METHOD AND DEVICE FOR CONTINUOUS BLOOD PRESSURE MONITORING AND ESTIMATION

A method and device is provided for the continuous estimation of the blood pressure using a noninvasive technique. The method involves sensing of the displacement signal generated by the palpation of the radial artery. The radial artery is modelled as a cylindrical voight type viscoelastic tissue for the estimation of the personalized blood pressure. The model includes the displacement signal and a set of parameters as an input. The set of parameters include a mean radius of the artery, a radius at zero mmHg, a viscoelastic damping parameter, an elasticity of the artery and a thickness of wall of artery. The method involves the optimization of the set of parameters using heuristic optimization techniques, which helps in the estimation of the systolic and diastolic blood pressure. The method and device can also be personalized for individualized monitoring and estimation of the blood pressure of the person. 提供用于使用无创技术来连续估计血压的方法与装置。本方法涉及感测通过触诊径向动脉生成的位移信号。径向动脉是仿照作为个圆柱形的沃伊特型粘弹性组织以便估计个性化血压。此模型包括位移信号与参数集合作为输入。此参数集合
