The equipment (1) of endovascular pressure for a fluid in a container directly detected allows to increase measurement accuracy, it is related with force model quantity, it is detected by an air-flow, it is fluidly connected in capillary channel with the endovascular of its pressure of application thereon, by separating such air-flow simultaneously from the outside in each process segment, then by preventing that fluid, its pressure must measure, therefore it is contaminted or infected, it include: in this meaning, with first valve (13, 14) a connector (5), it limits a connecting terminal chamber (63), it, which is arranged, holds outside needle element (11) one and holds needle element (11) to the connector (5) from described by a conduit (6) and mutually circulate with one or more of capillary channels (16) Including at least a pressure sensor (25) and including for a reusable element (2), it is connected to the connector (5) in the mobile communication terminal chamber (63) of disposable portion (3), it is easy to put into the inner space (50) for communicating reusable element (2), it receives at least one described pressure sensor (25), with the mobile communication terminal chamber (63), the valve (13,14) opening is determined by the connection between reusable element (2) and the disposable portion (3).
