Problems solved by technology

However, in the actual application process, ordinary electrospinning equipment has limitations such as large volume, large mass, difficulty in carrying, and non-directional fiber deposition, which seriously restricts the popularization and application of electrospinning technology.

In order to solve the above problems, relevant research workers have made many improvements to the electrospinning device and designed a variety of portable electrospinning equipment. However, the spinning nozzles of this type of equipment mostly use conventional nozzles such as syringe needles. Due to the limitation, it is impossible to penetrate into the structure with a certain depth, and to realize the direct spraying of nanofiber membrane inside the structure with depth, which limits the scope of use of the device
