Embodiment Construction

[0040] Please refer to Figure 1A with Figure 1B , Figure 1A is a schematic diagram illustrating a wound dressing 100 according to an embodiment of the present invention, Figure 1B It is a photo of a wound dressing 100 according to an embodiment of the present invention.

[0041] The wound dressing 100 proposed in the embodiment of the present invention mainly includes fibers formed of alginate, and the breaking strength of the wound dressing 100 is improved by virtue of the length of the fibers and the arrangement of the fibers, so as to avoid the traditional When the non-woven alginate wound dressing is removed from the wound, it may break or stick to the wound to form fluff.

[0042] Here, the breaking strength refers to the force applied to the wound dressing when the wound dressing breaks, and the unit used is kilogram force (kgf). In the following examples, the breaking strength of the wound dressing 100 is measured using the American Society for Testing and Materia...

Abstract

The invention relates to an alginate wound dressing as well as a manufacture method and a manufacture device of the alginate wound dressing. The wound dressing comprises a first fiber layer and a second fiber layer, wherein the first fiber layer consists of a plurality of mutually bonded first fibers, the second fiber layer consists of a plurality of mutually bonded second fibers, and the first fibers and the second fibers are made of alginate. The first fibers are parallel and extends in a direction approximately parallel to the first direction, the second fibers are parallel and extends in a direction approximately parallel to the second direction, the first direction is not parallel to the second direction, the second fiber layer is stacked on the first fiber layer, and in addition, the second fibers are bonded with the first fibers. The length of the first fibers and the second fibers is proper, so the fracture strength of the wound dressing is greater than about 1.5 kilogram force.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200910265956.3 and the invention title "alginate wound dressing, its manufacturing method and its manufacturing device" submitted by the applicant on December 21, 2009. technical field [0002] The present invention relates to a wound dressing, and in particular to an alginate wound dressing. Background technique [0003] In the past, when dealing with wounds, it is generally believed that keeping the wound dry can provide a better environment for wound healing and make the wound heal more easily. Therefore, in traditional treatment methods, gauze is mainly used to prevent the wound from being infected by dirt in the external environment, and even to keep the wound dry and clean. However, in this therapy, the wound and the wound dressing often stick together, causing the wound to stick to the newly healed wound when the wound dressing is removed, causing second...
