Abstract

The invention belongs to the technical field of medical functional dressings, and discloses a hydrogel cold application. The hydrogel cold application comprises a dressing layer, a gel layer and an adhesive layer which are sequentially arranged, wherein the dressing layer and the gel layer are tightly bonded, the gel layer is of an n-shaped structure, the vacant part of the gel layer is filled with the dressing layer, and the cross sections of the gel layer and the dressing layer are rectangular, square or circular. The product disclosed by the invention is reasonable in structural design, thecontained functional materials can be fully combined with the swelling and pain relieving effects of the dressing layer and the gel layer, the cold application effect of the gel layer is greatly improved, and the product is suitable for nursing wound patients and relieving pain of the wound patients, can also be suitable for fever abatement of fever patients, and can be popularized and used in families.

Description

technical field [0001] The invention relates to the technical field of functional dressings for medical devices, in particular to a hydrogel cold compress. Background technique [0002] Hydrogels are gels in which water is the dispersion medium. Medical hydrogel is developed based on the theory of "moist therapy" for wound care. It has the characteristics of large drug loading, good transdermal effect, controllable quality, good air permeability, and low skin irritation, making it an ideal transdermal gel. drug delivery vehicle. The hydrogel cold compress is a gel that is attached to the skin. The temperature of the skin on the body surface is transmitted to the cold gel, and the heat is absorbed by the water molecules in the gel. A large amount of heat is taken away by the evaporation of water, which can quickly lower the body surface. The local temperature of the skin can reduce the burning sensation, pain and sensitivity of the local skin, so as to achieve the effect of...
