ABSTRACT:
A small volume effusion trap for use with common surgical or medical instruments having a housing unit with two elongate, rigid, hollow members, a vacuum source, and a drainage tube. In an embodiment, a standard, commercially available sample vial attaches to the housing unit to collect the effusion. The sample vial can be utilized directly in standardized diagnostic and/or therapeutic analysis apparatuses. To collect a small volume of effusion, one elongate, rigid, hollow member is connected to standard surgical or medical aspirators and the other elongate, rigid, hollow member is connected to the vacuum line. With suction applied to the elongate, rigid, hollow member, an area of reduced pressure is produced in the sample vial so as to cause aspirated effusion to proceed from the surgical or medical apparatus through the elongate, rigid hollow member into the sample vial.
