A medical device comprising: a syringe barrel including a sidewall having an interior surface defining a chamber for retaining a liquid, an open proximal end and a distal end including a distal wall with a tip extending distally therefrom having an open passageway in fluid communication with said chamber , the sidewall having a first sidewall portion and a second sidewall portion ; a plunger rod comprising a proximal end , a distal end and a body extending from the proximal end to the distal end , the plunger rod disposed within the chamber and moveable in the proximal and distal direction within the chamber ; a stopper disposed within the chamber and moveable in the proximal and distal direction within the chamber , the stopper having a stopper including a distal face , a proximal end ; and, the distal end of the barrel includes the first sidewall portion to form a releasable fluid-tight seal between the stopper and the interior surface of the first sidewall portion of the barrel , characterized in that : the open proximal end of the barrel includes the second sidewall portion including a plurality of air venting grooves embedded within the interior surface of the second sidewall portion of the barrel to break the releasable fluid-tight seal between the stopper and the sidewall of the barrel ; and a porous membrane disposed over the plurality of air venting grooves to permit air to flow out of the chamber and to prevent liquid from exiting the chamber , wherein the porous membrane disposed over the plurality of air venting grooves extends in a direction substantially parallel to a longitudinal axis of the chamber . a syringe barrel including a sidewall having an interior surface defining a chamber for retaining a liquid, an open proximal end and a distal end including a distal wall with a tip extending distally therefrom having an open passageway in fluid communication with said chamber , the sidewall having a first sidewall portion and a second sidewall portion ; a plunger rod comprising a proximal end , a distal end and a body extending from the proximal end to the distal end , the plunger rod disposed within the chamber and moveable in the proximal and distal direction within the chamber ; a stopper disposed within the chamber and moveable in the proximal and distal direction within the chamber , the stopper having a stopper including a distal face , a proximal end ; and, the distal end of the barrel includes the first sidewall portion to form a releasable fluid-tight seal between the stopper and the interior surface of the first sidewall portion of the barrel , characterized in that : the open proximal end of the barrel includes the second sidewall portion including a plurality of air venting grooves embedded within the interior surface of the second sidewall portion of the barrel to break the releasable fluid-tight seal between the stopper and the sidewall of the barrel ; and a porous membrane disposed over the plurality of air venting grooves to permit air to flow out of the chamber and to prevent liquid from exiting the chamber , wherein the porous membrane disposed over the plurality of air venting grooves extends in a direction substantially parallel to a longitudinal axis of the chamber . the open proximal end of the barrel includes the second sidewall portion including a plurality of air venting grooves embedded within the interior surface of the second sidewall portion of the barrel to break the releasable fluid-tight seal between the stopper and the sidewall of the barrel ; and a porous membrane disposed over the plurality of air venting grooves to permit air to flow out of the chamber and to prevent liquid from exiting the chamber , wherein the porous membrane disposed over the plurality of air venting grooves extends in a direction substantially parallel to a longitudinal axis of the chamber . <EOS>
