Abstract

An on-diaper body fluid screening device (100), comprising a stack of the following sheets: a surface sheet (110) permeable to body fluid, a collection sheet (120) impervious to body fluid, a testing sheet (130), which is body fluid absorbent and provided with colorimetric assay reaction pads (131), and which is provided with a body fluid barrier network (132) forming body fluid channels (134) between an inlet section (135) and the colorimetric assay reaction pads (131), a protection sheet (140) impervious to body fluid, and a transparent readout sheet (150), through which the assay reaction pads (131) are visible. The protection sheet (140) comprises pad receiving openings (142). The collection sheet (120) comprises an inlet hole (125) which is arranged over the inlet section (135). A swelling component (702) is arranged in association with the inlet hole (125) and an inlet hole closing member (601).
