The invention relates to an L-oxiracetam oral instant membrane, which is prepared from 3 to 20 parts of L-oxiracetam, 40 to 70 parts of membrane-forming material, 10 to 30 parts of filter, 5 to 20 parts of plasticizer and 2 to 4 parts of corrigent, wherein the membrane-forming material is maltodextrin. The L-oxiracetam oral instant membrane can be dissolved by a small amount of saliva in the oral cavity, and can be taken without water for delivery, so administration is convenient. After being stuck to the tongue, the L-oxiracetam oral instant membrane cannot be easily spit out, and therefore is suitable for children with dysphagia. Moreover, because the L-oxiracetam oral instant membrane can be absorbed through the mucous membrane, the first pass elimination effect is prevented, the bioavailability is increased, the dosage of medication is reduced, and thereby the side effect of the medicine is reduced. A preparation method of the invention is simple, the process cost is low, and therefore the preparation method is suitable for mass production.

The invention discloses a medical nanofiber-reinforced hydrophilic composite material and its preparation method and application. The composite material is composed of a hydrophilic base material and nano-short fibers, and the nano-short fibers maintain a crystalline form and are uniformly dispersed on the hydrophilic base. In the material, the mass percentage of the nano-short fiber in the composite material is 1%~30%; the diameter of the nano-short fiber is 200~800nm, and the length is 10~100 μm; the preparation method of the medical nanofiber reinforced composite material of the present invention, The process design is unique, using the solubility difference between the base material and nano-short fibers to evenly disperse the nano-short fibers in the base material, and use the freeze-drying method to obtain a porous sponge-like composite material, which maintains the respective advantages of the two materials. Complementing the disadvantages, a composite material with excellent mechanical properties, good biocompatibility, and good biodegradability is obtained. Its degradation cycle is moderate, and it will not cause postoperative inflammation and postoperative risk of adhesion, which is more suitable for clinical needs. .
