Description

Technical Field

[0001] This utility model relates to the field of medical gauze pad technology, and in particular to a medical gauze pad with edge anti-fraying. Background Technology

[0002] Medical gauze pads are widely used for emergency hemostasis, surgical absorption, and dressing care due to their low price, high absorbency, and good breathability.

[0003] However, when gauze is cut into individual pieces, the warp and weft yarns that have not been hemmed are exposed, especially cotton and viscose staple fibers. These fibers are easily pulled off during handling, unfolding, or repeated wiping, forming "cotton lint" or "lint" phenomena. Once the tiny gauze fragments that fall off enter the open wound, they may not only cause foreign body granulation and inflammatory reactions, but also migrate with the blood flow, increasing the risk of postoperative complications. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the edges of medical gauze sheets are prone to fraying after being cut in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a medical gauze sheet with anti-fraying edges, comprising a gauze layer, wherein the edge of the gauze layer is provided with a locking edge area, the locking edge area including a locking edge line and a microporous hot melt film, the microporous hot melt film having a U-shaped structure and being sleeved on the side of the gauze layer, the microporous hot melt film being assembled and connected to the gauze layer by the locking edge line, and the surface of the gauze layer being coated with an antibacterial layer.

[0006] In a preferred embodiment, the gauze layer is composed of 4-10 layers of pure cotton plain weave fabric, and is carboxymethylated to achieve a liquid absorption rate of ≥600%.

[0007] The microporous hot melt film has a porosity of 10%–25% and is bonded to the edge of the gauze layer by hot pressing at 130℃–150℃ and 0.3MPa–0.5MPa.

[0008] The antibacterial layer is deposited using an ultrasonic atomization spraying process, and the spraying point diameter of the antibacterial layer is no greater than 50 μm.

[0009] The locking line is embedded with a first color-developing wire and a second color-developing wire. The first color-developing wire and the second color-developing wire are respectively barium sulfate-containing X-ray imaging wire and magnetic resonance imaging wire. With the two types of color-developing wires, accurate detection can be achieved under both X-ray and magnetic resonance modes, avoiding residues during surgical use.

[0010] The gauze layer is sterilized by EO or γ-ray. The amount of lint shedding at the edge of the treated gauze layer is calculated according to USP. <881> The measured value is not more than 0.001 g / piece, and the edge tear strength is not less than 15 N as determined by ISO 13937-1.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention uses a microporous hot-melt film to heat-seal the gauze layer to the side, thus fixing the microporous hot-melt film and the edge of the gauze layer together. An additional locking line further secures it, and an antibacterial layer increases the antibacterial properties of the gauze layer. Attached Figure Description
