Description

Technical Field

[0001] This utility model relates to the field of medical textile materials technology, specifically a waterproof and breathable composite conductive medical elastic fabric. Background Technology

[0002] In the medical field, medical elastic fabrics are widely used, often for bandaging, fixing medical devices, and assisting in treatment. However, most existing medical elastic fabrics have limited functions; for example, ordinary elastic fabrics only possess elasticity, making it difficult to meet the diverse needs of complex medical environments, such as waterproofing, breathability, and conductivity.

[0003] Some waterproof elastic fabrics often have poor breathability, which can easily lead to damp and stuffy skin for patients after prolonged use, causing discomfort and even skin problems. On the other hand, some conductive medical fabrics have poor elasticity and protective properties, and are prone to deformation or damage during use, making it impossible to reliably provide conductive signal transmission for medical devices. In addition, the existing medical elastic fabrics lack sufficient synergy between functional layers in their structural design, making it difficult to achieve efficient integration of multiple functions.

[0004] Therefore, there is an urgent need for a medical elastic fabric that can simultaneously provide waterproofing, breathability, conductivity, and good elasticity and protective properties to meet the diverse needs of modern medicine. In view of this, we propose a waterproof, breathable, composite conductive medical elastic fabric. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waterproof and breathable composite conductive medical elastic fabric.

[0006] The technical solution of this utility model is: A waterproof, breathable, composite conductive medical elastic fabric comprises, in sequence, a surface layer, a protective outer layer, a waterproof and breathable membrane, a three-layer elastic fabric base layer, an antistatic layer, a moisture-absorbing layer, and a skin-friendly inner layer. The surface layer features transverse and longitudinal elastic ribs, a design that significantly enhances the overall elasticity and resilience of the fabric, allowing it to better conform to the contours of different parts of the body and adapt to deformation during movement, providing a comfortable and secure fit for the patient. The three-layer elastic fabric base layer consists of a first elastic layer, a second elastic layer, and a third elastic layer, in sequence. The second elastic layer is interconnected with the first and third elastic layers via spaced elastic connecting ribs, creating a unique elastic structure that not only further enhances the overall elasticity but also strengthens the structural stability of the base layer, ensuring it is not easily deformed during long-term use and stretching. The third elastic layer is tightly bonded to the waterproof and breathable membrane, effectively ensuring the stability of the membrane. At the same time, thanks to the properties of the waterproof and breathable membrane, the fabric has excellent waterproof performance, which can block the intrusion of external liquids and ensure that sweat and other moisture on the skin surface can be discharged in time, keeping the skin dry and creating a good environment for wound healing.

[0007] As a preferred technical solution, the thickness of the skin-friendly inner layer is two-thirds of the thickness of the first elastic layer, and the surface has a fine velvety structure. This structure can increase the contact area with the skin, improve skin-friendliness and comfort, and reduce friction on the skin.

[0008] As a preferred technical solution, the moisture-absorbing layer has a moisture-guiding microporous structure on the side near the antistatic layer, and the moisture-absorbing layer and the antistatic layer have the same thickness. The moisture-guiding microporous structure can accelerate the conduction of sweat, allowing sweat to quickly pass through the moisture-absorbing layer and preventing the skin surface from becoming damp.

[0009] As a preferred technical solution, the antistatic layer has an interlaced conductive network and the conductive fibers are distributed in three dimensions, which can more efficiently discharge static electricity and ensure stable conductivity in different directions, thus meeting the signal transmission requirements of medical devices.

[0010] As a preferred technical solution, the three layers of elastic fabric base layer together form an elastic support sandwich structure; wherein the first elastic layer, the second elastic layer and the third elastic layer form a parallel and spaced layered structure, and adjacent layers are connected by evenly distributed elastic connecting ribs, which are arranged in a matrix on the plane, and the diameter of the elastic connecting ribs is one-fifth of the distance between adjacent layers; when the elastic support sandwich structure is subjected to force, each layer can move slightly relative to the others, and the deformation of the elastic connecting ribs buffers the external force while maintaining the stability of the overall structure, so that the elastic fabric can better adapt to various human activities.

[0011] As a preferred technical solution, the protective outer layer surface is provided with a diamond-shaped anti-slip texture; the diamond-shaped anti-slip texture is distributed in a regular array; adjacent diamonds are connected by raised dividing lines; the diamond-shaped anti-slip texture makes the protective outer layer surface form a concave-convex structure, increasing the friction when in contact with the outside, and preventing slippage during wrapping or fixing.

[0012] As a preferred technical solution, the surface layer is embedded with a mesh-like elastic rib structure; the mesh-like elastic rib is composed of transverse elastic ribs and longitudinal elastic ribs that intersect each other perpendicularly, which can significantly enhance the tear resistance and abrasion resistance of the surface layer and extend the service life of the elastic fabric.

