Document name Abstract A subcutaneous implantable drug solution injector (1) comprises an injector body composed of a ring-shaped upper member (3) and a bottom member (2) for closing the bottom surface of the upper member (3), an injection tool body having an upper member A seal member (4) housed between the members (2) and closing an opening of the upper member (3) and forming a chemical liquid inflow space (10) in the injection tool main body And an exhaust port (5) communicating with each other. The sealing member (4) is capable of piercing a liquid medicine injection needle a plurality of times, and on the inner bottom face (21 a) of the injector main body facing the seal member (4), the antithrombogenicity and the suppression of microbial adhesion A coating (62) is provided. Furthermore, the coating (62) is a non-solidified film having a self-recovering property which can pierce the sealing member (4) and recover from damage by a chemical solution injection needle abutting the inner bottom surface (21 a) of the injection tool main body.【書類名】要約書 皮下埋め込み型薬液注入具(1)は、リング状の上部部材(3)と上部部材(3)の底面を閉塞する底部部材(2)とからなる注入具本体と、上部部材(3)と底部部材(2)間に収納され、上部部材(3)の開口を閉塞し、かつ、注入具本体内に薬液流入空間(10)を形成するシール部材(4)と、薬液流入空間(10)と連通する排出ポート(5)とを備える。シール部材(4)は、薬液注入用針の複数回の刺通が可能であり、かつ、シール部材()4と向かいあう注入具本体の内底面(21a)には、抗血栓性および微生物付着抑制被膜(62)が設けられている。さらに、被膜(62)は、シール部材(4)を刺通し、注入具本体の内底面(21a)に当接した薬液注入用針による損傷を回復可能な自己回復性を有する非固化被膜である。
