Electronic wound plaster

Technical Field

Background

Currently, when a wound occurs on the skin surface, bacteria on the wound form a bacterial biofilm after aggregation. New Atlas networks report that up to 80% of bacterial infections are caused by this surface organism known as bacterial biofilms, which are mainly composed of viscous substances consisting of bacterial DNA, polysaccharides and proteins, usually produced around wounds or implanted medical devices, such as catheters, tracheostomy tubes, or dressing not replaced.

The treatment of wounds is usually done by applying antibiotics and covering them with bandages, which is cumbersome and inconvenient to use. However, with the extensive use of antibiotics in the medical field, many bacteria have evolved resistance to drugs, and the effects of conventional antibiotics are increasingly poor in terms of disinfection and anti-inflammation, and wound infection resistance becomes more challenging.

The biomedicine field provides a new method for destroying bacterial biomembrane, the weak electric field can prevent bacteria from gathering into biomembrane, and if the bacterial biomembrane is existed on wound, the weak current can decompose the bacterial biomembrane, the skin wound body fluid is used for conducting electricity, the weak electric energy can not cause harm to patient, at most, the weak electric energy has little tingle, but enough can decompose the bacterial biomembrane and prevent the bacterial biomembrane from forming again, thereby avoiding further infection.

Therefore, the electronic sterilization dressing is produced at the same time. For example, patent publication No. CN107206235A discloses a "method and device for improving wound healing", which uses electrodes to cooperate with ointment and medicine to generate electric current for sterilization and disinfection, and has a complicated structure and low current stability. For example, patent publication No. CN107073261A discloses a wound care bandage and wound healing method, which uses conventional batteries and circuits, and has high cost, complicated connection of power supply, wires and electrodes, large volume and complex structure. Most of the existing electronic sterilization dressings have the problems, are inconvenient to use in practice and are not suitable for large-scale popularization and application.
