Abstract

A filtering needle assembly for use in administering a liquid payload, including: a needle and connector portion; a filtering needle body cap; a seal plug, and a filter: The seal plug initially lacking a needle channel so that a distal end of a hollow needle must be forced through the distal end of the seal plug while the seal plug is retained by a holding tool with a hollow midline of adequate depth to receive the protruding end of the hollow needle. An attempt to reuse the filtering needle assembly with a second insertion of a hollow needle into the filtering needle assembly will not work as the distal end of the hollow needle will push the seal plug distally rather than traverse the seal plug.
