Abstract

A method for producing sterile solution product bags includes positioning a manifold assembly onto a filling machine. The manifold assembly includes a plurality of bags, a first filter, and a connection line in fluid communication with the first filter. Each of the plurality of bags includes a bladder and a stem in fluid communication with the bladder and with the connection line. The method includes activating a pump and at least partially filling one or more of the bladders by pumping fluid through the feed line, the first filter, and the connection line. The method includes sealing the stem of each of the filled product bags at a location between the connection line and the bladder, thereby creating one or more at least partially filled and sealed product bags. The method includes separating each of the at least partially filled and sealed product bags from the connection line.

First claim

What is claimed:

1. A method for producing sterile solution product bags, the method comprising:
positioning a manifold assembly onto a filling machine, the manifold assembly including a plurality of bags, a filter, and a connection line in fluid communication with the filter, wherein each of the plurality of bags includes a bladder and a stem having a first end in fluid communication with the bladder and a second end in fluid communication with the connection line;
at least partially filling one or more of the bladders associated with the plurality of bags by pumping fluid through the filter and the connection line, thereby creating one or more partially filled product bags;
sealing the stem of each of the at least partially filled product bags at a location between the connection line and the bladder of the at least partially filled product bags, thereby creating one or more at least partially filled and sealed product bags having a seal;
separating, at the seal, each of the at least partially filled and sealed product bags from the connection line;
determining an adequacy of the seal in which the seal is inadequate when at least one of (a) and (b) is detected: (a) failing to meet a sealing time threshold, and (b) releasing a sealing tool when a melting point of the stem is reached such that the passageway is sealed; and
activating an alarm when an inadequate seal is formed in the stem.

2. The method of claim 1 , further comprising aligning a sealing tool at the location between the connection line and each bladder of the at least partially filled product bags.

3. The method of claim 2 , wherein aligning the sealing tool includes inserting the sealing tool with a registration position adjacent to the stem one of the plurality of bags, the filling machine including a registration position for each of the plurality of bags.

4. The method of claim 3 , further comprising aligning a cutting tool at the location between the connection line and each bladder of the at least partially filled product bags such that a blade of the cutting tool is aligned with a center point of the seal formed in the stem of each of the at least partially filled and sealed product bags from the connection line.

5. The method of claim 4 , wherein aligning the cutting tool includes inserting the cutting tool into the registration position.

6. The method of claim 1 , wherein separating includes cutting the stem of each at least partially filled and sealed product bags at the location between the connection line and the bladders, thereby creating a cut in the stem such that the stem is sealed at a first side and a second side of the cut.

7. The method of claim 1 , further comprising displaying a first identifier to begin sealing and displaying a second identifier to stop sealing.

8. The method of claim 1 , further comprising performing a filter integrity test on the filter after separating the filter from the manifold assembly.

9. The method of claim 1 , wherein at least partially filling one or more of the bladders associated with the plurality of bags includes filling a first bag before filling a second bag.

10. The method of claim 9 , wherein sealing the stem of each at least partially filled product bags includes sealing a stem associated with the first bag while the second bag is being at least partially filled with fluid.

11. The method of claim 1 , wherein positioning the manifold assembly includes attaching a rack holding the manifold assembly to the support wall of the filling machine, the rack including a plurality of compartments for holding the plurality of bags of the manifold assembly.
