ABSTRACT:
Two layers of flexible material, each of which is resistant to the passage of fluids and microbes, include spacers between them, and are hermetically sealed, for maintaining reduced atmospheric pressure in the space between them. Open cell foam supported in the space is compressed by the layers until one of the layers is torn, upon which the resulting increase in atmospheric pressure in the space allows the foam to resile, increasing the space between the layers as a warning to the user of the break. An electric switch which is responsive to pressure change is in communication with the space to also signal a warning of the break.
