Problems solved by technology

Such a product certainly has good autodissolving capabilities while maintaining its cohesion during its removal without any "gel-blocking" phenomenon, but its preparation is still complicated and expensive
[0020] Therefore, it would be desirable to have a simple material that is easy to prepare for the treatment of wounds, especially chronic wounds, that has good autolytic cleaning capabilities, ie allows optimized attachment of fibrin to reduce or eliminate the need for surgical procedures, without however detrimental affect the absorption and diffusion of exudate

Embodiment Construction

[0123] Preparation of materials according to the invention.

[0124] The following 3 materials according to the invention were prepared:

[0125] Ion exchange fibers used by Kaneka under the name Kanecaron Sold fibers in cation exchange fiber mode and molded them to 97g / m 2 nonwoven material. The negative charge density of the fibers constituting the nonwoven fabric was 1.5 mmol / g, and the liquid absorption capacity was 3 g of physiological saline per gram of fibers.

[0126] Ion exchange fibers used by Kaneka under the name Kanecaron Sold cation exchange fiber H-mode fibers and molded them to 109g / m 2 nonwoven material. These fibers had a negative charge density of 1.5 mmol / g and a fluid absorption capacity of 6.3 g of saline per gram of fiber.

[0127] Finally, Poseidon 3.3dtex / 40mm fiber sold by Kelheim in the form of a strand of non-converted fiber directly from the spinning process was used. These fibers had a negative charge density of 1.55 mmol / g and a fluid ab...

Abstract

The subject of the present invention is a material for wound healing, preferably for wound cleaning, comprising at least one electronegative fiber having a negative charge density of 0.01‑5 mmol / g and a liquid absorption capacity of less than 1 g Fiber 9.5g saline. Another subject of the invention is a medical device, such as a dressing or a bandage, comprising this material.

Description

technical field [0001] A subject of the present invention is a material comprising at least one electronegative fiber for wound healing, preferably for wound, especially chronic wound cleaning. Another subject of the invention is a medical device, such as a dressing or a bandage, comprising said material. Background technique [0002] A dressing is a protective device that covers a wound on the skin. Dressings can have several functions that may or may not be combined, such as: [0003] - protect the wound (from infection or irritation) and isolate it from the external environment; [0004] - Better healing by maintaining a beneficial moist environment in the wound bed; [0005] - Stop minimal bleeding by compressing small blood vessels; [0006] - to bring the wound edges together; [0007] - Absorbs exudate to prevent decay of wound edges and perilesional skin. [0008] Some types of dressings are therefore developed specifically to promote wound healing, while other...
