Abstract
【解決手段】注入ポンプに取り付ける形態とされた供給装置用アダプタ100は、注入装置の流入チューブと注入装置の中央ポンプ係合チューブとに取り付ける形態とされた第一のコネクタ108と、前記第一のコネクタと連通状態に配置された自由流れ防止機構300と、内部の気泡を光学的に検知し得る形態とされたサンプルセル124とを備えている。
【選択図】 図2B
Description
上記のことに加えて、米国特許第5,704,584号にて論じられた自由流れ防止技術には難点がある。閉塞機構は良好に機能するが、注入装置を通る流れを選択的に停止させるために別個の機構を形成することは比較的コスト高である。図1Bに図示されたような別個の挟みクリップは、注入装置のコストを15乃至20%増大させる可能性がある。1つの装置当たりのコストはかなり僅かではあるが、注入装置を毎日交換することから、累積してかなりのコストとなる。極めて競争の激しい医療分野において、1つの装置当たり数セントであっても、販売数量に劇的な影響を与える可能性がある。(特許文献2参照)
このように、圧力の監視、空気の検知及び流れの閉塞を改良することを可能にする機構が必要とされている。かかる機構は、比較的経済的で且つポンプ及び注入装置を使用する際の間違いの発生を減少させるものでなければならない。更に、かかる機構は、多岐に亙る材料で出来た注入装置を使用することを可能にするものでなければならない。
本発明の別の目的は、光センサ装置により粘度及び閉塞の監視を容易にする、上記の如き機構を提供することである。
本発明の別の目的は、注入装置を通る流体の流れがポンプによって駆動されない限り、注入装置を通る自由流れを防止する機構を提供することである。
注入装置の上流部分、下流部分及びポンプ係合部分に取り付け得る形態とされた供給装置のアダプタの特定の図示した実施の形態にて本発明の上記及びその他の目的が実現される。
次に、本発明の色々な要素を所定の参照番号で表示し、また、当業者が本発明を実施し且つ使用することを可能にし得るように本発明に関して説明する図面について以下に説明する。以下の説明は、本発明の原理の単に一例にしか過ぎず、特許請求の範囲を限定するものと見なすべきではないことを理解すべきである。
