Abstract

A manually operable pill crusher device for use with pill pouches. A base includes a crushing surface over which a head is mounted. A handle is attached to a cam inside the head, and the head has a slot that permits the handle to move from a horizontal position to a vertical position. The cam is mounted inside a ram which slideably moves axially inside the head from a raised position in the head when the handle is vertical to a lowered position when the handle is horizontal. The ram includes a crushing surface engaging surface. The head also includes a slot through which a pill in a pouch can be inserted on to the crushing surface when the handle is raised. Lowering the handle then crushes the pill with axial force directly over the crushing surface, avoiding any cocking or arcuate pressure on the pill.

Claims (26)

1. A manually operable pill crusher device for use with pill pouches, comprising:

a base having a predetermined length and includes a sliding surface;

a head is mounted on said base and having a portion facing said sliding surface, said head having an arcuate slot extending from vertically over said sliding surface to perpendicular to said sliding surface;

a pouch slot in said head sized and positioned to permit insertion of a pill pouch therein;

a ram mounted inside said head and having a crushing surface for engaging said pouch slot; and

a cam mounted inside said head and attached to said ram;

a handle attached through said slot to said cam at one end and adapted to move in said slot between a horizontal position and a vertical position to cause said cam to thereby axially move said ram between a pouch insertion position and a pouch engaging position.

2. The device of claim 1 , wherein said handle further includes a grip portion on the end opposite the cam engaging end.

3. The device of claim 2 , wherein said grip portion includes an enlarged portion on its end opposite its end on said cam.

4. The device of claim 1 , wherein at least one of said crushing surface and pouch slot engaging said crushing surface includes a textured surface.

5. The device of claim 4 , wherein both of said surfaces are textured.

6. The device of claim 1 , wherein said pouch slot is positioned to permit access to either hand of a user of said device.

7. The device of claim 1 , wherein said slot in said head extends horizontally out from said cam and is sized to prevent movement of said handle when force is applied to said handle from either side thereof.

8. The device of claim 1 , wherein said handle extends substantially the length of said base.

9. The device of claim 1 , wherein said base further includes a stop facing said handle for supporting said handle in a horizontal position.

10. The device of claim 1 , wherein said cam is a cylinder with an offset pin mounting said cam to said handle.

11. A manually operable pill crusher device for use with pill pouches, comprising:

a base having a predetermined length and includes a sliding surface;

a head is mounted on said base and having a portion facing said sliding surface, said head having an arcuate slot extending from vertically over said sliding surface to perpendicular to said sliding surface;

a pouch slot in said head sized and positioned to permit insertion of a pill pouch therein by either hand of a user of said device;

a ram mounted inside said head and having a textured surface for engaging said pouch slot; and

a cam mounted inside said head and attached to said ram;

a handle attached through said slot to said cam at one end and adapted to move in said slot between a horizontal position and a vertical position to cause said cam to thereby axially move said ram between a pouch insertion position and pouch engaging position, said handle further including a grip portion on the end opposite the cam engaging end.

12. The device of claim 11 , wherein said slot in said head extends horizontally out from said cam and is sized to prevent movement of said handle when force is applied to said handle from either side thereof.

13. The device of claim 11 , wherein said base further includes a stop facing said handle for supporting said handle in a horizontal position.

14. The device of claim 11 , wherein said cam is cylinder with an offset pin mounting said cam to said handle.
