Description

Technical Field

[0001] The utility model belongs to the technical field of non-woven fabrics, and in particular relates to an antibacterial medical non-woven fabric. Background Art

[0002] Non-woven fabric, also known as nonwoven fabric, is made by directional or random arrangement of fibers to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. In the medical field, it can be made into mats for beds and test tables. In order to protect the safety of patients and prevent cross infection, non-woven fabrics are required to have good antibacterial properties.

[0003] However, when the existing non-woven fabric is used as a mat, the part in contact with the human body absorbs body temperature and its temperature rises, causing the movement of the antibacterial agent molecules inside the non-woven fabric to intensify, accelerating the release rate of the antibacterial agent inside the non-woven fabric, thereby shortening the service life of the non-woven fabric.

[0004] Therefore, it is necessary to improve the nonwoven fabric in the prior art. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects in the prior art, provide an antibacterial medical non-woven fabric, and extend the service life of the medical non-woven fabric.

[0006] To achieve the above purpose, the specific technical scheme of the antibacterial medical nonwoven fabric of the utility model is as follows:

[0009] Preferably, in order to improve the uniformity of heat conduction of the temperature-averaging layer and expand the heat dissipation area, the temperature-averaging layer has a mesh structure and is evenly distributed between the top layer and the bottom layer.

[0010] Preferably, in order to allow the antibacterial agent molecules of the antibacterial layer to diffuse more toward the top layer and improve the antibacterial performance of the non-woven medical pad, the fiber density of the bottom layer is greater than the fiber density of the top layer.

[0011] Preferably, in order to protect the non-woven fabric when it is transported or used, an isolation layer is provided on the side of the bottom layer facing away from the top layer.

[0013] Preferably, in order to enhance the isolation effect of the isolation layer and reduce the loss of antibacterial molecules inside the non-woven fabric during transportation, the isolation layer is formed by polymerizing a plastic film and an aluminum foil.

[0014] Preferably, in order to improve the anti-slip performance of the non-woven medical pad, a plurality of anti-slip protrusions are evenly distributed on the side of the isolation layer away from the non-woven fabric body.

[0022] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] The terms "top surface", "bottom surface" and "underside" are based on the normal use state of the antibacterial medical non-woven fabric and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0024] like Figure 4 As shown, an antibacterial medical non-woven fabric comprises a non-woven fabric body 1, wherein the non-woven fabric body 1 comprises a top layer 101 and a bottom layer 102, wherein a temperature-averaging layer 104 and an antibacterial layer 103 are sandwiched between the top layer 101 and the bottom layer 102, and the antibacterial layer 103 is arranged on the top layer 101 and / or the bottom layer 102.

[0025] The above non-woven fabric can be used as a medical mat for a test bench or a hospital bed, and has a long-term and effective antibacterial effect. In the non-woven fabric, a silver ion antibacterial agent is sprayed on the opposite sides of the top layer 101 and the bottom layer 102, so that the silver ion antibacterial agent penetrates into the non-woven fabric fibers, and forms an antibacterial layer 103 after drying and solidification. When in use, the antibacterial agent molecules in the antibacterial layer 103 are slowly released to achieve a long-term antibacterial effect. The setting of the temperature-averaging layer 104 can conduct the heat from the higher temperature part of the non-woven fabric to all parts of the non-woven fabric, and then evenly dissipate it, thereby reducing the temperature of the non-woven fabric when in use, slowing down the release rate of the antibacterial agent molecules, and extending the service life of the medical mat made of the non-woven fabric.

[0026] Compared with the existing antibacterial non-woven fabric, the antibacterial layer 103 of the non-woven fabric is located between the top layer 101 and the bottom layer 102. When the antibacterial agent molecules are released, they need to pass through the top layer 101 or the bottom layer 102. The release rate of the antibacterial agent molecules is slowed down by the barrier of the top layer 101 and the bottom layer 102, and the antibacterial agent molecules are retained between the non-woven fabric fibers, thereby extending the effective antibacterial time of the non-woven medical pad while ensuring its antibacterial effect; and the setting of the temperature-averaging layer 104 can reduce the temperature of the non-woven medical pad and reduce the movement speed of the antibacterial agent molecules, thereby further slowing down the release rate of the antibacterial agent and reducing the ineffective loss of the antibacterial agent components, so as to extend the service life of the non-woven fabric.

[0027] A further improvement is that the temperature-averaging layer 104 is woven from heat-conducting fibers. The heat-conducting fibers can be woven from a mixture of metallic silver fibers and stainless steel fibers. The good thermal conductivity of metallic silver and stainless steel can greatly improve the thermal conductivity efficiency of the temperature-averaging layer 104, thereby achieving effective heat dissipation of the non-woven medical pad; the mixture of metallic silver fibers and stainless steel fibers can reduce costs, and metallic silver also has a certain antibacterial effect.

