US Patent 11672736 Pill cutter and method for using thereof

A pill cutter and a method for using thereof are provided. The pill cutter includes: a bottom case; a pressing plate provided with a blade and a shield plate provided with a slit. When the pressing plate rotates relative to the bottom case, the blade at least has a protected state and a pill-cutting state, in the protected state, the blade is positioned between the shield plate and the pressing plate after the two plates are separated from each other, and in the pill-cutting state, the blade passes through the slit and reaches the bottom case. The blade can be shielded automatically when the pill cutter is opened for putting the pill in, and safety of using the pill cutter is largely enhanced.
