Abstract:
PROBLEM TO BE SOLVED: To provide a pump-type dispenser for dispensing a medicament in droplets or in spray form. SOLUTION: The dispenser includes a rigid vial, an extendable pouch in the vial, a nasal screen, a one-way actuation mechanism, a one-way valve mechanism in a nozzle area, and a spring member. The valve mechanism and the spring member are incorporated in a pump body. The screen aligns the nozzle to the nasal passage, and hides the nasal area from public view. The valve mechanism moves the medicament from the dispenser in one direction, thereby preserving sterility of the medicant without using a preservative regardless of the surrounding environment. A user can load a uniform amount of the medicament with a uniform actuation force and dispense at a uniform speed via a single continuous motion of the actuation mechanism upon application of a very small force on an actuation trigger mechanism. By preventing the pump mechanism from being left in a loaded state for a prolonged period of time, the spring mechanism is hardly fatigued. The combination of the vial and the pouch facilitates a long term use as well as a uniformity of dosage independent of the pump orientation. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
A medicament-dispensing system includes a cartridge for housing and actuating an accordion-like vial-dispenser for dispensing a calibrated amount of medicament by means of a single actuation motion which sequentially loads the vial-dispenser and dispenses the loaded medicament. The vial-dispenser has a front bellows portion, a rear bellows portion, an internal piston mechanism, a medicament storage chamber and a dosage cavity. The cartridge has a trigger mechanism which acts in concert with a notched lever and a wedge-shaped arm internally located in the cartridge to sequentially load the dosage cavity with medicament and discharge it. Depression of the trigger mechanism simultaneously extends, by means of the notched lever, the front bellows portion and compresses the rear bellows portion to load the dosage cavity with medicament. Once the notched lever has extended the front bellows portion a predetermined distance, the notched lever is disengaged from the front bellows portion by the wedge-shaped arm extending from the rear wall of the housing, thereby releasing the front and rear bellows portions, along with the internal piston mechanism, to return to original position and force the medicament from the dosage cavity via a nozzle of the vial-dispenser.
Abstract:
The pump comprises a body with a forward end or nozzle with an outlet (11) covered by an elastic membrane (24), and connected to a duct with an inlet. The body of the pump contains a piston which traps and expels a predetermined volume of fluid on each stroke, while the outlet is in the form of an axial channel. At the end of each stroke the piston is returned to its original position by at least one elastic section (22,23) of the container, pleated in an accordion shape; the elastic membrane can also be made as part of the container, which can be made eg. from rubber or other elastomer material.
Abstract:
An aerosol tip mechanism for an aerosol-type dispenser for dispensing liquid content has a flexible outer shell, a rigid cap portion composed of lower and upper portions, and a rigid nozzle portion having a rigid shaft received within the outlet portion of the flexible outer shell. The rigid shaft interfaces the outlet portion of the outer shell, forming a first normally-closed one-way valve. The lower and upper portions of the rigid cap portion form boots adapted to receive an outlet portion of the flexible outer shell, the boots thereby constraining a lateral motion of the outlet portion of the outer shell, and symmetrically centering the outlet portion around the rigid shaft of the nozzle. The rigid nozzle portion includes a plurality of liquid channels for delivering liquid from a reservoir to a swirling chamber defined within the rigid cap portion, which liquid channels are configured to minimize energy losses of the liquid and promote a more homogeneous fluid particle size in the dispensed aerosol. The aerosol tip mechanism provides for long-term sterility of the stored fluid, which in turn allows for preservation of the sterility of non-chemically preserved formulations, which may be in the form of suspension or liquid gels.
Abstract:
A prosthesis for implanting in an eye has a lens member and a double interface member which is coupled to the periphery of the lens member. The double interface member is comprised of a more superficial branch and a deeper branch which project out from the lens member. The double interface member has a plurality of pores for permitting the ingrowth of tissue to anchor the prosthesis to the eye. The double interface member also has an anatomical structure into which eye tissue is inserted, so as to become an immediate anchor to the eye and an immediate barrier to external pathogens.
Abstract:
A mechanical lid or a plug (101) interacts with an opening (1036) of a pouch or a container (103), as well as with a rigid ring (102) placed inside the container (103) opening to provide a tight seal of the opening (1036). The mechanical plug (101) compresses both the outside of the opening (1036) and the inner face of the ring (102) placed inside the container opening (1036). The radial edge of the inner face of the mechanical plug (101) has an arch-shaped annular recess (101a) extending around the plug (101) such that the radial edge of the plug (101) is adapted to hug the perimeter of the container opening (1036). In addition, attached to the inner face of the mechanical plug (101) are two or more legs (1011) which extend perpendicular to the inner face of the mechanical plug (101) and engage the bottom of the rigid ring/radial groove combination. The outside surface of the neck region of the container opening (1036) and the interior surface of the annular recess of the mechanical plug (101) each has one or more protrusions (1013,1014,1015) which force the container material displaced by compression to be confined within a defined area, thereby ensuring the tightness of the seal for a prolonged period of time. The lower surface of the mechanical plug (101) is sloped downward in the direction of the centre, to which a plunger (1017) is attached for insertion into the liquid content of the container before the mechanical plug (101) is snapped into the container opening (1036), thereby substantially eliminating the residual air bubbles which may otherwise remain trapped between the surface of the liquid and the lower surface of the mechanical plug (101), which allows airless filling of the container without the need for a vacuum condition.
Abstract:
The disclosure relates to an apparatus (110) for applying medicament to an eye comprising an inner casing (112) and an outer casing (114) coupled to the inner casing and moveable relative thereto. An eyecup (120) is supported on one end of the inner casing. The eyecup defines a surface shaped to conformably engage the facial tissue surrounding an eye. An ocular vial (134) is supported within the inner casing. The ocular vial holds medicament for release into an eye. An eyelid displacing member (156) is coupled to the outer casing (114) and slideably mounted through the inner casing. The eyelid displacing member includes a depresser tab (158) adapted to engage the facial tissue below an eye. The depresser tab engages the facial tissue upon moving the outer casing toward the inner casing, thus displacing the lower eyelid to expose the ocular cul-de-sac. A dispensing member (148) is provided on the outer casing and is adapted to actuate the ocular vial (134) upon moving the outer casing toward the inner casing, to release medicament onto the expose ocular cul-de-sac of the eye.
