Abstract

A controlled environment enclosure comprises a robotic arm manipulation system used to protect and unprotect a fluid path within the controlled environment enclosure. The apparatus allows the fluid path to be protected against dangerous decontamination vapors and chemicals before the controlled environment enclosure is decontaminated, the method not requiring the use of gloves or other means that degrade the integrity of the controlled environment enclosure. The apparatus similarly allows the fluid path to be unprotected for use without the use of gloves, the method not requiring the use of gloves or other means that degrade the integrity of the controlled environment enclosure when decontaminated is completed. The apparatus and method allow for the protecting, unprotecting and decontaminating sequences to be automated.

First claim

The invention claimed is:

1. An apparatus for protection and unprotection of transporting a fluid within an aseptic controlled environment enclosure, comprising:
a dispensing system structured and configured to maintain the aseptic condition having:
a. a fluid path, the fluid path including a fluid source, a tube extending from the fluid source and terminated by a fill needle with a removable sheath,
b. a remotely operated manipulation system for protection and/or unprotection of the fluid path; and
c. a tamper-evident device positioned to reveal a breach of seal between the sheath and the fill needle.

2. The apparatus of claim 1 wherein the remotely operated manipulation system includes a robotic arm manipulation system.

3. The apparatus of claim 2 wherein the robotic arm manipulation system further comprises an end tool configured to engage the fill needle and the removable sheath.

4. The apparatus of claim 3 wherein the robotic arm manipulation system further comprises a tool flange configured to move the fill needle within the controlled environment enclosure.

5. The apparatus of claim 1 further including a removal station that includes a surface operative to interact with part of the sheath.

6. The apparatus of claim 1 wherein the remotely operated manipulation system includes a robot end tool including at least one surface that is shaped to hold the fill needle.

7. The apparatus of claim 1 wherein the fluid path is a pre-sterilized unit.

8. The apparatus of claim 1 wherein the fluid path further comprises a filter.

9. The apparatus of claim 1 wherein the fluid path further comprises a peristaltic pump.

10. An apparatus for transporting a fluid within an aseptic controlled environment enclosure, comprising:
a. means for conveying the fluid, the conveying means being structured and configured to maintain the aseptic condition, the conveying means including a fluid path comprising a fluid source coupled to a tube with the tube terminating by a fill needle,
b. means for sealing the fill needle of the fluid conveying means, the sealing means being structured and configured to maintain the aseptic condition; and
c. remotely operated means for protecting and/or unprotecting the fluid conveying means, the remotely operated means being structured and configured to maintain the aseptic condition.

11. The apparatus of claim 10 wherein the remotely operated means includes a robotic arm manipulation system.

12. The apparatus of claim 11 wherein the robotic arm manipulation system further comprises an end tool configured to engage the fluid conveying means.

13. The apparatus of claim 12 wherein the robotic arm manipulation system further comprises a tool flange configured to move the fluid conveying means within the controlled environment enclosure.

14. The apparatus of claim 10 further including a removal station that includes a surface operative to interact with the fluid conveying means.

15. The apparatus of claim 10 wherein the remotely operated means includes a robot end tool including at least one surface that is shaped to hold the fluid conveying means.

16. The apparatus of claim 10 wherein the fluid conveying means includes a pre-sterilized unit.

17. The apparatus of claim 10 wherein the fluid conveying means further comprises a filter.

18. The apparatus of claim 10 wherein the fluid conveying means further comprises a peristaltic pump.

19. The apparatus of claim 1 further comprising a pump, wherein the pump is in communication with the fluid source.

20. The apparatus of claim 10 wherein the fluid conveying means includes a pump.

21. The apparatus of claim 19 wherein the pump is disposed within the controlled environment enclosure.

22. The apparatus of claim 20 wherein the pump is disposed within the controlled environment enclosure.
