Embodiment 1

[0025] A zipper-type medical dressing with electret, which is composed of a protective layer 1, a silicone gel layer 2, a liquid-absorbing layer 3, and a zipper layer 5, which are tightly bonded from bottom to top; the silicone gel layer 2 A hollow three-dimensional cavity is formed between the zipper layer 5, and the liquid-absorbing layer 3 is located in the hollow three-dimensional cavity. The liquid-absorbing layer 3 can be replaced or removed at will, and the inner surfaces of the two sides of the zipper layer 5 are respectively An electret thin film layer 4 is compounded.

[0026] The zipper layer 5 is composed of two pull straps, a pull head, a pull piece, and two fastener elements. The two drawstrings are made of highly breathable polyurethane film, and a single row of small holes are set on both sides of the two drawstrings. The inner surfaces of the two drawstrings are respectively compounded with electret film layers 4 . The zipper layer 5 is combined with the sil...

Abstract

The invention provides a zipper-type medical dressing provided with an electret. The medical dressing is constituted by closely sticking a protective layer, a silicone gel layer, a liquid-absorbent layer and a zipper layer sequentially from bottom to top, wherein a three-dimensional hollow cavity is defined between the silicone gel layer and the zipper layer; the liquid-absorbent layer is arrangedin the three-dimensional hollow cavity; and the liquid-absorbent layer can be optionally replaced or detached. According to the medical dressing provided by the invention, different functions are provided in accordance with the demands in various healing periods of a wound surface, so that the healing of the wound surface is promoted. The medical dressing provided by the invention has an electreteffect, and moreover, the medical dressing is excellent in liquid-absorbing performance, antibacterial property, scar removal performance and air permeability; and the medical dressing can take an obvious effect on treating chronic wounds.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a zipper type medical dressing with an electret. Background technique [0002] Zipper is a daily necessities that people are very familiar with. The slide fastener has two zipper tapes. The two zipper tapes are fixed with fastener elements at the edges of the opposite sides (that is, the inner side). Zippers are generally used on clothing, shoes, leather bags and boxes, and have the advantages of convenient use and reliable opening and closing. [0003] In terms of medical use, it is currently mainly used as a seam-free tape for suturing wounds to reduce the pain of patients during suturing. As a medical dressing, wound care, there is no report. [0004] Skin tissue is a type of bioelectret that can store electrical charge or maintain a polarized state for a long time. The exogenous electret can provide the skin with an electrostatic field and a microcurr...
