수종 시판 경추보조기의 물성에 관한 평가조사

Abstract

This is to investigate the physical properties of the commercially available Soft, Thomas, Minerva, and Philadelphia cervical braces which are widely used in orthopedics, neurosurgery, and rehabilitation medicine clinics as assisting devices for physical stabilization of cervical vertebrates, to use as a basic data for designing new type brace. Tensile strengths were observed by universal mechanical measuring device and Thomas brace required the highest stress to break by tensile stress. Durabilities against continuous frictional forces were also determined, and Minerva brace demonstrated the longest frictional time until being perforated. According to these results, poly ethlene is recommendable as a frame and preparation of pores in the material is favorable to provide ventilation to skin.
