Urine quantifying bed pad

A method of detecting the presence of and approximating a volume of a fluid, the method comprising:

• providing an absorbent pad, the absorbent pad comprising:
• a top layer comprising a first sheet, the first sheet comprising:
• an outward face and an inward face, wherein the first sheet comprises a wicking material, the first sheet further comprising a volume approximation grid having a plurality of fluid volume estimation regions, wherein at least one fluid volume estimation region is encircled by a subset of adjacent fluid volume estimation regions, each of which is contiguous with the at least one fluid volume estimation region along a portion of a perimeter of the at least one fluid volume estimation region;
• and
• a second sheet, the second sheet comprising an absorbent material, the second sheet attached to the inward face of the first sheet;
• and
• a bottom layer comprising an outward face and an inward face, the inward face of the bottom layer attached to the second sheet;
• and
• a visual fluid indicator disposed on at least a portion of the bottom layer, wherein the visual fluid indicator is configured to migrate to the first sheet and produce a visible color change on the outward face of the first sheet;
• contacting the absorbent pad with the fluid;
• and
• determining a number of regions on the first sheet having the fluid thereon.

A method of manufacturing an absorbent pad, the method comprising:

• providing a top layer comprising a first sheet and a second sheet, the first sheet having an outward face and an inward face,
• the second sheet attached to the inward face of the first sheet, wherein the first sheet comprises a wicking material, wherein the second sheet comprises an absorbent material;
• providing a bottom layer comprising an outward face and an inward face;
• forming a volume approximation grid having a plurality of fluid volume estimation regions on at least a portion of the first sheet, wherein at least one fluid volume estimation region is encircled by a subset of adjacent fluid volume estimation regions, each of which is contiguous with the at least one fluid volume estimation region along a portion of a perimeter of the at least one fluid volume estimation region;
• applying a visual fluid indicator on the bottom layer, wherein the visual fluid indicator is configured to migrate to the first sheet and produce a visible color change on the outward face of the first sheet;
• and
• affixing the bottom layer having the visual fluid indicator applied thereon to the top layer.
