Syringe with gravity-assisted valve

A syringe comprising:

• a connector body section defining a longitudinal axis and comprising,
• a tip portion for fluid ingress and egress;
• and
• a gravity-assisted valve comprising a valve body defining an elongated valve cavity generally aligned with the longitudinal axis, a first port operatively coupled to the tip portion, a second port, and a valve member movable between a sealable end of the elongated valve cavity proximal to the first port and a non-sealable end of the elongated valve cavity proximal to the second port;
• and
• a barrel section generally aligned with the longitudinal axis and slidably engaged with a plunger, the barrel section defining a fluid reservoir within a volume of the barrel section controllable by an end of the plunger proximal the connector body section, the fluid reservoir operatively coupled to the second port of the gravity-assisted valve,
• wherein the gravity-assisted valve is configured to prohibit fluid communication from the fluid reservoir to the tip portion when the syringe is oriented with the tip portion pointing in a generally upward direction.
