Abstract

A bypass used for selectively dispensing fluid components includes a fluid passage with an inlet, a first outlet for fluid communication with a first collecting container, and a second outlet for fluid communication with a second collecting container. A method for dispensing fluid components using the bypass includes the steps of providing fluid components to be dispensed, with one fluid component isolated from the other fluid components, blocking the first outlet of the bypass, and dispensing the isolated fluid component through the second outlet and into the second collecting container.

Claims

1. A method for selectively dispensing fluid components employing a bypass, the bypass having a fluid passage with an inlet, a first outlet for fluid communication with a first collecting container, and a second outlet for fluid communication with a second collecting container, the method comprising the steps of:

providing the fluid components to be dispensed, wherein one of the fluid components is isolated from the other fluid components;

blocking the first outlet of the bypass; and

dispensing the isolated fluid component through the second outlet and into the second collecting container.

2. The method of claim 1, wherein the step of blocking the first outlet of the bypass comprises inserting a tubing line into the second outlet and past the first outlet such that the tubing line obstructs the first outlet and prevents the isolated fluid component from flowing from the inlet to the first outlet.

3. The method of claim 1, wherein the isolated fluid component is a lipid solution.

4. The method of claim 1, wherein the first collecting container is a first chamber within a product container, and the second collecting container is a second chamber within said product container.

5. A method for selectively dispensing fluid components employing a manifold and a bypass having a fluid passage with an inlet and at least two outlets, the method comprising the steps of:

providing the fluid components to be dispensed;

blocking a first of the at least two outlets of the bypass;

connecting a second of the at least two outlets of the bypass in fluid communication with a container having a first chamber and a second chamber; and

dispensing a fluid component through the second outlet and into the first chamber of the container, independent of the manifold.

6. The method of claim 5, wherein the step of blocking the first outlet of the bypass comprises inserting a tubing line into the fluid passage and past the first outlet such that the tubing line obstructs the first outlet and prevents fluid from flowing from the inlet to the first outlet.

7. The method of claim 6, further comprising the steps of:

unblocking the first outlet of the bypass by removing the tubing line from the fluid passage;

blocking the second outlet of the bypass;

connecting the first outlet in fluid communication with the second chamber of the container via the manifold; and

dispensing the fluid component through the first outlet and into the second chamber of the container.

8. The method of claim 7, wherein the step of blocking the second outlet comprises sealing a membrane of the second outlet.

9. The method of claim 7, wherein the step of blocking the second outlet comprises covering the second outlet with a flip-top cap.
