Claim 17:
18. 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 female coupler on a proximal region of the barrel member, wherein the female coupler couples to a male member of a male syringe, wherein the male syringe includes a concentric sleeve that surrounds the male member, and wherein the male member is longer in length than the sleeve such that a tip of the male member extends past a tip of the sleeve, and wherein the male member and female coupler have complementary tapers that limit a depth of insertion of the male member into the female coupler, 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.
