常肺动脉栓塞(简称肺栓塞)是指肺动脉由于血栓、脂肪、空气等栓塞物堵塞肺动脉各级分支，肺动脉内血流受阻而导致的呼吸循环功能障碍性疾病。具有发病突然，死亡率高，诊断困难，且发病率越来越高的特点。目前临床上对于肺栓塞的筛查主要依赖于D-二聚体的升高，但其具有特异性差得缺点；对肺栓塞的确诊主要依赖核素通气-灌注现象或CT肺动脉造影，但其具有需要搬动患者至放射科并接受核素或造影剂等有害物质的诸多缺点。所以研究一种肺栓塞的简便、快速而准确地诊断手段具有重要的临床意义。Pulmonary embolism (referred to as pulmonary embolism) refers to a respiratory and circulatory dysfunction disease caused by obstruction of pulmonary artery branches at all levels due to embolism such as thrombus, fat, air, etc., and obstruction of blood flow in the pulmonary artery. It has the characteristics of sudden onset, high mortality rate, difficult diagnosis and increasing incidence. At present, the clinical screening for pulmonary embolism mainly relies on the increase of D-dimer, but it has the disadvantage of poor specificity; the diagnosis of pulmonary embolism mainly relies on nuclide ventilation-perfusion phenomenon or CT pulmonary angiography, but it has the disadvantage of poor specificity. The many disadvantages of needing to move the patient to the radiology department and receive hazardous materials such as nuclides or contrast media. Therefore, it is of great clinical significance to study a simple, rapid and accurate diagnostic method for pulmonary embolism.

所述压力传感器为医用压力传感器。The pressure sensor is a medical pressure sensor.
本发明具有以下有益效果：The present invention has the following beneficial effects:
本发明所述的基于肺动脉压力波形分析技术的肺栓塞诊断仪在使用时，压力传感器通过漂浮导管采集肺动脉主干内的压力信息，并将所述压力信息转发至处理器中，处理器根据所述压力信息通过显示器显示所述压力信息随时间的变化曲线，同时处理器显示存储器内存储的正常人肺动脉主干内的压力信息随时间的变化曲线，由于肺栓塞发生后会引起肺血管床面积的急剧减少，从而改变肺动脉系统的阻力及顺应性，在心脏搏出不变或基本不变的情况下，肺动脉内压力必然发生相应地变化，因此可以通过对比用户与正常人的肺动脉主干内的压力信息随时间的变化曲线即可获知用户是否肺栓塞，结构简单，操作方便，具有较强的临床应用价值。When the pulmonary embolism diagnostic instrument based on the pulmonary artery pressure waveform analysis technology described in the present invention is in use, the pressure sensor collects the pressure information in the main pulmonary artery through the floating catheter, and forwards the pressure information to the processor. The pressure information displays the time-varying curve of the pressure information through the display, and at the same time, the processor displays the time-varying curve of the pressure information in the main pulmonary artery of a normal person stored in the memory, because pulmonary embolism will cause a sharp increase in the area of the pulmonary vascular bed. decrease, thereby changing the resistance and compliance of the pulmonary artery system. When the heart beat remains unchanged or basically unchanged, the pressure in the pulmonary artery will inevitably change accordingly. Therefore, the pressure information in the main pulmonary artery of the user and the normal person can be compared Whether the user has pulmonary embolism can be known from the time-varying curve. The structure is simple, the operation is convenient, and it has strong clinical application value.
