Barrier isolator port assembly
A barrier isolator port assembly for connecting to a conventional docking port of an isolated enclosure is provided. The port assembly includes an annular body, a door assembly and a lock. The annular body is configured to engage a docking port of the isolated enclosure. The port assembly also includes a door assembly mountable within the annular body and a lock operatively connected to the annular body. The lock includes a lever and a pin. The lever is pivotably connected to the annular body about a pivoting member and configured to pivot about the pivoting member to removably insert the pin into the recess of the door assembly.
1. A barrier isolator port assembly comprising:
an annular body configured to engage a docking port of an isolated enclosure, the annular body having an outside surface with an annular-body radius and including a thru-hole having a longitudinal axis at an angle relative to a radial direction of the angular body;
a door assembly mountable within the annular body and movable between an open position to access the enclosure and a closed position preventing access to the enclosure, the door assembly including a periphery having a recess alignable with the thru-hole when the door assembly is in the closed position; and
a lock operatively connected to the annular body, the lock including:
a lever having first and second ends and a middle portion between the first and second ends, the middle portion being pivotably connected to the annular body about a pivoting member, a bottom portion of the lever having a curved portion with a lever-radius substantially the same as the annular-body radius, and
a pin connected to the second end, the lever being pivotable to move between a first position with a portion of the pin within the thru-hole and a second position with the pin removably inserted in the recess of the door assembly.
2. The barrier isolator port assembly of claim 1 , wherein the annular body comprises three thru-holes, the periphery of the door assembly includes three recesses, and the port assembly includes three locks.
3. The barrier isolator port assembly of claim 1 , wherein the annular body comprises a plurality of thru-holes, the periphery of the door assembly includes a plurality of recesses, and the port assembly includes a plurality of locks.
4. The barrier isolator port assembly of claim 3 , wherein each of the plurality of thru-holes, the plurality of recesses, and the plurality of locks are circumferentially and equidistantly spaced apart.
5. The barrier isolator port assembly of claim 1 , wherein the lock is operatively connected to a non-mating side of the annular body.
6. The barrier isolator port assembly of claim 5 , wherein the lock pivots about an axis substantially parallel to a longitudinal axis of the annular body.
7. The barrier isolator port assembly of claim 1 , wherein the door assembly further includes a wall within the periphery comprising a ferromagnetic material.
8. The barrier isolator port assembly of claim 1 , wherein the annular body further comprises:
an outer surface; and
an inner surface,
wherein the thru-hole extends from the outer surface to the inner surface.
9. The barrier isolator port assembly of claim 8 , wherein the thru-hole of the annular body is a cylindrical thru-hole having a longitudinal axis generally orthogonal to a longitudinal axis of the annular body, and wherein the longitudinal axis of the thru-hole is at an angle relative to a radial direction of the annular body.
10. The barrier isolator port assembly of claim 9 , wherein the angle is about 5 to 20 degrees.
11. The barrier isolator port assembly of claim 1 , wherein the annular body further comprises:
a radially outwardly extending flange about a mating side of the annular body configured to engage the docking port, the flange including:
a mating surface; and
a non-mating surface.
12. The barrier isolator port assembly of claim 11 , wherein the flange of the annular body further comprises a seal to hermetically seal the annular body to the docking port.
13. The barrier isolator port assembly of claim 11 , wherein the flange of the annular body further comprises:
an annular recess extending from the mating surface; and
a sealing member configured to reside within the annular recess.
14. The barrier isolator port assembly of claim 1 , further comprising a connector connectable to a non-mating side of the annular body.
15. The barrier isolator port assembly of claim 14 , further comprising a container connectable to the connector.
16. The barrier isolator port assembly of claim 1 , further comprising a resilient member circumscribing the pin.
17. The barrier isolator port assembly of claim 16 , further comprising a annular member configured about the pin and above to the resilient member.
18. The barrier isolator port assembly of claim 1 , wherein the recess of the door assembly extends partially through the body of the door assembly.
19. The barrier isolator port assembly of claim 1 , wherein the second end of the lever has a thru-hole and the pin is pivotable within the thru-hole.
20. The barrier isolator port assembly of claim 1 , wherein the lock is unlockable by a cam assembly of an alpha-side docking port when the barrier isolator port assembly is engaged with the alpha-side docking port.
