076 and Japanese Patent Application No. 1-171569. In these techniques, the reservoir and the catheter are integrally molded and fixed to each other, so that the reservoir and the catheter are always integrated. Therefore, since one size of catheter corresponds to the reservoir, it cannot be replaced with a catheter of a different size.

The drawing is a side cross-sectional view of a conventional embodiment. A conventional body-embedded reservoir is configured by providing a rubber button 7 on a body portion 6 , a drug solution reserve storage portion 8 and a catheter 9 fixed as shown in the figure. In the case of use, the body-implanted reservoir 6 is buried under the skin of a patient (not shown), and the tip of the catheter 9 is inserted into the affected area of the body fluid tube, defect, organ, etc. of the patient, and the syringe needle is externally applied. The rubber button 7 is punctured (not shown) to inject a therapeutic drug into the reservoir 8 to reserve the drug, and the drug flows out to the affected area via the catheter 9. FIG. 2 is a side sectional view of an embodiment of the present invention. The body-embedded reservoir 1 is a partial drug solution storage unit 11 that reserves a drug solution.
It is composed of a main body 1 and a catheter fixing device 2.
The basic usage is no different from that of the previous embodiment. The catheter fixing device 2 includes a fixing pipe 24 with a net provided with a metal pipe 22 having an outer diameter suitable for a catheter 21 of an arbitrary size, a fixing tip 23, and a reamer surface portion 24 '.
And a packing 25 with a chemical liquid backflow prevention valve.
At the time of assembling, the packing 25 with the chemical liquid check valve is inserted into the back of the catheter fixing device portion 2 of the main body 1, and the fixing tip 23 in which the catheter 21 of an arbitrary size is inserted and fitted into the metal pipe 22 is inserted. The in-body implantable reservoir is completed by screwing and fixing with the attached fixing adapter 24.
Reference numeral 24 'is a surface subjected to reamer processing. In the clinical practice, when exchanging a catheter of an arbitrary size, a fixed tip 23 with a metal pipe 22 suitable for the arbitrary size and a preparatory group including the arbitrary catheter are set to exchange catheters of various sizes. It is easily possible.
前記した様に、リザーバー本体１に対して、任意サイズ
の金属製パイプ２２に接合したカテーテル２３を選択し
てカテーテル固定装置部分２へ組立が可能であるので、
一つのリザーバーに対して、数種類のカテーテルを接続
する事が出来る効果を有して、既に体内に埋め込んだリ
ザーバー本体は其の儘に置いて、カテーテルのみをサイ
ズ変更したカテーテル固定装置の交換が可能で便利であ
る。As described above, since it is possible to select the catheter 23 joined to the metal pipe 22 of an arbitrary size with respect to the reservoir body 1 and assemble the catheter fixing device portion 2,
It has the effect that several types of catheters can be connected to one reservoir, and the reservoir body already embedded in the body can be placed in the same place and the catheter fixing device with only the catheter resized can be replaced. It is convenient.
