Abstract

A system, device, and method for mixing a substance with a liquid pumps the liquid into a container of the substance to produce a solution. The container may be part of a container assembly including a port assembly for coupling with the container to produce an inlet and/or and outlet port for the container. The container assembly may be received within a receiving chamber for causing the coupling. The solution may be permitted to flow out of the outlet port when the solution rises within the container to a level of the outlet port so that the substance is partially diluted before flowing out of the outlet port.

Claims

1. A system for mixing a caustic substance with a liquid, the system comprising:

a primary container for containing the caustic substance, the primary container having a bottom and a top, the caustic substance filling the primary container from the bottom to a given point between the bottom and top, the primary container having an outlet between the given point and the top of the primary container;

a liquid controller operatively coupled with the primary container, the liquid controller being capable of adding a predetermined amount of the liquid to the primary container to produce a combined caustic substance and liquid, the liquid controller being capable of causing the combined caustic substance;

and liquid to rise to the outlet after the liquid is added, at least a portion of the combined caustic substance and liquid flowing from the primary container through the outlet after the combined caustic substance and liquid rises to the outlet.

2. The system as defined by claim 1 further comprising a final container capable of coupling with the outlet, the portion of the combined caustic substance and liquid being capable of flowing from the primary container to the final container via the outlet when the final container is coupled with the outlet.

3. The system as defined by claim 1 wherein the liquid is a diluting solution.

4. The system as defined by claim 1 wherein the primary container has a septum to sealingly contain the caustic substance.

5. The system as defined by claim 4 wherein the primary container has a top surface that is formed by the septum, the system further including a tube coupled through the septum to produce the outlet.

6. The system as defined by claim 4 further including a spike assembly capable of piercing through the septum in the primary container, the spike assembly having at least one spike forming an inlet for receiving the liquid and an outlet after piercing the septum.

7. The system as defined by claim 1 wherein the primary container includes an inlet for receiving the liquid.

8. The system as defined by claim 1 wherein the caustic substance has a pH that is greater than about 11.0.

9. The system as defined by claim 1 wherein the primary container is produced from materials capable of withstanding substantially immediate significant corrosion by the caustic substance.

10. The system as defined by claim 1 wherein the caustic substance is an anti-pathogen compound.
