基于arm+fpga的超声骨伤理疗仪的研究word格式论文.docx

AbstractAs a kind of important physical treatments, ultrasonic therapy technology has been moved forward in recent two decades, application field increasingly wide. It has been confirmed on clinical that ultrasound can speed up fracture healing. But the ultrasound launched by general ultrasonic therapy instrument is high intensity, weak penetrability, thus it takes ineffective in the deeper focal such as bone, although it takes effect in skin, muscle and connective tissues. In recent years, special ultrasonic treatment wave for promoting bone healing was developed, which is low intensity ultrasound and use low frequency sine or pseudo random sequence as the modulating signal, that lead to the advantages of the ultrasound treatment which has strong penetrating power and causes small thermal. It can be use to accelerate fracture healing with stimulating secretion of CGRP (Calcitonin Gene Related Proteins) in each fracture healing phase, shortenning the time of treatment, and reducing the ratio of delayed union or nonunion.With the rapid development of electronic and information technology, the intelligentize degree of medical instrument was higher and higher also. The design of ultrasonic therapy instrument was studied in this dissertation specially to physiotherapy for fracture, employing the special ultrasonic treatment wave for fracture healing, while the instrument’s intelligent was emphasized with the purpose of designning a physiotherapy instrument with friendly interface, easy operation, high control precision and double channel output. As a physiotherapy apparatus designed for fracture specially, this ultrasonic therapy instrument can promote the clinical application of ultrasonic physiotherapy for bone healing, and help to pull the many fracture patients through as soon as possible.System modeling and design was made in this dissertation using the design thought of object-oriented and application-oriented. To build the system framework, the framework of ARM a
