  • Pressure transducer dome
    Patent number: 4462409
    Abstract: A pressure transducer for use in a direct blood pressure measuring system includes a domed portion which is connected to a line interposed in a patient's blood supply system. A sterile solution serves to interface the patient's blood system and the pressuring measuring apparatus. An asymmetrical configuration of the interior cavity in the domed portion of the transducer, which cavity is in the fluid flow path, as well as a convex surface formed on the top face of the cavity improve the reliability of the transducer by avoiding standing waves and bubbles in the fluid in the cavity. Flow lines intersecting the cavity are tapered to improve impedance matching with the cavity.
