Abstract
Provided is a dry pad, including a wound-covering membrane formed by arranging a fiber containing a hydrophilic polymer that is swollen by an exudate secreted from a wound, a hydrophobic polymer, and a dry wound-healing agent that is released through swelling of the hydrophilic polymer and is difficult to store in a liquid phase, and a first release member, which is a support on which the fiber is arranged and which is separated from the wound-covering membrane.
Claims14
A dry pad, comprising:
- a wound-covering membrane;
- and
- a first release member on which the wound-covering membrane is disposed, wherein the first release member is configured to be able to be separated from the wound-covering membrane,
- wherein the wound-covering membrane comprises:
- at least two layers of wound-covering membranes, the at least two layers of wound-covering membranes each being formed of electrospun fibers,
- wherein each of the electrospun fibers is made of a solution consisting of a hydrophilic polymer, a hydrophobic polymer, and a dry wound-healing agent, wherein the hydrophilic polymer is configured to be swollen by an exudate secreted from a wound of a user, and the dry wound-healing agent is configured to be released towards the wound through swelling of the hydrophilic polymer, and
- wherein, in the at least two layers of wound-covering membranes, a content of the hydrophilic polymer gradually increases towards the wound so as to achieve rapid swelling by the exudate.
