The invention provides a catheter capable of measuring pressure in a blood vessel, comprising a distal cannula, a pressure sensor and a proximal part, wherein the distal cannula is provided with a conducting wire inner chamber, the conducting wire inner chamber can receive a separate medical conducting wire in a sliding manner, the pressure sensor is arranged outside the distal cannula, and is arranged to measure blood pressure in the blood vessel and generate a blood pressure signal, the proximal part is coupled with the distal cannula, and comprises a signal channel and a connecting catheter, the signal channel is arranged to transmit the blood pressure signal from the pressure sensor, the connecting catheter is arranged to support the signal channel and move the distal cannula, an annular cannula is arranged at the front end of the distal cannula as a location identifier, and the annular cannula has flexibility and comprises a material non-transparent to X rays. According to the catheter capable of measuring the pressure in the blood vessel provided by the invention, as the annular cannula which has the flexibility and comprises the material non-transparent to the X rays is provided as the location identifier, position of the pressure sensor can be located conveniently, and injury to the blood vessel caused during the operation is reduced.
Description
[0001] This application is filed on February 19, 2016 , the application number is 201610095320.9 , the name of the invention is Blood vessel internal pressure measuring catheter divisional application of the patent application. technical field [0002] The invention relates to a catheter for measuring intravascular pressure. Background technique [0003] For many cardiovascular diseases such as coronary heart disease, percutaneous coronary intervention (PCI) is currently a relatively effective treatment. The traditional method of judging whether to implement interventional treatment (such as angioplasty or stent placement) is that doctors use coronary angiography to visually observe the degree of stenosis of coronary vessels. However, this traditional judgment method cannot help doctors make very accurate judgments, and may lead to overtreatment by doctors. [0004] In recent years, in order to more accurately judge whether a patient really needs interventional therap...
