Abstract

A bypass for a tube set for directing the flow of a fluid component includes an inlet passage for fluid connection with a source of said fluid component, an outlet passage for fluid connection with a first bag compartment, and a bypass passage for fluid connection with a second bag compartment. A flow control device in the bypass passage is operable in a first position in which the flow control device seals the bypass passage, and a second position in which the flow control device unseals the bypass passage to receive a tubing line connected with said second bag compartment.

Claims

1. A bypass for a tube set for directing the flow of a fluid component, said bypass comprising:

an inlet passage for fluid connection with a source of said fluid component;

a first outlet passage for fluid connection with a first bag compartment;

a second outlet passage for fluid connection with a second bag compartment; and

a flow control device in the second outlet passage, the flow control device being operable in a first position in which the flow control device seals the second outlet passage, and a second position in which the flow control device unseals the second outlet passage upon connection of a tubing line connected with said second bag compartment, wherein the second outlet passage extends transversely to the first outlet passage, the bypass and second outlet passage adapted to telescopically receive said tubing line in a position that obstructs the first outlet passage to prevent flow between the inlet passage and the first outlet passage.

2. The bypass of claim 1, wherein the flow control device comprises a self-sealing membrane.

3. The bypass of claim 1, wherein the second outlet passage extends generally parallel to the inlet passage.

4. The bypass of claim 1, wherein the inlet passage and first outlet passage form an angle θ

of less than 90 degrees.

5. The bypass of claim 1, wherein the second outlet passage extends in a first direction and the first outlet passage extends in a second direction, the first and second directions being separated by an obtuse angle.

6. The bypass of claim 4, wherein the first and second directions are separated by an angle of about 135 degrees.

7. The bypass of claim 1 comprising a flip-top cap for selectively closing the second outlet passage.

8. A bypass for a tube set for directing the flow of a fluid component, said bypass comprising:

an inlet passage for fluid connection with a source of said fluid component;

a first outlet passage for fluid connection with a first bag compartment;

a second outlet passage for fluid connection with a second bag compartment; and

a flow control device in the second outlet passage, the flow control device being operable in a first position in which the flow control device seals the second outlet passage, and a second position in which the flow control device unseals the second outlet passage upon connection of a tubing line connected with said second bag compartment, wherein the second outlet passage and inlet passage form a continuous passage through the bypass to facilitate insertion of the tubing line into the second outlet passage, through the bypass, and through the inlet passage.
