Abstract

The invention provides a system for preventing fluid exchange between the interior and exterior of containment enclosures such as process-, hazard-, and research-enclosure systems generally, gloveboxes, containment systems, isolation systems, confinement systems, cleanrooms, negative air systems, and positive air system areas while simultaneously providing material transfer into and out of the enclosures. The invention also provides a method for transporting material into or out of a containment structure.

First claim

The embodiment of the invention in which an exclusive property or privilege is claimed is defined as follows:

1. A system for preventing fluid exchange between the interior and exterior of a containment enclosure during material transport, the system comprising:
a) a materials transport tunnel wherein the materials transport tunnel comprises a cylinder adapted to be received by a region of the enclosure forming an aperture so that a hermetic seal exists between the cylinder and the aperture wherein the cylinder has continuous solid sides impervious to fluids; and
b) a first canister coaxially positioned within, and in slidable communication with the cylinder such that a hermetic seal exists between the first canister and the enclosure and a forward end of the first canister is in contact with an interior atmosphere of the enclosure and an aft end of the first canister is not in contact with the interior atmosphere, wherein the first canister is adapted to pass completely through the tunnel;
c) a second canister coaxially aligned with the first canister and contacting the aft end of the first canister.

2. The system as recited in claim 1 wherein the first and second canisters are simultaneously accommodated by the cylinder.

3. The system as recited in claim 2 wherein an airlock is formed between each of the canisters.

4. The system as recited in 2 wherein the first and second canisters each defines a central aperture and a longitudinally extending annular space circumscribing the aperture.

5. The system as recited in claim 4 further comprising an elongated flexible sleeve having a first end attached to a first end of the canister within the annular space and a second free end adapted to receive material located external of or internal of the enclosure.

6. The system as recited in claim 4 wherein a first end of the annular space is adapted to attach to a first end of a flexible tubular poly sleeve so as to reversibly stow the tubular poly sleeve within the annular space.

7. The system as recited in claim 1 wherein the first canister can be pushed through the cylinder independently of the second canister.

8. The system as recited in claim 1 wherein the aperture is a glove port formed in vertically disposed walls of the enclosure.

9. The system as recited in claim 8 wherein the glove port is 8″ in diameter and is formed in vertically disposed walls of a glove box.

10. The system as recited in claim 1 wherein tools, reagents, fluid canisters, aggregate material, and electronic componentry, may be transported via the first and second canisters into the enclosure.

11. The system as recited in claim 1 wherein the forward end is adapted to be pulled by a gloved hand of a user of the system.
