Claim 11:
12. A female syringe system, comprising a female syringe formed of:
(i) a barrel member defining an internal cavity and having an internal, proximal-most edge that defines a proximal-most edge of the cavity, the barrel member having a proximal opening through which contents can be expelled from the internal cavity;
(ii) a plunger slidably positioned at least partially within the internal cavity, the plunger having a proximal-most tip, wherein the plunger slides within the internal cavity such that the proximal-most tip slides toward the proximal-most edge of the barrel member in a manner that expels contents of the barrel member through the proximal opening of the barrel member; and
(iii) a tapered female coupler on a proximal region of the barrel member, the female coupler having an opening that receives a complementary tapered male member of a male syringe to couple the female syringe with the male syringe, wherein the female coupler has a structural configuration that prevents the male member of the male syringe from protruding into the internal cavity of the barrel member when the male syringe is coupled to the female syringe, wherein the female coupler comprises a cylindrical body having an entirely smooth outer surface except for at least one lug thread positioned solely on a proximal-most edge of the female coupler.
