An ultrasonic positioning method for real time measuring the distance between the epidural needle and the epidural space is provided. The ultrasonic positioning method at least includes a puncturing step; an advancing step; a positioning step for simultaneous detecting reflected ultrasonic signals from the ligamentum flavum (LF) and dura mater (DM); a replacement step for removing the ultrasound needle transducer and putting an injecting catheter; and an injection step for injecting an anesthetic into the epidural space via the injecting catheter.

The present invention provides an antiglare film, which includes a transparent resin layer, a plurality of transparent hollow particles and a plurality of transparent solid particles. The hollow particles and the solid particles are distributed in the transparent resin layer, while the hollow particles are partially exposed thereon. The refraction index of the hollow particles and the refraction index of the solid particles are different from the refraction index of the transparent resin layer. Applying both the solid particles and the hollow particles mixed together can lead the antiglare film to have an excellent antiglare property, a high contrast and a great clarity.
