  • Patent number: 9504786
    Abstract: A safety shield apparatus is provided that includes a housing that defines a cavity. A distal end of the housing includes a cover having a movable tab. A hub is disposed for movement within the housing and includes a needle having a distal end and a movable projection. The hub is biased between an extended position, such that the distal end of the needle is exposed and the movable projection is releasably disposed with the cavity, and a retracted position whereby the distal end of the needle is disposed within the housing. The movable tab is engageable with the movable projection to release the movable projection from the cavity to facilitate movement of the hub. The distal end of the housing may define a lip that is configured to capture the distal end of the needle. The hub can define an angled distal surface to orient the needle out of axial alignment with the housing and into capture with the lip.

  • Patent number: 4967919
    Abstract: A blood collection assembly is provided for blood collection tubes, and more particularly for evacuated blood collection tubes, whereby the potential exposure of laboratory technicians or hospital personnel to potentially infectious blood specimens is reduced. The device consists of a cap which is configured to be placed over and fitted onto the rubber stopper of an evacuated collection tube. The top surface of the cap includes a centrally located bore section which is surrounded by a downwardly directed retaining ring to prevent accidental exposure of the user to the upper flange portion of the stopper wherein the user is protected from exposure to the contaminated bottom surface of the stopper as the cap and stopper are removed from the collection tube.
