  • Blood collection device
    Patent number: 8425472
    Abstract: A safety needle assembly has a needle hub and a needle cannula projecting from the hub. Wings project transversely from the hub to facilitate manipulation and positioning of the needle assembly. A shield is hingedly attached to the needle hub and can be rotated from a first position where the needle cannula is exposed to a second position where the needle cannula is shielded. At least one latch may be disposed on the shield for secure locked engagement with the hub, the wings and/or the tubing extending from the hub. A spring may also be provided for propelling the shield into the second position.

  • Apparatus for transporting biological samples
    Patent number: 8425864
    Abstract: A container assembly for storing, treating, transporting and stabilizing a biological sample includes a container, a cap and a sample holder removably received in the container. The sample holder can be a platform-like device dimensioned to be supported on a ledge formed in the side wall of the container. The sample holder includes a central cavity for receiving the sample and immersing the sample in the stabilizing agent in the container. In another embodiment, the sample holder has a closure member for closing the open top end of the cavity. The container includes a liquid reagent in an amount sufficient to treat the biological sample. The biological sample is retained in a predetermined containment area of the container to maintain the biological sample immersed in the reagent without regard to the orientation of the container.

  • Passive activated safety blood collection set
    Patent number: 8133207
    Abstract: A shieldable needle device including a needle cannula, a hub, a pair of wings extending laterally from opposing sides of the hub, a tip guard axially movable along the needle cannula from a proximal position substantially adjacent the hub to a distal position, and a drive member is disclosed. The drive member includes a first end connected to the hub and a second end connected to the tip guard and is extendable between a folded biased position and an extended position for moving the tip guard from the proximal position to the distal position. The pair of wings, when in a dorsal position, retain the drive member in the folded biased position maintaining the tip guard in a proximal position. Upon release of the wings, the drive member unfolds, extending the tip guard from the proximal position toward the distal position.

  • Retractable needle assembly
    Patent number: 8109905
    Abstract: A fluid collection or infusion set is provided. The set includes flexible tubing with a fitting attached to a proximal end and a needle assembly attached to the distal end. The needle assembly includes a needle hub and a needle cannula secured in the hub. An actuator arm extends proximally and outwardly from the needle hub and has an actuator button at its free end. The needle assembly is disposed in a barrel and can move from a distal position where the needle cannula is exposed to a proximal position where the needle cannula is shielded. A spring is disposed in the barrel for propelling the needle assembly to the proximal position. The barrel includes an actuating aperture that receives the actuator button for locking the spring in a compressed condition. Depression of the actuator button enables the spring to propel the needle assembly into its proximal shielded position.

  • Fluid collection device having tilting retractable needle
    Patent number: RE43141
    Abstract: A medical device is provided for collecting fluid samples from a patient, such as blood samples. The device includes a needle having a forward sharpened tip that is retracted into the housing of the device after use to prevent exposure to the contaminated needle. The rearward end of the housing is open, forming a socket for receiving a fluid container, such as a vacuum tube, that will receive the fluid sample. A needle retainer releasably retains the needle in the extended position against the rearward bias of a biasing element. After use, the medical professional retracts the needle by pressing an actuation button, allowing the biasing element to displace the needle rearwardly. A guide track guides the needle during retraction, tilting the needle off-axis.

  • Needle safety device
    Patent number: RE43473
    Abstract: A needle assembly includes a needle and a hub mounted to each other. The hub includes a sidewall spaced outwardly from the needle cannula and extending to a distal position between the opposed ends of the needle cannula. A housing integral with the hub defines a sidewall to partially confine a safety shield. The safety shield is slidably disposed about the needle cannula and releasably retained in a proximal position and can be moved to a distal position where the safety shield completely surrounds that portion of the needle hub projecting distally from the hub. The needle assembly includes a spring for propelling the safety shield to the distal position and a latch for releasing the safety shield from the proximal position. The latch may be passively activated by normal usage of the medical implement to which the needle assembly is mounted or alternately activated manually.
