Abstract:
1. An aspirating system, comprising: a surgical device including an aspirating output port; an aspirating unit including a vacuum port; a primary cassette having a vacuum input port for connection to the vacuum port of said aspirating unit, and a vacuum output port; a disposable secondary cassette including: a housing having first and second opposing open ends between which a hollow cavity or interior volume is provided; first and second caps secured to said first and second ends, respectively, for providing an air tight seal therewith; partition means installed within said housing for dividing the volume into first and second regions having an air tight and fluid seal therebetween, said first and second regions being located between interior sides of said first and second caps, respectively; first and second ports mounted onto and through said first and second caps, respectively, for providing a fluid pathway into or out of said first and second regions, respectively, said first region being filled with a fluid or liquid, and said second region with ambient air; said first port being connected to said vacuum output port of said primary cassette, and said second port being connected to said aspirating output port of said surgical device, whereby as said primary cassette vacuum port source sucks fluid out of said first region, said partition means responds by decreasing the volume of said first region, and increasing the volume of said second region, thereby 25 producing a vacuum at said second port for sucking fluid from said surgical device into said second region of said housing.
