  • Publication number: 20180008494
    Abstract: The present invention provides a medical nursing pad for preventing bedsores. The medical nursing pad comprises a surface layer, a core body layer and a bottom layer. The core body layer has a fluff pulp and a super absorbent polymer material, and is covered by toilet paper. A dotted SAP is distributed on the core body layer. The SAP absorbs and retains an infiltrating liquid in an inversely funnelled SAP absorption region in the core body layer to minimize the reverse osmosis amount of the liquid absorbed by the medical nursing pad. Meanwhile, vapour separated from the liquid reaches the bottom layer through a longitudinal vapour channel formed by a gap among fluff pulp fibres with a certain density range in the core body layer, and is expelled from the medical nursing pad through a nanoscale breathable micro-pore on the bottom layer.
