The formation of a non-woven, free from organic solvent, formed through parallel formation of fibers on a collection device is disclosed. As the individual fibers are dry prior to contact with other fibers, the different contents of the various fiber types do not interact. However, when wetted, the fibers will start to be dissolved, or swell, and the different contents will be released and then interact. For the example of thrombin and fibrinogen, the interaction will initiate the formation of a fibrin coagulum by the cleavage of fibrinogen through the action of thrombin to form fibrin monomers that spontaneously polymerize to form a three dimensional network of fibrin. 112.-. (canceled)13. A method for preparation of a non-woven comprising the steps of:(a) ejecting an aqueous solution of a natural protein structure through a nozzle to form a natural protein structure fiber, wherein the aqueous solution comprises less than 25% low molecular weight alcohol; while(b) emitting pressurized air to attenuate or stretch the natural protein structure fiber; and(c) collecting the fibers on a collecting device.14. The method of claim 13 , wherein the pressurized air is emitted from air jet bores.15. The method according to claim 13 , wherein the natural protein structure is biodegradable.16.

Wound Dressing Inhibiting Lateral Diffusion Of Absorbed Exudate

Номер: US20130231623A1
Автор: Richard David A.
Принадлежит:

A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid. 1. A wound dressing comprising:a proximal hydrophilic layer fabricated from a first fibrous polymer and configured for placement adjacent to a portion of skin producing exudate to absorb the exudate; anda hydrophobic layer in contact with the proximal hydrophilic layer, the hydrophobic layer comprising a second fibrous polymer configured for receiving the exudate absorbed by the proximal hydrophilic layer and storing the exudate at inter-fiber gaps to inhibit lateral diffusion of the exudate in the wound dressing.2.

Wound Dressing Inhibiting Lateral Diffusion of Absorbed Exudate

Номер: US20150290041A1
Автор: Richard David A.
Принадлежит:

A wound dressing including a hydrophilic layer and a hydrophobic layer is described. The hydrophilic layer absorbs exudate from a wound and the hydrophobic layer absorbs the exudate from the hydrophilic layer and traps the exudate. Because the hydrophilic layer is used adjacent to the wound, the exudate is readily absorbed thereby reducing the risk of maceration and infection of the wound tissue by the exudate. The hydrophobic layer receives the absorbed exudate from the hydrophilic layer and traps the exudate through an interaction that in turn prevents lateral diffusion of the exudate through the bandage to healthy portions of the skin. The hydrophilic and hydrophobic layers are fabricated from polymer fibers that can be spun to include components that facilitate wound healing, such as poly(hexamethylene biguanide) and/or hyaluronic acid. 1. A wound dressing comprising:a proximal hydrophilic layer fabricated from a first fibrous polymer and configured for placement adjacent to a portion of skin producing exudate to absorb the exudate; anda hydrophobic layer having a first side in contact with the proximal hydrophilic layer and a second side opposite the first side, the hydrophobic layer comprising a second fibrous polymer including fibers that comprise fibers of poly(caprolactol) and poly(hexamethylene biguanide hydrochloride) in the fibers of poly(caprolactol), the second fibrous polymer configured for receiving the exudate absorbed by the proximal hydrophilic layer and storing the exudate at inter-fiber gaps to inhibit lateral diffusion of the exudate in the wound dressing.2. The wound dressing of claim 1 , wherein the second fibrous polymer of the hydrophobic layer undergoes a volume reduction upon storing the exudate at interstitial gaps.3. The wound dressing of claim 1 , wherein the first fibrous polymer of the proximal hydrophilic layer comprises fibers of poly(ethylene oxide) and poly(ethylene-co-vinyl alcohol) claim 1 , the fibers having an average ...
