Abstract: An eye drop dispensing device includes a trough member with a space to receive a cartridge housing enclosing a collapsible bag containing an ophthalmic liquid and comprising a spring finger applying pressure to the bag. The bag includes a wall pierced by a needle coupling the liquid to pump means through a one-way valve. The pump means includes a plunger biased to a resting position establishing a dosage chamber. Actuator means moves the plunger to enlarge the dosage chamber, causing a drop in pressure which draws a predetermined quantity of the liquid through the one-way valve into the dosage chamber. The actuator means then releases the plunger so that it moves to compress the dosage chamber to pump the liquid in the dosage chamber through a second one-way valve to spray the liquid through pinholes formed in a nozzle angled to direct the liquid as eye drops to the user's eye.

Abstract: The suction tube set employs a compressed cellulosic sponge mass as a fluid absorber in the suction line for absorbing an amount of fluid, for example 1.5 cc, without any significant increase in resistance to air flow. The compressed sponge mass is secured in place within a tubular housing of the suction tube set with a gap formed between each end of the sponge mass and an end cap of the housing to avoid blockage of air flow.

Abstract: A portable eyeflushing device is disclosed having bladders which store an eyeflushing fluid. The bladders are attached to a mask that may be easily placed on a user so as to cover or enclose the user's eyes. A strap on the mask attaches the device to the user's head such that it is retained in position without the necessity of holding it in position. The bladders have tear strips on a portion extending internally of the mask which are connected to pull cords extending to the exterior of the mask and which may be manually grasped and pulled to tear the strips away from the bladder. This opens the bladders and allows the eyeflushing fluid to be dispensed from the bladders into the interior of the mask and into the user's eye. A nose piece on the interior of the mask prevents eyeflushing fluid on one side of the mask from passing to the other side of the mask and thereby prevents contamination of the user's other eye. A pair of digit covers extend outwardly from the sides of the mask.

Abstract: An eyecup (10) having a rim portion (14) that conforms to an orbit portion which surrounds an eye (12) on the face of a person is placed over the eye. The eyecup (10) forms a liquid confining chamber (45) adjacent the eye (12). The skin above and below the eye (20, 22) is drawn away from the eye (12), with the eyecup being pushed against the skin (20, 22) such that the rim portion (14) applies sufficient pressure against the skin for holding the eye (12) open. Eyewash is delivered and drained to and from the chamber (45) by inlets (50, 52) and an outlet (60). The inlets and the outlets are interchangeable. Eyewash delivered into the chamber (45) is directed such that the flow of the eyewash first contacts a surface of the eye (12) which is spaced a distance from the corneal portion (70) of the eye and then flows over and across the entire eye.

Abstract: A device for applying a liquid to an eye has a liquid accommodating chamber with an opening limited by an edge so that the user's eye can be placed into contact with the edge with an eye surface facing toward the interior of the chamber, and a liquid circulating unit which forcedly circulates the liquid in the chamber to move the liquid in a direction which is transverse to an axis of the opening and along the eye surface.

Abstract: A sealed, disposable pocket-size package for an eye-rinsing liquid comprises a flexible plastic bottle containing the liquid. The bottle includes a neck that is closed by a cap welded thereto. One end of the cap communicates with a connector for a liquid discharge tube that is located within the bottle, and the other end of the cap defines a liquid sprinkle member which extends into a cup-shaped eye bowl that is integral with the cap. The eye bowl is shaped to define an open mouth and includes a liquid drainage hole in a bottom wall of the bowl. The open mouth of the eye bowl is sealed closed by a cover that is tearably welded thereto, the cover including an integral plug which extends from the inner surface of the cover across the bowl into the drainage hole to also close the drainage hole.
