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: Syringes are described herein. A syringe includes a syringe body, a first plunger, a biasing member, and a priming indicator. The syringe body defines a syringe cavity, a syringe port, and an indicator window, wherein the syringe port is in fluid communication with the syringe cavity. The first plunger comprises a first plunger shaft extending from the first plunger, the first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity, wherein the first chamber is in fluid communication with the syringe port. The biasing member couples to the first plunger shaft, wherein the biasing member urges the first plunger from an unprimed position to a primed position toward the syringe port. The priming indicator presents the first indicator portion through the indicator window in the unprimed position and presents the second indicator portion through the indicator window in the primed position.

Abstract: Check valve assemblies for fluid flow sets and devices are provided. The check valve assembly includes a housing having an inlet body and an outlet body. The inlet body includes a fluid inlet, a first seal bead having a first height, a second seal bead having a second height and a central channel. The outlet body includes a fluid outlet and a stem having a centering post, the centering post received by the central channel of the inlet body. A seal has an inner ring with a first thickness and an outer ring with a second thickness less than the first thickness. The inner ring is engaged with the first seal bead and the outer ring is engaged with the second seal bead in a fully sealed position of the check valve assembly. Fluid flow sets and methods for manufacturing check valve assemblies are also provided.

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 method of manufacturing a check valve may include forming an upper housing as cylindrical body with (i) an internal surface including an upstream internal surface and a downstream internal surface having a projection and (ii) an external surface, forming a T-shaped filter member and mounting the T-shaped filter member in the internal surface of the upper housing. The method may further include forming a lower housing with a support portion at a central portion thereof, mounting a flexible valve member on the support portion, and coupling the upper housing with T-shaped filter member mounted therein onto the lower housing with flexible valve member mounted therein such that the T-shaped filter member is disposed upstream of the flexible valve member.
