Description
1.大量の流体を収集する場合、吸引キャニスタは、容積が比較的大きくなければならない。最も一般的には、容積が最大5リットルのキャニスタを使用する。大きいキャニスタは、吸引する物質を引き込むのに十分なだけ強力な負圧をキャニスタ内に生成する前に、大きい体積の空気をキャニスタから除去しなければならないので、負圧上昇率を遅くする。
2.吸引キャニスタ内の空気はポンプを通して引き込まれるので、使用後に吸引キャニスタを廃棄する場合でも、薄膜、弁、シリンダまたはピストンなどの使い捨てではないポンプ構成要素の汚染を防止することは、非常に困難である。汚染されたポンプは、これを通って流れる空気が雰囲気中に排出されるので、健康被害を生じる。
3.吸引器は、体液および嘔吐物を引き込むのに使用され、これは固体を含むことがある。吸引中に、空気もポンプに引き込まれる。真空ポンプは、一般的に空気または流体の給送に効率的であるが、大部分のポンプは、3タイプ全部の物質を給送するには非効率的である。
(a)3室キャニスタを含み、入口は第1室に通じ、第1室は固体を保持して、これが第1室から第2室へと通過するのを防止する手段を有し、第2室はその出口に逆止め弁を有し、弁は、液体および気体が通過して第2室から出ることを可能にし、第3室は空気を排出するための出口、および液体を排出するための追加出口を有し、第3室はさらに、その入口に逆止め弁を有し、これによって弁を通して物体が出るのを防止しながら、液体および気体が弁を通して入るのを可能にし、さらに、
(b)3室キャニスタに取り付けられ、これを周囲から密封する高度に軟質の薄膜を含み、軟質薄膜は、弁が設置された3室キャニスタを有する隔壁に取り付けられ、さらに、
(c)薄膜に取り付けられた駆動部材を含み、駆動部材の往復運動が薄膜の往復運動を誘発し、さらに、
(d)使い捨てポンプ・システムを駆動装置のハウジングに装着し、係合する手段を含み、手段は、同時にポンプ駆動部材を駆動装置に結合することができる。
(a)2室キャニスタを含み、第1室は入口と、第1室の出口にある逆止め弁とを有し、弁によって液体および気体が通過して第1室から出ることができ、第2室は、空気を排出するための出口と、液体を排出する追加的出口とを有し、第2室はさらに、逆止め弁を介して接続され、これによって液体または気体が弁を通って入ることができる一方、液体または気体が弁を通って出るのを防止し、さらに、
(b)2室キャニスタに取り付けられて、これを大気に対して密封する非常に軟質の薄膜を含み、軟質薄膜は、弁が設置された2室キャニスタを有する隔壁に取り付けられ、さらに、
(c)薄膜に取り付けられた駆動部材を含み、駆動部材の往復運動が薄膜の往復運動を誘発し、さらに、
(d)使い捨てポンプ・システムを駆動装置のハウジングに装着し、係合する手段を含み、手段は、同時に駆動部材を駆動装置に結合することができる。

- 前記結合手段が、前記往復運動要素と前記ポンプ部材のうち一方にあるロッドと、前記往復運動要素と前記ポンプ部材のうち他方にある受器とを含み、前記ロッドおよび前記受器が、締め付け具によって相互にロックするようになっていて、それにより前記係合を提供する、請求項2に記載の装置。
- 前記ロッドが、前記ポンプ・ユニットの前記駆動ユニットへの前記取り付け中に、前記受器に入る、請求項3に記載の装置。
- 請求項1の装置とともに使用する取り付けおよび取り外し可能なポンプ・ユニットで、さらに、
下端に流体入口を有する第1区画を含み、前記流体入口が、第1逆止め弁を介して前記ポンプ室と連絡し、これにより流体が前記ポンプ室に流入することだけができ、さらに、
流体出口を有する第2区画を含み、前記第2区画が、第2逆止め弁を介して下端にて前記ポンプ室と連絡し、これにより流体が前記ポンプ室から流出することだけができるポンプ・ユニット。 - 前記可撓性の薄膜は、前記ポンプ室が収縮状態になると、前記ポンプ室に保持される前記最小容積を超える量の流体または固体を収容するため、前記周囲と前記中心の間で降伏し、外側に膨脹するよう伸張可能であり、それによって前記駆動ユニットが、前記近位位置を通して前記中心を往復運動させることができる、請求項1に記載のポンプ・ユニット。
- 前記ポンプ・ユニットは、前記ポンプ入口に接続されて前記ポンプ・ユニットにより給送される物質を収容する廃棄物収集容器を備える、請求項1に記載のポンプ・ユニット。
