Needle cap for a medical syringe

A syringe comprising:

• a syringe barrel having proximal and distal ends and a syringe cavity therein;
• a plunger and coupled plunger stopper in the proximal end of the syringe barrel;
• a male Luer connector on the proximal end of the syringe barrel, in fluid communication with the syringe cavity;
• a Luer needle hub coupled to the male Luer connector, in fluid communication with the syringe cavity;
• a hollow syringe needle having a proximal end coupled to the Luer needle hub, in fluid communication with the syringe cavity, and a distal open needle tip;
• a needle cap having a tubular body with an inner wall surface defining a cap internal cavity therein, which captures the distal open needle tip, the inner wall surface further defining an open-ended, female Luer-taper profile, first cavity portion on a proximal end of the tubular body that is coupled to the needle hub, and the inner wall surface defining an open cap tip on a distal end of the tubular body;
• a needle seal within the cap internal cavity, dividing the cap internal cavity into a second proximal portion and a third distal portion, which are isolated from each other, the needle seal defining a through-bore in communication with both of the second proximal and the third distal portions, the through-bore having an internal diameter configured for mated sealing engagement with an outer diameter of the syringe needle captured therein;
• the distal open needle tip oriented in the third distal portion of the cap internal cavity in unobstructed, direct fluid communication with the open cap tip;
• and
• the tubular body having a tapered, frusto-conical outer surface profile on the distal end thereof, which terminates in the open cap tip.
