Syringe assembly

An operable syringe assembly comprising:

• an elongate substantially cylindrical barrel having a chamber for retaining fluid;
• a tapered tip extending from a distal end of said barrel having a passageway therethrough communicating with said chamber;
• a flange portion projecting radially outwardly from a proximal end of said barrel, said proximal end having an aperture therethrough;
• a stopper slidably positioned in fluid-tight engagement inside said barrel, said stopper capable of moving fluid from said chamber through said passageway upon its movement toward said distal end, said stopper capable of facilitating the drawing of fluid into said chamber through said passageway upon its movement away from said distal end;
• a plunger rod having an elongate body portion engaging said stopper to facilitate operation of said stopper, said body portion extending outwardly from said proximal end of said barrel, through said aperture;
• a flexible cover having a closed first end and an open second end, said open second end being attached to said barrel covering said aperture and containing that portion of said elongate body portion of said plunger rod protruding from said aperture, said cover being flexible enough and strong enough to allow movement of said plunger rod for operating said syringe without tearing, said cover acting as a barrier for helping to block the transfer of fluid and particulate matter between said chamber and the environment.
