Abstract:
Device for measuring the pressure of blood in a pipe of an extracorporeal blood circuit, the device comprising:a pressure measurement section having a substantially rigid wall including a hole which is sealed by a closure element; said closure element extending along a general plane, and having an internal face which is in contact with the blood, and an external face which is in contact with ambient air; said closure element structured and arranged to be elastically deformed along a deformation axis which is substantially orthogonal to the general plane, under the effect of the blood pressure; said pressure measurement section structured and arranged to engage with a load sensor so that a portion of the external face of the closure element is, in a rest state, in direct or indirect contact with the load sensor for measuring the force applied axially on the internal face of the closure element by the blood pressure, in order to calculate therefrom the value of said pressure; and said closure element being made in a single piece with the associated rigid wall of the pressure measurement section.
