    • The invention relates to a process for the preparation of sterile collagen, especially injectable collagen, comprising the steps of preparing a purified acidic collagen solution, filtering that solution through a filter or a sterile membrane, precipitating the filtered solution in the form of a suspension, and concentrating the collagen suspension, in which process the suspension is placed in an elongate supple tubular filter constituting a porous filtering wall, permeable to the liquid but not permeable to the collagen fibres, and is concentrated by the slow passage of the liquid through the wall, without any pressure other than gravity, in order to prevent the filtering wall from becoming clogged by the collagen fibres, optionally with absorption of the liquid by an absorbent layer covering the wall or forming part of that wall, and the subsequent flowing-away and/or evaporation of the liquid via the face of the layer remote from the wall, and collagen preparations obtained.
    • 本发明涉及一种制备无菌胶原蛋白,特别是可注射胶原蛋白的方法,包括以下步骤:制备纯化的酸性胶原溶液,通过过滤器或无菌膜过滤该溶液,以悬浮液的形式沉淀过滤的溶液, 并且将胶原悬浮液浓缩,在该过程中,将悬浮液放置在构成多孔过滤壁的细长的柔性管状过滤器中,该液体可透过液体但不能透过胶原纤维,并且通过液体缓慢通过壁 ,除了重力之外没有任何压力,以防止过滤壁被胶原纤维阻塞,任选地通过覆盖该壁或形成该壁的一部分的吸收层吸收液体,随后流出和 /或通过远离壁的层的表面蒸发液体和获得的胶原蛋白制剂。

    • The invention relates to a biocompatible, bioresorbable and non-toxic adhesive composition for surgical use, for the bonding, in particular, of biological tissues to one another or in an implanted biomaterial, characterized in that it comprises a reactive acidic solution of non-crosslinked and potentially crosslinkable collagen or gelatin modified by oxidative cleavage, at a concentration which is preferably between approximately 5 and 30 by weight. It also relates to reactive acidic solutions and powders based on non-crosslinked collagen or gelatin modified by oxidative cleavage which are used as intermediate products in the preparation of the above-mentioned composition, and to the process for their preparation. It also relates to adhesive kits which comprise, on the one hand, the above-mentioned reactive acidic solution and, on the other hand, a neutralizing solution and which are intended for extemporaneous mixing. Finally it relates to a method of application of the adhesive, composition according to the invention. The invention is particularly useful in the areas of adhesion, haemostasis, leaktightness with respect to liquids or gases, cicatrization, filling, avoiding adhesion in surgery, embolization, as a local system for release of medicamentary active principles, etc.
    • 本发明涉及用于外科用途的生物相容性,生物可再吸收和无毒性粘合剂组合物,用于将生物组织彼此或植入的生物材料结合,特别是其包含非交联的反应性酸性溶液 和通过氧化切割改性的潜在可交联的胶原或明胶,其浓度优选在约5至30重量比之间。 它还涉及基于非交联胶原或通过氧化裂解改性的明胶的反应性酸性溶液和粉末,其用作上述组合物的制备中的中间产物及其制备方法。 它还涉及粘合剂试剂盒,其一方面包含上述反应性酸性溶液,另一方面包含中和溶液,其用于临时混合。 最后,本发明涉及粘合剂,根据本发明的组合物的应用方法。 本发明在粘合,止血,相对于液体或气体的密封性,瘢痕形成,填充,避免手术中的粘连,栓塞,作为释放药物活性成分的局部系统等方面特别有用。
