Abstract
In some embodiments, an apparatus includes a housing and a purge valve. The housing defines a cavity and a lumen extending from a volume of the cavity to a volume outside the cavity. The purge valve is disposed within the lumen and includes an occlusion member. A portion of the occlusion member has a width substantially equal to a width of an end portion of the lumen such that the portion of the occlusion member is disposed within the end portion of the lumen when the purge valve is in a first configuration. The portion of the occlusion member being disposed outside the end portion of the lumen when the purge valve is in a second configuration.

-25. (canceled)
An apparatus, comprising:
- a housing defining a cavity and a lumen, the lumen defining a pneumatic path extending from a first volume of the cavity to a second volume outside the cavity,
- an occlusion member operably coupled to the housing and configured to be movable between a first position, in which the occlusion member obstructs the pneumatic path, and a second position, in which the pneumatic path fluidically couples the first volume of the cavity to the second volume outside the cavity;
- and
- a semi-permeable material having a porosity disposed in the pneumatic path defined by the lumen, the porosity selected to allow predetermined gases to pass therethrough while being substantially impermeable to liquids.
An apparatus, comprising:
- an occlusion member disposed within a lumen, the occlusion member configured to pneumatically isolate a volume defined by a housing from a volume outside the housing when in a first position;
- at least one biased member disposed adjacent the occlusion member and configured to bias the occlusion member in the first position;
- a retaining member configured to keep the occlusion member and the at least one biased member within the lumen;
- and
- at least one semi-permeable material disposed within the lumen to allow gases to pass therethrough while being substantially impermeable to liquids,
- wherein the volume defined by the housing is in pneumatic communication with the volume outside the housing via the lumen when the occlusion member is in a second position.
