ABSTRACT:
A device including an eye cup portion affixed to one end of an extendible tube portion, the other end of the tube portion is adapted for releasably attaching the tube portion to the nozzle of a spray-mist fluid dispenser. In combination, the device and mist dispenser are operable for controlling the delivery of a fluid to the eye. The device functions both as mask to confine the distribution of the spray mist ejected from the nozzle upon the eye and as a jig operable for adjusting the distance between the mist dispenser nozzle and the eye cup portion of the device. In operation, with the device affixed to a spray mist dispenser nozzle and the tube portion unextended (nozzle closest to the eye), a dense mist is delivered to the cornea and surrounding eye tissues when mist is dispensed. When the tube portion is extended, the spray mist dispenser nozzle is further from the eye cup thereby reducing the density of the spray mist impinging on the eye. The tube portion of the device includes inner and outer concentric tubes and a conical containment chamber affixed to the outer tube and disposed within the eye cup portion of the device. The distance between the wide end of the eye cup and the nozzle engaging end of the tube portion is telescopically adjustable. The containment chamber may be removed from the device to permit the spray nozzle to be positioned nearer the eye. When the tube portion is unextended, the fluid spray mist impinges on the anterior surface of the eye with the greatest force and concentration. For a gentler, finer delivery of spray mist, the containment chamber is preferrably employed and the distance between the dispenser's nozzle delivery orifice and the eye cup portion adjusted and set for comfort and accurate dosimetry.
