Abstract

A pharmaceutical waste system for treating a residual pharmaceutical composition disposed in a pharmaceutical dispenser includes an extraction stage, a pharmaceutical dispenser coupler, and a pharmaceutical waste treatment stage. The extraction stage is in fluid communication with the pharmaceutical dispenser and is configured to extract at least a portion of the residual pharmaceutical composition from the pharmaceutical dispenser. The pharmaceutical dispenser coupler is configured to couple the pharmaceutical dispenser to the extraction stage. The pharmaceutical waste treatment stage is in fluid communication with the extraction stage and is configured to change the residual pharmaceutical waste composition extracted from the pharmaceutical dispenser in one of a chemical and physical manner. The present disclosure also provides a method of disposing of a residual pharmaceutical composition from a pharmaceutical dispenser.

First claim

What is claimed is:

1. A pharmaceutical waste system for treating a residual pharmaceutical composition disposed in an IV bag, the pharmaceutical waste system comprising:
an extraction stage for being placed in fluid communication with the IV bag, with said extraction stage being configured to extract at least a portion of the residual pharmaceutical composition from the IV bag;
a pharmaceutical dispenser coupler configured to couple the IV bag to said extraction stage;
a pharmaceutical waste treatment stage in fluid communication with said extraction stage, said pharmaceutical waste treatment stage being configured to change the residual pharmaceutical composition extracted from the IV bag in one of a chemical and physical manner; and
a main housing, with said extraction stage and said pharmaceutical waste treatment stage at least partially disposed within said main housing.

2. The pharmaceutical waste system of claim 1 wherein said pharmaceutical waste treatment stage is further defined as a separation stage, said separation stage being configured to separate the residual pharmaceutical composition extracted from the IV bag into a purified waste portion and a contaminated waste portion.

3. The pharmaceutical waste system of claim 2 wherein said separation stage comprises a filter assembly comprising a filter housing and a filter media disposed within said filter housing.

4. The pharmaceutical waste system of claim 3 wherein said filter media is configured to bind with at least a portion of the residual pharmaceutical composition extracted from the IV bag such that said filter media retains said contaminated waste portion.

5. The pharmaceutical waste system of claim 3 wherein said filter media comprises activated charcoal.

6. The pharmaceutical waste system of claim 3 wherein said filter assembly comprises a replaceable cartridge removably coupled to said filter housing, with said filter media disposed within said replaceable cartridge.

7. The pharmaceutical waste system as set forth in claim 1 wherein said pharmaceutical waste treatment stage is further defined as a chemical treatment stage, with said chemical treatment stage being configured to treat the residual pharmaceutical composition extracted from the IV bag in a chemical manner.

8. The pharmaceutical waste system of claim 7 wherein said chemical treatment stage comprises a chemical treatment vessel in fluid communication with said extraction stage, and a chemical agent disposed within said chemical treatment vessel.

9. The pharmaceutical waste system of claim 8 wherein said chemical agent comprises a deactivator, a denaturant, an oxidizer, and combinations thereof.

10. The pharmaceutical waste system as set forth in claim 1 wherein said extraction stage comprises a pump in fluid communication with said pharmaceutical dispenser coupler.

11. The pharmaceutical waste system of claim 10 wherein the pharmaceutical dispenser coupler is further defined as a first pharmaceutical dispenser coupler configured to couple to a first IV bag, and with the pharmaceutical waste system further comprising a second pharmaceutical dispenser coupler configured to couple to a second IV bag, wherein said extraction stage comprises a manifold, said manifold comprising,
one or more manifold inlets configured to receive the residual pharmaceutical composition from the first and second IV bags, and
a manifold outlet configured to output the residual pharmaceutical composition received from the first and second IV bags to said pump.

12. The pharmaceutical waste system of claim 1 wherein said main housing further comprises a security mechanism configured to prevent unauthorized access to said extraction stage and said pharmaceutical waste treatment stage.

13. The pharmaceutical waste system as set forth in claim 1 wherein said extraction stage comprises a reservoir in fluid communication with said pharmaceutical waste treatment stage, with said reservoir upstream of said pharmaceutical waste treatment stage for temporarily storing the residual pharmaceutical composition extracted from the IV bag.

14. The pharmaceutical waste system of claim 1 further comprising a waste analysis stage in fluid communication with one of the extraction stage and the pharmaceutical waste treatment stage, with the waste analysis stage being configured to analyze an output or an input of one of the extraction stage and the pharmaceutical waste treatment stage.
