  • Patent number: 7207975
    Abstract: A needle stick protection device includes a housing and a locking member positioned within the housing to permit the selective locking of the needle relative to the housing. The locking member includes a spring biased strip having first and second upwardly extending arms connected by a central base member. The first and second upwardly extending arms are biased relative to each other and respectively include a first needle aperture and second needle aperture. A release member is associated with the locking member for facilitating the controlled release of a needle locked in position by the locking member. The release member engages the first upwardly extending arm and the second upwardly extending arm such that selective movement of the release member causes the first and second upwardly extending arms to move between a first locking position and a second release position.

  • Patent number: 7189217
    Abstract: A skin puncture device for use as an intravenous catheter or blood collecting needle set is provided with a mechanism for protection against needle injury and access to fluid passageway during insertion. The assembly includes a flexible extension tube connected to the proximal end of the needle housing for use in difficult insertion sites. The extension tube provides access for fluid injection so that the passageway and needle can be filled with fluid prior to needle/catheter insertion, allowing diffusion of blood to provide evidence of successful venipuncture and allowing the infusion of small amounts of fluid into the vein to facilitate catheter advancement. The locking mechanism consists of two apertures in the needle housing and two pairs of needle guard locking tabs which selectively engage when the needle guard is pushed forward to its fully extended position upon completion of insertion or blood drawing, encapsulating the length of the needle.

  • Patent number: 7163526
    Abstract: The needle assembly is provided with the housing, an IV cannula for accessing a blood vessel and a non-patient cannula for communication with an evacuated tube. A flashback chamber is provided in the housing at or near the distal end of the housing. A shield is hinged to a portion of the housing proximally of the entrance to the flashback chamber. As a result, good visibility of the flashback chamber is achieved. After use, the shield can be rotated into a closed position for surrounding the IV cannula and avoiding accidental needle sticks.

  • Patent number: 7147623
    Abstract: The invention relates to a medication infusion set of the type having a flexible cannula adapted for subcutaneous placement, in combination with an insertion, or puncturing, device comprising an insertion needle extending through the cannula and beyond the outer tip thereof, the insertion device further comprising a shield adapted to cover the insertion needle when the latter is withdrawn from the cannula. More specifically, the invention provides a fully integrated shield member having a position in which it covers the cannula and the needle when the insertion device is connected to the housing, a position allowing the cannula to be inserted when the insertion device is connected to the housing, and a position in which the shield covers the needle and the outer tip thereof when the insertion device has been removed from the housing. By this arrangement the need for a separate cover to protect the needle prior to use can be dispensed with.

  • Patent number: 7108678
    Abstract: A captive cover for a hypodermic needle of an IV tube assembly has an elongated body connected to an element of the IV tube assembly. The elongated body is hollow and has a proximal opening, a closed distal end, a chamber, at least one locking tab and one or more optional connectors. The hypodermic needle of the IV tube assembly can be inserted through the proximal opening into the chamber. A flange on the hypodermic needle of the IV tube assembly is held in the captive cover by the locking tab. Since the hypodermic needle of the IV tube assembly only passes through the locking tab of the elongated body, the hypodermic needle of the IV tube assembly can be conveniently inserted into the elongated body. The captive cover can accommodate an ordinary hypodermic needle and has a simple structure.

  • Patent number: 7083600
    Abstract: A safety needle includes a needle with a sharp end and a needle shield. The needle shield includes collapsible interlocking members, wherein one member is an end member with a hole surrounding the needle, a spring inside the collapsible interlocking members that applies an expanding force on the collapsible interlocking members, a releasable latch structure that retains the collapsible interlocking members in a collapsed state, wherein when the releasable latch structure is actuated the collapsible interlocking members expand and enclose the sharp end of the needle, and a closing structure that prevents the sharp end of the needle from exiting the hole after the collapsible interlocking members enclose the sharp end of the needle.

  • Patent number: 7041086
    Abstract: A safety structure for a needle of a syringe including an external bushing connected with a base, and a barrier structure on the base contacts with the needle, which has an extended bushing on a base frame. At the front end of the bushing there is an extended cannula with an outer edge through which a needle is inserted. The external bushing is made of soft materia. A trocar boring on a front end of the base is connected with the trocar-admitting part. Moving the barrier structure away from the needle and pushing the base back, the trocar boring of the base covers outside of the outer edge of the needle. The base is fixed on the needle by friction between a wall of the trocar boring and the outer edge of the cannula.

  • Patent number: 7029461
    Abstract: A medical needle shield apparatus is provided which includes an extensible shield having a first segment and a second segment extending therefrom. The second segment includes an opening configured for clearance of a medical needle of a medical needle device during attachment of the extensible shield to the medical needle device. The second segment defines a planar surface adjacent a distal portion thereof. The planar surface is configured to engage the needle for disposing the shield in an extended position. In alternate embodiment, the medical needle shield apparatus has a syringe having a needle hub supporting a needle. The first segment articulates from a collar disposed about the needle hub. The collar includes a pair of latches. The opening is configured for travel about the needle to facilitate extension of the shield from a retracted position to an extended position. The second segment further includes a proximal fulcrum that engages the needle to facilitate extension of the shield.

  • Patent number: 7004927
    Abstract: A medical needle shield apparatus is provided that includes a shield that is extensible from a retracted position to an extended position to enclose a distal end of a needle. A binding member is disposed within the shield and defines binding surfaces that form an aperture configured for slidable receipt of the needle between the retracted position and the extended position. The binding member includes at least one drag-inducing member extending therefrom that is configured for slidable engagement with the needle between the retracted position and the extended position such that the at least one drag-inducing member engages the needle to create a drag force with the needle. The drag force causes rotation of the binding member relative to a longitudinal axis of the needle such that the binding surfaces engage the needle to prevent slidable movement of the needle in the extended position of the shield.

  • Patent number: 6997901
    Abstract: A single use syringe (10) includes a needle (18), barrel (16), plunger assembly (20) and shield (12). The barrel (16) bears a locking member (26) which encircles the front end of the barrel (16) and is carried forward by the barrel (16) to a position where it engages the shield (12) and is retained by the shield (12) such that the locking member (26) is separated from the barrel (16) as the barrel (16) is withdrawn rearwardly after use. The locking member (26) is resilient and, after it is removed from the barrel (16), assumes a configuration which prevents subsequent forward movement of the barrel (16) within the shield (12). The barrel includes a frangible seal (30) which is broken by rearward movement of needle mount (32). The shield (12) includes a shield extender (14) for controlling the depth of penetration of the needle. The syringe can also be used to inject medicament into a IV bag via a male port as shown in FIG. 7.
