  • Patent number: 7875001
    Abstract: A nasal spray apparatus for simultaneously administrating metered amounts of multiple medicaments includes chambers for separately storing incompatible medicaments, such as an antihistamine and a steroid. Reciprocal piston pumps allow the medications to be sprayed into the user's nasal cavity. Two pumps can be used to separately transfer the medicaments to a receptacle where they can be initially mixed just prior to administration. A small volume receptacle is used to reduce the amount of mixture remaining after each stroke of the nasal spray apparatus. A check valve can be associated with each pump to further reduce medicament mixtures from cross contamination within storage chamber preparations. Collapsible components, including collapsible storage chambers or balloon capacitors can be employed to compensate for vacuums and back pressures as the medicaments are pumped to a spray nozzle.

  • Publication number: 20100186739
    Abstract: The present invention relates to a device for the delivery of predetermined doses of liquid medicament to a patient, which medicament is intended to be inhaled by the patient or intended to be injected into the body of the patient. The device is adapted to be in a medicament delivery state and in a medicament non-delivery state. When the device is in a medicament delivery state, said device is adapted to drive a piston into a cartridge containing the liquid medicament to be delivered, with a force that is above or equal to a predetermined minimum force value and below a predetermined maximum force value. The minimum force value is the lowest force value needed to deliver the predetermined dose and the maximum force value is the first force value at which it exists a risk of damaging the cartridge or the components of the device. Further, more of the spring force is brought to an efficient output torque ensuring that a predetermined volume of medicament is expelled from a cartridge.

    Abstract: A multiple use adhesive dispenser facilitates precise, extended dispensing for a surgical procedure by sequentially positioning an ampoule containing a flowable material, such as a polymerizable monomer compound such as a cyanoacrylate adhesive. In one version particularly suited to an open surgical procedure, the ampoules are affixed to a tape substrate that is unreeled from an internal storage reel and transported proximate to an ampoule gripping mechanism with an underlying tape substrate peeled away and internally stored as each ampoule is positioned for dispensing. Actuating an ampoule advancement handle positions the next ampoule and squeezing a movable handle toward a fixed handle effects dispensing. Another version has an elongate shaft that internally augers each ampoule in succession into a pair of spaced jaws that are pinched together by actuating rods to dispense adhesive.

  • Patent number: 6007335
    Abstract: A medicine dispenser adapted to administer liquid medicine via a retromolar pad area including a liquid collecting cylinder body and a soft plastic protective cover. The liquid collecting cylinder body includes a liquid discharge tube extending centrally from a top face thereof. The cylinder body is integrally formed with the liquid discharge tube, the latter having an open end at a top end. The protective tube has an internal hole matching the shape of the liquid discharge tube so that the latter can be fitted entirely into the internal hole of the protective tube. The deepest part of the internal hole of the protective tube is formed with a liquid discharge hole that is substantially at a right angle to the protective tube body so that liquid medicine flowing from the liquid discharge tube can bend at the rear section of the internal hole of the protective tube and out laterally from the liquid discharge hole.

  • Patent number: 5860947
    Abstract: A device for irrigating a wound wherein a syringe fitted with a two-way check valve is filled via a short fill stem that is dipped into irrigant contained in a basin and expelled through a discharge port. The use of a basin allows the irrigant to be positioned immediately adjacent the wound to minimize movement and allows the irrigant to be drawn into the syringe with minimal effort and concentration. The short fill stem minimizes pressure drop and allows the irrigant to be drawn into the syringe as quickly as possible.

  • Patent number: 5816804
    Abstract: A delivery tip for use on a delivery device for applying a dental composition to tooth surfaces includes a tubular member having a proximal end and a distal end. The proximal end of the tubular member is coupled to the delivery device. A plurality of fibrous bristles are disposed on an outer periphery at the distal end of the tubular member. The fibrous bristles can be used in an agitating action to remove entrapped air bubbles from the applied composition such as an impression material. The fibrous bristles on the delivery tip can also be used to coat and spread the composition on tooth surfaces. With the fibrous bristles attached to the outer periphery at the distal end of the delivery tip, the composition can be delivered through the passageway in the tubular member without interference from the bristles.
