Problems solved by technology

However, the existing plasma generating devices are basically fixed or hand-held, and it is difficult to effectively treat non-planar objects in a large area, and most devices require external gas
The Chinese patent document CN106488641A, whose publication date is March 8, 2017, discloses a portable plasma device that can be used for wound disinfection. A high-voltage DC power supply is used to discharge a serrated stainless steel electrode to generate a plasma jet, and the object is treated during the treatment process. It is necessary to wear an additional grounding conductive wrist strap, the overall operation is inconvenient and it is not suitable for the treatment of non-flat object surfaces
The Chinese patent document CN106668897A with the publication date of May 17, 2017 discloses a flexible portable plasma sterilization device, which realizes the sterilization and disinfection of non-flat surface objects through a flexible medium layer and an elastic metal mesh, but it needs to be adjusted artificially according to the processing object Curved surface and not suitable for direct treatment of wound sites

Abstract

The invention discloses a flexible plasma sticker comprising a flexible insulating layer 1, an electrode and a flexible insulating layer 2 which are arranged in sequence. The flexible insulating layer1 is provided with a protrusion used for forming a gap between the flexible insulating layer 1 and a surface to be processed. Based on the principle of dielectric barrier discharge, the invention provides the flexible plasma sticker which can generate large-area and low-temperature micro-plasma, the curved surface adjustment can be carried out according to the condition of the surface to be processed, the flexible plasma sticker is directly attached to a wound surface or a skin lesion to carry out large-area treatment, and the flexible plasma sticker is easy and convenient to use.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a flexible plasma paste. Background technique [0002] Plasma is a new focused state of matter in addition to solid, liquid, and gaseous states, which is called the fourth state of matter. It contains a large number of charged ions, high-energy electrons, excited state active atoms and other components, especially low-temperature plasma due to its temperature. The characteristics of low, active biochemical properties, etc., have attracted much attention in the field of biomedicine in the past two decades. Many studies at home and abroad have shown that the components of low-temperature plasma can effectively destroy the cell structure of microorganisms and cause their apoptosis; can induce the expression of vascular endothelial growth factor, promote wound epidermal regeneration, granulation tissue proliferation and collagen precipitation, and promote fibroblast prol...
