Description

Technical Field

[0001] This utility model relates to a medical consumable, specifically, to a composite medical cotton gauze pad. Background Technology

[0002] Medical gauze pads are white, soft, odorless, tasteless, highly absorbent, and detectable. They are mainly used in medical facilities to absorb tissue exudate and body fluids. Medical gauze pads are available in different types, such as: Type A with X-ray detectable barium strips (films) and tape; Type B without X-ray detectable barium strips (films) and tape; Type C without X-ray detectable barium strips (films) and tape; and Type D with X-ray detectable barium strips (films) and tape, etc.

[0003] To improve the practical performance of medical gauze pads, a series of improvements have been made to their structure. For example, Chinese patent CN217960515U discloses a novel sterile and breathable gauze pad, and Chinese patent CN218739339U discloses a medical degreased cotton gauze pad. However, most of these solutions focus on improving the absorbency of the medical gauze pads and do not take into account the needs of bandaging and applying medication.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a composite medical cotton gauze pad.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A composite medical cotton gauze pad includes a base layer and an absorbent layer disposed on the upper side of the base layer. A shallow groove is provided in the middle of the absorbent layer, and a hemostatic layer is disposed in the shallow groove. The hemostatic layer protrudes from the absorbent layer. Release paper is covered on the upper side of the absorbent layer, and the release paper completely covers the hemostatic layer. A fixing element is provided on the lower side of the base layer or the edge of the absorbent layer.

[0007] The base layer is a waterproof and breathable layer, which includes two layers of PP spunbond nonwoven fabric and a PE polymer breathable membrane placed between the two layers of PP spunbond nonwoven fabric.

[0008] The absorbent layer is formed by folding or sewing 20-30 layers of gauze, and the edges of the absorbent layer and the shallow groove are sealed with overlock or heat-pressed edges.

[0009] The edge of the absorbent layer is formed by folding or sewing 25-30 layers of gauze, while the shallow groove is formed by folding or sewing 20-24 layers of gauze.

[0010] The absorbent layer is made of a blend of high-density cotton yarn and highly absorbent fibers; the highly absorbent fibers are one or a combination of at least two of the following: chitosan fibers, synthetic polymer fibers, modified cellulose fibers, and alginate fibers.

[0011] The hemostatic layer comprises a drug-loaded nanofilm and a hemostatic drug loaded on the drug-loaded nanofilm. The hemostatic layer and the absorbent layer are hot-pressed together.

[0012] The base layer is connected to a fixing strap on the lower side, and an adhesive layer and release paper are provided on one side of the fixing strap.

[0013] An adhesive layer is provided at the edge of the absorbent layer, and the release paper includes symmetrically arranged covering blocks. One side of each covering block is connected to the adhesive layer, and the other side of the two covering blocks overlaps and covers the surface of the hemostatic layer.

[0014] Compared to existing technologies, the advantages of this invention are as follows: This invention provides a composite medical cotton gauze pad with scientific design, convenient use, and good hemostatic effect, making it convenient for application in the process of stopping bleeding and applying medication to external injuries. Specifically, the base layer is a waterproof and breathable layer, which is waterproof while also having a certain degree of breathability, improving patient comfort. An absorbent layer is set on the base layer to absorb body fluids from the wound in a timely manner. A shallow groove is set in the middle of the absorbent layer, and a hemostatic layer is set in the shallow groove. The hemostatic layer is slightly protruding to facilitate full contact of the wound with the hemostatic agent. Attached Figure Description
