Abstract: A device for the detection of endovascular pressure of a fluid in a vessel detects through an air column which inside capillary ducts, is in contact with endovascular fluid which exerts its pressure thereon, by separating such air column from outside in each process phase, and then prevents that the fluid from being polluted or infected thereby, and including a connector with a valve, which defines a connection terminal cavity arranged outside a needle-holding element and is in fluid communication with the capillary ducts through a duct extending from the needle-holding element to the connector; and a re-usable element including a pressure sensor and connector to connect to the connector at the terminal cavity of the disposable portion, which receives the pressure sensor, with the terminal cavity, the opening of the valve being determined by the connection between the re-usable element and the disposable portion.
