Abstract
Provided is a patch including at least one pressure-absorbing member, the pressure absorbing member formed of a resilient material and having at least a first surface, the at least first surface is configured with a plurality of projections extending therefrom and a plurality of channels crossing one another at a plurality of intersections, an outermost surface of said plurality of projections lies along a projections plane of the pressure-absorbing member, the projections being deformable when subjected to pressure applied to the patch, so as to absorb at least some of the applied pressure.

A method of manufacturing a pressure-absorbing patch comprising a pressure-absorbing member, wherein said pressure-absorbing member has a plurality of projections extending therefrom with an outermost surface extending along a projections plane, and a plurality of channels, with at least one fluid reservoir disposed along at least one channel, the method comprising:
- obtaining a negative mold of said pressure-absorbing member;
- preparing a mixture of a material for forming the pressure-absorbing member;
- pouring said mixture into said mold;
- allowing the mixture to solidify;
- introducing a fluid into said at least one fluid reservoir in the molded structure;
- and
- applying a sealing layer to the pressure-absorbing member along said projections plane of the pressure-absorbing member, so as to seal the plurality of channels.
A method of absorbing, via a pressure-absorbing patch, an external pressure exerted on a body by a pressure producing source, the method comprising:
- obtaining a patch comprising at least one pressure-absorbing member, wherein the pressure-absorbing member is formed of a resilient material and has at least a first surface, wherein said at least said first surface is configured with a plurality of projections extending therefrom and a plurality of channels crossing one another at a plurality of intersections, and wherein an outermost surface of said plurality of projections lies along a projections plane of the pressure-absorbing member;
- and
- introducing said patch in-between said body and said pressure producing source, directly or indirectly, so as to allow said projections to deform when subjected to said external pressure, said projections thereby absorbing at least some of said external pressure.
