Hydrogel with continuous antibacterial ability

Abstract

The invention discloses hydrogel with continuous antibacterial ability. The hydrogel is prepared from a zinc-containing organic matter, a gel matrix and water. The hydrogel has the advantages that: antibacterial substances in the hydrogel can emit electromagnetic waves with certain wavelength and frequency, the electromagnetic waves destroy DNA, cell membranes and other structures of bacteria, andtherefore the effects of sterilization and bacteriostasis are achieved, consumption caused by the antibacterial effect in the antibacterial process is avoided, and the hydrogel is not absorbed by thehuman body, therefore, a protective film can be formed on the surface of skin or a wound surface after the hydrogel is used, and invasion against external bacteria is avoided. The hydrogel provided by the invention has bactericidal and bacteriostatic effects, especially can effectively treat and prevent infection after being used on skin or a wound surface, and can further promote wound surface healing through a moisturizing effect.

Description

Technical field[0001]This application relates to the technical field of medical devices, in particular to a hydrogel with sustained antibacterial ability.Background technique[0002]Hydrogel is a hydrophilic network polymer swelling body that can swell in water, absorb and retain a large amount of water without dissolving in water. It has a smooth surface and good biocompatibility. It is used in the fields of biology and medical engineering. Has been extensively researched and applied. Due to the low liquid absorption, traditional dressings need to be thickly bandaged and replaced frequently. The dressings are easy to dry after absorbing liquid and adhere to the wound, causing secondary trauma. Dressings made of hydrogel can accelerate wound healing and are easy to replace. The wound has no advantages such as residual dressings, and it is gradually replacing traditional dressings.[0003]Although the existing hydrogel products can promote wound healing, they are prone to infection; some...

Problems solved by technology

[0003] Although the existing hydrogel products can promote wound healing, they are prone to infection; some hydrogel products with antibacterial function, such as Prandtl, are antibacterial, but they do not have long-term effect and cannot form on the skin or wound surface. A long-lasting antibacterial protective layer, and the chemical antibacterial mechanism is the main mode of action, which will inevitably produce certain biological toxicity