[0028] A further improvement is, Figure 4As shown, the temperature-averaging layer 104 is evenly distributed between the top layer 101 and the bottom layer 102 in a mesh structure. The mesh structure distribution can make the temperature-averaging layer 104 evenly distributed inside the non-woven fabric body 1, and expand the distribution range of the temperature-averaging layer 104, thereby expanding the heat dissipation range and heat dissipation uniformity of the temperature-averaging layer 104, and improving the cooling effect on the non-woven fabric.

[0029] A further improvement is that the fiber density of the bottom layer 102 is greater than the fiber density of the top layer 101. In the non-woven fabric, the bottom layer 102 with a greater fiber density produces a greater resistance to the diffusion of antimicrobial molecules, thereby allowing more antimicrobial molecules to diffuse toward the top layer 101. Since the top layer 101 is in contact with the patient when the non-woven medical pad is used, more antimicrobial molecules diffuse to the top layer 101, which can effectively ensure the antimicrobial effect of the non-woven medical pad and reduce the ineffective loss of the antimicrobial agent in the antimicrobial layer 103.

[0030] After the non-woven fabric is produced, it needs to be stored or transported. During this process, the antibacterial agent in the antibacterial layer 103 of the non-woven fabric is released, which will cause ineffective loss and affect the service life and antibacterial performance of the non-woven fabric.

[0031] In view of the above problems, further improvements made to nonwoven fabrics are as follows: Figure 4 As shown, the side of the bottom layer 102 facing away from the top layer 101 is provided with an isolation layer 2. The isolation layer 2 can isolate the non-woven fabric during storage and transportation, slow down the release of the antimicrobial agent and reduce the loss.

[0032] After the non-woven fabric is processed, it is usually wound on a winding drum. When the non-woven fabric is wound, the isolation layer 2 is located on the side away from the winding drum. In this way, after the non-woven fabric is wound layer by layer, the isolation layer 2 is located between the layers of the non-woven fabric, thereby separating the different layers of the non-woven fabric and preventing the antibacterial agent inside the antibacterial layer 103 from diffusing between different layers, resulting in uneven distribution of the antibacterial agent on the non-woven fabric, thereby ensuring the antibacterial performance of the non-woven fabric. After the non-woven fabric is wound, the isolation layer 2 is wrapped on the surface of the outermost layer of the non-woven fabric, which can cover the non-woven fabric, keep the non-woven fabric clean, reduce the loss of the antibacterial agent, and facilitate the transportation and storage of the non-woven fabric.

[0033] When the nonwoven fabric is cut into small pieces, the nonwoven fabric can be folded in half so that the isolation layer 2 is located on the outside of the folded nonwoven fabric, so that the isolation layer 2 can wrap the nonwoven fabric inside, thereby protecting the nonwoven fabric and facilitating the transportation and storage of the nonwoven fabric.

[0034] When the non-woven fabric is used as a medical pad, the isolation layer 2 can also play a waterproof role to prevent pollutants from penetrating into the bed through the non-woven fabric.

[0035] A further improvement is, Figure 1-3As shown, flanges are provided around the periphery of the isolation layer 2, and the positive projection of the non-woven fabric body 1 on the isolation layer 2 is located inside the flanges. Adhesive strips 201 are provided around the side of the flanges adjacent to the non-woven fabric body 1. The provision of the flanges can expand the coverage of the isolation layer 2 and enhance the protective effect of the isolation layer on the non-woven fabric; the adhesive strips 201 are easy-to-tear adhesive strips. When the non-woven fabric is wound or stored, the adhesive strips 201 can bond the flanges between adjacent layers together, thereby distributing the isolation layers 2 of different layers, so that the isolation layers 2 form a closed space. The non-woven fabric is in the closed space, which can enhance the protective effect of the non-woven fabric and reduce the probability of failure or damage during storage and transportation of the non-woven fabric.

[0036] A further improvement is, Figure 5 As shown, the isolation layer 2 is formed by the polymerization of a plastic film 203 and an aluminum foil 202. The aluminum foil 202 is connected to the bottom layer 102, and the plastic film 203 is located on the side of the aluminum foil 202 away from the bottom layer 102. The aluminum foil 202 can effectively isolate the non-woven fabric from oxygen, and play a role in moisture and light protection, which can effectively extend the validity period of the antibacterial agent in the antibacterial layer 103 and reduce the loss of the antibacterial agent, thereby extending the storage time of the non-woven fabric; the plastic film 203 is a polyethylene film, a polyvinyl chloride film or a polypropylene film. The setting of the plastic film 203 can achieve a protective effect on the aluminum foil 202 and reduce the probability of damage to the aluminum foil 202.

[0037] A further improvement is, Figure 5 As shown, the side of the isolation layer 2 facing away from the non-woven fabric body 1 is evenly distributed with a plurality of anti-skid protrusions 204. The anti-skid protrusions 204 are made of silicone material. After the non-woven fabric is made into a medical mat, the anti-skid protrusions 204 can play an anti-skid role, reduce the probability of the medical mat sliding on the test table or bed, and improve the convenience of using the medical mat.
