ABSTRACT:
A pill-crushing apparatus includes first and second arms having axially offset proximal and distal ends. The proximal end of the first arm is provided with a handle and a pair of apertures. The proximal end of the second arm has a handle and an opening. The arms are pivotally conjoined midway along respective longitudinal lengths thereof. The first arm has a male pill-crushing block provided with a dome-shaped bottom surface that is statically coupled to a distal end of the first arm. The second arm has a female pill-holding cup with an arcuate inner bottom surface that is anchored to a distal end of the second arm. The cup has a hollow semi-spherical shape and articulates about a fulcrum axis registered orthogonal to the longitudinal length of the second arm. A pill splitting mechanism includes shoulders formed with the first and second arms and protruding away therefrom.
