Abstract

A method and apparatus for assembling a plurality of independently formed solid components is provided thereby forming a single delivery vehicle for a pharmaceutical or pharmaceutical-like product. The solid components can be held and fed to the apparatus via a plurality of magazines. Pusher rods and the like can be used for positioning each of the solid components. Where the components are connected via a bonding liquid, a sprayer is provided and compression pins or the like press the components with the bonding liquid together to form the final product. A rivet or other connection structure can also be used and driven through holes in each of the solid components to form the final product.

Claims

1. An apparatus for assembling a pharmaceutical product having at least three independently formed solid tablets, the apparatus comprising:

at least three component magazines, each holding at least one of said solid tablets;

a pusher assembly in communication with said at least three component magazines, wherein said pusher assembly comprises a single reciprocating pusher that retracts to release the solid tablets from all of said component magazines, and wherein said single reciprocating pusher positions all of the solid tablets that are dispensed from said at least three component magazines; and

a connector assembly in communication with the pusher assembly for connecting the solid tablets from each of said at least three component magazines together, to form the pharmaceutical product.

2. The apparatus of claim 1, wherein the apparatus comprises only three component magazines.

3. The apparatus of claim 2, wherein the connector assembly comprises:

a sprayer that applies a bonding liquid to at least one of the solid tablets that are dispensed from each of said component magazines and one or more compression pins for pressing the solid tablets together.

4. The apparatus of claim 3, wherein said bonding liquid is selected from the group consisting of water, alcohol, polyethylene glycol, glycerine, polyethylene oxide polymers, methylcellulose, methylcellulose derivatives, hydroxypropylmethylcellulose, hydroxyethylcellulose, ethylcellulose, or any combinations or mixtures thereof.

5. The apparatus of claim 2, wherein the connector assembly comprises:

a rivet dispenser and a rivet driver in communication with said rivet dispenser, wherein said rivet driver positions a rivet in a hole in each of the solid tablets that are dispensed from each of said component magazines to provide a mechanical connection for the solid tablets.

6. The apparatus of claim 3, wherein said sprayer comprises a solenoid pump that is operably connected to a supply of said bonding liquid, wherein said solenoid pump is actuatable to draw bonding liquid from said bonding liquid supply, and to pass it to a dispenser for application to at least one solid component.

7. The apparatus of claim 2, wherein said connector assembly comprises:

a confining bracket for receiving and confining the solid tablets in an aligned orientation, and

at least two opposed compression pins, each of the at least two compression pins to apply pressure to an opposed end of the aligned solid tablets.

8. The apparatus of claim 3, further comprising:

a microprocessor;

at least one data collection device; and

an interface, wherein said microprocessor and said data collection device are in electronic communication with said interface.

9. The apparatus of claim 8, wherein said data collection device comprises a radio frequency identification (RFID) system and a bar code reader, wherein said RFID system and said bar code reader system are each independently in electronic communication with said interface.

10. The apparatus of claim 9, wherein said component magazines have RFID tags disposed thereon, said tags containing information about the solid tablets disposed within said component magazines, wherein said RFID system comprises an antenna, a module, and an interface, which are all in electronic communication with each other, and with said interface, and wherein said antenna reads said information from said RFID tags and communicates said information to said interface.

11. The apparatus of claim 10, wherein said bar code reader is in electronic communication with said interface, and wherein said bar code reader reads a bar code from a collection device placed in the front of said apparatus to collect said pharmaceutical product, and communicates said bar code to said interface.

12. The apparatus of claim 11, wherein said interface comprises a software program embedded therein, whereby said software program compares the information communicated from said bar code reader and said RFID system, to ensure that said component magazines are correct for placement within said apparatus.

13. The apparatus of claim 1, wherein said solid tablets are selected from the group consisting of circular and elliptical tablets.

14. An apparatus for assembling a pharmaceutical product having at least three independently formed solid tablets, the apparatus comprising:

at least three component magazines each holding at least one of said solid tablets;

a track assembly in communication with said at least three component magazines for positioning the plurality of said tablets that are dispensed from said at least three component magazines; and

a connector assembly in communication with the track assembly for connecting one of the plurality of said tablets from each of said at least three component magazines together, to form the pharmaceutical product,

wherein said track assembly comprises a rotating track, a rotating post, and a piston assembly, all operably connected to each other, so that upon rotation of said rotating track, said rotating post removes one of said solid tablets from each of said component magazines, so that the solid tablets are on said piston assembly.

15. The apparatus of claim 14, wherein the apparatus comprises only three component magazines.

16. The apparatus of claim 15, further comprising a pipette assembly that applies a bonding liquid to at least one of the plurality of said solid tablets.

17. The apparatus of claim 14, wherein said track assembly further comprises a cam track that is operably connected to said piston assembly, so that upon rotation of said rotating track, said cam track alternatively lowers and raises said piston assembly.

18. The apparatus of claim 17, wherein said track assembly further comprises a pipette cam track that is operably connected to said pipette assembly, so that upon rotation of said rotating track, said pipette cam track alternatively lowers and raises said pipette assembly.

19. The apparatus of claim 18, wherein said connector assembly comprises a pusher blade that is operably connected to said cam track and said piston assembly, so that the pharmaceutical product is compressed under said pusher blade by said piston assembly after the plurality of said solid tablets have been collected from said component magazines.

20. The apparatus of claim 15, further comprising a user interface that is operably connected to said at least three magazines, said track assembly, and said connector assembly, so that said user interface sets the number of said pharmaceutical tablets to be assembled.
