Intravascular pressure measurement system with developing ring

Abstract

The invention relates to an intravascular pressure measuring system with a developing ring. The intravascular pressure measuring system comprises a first pressure measuring device, a withdrawing device and a host, wherein the first pressure measuring device is provided with a first pressure sensor and the developing ring; the withdrawing device is connected with the first pressure measuring device and controls the first pressure measuring device to withdraw in the blood vessel, and in a withdrawing process, the first pressure sensor obtains first pressure data in the blood vessel, wherein the first pressure data comprises first pressure waveforms of a plurality of cardiac cycles; the host comprises a display device, obtains a blood vessel X-ray radiography image and an X-ray real-time image of a preset part, is connected with the withdrawing device and is configured to receive the first pressure data, and the host obtains a pressure distribution diagram of the blood vessel of the preset part on the basis of the X-ray radiography image, the X-ray real-time image and the first pressure data; and the X-ray radiography image, the X-ray real-time image and the pressure distribution diagram of the blood vessel of the preset part are displayed on the display device at the same time.

Description

[0001] This application is filed on February 22, 2020 , the application number is 2020101095894 , the name of the invention is Intravascular pressure measurement system divisional application of the patent application. technical field [0002] The present disclosure specifically relates to an intravascular pressure measurement system with a visualization ring. Background technique [0003] Coronary artery disease is one of the leading causes of death worldwide, and the ability to better diagnose, monitor, and treat coronary artery disease can save lives. Coronary angiography is a technique routinely used to evaluate coronary artery stenosis, but coronary angiography cannot reflect the real situation of coronary vascular function, so it is basically impossible to clarify whether the coronary artery stenosis is related to the patient's myocardial ischemia, symptoms relevant. At present, the clinical method for judging coronary artery stenosis is mainly the technique of ...

Problems solved by technology

[0004] However, there are following defects in the process of obtaining FFR: before measuring FFR, it is necessary to inject maximum hyperemia-inducing drugs (such as adenosine, adenosine triphosphate ATP) into the coronary arteries, so that the coronary arteries are in the maximum hyperemia state, and this process will increase the clinical operation time and give While bringing incompatibility to patients, it will greatly increase medical expenses, and it will also cause allergic reactions in patients

[0005] In addition, the FFR value obtained by the existing intravascular pressure measurement system can only judge whether the blood flow transmission between the two measurement points is blocked, and cannot give the blood flow transmission between the two measurement points

When there is a series of lesions or diffuse lesions between two measurement points, the FFR value obtained by the existing intravascular pressure measurement system has little clinical significance

Moreover, the intravascular pressure measurement system in the prior art can only qualitatively determine whether a stent needs to be implanted, and cannot provide quantitative information such as the size of the site where the stent needs to be implanted.
