Embodiment Construction

[0041] Now refer to the attached Figures 1 to 2B , a wound dressing 1 comprising a water-absorbing member 4 and a wound contact layer 2 made of silk fibroin nanofibers having the above characteristics. The silk fibroin layer is in contact with the wound 7; in general, a part (usually the peripheral part) of the silk fibroin layer 2 will also be in contact with the skin 3 of the user.

[0042] Similarly, in Figure 2A In the wound dressing shown, the absorbent part is sandwiched between two layers of silk fibroin nanofibers. from Figure 2B It can be seen that such a device can be obtained simply by folding a device made of a silk fibroin layer and a water-absorbing layer; therefore, in this example, the layer of water-absorbing material is folded to provide An absorbent layer composed of layers joined together at one end.

[0043] The wound dressing 1 comprises a water-absorbing part 4, a wound contact layer 2 made of silk fibroin nanofibers having the characteristics des...

Abstract

A wound dressing device comprising at least one layer (2) of silk fibroin nanofibers and an absorbent component (4); the layer of fibroin nanofibers contacts the wound of the user and helps in the healing process.

Description

technical field [0001] The present invention relates to devices for wound dressings. More specifically, the present invention relates to devices for wound dressings comprising silk fibroin nanofibers. Background technique [0002] Several types of devices for wound dressings are known in the art. Simple dressings such as plaster are used for simple wounds, such as small cuts or bruises; some wounds, such as those caused by burns or diabetic ulcers, are chronic and their treatment is more complicated and often requires special wound dressings. The same is true for other wounds such as bedsores or pressure ulcers, open surgical wounds that do not heal in standard time even with sutures, or where a significant portion of skin and tissue has been lost. In this condition, the normal physiological healing process is usually blocked, and the wound does not scab over. For these wounds it is known in the art to provide special wound dressings which may contain drugs or substances ...
