Abstract

Fine needle arrangement for taking a sample of cells from suspicious lesions by using fine needle aspiration (FNA) technique, including a tubular needle member (1), a storage compartment (2) enclosing a chamber, and a coupling (3) to which a connector may be attached. The chamber is configured with a gradually increasing cross-sectional area from the distal part of the chamber to the proximal part of the chamber, such that the chamber has no residual spaces where cell samples may be trapped, and that an efficient air streaming is achieved.
