【発明の詳細な説明】
（１）（産業の利用分野）
本発明は、進行癌患者の化学療法における抗癌剤動脈内
注入に用いる皮下埋め込み式リザーバーに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (1) (Field of Industrial Application) The present invention relates to a subcutaneously implantable reservoir used for intra-arterial injection of anti-cancer agents in chemotherapy for patients with advanced cancer.
（２）（従来の技術）
癌の治療の目的で、進行癌患者の動脈内に抗癌剤を注入
するための手段として、カテーテルを動脈内に挿入し留
置する方法による場合、従来は抗癌剤注入口として該カ
テーテルの末端を体外に露出させていたので、その露出
部の清潔維持を必須なものとしていた。(2) (Prior Art) For the purpose of cancer treatment, when a catheter is inserted into the artery and left in place as a means for injecting an anticancer drug into the artery of a patient with advanced cancer, conventionally, an anticancer drug injection port has been used. Since the end of the catheter is exposed outside the body, it is essential to maintain the cleanliness of the exposed part.
このため、例えば、患者の入浴時にその露出部の清潔を
保つことが極めて困難であるなどの問題を生じ、患者の
日常生活に大きな障害となっている。また、治療上も薬
剤注入に際し、無菌的に操作するため煩雑な手順を要す
ることや露出部からの感染、さらにはその破損による出
血の可能性などが、このカテーテル留置法自体を煩わし
いものとしている。This causes problems such as, for example, it is extremely difficult to keep the exposed area clean when the patient takes a bath, which is a major hindrance to the patient's daily life. In addition, this method of catheter placement itself is cumbersome from a medical standpoint, as it requires complicated procedures to operate aseptically, and there is a possibility of infection from the exposed site, as well as bleeding due to damage. .
これらのことが、進行癌患者の残された期間における社
会復帰、あるいは外来での治療を行う上での大きな妨げ
となっていた。These problems have been a major hindrance to patients with advanced cancer returning to society during their remaining years or receiving outpatient treatment.

決手段として、患者の皮膚下に埋め込み、抗癌剤の注入
を容易にし、患者の日常生活を制約することなく、かつ
生体適合性の良い装置を提供するものである。(3) (Technical means) In order to solve the above problem, it is possible to inject the anticancer drug percutaneously without exposing the end of the catheter placed in the artery to the outside of the body, but this injection is easy. Furthermore, since anticancer drugs, by their nature, attack human tissue, leakage of the drug outside the catheter must be avoided at all costs. . As a solution to this problem, the present invention provides a device that is implanted under the patient's skin, facilitates injection of anticancer drugs, does not restrict the patient's daily life, and has good biocompatibility.

テーテル８を嵌入し、固着させてなるものである。(4) (Example) An example of the present invention will be explained with reference to the drawings. Figure 1 is a sectional view taken along line A-A' in Figure 2 (plan view of the reservoir). The sheet 2 is fitted onto the upper part of the reservoir main body 3, and the lid 1 is fixed by adhesive.Then, the sheet 5 is fitted onto the lower part of the reservoir main body 3 to form the storage part 4, and the bottom [6] is formed. A catheter 8 having a valve 9 is inserted into a hole 7 provided in one wall of the reservoir body 3 and fixed by adhesive.

、また、弁９は、カテーテル８より貯留部４へ薬剤等が
逆流することを防ぐ一方弁としなければならない。The lid 1, the sheet 2, the reservoir body 3, the bottom plate 6, and the catheter 8 are preferably made of silicone rubber in order to be suitable for use in living organisms, but the sheet 5 is made of a material that cannot be easily penetrated by the needle used for injecting anticancer drugs. Unfortunately, the valve 9 must be a one-way valve that prevents the medicine, etc. from flowing back from the catheter 8 to the reservoir 4.

手術を行う。(5) (Operation) A catheter to be placed in an artery is inserted via, for example, the left thoracic artery, deep femoral artery, brachial artery, subclavian artery, etc., and the end of the catheter is inserted into the blood vessel as shown in the reference figure. A surgery is performed in which the catheter 9 fitted into the reservoir body 4 is inserted and ligated outside, and the reservoir is implanted under the patient's skin.

入時の針穴による薬剤の漏れを完全に回避できる。The drug is injected by puncturing the reservoir 4 with a needle as shown in the figure, but even if this is repeated, the reservoir 4
The medicine inside the reservoir is first blocked by the wall of the main body 3,
Next, it is blocked by the sheet 2 and the lid 1, and leakage of the drug through the needle hole during injection can be completely avoided.
なお、抗癌剤の注入を終えたときは、更に抗血液凝固剤
の注入を行うべきである。Furthermore, when the injection of the anticancer drug is finished, an anticoagulant should be further injected.
（６）（本発明の効果） この発明は、次のような特別の効果を有する。(6) (Effects of the present invention) This invention has the following special effects.
（ア）抗癌剤の注入にあたり、穿刺部位を除き無菌的防
