Patent number: 7811261Abstract: A single-use cover assembly that obscures a substantial majority or an entirety of an injection needle from view before, during, and after an injection procedure. The cover assembly includes a housing and a needle sleeve that retracts and extends by sliding axially within the housing. The needle sleeve carries a locking collar that moves from a first position to a second position once the needle sleeve is fully retracted. In the first position the locking collar allows retraction of the needle sleeve from a fully extended position. In the second position, a portion of the locking collar covers a tip of the needle, thereby preventing retraction of the needle sleeve from the fully extended position.Type: GrantFiled: May 29, 2009Date of Patent: October 12, 2010Assignee: STA-Med, LLCInventors: Sergio Rubinstein, Samuel Kanosky Rosenberg, Russell R.

Publication number: 20100241087Abstract: A needle tip shielding mechanism is described herein. The shielding mechanism comprises an outer housing, an inner housing, and a needle having a needle feature. Generally, the outer housing comprises at least one adapter-interlock feature. Moreover, the inner housing comprises a needle-feature capture mechanism, such as a washer feature, and a needle-tip capture mechanism, such as duckbilled tip barrier. In some cases, the inner housing is slidably moveable within the outer housing. In such cases, the inner housing is movable between a first position that biases the adapter-interlock feature into an engaged position and a second position that allows the adapter-interlock feature to move to an unengaged position. This ability to bias the interlock feature in the engaged position and to allow the interlock feature to move to the unengaged position allows the shielding mechanism to be selectively coupled to and released from an interlock-feature mating component within a catheter adapter.Type: ApplicationFiled: March 19, 2009Publication date: September 23, 2010Applicant: BECTON, DICKINSON AND COMPANYInventor: William G.

Patent number: 7785296Abstract: A needle tip spring protector for a needle having a proximal end, a distal end, and a shaft extending therebetween. The needle tip spring protector includes a spring that circumferentially surrounds a portion of the needle shaft and is restrained in a state wherein its inner diameter is large enough to allow the shaft to move freely within the spring. When the needle is moved to a position in which its distal end is at least partly within the spring, at least one of the ends of the spring releases from restraint such that the spring automatically returns to a state in which its inner diameter is sized so as to grippingly engage the shaft of the needle. Thus, after activation, the spring securely surrounds the distal end of the needle to protect healthcare workers and others from accidental contact with the needle's distal end. When used in conjunction with a catheter assembly, the needle tip spring protector may passively release from the catheter hub after the spring is automatically activated.Type: GrantFiled: July 17, 2008Date of Patent: August 31, 2010Assignee: Smiths Medical ASD, Inc.Inventors: James M.
