Abstract
There is provided a pressure-equalizing housing device, including a rigid housing having a coupling end and configured to contain at least one instrument. The coupling end of the housing is adapted to be sealable to a radiation transmittable surface. An opening made in a wall of the housing enables fluid to pass therethrough, and the housing and surface delimit an interior space communicating with the exterior of the housing via the opening. There is also provided a pressure-influenced member forming an expandable and retractable volume body, a portion of which member is located adjacent to, or the interior of which member communicates with, the opening, for equalizing the pressure inside and outside the housing.
Claims21
1-21. (canceled)
A pressure-equalizing device, comprising:
- a housing having a coupling end and configured to contain at least one instrument;
- said coupling end of the housing is adapted to be at least indirectly sealable to an optically transparent surface;
- an opening made in a wall of said housing enabling fluid to pass therethrough;
- said housing and surface delimiting an interior space communicating with the exterior of the housing via said opening, and
- a pressure-influenced member forming an expandable and retractable volume body, a portion of which member is located adjacent to, or the interior of which member communicates with, said opening, for equalizing the pressure inside and outside said housing.
