In order to provide additional shielding from light, one side of substrate 70 may be coated, at least in part, by some type of opaque coating. Significantly, using this type of diaphragm/circuitry configuration, it is possible to obtain quite accurate measurements of even small pressure pulses acting on the pressure diaphragm. When a patient no longer requires blood pressure monitoring, transducer apparatus 10 may be disconnected and discarded. United States Patent 5993395 . A novel disposable pressure transducer apparatus for monitoring human blood pressure. In addition, a longer connecting cable can be quite inconvenient to use, in that it is first necessary to locate and then untangle a suitable cable and thereafter properly connect it to both cable 14 and a monitor. A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. Further, as illustrated, shell 40 may be provided with a recessed shelf 42, and back plate 50 may be formed so as to fit snugly within recessed shelf 42.
