Abstract

The invention provides a blood pressure collecting terminal and a method and coronary analysis system for obtaining the arterial blood pressure. The blood pressure collecting terminal comprises a body, and a first power driving device, a blood pressure collecting device and a first control device which are all connected with the body. The first power driving device is arranged on the body and usedfor driving liquid in an external infusion device to flow. The blood pressure collecting device is arranged on the body and connected with the first control device and an external interventional device and is used for collecting the arterial blood pressure. The first control device is connected with the external infusion device and used for controlling the liquid flowing direction of the infusiondevice so that liquid can flow from the infusion device to the first control device. By turning on the first control device, the blood pressure collecting device is communicated with the external infusion device and the atmosphere at the same time, the first power driving device drives liquid in an infusion pipe to flow, automatic gas exhausting is realized, and operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a blood pressure collection terminal, a method for obtaining invasive arterial pressure, and a coronary artery analysis system. Background technique [0002] Fractional flow reserve (FFR) refers to the ratio of the maximum blood flow that can be obtained by the myocardial region supplied by the coronary artery to the maximum blood flow that the same region can theoretically obtain under normal conditions in the case of coronary artery stenosis. The ratio of mean intracoronary pressure (Pd) at the distal end of stenosis to mean aortic pressure (Pa) at the coronary ostium under maximum hyperemia. To calculate fractional flow reserve (FFR), it is necessary to first obtain aortic pressure data with the help of equipment, such as systolic pressure, diastolic pressure and mean pressure of aortic pressure. [0003] The data of aortic pressure measured by a sphygmomanom...
