    摘要: A syringe assembly comprises a syringe barrel having an elongated body defining a chamber for retaining fluid, an open proximal end, a distal end and a frusto-conically shaped tip extending from the distal end and having a passageway therethrough in fluid communication with the chamber. The chamber has an inside diameter of at least 13.5 mm. A stopper is in fluid-tight engagement inside the barrel. An elongated plunger rod extends proximally from the stopper through the open proximal end of the barrel. A flange is positioned at the proximal end of the plunger rod. The flange is shaped and positioned to limit the distal motion of the plunger rod in the barrel by contacting the proximal end of the barrel. A tip cap is releasably connected to the tip for sealing the passageway and the chamber contains injectable liquid.

    摘要: A syringe assembly includes a plastic cap (20) that has an end wall (22) and a side wall (24). The end wall (22) preferably includes a plug portion (64) that extends away from an inner surface (62) of the end wall (22). The side wall (24) includes an inner surface (28) that has an engaging portion that sealingly engages a corresponding surface on a syringe. The engaging portion preferably includes two generally annular ribs (34) and (36). An interference fit is provided between the engaging portion and a corresponding surface on the syringe to maintain a sterile seal where the engaging portion contacts the syringe. The plug portion is received within an opening in the syringe and maintains a sterile seal at that point while simultaneously maintaining any medicament within the syringe.

    摘要: A syringe assembly includes a needle sheath that has a cavity that receives a needle cannula. The needle sheath can be formed of materials such as thermoplastic elastomers or plastics yet still be utilized with conventional gas sterilizing processes. The needle sheath includes a passage that permits the sterilizing gases to enter the cavity while preventing entry of microorganisms into the cavity. Thus, a syringe assembly is provided that facilitates sterilizing a needle after the needle sheath has been placed over the needle.

    摘要: A protective sealing barrier for a syringe is disclosed. The protective sealing barrier can be configured to safeguard the sterility of the syringe and any contents held therein, as a barrier against leakage of any contents held within the syringe, or both. The syringe includes a luer tip and a collar having terminal ends which are preferably substantially co-planar with one another. The barrier consists of a membrane which is disposed in substantially entire surface contact with the terminal ends of both the luer tip and the collar. The membrane can be selected from a material permitting the syringe to be irradiated or heat sterilized. Likewise, the membrane can be chosen from a material permitting the syringe to be sterilized by various gas sterilization procedures. The membrane provides good tamper evidence of the syringe, can be stocked in a uniform size adaptable to various sizes of syringes, reduces the storage space required for the syringes, and can serve as a platform for printing information regarding contents held within the syringe.

    摘要: A needle shield assembly of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough. A hub having a proximal end for connecting to a medical instrument and a distal end connected to the proximal end of the needle cannula is provided. A base member is connected to the hub. An elongate needle shield includes a proximal end hingedly connected to the base member, a distal end and a longitudinal axis therebetween. The needle shield includes a longitudinal opening therein. The needle shield is capable of rotating from a first position exposing at least the distal end the needle cannula and a second position wherein the needle cannula is within the longitudinal opening of the needle shield. A sleeve having a longitudinal slot is rotatably connected to the needle shield. The sleeve is capable of rotating about the needle shield to an open position where the longitudinal slot in the sleeve and the longitudinal opening in the needle shield are sufficiently aligned to allow passage of the needle cannula so that the needle shield can be rotated from the first position to the second position. The sleeve is rotatable about the needle shield, to a position which blocks the longitudinal opening of the needle shield. Color safety indicator means for visually indicating the sleeve is rotated to a position which blocks the longitudinal opening of the needle shield is provided.

    摘要: A retractable needle syringe includes a barrel having an inside surface defining a chamber, an open proximal end and a distal end. An elongate plunger is slidably positioned in fluid-tight engagement with the inside surface of the barrel. The plunger includes a distal end, a proximal end and a radially directed projection on its distal end. A movable carrier is positioned in fluid-tight engagement with the inside surface of the barrel. The carrier includes an outside surface, a distal end, a proximal end, and a passageway therethrough in fluid communication with the chamber. The proximal end of the carrier includes an open-ended groove which is sized and shaped to receive the plunger projection. The groove includes an axial portion and a circumferential portion. The plunger is movable axially so that the plunger projection can enter and exit the axial portion of the groove. Rotation of the plunger with respect to the carrier causes the projection to enter the circumferential portion of the groove, containing said projection so that said plunger rod can apply axially directed force and rotationally directed force to the carrier. A needle cannula projects outwardly from the distal end of the carrier. Control structure is provided to prevent movement of the carrier with respect to the barrel during normal use of the syringe and for allowing the carrier to be moved proximally into the chamber of the barrel through forces applied to the plunger.
