An impact releasable pole mounted syringe is described which includes a pole member having a gripping end and a syringe attachment end. The syringe attachment end has a receptacle with an opening adapted to telescopically receive a syringe. The pole member has a flexible finger protruding past the syringe attachment end and biased radially away from the pole member. The finger has an engagement member positioned at a remote end. A syringe is provided having a plunger end and a needle end. The plunger end is adapted for telescopic insertion into the receptacle at the syringe attachment end of the pole member. The syringe has an annular collar serving as a stop to limit the telescopic insertion of the syringe into the receptacle. The syringe has an engagement channel adapted to receive the engagement member. A pressure sensitive stop is provided to maintain the syringe and the pole member in the engaged position wherein the engagement member is engaged with the engagement channel to couple the syringe with the pole member. Upon an axial pressure being placed upon the needle end of the syringe the pressure sensitive stop permits the syringe to travel further into the receptacle of the pole member, moving the engagement member along the engagement channel until it is released. Upon the engagement member being released from the engagement channel the biased finger springs radially away from the pole member permitting unrestricted withdrawal of the syringe from the receptacle.
