Abstract

A pharmaceutical waste disposal assembly includes a fluid receiver body for receiving fluid pharmaceutical waste, said fluid receiver body may comprise a material that is clear, opaque, or otherwise see-through and having a capacity. The assembly also includes a first reaction agent positioned within the fluid receiver body, the fluid pharmaceutical waste contacting the first reaction agent to change the fluid pharmaceutical waste in one of a chemical and physical manner so that the fluid pharmaceutical waste is rendered unrecoverable. The assembly also includes a fluid absorber positioned within said fluid receiver body, said fluid absorber configured to absorb and retain fluid pharmaceutical waste deposited in said fluid receiver body. The assembly also includes a moisture-sensitive visual indicator that changes color when fluid pharmaceutical waste deposited in said fluid receiver body has reached a predetermined percentage of said capacity of said fluid receiver body.

First claim

What is claimed is:

1. A pharmaceutical waste disposal assembly, said pharmaceutical waste disposal assembly comprising:
a fluid receiver body for receiving fluid pharmaceutical waste, said fluid receiver body having a capacity;
a first reaction agent positioned within the fluid receiver body, the fluid pharmaceutical waste contacting the first reaction agent to change the fluid pharmaceutical waste in one of a chemical and physical manner so that the fluid pharmaceutical waste is rendered unrecoverable;
a fluid absorber positioned within said fluid receiver body, said fluid absorber configured to absorb and retain fluid pharmaceutical waste deposited in said fluid receiver body; and
a moisture sensitive visual indicator that changes color when fluid pharmaceutical waste deposited in said fluid receiver body has reached a predetermined percentage of said capacity of said fluid receiver body.

2. The pharmaceutical waste disposal assembly of claim 1 , wherein said fluid receiver body comprises a clear, opaque, or otherwise see-through material.

3. The pharmaceutical waste disposal assembly of claim 1 , further comprising a cap shaped for releasable attachment to said fluid receiver body that can be attached to said fluid receiver body prior to disposal.

4. The pharmaceutical waste disposal assembly of claim 1 , wherein said moisture sensitive visual indicator changes from first color to a second color.

5. The pharmaceutical waste disposal assembly of claim 4 , wherein said first color is white and said second color is red.

6. The pharmaceutical waste disposal assembly of claim 1 , wherein said moisture sensitive visual indicator is a fluid waste receiver sensor.

7. The pharmaceutical waste disposal assembly of claim 1 , wherein
said moisture sensitive visual indicator is positioned within said fluid receiver body.

8. The pharmaceutical waste disposal assembly of claim 1 further comprising a controller configured to receive input from the moisture sensitive visual indicator which alerts a user that a useful life of said disposal assembly has either expired, or that expiration is scheduled to occur in a predetermined time period.

9. The pharmaceutical waste disposal assembly of claim 8 further comprising a timer included as part of the controller or separate from the controller.

10. The pharmaceutical waste disposal assembly of claim 1 further comprising a solid receiver body for receiving solid pharmaceutical waste.

11. The pharmaceutical waste disposal assembly of claim 1 further comprising a receiver retainer that retains said fluid receiver body and/or a solid receiver body, with said receiver retainer comprising a locking mechanism for selectively inhibiting removal of said fluid receiver body and/or said solid receiver body from said receiver retainer.

12. The pharmaceutical waste disposal assembly of claim 1 further comprising a receiver retainer substantially enclosing said fluid receiver body and including one or more viewing windows to allow a user to view pharmaceutical waste deposited in said fluid receiver body.

13. The pharmaceutical waste disposal assembly of claim 1 , wherein the first reaction agent includes one or more of a denaturant, an emetic, and a bittering agent.

14. The pharmaceutical waste disposal assembly of claim 1 , wherein the first reaction agent includes an oxidizing agent.

15. The pharmaceutical waste disposal assembly of claim 1 , wherein the first reaction agent includes chlorine.

16. The pharmaceutical waste disposal assembly of claim 1 , wherein the first reaction agent is contained within a dissolvable packet.

17. A method of disposing pharmaceutical waste in a waste disposal assembly comprising a fluid receiver body and having a capacity, a first reaction agent positioned within the fluid receiver body, a fluid absorber positioned within said fluid receiver body, a moisture sensitive visual indicator positioned within said fluid receiver body, and a receiver retainer that retains said fluid receiver body, said method comprising the steps of:
uncapping and securing said fluid receiver body in receiver retainer;
observing a color change of said moisture sensitive visual indicator when fluid pharmaceutical waste deposited in said fluid receiver body has reached a predetermined percentage of said capacity of said fluid receiver body;
removing the fluid receiver body from the receiver retainer; and
disposing the fluid receiver body.

18. The method of claim 17 further comprising the step of wherein the fluid receiver body comprises a clear, opaque, or otherwise see-through material and the step of observing a color change is further defined as observing a color change through said material.

19. The method of claim 17 wherein the step of observing a color change is further defined as observing a color change of said moisture sensitive visual indicator from a white color to a red color.

20. The method of claim 17 further comprising the step of activating an additional waste receiver indicator which alerts a user that a useful life of said disposal assembly has either expired, or that expiration is scheduled to occur in a predetermined time period.

21. The method of claim 17 further comprising the step of capping the receiver body with its cover to seal the fluid pharmaceutical waste within the fluid receiver body.

22. The method as set forth in claim 17 , further comprising the step of locking the fluid receiver body to the receiver retainer.
