The present invention is directed to methods and apparatus for tempering the temperature of a liquid in a fluid conducting system. More particularly, the invention relates to tempering the temperature of water supplied to a fixture from a water heater in a fluid conducting system.

An emergency wash system is configured to dispense a fluid. The emergency wash system includes a basin, a sprayhead disposed at least partially over the basin, and a drain conduit coupled to the basin. The sprayhead includes a fluid inlet portion, a first fluid outlet portion coupled to the fluid inlet portion, and a second fluid inlet portion coupled to the fluid inlet portion. The fluid inlet portion is oriented substantially parallel to the drain conduit and vertically above the drain conduit.

A device (10) for removing debris from tissue around an eye is disclosed. The device (10) includes an eyecup (12a) having an opening (20a) and a cavity (18a), wherein the opening (20a) is of a size and shape sufficient to cover the eye. The device also includes an ultrasonic generator (60a) coupled to the eyecup (12a) and is configured to apply ultrasonic energy to a fluid in the eyecup (12a) to remove debris from the tissue. A method of removing debris from tissue around an eye a subject is also disclosed. The method includes covering the subjects eye with an eyecup (12a) having a cavity (18a) and filling the cavity (18a) of the eyecup (12a) with a fluid to bathe the eyelid margin with the fluid. Applying ultrasonic energy to the fluid at a frequency and for a duration sufficient to disrupt debris around the eye.

An apparatus to maintain an environment over an anterior surface of a patient eye can include an enclosure sized and shaped to be seated about the patient eye to form a cavity within the enclosure. The enclosure can be configured to contain a fluid other than ambient air in contact with the patient eye. The apparatus can include a fluid regulator in communication with the enclosure, where the fluid regulator can be configured to regulate the composition of the fluid contained within the enclosure.

A combination emergency wash and faucet unit includes a base, an emergency wash arm pivotally coupled to the base, and a spout pivotally coupled to the base. The emergency wash arm includes an emergency wash unit. The emergency wash arm is rotatable relative to the base about a first vertical axis between a stored position and an active position. The spout is rotatable relative to the base about a second vertical axis. The first vertical axis is substantially parallel to the second vertical axis and offset from the second vertical axis. Movement of the emergency wash arm causes a corresponding movement of the spout.
