Electrospinning apparatus

Abstract

The invention discloses an electrospinning apparatus comprising an AC high-voltage generator, a liquid supplying device including a micro-injection pump, an air supplying device, a spraying head including a liquid supplying channel connected with the liquid supplying device and an annular air supplying channel connected with the air supplying device, and a receiver including at least two rod-like supporting arms, a rotating shaft and a transmission device driving the rotating shaft to rotate. The air supplying channel sleeves the liquid supplying channel; an end part of an outlet section of the liquid supplying channel is provided with a tapered tipped end; the spraying head is connected with the AC high-voltage generator; one end of the supporting arm is fixedly connected with the rotating shaft and the other end is suspended in the air; the adjacent supporting arms are arranged at intervals; all the supporting arms form a bowl type revolving surface during the rotation of the rotating shaft; and the bowl typerevolving surface is opposite to a liquid outlet and an air outlet of the spraying head. Fibers with tiny diameters can be formed by the use of the electrospinning apparatus; the fiber filament diameters are evenly distributed and the fibers have fluffy structure and excellent mechanical properties; backswinging air flows can be avoided; and the electrospinning apparatus can be widely applied to organization engineering field.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to an electrostatic spinning device. Background technique [0002] In recent years, the technology in the field of tissue engineering has received high attention and in-depth research. The principle of tissue engineering is to induce and promote a series of physiological activities such as cell growth, migration and proliferation in vivo or in vitro, and finally form an organ with a three-dimensional structure. or organization. One such application is nanofibrous tissue engineering scaffolds. [0003] At present, electrospinning is usually used to prepare nanofibrous tissue engineering scaffolds. In a typical production method, air-blown polymer solution is used to prepare nanofibers on a large scale. However, the diameter of air-spun fibers is relatively large, and traditional air-spun Closed receivers or cylindrical receivers are often used. Under the action of high-speed airfl...

[0003] At present, electrospinning is usually used to prepare nanofibrous tissue engineering scaffolds. In a typical production method, air-blown polymer solution is used to prepare nanofibers on a large scale. However, the diameter of air-spun fibers is relatively large, and traditional air-spun Closed receivers or cylindrical receivers are often used. Under the action of high-speed airflow, it is easy to generate recoil airflow, which affects the directional deposition of fibers.
