[0009] The Chinese invention patent with the application publication number of CN 101864611 A discloses a polylactic acid micro-nano fiber and its preparation method. It blends polylactic acid and water-soluble resin through melt spinning to obtain the blended fiber, and then uses solvent water in a certain The water-soluble polyester is removed at high temperature. The solvent used in this method is environmentally friendly, but at the same time, the solvent water will also affect the degradation of polylactic acid fibers.
[0010] However, none of the above-mentioned technical solutions can meet the technical requirements of lightweight absorbable patch

Abstract
The invention discloses a superfine polyglycollide fiber and a preparation method and device, application and a patch thereof, and belongs to the technical field of biological patch materials. The diameter of the superfine polyglycollide fiber ranges from 5 micrometers to 15 micrometers, and the strength of the superfine polyglycollide fiber ranges from 3.0 cN / dtex to 7.0 cN / dtex. The preparation method and device are both used for preparing the superfine polyglycollide fiber. The superfine polyglycollide fiber can be applied to the patch. The patch is made of the superfine polyglycollide fiber. The superfine polyglycollide fiber prepared through the preparation method and device is small in diameter and high in strength and can be used for manufacturing the light and thin absorbable patch. The gram weight of the patch can be controlled within 8-20 g / m<2>, the foreign matter implant amount is decreased to the greater extent, the flexibility of the patch is high, the pain of a patient can be reduced better, and the requirements of the patient are met.
Description
technical field [0001] The invention relates to the technical field of biological patch materials, in particular to an ultrafine polyglycolide fiber, its preparation method, device, application and patch. Background technique [0002] Regenerative biological patches are extracted from natural organisms through a series of technologies such as advanced cross-linking fixation and multi-directional antigen removal, which can be understood as "cell scaffolds". It is based on the principles of regenerative medicine, molecular biology and immunology After implanted into the human body, it can act as a good scaffold to fill the missing tissue in the damaged part, and under the induction of the material, the human body's self-repair function can gradually grow new tissue in the original position to replace the biological material. Complete the process of organ tissue regeneration. In the early stage, it was mainly used in neurosurgery, repair of inner meninges, repair of esophageal...
