A device for administering a fluid includes a housing that holds a sterilization cassette having a shell, a fluid chamber, and a light transmitting window. An input directs fluid into the chamber. A light source is positioned to direct ultraviolet or other light through the window into the fluid chamber at an intensity sufficient to kill or render non-reproducible at least one species of a microorganism in the fluid while the fluid is in the chamber. An outlet receives fluid from the cassette and directs the fluid to a destination. The fluid is substantially uniformly exposed to the light while in the chamber. The cassette and light source are contained in a housing that prevents light from escaping the housing.

An ergonomic keyboard as shown in FIG.A for use with a stationary palm wherein the keys () of the keyboard are actuated only by motion of the joints in the digits. The keyboard may have a thumb region (), a palm rest region () and a hypothenar rest region which are discrete parts and are adjustable relative to one another along a longitudinal axis. Some keys may be actuated by the back surface of the digits. The keyboard may be on an upper portion () which is mounted on a base () such that three dimensional rotational adjustment is possible between the upper portion and base. The position of the keyboard relative to a user may be adjusted. The spacing of the keys on the keyboard may be spaced at different intervals and have different forces for actuation.
