Pill crusher with pill holder verification and safety features
A pill crusher device and method including a base and a lid movable between open and closed positions with respect to the base. The base includes a pill cup holder for holding a cup with one or more pills therein. The cup may include a flange that is keyed to the cup holder to prevent the cup from rotating with the cup holder. A head protrudes from the inside surface of the lid and is shaped to nest within the cup either directly against the pills, or against a second cup placed in the first cup with the pills located between the two cups.
1. A pill crusher, comprising:
a. a housing including a base and a lid which may be selectively moved between open and closed positions with respect to said base, said base including a cup holder shaped to receive a first cup therein, said lid including an element for breaking one or more pills placed in said first cup when said lid is in the closed position with respect to said base, said pill breaking element comprising a head shaped to be inserted into a second cup nested in said first cup, said head and said base exerting opposing forces upon said nested cups and one or more pills placed therebetween, said holder rotatably connected to said base and operable to rotate said first cup located therein with respect to said second cup which remains rotatably fixed; and
b. a verification system having a detectable element connected to said first cup and a detector connected to said housing, said verification system operable to verify said first cup is authorized for use with said pill crusher.
2. The pill crusher of claim 1 wherein at least one of said cups includes a textured surface for contact with a pill located between said nested cups.
3. The pill crusher of claims 2 wherein said textured surface is located on the outside bottom surface of said first cup.
4. The pill crusher of claim 2 wherein said textured surface is located on the outside bottom surface of said second cup.
5. The pill crusher of claim 1 wherein said holder includes a textured surface to increase frictional contact with said first cup such that said first cup will resist rotating independently of said cup holder.
6. The pill crusher of claim 1 wherein the head includes a textured surface to increase frictional contact with said second cup such that said second cup will resist rotating with said first cup.
7. The pill crusher of claim 1 wherein said holder and said first cup each include cooperating interlocking features ensuring said first cup will rotate together with said base.
8. The pill crusher of claim 7 wherein said interlocking features include a non-circular flange on said first cup and a cooperatively shaped recess on said base into which said flange may be removably secured.
9. The pill crusher of claim 8 wherein said flange is multi-sided.
10. The pill crusher of claim 9 wherein said flange is hexagonal.
11. The pill crusher of claim 7 wherein said interlocking features include a flange on said first cup, said flange having one or more holes formed therethrough which may align with and removably engage a respective protrusion on said base.
12. The pill crusher of claim 1 where said detectable element is a luminous phosphorous material.
13. The pill crusher of claim 1 wherein said detectable element is an RF tag.
14. The pill crusher of claim 1 where said detectable element is a bar code.
15. The pill crusher of claim 1 wherein said detectable element is a metallic material.
16. The pill crusher of claim 1 wherein said detectable element is a ferrous oxide material.
