Description
一態様においては、本発明は、医療器具の取り扱い方法を特徴とする。本発明の方法は、液体抗菌薬を医療器具内に注入することを含む。
本発明の一態様は、医療システムであって、前記医療システムはシリンジシステムを具備し、該シリンジシステムは、第1区画及び第2区画を有するハウジングであって、前記第1区画及び第2区画が互いに連通可能に構成される、ハウジングと、前記第1区画に収容される第1組成物と、前記第2区画に収容される第2組成物とを備え、前記第1の組成物及び第2の組成物が第1区画と第2区画の間に配置されるセパレータによって互いから隔離され、前記セパレータは、第1区画と第2区画の間を水密的にシールし、かつ、圧力を受けると所定の領域において優先的に破壊されて、第1組成物と第2組成物とを組み合わせるように構成される、医療システムを提供する。
図1A〜図1Cには、医療器具10の取り扱い(例えば消毒)方法12が示される。図示されるように、医療器具10は、一部45が身体の皮膚80下に配置される透析カテーテル15である。カテーテル15は、液体抗菌薬20をシリンジシステム200からカテーテルに搬送することにより処理される(図1B及び図1C)。抗菌薬20は、微生物が活動する可能性を低減するために、カテーテル15の内部を消毒することができる。場合によっては、抗菌薬20をカテーテル15の外面に拡散させ、さらに微生物の活動及び/又は体内における感染症を低減させてもよい。液体抗菌薬を用いるため、抗菌薬20は、どちらかというと処理を行うことが少なく、器具10まで好適に搬送することができる。処理が減ることで、汚染及び/又は感染が起きる可能性も低減することになる。
例えば、ハウジング210は、通気弁295を備えていてもよい。図2Aにおいて仮想線にて示されるように、通気弁295を基端側区画220に対して連結し、シリンジシステム200において圧力制御が行えるようにしてもよい。
また、他の好適なシリンジシステムは、例えば米国特許第5,971,953号明細書、同第5,817,056号明細書、同第5,685,846号明細書、及び同第4,613,326号明細書に開示されている。なお、これら米国特許明細書は、その全内容が本明細書において開示されたものとする。
