    摘要： IV filters are described herein. An IV filter includes a filter housing, a filter media, a filter channel, a priming channel, and a disk valve. The filter housing defines an inlet and an outlet. The filter media is disposed within the filter housing. The filter channel is disposed within the filter housing. The filter channel is in fluid communication with the inlet and the filter media, and the filter media permits flow from the filter channel to the outlet and captures particulate from the flow. The priming channel is disposed within the filter housing. The priming channel is in fluid communication with the inlet and the outlet. The disk valve is coupled to the filter housing. The disk valve is moveable to direct flow from the inlet to the priming channel in a first position and to direct flow from the inlet to the filter channel in a second position.

    摘要： A check valve assembly having a reduced net impact upon hemolysis, where the valve assembly has an elongated valve body including an inlet port, an outlet port, and an internal channel communicating between the ports, with each port disposed about and generally aligned with a central longitudinal axis of the body. The inlet port includes an umbrella-type check valve, and the internal channel is defined by three annular wall portions: a first annular wall portion aligned generally perpendicularly to the longitudinal axis to form a valve seat, a second annular wall potion that is generally concave, and a third annular wall portion that is generally convex, with the first, second and third annular wall portions forming an adjoining and essentially continuously curved, contiguous interior surface which smoothly redirects fluid flow toward the central longitudinal axis of the body and the outlet port.

    摘要： A pressure activated two-way slit valve assembly is designed to be used in combination with, but not limited to, a high flow rate catheter to prevent accidental ingestion of air or loss of blood if the closure cap comes off during non-use of the catheter. In addition, the potential for occlusion of the catheter due to blood clots in the catheter and catheter related infection is substantially reduced. The pressure activated two-way slit valve assembly includes a first end, a second end, a wall defining a dumbbell shaped channel, and a flexible, thin disk having a slit and positioned within the pressure activated two-way slit valve assembly to reside within the dumbbell shaped channel. The slit and the dumbbell shaped channel are sized to enable the slit to deform in response to a predetermined pressure differential across the slit to allow fluid to pass therethrough.

    摘要： A check valve for use in a fluid pathway. The check valve may have a diaphragm and a plurality of supports extending from the diaphragm. The check valve and supports have a line of symmetry, and deformation of the check valve as it moves from a closed position to an opened position can be generally along the line of symmetry.

    摘要： A valve is disclosed, the valve comprising a housing having an first opening and a second opening, and an elastomeric member positioned in the housing, the elastomeric member comprising a thickness, a continuous peripheral wall projecting from the thickness, and a slit extending through the thickness, a continuous portion of the peripheral wall creating a continuous sealable contact with the housing and partitioning the housing into an upper section and a lower section, the elastomeric member configured such that upon creating a pressure differential between the upper section and the lower section of the housing causes either: (i) the peripheral wall to deflect from the housing permitting fluid flow around the elastomeric member; or (ii) the slit to open permitting fluid flow through the elastomeric member. Methods using the valve are also disclosed.
