    Abstract: The present invention includes methods for artificially inseminating animals using an improved artificial insemination device that prevents contaminants from entering the opening at the end of an insemination sheath during insertion through the reproductive tract of an animal. A thin protective cover or membrane is provided at the tip of the sheath to seal it, the membrane being designed to rupture under the pressure from the seminal fluid being applied by the plunger used to eject the semen from the insemination gun. The protective cover can be an integrated portion of the sheath itself, or a material applied to the tip of the sheath. The protective cover is minimal in size as to not increase the diameter of the artificial insemination device so that there is no loss in tactile sensitivity to the breeder who must maneuver the invention through the animal's reproductive tract.

    Abstract: A pivotable shielding needle device for shielding used needle cannulas. The device generally includes a hub with a needle, and a shield pivotable between a first position exposing the needle and a second position encompassing the needle. A biasing element acts on the shield to pivotally bias it toward the second position, with the shield maintained in the first position through a latch mechanism extending between the shield and the hub. A release arrangement extends from the hub and is squeezable to cause movement of a movable member which releases the latch mechanism, thereby causing the shield to be pivotally biased to the shielding position. Accordingly, activation and shielding of the needle can be effectively accomplished during removal of the needle device from a patient, thereby providing for passive activation of the device during normal use.

  • Patent number: 7125397
    Abstract: Protective devices for injection needles or infusion needles that include a needle holder at a proximal end of the needle, on whose shaft a protective element for the needle tip can be positioned and moved, are herein disclosed. The protective element is configured to block the needle tip following an injection to prevent accidental contact therewith. The protective element may be positioned on the shaft in a ready to use position inside a grip part or middle retaining portion, which is also used to activate the protective element over the needle following the injection.

  • Patent number: 7125398
    Abstract: The present invention provides a needle guard comprising a base having a needle well to guide the point of a needle into the patient and, at the same time, for confining the pointed end of a needle within the walls of the needle well until the needle is inserted into a patient. The base is connected by at least a connector to a handle. The connector is constructed to allow the needle to be pushed beyond the needle well thereby exposing the needle. The connector also limits the extent to which the needle can be retracted. This prevents the needle from being pulled past the needle well as the needle is extracted from the patient. As a consequence of the construction, the point of the needle is substantially maintained within the needle well, except when the needle is inserted into the patient.

  • Patent number: 7112191
    Abstract: A needle safety device for an intravenous catheter apparatus that includes a base capable of receiving a needle into opposing jaws attached to the base and capable of being influenced by the needle. The jaws move between an expanded position which interact with an obstruction within a wing housing of the intravenous catheter apparatus. The jaws permit relative movement of the needle with the base when expanded, close around a needle tip as it passes the jaws, and prevent relative movement of the needle with the base when the jaws are collapsed. The needle of the intravenous catheter apparatus may then be safely disposed with the needle tip within the needle safety device.

  • Patent number: 7112190
    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.

  • 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: 7108682
    Abstract: The present invention protects a distal portion of a catheter during shipment and storage. The device holds the distal portion suspended such that it does not contact the device. The suspended portion is protected from damage resulting from abrasion. When the suspended portion includes a therapeutic coating, the coating is protected from the risk of impaired performance resulting from a therapeutic agent migrating out of the coating and into the packaging material or components of the packaging material migrating into the therapeutic coating, both of which can occur if a therapeutic coating remains in contact with another material for an extended period of time.

  • Patent number: 7063683
    Abstract: A non-mechanical needle guard for permanently securing and incapacitating a single used syringe and needle assembly consists of a sleeve for receiving the needle and luer lock and the hub end of a syringe. The sleeve contains a two part adhesive, the two elements being separated by a penetrable membrane, with the opened end of the sleeve being sealed by a second membrane. A stand holds a number of the needle guards in a stable, upright position so the needle may be inserted with a single hand, as required by OSHA. As the needle penetrates the two membranes, the two elements of the adhesive combine, permanently securing the needle and syringe end in the cured adhesive. The needle guard of the present invention secures and incapacitates the used needle and syringe in a manner meeting OSHA's disposal safety standards.

  • Patent number: 7060055
    Abstract: The present invention is directed to a shieldable blood collection set as well as a needle assembly for use therein. The needle assembly includes a needle cannula having a puncture tip at a distal end thereof and a hub which supports the needle cannula. A hollow outer shield co-axially surrounds a distal end of the hub and has an inner surface which is in cooperating engagement with an outer surface of the hub. The hub includes a first tab extending outwardly at a position which is exposed from the outer shield, and the outer shield includes a second tab. The first tab and the second tab are configured such that opposing forces applied against the tabs cause the outer shield to move from a retracted position in which the puncture tip of the needle cannula is exposed, to an extended position in which the outer shield covers the puncture tip.

  • Patent number: 7037292
    Abstract: A safety shield apparatus is provided that includes a housing that defines a cavity. A distal end of the housing includes a cover having a movable tab. A hub is disposed for movement within the housing and includes a needle having a distal end and a movable projection. The hub is biased between an extended position, such that the distal end of the needle is exposed and the movable projection is releasably disposed with the cavity, and a retracted position whereby the distal end of the needle is disposed within the housing. The movable tab is engageable with the movable projection to release the movable projection from the cavity to facilitate movement of the hub. The distal end of the housing may define a lip that is configured to capture the distal end of the needle. The hub can define an angled distal surface to orient the needle out of axial alignment with the housing and into capture with the lip.
