Description
【考案の詳細な説明】 本発明は医療用カテーテルに関するものである。[Detailed explanation of the idea] The present invention relates to medical catheters.
人体の体液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着したかを
兄分けることはできない。Various treatments have been attempted by inserting medical catheters (hereinafter referred to as catheters) into the body's fluid ducts, but it is not possible to tell with the naked eye 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自体に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, X-rays were irradiated by predicting the length to the affected area in advance and inserting the catheter, or by injecting an X-ray contrast agent into the catheter or catheter tube with an X-ray contrast agent mixed into the catheter itself. While doing so, the patient is delivered to the affected area.
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 not possible to accurately determine whether the catheter has arrived at the affected area.
そこでかかる不便さを解決して、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。Therefore, it is an object of the present invention to provide a catheter that solves this inconvenience and allows the user to easily know 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。Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
第１図は従来のカテーテルの一実施例の先端部分の側面
断面図である。FIG. 1 is a side sectional view of the distal end portion of an embodiment of a conventional catheter.
可撓性合成樹脂で出来た管をカテーテル１としているが
、鉄管の管製造元に於てＸ線造影剤２を混入させである
ので、人体の液体管内に挿入して後Ｘ線を照射すれば該
カテーテル１が造影（図示せず）される。The catheter 1 is a tube made of flexible synthetic resin, but the iron tube manufacturer has mixed an X-ray contrast agent 2 into it, so if it is inserted into a liquid tube in the human body and then exposed to X-rays, The catheter 1 is imaged (not shown).
第２図は本考案の一実施例の先端部の側面断面図である
。FIG. 2 is a side sectional view of the tip of an embodiment of the present invention.
可撓性合成樹脂で出来た管をカテーテル３としてこの先
端部に磁気を滞びた物体４を接着結合又は内蔵させて磁
力線を有せしめている。A catheter 3 is a tube made of flexible synthetic resin, and a magnetized object 4 is adhesively bonded or built into the tip of the catheter 3 to provide lines of magnetic force.
人体の体液管内に挿入する前に、該カテーテル３が到着
する部位に近い体外に磁力線反応装置（図示せず）を設
けておいて該カテーテル３がその部位に到着すれば磁気
を滞びた物体４の磁力線が該磁力線反応装置（図示せず
）に反応する。Before being inserted into the body fluid duct of a human body, a magnetic field line reaction device (not shown) is installed outside the body near the site where the catheter 3 arrives, and when the catheter 3 arrives at that site, the object becomes magnetically stagnant. 4 magnetic field lines react to the magnetic field line reactor (not shown).
以上の様に、本考案の一実施例によれば、従来のカテー
テルではＸ線装置を必要としていたので、人体の液体管
内にカテーテルを正確に必要とする部位へ到着させるこ
とは使用上わずられしさを感じていたが、これら難点は
解消され、かつカテーテルの製造元に対し特別注文でＸ
線造影剤をカテーテル管材質に混入させる必要もなくカ
テーテルの製造コストを低減出来る等更に極めて容易に
カテーテルが必要とする部位に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 one embodiment of the present invention, since conventional catheters require an X-ray device, it is not necessary for the catheter to arrive at the required site accurately within the liquid canal of the human body. However, these difficulties have been resolved, and by special order to the catheter manufacturer,
It has features such as being able to reduce the manufacturing cost of the catheter without the need to mix a radiographic contrast agent into the catheter tube material, and being able to very easily know whether the catheter has arrived at the required site.
