Abstract

The invention relates to an intravascular parameter measuring system. The parameter measuring system comprises a parameter measuring device, a data processing device and a intravascular parameter processing device, wherein the parameter measuring device comprises a first pressure measuring part used for measuring a first pressure signal at the near end of a blood vessel stenosis and a second pressure measuring part used for measuring a second pressure signal at the far end of the blood vessel stenosis; the data processing device is connected to the second pressure measuring part and receives the second pressure signal or second pressure data, is in wired or wireless communication connection with the first pressure measuring part, and performs analog-to-digital conversion on the first pressure signal to generate corresponding first pressure data; and the intravascular parameter processing device is in wireless communication connection with the data processing device and determines the fractional flow reserve and / or the non-congestive pressure ratio according to the received first pressure data and second pressure data, or determines the corresponding fractional flow reserve and / or non-congestive pressure ratio according to the received first pressure data and second pressure signal. According to the scheme provided by the invention, the requirements of multi-scene application can be met.

Description

technical field [0001] The present application relates to the technical field of measurement systems, in particular to a system for measuring intravascular parameters. Background technique [0002] According to research, vascular stenosis can induce myocardial ischemia, and evidence of myocardial ischemia must be found before considering revascularization of stenotic lesions. Wherein, through the intravascular parameter measuring device, parameters such as intravascular pressure, flow rate, and temperature can be measured to obtain a series of indices for evaluating the vascular parameters. Intravascular parameters include indices based on pressure data: fractional flow reserve (Fractional Flow Reverse, FFR) and non-hyperemic pressure ratio (Non-Hyperemic Pressure Ratio, NHPR); intravascular parameters also include indices based on temperature or flow and pressure parameters Index: Index of Microcirculatory Resistance (IMR) and Coronary Flow Reserve (CFR). [0003] In rela...
