摘要： A system (10) for measuring a diameter of a limbus of an eye (12). An image recorder (14) is at a known location apart from the eye and records an illuminated limbus image. An illumination source (16) at a known location relative to the image recorder (14) illuminates the limbus. A computer device (18) connected to the image recorder (14) determines the diameter of the limbus from the recorded illuminated limbus image.

摘要： An apparatus for analyzing a subject's cornea includes a frame having first and second ends, a single curvature (i.e. non-planar and non-axisymmetrical) screen associated with the first end of the frame, the non-planar and non-axisymmetrical screen having an opaque covering which is interrupted along its surface to form a pattern. A light source is disposed to cast the pattern placed on the screen onto the subject's cornea, thus causing a pattern to reflect therefrom. A light detector (e.g. a camera, CCD, or human eye) is disposed to sense the pattern reflected from the subject's cornea. The improved Placido plate is easier to manufacture. The design allows for incorporation of extremely complex pattern shapes, while its shape helps to maintain focus of the image.

摘要： A device that projects light rays and beams onto the eye in a predetermined pattern or arrangement of patterns, wherein the light rays or beams scatter in the eye tissues and which images of scatter are captured by video scanning cameras. The images are transferred into digital information for processing, storage, display or retrieval by a processing device which also determines the location, and position of the scattered light in space and prepares a mathematical representation of the light representing the shape, thickness, and relationship of the tissues of the eye.

摘要： A fluid conduit coupling assembly has a depressible latch mechanism that secures a first fluid conduit to a second fluid conduit via a first coupler and a second coupler. The first coupler connects to the first fluid conduit and the second coupler connects to the second fluid conduit. The depressible latch mechanism is formed by a pair of cantilevered buttons disposed in symmetrically opposed positions on one of the couplers. The cantilevered buttons have engagement lips that extend distally with catches that extend radially outward to engage a ridge formed on an interior wall of the opposing coupler. Fluid ports within the couplers interface when the couplers connect to provide fluid flow between the first and second conduits. Valves may be disposed in each of the couplers to arrest fluid flow when the couplers are detached and automatically open to allow fluid to flow when the couplers are connected.

摘要： The present invention is a fluid conduit coupling assembly for coupling a first fluid conduit to a second fluid conduit. The fluid conduit coupling assembly comprises a first coupler and a second coupler. The first coupler is for connecting to the first fluid conduit and comprises a first housing and a first valve. The first valve comprises a first lever arm. The second coupler is for connecting to the second fluid conduit and comprises a second housing and a second valve. The second valve comprises a second lever arm. When a force is applied to couple together the couplers, at least a portion of said force is communicated to each lever arm, thereby causing each valve to pivot from a closed position to an open position. The first valve and first lever arm are contained within the first housing, and the second valve and second lever arm are contained within the second housing.
