Problems solved by technology
[0003] Common clinical wound coverings include dressings such as gauze and cotton pads, but these wound coverings generally only have the function of covering the wound to reduce external infection, and cannot promote wound tissue regeneration, nor can it effectively improve the leakage of interstitial fluid. When treating wounds with high levels of exudate, the wound cover must be changed frequently, causing great burden and distress to the patient and caregivers

Embodiment Construction
[0028] The structure and effect of the present invention will be described in detail by citing the following embodiments in conjunction with the accompanying drawings.
[0029] First, if figure 1 As shown, in the first embodiment of the present invention, a wound cover 1 for covering a wound includes an absorbent body 10 and a plurality of rod-shaped activated carbon fibers 20 .
[0030] The absorber 10 is foamed from a polymer material and has a plurality of holes 12, such as Figure 6 , Figure 7 As shown, the polymer material may be, but not limited to, polyurethane resin (Polyurethane resin), polyvinyl ester resin (Poly(vinyl Alcohol) resin), ethylene-vinyl acetate resin (EVA resin) or a mixture thereof.
[0031] A plurality of activated carbon fibers 20 are dispersed in the absorber 10, and these activated carbon fibers 20 are partially exposed in the holes of the absorber 10 (such as Figure 6 , Figure 7 shown), wherein the diameter of these activated carbon fibers ...

Abstract
The invention relates to a wound dressing which is used for covering a wound. The wound dressing comprises at least one absorber and a plurality of rod-like active carbon fibers, wherein each absorber is made by foaming a high molecular material; each absorber is provided with a plurality of holes; the rod-like active carbon fibers are dispersed into at least one absorber; all the active carbon fibers are partially bulged in the holes of the absorbers; all the active carbon fibers are between 2 micrometers and 15 micrometers in diameter and are between 40 micrometers and 1500 micrometers in length. According to the wound dressing, interstitial fluid exuding from the wound can be absorbed by at least one absorber, and therefore, the wound is prevented from infiltration. The active carbon fibers in the at least one absorber can be used for radiating far infrared rays to promote the blood circulation near the wound, and further, the wound healing speed is accelerated.
Description
technical field [0001] The invention relates to a wound covering, in particular to a wound covering which has activated carbon fiber inside and can emit far infrared rays. Background technique [0002] The skin is the largest organ covering the surface of the human body, and it is the first line of defense to protect the human body from the invasion of foreign pathogens and external damage. In the case of a wound on the skin, in order to heal the wound smoothly, clinically, a wound cover is often used to cover the wound, so as to provide a better healing environment and avoid wound infection. [0003] Common clinical wound coverings include dressings such as gauze and cotton pads, but these wound coverings generally only have the function of covering the wound to reduce external infection, and cannot promote wound tissue regeneration, nor can it effectively improve the leakage of interstitial fluid. When treating wounds with high levels of exudate, the wound covering must b...
