ABSTRACT:
A sterile intravenous flow valve includes in-line valve mechanism which is maintained sterile in all of its positions. The valve also includes an adjustment member and a locking mechanism for selectively locking the adjustment member in place to thereby assure accurate flow rate settings. Sterility is achieved by providing a sealed chamber formed by a snap-fit engagement between the adjustment member and the main body member of the valve.
