摘要： A valve comprises a flexible member including a slit formed on a central portion thereof and a first housing defining a first lumen extending therethrough, the first housing including a first contacting surface adapted, when the slit of the flexible member is aligned with the first lumen, to contact a first side of the flexible member the first housing defining a relief area extending about a perimeter of the first contacting surface radially outside the central portion relative to a longitudinal axis of the first lumen in combination with a second housing adapted to mate with the first housing with a second lumen defined by the second housing aligned with the first lumen and separated therefrom by the flexible member, the second housing including a second contacting surface which, when the first and second housings are mated to one another in an operative configuration with the flexible member pinched therebetween, contacts a second side of the flexible member opposite the first side thereof along the longitudinal axis, a radially outer portion of the second contacting surface including a protrusion aligning with and extending into the relief area when the first and second housings are mated in the operative configuration, the protrusion bending a peripheral portion of the flexible member about a radially outer edge of the first contacting surface into the relief area to maintain the flexible member at a desired position separating the first and second lumens so that, when subject to a fluid pressure of at least a predetermined magnitude, the slit of the flexible member opens to permit fluid transfer between the first and second lumens and, when subject to a fluid pressure less than the predetermined magnitude, the slit of the flexible member remains closed preventing fluid transfer between the first and second lumens.
