The invention relates to a wound dressing comprising a microbial-derived cellulose for treatment of specific types of chronic wounds, including pressure sores, venous and diabetic ulcers. The wound dressing is capable of donating liquid to dry substrates is also capable of absorbing exudating wounds.

Microbial cellulose wound dressing for treating chronic wounds

This application describes a bioresorbable biocellulose suitable for medical and surgical applications. In particular, the invention describes periodate oxidized microbial cellulose that can be produced to have any mechanical and degradation profile, depending on the desired application of the oxidized cellulose.

Oxidized microbial cellulose and use thereof

The invention relates to a wound dressing comprising a microbial-derived cellulose for treatment of specific types of chronic wounds, including pressure sores, venous and diabetic ulcers. The wound dressing is capable of donating liquid to dry substances is also capable of absorbing exudating wounds.

This invention relates to a process for preparing bioabsorbable oxidized cellulose comprising combining cellulose material, with nitrogen dioxide and a nonaqueous solvent chosen from the class of perfluorinated tertiary amines. This invention also relates to a method of oxidizing cellulose material comprising introducing a solvent into the vessel, circulating the solvent through the cellulose material, adding nitrogen dioxide to said vessel containing the solvent and cellulose in the required amounts, circulating the solution for 7 to 24 hours while controlling the reaction temperature, and isolating the oxidized material. Preferably, isolation of the oxidized product is followed by first washing the oxidized cellulose material with cold water, then washing the oxidized cellulose material with an aqueous alcohol solution several times, then washing the material with 100% alcohol several times, and finally drying the oxidized material.
