Conductive layer of self-sticking conductive film

Abstract

The invention provides a conductive layer of a self-sticking conductive film. The conductive layer is prepared from the following raw materials in parts by mass: 6 parts of glycerol, 5.5 parts of nylon fiber, 13 parts of gelatin, 2.3 parts of polyester, 3.5 parts of silver-carried copper silicone oil, 4 parts of polytetrafluoroethylene, 2.8 parts of rosin and 1.2 parts of poly(glycolic-lactic acid) (PGLA). The conductive layer is prepared by heating the rosin to be in a molten state, then adding the glycerol and the gelatin, stirring sufficiently for uniformly mixing, then adding the nylon fiber, the polyester, the polytetrafluoroethylene and the poly(glycolic-lactic acid), maintaining the temperature at 175 DEG C in a closed container, continuing stirring for 5min, finally adding the silver-carried copper silicone oil, continuing stirring for 15min, injecting into a mould to prepare a flake with the thickness of 2-3.5mm. The conductive layer is conducted with a therapeutic electrode, and has good electrical conductivity and adhesion, relatively good elasticity and strong shape restoration.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a conductive layer of a self-adhesive conductive film. Background technique [0002] A specific area of ​​the gastrointestinal tract can drive the contraction of gastrointestinal smooth muscle and control the basic bioelectrical rhythm of the gastrointestinal tract. In medicine, this specific area is called a gastrointestinal pacemaker (Pacemaker). [0003] The working principle of the gastric motility therapy device is based on the fact that the electrical activity of the gastrointestinal pacemaker can be driven by the external current stimulation, which promotes the disordered gastrointestinal electrical activity to produce a follow-up effect to restore the normal rhythm, thereby achieving the treatment of various functional gastrointestinal diseases the goal of. [0004] The therapeutic electrode usually acts on the human body through a self-adhesive conductive film to realiz...

AI Technical Summary

Problems solved by technology

The existing self-adhesive conductive film used for gastric motility therapy instrument usually needs to use alcohol and degreasing liquid to degrease and disinfect the skin surface before sticking to the skin, and then stick the self-adhesive conductive film on the skin. It is troublesome to use on degreased and disinfected skin. If the skin surface is not degreased or cleaned, it will affect the conductivity and adhesion of the self-adhesive conductive film
