ABSTRACT:
A single in-line filter hollow needle has an outer wall, a proximal end, a distal end with a pointed tip and a central opening between the ends for communicating fluids therethrough. The proximal end is secured to a luer lock for removable connection to a syringe. A filter is located in the central opening proximate to the tip. The outer wall of the needle has a frangible deformation proximate to the filter and remote from the end of the needle whereby the needle may be broken to expose a fresh point after fluid is aspirated through the needle to the syringe is filtered.
