The syringe also includes a barrel having a barrel tube having proximal and distal ends and an interior configured to accept a portion of the plunger, a tip fixedly coupled to the proximal end of the barrel tube, a post fixedly attached to the tip and extending within the barrel tube toward the distal end, the tip configured to partially extend into the center passage of the plunger, and a gas passage extending from a proximal end of the tip to the distal end of the post. ## Claims ### Claim 1 A vial adapter comprising: a proximal end portion having a needle configured to couple with a vial; a distal end portion comprising a cavity extending into the vial adapter and configured to receive a portion of a syringe therein, the cavity comprising a recess extending around an inner surface of the cavity; a gas passage extending between the recess of the cavity and the needle, and configured to fluidly couple with a gas passage of a syringe coupled to the cavity; and a liquid passage, extending between the recess of the cavity and the needle, configured to fluidly couple with a liquid passage of the syringe coupled to the cavity. ### Claim 2 (depends on 1) The vial adapter of claim 1, wherein the cavity defines a female luer fitting and is configured to receive a portion of a syringe defining a male Luer fitting. ### Claim 3 (depends on 1) The vial adapter of claim 1, wherein the liquid passage extends to a distal end portion of the needle. ### Claim 4 (depends on 1) The vial adapter of claim 1, wherein the gas passage extends between the needle and a proximal end portion of the cavity. ### Claim 5 (depends on 1) The vial adapter of claim 1, wherein the gas passage extends through a tip portion of the needle. ### Claim 6 (depends on 1) The vial adapter of claim 1, wherein the liquid passage extends through an exterior side surface of the needle. ### Claim 7 (depends on 1) The vial adapter of claim 1, wherein the gas passage and the liquid passage are spaced apart. ### Claim 8 (depends on 1) The vial adapter of claim 1, wherein the recess extends around the inner surface of a distal end portion of the cavity, and the gas passage extends between a proximal end portion of the cavity and the needle. ### Claim 9 (depends on 1) The vial adapter of claim 1, wherein the syringe can be coupled to the cavity in any rotational position, relative to the vial adapter, while maintaining fluid coupling of the recess and the liquid passage. ### Claim 10 (depends on 1) The vial adapter of claim 1, further comprising a capture feature configured to engage against a lid of vial when the vial adapter is coupled with a vial. ### Claim 11 (depends on 1) The vial adapter of claim 1, wherein, when the needle of the vial adapter is coupled with a vial, and a syringe is coupled with the cavity of the vial adapter, the gas passage is fluidly coupled between an interior of the vial and the gas passage of the syringe, and liquid passage is fluidly coupled between an interior of the vial and the liquid passage of the syringe. ### Claim 12 (depends on 11) The vial adapter of claim 11, wherein a liquid can move from the vial into the syringe through the liquid passage, and a gas can move from the syringe into the vial through the gas passage. ### Claim 13 A vial access system comprising: a syringe comprising: a barrel tube and a plunger tube; the barrel tube comprising a proximal end portion, a distal end portion, a first liquid passage; and a first gas passage, wherein a first fluid volume is formed between the barrel tube and the plunger tube, and the plunger tube comprises a second fluid volume, and wherein the first liquid passage extends through the proximal end portion of the barrel tube to the first fluid volume, and the first gas passage extends through the proximal end portion of the barrel tube to the second fluid volume; and a vial adapter comprising: a proximal end portion having a needle configured to couple with a vial; a cavity extending into the vial adapter and configured to receive a portion of the syringe therein, the cavity comprising a recess extending around an inner surface of the cavity; a second gas passage extending between the recess of the cavity and the needle; and a second liquid passage extending between the recess of the cavity and the needle, wherein, when the syringe is coupled to the vial adapter, the second gas passage is fluidly coupled with the first gas passage of the syringe, and the second liquid passage is fluidly coupled with the first liquid passage of the syringe. ### Claim 14 (depends on 13) The vial access system of claim 13, wherein, when the syringe is coupled to the vial adapter, the proximal end portion of the barrel tube is positioned within the cavity. ### Claim 15 (depends on 13) The vial access system of claim 13, wherein, when the syringe is coupled to the vial adapter, the syringe and the vial adapter are rotatable relative to each other while maintaining the fluid coupling between the first liquid passage and the second liquid passage. ### Claim 16 (depends on 13) The vial access system of claim 13, wherein, when the syringe is coupled to the vial adapter, the syringe and the vial adapter are rotatable relative to each other while maintaining the fluid coupling between the first gas passage and the second gas passage.
