Abstract

A capsule shredding device is provided, which includes first and second housing sections. The first housing section has a chamber slightly larger than the capsule located in one end of the housing section so that when the capsule is seated in the chamber it cannot freely rotate in the chamber. A vial is releasably coupled to other end of the first housing section. One or more passageways extend from the bottom of the chamber toward the other end of the second housing section. The second housing section has an internal chamber with a spike extending into the chamber integrally formed on the interior upper section of the housing section. When the two housing sections are threaded together such that are drawn towards each other, the spike pierces the capsule, and upon further rotation the spike shreds the capsule thereby releasing the powder contained therein which flows through the one or more passageways into interior of the vial. Gaskets between the first and second housing sections and between the second housing section and the vial prevent powder or liquid in the vial escaping.

First claim

Therefore what is claimed is:

1. A capsule shredding device for shredding capsules containing powder medicament, comprising:
a first housing section having a first chamber formed in a first end of said first housing section for holding a capsule, said first housing section having an open second end, including at least one passageway through a bottom of said first chamber to a second chamber which extends to said open second end, a vial removably coupled to the open second end of said first housing section;
a second housing section having an open end and a closed end and having a second housing chamber formed therein, the closed end having a shredding spike formed thereon and extending from said closed end on an interior of the second housing section into said second housing chamber, said shredding spike having a pyramidal shape having four triangular shaped flat surfaces, at least one of said four triangular shaped flat surfaces including spike extending therefrom; and
said first and second housing sections having cooperating coupling mechanisms for coupling the open end of the second housing to the first end of said first housing section such that the shredding spike makes contact with a capsule in said first housing chamber, said cooperating coupling mechanisms configured to allow telescoping rotational movement of the first housing section with respect to said second housing section so said shredding spike rotates with respect to the capsule thereby shredding it causing the powder medicament to flow through said at least one passageway into said vial.

2. The capsule shredding device according to claim 1 , wherein said first and second housing sections are cylindrically shaped, and wherein said first end of said first housing has external threading around an outer periphery of said first end, and wherein the cylindrically shaped second housing includes internal threading on an interior wall of said second housing section enclosing said second chamber such that the first housing can be threaded into the open second end of the second housing section such that said first and second housing sections can be rotated with respect to each other thereby causing the shredding spike to penetrate into the capsule during rotation of the first housing section with respect to the second housing section.

3. The capsule shredding device according to claim 2 , wherein said shredding spike is a pyramidal shaped shredding spike having four triangular shaped flat surfaces, at least one of said four triangular shaped flat surfaces including spike extending therefrom.

4. The capsule shredding device according to claim 3 , wherein each of said four triangular shaped flat surfaces includes a spike extending therefrom.

5. The capsule shredding device according to claim 2 , wherein said first chamber has a shape and size to receive the capsule therein such that the capsule is held in a fixed position with respect to the first housing section and cannot rotate freely within said first chamber.

6. The capsule shredding device according to claim 2 wherein said capsule holding section has a capsule holding cavity sized for a capsule to be placed in said capsule holding cavity.

7. The capsule shredding device according to claim 1 , wherein each of said four triangular shaped flat surfaces includes a spike extending therefrom.

8. The capsule shredding device of claim 1 , wherein said first chamber has a shape and size to receive the capsule therein such that the capsule is held in a fixed position with respect to the first housing section and cannot rotate freely within said first chamber.

9. The capsule shredding device of claim 1 wherein said capsule holding section has a capsule holding cavity sized for a capsule to be placed in said capsule holding cavity.

10. The capsule shredding device of claim 9 wherein said first chamber is sufficiently deep such that the capsule is entirely contained within the first chamber such that it does not protrude out of the first chamber.

11. The capsule shredding device of claim 1 including a gasket disposed between said first and second housing sections to provide a seal when the first and second housing sections are coupled together and the capsule is being shredded to prevent any escape of the powder medicament from the first chamber.

12. The capsule shredding device of claim 1 wherein said first and second housing sections include textured outer surfaces for improved gripping of said first and second housing sections during rotation of one with respect to the other.

13. The capsule shredding device of claim 1 wherein one or both of said first and second housing sections include exterior grip features.

14. The capsule shredding device of claim 13 wherein said grip features are recesses or ridges.

15. The capsule shredding device of claim 1 wherein said vial removably coupled to the open second end of said first housing section is threaded, and an interior wall of said first housing has a complimentary thread such that said vial can be threaded into said open second end of said first housing section.

16. The capsule shredding device of claim 1 including a gasket disposed between said first housing section and said vial to provide a liquid tight seal between said first housing section and said vial when the first housing section and said vial are coupled together and the capsule is being shredded to prevent any escape of the powder medicament or liquid from said vial.

17. The capsule shredding device of claim 1 wherein said capsule shredding device is configured to be operated by hand.

18. The capsule shredding device of claim 1 including an extraction cap attachment port attached to said second housing section to which an extraction cap can be attached, and including at least one extraction channel between said second housing section and said extraction cap attachment port.

19. The capsule shredding device of claim 1 including capsule holding span members in said at least one passageway of said first housing section such that said capsule holding span members prevent a capsule from exiting said first chamber through said at least one passageway.

20. A capsule shredding device for shredding capsules containing powder medicament, comprising:
a first housing section having a first chamber formed in a first end of said first housing section for holding a capsule, said first housing section having an open second end, including at least one passageway through a bottom of said first chamber to a second chamber which extends to said open second end, a vial removably coupled to the open second end of said first housing section, said first chamber having a shape and size to receive the capsule therein such that the capsule is held in a fixed position with respect to the first housing section and cannot rotate freely within said first chamber;
a second housing section having an open end and a closed end and having a second housing chamber formed therein, the closed end having a shredding spike formed thereon and extending from said closed end on an interior of the second housing section into said second housing chamber; and
said first and second housing sections having cooperating coupling mechanisms for coupling the open end of the second housing to the first end of said first housing section such that the shredding spike makes contact with a capsule in said first housing chamber, said cooperating coupling mechanisms configured to allow telescoping rotational movement of the first housing section with respect to said secon
