ABSTRACT:
A combination scalpel blade removal and storage apparatus having an easy to grip hourglass-shaped, disposable plastic housing which includes a strategically located safety shield that prevents accidental cuts during the blade insertion and removal process. The housing is provided with an internal, blade receiving channel which closely receives the blade and positively locates the tang portion of the handle within the housing. The blade stripping mechanism of the apparatus comprises an integrally formed, spring loaded lever arm disposed externally of the housing. Pressing the lever effortlessly deflects the heel of the blade away from the tang and over into a recessed stop, or pocket formed near the forward portion of the housing. Retraction of the handle with a straight line, continuous movement, while maintaining an inwardly directed force on the lever, smoothly strips the blade from the handle.
