Description

Technical Field

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

[0002] Medical nursing pads are disposable hygiene products used on hospital beds or examination beds. They are used for cleaning bedridden patients or preventing bedsores, and can be used for local care of the application area (surface skin or mucous membranes). Most existing medical nursing pads use a multi-layer absorbent structure, but they have the following problems: the bottom layer of traditional nursing pads is mostly made of completely waterproof material, which can easily lead to skin dampness and bacterial growth with long-term use, and has poor breathability; the absorbent layer design is unreasonable, and liquid can easily accumulate locally, reducing breathability and increasing the risk of skin irritation. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a breathable medical care pad that effectively solves the problem of poor breathability.

[0004] The technical solution to the technical problem is as follows: it includes a surface layer, on which multiple air vents are evenly distributed. Below the surface layer, a flow guiding layer, an absorption layer, and a bottom layer are arranged in sequence. Multiple polygonal blocks are evenly fixed on the upper surface of the flow guiding layer, and flow guiding channels are formed between the multiple polygonal blocks. The flow guiding layer is provided with flow guiding holes that are vertically connected to the flow guiding channels. The absorption layer has an S-shaped wave structure.

[0005] Preferably, the surface layer is made of skin-friendly non-woven fabric, and the surface of the surface layer has a plurality of breathable pores evenly distributed thereon. The pore diameter of the breathable pores is 0.1-0.5mm and the porosity is ≥30%.

[0006] Preferably, the absorbent layer is a composite layer of fluffy cotton and superabsorbent polymer, with a thickness of 3-5 mm.

[0007] Preferably, the height of the polygonal block is 1-2 mm, and the diameter of the guide hole 7 is 0.8-1 mm.

[0008] Preferably, the surface edge is provided with a leak-proof baffle, the height of which is 5-8mm, and the interior is filled with absorbent fibers.

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

[0010] This invention has the following advantages over traditional equipment: 1) The surface micropores and the bottom waterproof and breathable layer have a two-way breathable structure, which has a good breathability effect; 2) The polygonal blocks guide the liquid to diffuse in all directions, avoiding local dampness and providing good comfort. The absorbent layer has an S-shaped wave structure, which is ingenious and adapts to the body's curves. Attached Figure Description

[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 A breathable medical care pad is provided, comprising a surface layer 1, on which multiple breathable holes are evenly distributed. Below the surface layer 1, a flow guiding layer 2, an absorbent layer 3, and a bottom layer 4 are arranged in sequence. Multiple polygonal blocks 5 are evenly fixed on the upper surface of the flow guiding layer 2, and flow guiding channels 6 are formed between the multiple polygonal blocks 5. The flow guiding layer 2 is provided with flow guiding holes 7 that are vertically connected to the flow guiding channels 6. The absorbent layer 3 has an S-shaped wave structure.

[0017] The surface layer 1 is made of skin-friendly non-woven fabric. Multiple breathable pores are evenly distributed on the surface of the surface layer 1. The pore diameter of the breathable pores is 0.1-0.5mm and the porosity is ≥30%.

[0018] The absorbent layer 3 is a composite layer of fluffy cotton and superabsorbent polymer, with a thickness of 3-5 mm.

[0019] The polygonal block 5 has a height of 1-2 mm, and the diameter of the guide hole 7 is 0.8-1 mm.

[0020] To prevent liquid from flowing out, the surface layer 1 is provided with a leak-proof baffle 8, which is 5-8mm high and filled with absorbent fibers.

[0021] The bottom layer 4 is a waterproof and breathable layer.

[0022] In use, each layer of this invention is composited by ultrasonic welding. The outer surface of the bottom layer 4 is coated with an antibacterial coating, providing excellent antibacterial effects. The bottom layer 4 is laid on the hospital bed, with the top layer 1 in contact with the patient. The top layer 1 is made of skin-friendly non-woven fabric. Liquid from the patient enters the drainage layer 2 through multiple breathable holes. Liquid in the drainage channel 6 enters the absorption layer 3 through the drainage holes 7. The absorption layer 3 is made of a mixture of wood pulp cotton and sodium polyacrylate (ratio 7:3), hot-pressed into an S-shaped wave structure. The elastic compression rate of the absorption layer 3 is ≥40%, adapting to the body's curves. The absorption layer 3 absorbs liquid, with uniform liquid diffusion and good absorption effect. The patient experiences high comfort when in contact with the top layer 1, reducing the risk of bedsores and skin infections. The bottom layer 4 is a waterproof and breathable layer to prevent liquid leakage onto the hospital bed, making it convenient to use.

[0023] 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.
