタを差し込み、そのオス側コネクタに沿ってコネクタを引き出す方法が可能である。なお、図５で取っ手２４として示した様に、手で引き出しやすい構造を備えていることが好ましい。尚、図６に示した様に、収納時は外部バンパから図面上の上部に大きくはみ出さないようにコンパクトになることが好ましい（図５、６では、スライドして伸縮する構造が示されているが、この他にも例えば蛇腹構造とすることも可能である。）。 On the other hand, in the examples of FIGS. 5 and 6, the connector has a structure formed by assembling a tapered part, and among them, particularly when the corner of the tapered part is fitted to the male side, it plays a role of a concentric rib. (In addition to this, it is also possible to obtain a spiral rib by forming the connector in a coil shape. However, these ribs need not necessarily be based on the elastic structure of the connector. However, it is also possible to provide a separate taper without a step.) Further, it is more preferable that the taper part is structured such that it can be locked by being rotated after being slid and assembled, and the taper shape can be maintained. In addition, as a procedure to make a fitting state with a male side connector from an accommodation state, after removing the cap 26 from the method of inserting a male side connector after assembling as shown in FIG. A method of inserting the side connector and pulling out the connector along the male side connector is possible. In addition, as shown as the handle 24 in FIG. 5, it is preferable to have a structure that can be easily pulled out by hand. In addition, as shown in FIG. 6, it is preferable to be compact so that it does not protrude largely from the external bumper to the upper part of the drawing when stored (FIGS. 5 and 6 show a structure that slides and expands and contracts. However, other than this, for example, a bellows structure is also possible.)
第２の例として、コネクタを保持する機構が、外部バンパに設けられた固定治具である構造について説明する。当該構造の例として図７に（ａ）、（ｂ）として２例を示した。これらの図は共に瘻カテーテルの挿入軸に対し略９０°の方向に前記コネクタを向けて固定する構造であるが（固定治具を設ける構造では、特にコネクタ、或いはその根元や間に介するチューブを曲げて固定することとなり易く、コネクタの外部バンパ天面からの出っ張りを低減することが容易な点で挿入軸に対し略９０°の方向に固定することが好ましい。）、これとは異なり瘻カテーテルの挿入軸に対し平行にコネクタが固定される構造とすることも可能である。尚、この固定冶具としては、コネクタとの嵌合構造有するものが使用できる。この固定治具のホルダーとしては、各種方法を採用することが可能であるが、１ヶ又は複数のコネクタを引掛ける為のフック状のものを配置する方法や、外部バンパとコネクタの両方に磁石を配置、或いは一方に磁石、他方に磁性材料（例えば鉄など）を配置し、磁力を使って固定するもの、或いはマジックテープ（登録商標）を利用する方法などが挙げられる。尚、図７（ｂ）に示した様に、更に磁石移動領域（固定解除位置）の様な、固定を解除する手段、或いは固定されない状態を保持することが可能な手段が設けられていることが、更に好ましい。 As a second example, a structure in which the mechanism for holding the connector is a fixing jig provided in the external bumper will be described. As examples of the structure, two examples are shown in FIGS. 7A and 7B. Both of these figures show a structure in which the connector is fixed in a direction of approximately 90 ° with respect to the insertion axis of the hemorrhoid catheter (in the structure in which a fixing jig is provided, in particular, the connector or a tube interposed between the base and the middle thereof). Unlike the above, it is preferable to fix it in the direction of about 90 ° with respect to the insertion axis because it is easy to bend and fix and it is easy to reduce the protrusion of the connector from the top of the outer bumper. It is also possible to adopt a structure in which the connector is fixed in parallel to the insertion axis. In addition, as this fixing jig, what has a fitting structure with a connector can be used. Various methods can be used as a holder for the fixing jig, such as a method of arranging a hook-like one for hooking one or a plurality of connectors, or a magnet for both the external bumper and the connector. Or a magnet on one side and a magnetic material (such as iron) on the other and fixed using magnetic force, or a method using Velcro (registered trademark). In addition, as shown in FIG. 7B, there are further provided means for releasing the fixing, such as a magnet movement region (fixing release position), or a means capable of holding the unfixed state. Is more preferable.
これらの方法によれば、コネクタを外部バンパにコンパクトに保持することが可能であり、患者のＱＯＬに貢献する。更に、カテーテルテーパーなどの接続部を有する栄養剤注入用器具との接続においても容易に操作でき、比較的大きな流路を確保することができ、十分に栄養剤等の流量を確保することができる。 According to these methods, the connector can be held compactly by the external bumper, which contributes to the patient's QOL. Furthermore, it can be easily operated in connection with a nutrient solution infusion device having a connection portion such as a catheter taper, a relatively large flow path can be secured, and a sufficient flow rate of the nutrient solution or the like can be secured. .
