AI Technical Summary
The existing liquid supply system of handheld electrospinning equipment relies on inverted solution bottles or gravity drive, which limits the operating angle, makes the solution prone to leakage or residue, and the pneumatic pipeline lacks a pressure regulation mechanism, posing a safety hazard.
An air pump assembly pressurizes the supply bottle to supply liquid, and a three-way valve and solenoid valve together form an intelligent pressure control unit to ensure constant pressure in the pipeline and automatically balance the air pressure when the machine stops or is powered off to prevent solution backflow or nozzle blockage. The negative ion generator is directly electrically connected to the nozzle assembly to provide a stable high-voltage electric field. The modular nozzle design facilitates replacement and positioning, and combined with the blue light module, it achieves in-situ sterilization of the fiber membrane.
It achieves stable liquid supply in complex operating environments, expands the range of operating postures, reduces maintenance frequency, eliminates the risk of liquid residue and electrode short circuit, ensures jet continuity and fiber diameter uniformity, and is suitable for multi-material switching and continuous clinical operations.
