<p>A pressure sensing apparatus (10) has a pressure sensor component (12) that includes a pressure sensing port (32), a pressure sensor (48) for sensing a pressure of a fluid in the pressure sensing port (32), and a digital processor communicating with the pressure sensor (48) for performing calculations involving fluid pressures sensed. The pressure sensing apparatus (10) further includes a first chamber (30) in fluid contact with the pressure sensing port (32), a second chamber (26) fluidically connectable with a patient's cerebrospinal fluid system, and a membrane (28) located between the first and second chambers so as to transmit fluid pressure from the second chamber (26) to the first chamber (30).</p> |
