    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 syringe adapter includes a female connector, a body in fluid communication with the female connector, a male connector in fluid communication with the female connector and the body, a passage extending radially through the body and a cannula extending axially through the body and out through the female connector, a first end of the cannula fluidly coupled to an end of the passage disposed within the body. A filter housing containing a filter is fluidly coupled to an end of the passage that is exterior to the body, the filter housing terminating in a vent that is fluidly coupled to the passage. A first fluid path is formed through the cannula, the passage and the vent, and a second fluid path is formed through the female connector, the body, and the male connector, wherein a closed system is provided when the male connector is uncoupled from the medical device.

    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.

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 disclosed drip chamber for an intravenous (IV) therapy system includes a container configured to hold an IV fluid, a drop former suspended over the container, and an inlet port disposed above the drop former and configured to receive the IV fluid from a reservoir. The drop former has an upper end, a lower tip, and an outer surface extending between the upper end and the lower tip. The inlet port is coupled to the outer surface to permit the IV fluid to descend down the outer surface.

    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.
