Abstract
The invention discloses a micro-metal tube thrombus elasticity detection device and method based on an L(0,1) longitudinal mode guided wave. The device includes a device housing, a temperature control module, a micro-metal tube, and a magnetostrictive assembly. The housing is externally connected to the temperature control module to realize internal constant temperature, the replaceable micro-metal tube is installed inside, the magnetostrictive assembly composed of a permanent magnet and a coil is provided at one end outside the tube. An L(0,1) longitudinal mode guided wave is excited on the micro-metal tube. When liquid viscosity within the tube changes, the energy attenuation of the guided wave propagating along the tube is different. The energy attenuation of the guided wave is defined through the attenuation rate of multiple echo peak values to reflect changes in the blood viscosity.
