Abstract: PURPOSE: An electrospinning apparatus is provided to form a coating layer with even thickness without replacing the nozzle by emitting coating layer through the nozzle which formed on the cylinder and improve intensity of the coating layer as the coating solution radiated through the nozzle forms vortex due to collision in order to form the coating layer of complicated and minute structure. CONSTITUTION: An electrospinning apparatus has multiple nozzles(111) penetrating in the periphery and comprises a cylinder(110) filed with coating solution inside; a pressure portion(120) which emits the coating solution through the nozzle by pressurizing the cylinder inside; a collector(130) which integrates the coating solution radiated through the nozzle; and a power supply device (140) which supplies different polarity of power to the cylinder and collector. The pressure portion comprises a piston which inserted inside the cylinder to pressurize the filled coating solution inside the cylinder.

Abstract: PURPOSE: A durability test device for a stent is provided to accurately measure a stent failure time in short time. CONSTITUTION: A durability test device for a stent comprises a tube(20), a pressure generator part(30), a connection part(40), a power supply part and a resistance meter(60). A stent(90) is built in the tube. The pressure generator part pressurizes the stent using the inside fluid pressure of the tube. The connection part interlinks the tube and pressure generator part. The power supply part is connected with both ends of the stent by supplying current to the stent. The resistance meter measures the resistance of the stent by using the current applied in the stent and comprises four resistances and a bridge circuit which is connected to the power supply part.
