An electrospinning device (1; 30) is provided comprising: a container (2) for holding a liquid comprising a polymer melt or a polymer solution; a nozzle (3) arranged to outlet a stream of the liquid from the container; a collecting surface (4) for collecting electro spun material coming from the nozzle during an electrospinning process so as to form a fibrous structure (8) on the collecting surface (4); a voltage supply system (5) arranged to create a voltage difference between the nozzle and the collecting surface (4), one or more electrostatic emitters (10; 38) arranged to locally distribute positive and/or negative ions onto the fibrous structure, and one or more rotatable bodies (6; 36) arranged to cause the collecting surface (4) to face the nozzle (3) and the electrostatic emitters (10; 38) in turn.

According to one embodiment, a spinning apparatus includes a spinning head and a rotational brush. An organic material is filled up inside the spinning head, and the spinning head ejects the organic material on a surface of a base to form a sheet of the organic fiber on the surface of the base. The rotational brush includes a plurality of brush bristles and is rotated while the brush bristles are in contact with the sheet in the surface of the base. The rotational brush strips the organic fiber from a part of the sheet by the rotation.

Systems, apparatuses, and methods for reducing humidity of air adjacent to a nozzle of an electrospinning apparatus, charged solution output by the nozzle, a solution path between the nozzle and a deposit surface, and/or the deposit surface. The apparatus can be configured to controllably output the charged solution and gas of a predetermined dryness for deposit of the charged solution on the deposit surface. The gas of the predetermined dryness can be provided adjacent to a nozzle tip of the nozzle from where the charged solution is output. The gas of the predetermined dryness may be output in a predetermined direction toward a focal point at, in front of, or behind the nozzle tip.

An applicator is disclosed for applying a treatment solution to a treatment site of a patient. The applicator can include an applicator housing comprising a treatment solution reservoir.
