Is mainly used for treating small wounds and has the effects of quickly stopping bleeding, protecting wound surfaces and preventing infection. However, these functions are not ideal, for example, the existing wound dressings have no pleasant smell, some have even peculiar smell, and thus have adverse effects on the wounded.
In recent years, attention has been paid to the medical effects of aromatic plant essential oils such as forest bath, aromatherapy, and phytoncide. With the intensive research on the fragrance, people find that the fragrance has the effects of relaxing nervous mood, relieving stress, stimulating people and the like. For example, vanilla, clove, lavender, peppermint, turpentine, etc. have sedative effect, whereas chamomile and lavender have bactericidal effect.
In addition, the common adhesive bandage only consists of an adhesive tape, a water absorption layer and an isolation layer, functional components are not contained in the product structure, so that the common adhesive bandage has no sterilization effect, although a plurality of nano-silver antibacterial adhesive bandages exist at present, nano-silver is easy to lose, Chinese patent CN200920117403.9 designs a nano-silver antibacterial adhesive bandage, the method is to coat or permeate nano-silver or a nano-silver compound containing silver ions on a middle base layer, a medical net film is covered on the upper surface of the nano-silver antibacterial adhesive bandage, the medical net film serves as a barrier to prevent the nano-silver from losing, but only coating and permeating cannot enable the nano-silver to be firmly combined with the middle base layer, and even if one layer of the medical net film is covered, the nano-silver particles cannot be guaranteed not to lose.
