Having Structure For Facilitating Sterilization Of Syringe Or Preventing Contamination Of Material Therein Patents (Class 604/199)
  • Patent number: 11911588
    Abstract: Described herein are syringe caps including a plug portion and a protruding member extending from one end of the plug portion. The protruding member can extend a length greater than a depth of an accumulated component in the syringe. Also described herein, are systems including a syringe containing a composition and a syringe cap. The syringe cap can include a luer-lock with a projecting member that projects into the syringe. The projecting member can assist in creating a tunnel through the accumulated material thereby allowing degassing of the composition. The projecting member can also help to prevent accumulation of a radiopaque visualization agent or contrast agent that may accumulate along one end of the syringe.

  • Patent number: 8715231
    Abstract: A hinged cap device for use with a syringe includes a base defining an interior cavity for mounting onto a tip and a cap connected to the base by a living hinge. The cap is moveable from a ready position to an open position to expose a needle, and from the open position to a secured position to prevent relative rotation between the cap and the base. A first latching mechanism is on the cap for engaging the needle, the first latching mechanism locatable on a first side of the needle in the ready position and locatable on a second side of the needle in the secured position. The needle is disengageable from the first latching mechanism in the ready position, and the needle is not disengageable from the first latching mechanism in the secured position.

  • Patent number: 8708970
    Abstract: An injection needle assembly is presented having a tubular needle holder with distal and proximal engagement means, a tubular cap having proximal inner and outer engagement means, a tubular needle cover having a first engagement means arranged to cooperate with the proximal engagement means, and second engagement means arranged to cooperate with the proximal outer engagement means of the cap. The needle cover is arranged to be displaced from a first position wherein the second engagement means and the proximal outer engagement means prevents the needle cover and the needle holder to be axially displaced by a linear displacement, to a second position wherein the needle cover and the needle holder are distally displaced. The proximal inner engagement means of the cap and the distal engagement means of the needle holder prevents the needle holder to be proximally displaced but allows the needle cover to be distally displaced.

  • Patent number: 8628501
    Abstract: A sterilization cap carried on a needle support end of a syringe. The cap includes a main body having first and second ends, the first end being connectable to the needle support end, as well as being connectable onto the needle support end alone of a primary or IV extension line. A sponge secured within a sponge cavity within the second end is saturated with a sterilizing liquid. A removable cover attached to the second sealingly encloses the sponge until the syringe is used. The second end is sized, when the cover is removed, to fit over a tip of a CLAVE needleless connector extension or IV tubing a distance sufficient to compress the sponge to sterilize the tip with sterilizing liquid expressed from the sponge.
