    摘要： An apparatus for separating gas bubbles that may be entrained in perfusate flow prevents such bubbles from continuing downstream and entering an organ or tissue. The apparatus may include a chamber having a top wall, a bottom wall and side walls. The chamber may include an inlet configured to allow at least one of gas and liquid to enter the chamber, an air opening configured to allow at least gas to exit the chamber and a first liquid opening configured to allow at least liquid to exit the chamber. The apparatus may function as an accumulator that reduces or eliminates pulsatility of the liquid flow and pressure. The apparatus may include a minimum volume of gas, initially or through the accumulation of gas, such that flow and pressure fluctuations in the liquid are dampened or eliminated. The apparatus may include a sampling port in a wall of the chamber.

    摘要： A cleaning machine for cleaning a surface in which cleaning solution is dispensed to the surface and substantially extracted along with the dirt on the surface in a continuous operation is provided. The cleaning machine includes an airflow source that produces an airflow directed out of an outlet. A duct cover covers the outlet. The duct cover includes at least one opening that is sized and oriented to distribute the air evenly across the outlet.

    摘要： An extractor-type surface cleaning machine includes a base or foot having a suction nozzle and a handle that is pivotally coupled to the foot and moveable between upright and inclined positions. The recovery tank is removably securable to the foot and fluidly communicates with the suction nozzle and the accessory. The recovery tank defines a collection chamber and a passage having an inlet in communication with the suction nozzle and an outlet. A valve member is moveable between a closed position substantially covering the outlet and an open position. Movement of the handle to the upright position moves the valve member to the closed position to block the passage during cleaning with the accessory hose. Movement of the handle to the inclined position allows movement of the valve member to the open position so that suction from the collection chamber is communicated to the suction nozzle for floor cleaning.
