Abstract
A scalpel blade extractor and disposal unit formed of semi-flexible plastic material. The unit has a substantially closed chamber within which a blade mounted on a handle is received. The chamber has a top and a bottom and an abutment shoulder is attached to the top and extends below the plane of the bottom for the purpose of retaining the blade in the chamber. A mechanism is provided for increasing the distance between the top and the bottom so that the blade on the handle passes under the abutment shoulder. The bottom has a groove and shoulders around the groove for prying the heel of the blade up such that it is stopped by the abutment shoulder when the handle is withdrawn leaving the blade behind in the chamber.
