Abstract
Valve means in a flexible tube, for example, tubing for connecting blood bags, are provided, which comprises a tubular portion having a closed end, and an elongated, generally rigid member, carried on the exterior of the closed end and positioned within the flexible tube. Frangible means are provided to permit the opening of the closed end by manual manipulation of the elongated member from outside of the flexible tube. The elongated, rigid member is adapted to fit in sealing relationship within the tubular portion after opening of the closed end, to permit resealing of the valve. The elongated, generally rigid member carries longitudinal vanes to provide flow channels along its length. In accordance with this invention, a pair of said vanes in opposed relationship extends rearwardly of the end of the central portion of the rigid member, and the flexible tube defines a bore portion position to receive and resiliently hold the proposed veins when the frangible means is broken and the rigid member is separated from the tubular portion. This prevents accidental reclosing of the valve means by the rigid member moving to obstruct the tubular portion.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
