Abstract
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.
