Abstract

A method for selectively dispensing fluid components through a bypass, the bypass having a fluid passage with an inlet, a first outlet that is unsealed, and a second outlet that is sealed, includes the steps of inserting a tubing line into the second outlet to unseal the second outlet, sealing the first outlet to prevent flow of fluid through the first outlet, and delivering a first fluid component into the inlet of the bypass and through the second outlet.

Claims

1. A method for selectively dispensing fluid components into a product bag attached to a tube set of a bulk compounder having at least one tubing line, a manifold, and a bypass having a fluid passage with an inlet, a first outlet in fluid communication with the manifold, and a second outlet in fluid communication with the product bag, the method comprising the steps of:

providing liquid components to be dispensed into a product bag wherein one of the liquid components is maintained separate from the other liquid components;

inserting a tubing line in fluid communication with the product bag into the second outlet;

blocking the first outlet in fluid communication to the manifold; and

dispensing a fluid component to be maintained separate from the other liquid components through the second outlet and into the product bag, independent of the manifold.

2. The method of claim 1, wherein the step of blocking the first outlet in fluid communication to the manifold comprises inserting a hollow probe end of the tubing line into the fluid passage and past the first outlet such that the probe end obstructs the first outlet and prevents fluid from flowing from the inlet to the first outlet.

3. The method of claim 1, wherein the liquid component to be maintained separate is a lipid solution.

4. The method of claim 1, wherein the step of inserting a tubing line into the second outlet, comprises opening a flow control device of the second outlet.

5. A method for selectively dispensing fluid components into a product bag attached to a tube set of a bulk compounder having at least one tubing line, a manifold, and a bypass having a fluid passage with an inlet and at least two outlets, the method comprising the steps of:

providing liquid components to be dispensed into a product bag;

inserting a tubing line in fluid communication with the product bag into the second outlet;

blocking the first outlet in fluid communication to the manifold; and

dispensing a fluid component through the second outlet and into the product bag, independent of the manifold.

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

7. The method of claim 5, further comprising the steps of:

removing the tubing line in fluid communication with the product bag from the second outlet;

blocking the second outlet;

unblocking the first outlet in fluid communication to the manifold; and

dispensing the fluid component through the first outlet and manifold.

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.

10. The method of claim 7, wherein the step of unblocking the first outlet is completed by the step of removing the tubing line from the second outlet.

11. A method for selectively dispensing fluid components through a bypass, the bypass having a fluid passage with an inlet, a first outlet in fluid communication with a first bag compartment, and a second outlet that is sealed:

inserting a tubing line into the second outlet to unseal the second outlet;

connecting the tubing line in fluid communication with a second bag compartment that is fluidly separate from the first bag compartment;

sealing the first outlet to prevent flow of fluid to the first bag compartment; and

delivering a first fluid component into the inlet of the bypass and through the second outlet to the second bag compartment.

12. The method of claim 11, wherein the step of sealing the first outlet is completed by the step of inserting a tubing line into the second outlet.

13. The method of claim 11 further comprising the steps of:

stopping delivery of the first fluid component into the inlet of the bypass;

removing the tubing line from the second outlet;

sealing the second outlet to prevent flow of fluid to the second bag compartment;

unsealing the first outlet; and

delivering a second fluid component into the inlet of the bypass and through the first outlet to the first bag compartment.

14. The method of claim 13, wherein the step of sealing the second outlet is completed by the step of removing the tubing line from the second outlet.

15. The method of claim 13, wherein the steps of sealing the second outlet to prevent flow of fluid to the second bag compartment and unsealing the first outlet are both completed by the step of removing the tubing line from the second outlet.

16. The method of claim 11 wherein the first bag compartment and second bag compartment are located in the same fluid bag.