[0013] As a preferred technical solution, the waterproof and breathable membrane is tightly bonded to the three-layer elastic fabric base layer; the edges of the waterproof and breathable membrane are folded inward and wrapped around the sides of the three-layer elastic fabric base layer, and a wavy bonding surface is provided at the bonding point between the waterproof and breathable membrane and the three-layer elastic fabric base layer. The wavy bonding surface increases the contact area between the two and effectively improves the sealing performance of the waterproof and breathable barrier.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses an elastic support sandwich structure composed of three layers of elastic fabric base and elastic connecting ribs, which enables the elastic fabric to effectively buffer external forces while having high elasticity, improve structural stability, and adapt to complex human activities. Compared with traditional single-structure elastic fabric, it is more practical.

[0015] 2. This utility model features a transverse elastic rib, a longitudinal elastic rib, and a grid-like elastic rib structure on the surface layer, and a diamond-shaped anti-slip texture on the protective outer layer, which enhances the wear resistance and anti-slip performance of the elastic fabric, extends its service life, and improves its reliability during use.

[0016] 3. This utility model utilizes the unique structural design of the waterproof and breathable membrane, as well as the moisture-wicking microporous structure of the moisture-absorbing layer, to achieve efficient waterproof and breathable functions. At the same time, the three-dimensional conductive network of the antistatic layer ensures stable conductivity. The synergistic effect of multiple functions meets the diverse needs of modern medical care. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please refer to the accompanying drawings. This utility model provides a technical solution: like Figures 1-4As shown, a waterproof and breathable composite conductive medical elastic fabric comprises, from the outside to the inside, a surface layer 100, a protective outer layer 200, a waterproof and breathable membrane 300, a three-layer elastic fabric base layer 400, an antistatic layer 500, a moisture-absorbing layer 600, and a skin-friendly inner layer 700. In the three-layer elastic fabric base layer 400, the first elastic layer 401, the second elastic layer 402, and the third elastic layer 403 are parallel and spaced apart. The second elastic layer 402 is connected to the first elastic layer 401 and the third elastic layer 403 by evenly spaced, matrix-arranged elastic connecting ribs. When the elastic fabric is subjected to force due to human movement, the layers can move slightly relative to each other, the elastic connecting ribs deform, buffering the external force, maintaining the overall structural stability of the elastic fabric, and ensuring that the elastic fabric fits tightly against the human body. The third elastic layer 403 is tightly bonded to the waterproof and breathable membrane 300. The edges of the waterproof and breathable membrane 300 are folded inward to wrap around the sides of the three-layer elastic fabric base layer 400. The wavy bonding surface increases the contact area, effectively blocking external moisture from entering, while allowing internal water vapor to pass through.

[0019] like Figure 2 As shown, in a preferred embodiment, the transverse elastic ribs 101 and longitudinal elastic ribs 102 inside the surface layer 100 are interwoven perpendicularly to each other, providing basic elasticity to the surface layer 100. Simultaneously, the mesh-like elastic ribs extend through the thickness direction of the surface layer 100, interwoven with the elastic ribs, enhancing the tear resistance of the surface layer 100. The diamond-shaped anti-slip texture on the surface of the protective outer layer 200 is distributed in a regular array, with raised dividing lines separating the diamonds. When used for wrapping or fixing, the uneven diamond-shaped anti-slip texture increases friction with external objects, preventing slippage. The waterproof and breathable membrane 300 is microporous.

[0020] like Figure 2 As shown in the preferred embodiment, within the antistatic layer 500, conductive fibers composed of carbon fiber and silver ion composite fibers are distributed in a three-dimensional interlaced pattern to form a conductive network, effectively dissipating static electricity generated by the fabric. In specific areas connected to medical devices, the proportion of silver ion composite fibers is increased, forming a ring-shaped conductive trajectory to ensure stable conductivity. The moisture-wicking layer 600, with its moisture-wicking microporous structure near the antistatic layer 500, can quickly absorb sweat conducted from the skin-friendly inner layer 700 and conduct it to the outer layer, keeping the skin dry. The dense, velvety structure of the skin-friendly inner layer 700 makes full contact with the skin, reducing friction. Its thickness is a certain proportion of the thickness of the first elastic layer 401, ensuring softness while providing a comfortable user experience in conjunction with other layers. This utility model of waterproof and breathable composite conductive medical elastic fabric involves attaching the skin-friendly inner layer 700 to the patient's skin for bandaging or securing medical devices as needed. During human activity, the elastic support structure of the three-layer elastic fabric base layer 400 adapts to the body's stretching and bending. When in contact with the external environment, the anti-slip texture of the protective outer layer 200 prevents slippage, and the surface layer 100 resists abrasion. When connecting to medical monitoring equipment, the conductive network of the antistatic layer 500 stably transmits signals. Throughout the process, the waterproof and breathable membrane 300 and the moisture-absorbing layer 600 work together to maintain a dry and comfortable environment for the skin.
