ABSTRACT:
A blood collection device wherein a double-ended cannula is retracted within the barrel of the device for storage and disposal. The cannula is attached to the device immediately prior to use by being threaded into an aperture formed in a movable disc disposed within the barrel and rotated to a locked operating position for attachment of the cannula and use. After use, the disc is counter-rotated to permit the cannula, mounted to the disc, to be longitudinally retracted completely within the barrel to a position in which the cannula is permanently locked by stopping the disc against further movement. The disc aperture is threaded in the same direction as it is rotated to the operating position to avoid moving the disc out of the locked position during attachment of the cannula to the device.
