One-way valve devices can be used within fluid systems. For example, this document provides one-way valves that can be installed within a lumen of a tube, a fitting, and other types of tubular members. In some embodiments, the one-way valve includes a unitary frame and a ball member that is loosely constrained within the confines of the frame.

1. A one-way valve device comprising: a frame, the frame including a base that defines an opening and a seat, the frame also including a plurality of elongate ball containment members that extend from the base, each ball containment member of the plurality of ball containment members having a free end that is opposite of the base, wherein the frame is a unitary, monolithic construct; a spherical ball, the ball loosely disposed within and contained within a space defined between the plurality of ball containment members and the base, wherein the ball can make contact with the seat to create a fluid seal therebetween; andan insertion tool,wherein the one-way valve device is configured to be inserted within the lumen of a tube, wherein the one-way valve device is sterile and contained within packaging that maintains sterility, and wherein the insertion tool is contained within the packaging. 2. The one-way valve device of claim 1, wherein the base includes one or more annular ribs that are configured to engage with an inner wall of the tube. 3. The one-way valve device of claim 1, wherein the frame is a unitary molded thermoplastic component. 4. The one-way valve device of claim 1, wherein the insertion tool comprises a insertion tool base and a plurality of fingers extending from the insertion tool base, wherein free ends of the plurality of fingers are configured for contacting the base of the one-way valve device and for applying a force thereto for inserting the one-way valve device within the tube. 5. The one-way valve device of claim 1, wherein the plurality of elongate ball containment members comprises three elongate ball containment members. 6. The one-way valve device of claim 5, wherein the three elongate ball containment members are oriented at 120 degrees apart from each other around the base. 7. The one-way valve device of claim 1, wherein the ball is free to move within the space along a longitudinal axis of the frame. 8. The one-way valve device of claim 1, wherein the ball is made from polymeric, ceramic, natural, or metallic materials. 9. The one-way valve device of claim 1, wherein the frame comprises a sleeve sized to couple within an end of a barbed tube. 10. A one-way valve device comprising: a valve body, the valve body defining a lumen longitudinally therethrough, the valve body including a sleeve portion on one end of the valve body, the sleeve portion configured for engaging within a lumen of a first tube, the valve body also comprising an annular rib for engaging with an inner wall of a second tube when the one-way valve device is installed within a lumen of the second tube, and wherein the second tube is configured to be installed over an end portion of the first tube while the one-way valve device is within the lumen of the second tube and the sleeve portion is engaged within the lumen of the first tube; anda duckbill member at least partially disposed within the lumen of the valve body, wherein the duckbill member is reconfigurable between an open configuration and a closed configuration. 11. The one-way valve device of claim 10, wherein the duckbill member is a flexible elastomer. 12. The one-way valve device of claim 10, wherein the one-way valve device is sterile and contained within packaging that maintains sterility. 13. The one-way valve device of claim 10, wherein the valve body is a unitary molded thermoplastic component.
