Resealable conduit and method |
摘要 |
A resealable conduit is used to remove or add fluid to a closed system without coring or contamination of the fluid. The conduit can include funnel-shaped guide means, duck bill valve means and beveled tip puncturing means. A conduit resting angle of less than about five degrees can be achieved. A tip bevel angle between about ten and twenty degrees is preferred. The beveled tip can have a rotated or twisted blade surface extension. A blade surface extension formed with a ninety degree rotation of the blade surface is preferred. Alternately, the puncturing means can include a needle point or a flat cutting surface.
