Problems solved by technology

This reduces the amount of healthy skin covered by the dressing.
Consequently, covering the whole wound area and surrounding healthy skin with the same dressing type may create adverse conditions for certain areas of the wound or the surrounding skin, which may increase the healing time or even cause adverse effects such as secondary dermatitis.

[0080] The device 56 has been used for fabrication of a two layer wound dressing having a rectangular outer layer with a size of about 100 by 80 mm and a round internal layer having a diameter of about 50 mm. The electro-hydrodynamic method of microfiber deposition, described above, has been used for both the inner layer and outer layer with changes of material flow rate and electrostatic field value.

[0081] A mixture of polyvinilpirralidone (M=360,000) and poly-d,l-lactide (M=150,000), in ratio 1:10, and 80% of solvent ethyl acetate has been used. Flow rate of the mixture was 1 mL / min for the inner dressing layer and 2.5 mL / min for the outer dressing layer. Electrical field strength between the capillary and grounded support was 1.5 kV / cm for the inner dressing layer and 0.5 kV / cm for the outer dressing layer. The distance between the cartridge outlet and the surface was 10 cm. The velocity of the support relative the capillary was 0.5 cm / sec and scanning overlapping was 70%. The i...

Abstract

A method of treating a wound using a customized dressing. In the method, at least one wound characteristic is evaluated. A treatment need as a function of the at least one wound characteristic is determined. A dressing having a dressing characteristic responsive to the treatment need is fabricated and applied to the wound. A dressing for use therewith and an apparatus and system for fabricating the dressing are provided.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. provisional patent application No. 60 / 378,635 filed May 7, 2002, the entire content of which is incorporated herein by this reference.FIELD OF THE INVENTION [0002] The present invention generally relates to wound treatment and systems and methods of preparing a wound dressing. More particularly, it relates to a wound treatment including a dressing adapted to match the wound site. BACKGROUND OF THE INVENTION [0003] Currently, the common method of wound treatment is to cover the wound with a wound dressing. The wound dressing is manufactured as a precut sheet of multi-layer material of various shapes and sizes. The wound dressing is applied to cover the wound and a portion of the surrounding healthy skin. Sometimes the wound dressing is cut to reduce the size and to better fit the wound size and shape. This reduces the amount of healthy skin covered by the dressing. [0004] A typical wound commonly h...
