ABSTRACT:
A device and method for testing the integrity of a vaginal diaphragm having an annular ring about a membrane desired to be nonporous consists of a base member defining a surface for engaging the ring in sealing relationship and defines, with the membrane, a pressure chamber, a clamp for clamping the ring in sealing relationship upon the surface, apparatus for creating an inflating pressure condition in the chamber of a level predetermined to cause loss of air from the chamber through the membrane if the membrane has in excess of predetermined maximum degree of porosity, and an indicator of loss of air from within the chamber. Preferably the clamp is defined by a cover, and the device is in the form of a protective carrying case for the diaphragm.
