Research and Manufacture of Spine Traction Bed Controlled by Microcomputer / 医疗卫生装备

ABSTRACT

Objective To develop a spine traction bed controlled by microcomputer,which can be used to treat patient with its function of TCM(traditional Chinese medicine)hazing diadermic fumigation and spine traction.Methods Modern hazing diadermic principle was utilized to make the effective component absorbed through skin on treating location.At the same time,PID incremental calculation and fuzzy control theory were used in the process of control ling spine traction through real-time closed loop.Through experiment and practice,this product met the standards and had a total effective rate of 96% without any side effects.Results The setting scope of temperature was 35?C-55?C with deviations of temperature controlling,displaying,uniformity and fluctuation less than 2?C.The setting scope of traction controlling was 10-80 kg with testing index less than 2kg both at "dynamic" and "static" status.The whole machine met the pragmatic needs in clinic.Conclusion This product adopts new technology of TCM hazing diadermic fumigation,PID incremental calculation and fuzzy control theory to obtain the goal of "real-time closed control through mechanical and electrical integration".This product can be applied not only in clinic for the need of TCM Tuina,but also in departments of traumatology,orthopedics,physiotherapy and rehabilitation.
