Abstract

A fluid aspiration device is provided having a syringe, a disposal reservoir and a disposal fluid passageway. The syringe has a variable-volume fluid chamber and an aspiration fluid passageway between the fluid chamber and a region of the body containing a fluid for aspiration. An aspiration valve is positioned in the aspiration fluid passageway. The disposal fluid passageway is between the fluid chamber and disposal reservoir and has a disposal valve positioned therein. The fluid is aspirated by expanding the variable volume of the fluid chamber to draw the fluid through the open aspiration valve into the fluid chamber. The aspiration valve is closed and the variable volume of the fluid chamber is contracted to open the disposal valve and displace the fluid into the disposal reservoir. When aspiration is terminated, the fluid aspiration device is maintained intact and the intact device including the fluid is disposed.
