Pill crusher device and method

摘要

A pill crushing apparatus for use with first and second nestable cups includes a first stage of operation wherein a first cup holder is moved linearly toward a second cup mounting surface holding a second cup and a second stage of operation wherein the first cup holder rotates relative to the rotationally fixed second cup. During the first stage of operation, the pills first may begin to crush against the linear load being applied thereto, and thereafter grind into a fine powder due to the rotational force of the first cup against the second cup.

1. Pill crushing apparatus for use with first and second nestable cups, said apparatus comprising:
a) a first cup holder configured to removably hold said first cup; b) a cup holder fixture axially aligned with said first cup holder, said cup holder fixture including a first set of threads; c) a rotatable base part axially aligned with said cup holder fixture opposite said first cup holder, said rotatable base part including a second set of threads which mesh with said first set of threads on said cup holder fixture such that said cup holder fixture and said rotatable base part may translate linearly with respect to each other; d) a second cup mounting surface axially alignable with said first cup holder opposite said cup holder fixture and configured to releasably engage said second cup; and e) a brake releasably connected to said cup holder fixture, said brake operable between an engaged position wherein said cup holder fixture cannot rotate and is thereby forced to translate linearly along said rotatable base part when said rotatable base part is rotating, and a released position wherein said cup holder fixture may rotate with said rotatable base part; whereby, upon rotation of said rotatable base part and when said brake is in said engaged position, said cup holder fixture translates linearly along said rotatable base part toward said first cup holder moving said first cup holder into engagement with said second cup mounting surface and causing said brake to move to said released position and thereby allowing said cup holder fixture to rotate with respect to said second cup mounting surface and thereby imparting a grinding force against pills held between said first and second cups.
