Description

Technical Field

[0001] This utility model belongs to the field of medical consumables technology, and in particular relates to an antibacterial medical pad. Background Technology

[0002] Medical drapes are medical and hygiene products commonly used in medical settings such as operating rooms, delivery rooms, and emergency rooms. Their primary function is to absorb blood, bodily fluids, and other secretions generated during surgery or childbirth, preventing infection and cross-infection. Medical drapes are characterized by excellent absorbency, sterility, and single-use properties, meeting the requirements for fluid absorption, protection, cleanliness, and sterility during surgery and treatment in the medical and hygiene field.

[0003] Medical drapes are generally made of absorbent, soft, and sterile pure cotton fibers, or disposable materials such as non-woven fabrics. Their antibacterial effect is short-lived, lacks active antibacterial function, and easily breeds bacteria, leading to cross-infection. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide an antibacterial medical pad, which effectively solves the problem of poor antibacterial properties.

[0005] The technical solution to the technical problem is as follows: it includes a surface layer, an intermediate layer, an absorbent layer and a bottom layer. The upper surface of the intermediate layer has multiple crisscrossing guide grooves, and multiple drainage holes are evenly arranged in the guide grooves. The drainage holes are connected to the absorbent layer from top to bottom. The intermediate layer has multiple slots evenly arranged, and antibacterial agents are placed in the slots. The antibacterial agents are adhered to the surface layer.

[0006] Preferably, the surface layer is a PLA nonwoven fabric with a weight of 40-60 g / m².

[0007] Preferably, the antibacterial agent is nano-silver.

[0008] Preferably, the absorbent layer is a mixture of superabsorbent resin and antibacterial fiber.

[0009] Preferably, the bottom layer is a waterproof and breathable membrane.

[0010] This invention has the following advantages over traditional equipment: 1) The combination of the guide channel and the drainage hole accelerates the diffusion of liquid to the absorbent layer and reduces bacterial retention; 2) The multi-layer structure design of the antibacterial agent combined with the surface layer, the absorbent layer being a highly absorbent antibacterial mixed layer and a waterproof bottom layer achieves active antibacterial, long antibacterial time, rapid liquid absorption and anti-permeability functions.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 3 An antibacterial medical pad is provided, comprising a top layer 1, a middle layer 2, an absorbent layer 3, and a bottom layer 4. The upper surface of the middle layer 2 has multiple crisscrossing drainage grooves 5, and multiple drainage holes 6 are evenly arranged in the drainage grooves 5. The drainage holes 6 are connected to the absorbent layer 3 vertically. The middle layer 2 has multiple evenly arranged slots 7, and antibacterial agents 8 are placed in the slots 7. The antibacterial agents 8 are adhered to the top layer 1.

[0017] The surface layer 1 is a PLA nonwoven fabric with a weight of 40-60 g / m².

[0018] The antibacterial agent 8 is nano-silver.

[0019] The absorbent layer 3 is a mixture of highly absorbent resin and antibacterial fiber.

[0020] The bottom layer 4 is a waterproof and breathable membrane.

[0021] In use, the edges of the pad are ultrasonically sealed, and the pad has detachable medical adhesive tape on both sides for easy pasting and fixing. The middle layer 2 is made of bamboo charcoal fiber, which is moisture-wicking, breathable, and antibacterial. The layers are bonded together with hot melt adhesive. The surface layer 1 completely covers the upper surface of the middle layer 2. When the patient uses the pad, the surface layer 1 comes into contact with the patient. The surface layer 1 is non-woven fabric, and the antibacterial agent 8 is nano-silver. The nano-silver is bonded to the non-woven fabric. According to GB / T 20944.3 standard, the antibacterial rate against Staphylococcus aureus and Escherichia coli is ≥99%, showing good antibacterial effect. The fluid produced by the patient enters the middle layer 2 through the surface layer 1. The upper surface of the middle layer 2 has multiple crisscrossing drainage channels 5, and multiple drainage holes 6 are evenly arranged in the drainage channels 5 to accelerate the flow of fluid through the drainage channels 5 and drainage holes 6 into the absorbent layer 3, reducing the amount of bacteria retained in the surface layer 1. The absorbent layer 3 fully absorbs the fluid.

[0022] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
