  • Patent number: 5533973
    Abstract: An apparatus and method are disclosed for modifying a liquid enteral nutritional product during delivery thereof from a supply to a feeding tube delivering the modified liquid enteral nutritional product to the gastrointestinal tract of a patient. At least one beneficial agent not in controlled release dosage form in a useful, dose unit, amount, is disposed within a formulation chamber so as to be taken up in a liquid enteral nutritional product traversing the formulation chamber while feeding the modified nutritional product into the gastrointestinal tract of a patient. The beneficial additive(s) are selected from nutrients, medicaments, probiotics, or diagnostic agents, or mixtures thereof, each in a dosage form that is dispersible in the medium of the liquid enteral nutritional product in less than two hours.

  • Patent number: 5531683
    Abstract: A device for intermixing a first component, such as a parenteral fluid with a second component, such as an immobilized drug carried by a scaffold to form a beneficial agent which, following the mixing step, can be dispensed directly from the device for infusion into a patient. The device includes novel mechanisms for mateably interconnecting a container, such as a glass vial containing the first component with a housing having a fluid outlet which houses a sealed container containing the second component, and then for controllably mixing the components under sterile conditions to form an injectable solution which is automatically dispensed through the fluid outlet of the device.

  • Patent number: 5520657
    Abstract: A syringe is disclosed having a large syringe housing which can be fitted with a large needle holder which in turn holds a large introducer needle. The introducer needle defines a passageway. A small seeker needle which is designed to fit within and through the passageway of the large introducer needle is attached by way of a small needle holder to a small syringe housing. A washer adapter attaches to the front of the small needle holder in order to have the small syringe housing move within a large syringe housing as a plunger for the large syringe housing. The small syringe housing in turn receives on one end a small syringe plunger which may define a small plunger lumen or chamber which can be used for transduction. Another embodiment has a modified needle having a port in the shaft within the syringe to allow sampling.

  • Patent number: 5514113
    Abstract: A syringe and adapter are constructed so as to provide a bend in the hypodermic needle allowing a dentist to reach hard to get to places inside the mouth. With a bend in the needle, the dentist can rotate the body of the syringe to point the needle in various directions while the body of the syringe is placed inside the mouth. Around the bend of the needle is a solid material to prevent the needle from breaking about the bend while in use.

  • Patent number: 5514107
    Abstract: A safety syringe adapter (4) has a hollow body (26) sized to house a cartridge-needle unit (6) to which a carrier (24) is fixed. The cartridge-needle unit and carrier therewith are movable from a use position, with the needle tip (58) exposed, to a safe disposal position, with the needle tip within the body. A stem assembly (28) has an elongate stem (60) and a coaxial tubular stem extension (64) and is movable to a post-injection position, at which the stem extension becomes secured to the carrier. Pulling the stem assembly proximally causes the cartridge-needle unit to move to its safe-disposal position so the needle tip is within the body for safe disposal.

  • Patent number: 5512049
    Abstract: Disposable syringes are marketed with a plastic cover which protects the needle assembly inserted within. Typically, the end of the cover that extends towards the barrel of the syringe is designed with a surrounding lip. The holder of the invention is fixed to a surface or stand to receive the cover and grasp, secure or envelop its surrounding lip. In use, the syringe, with its cover, is placed into the holder, slid to one side for the lip of the cover to be grasped, and then the syringe and needle assembly can then be safely pulled away from the cover. To dispose of it, the syringe is reinserted into the grasped cover, then slid with the cover out of the grasp of the holder to the other side, where a pair of nibs are provided to limit its movement and allow for the syringe, with its cover in place, to be lifted out. The holder of the invention makes almost impossible any accidental jabbing of one's fingers or hand in removing the needle assembly from, or inserting it back into, the syringe cover.

  • Patent number: 5499972
    Abstract: An ampule containing a liquid, e.g., a dose of medicine, connects to a hand-held portable power unit containing an energy accumulator which can be charged and then discharged by manual actuation of a trigger. Preferably the energy accumulator is a compressible spring which is charged by compressing it and discharged by releasing it. The discharging accumulator powers a thruster, preferably a rod, driving it against a plunger in the ampule. The driven plunger applies pressure to the liquid in the ampule and drives the liquid through a small tapered orifice having an open mouth. During an injection, the open mouth of the orifice is pressed against an injection site so that the liquid being forced through the orifice can hypodermically penetrate the injection site. The preferred compressible spring can be charged by forcing the thruster backward against the spring, compressing it to a point where a latching device catches it and holds it compressed.

  • Patent number: 5498248
    Abstract: An iontophoretic structure for medical devices is provided that uses controlled electrical current derived from two dissimilar galvanic materials to drive oligodynamic metal ions into solution to kill bacteria on and near the device to which the structure is affixed. In one embodiment, a first galvanic material separated from a second galvanic material by a resistive material produces an anti-bacterial current flow when placed in contact with an electrolytic fluid. In another embodiment, a cylindrical elastomeric catheter incorporates a first and a second galvanic material separated by a resistive material which controls a current flow between the galvanic materials when the catheter is immersed in an electrolytic fluid. The galvanic materials can be dissimilar metal powders embedded in a conductive polymer substrate that forms an iontophoretic composite material, or dissimilar metals arranged in layers separated by a resistive layer.

  • Patent number: 5498243
    Abstract: A magnifying syringe shield including a hollow sleeve, a needle shield, and a snap ring. Radially extending projections, provided on the hollow sleeve, slide within longitudinally extending slots in the needle shield, allowing extension and retraction of the needle shield. The snap ring is positioned within a groove in the hollow sleeve at retraction, and extends into a groove in the needle shield at extension. Extension of the snap ring into the groove in the needle shield locks the shield in the extended position over the syringe needle. The needle shield further includes a magnifying arrangement for enlarging the dosage indicia imprinted on the housing of an enclosed syringe.

  • Patent number: 5496272
    Abstract: An artificial insemination and embryo transfer device comprises an elongate hollow tube, and a hollow straw containing a reproductive organism therein and fitted in the elongate tube. A flexible tip is secured to an end of the elongate tube and engaged with the straw. The tip has a passage in communication with the straw and a conical portion adapted to smoothly pass it through a cervical canal of a female subject. A piston rod is slidably mounted in the elongate tube and constructed to enter into the straw so as to discharge the reproductive organism contained in the straw through the passage of the tip by its axial advancement. A locking element is disposed between the elongate tube and the piston rod for restraining a free axial movement of the piston rod within the elongate tube. A first enclosure is inserted around the elongate tube so as to protect the elongate tube against contamination from infectious materials in the cervical canal during the passing of the device through the cervical canal.
