    Abstract: A vented connector, used with male Luer tip fitting, is disclosed. The connector includes axial and bifurcating portions. The axial portion includes an exterior housing and interior post. The lumen of the post forms a continuum with an air inlet. The air inlet is furnished with a filter or membrane element, selectively allowing for the flow of air to pass therethrough while preventing an outflow of fluids therefrom. The outer diameter of the post is smaller than the inner diameter of male Luer tip fitting. This provides for a fluid flow in-between the exterior surface of the post and the interior surface of male Luer tip fitting; whereas the flow of air that is drawn into the connector from the inlet, passes via the post into the interior lumen of a receptacle, without intermingling with the concomitantly fluid flow from the receptacle.

  • Patent number: 7717881
    Abstract: A medical device for use with a fluid transfer device includes a hub having an open proximal end with a frusto-conically-shaped cavity therein, a distal end and a passageway therethrough. The cavity is part of the passageway. A release element in the passageway of the hub is positioned to block fluid-tight engagement of the frusto-conically-shaped tip with the cavity of the hub. Structure is provided to release at least part of the release element, upon application of a proximally directed force on the hub, to allow the abrupt fluid-tight engagement of the tip and the cavity in the hub.

  • Patent number: 7544189
    Abstract: A needle and hub assembly for an automatic injector and a method for making the needle and hub assembly. The needle and hub assembly comprises a cap or skirt, a forward surface of which is interposed between and reinforced by first and second engaged hub portions. A needle is received in a contiguous channel formed in the two hub portions. The method for making the assembly comprises molding the first hub portion, placing the cap over the first hub portion, inserting the needle into a channel in the first hub portion, and then overmolding or otherwise forming the second hub portion on the exterior of the cap such that it is engaged with the first hub portion. An assembly created by this “two-shot” process can be used to seal a relatively large opening, and supports the needle more effectively than a conventional assembly.

  • Patent number: 7303550
    Abstract: A disposable syringe includes a tubular needle seat inserted into a barrel for fixing a needle cannula. The needle seat has an axially extending cavity with a radially yieldable catch disposed therein. A plunger is movable in the barrel, and has an engaging head defining a rearwardly facing shoulder wall which is retained by the catch when the engaging head is extended into the cavity by a pushing force applied to the plunger. The barrel defines friction diminishing regions such that when the needle seat is moved past the friction diminishing regions to be placed to a disposal position, friction between the needle seat and the barrel is diminished, thereby facilitating a subsequent pulling action of the plunger for retracting the needle cannula into the barrel.

  • Patent number: 7115114
    Abstract: A medical device having a releasable retaining includes needle cannula connected to a hub having an open proximal end with a frusto-conically shaped cavity therein. The cavity is part of a passageway through the hub which is in fluid communication with the lumen of the needle cannula. A retaining element is releasably connected to the hub. The hub includes an aperture and at least one protuberance projecting into the aperture for engaging the frusto-conically shaped tip of a fluid delivery device. The protuberance is shaped to offer less resistance to hub movement in a direction of engagement than in a direction of disengagement with the tip. The retaining element is connected to the hub so that when the hub is engaged to the tip, the force required to disengage the retaining element from the tip is greater than the force required to disengage the retaining element from the hub.

  • Patent number: 6981963
    Abstract: A safety needle-bearing device for mixing and injecting medication from a two-chambered cartridge is provided. The device includes a needle that extends through the forward end of a barrel. A two-chambered cartridge is attached to the barrel and contains components of a medication stored separately in the chambers. A plunger in the rearward end of the cartridge can be advanced into the cartridge to combine the separate components and prepare the medication. As the cartridge is advanced forwardly into the barrel, the medication is injected through the needle and into a patient. At the completion of the injection stroke, the cartridge engages a needle retainer to actuate needle retraction. The needle is subsequently retracted to shield the contaminated needle.

    Abstract: A needleless dosage transfer system for filing medicating devices such as syringes or needleless cannulas to minimize the likelihood of an unwanted needle stick and to avoid the initial cost of a needle as well as the disposal cost of the needle. A vial has a body portion 20 formed with flexibly deformable walls and defines a blind bore. An opening of the vial includes a tapered section adapted to frictionally fit over a taper of a male luer-type fitting commonly found on syringes and needleless cannulas. By deforming the walls of the vial, fluid is forced from the vial into a syringe. The opening of the vial 10 is protected with a cap and includes a scoreline which, when fractured, defines the opening. The cap to be removed from the vial prior to its use is fabricated as one piece with the vial in order to assure sterile conditions during manufacture and filling. A tab is associated with the cap which lists the ingredients within the vial. The vial also supports an area which lists the vial's contents.
