Abstract: A pipette for delivering a measured volume of liquid having an elongated hollow tubular body (or capillary tube) (2) configured to draw liquid by capillary action, the hollow tubular body having a lower open end and an upper open end; and a chamber (3) structurally connected to the upper end of the tubular body (2), the chamber having an orifice (4) in the upper portion of the chamber.

Abstract: A bidirectional side-slit duckbill valve apparatus for use with catheters and similar devices. The apparatus can comprise a duckbill valve configured to allow fluid to flow through it only in a first direction and one or more side-slit valves configured to allow fluid to only flow through them in a second direction, opposite the first direction. In an embodiment, fluid can only flow through the duckbill valve if it is under a substantially positive pressure and can only flow through the side-slit valves if it is under a substantially negative pressure. In an embodiment, fluid that is not pressurized will not flow through either the duckbill valve or the side-slit valve. In an embodiment, the bidirectional side-slit duckbill valve apparatus can also comprise a funnel for directing a guidewire.

Abstract: A method of arresting blood flow from a bleeding wound including the steps of (1) providing a solid hemostatic tablet preferably including potassium ferrate and a cation ion exchange resin pressure formed into a tablet for delivery onto a bleeding wound, the tablet defining a proximal portion and a distal portion, (2) applying the proximal portion against the bleeding wound to improve the rate of adhesion to a bleeding wound surface, and then (3) applying pressure against the tablet over the wound site. After the seal is formed from the interaction of blood or exudates with the proximal portion of the tablet, the distal portion of the tablet delaminates from the proximal portion to form a reservoir to stop further bleeding and to provide antimicrobial protection and healing. The tablet may be applied to any surface orientation and take any shape and thickness possible.

Abstract: An injection device has a dispensing chamber housing, a plunger, and a temperature control device. The dispensing chamber housing has a first part and a second part. The first part is thermally coupled to a needle. The second part is thermally coupled to the first part. The second part has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. The plunger is engaged with an inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The temperature control device at least partially surrounds the dispensing chamber housing and is capable of altering a temperature of the substance in the dispensing chamber. The second part has a greater thermal coefficient than the first part.

Abstract: The present invention is directed to a pulsatile ophthalmic peri-corneal drug delivery device. The device includes an annular body and a mechanism for releasing multiple separate and distinct doses of a therapeutic composition over an extended period of time.

Abstract: The present invention provides a device to facilitate the self-administration of eye drops. The device includes a body portion adapted for placement on the user's face, generally over the eye in which the drops are to be applied. The body portion preferably includes an integral handle which may be held between the thumb and forefinger of the user. Many embodiments may also incorporate a nose bridge to assist in locating the device in the correct position.

Abstract: A dispensing tip apparatus for an eye drop dispenser to administer topical ophthalmic solutions is described. The apparatus integrates an ophthalmic solution-dispensing tip with an optical gauging assembly. The tip provides continuous visual feedback about it orientation and relationship to the eye. The dispensing tip when attached to any standard topical ophthalmic solution dispensing bottle or reservoir enables the user to view a target, visually align the dispenser tip, and administer an eye drop with precision. There is also a visual feedback by which the dispenser tip is prevented from gaining too close proximity and contacting the eye, thus preventing contamination of the medication and its dispenser. The visual feedback can also contain textual or graphic information that serves as a promotional advertisement.

Abstract: Apparatus for attaching to a squeeze bottle or other dispenser for delivering drops to an eye comprises an axial member and a laterally extending leg. The axial member is attached to the bottle and receives drops or liquid therefrom. The leg is rested against the patient's nose bridge so that it directs fluid to a trough and releases drops into the eye after a predetermined threshold volume is exceeded.

Abstract: An eyewash system is disclosed. The eyewash system includes a mounting apparatus and a container coupled to the mounting apparatus and having a removable portion. Movement of the container relative to the mounting apparatus separates the removable portion from the container to provide an opening in the container. The removable portion may be provided on a cap coupled to the container. The container may be coupled to the mounting apparatus by a retaining device (such as a pin) inserted through one or more members extending from the base and through a tab extending from the removable portion.

Abstract: A portable eye washer is described including a bladder, which may be disposable, filled with an eye-washing solution such as water or a solution specially-designed for cleaning eyes. The bladder may be made of rubber, a thin plastic, or other material so long as the bladder material is generally not permeable to the eye washing solution.

Abstract: An ophthalmic device is provided for administering fluid eye medication from a dispenser (5) to a human eye, said device comprising a housing (1) comprising a base portion (2) having a first opening (4), whereby the dispenser (5) is releasably engaged with the base portion (2) and the nozzle of the dispenser is assembled through the said first opening (4), and at least one positioning member (3) extending outwardly from the base portion (5) having an edge at the outer end to be placed against the head of a user adjacent to the eye to keep the said dispenser (5) at a predetermined distance from the eye, wherein said base portion (2) further comprises a second opening (8) providing a target for directing the eye upon administering the fluid eye medication to the eye, and in that said base portion (2) has, on its side directed towards the eye, an entirely or partially reflecting and/or colour-discriminating surface.

Abstract: An apparatus is used to apply medicament to an eye and stores the medicament in a medicament chamber. A nozzle is coupled in fluid communication with the medicament chamber and is formed by an outer nozzle portion and an inner nozzle portion received within the outer nozzle portion. A tight interface is defined between the inner nozzle portion and the outer nozzle portion and is normally in a closed position to prevent the passage of medicament through the nozzle. The interface opens in response to the flow of medicament of sufficient pressure into it to permit the passage of medicament through the nozzle for release into the eye.

Abstract: An improved miniscule fluid volume dispenser tip including a tube having an elongated constant diameter small bore disposed at the outlet end thereof with a fluid reservoir disposed at the opposite internal end thereof, the outlet end of the dispenser tip being sharply cut away to reduce surface area to which the dispensed liquid may be attach.
