| titleOfInvention | Anti-infection electrostatic spinning degradable hernia patch and preparation method thereof |
| abstract | The invention relates to the technical field of hernia patch preparation, in particular to an anti-infection electrostatic spinning degradable hernia patch and a preparation method thereof. The invention provides a preparation method of an anti-infection electrostatic spinning degradable hernia patch, which comprises the following steps: mixing the polyurethane solution, the gallic acid and the polyvinyl alcohol to obtain a spinning solution; carrying out electrostatic spinning on the spinning solution to obtain a spinning film; and soaking the spinning film in water, and dissolving out polyvinyl alcohol to obtain the anti-infection electrostatic spinning degradable hernia patch. In the invention, polyvinyl alcohol is used as a sacrificial layer, and is dissolved in water after spinning forming, so that the pore size and porosity can be improved on the basis of ensuring the integrity of the overall structure of the hernia patch, and the infection can be inhibited; in addition, the polyurethane can be completely degraded, and the gallic acid serving as a cross-linking agent can improve the strength and elasticity of the polyurethane and can also improve the antibacterial property of the hernia patch. |
