Device for collecting and absorbing urine

Claim 1

A device for collecting and absorbing urine, comprising: a laminate having a plurality of layers including a layer of outer plastic casing and a layer of material permeable to urine connected to said layer of plastic casing by sealing along the peripheral edges of each layer, said sealing forming an outer seam contour along the top, bottom and sides of the device; said sealing defining an expandable space comprising the interior of the laminate; an absorption body located in the expandable space comprising tissue integrated with a super-absorbent polymer which upon absorption expands to form a gel; said absorption body being narrower than said laminate and located centrally within said laminate such that the difference between the outer seam contour and the absorption body forms outer flaps along the sides of the laminate; said laminate being folded a first time transversely to said outer flaps approximately near the center of said laminate so that the side edges of said laminate are in contact and the outer flaps overlap themselves in parallel; said side edges of said laminate being sealed together where they contact forming a pocket; said outer flaps being folded over the absorption body at an angle with respect to the outer seam contour of the device; and a patch of releasable adhesive located between the outer flaps and the main absorption body for adhering the outer flaps to the main absorption body prior to said absorption and for releasing said outer flaps from said absorption body when the absorption body assumes the gel phase, said released outer flaps automatically unfolding to achieve an expansion of the pocket.

Claim 2

A device for collecting and absorbing urine, comprising: a laminate having a plurality of layers including a layer of outer plastic casing and a layer of material permeable to urine connected to said layer of plastic casing by sealing along the peripheral edges of each layer, said sealing forming an outer seam contour along the top, bottom and sides of the device; said sealing defining an expandable space comprising the interior of the laminate; an absorption body located in the expandable space comprising tissue integrated with a super-absorbent polymer which upon absorption expands to form a gel; said absorption body being narrower than said laminate and located centrally within said laminate such that the difference between the outer seam contour and the absorption body forms outer flaps along the sides of the laminate; said laminate being folded a first time transversely to said outer flaps approximately near the center of said laminate so that the side edges of said laminate are in contact and the outer flaps overlap themselves in parallel; said side edges of said laminate being sealed together where they contact forming a pocket; said outer flaps being folded over the absorption body at an angle with respect to the outer seam contour of the device; and a patch of releasable adhesive located between the outer flaps and the main absorption body for adhering the outer flaps to the main absorption body prior to said absorption and for releasing said outer flaps from said absorption body when the absorption body assumes the gel phase, said released outer flaps automatically unfolding to achieve an expansion of the pocket.
