ABSTRACT:
One end of a hollow cylindrical tube is attached to a tubing positionable in a patient's body. A radial flange on the tube supports a collar in abutting relationship to one flange surface. Lugs extend integrally from the collar through the flange for disposition against the opposite flange surface. The collar extends radially past the tube's inner periphery and has slots at its inner periphery. Stops integral with the inner periphery of the collar are annularly displaced relative to the slots. Ramps on the collar lead to the stops. A piston in the tube along part of its length has, at the end within the tube, a sleeve in sealed relationship with the tube is inner periphery. Splines have grooves at spaced positions along their axial lengths at the radially outer ends of the splines. A handle at the piston axial end has an aperture to receive a user's finger for manual adjustment of the piston axially relative to the tube. In use, the piston is withdrawn axially within the tube to create a vacuum for sucking fluid or tissue from the patient's body into the tube. This piston withdrawal continues until one set of the spline grooves becomes aligned with the collar slots. The piston is then rotated to dispose the splines against the stops. In this position, the piston cannot be rotated or moved axially because of the non-alignment between the spline grooves and the collar slots. This causes the fluid to be retained within the tube.
