  • Patent number: 6551287
    Abstract: A needle protection device for a vial has a collar at the base of which a number of finger grippers extend. The collar is placed about the hub of a vial and pushed therealong until the gripper fingers snap over the bottom surface of the needle hub so as to fixedly couple the collar to the needle hub of the vial. Flexibly extending from the collar is a housing that is pivotable to a position in alignment along the longitudinal axis of the vial for enveloping the needle, to thereby prevent the needle from being exposed to the environment. A hook integrated to the inside of the housing ensures that the needle and the housing could no longer move relative to each other once the hook snaps over and traps the needle, as the housing is pivoted to its alignment position. For those vials that have a needle hub that extends smoothly from the vial, a second embodiment of the instant invention has, in place of the collar, a base that has two extending arms with coacting ends.

  • Patent number: 5485854
    Abstract: A blood collection assembly is disclosed in which the tube holder to which the contaminated end of a blood collection cannula is inserted. To prevent any contaminated blood from being exposed to the user, or bystanders, an elastic pierceable sheath is fixedly aligned within the tube holder so that the tip and at least a portion of the cannula, when fully inserted to the tube holder, are enveloped within the sheath. Any blood dripped from the cannula is therefore retained within the sheath. To obtain samples of blood for testing, a VACUTAINER tube is inserted to the opposite end of the tube holder. The rubber stopper at the top of the VACUTAINER, upon insertion, would slidably push the closed end of the sheath toward the tip of the cannula so that the former is pierced by the latter.

  • Patent number: 5277311
    Abstract: The needle assembly holder of the present invention has mounted about its receptacle end a rotatable safety sheath so that irrespective of how the tip of the cannula of the needle assembly is oriented with respect to the holder, the user can nonetheless obtain an unobstructed view of the tip of the cannula by rotating the safety sheath out of her line of sight. Friction drag is provided between the receptacle end of the needle assembly holder and the safety sheath so that the safety sheath would not freely rotate about the needle assembly holder absent a rotation force applied thereagainst.

  • Patent number: 5232455
    Abstract: To provide a high degree of protection against the possibility of someone being accidentally punctured by a contaminated needle, the syringe of the present invention has directly connected thereto a protective housing, which can be pivoted to a position in alignment with the contaminated needle to envelop the same. As the housing is pivoted into the alignment position, locking mechanisms integral of the housing would fixedly retain the needle within the housing. The syringe of the present invention may be modified to include a housing containing an integral collapsible section and a sealer adapted to the distal portion of the housing such that, upon collapse of the collapsible section of the housing, the tip of the contaminated needle would penetrate into and be sealingly secured by the sealer. Another modification of the syringe of the present invention involves utilizing a collapsible hinge to connect the protective housing to the main body portion of the syringe.
