A syringe purging device comprises a closed chamber into which air and/or any excessive amount of a hazardous liquid, such as a chemotherapy drug, is ejected from a syringe to overcome the health hazard created by openly purging syringes into the air or into a pad of gauze material. A sharp open end of a hollow needle of a syringe is sealingly inserted into the chamber and the syringe is activated to purge any air and/or excess liquid into the chamber which expands as necessary. Preferably, the chamber is then further expanded to reduce the pressure therewithin to better ensure clean withdrawal of the needle from the chamber or extension of the needle beyond the chamber and retention within the chamber of any fluids ejected from the syringe.

Method and apparatus for catching fluids purged from a syringe

A syringe purging device comprises a liquid-tight chamber into which air and/or any excessive amount of a hazardous liquid, such as a chemotherapy drug, is ejected from a syringe to overcome the health hazard created by openly purging syringes into the air or into a pad of gauze material. A sharp open end of a hollow needle of a syringe is sealingly inserted into the liquidtight chamber, and the syringe is activated to purge any air and/or excess liquid into the chamber. The liquidtight chamber may be closed, with any liquid ejected thereinto being retained by absorption into a wad of absorbent material contained within the chamber. Alternately, the chamber may be vented to the atmosphere through a hydrophobic filter such that air injected into the chamber passes through the filter, but any liquid is retained within the chamber since it cannot pass through the hydrophobic filter. After the syringe is purged of any air and/or excess liquid, its needle is then withdrawn from the chamber or extended beyond the chamber such that the syringe may be used for an injection.
