ABSTRACT:
A device for collection of a fluid sample, particularly a biological sample from an internal cavity of a mammal, comprises a barrel having an opening at one end thereof, a plunger operable axially within the barrel, the barrel and the plunger defining a fluid chamber having a volume which varies on axial movement of the plunger within the barrel, and a hollow, elongate tube extending from the fluid chamber through the opening in the barrel, the tube being in operative engagement with the plunger for axial movement to extend and retract the tube within respect to the barrel on axial movement of the plunger, and the tube being in fluid communication with the fluid chamber to provide a fluid flow path to and from the fluid chamber through the hollow tube. A method for collection of a fluid sample from an internal cavity of a mammal is also disclosed.
