Abstract
Medical device flow valves are disclosed herein. A medical device flow valve may include a body defining a first bore extending therethrough, a resilient tube disposed within the first bore of the body and defining a lumen, a neck extending from the body and defining a second bore extending therethrough, and a cap secured to the neck and having a plunger positioned at least partially within the second bore of the neck. The cap is selectively rotatable on the neck effective to selectively adjust the cap between (1) an open position in which the lumen of the resilient tube is substantially uniform and undisrupted by the plunger of the cap and (2) a closed position in which the plunger presses against the resilient tube and substantially closes the lumen of the resilient tube.
Claims20
A medical device flow valve, comprising:
- a body defining a first bore extending therethrough;
- a resilient tube disposed within the first bore of the body and defining a lumen;
- a neck extending from the body and defining a second bore extending therethrough;
- and
- a cap secured to the neck and having a plunger positioned at least partially within the second bore of the neck, wherein the cap is selectively rotatable on the neck effective to selectively adjust the cap between (1) an open position in which the lumen of the resilient tube is substantially uniform and undisrupted by the plunger of the cap and (2) a closed position in which the plunger presses against the resilient tube and substantially closes the lumen of the resilient tube.
A method of delivering fluid in a medical device system, the method comprising:
- securing a first conduit to a first fastener of a medical device flow valve;
- securing a second conduit to a second fastener of the medical device flow valve;
- dispensing a flow of a fluid through the first conduit, through a lumen defined by a resilient tube in a first bore of a body of the medical device flow valve, and into the second conduit;
- and
- adjusting the flow of the fluid from the first conduit to the second conduit through the lumen of the resilient tube by rotating a cap secured to a neck that extends from the body of the medical device flow valve, the neck defining a second bore extending therethrough, wherein the cap including a plunger positioned at least partially within the second bore of the neck and the cap is rotated between at least one of (1) an open position in which the lumen of the resilient tube is substantially uniform and undisrupted by the plunger of the cap, (2) one or more intermediate positions in which the plunger presses against the resilient tube and only partially closes the lumen of the resilient tube, or (3) a closed position in which the plunger presses against the resilient tube and substantially closes the lumen of the resilient tube to adjust the flow of the fluid from the first conduit to the second conduit.
A method of manufacturing a medical device flow valve, the method comprising:
- providing a body defining a first bore extending therethrough, the body including a neck defining a second bore extending from the body;
- positioning a resilient tube within the first bore of the body, the resilient tube defining a lumen;
- and
- securing a cap to the neck to position a plunger of the cap at least partially within the second bore of the neck such that the cap is selectively rotatable on the neck effective to selectively adjust the cap between (1) an open position in which the lumen of the resilient tube is substantially uniform and undisrupted by the plunger of the cap and (2) a closed position in which the plunger presses against the resilient tube and substantially closes the lumen of the resilient tube.
