Claim:
1. An electrospinning device for producing an electrospun fiber from a polymer composition, comprising: a rotatable carrier which is rotatable about a central axis, and which includes a mount segment having two opposite regions and a central point that is disposed between said two opposite regions and that defines a circular running route about the central axis when said rotatable carrier rotates; a collector unit including at least one collector bar which extends along a longitudinal axis to terminate at two opposite ends, which has a middle point between said two opposite ends, and which is rotatable about the longitudinal axis, said opposite ends of said collector bar being respectively mounted to said two opposite regions of said mount segment such that the longitudinal axis is tangent to a reference circular line at said middle point, the reference circular line surrounding and being concentric with the circular running route; a first drive unit coupled to said rotatable carrier so as to drive said rotatable carrier to rotate about the central axis; a second drive unit disposed on said rotatable carrier and coupled to said collector bar so as to drive said collector bar to rotate about the longitudinal axis; a dispenser configured to dispense the polymer composition; and a power supply configured to produce a potential difference between said dispenser and said collector bar so as to permit the polymer composition in said dispenser to erupt from said dispenser as a jet of the polymer composition traveling toward said collector bar to thereby permit the resultant electrospun fiber to be collected on said collector bar, wherein said rotatable carrier is set to rotate about the central axis at a first speed, such that a plurality of longitudinally oriented electrospun fibers are formed on said collector bar.
