摘要： An apparatus for managing and controlling fluid flow through a plurality of fluid conduits includes a chassis, a plurality of conduit occluders mounted in the chassis, each occluder for association with at least one of the plurality of fluid conduits and each being selectively actuatable between an open position permitting fluid flow through a respective fluid conduit and a closed position obstructing conduit fluid flow. A single actuator is mounted in the chassis, the actuator for adjusting the plurality of occluders between the open and closed positions. A roller cage is also mounted in the chassis for mechanically interconnecting the actuator to the plurality of conduit occluders so that the single actuator is mechanically capable of maintaining one of the plurality occluders in the closed position while maintaining another of the plurality of occluders in the open position.

摘要： A syringe-like device having a chamber in which a pressurizing piston reciprocates. The chamber is connected on one end to a vial containing a drug to be delivered to an eye and on the other end to a needle or cannula for administering the drug to an eye. Pulling proximally backwards on the piston creates a vacuum in the chamber and draws the drug out of the vial. Upon release of the piston, a spring pushes the piston forward, pressurizing the chamber. Delivery of the drug is controlled by a roller pinching off a section of compliant tubing between the chamber and the cannula, with a design similar to a peristaltic pump. A one-way valve prevents the drug from being expelled back into the vial. The flow rate of the drug out of the cannula can be controlled by rotation of the roller.

摘要： A system, apparatus and method for spatially distributed, spectrally neutral optical attenuation. One embodiment of the apparatus can include: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a motor for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame. The embodiments of the attenuator of this invention can be configured for use within an ophthalmic high brightness illumination system.

摘要： A system, apparatus and method for spatially distributed, spectrally neutral optical attenuation are disclosed. One embodiment of the apparatus comprises: an attenuator fin plate; a set of attenuator fins, wherein each of the fins is operably coupled to the fin plate at a preset fin angle to the fin plate normal such that the attenuator fins maintain their position relative to the fin plate as the fin plate moves; and a means for rotating the fin plate a set angular distance around an axis of rotation, wherein the axis of rotation is at a preset fin plate angle to a light beam direction of travel and wherein the attenuator fins block varying amounts of the light beam as the fin plate is rotated through the set angular distance. The attenuator fin plate and attenuator fins can be a single, integral component, wherein the attenuator fin plate is etched and stamped to form the attenuator fins, or separately formed components that are attached, for example, to a separate frame. The means for rotating the fin plate would then comprise means to rotate the attenuator frame. Means for rotating the attenuator fin plate or frame can include a stepper motor, for discrete step positions, or a continuously variable motor for infinitely variable positioning. The means for rotating the attenuator fin plate or frame can be electronically controlled, for example, by a microprocessor on a printed circuit board or other such controller as known to those having skill in the art. The preset fin angle can be 31 degrees, and the preset fin plate angle can be 90 degrees. Each of the attenuator fins can be operably coupled to the fin plate at the same preset fin angle and the fin plate and/or frame centered on the axis of rotation. Each fin's major axis can be parallel to every other fin's major axis, and the axis of rotation can be parallel to each fin's major axis. The set of attenuator fins can comprise eight attenuator fins and the attenuator fins can be spaced equally apart from one another. The attenuator fin plate and set of attenuator fins can be sized so as to interfere with the entire light beam cross-section/aperture at a position along the set angular distance corresponding to zero percent of the optical beam passing through the attenuator fins. The embodiments of the attenuator of this invention can be configured for use within an ophthalmic high brightness illumination system.

摘要： A centrifuge is provided with a mounting arrangement that secures a centrifuge bowl to a turntable in response to centrifugal force generated when the turntable is rotated. The centrifuge includes first and second retainers, one of which is connected to the turntable, while the other is connected to the centrifuge bowl. The second retainer engages the first retainer when the first and second retainers are in an interlocking position to secure the centrifuge bowl to the turntable. A movable arm is provided on the turntable and coupled to the second retainer, the movable arm has a ballast that forces the movable arm and second retainer in a first direction in response to centrifugal force generated by rotating the turntable so that the second retainer is forced into the interlocking position with the first retainer. In one embodiment, a vacuum applied to an opening in the turntable assists in mounting a centrifuge bowl to the turntable.
