An absorbent wound dressing comprises a hydrophilic porous substrate and polymer-stabilized silver nanoparticles distributed throughout the porous substrate. The silver nanoparticles have a particle size d.sub.50 in the range of about 45 nm to about 85 nm and the silver nanoparticles are present in the substrate in an amount of about 0.16% to about 1.5% by weight of the total weight of the substrate. The wound dressing produces a 7-day log reduction of 4 or more for bacteria in accordance with the Modified AATCC Test Method 100. The wound dressing is also non-cytotoxic in accordance with ISO 10993-5 standard procedure for medical device cytotoxicity assessment.

The present invention relates to an absorbent structure and an absorbent article containing said absorbent structure. The absorbent structure, having a sequence of layers connected together, comprises a first outer absorbent layer made from airlaid material, a second outer absorbent layer made from airlaid material, and a fluid storage layer made from airlaid material arranged between the first and second outer absorbent layers, wherein the airlaid material of the first outer absorbent layer comprises first cellulose fibres, the airlaid material of the second outer absorbent layer comprises second cellulose fibres and the airlaid material of the fluid storage layer comprises third cellulose fibres and super-absorbent components, wherein the first and second cellulose fibres have a lower pH value than the third cellulose fibres and the pH value of the first and second cellulose fibres is less than 5.0.

The present invention relates to a medicated gauze impregnated with a dehydrated aloe vera extract. The medicated gauze is designed to treat deep wounds, topical burns and dry skin. The medicated gauze is produced by soaking the gauze in an aloe vera extract, drying the gauze in a sterile dehydrator, and then rolling the dried gauze into packages. When the medicated gauze is applied to a wound, the dehydrated aloe vera extract is hydrated by the patient's body moisture to create an aloe vera gel environment conducive to preventing infection and promoting wound healing while avoiding damage to surrounding skin.

Molecular iodine-infused catheters disclosed herein have biocidal effects and may be used to treat or prevent urinary tract infection (UTI). Other molecular iodine-infused polymers, articles, and products, and their preparation and uses are also disclosed.

The present invention relates to a superabsorbent polymer and a method for producing the same. The superabsorbent polymer includes a core layer polymerized with monomers having carboxylic group, a first shell layer formed from a surface crosslinking agent, and a second shell layer formed from zingiberaceae extracts. By a surface modification on the first shell layer performed from a specific amount of the zingiberaceae extracts, the superabsorbent polymer produced according to the method for producing the same has a good antimicrobial property and deodorizing effects, and retains an original absorbent property.

A filter is treated with a reduced amount of a halo active aromatic sulfanomide compound of Formula (I):
