摘 要：

The invention concerns a device for measuring the flow rate of a liquid

circulating in a pipe and extracted from or introduced in the human body. The device comprises two pressure measuring means (12, 14) and a conduit element (16) whereof the ends are respectively connected to the measuring means, the conduit element being substantially rigid and having an internal diameter equal to that of the pipe portions (22, 26) to produce a laminar flow of said liquid. Each pressure measuring means

comprises means forming a pipe with an axial bore whereof the wall inner surface (41) substantially provides continuity to the pipe and an orifice (42) passing through the wall and emerging in the inner surface and a pressure sensor (46) for measuring said liquid pressure in the
