Abstract
【解決手段】真空室と、周囲圧力室と、チャージストローク中は真空室から周囲圧力室への一方向の流れとなるように構成されたバルブと、ポンプに液体を保持するように構成された液体フィルターとを含むシステムが、説明的に示されている。液体フィルターは、チャージストローク中に真空室に液体を保持するように構成されている。液体フィルターは、動作ストローク中、周囲圧力室に液体を保持するように構成され得る。ピストンは、真空室と周囲圧力室との間に配置され得、通路が、真空室と周囲圧力室とを流体的に結合してもよく、およびバルブが、通路を通る流体の流れを制御するように構成され得る。さらに、ルーメンが真空室をドレッシングに結合して、ドレッシングに陰圧を送達し得る。
