    • Apparatus and method for electrospinning fibers in which the apparatus includes a spray head having a longitudinal axis and including at least one electrospinning element disposed in a peripheral wall of the spray head surrounding the longitudinal axis. The electrospinning element includes a passage by which a substance from which the fibers are to be electrospun is provided to a tip of the extrusion electrospinning element. The electrospinning element extends from the peripheral wall in a direction from the longitudinal axis and is configured to electrospin the fibers by electric field extraction of the substance from the tip of the extrusion electrospinning element. Accordingly, the method includes providing a substance from which the fibers are to be composed to a tip of an electrospinning element in a peripheral wall of a spray head having a longitudinal axis, rotating the spray head or a collector configured to receive the fibers around the longitudinal axis, applying in a direction from the longitudinal axis of the spray head an electric field to the tip of the electrospinning element to electrospin by electric field extraction the substance from the tip of the electrospinning element to form the fibers, and collecting the fibers on the collector.
    • 用于静电纺丝的装置和方法,其中所述装置包括具有纵向轴线的喷头,并且包括设置在围绕纵向轴线的喷雾头的周壁中的至少一个静电纺丝元件。 静电纺丝元件包括一个通道,通过该通道将纤维被电纺的物质提供到挤压静电纺丝元件的尖端。 静电纺丝元件从周壁沿着纵向轴线延伸,并且构造成通过从挤出静电纺丝元件的尖端电场提取物质来电纺纤维。 因此,该方法包括在具有纵向轴线的喷头的周壁中提供要从其中构成纤维的物质到静电纺丝元件的末端,旋转喷头或收集器,该收集器被配置成围绕 纵向轴线,从喷头的纵向轴线的方向将电场施加到电纺丝元件的尖端,以通过从静电纺丝元件的尖端电场提取物质以静电纺丝以形成纤维,并将纤维收集在 收藏者。
