[0027] Figure 1 It is a structural schematic diagram of a medical gauze dressing described in the present application;
[0028] Among them: 1. Upper layer; 2. Middle layer; 3. Bottom layer. DETAILED DESCRIPTION
[0029] The following will clearly and completely describe the concept, specific structure and technical effects of the present application in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present application. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features created in this application can be combined interactively without conflicting with each other.
[0030] In order to solve the shortcomings of medical gauze dressings, such as low efficiency, long cycle, high cost, and low liquid absorption of products, the present application provides a medical gauze dressing, comprising an upper layer 1, a bottom layer 3, and an intermediate layer 2 arranged between the upper layer 1 and the bottom layer 3, wherein the material of the upper layer 1 and the bottom layer 3 is gauze, and the material of the intermediate layer 2 is spunlace non-woven fabric;
[0031] The middle layer 2 is formed by a single layer of spunlace nonwoven fabric or multiple layers of spunlace nonwoven fabric stacked together.
[0032] Specifically, the upper layer or the lower layer can be formed by stacking a single layer or multiple layers of gauze. The middle layer can be formed by using spunlace nonwoven fabric to replace half of the gauze, such as replacing two layers of gauze with one layer of spunlace nonwoven fabric, replacing four layers of gauze with two layers of spunlace nonwoven fabric, and replacing six layers of gauze with three layers of spunlace nonwoven fabric.
[0033] Therefore, by using gauze for the upper and lower layers and spunlace nonwoven fabric for the middle layer, the use of gauze can be reduced and the product cost can be reduced.
[0034] In a specific embodiment, the spunlace nonwoven fabric is any one of cotton fiber, viscose fiber, bamboo fiber, and PLA fiber. In the present application, by using spunlace nonwoven fabrics of different materials such as cotton fiber, viscose fiber, bamboo fiber, and PLA fiber, dressings with different characteristics can be provided to meet different medical needs. For example, cotton fiber has good safety and softness, viscose fiber and bamboo fiber provide better moisture absorption and comfort, and the use of PLA fiber can increase the composite mode, such as ultrasonic welding. Through the above technical solution, the problem of single material limitation can be solved, bringing more diversified product choices and better adaptability.
[0035] In a specific embodiment, the texture structure of the spunlace nonwoven fabric is any one of plain weave, mesh, and cut opening. In the present application, the different texture structures can affect the water absorption, air permeability and comfort of the dressing. The plain weave structure can provide better skin-friendliness, the mesh structure increases the water absorption area and improves the liquid absorption amount, and the cut opening can provide better softness. Through the above technical solution, the problem of single functionality of the dressing can be solved, bringing better liquid absorption effect and patient comfort.
[0036] In a specific embodiment, the mesh of the spunlace nonwoven fabric is realized according to any one of a spunlace jacquard process, a laser punching process, and a mechanical punching process. In the present application, the mesh structure realized by different punching processes can accurately control the water absorption and liquid distribution characteristics of the spunlace nonwoven fabric. The spunlace jacquard process, the laser punching process, and the mechanical punching process each have their own advantages. For example, laser punching can be very precise, while the spunlace jacquard process may be low in cost. Through the above technical solution, the problem of limitations of traditional manufacturing processes is solved, bringing higher manufacturing flexibility and product performance.
[0037] In a specific embodiment, the cut opening structure includes a crisscross shape, a cross shape, a circular hole shape, and a petal shape. In the present application, the different shapes of the cut openings can affect the liquid absorption and distribution efficiency of the dressing and increase the softness of the product. The crisscross and cross-shaped openings may provide multi-directional liquid transmission paths, and the circular hole shape and the petal shape may provide better aesthetics. Through the above technical solution, the problem of low liquid absorption efficiency of the dressing is solved, and the softness and aesthetics of the product are improved.
[0038] In a specific embodiment, the upper layer 1 and the middle layer 2 are sutured, and the middle layer 2 and the bottom layer 3 are sutured. In the present application, the suture connection provides a method for fixing the upper layer, the middle layer and the bottom layer to ensure the stability and durability of the dressing. Through the above technical solution, the problem of loose connection between the dressing layers can be solved, bringing better product durability and reliability.
[0039] In a specific embodiment, the suture track of the suture connection is any one of a "mouth"-shaped track, a "sun"-shaped track, a "mesh"-shaped track, and a "field"-shaped track. In the present application, different suture tracks can affect the fixing method and appearance of the dressing. For example, a "mouth"-shaped track may provide simple fixation, and a "sun"-shaped track may provide a more uniform tension distribution. Through the above technical solution, the problem of limitation of a single suture method can be solved, providing more design flexibility and product aesthetics.
[0040] In a specific embodiment, the upper layer 1 and the middle layer 2 are ultrasonically corrugated and welded, and the middle layer 2 and the bottom layer 3 are ultrasonically corrugated and welded. In the present application, ultrasonic corrugated welding is a connection method that does not require sutures, which can provide a 3D stereoscopic effect on the product, making it soft and comfortable to the touch, while improving product production efficiency. Through the above technical solution, the problems of low production efficiency and high labor costs of traditional suture methods can be solved.
[0041] In a specific embodiment, the yarn count of the upper layer 1 and the yarn count of the bottom layer 3 are any one of 18s, 21s, 24s, 32s, 36s, and 40s. The warp density × weft density of the upper layer 1 and the warp density × weft density of the bottom layer 3 are any one of 30*20, 19*15, and 26*18. The tensile strength of a single yarn (18s is 0.85N / strand, 21s is 0.75N / strand, 24s is 0.65N / strand, 32s is 0.5N / strand, 36s is 0.45N / strand, and 40s is 0.4N / strand)
[0042] Therefore, in the present application, by selecting different yarn counts, the thickness and strength of the dressing can be adjusted. A finer yarn count (such as 40s) can provide a softer touch, while a thicker yarn count (such as 18s) may provide higher strength; through the above technical solution, the problem of different requirements for dressing strength and softness in different application scenarios can be solved, and more diverse product options can be provided. Moreover, by adjusting the density of warp and weft yarns, the air permeability, water absorption and structural stability of the dressing can be changed; in the present application, different density combinations can adapt to different medical needs, such as denser weaving may provide better liquid absorption, while sparser weaving may provide better air permeability; through the above technical solution, the problem of single functionality of the dressing can be solved, bringing better adaptability and patient comfort.
[0043] Therefore, the medical gauze dressing has gauze on the upper and bottom layers and spunlace non-woven fabric in the middle layer, which can combine the advantages of gauze and spunlace non-woven fabric, retaining the advantages of gauze such as roughness, toughness, good air permeability and fast liquid absorption, while combining with spunlace non-woven fabric to increase the liquid absorption capacity of the dressing, reduce the use of gauze, reduce product costs and carbon emissions, comply with the dual carbon development goals, and meet the usage habits of doctors.
[0044] The above is a specific description of the preferred implementation of the present application, but the invention of the present application is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent modifications or substitutions without violating the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
