Problems solved by technology

Nowadays, the market value of medical dressings is becoming more and more important, but the shortcomings of existing medical dressings are also very prominent: such as poor waterproof performance of dressings, once water enters, dressings need to be replaced, and frequent dressing changes are not conducive to wound healing The ventilation effect is not good, so that the comfort is not high; the amount of drug layer soaked in the drug layer is small, and the dressing needs to be replaced frequently; Tight, painful when changing dressings and can damage new tissue in severe cases

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] see Figure 1-4 , a medical composite dressing of the present invention, comprising a waterproof layer 1, a breathable layer 2, an antibacterial layer 4, a drug layer 6 and an adhesive layer 7 arranged in sequence from bottom to top.

[0023] The edge of the waterproof layer 1 is integrally connected with a wing part 11, and the waterproof layer 1 is composed of a plastic film, which can be selected from water-based polyurethane, polyethylene, polylactic acid or polycarbonate, and the waterproof layer 1 is translucent. The translucent waterproof layer 1 facilitates direct observation of the absorption and seepage of the dressing. The material of the fin portion 11...

Abstract

The invention relates to a medical composite dressing. The medical composite dressing comprises a waterproof layer, a breathable layer, an antimicrobial layer, a drug layer and an adhesive layer, and the waterproof layer, the breathable layer, the antimicrobial layer, the drug layer and the adhesive layer are arranged from bottom to top in sequence, wherein a wing sheet part is integrally connected to the edge of the waterproof layer, the wing sheet part is generally semicircular, the antimicrobial layer comprises fabric and nanometer particles distributed in the fabric, the drug layer is constituted by a nanofiber layer and has a honeycomb surface, honeycomb holes are formed in the surface of the honeycomb surface, the surfaces of the honeycomb holes are coated with hydrophobic layers, and the adhesive layer is distributed in a latticed shape. The medical composite dressing is reasonable in structural design, resistant to water and breathable, the antimicrobial effect is good, the drug leaching amount is high, and the replacement is convenient.

Description

technical field [0001] The invention relates to the field of medical material fabric structure, in particular to a medical composite dressing. Background technique [0002] As a covering for wounds, medical dressings can replace damaged skin to act as a temporary barrier during wound healing, avoid or control wound infection, and provide an environment conducive to wound healing. Nowadays, the market value of medical dressings is becoming more and more important, but the shortcomings of existing medical dressings are also very prominent: such as poor waterproof performance of dressings, once water enters, dressings need to be replaced, and frequent dressing changes are not conducive to wound healing The ventilation effect is not good, so that the comfort is not high; the amount of drug layer soaked in the drug layer is small, and the dressing needs to be replaced frequently; Tight, causing pain when changing the dressing and in severe cases can damage the new tissue. Cont...
