Problems solved by technology

However, this wound dressing focuses on the function of absorbing exudate, and the function of properly retaining exudate on the wound surface is insufficient
Further, it has been pointed out that prolonged direct contact of the skin with the hydrocolloid agent of the wound dressing can cause skin redness or rash

Embodiment Construction

[0063] The wound dressing of the present invention is a dressing that is pasted on a wound site, and can be applied to a method for treating wounds in a moist environment generated by exudate from the wound site. In the present invention, "wound" broadly refers to skin damage including burns, bedsores, sprains, cuts, abrasions, ulcers, surgical wounds, and the like.

[0064] Hereinafter, the structure of the wound dressing of the present invention will be described with reference to the drawings as necessary.

[0065] The wound dressing of the present invention is a wound dressing comprising at least three layers, the three layers sequentially comprising a first layer, a second layer and a third layer from the side for contacting the wound site, wherein the above-mentioned layers are laminated into One. The wound dressing of the present invention may be a wound dressing including a fourth layer in addition to the above-mentioned first layer, second layer, and third layer as nee...

Abstract

Provided is a further improved wound dressing suitable for a method for treating a wound while maintaining a moist environment created by exudate oozing from the wound. The wound dressing (5) comprises at least three layers including a first layer, a second layer and a third layer in order from the side used in contact with a wound site, which layers are integrally stacked together. The first layer (1) comprises a resin sheet material having a number of pores penetrating in a thickness direction. The second layer (2) comprises a sheet material of which the surface is water-repellent and becomes water-permeable when pressure is applied. The third layer (3) comprises a sheet material capable of absorbing and holding water. The wound dressing optionally comprises a fourth layer comprising a resin film, a fabric or a nonwoven.

Description

technical field [0001] The present invention relates to wound dressings suitable for use in the treatment of wounds such as burns, bedsores, sprains, cuts, abrasions and ulcers. Background technique [0002] In recent years, it has been confirmed that keeping the wound surface in a moist environment without drying it is effective for wound healing. In particular, since the components contained in the exudate from the wound site are useful for promoting wound healing, the method of treating the wound in a moist environment produced by the exudate from the wound site without disinfecting the wound (hereinafter may be referred to as known as "moist healing therapy") has been shown to be effective. Accordingly, various wound dressings have been developed suitable for this method of treatment. [0003] In order to effectively perform moist healing therapy, it is important to maintain a moderately moist environment on the wound surface through the exudate from the wound site. T...
