Problems solved by technology

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. Disadvantages of needing to move patients to the radiology department and receive hazardous materials such as nuclides or contrast media

Abstract

The invention discloses a pulmonary embolism diagnostic instrument based on a pulmonary artery pressure waveform analysis technology. The pulmonary embolism diagnostic instrument comprises a floating conduit, a pressure sensor, a processor, a memory and a display. One end of the floating conduit extends into a user's pulmonary artery trunk, the other end of the floating conduit is communicated with the pressure sensor, and the processor is connected with the output end of the pressure sensor, the memory and the display. The pulmonary embolism diagnostic instrument can diagnose whether the user has pulmonary embolism.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a pulmonary embolism diagnostic instrument based on a pulmonary artery pressure waveform analysis technology. Background technique [0002] 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...
