Title (EN) METHOD FOR PREPARING SINGLE-PHASE MODIFIED SODIUM HYALURONATE GEL
(FR) PROCÉDÉ DE PRÉPARATION DE GEL DE HYALURONATE DE SODIUM MODIFIÉ À PHASE UNIQUE
(ZH) 制备单相修饰透明质酸钠凝胶的方法
Abstract:
(EN) The present invention relates to a method for preparing a single-phase modified sodium hyaluronate gel. The gel is biocompatible. Same undergoes a cross-linking reaction with reasonable parameters. The cross-linking reaction is terminated by removing a cross-linking agent and a cross-linking environment by means of dialysis. The mixing with a mobile phase after homogenization further enhances the degree of aggregation and applicability of the gel. The addition of an anesthetic is based on considerations for comfort. Also disclosed are the gel and uses thereof.
(FR) La présente invention concerne un procédé de préparation d'un gel de hyaluronate de sodium modifié à phase unique. Le gel est biocompatible. Il subit une réaction de réticulation avec des paramètres raisonnables. La réaction de réticulation se termine par l'élimination d'un agent de réticulation et d'un environnement de réticulation par dialyse. Le mélange avec une phase mobile après homogénéisation améliore en outre le degré d'agrégation et d'applicabilité du gel. L'ajout d'un anesthésique est basé sur des considérations de confort. L'invention concerne également le gel et ses utilisations.
(ZH) 本发明涉及一种制备单相修饰透明质酸钠凝胶的方法,该凝胶是生物相容性的,其通过合理的参数进行交联反应,并通过透析除去交联剂和交联环境以终止交联反应,均质化后与流动相的混合进一步增强凝胶的集聚性和可应用性,麻醉剂的添加是基于应用舒适性考虑,本发明还公开了凝胶及其用途。
