Abstract
The present invention relates to an externally operated alpha port for a rapid transfer port (RTP) system such as those found in isolation barrier systems. Means are provided for the actuation by the operator of the alpha port door locking system externally of the isolation barrier to facilitate the locking and unlocking of the alpha port door without requiring gloved entry into the isolation barrier. Means are also provided for opening and closing of the alpha port door with the actuation by the operator of a lever external to the isolation barrier.
Claims5
An externally operated alpha port system for a rapid transfer port (RTP) system, comprising:
- a) a mounting plate sealingly attached to an isolator barrier chamber having an RTP port system;
- b) an alpha port assembly, comprising:
- i. a flange assembly fixed to said mounting plate;
- ii. a door assembly hingedly connected to said flange assembly configured to swing into an internal volume of said isolator barrier chamber;
- c) a door locking actuator assembly, comprising:
- i. a first door locking element fixed to said door assembly;
- ii. a second door locking element rotatably attached to said flange assembly configured to operatively engage with said first door locking element;
- iii. a door locking body assembly fixedly attached to said mounting plate in a sealed manner, said door locking body assembly defining a first opening extending through said mounting plate, said door locking body assembly configured to operatively engage said second door locking element;
- iv. a door locking lever operatively connected to said door locking body assembly and extending through said first opening to provide door locking functionality from a position external to said isolator barrier chamber;
- d) a door opening actuator assembly, comprising:
- i. a first door hinge element fixed to said flange assembly;
- ii. a second door hinge element fixed to said door assembly and rotatably attached to said first door hinge element;
- iii. a door opening body assembly fixedly attached to said mounting plate in a sealed manner, said door opening body assembly defining a second opening extending through said mounting plate, said door opening body assembly configured to operatively engage said second door hinge element;
- iv. a door opening lever assembly operatively connected to said door opening body assembly and extending through said second opening to provide door opening functionality from a position external to said isolator barrier chamber,
- wherein to unlock and open said door assembly a user first actuates said door locking lever and then actuates said door opening lever assembly, and to close and lock said door assembly the user actuates said door opening lever assembly and then actuates said door locking lever.
