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 pump-type dispenser for dispensing predetermined doses of medicament in droplets or in spray form to the nasal area incorporates a rigid vial for medicament, an expandable pouch located within the rigid vial, a nasal screen, a one-way actuation mechanism, a one-way valve mechanism in the nozzle area and a spring element, both the valve mechanism and the spring element being formed as integral portions of the pump body. The one-way valve mechanism in the nozzle area ensures a one-way movement of medicament from the dispenser, thereby preserving substantially perfect sterility of the medicament in the dispenser, without requiring the use of preservatives. The one-way actuation mechanism enables the user to load and dispense a uniform quantity of medicament with a uniform actuation force and speed via a single continuous motion of the actuation mechanism. The rigid vial/expandable-pouch combination facilitates improved long term use, as well as uniformity of dosage independent of the pump orientation.
Abstract:
An automated process for filling a sealed receptacle (1) with a fluid under aseptic conditions is disclosed. The sealed receptacle has at least one part (2B) made of a material capable of being pierced by a hollow needle (8R) and sufficiently flexible to close itself up again after removal of the hollow needle. In the automated process, the part (2B) of the sealed receptacle is pierced using a hollow filling needle (8R) which is in contact with the fluid to be channeled into the receptacle (1). During the process of filling the receptacle (1), the perforating end of the hollow filling needle (8R) is maintained under aseptic conditions by means of laminar gas flow.
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:
An ocular treatment apparatus for applying medicament into an eye has a vial defining a vial cavity for holding medicament. A nozzle is attached over an opening in the vial and is in fluid communication with the vial cavity for releasing drops of medicament. A piston member is suspended within the vial and slideably engaged within the vial cavity for displacing a substantially predetermined volume of medicament through the nozzle for release into the eye.
Abstract:
An apparatus for applying medicament to an eye has an inner casing and an outer casing coupled to the inner casing and moveable relative thereto. An eyecup 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 is supported within the inner casing. The ocular vial holds medicament for release into an eye. An eyelid displacing member is coupled to the outer casing and slideably mounted through the inner casing. The eyelid displacing member includes a depresser tab 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 is supported by the outer casing. The dispensing member is adapted to actuated the ocular vial upon moving the outer casing toward the inner casing, to release medicament onto the exposed ocular cul-de-sac of the eye.
