Significantly, the pressure transducer, the opaque cap, the temperature compensation circuit, and the solder pads are all positioned on the same side of the dielectric substrate sheet, thereby greatly facilitating manufacture and assembly of the apparatus. Thus, a single silicon chip can be formed to comprise both the pressure diaphragm and the measuring circuitry of a pressure transducer. 5 is an enlarged, cross-sectional view taken along lines 5--5 of FIG. For example, a number of separate, delicate assembly steps are often required in order to arrange the various components of the transducer devices into a single unit. After the indwelling catheter is positioned within a patient as described above, the other end of the catheter is connected to pressure transducer. It will be readily appreciated that housing 12 of transducer apparatus 10 could also have a wide variety of different shapes. It is, therefore, an object of the present invention to provide a disposable pressure transducer apparatus wherein the semiconductor transducer of the apparatus is effectively shielded from exposure to light. Further, since all of the electrical components of the apparatus are mounted on the side of the dielectric substrate which is away from the fluid channel, and since a fluid-tight silicone gel seal is formed between the other side of the dielectric substrate and the housing, the present invention provides a disposable pressure transducer apparatus wherein the electrical circuitry of the apparatus is electrically isolated from the patient, thereby minimizing the likelihood that the patient will receive an electrical shock. 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. In addition, cable 14 should be shielded so as to minimize electromagnetic interference with the signals being transmitted along cable 14. In light of the foregoing, it is a primary object of the present invention to provide a disposable pressure transducer apparatus which is accurate, safe and economical.

Also, semiconductors (particularly silicon semiconductors), are quite sensitive to light, such that exposure of semiconductor pressure transducers to light can produce transient variations in the pressure readings. Cap 90 thus protects pressure transducer 80, together with the associated wires 84 and solder pads 78, from mechanical injury. Further, it is an object of the present invention to provide a disposable pressure transducer apparatus wherein the electrical circuitry of the apparatus is effectively isolated from the patient, thereby minimizing the likelihood that the patient will receive an electrical shock from the apparatus. It should be noted that mounting pressure transducer 80 directly to substrate 70 in this manner, thereby eliminating the need for a separate pyrex pedestal, reduces the time and cost required for manufacture and assembly. A disposable blood pressure transducer system for use with a catheter with or without a catheter flush/flow valve. Because of these conditions, therefore, the prior art disposable pressure transducer devices will sometimes not produce data having the desired degree of accuracy. The catheter is generally also connected to a suitable continuous flush device or heparin drip to help prevent clotting around the tip of the catheter. • Monitoring pressure can also prevent a system integrity breach protecting operators from potential exposure to potent molecules or acids and bases. These are the advantages of Elcam's Sense-IT™ Integrated Disposable Pressure Transducer. Because of these and other advantages, therefore, direct blood pressure measurement and monitoring has become part of the routine treatment for critically ill patients.
