建立检测内出血点的量化技术有助于进一步提高超声止血的效率。提出了描述动脉血管内出血的多维度复合模型。由一个描述破裂血管的二维模型和一个描述下游血管系统响应的一维模型组成。计算机仿真及初步的活体实验结果证明了理论模型的有效性,并表明内出血时的血流速度波形会产生大幅度单波峰或收缩速度峰的相位延迟,该结果可作为自动快速检测血管破裂的量化参数。 The establishment of quantitative detection of bleeding within the technology will help to further improve the efficiency of ultrasound to stop bleeding. A multidimensional complex model describing intra-arterial bleeding was proposed. It consists of a two-dimensional model that describes the ruptured vessel and a one-dimensional model that describes the response of the downstream vascular system. Computer simulation and preliminary in vivo experimental results demonstrate the validity of the theoretical model and show that the blood flow velocity waveforms during internal bleeding have a large phase delay of peaks of single or contractile velocity that can be used as an automatic and rapid measure of vessel rupture quantification parameter.
