Experimental investigation of a quasi-sessile droplet absorption into a capillary

The primary goal of a wound dressing design and development is to accelerate the healing process, making the selection of an appropriate dressing type crucial. The complex topology of wound dressings presents challenges in visualizing the flow within their porous structure. However, the absorption of wound exudate by dressings can be investigated through high-resolution laboratory experiments. As a first step, an experimental study examined how exudate is absorbed into a single capillary tube from a quasi-sessile droplet. The findings showed that higher exudate viscosity leads to slower absorption and alters its behaviour inside the capillary tube.
