Abstract: An exemplary syringe adapter for coupling with a syringe may include a housing. A needle-free connector may be disposed in the housing. A communication member may be in slidable engagement with the housing. The communication member may be slidable, with respect to the housing, between an unactuated state and an actuated state of the syringe adapter. A cannula may extend from the communication. In the unactuated state, the cannula may be retracted within the needle-free connector. In the actuated state, the cannula may protrude through and axially beyond the needle-free connector.

Abstract: Check valve are disclosed having a primary seal and a secondary seal, where the primary and secondary seals resist movement of a fluid through the check valve, and the secondary seal can provide a backup seal in an instance where the check valve does not function as intended. The primary and secondary seals can be formed by first and second sealing ridges, respectively, and a valve body can be positioned within the check valve, between a valve support, the first sealing ridge, and a second sealing ridge. The valve body is configured to move relative to the first and second sealing ridges, and can have a position wherein a portion of the valve body is engaged against any of the first and second sealing ridges.

Abstract: A check valve includes an upper housing defining an inlet of the check valve, a lower housing defining an outlet of the check valve, and a cavity interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet. The check valve further includes a valve member mounted in the cavity to selectively permit fluid flow in a first direction, and prevent fluid backflow in a second direction opposite to the first direction. The valve member includes a valve body and a valve stem portion extending axially through a central axis of the valve body. The valve member may further include a plurality of feet disposed about and extending longitudinally from an outer circumferential perimeter of the valve body.

Abstract: A check valve includes a housing that includes an inlet port, an outlet port, and a valve chamber. The inlet port extends from a ceiling of the valve chamber to an outer surface of the housing. The outlet port extends from a floor of the valve chamber to the outer surface of the housing. The check valve further includes a valve member supported within the chamber. The valve includes a valve head. When an upstream pressure is applied to the valve, the valve head is configured to deflect away from the ceiling of the valve chamber and unseal the inlet port. When a downstream pressure is applied to the valve, the valve head is configured to deflect away from the floor of the valve chamber and seal the inlet port such that the valve head conforms to a shape of the ceiling of the valve chamber.

Abstract: A dual-chamber syringe may include an end wall and a primary plunger. The primary plunger may include a primary stopper. The primary stopper may form a primary chamber with the end wall. A secondary plunger may be in mechanical association with the primary plunger. The secondary plunger may include a secondary stopper. The secondary stopper may form a secondary chamber with the primary stopper. A primary nozzle may extend from the end wall and may be in fluid communication with the primary chamber. A secondary nozzle may extend from the end wall and may be in fluid communication with the secondary chamber.

Abstract: A check valve may include an upper housing defining an inlet, a lower housing defining an outlet, and a cavity interposed between and defined by the upper and lower housings for fluidly connecting the inlet and the outlet. The check valve may further include a flexible valve member mounted in the cavity to selectively permit fluid flow in a first direction, and prevent fluid backflow in a second direction opposite to the first direction. A filter member may be mounted in the upper housing, upstream of the flexible valve member. The filter member may have an elongated portion configured to maximize surface area thereof exposed to the fluid flow, and restrict passage of undesirable matter in fluid flowing through the check valve.

Abstract: A syringe includes a syringe body, a first plunger, a second plunger, and an inner tube. The syringe body defines a syringe cavity and a syringe port, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger is disposed within the syringe cavity and defines a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The second plunger is disposed within the syringe cavity, the first plunger and the second plunger cooperatively defining a second chamber in the syringe cavity. The inner tube comprises an inner tube lumen, wherein the inner tube and a first plunger shaft lumen of a first plunger shaft define an annulus therebetween, the annulus in fluid communication with a first plunger channel of the first plunger and the annulus permits fluid communication between the syringe port and the first plunger channel.
