  • Patent number: 4943283
    Abstract: An apparatus for collecting blood or other body fluid from a donor, in which a length of tubing has a first needle on one end for insertion into the vein of a donor, and a frangible joint between the ends of the tubing to separate the length of tubing into first and second parts. The frangible joint includes a combination needle shield and test tube receptacle on one end of the first part, disposed coaxially to a second needle used to fill test tubes with material drawn through the first needle. The combination shield and test tube receptacle is adapted to receive a test tube therein for operative relationship with the second needle so that the test tube may be filled with the material. A second shield is slidable on the tubing and has a retracted position adjacent the frangible joint and an operative position extended over the first needle when that needle is withdrawn from the vein.

  • Patent number: 4935011
    Abstract: A multi-panel shield or sheath constructed to define an envelope into which an intravenous needle having a sharpened cannula may be withdrawn upon removal from a vein. The envelope has a compression flap adapted to overlie the venipuncture site while the needle is being withdrawn from the vein, whereby a nurse, doctor or other person using the device may exert pressure on the venipuncture site as the needle is being withdrawn. A gripping panel is also provided to facilitate holding of the sheath as the needle is being retracted into the envelope. After the needle has been withdrawn into the shield envelope, the panels may be folded over one another to completely enclose the needle for subsequent handling and/or disposal. In some embodiments of the inventions a non-folding sheath defining an envelope is utilized. Other embodiments have no compression panel.
