Description
【考案の詳細な説明】
本考案は医療用カテーテルに関するものである３人体の
液体管内に医療用、カテーテル（以下カテーテルと称す
る）を挿入して種々様々な治療を試みられているが、肉
眼ではそのカテーテルが正確に患部へ到達したかを見分
けることはできない。[Detailed description of the invention] This invention relates to medical catheters.3 Various treatments have been attempted by inserting medical catheters (hereinafter referred to as catheters) into the liquid canals of the human body, but they cannot be seen with the naked eye. It is impossible to tell whether the catheter has accurately reached the affected area.
従来は、予じめ患部までの長さを予測してそのカテーテ
ルを挿入するか又はカテーテルの材質にＸ線造影剤を混
入させたカテーテル又はカテーテル管内にＸ線造影剤を
注入等をしてＸ線照射しながら患部へ到着させている。Conventionally, the length to the affected area was predicted in advance and the catheter was inserted, or the material of the catheter was mixed with an X-ray contrast agent or an X-ray contrast agent was injected into the catheter tube. The beam is delivered to the affected area while irradiating it.
これらの場合はＸ線装置がないと正確にカテーテルが患
部に到着したかを知ることが出来ない。In these cases, without an X-ray device, it is impossible to accurately determine whether the catheter has arrived at the affected area.
そこでかがる不便さを解消して、Ｘ線装置を持込まなく
ても、容易にカテーテルが必要とする部位へ到着したか
を知ることが出来るカテーテルを提供するものである。The object of the present invention is to provide a catheter that eliminates this inconvenience and allows one to easily determine whether the catheter has arrived at the required site without bringing in an X-ray device.
以下本考案の一実施例の図面によって詳細に説明をする
。An embodiment of the present invention will be described in detail below with reference to the drawings.
第１図は従来のカテーテルの先端部分の側面断面図であ
る。FIG. 1 is a side sectional view of the distal end portion of a conventional catheter.
カテーテル１の中にＸ線造影剤２を混入させであるので
Ｘ線を照射すればカテーテル１は造影される。Since the X-ray contrast agent 2 is mixed into the catheter 1, the catheter 1 is contrasted when X-rays are irradiated.
３は薬液等の流出入口である。3 is an inlet for the inflow and outflow of chemical solutions, etc.
第２図は本考案の一実施例でカテーテル１′の先端部に
極めて小型の放電型電球４を設けて電球４の給電用導線
５及び５′をカテーテル１の側壁内部に埋設しである。FIG. 2 shows an embodiment of the present invention, in which an extremely small discharge type light bulb 4 is provided at the distal end of a catheter 1', and power supply conductors 5 and 5' of the light bulb 4 are buried inside the side wall of the catheter 1.
通常のタングステンフィラメント通電型の極小電球では
光量が少ないためカテーテル１′の先端に取付は使用し
ても充分な効果は得られないので電位の高い電気を使用
して放電型電球を閃光させてカテーテル１′が必要とす
る部位へ到着したかを知ることができる。A normal tungsten filament energized miniature light bulb does not provide sufficient light even if it is attached to the tip of the catheter 1' due to its low light intensity. It is possible to know whether 1' has arrived at the required site.
カテーテル１′ 自体は高分子樹脂であるので使用する
電気に対しては充分に電気絶縁性を有しているので感電
の心配はない。Since the catheter 1' itself is made of polymer resin, it has sufficient electrical insulation properties against the electricity used, so there is no fear of electric shock.
更にまた使用する電気は、極めて小さな該電球４を使用
しているので、必要とする電力は微弱である。Furthermore, since the extremely small light bulb 4 is used, the power required is very weak.
第３図は第２図Ａ−Ａ部分の断面図である。FIG. 3 is a sectional view taken along line A-A in FIG.
電球４の陰極５ａには導線５、陽極５ｂには導線５′を
接続しである。A conducting wire 5 is connected to the cathode 5a of the light bulb 4, and a conducting wire 5' is connected to the anode 5b.
電球４は閃光させるための放電型電球であるので、内部
には閃光の光量を大きくするための特定物質が含まれて
いることは当然である。Since the light bulb 4 is a discharge type light bulb for producing flash light, it is natural that the inside thereof contains a specific substance for increasing the amount of light produced by flash light.
以上述べた様に、本考案の実施によればＸ線装置等を使
用しなくてもカテーテル１′の先端に有する放電型電球
４の閃光で、必要とする挿入部位にカテーテル１′が到
着したかを知ることが出来る等の特徴を有している。As described above, according to the implementation of the present invention, the catheter 1' can arrive at the required insertion site by the flash of the discharge type light bulb 4 provided at the tip of the catheter 1' without using an X-ray device or the like. It has characteristics such as being able to know what is going on.
