Title (EN) MEDICAL CONDUCTIVE HYDROGEL, PREPARATION METHOD THEREFOR AND USE THEREOF
(FR) HYDROGEL CONDUCTEUR MÉDICAL, SON PROCÉDÉ DE PRÉPARATION ET SON UTILISATION
(ZH) 医用导电水凝胶及其制备方法与应用
Abstract:
(EN) Disclosed are a medical conductive hydrogel, a preparation method therefor and the use thereof. The hydrogel comprises 8.00-20.00% of a water-soluble macromolecular material, 0.05-2.00% of -zirconium hydrogen phosphate, 0.20-10.00% of a salt electrolyte and 68-91% of water. In the hydrogel, the -zirconium hydrogen phosphate and the dissolved salt electrolyte are dispersed in the water-soluble macromolecular material. By means of the synergistic effect of the -zirconium hydrogen phosphate and the dissolved salt electrolyte with the water-soluble macromolecular material, the hydrogel has excellent biocompatibility and conductivity, and can be used in the medical field. No hot press moulding is required during preparation, thereby simplifying the preparation process, reducing production costs, and being safety and environmentally friendly.
(FR) La présente invention concerne un hydrogel conducteur médical, son procédé de préparation et son utilisation. L'hydrogel comprend 8,00 à 20,00 % d'un matériau macromoléculaire soluble dans l'eau, 0,05 à 2,00 % de phosphate d'hydrogène-zirconium, 0,20 à 10,00 % d'un électrolyte salin et 68 à 91 % d'eau. Dans l'hydrogel, le phosphate d'hydrogène-zirconium et l'électrolyte de sel dissous sont dispersés dans le matériau macromoléculaire soluble dans l'eau. Au moyen de l'effet synergique du phosphate d'hydrogène-zirconium et de l'électrolyte de sel dissous avec le matériau macromoléculaire soluble dans l'eau, l'hydrogel dispose d'une excellente biocompatibilité et d'une excellente conductivité, et peut être utilisé dans le domaine médical. Aucun moulage par pressage à chaud n'est nécessaire pendant la préparation, ce qui simplifie le processus de préparation, réduit les coûts de production, et est sûr et respectueux de l'environnement.
(ZH) 一种医用导电水凝胶及其制备方法与应用。该水凝胶包括水溶性高分子材料8.00-20.00%、α-磷酸氢锆0.05-2.00%、盐类电解质0.20-10.00%、水68-91%。该水凝胶在水溶性高分子材料中分散α-磷酸氢锆和溶解盐类电解质,通过α-磷酸氢锆和溶解盐类电解质与水溶性高分子材料的协同作用,该水凝胶具有优异的生物相容性和导电性,能够被用于医用领域。制备时不需热压成型,简化了制备工艺,降低了生产成本,安全环保。
