Claims (10)
- 患者よりも高い位置に配置された容器から、患者に対して溶液の静脈投与を行うための自動準備IV溶液投与システムであって、
注入口と排出口を備え、前記容器に結合するように構成された前記注入口から、前記排出口へと前記溶液を流動させる結合機構と、
天井壁、底壁、側壁、注入口および排出口を備え、前記注入口にて前記結合機構の排出口と結合し、溶液の流動によって形成された溶液滴を受容して前記底壁および側壁によって定められるリザーバを形成するとともに、前記リザーバの形成に伴って置換される内部の空気を排出させる開口部と該開口部を覆う排気栓と該排気栓が溶液の飛沫に接触するのを防ぐためのはねよけを、前記側壁の前記天井壁よりも低く且つ前記底壁よりも高い位置に備えた、点滴チャンバーと、
前記点滴チャンバーの排出口に結合され、前記リザーバからの流れを受容するための患者の静脈針に取り付けられる終端部と、前記リザーバが少なくとも前記排気栓と同じレベルに達するまで該患者導管の内部の空気を前記終端部から排出させることにより内部の空気および液体の流動を抑制する流動抑制手段と、を備える当該患者導管と、
を具備し、
前記排気栓が前記リザーバによって濡れたときには前記排気栓を介して前記点滴チャンバー内へ空気が侵入出来ないとともに、溶液は前記点滴チャンバーから排出できなくなることを特徴とする自動準備IV溶液投与システム。 - 前記流動抑制手段は穴が配備された終端キャップを有し、該終端キャップは前記終端部に取り付け可能であることを特徴とする請求項1に記載の自動準備IV溶液投与システム。
- 前記終端キャップは、前記患者導管内に存在する空気が前記終端キャップの穴を通り抜けることを許容するとともに前記終端キャップからの薬剤の漏れを抑制するような、終端排気栓より構成されていることを特徴とする請求項2に記載の自動準備IV溶液投与システム。
- 前記終端排気栓は親水性の多孔性材料によって構成されていることを特徴とする請求項3に記載の自動準備IV溶液投与システム。
- 前記流動抑制手段は、前記患者導管上に、前記点滴チャンバーから患者を分離するために前記患者導管を選択的に閉塞することが可能な流路閉塞手段を更に有していることを特徴とする請求項2に記載の自動準備IV溶液投与システム。
- 前記結合機構の排出口と前記点滴チャンバーの注入口との間を連結し、前記点滴チャンバーと前記結合機構との相対距離を引き離すことにより、前記点滴チャンバーを観察しやすく、且つ前記連結機構による妨害を最低限にした状態で前記点滴チャンバーを操作できるように、前記点滴チャンバーを患者に接近した位置に配置出来るような長さを有する、柔軟性を有する導管を、更に具備することを特徴とする請求項1に記載の自動準備IV溶液投与システム。
- 溶液滴を形成するための点滴口が前記点滴チャンバーの天井壁に配備されていることを特徴とする請求項1に記載の自動準備IV溶液投与システム。
- 前記側壁開口部の高さは、リザーバが前記点滴チャンバーによって定められる総容積の約1/3を占領するレベルに一致することを特徴とする請求項1に記載の自動準備IV溶液投与システム。
- 前記排気栓は、吸収体と、前記側壁開口部に結合するとともに前記吸収体の形状を受容するため空洞を規定する筺体を有し、前記吸収体はリザーバによって濡れることに反応して膨張する超吸収体ポリマーで構成されていることを特徴とする請求項1に記載の自動準備IV溶液投与システム。
- 前記排気栓は、更に、抗菌剤を含んでいることを特徴とする請求項9に記載の自動準備IV溶液投与システム。
