Abstract
Description
Q = A × ΔL/Δt
ここで、Qは流量、Aは感知部132の断面積、ΔLは流体レベルセンサ28によって測定された流体レベルの変化、またΔtは時間の変化である。吸引室26内の流体42のレベルの正確かつ精密な測定を行うことが重要である。流量測定の感度を高めるために、流体レベルセンサ28に対し直角の吸引室26の横断面積は、小さい必要がある。この機能は、吸引室26の感知部132によって達成される。流体42は、入口110を介して吸引室26の感知部132に入る。感知部132のより小さな断面積により、流体レベルセンサ28は、吸引室26内の流体レベルの変化を正確かつ精密に決定することができる。吸引室26の他の機能は、収集バッグポート32に流体的に結合された収集バッグ(図示せず)の交換中に、中断のない手術処置を補助するために追加の流体42を保持することである。収集バッグの交換中に当てはまるように、手術処置中に、流体を吸引室26内に貯蔵する必要が存在する場合、吸引室26の貯蔵部130は、流体貯蔵のために十分な体積を提供できる大きな断面を提供する。
