DEVICE AND METHOD FOR MEASURING VIBRATION TRANSMITTANCE OF STERNUM

摘要

The invention relates to a method, device and system for measuring vibration transmittance of a sternum noninvasively. The method comprises producing vibration, transmitting the vibration to a first side the sternum through skin and soft tissues, obtaining response data of the sternum from a second side of the sternum through skin and soft tissues, which first and second sides of the sternum are on different sides of the midline of the sternum, and processing said response data for determining transmittance of vibration of the sternum. The response data may be used for defining state of a patient such as sternal instability of the breastbone or abnormal healing in the sternum after open chest surgery by surgeons.
