REVERSIBLE CAVITARY TENSION MEMBRANE

摘要

The present invention's goal is to devise an apparatus (here-forth called ‘punch-ball’) made of a tension-reversible membrane that will assume a particular three-dimensional predetermined shape when under tension, apparatus that will border a central empty space, central space limited by the interior face of the membrane, and central space that will be in direct communication with the exterior space outside of the external face of the ‘punch-ball’ through orifices in the membrane (here-forth called ‘punches’), punches that will not decrease the ability of the membrane to exhibit a tension force. The punch-ball can be used freestanding or in connection with an object representing a confined space that will be abutting the exterior face of the punch-ball when the punch-ball is under tension. The punches will allow fluid to flow freely or solids to be transferred freely between the interior and exterior of the punch-ball membrane without any limitations to the initial flow through the cavity prior to the punch-ball membrane being deployed in the cavity, the interior face of the membrane being defined as surrounding the empty space inside the punch-ball while the exterior face of the membrane as facing the exterior of the punch-ball. The membrane will be provided with hinge borders (borders that will lack completely or partially the property of being under tension, and at same time have various degrees of elasticity or deformability), borders that will allow the punch ball shape to adapt to the shape of the cavity in which it will be deployed, or for the action to be undertaken. At the end of the action performed the tension in the membrane will cease, the punch-ball will be un-deployed and then removed from the location of action.

主权项

1. An apparatus for supporting a cavity structure without obstructing the flow of fluid through the cavity structure, the apparatus comprising:
an expandable membrane configured to transition between an expanded state and a shrunken state, wherein the membrane is a single layer, the membrane comprising:
an internal face and an external face opposite the internal face;a plurality of vacuolated spaces, the vacuolated spaces in fluid communication with each other within the membrane and configured to receive a pressurized fluid for exerting pressure on the internal face and the external face to place the expandable membrane in the expanded state; andat least one orifice disposed between the internal face and the external face, wherein the external face is in fluid communication through the orifice with an empty space defined by the internal face of the membrane when the membrane is in the expanded state.
