Abstract
Syringes for providing fluid communications are provided. The syringes include a connector body section having a tip portion and a gravity-assisted valve, and a barrel section. One or more syringes include a configuration of the gravity-assisted valve to allow bidirectional fluid communications between the tip portion and a fluid reservoir when the syringe is pointed downward. One or more syringes include a configuration of the gravity-assisted valve to prohibit fluid communication from the fluid reservoir to the tip portion when the syringe is pointed upward. One or more syringes include a gas pathway extending from an interstitial space of the connector body section to an interior volume of the plunger defining a gas reservoir.
