    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.

    Abstract: Syringe assemblies are described herein. A syringe assembly includes an assembly housing, a first syringe, a second syringe, and a connecting gear. The first syringe is disposed within the assembly housing. Each plunger is movable within the respective syringe cavity and defines a respective chamber in the respective syringe cavity, wherein the respective chamber is in fluid communication with the respective syringe port, the respective plunger comprising a respective gear rack extending longitudinally along the respective plunger. The connecting gear is rotatably coupled to the assembly housing. The connecting gear is configured to be in meshed engagement with at least one of the first gear rack and the second gear rack of the syringes.

    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.
