disposable pressure transducer use

Significantly, in an operating room, where there are typically many cables being used, such a procedure can be quite confusing. Solder pads 74 are electrically connected to temperature compensation circuit 72, and solder pads 74, thus, provide a means for electrically connected circuit 72 to cable 14. As shown best in FIG. Further, temperature compensation circuit 72 is used to match the input and output impedance of transducer apparatus 10 with that of the monitor device (not shown), typical impedances being about 350 ohms. 2, substrate 70 is provided with a conventional temperature compensation circuit 72. Thus, for example, one presently preferred embodiment of housing 12 is approximately one inch (2.54 cm) wide, 1.5 inches (3.81 cm) long, and 0.5 inch (1.27 cm) deep. It will be appreciated that such opaque coating reduces the likelihood that light will penetrate substrate 70 and contact pressure transducer 80. Sensors such as the 1620 and 1630 series are used to improve the accuracy and provide real time results of blood pressure changes. Thus, for example, pressure transducer 80 is secured with an adhesive material which is flexible enough to permit pressure transducer 80 to thermally expand and contract without significant interference. 5, a channel 76 is formed around hole 75 in substrate 70 such that channel 76 surrounds pressure transducer 80 when pressure transducer 80 is properly mounted over hole 75 on substrate 70. Consequently, the use of such a cable may give rise to concerns regarding adequate asepsis. … FIG. As a result, the cost of providing such a coating is eliminated. A typical pressure transducer for use in blood pressure monitoring systems comprises a thin diaphragm which is capable of being deflected by the pressure pulses which travel through the above-described fluid column in the catheter. A separate reusable interface cable is used with this system to connect the transducer to a pressure monitor. Pressure transducer 80 is then mounted directly to substrate 70 such that piezoresistive diaphragm 81 of pressure transducer 80 is positioned directly over hole 75 in substrate 70. Also, housing 12 may have any suitable dimensions. As shown, such electrical components are mounted on a dielectric substrate sheet 70. As further depicted in FIG. Privacy Policy 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. There are, however, some significant disadvantages to using a short cable 14 with such a longer connecting cable. Enter Model No. It will be readily appreciated that polyvinyl chloride shield 64 and insulator material 66 may be configured in a wide variety of ways so as to form such a space 68. This lightweight disposable device reports real time intracavitary mean pressures with an oscillating pressure bar graph (Fig. Coupling tube 20 is then filled with fluid, and any air bubbles are removed. Duration of hypotension prior to initiation of effective antimicrobial therapy is the critical determinant of survival in human septic 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. As described below, cap 90 houses the semiconductor pressure transducer and the associated electrical connections between the pressure transducer and the compensation circuit 72. Importantly, because of the foregoing procedure, the need to perform a large number of separate delicate assembly steps is eliminated, thereby helping to reduce the overall cost of the apparatus. DISPOSABLE PRESSURE TRANSDUCER - INSTRUCTIONS FOR USE DESCRIPTION The Meritrans is a pre-calibrated, single use device for physiological pressure measurement. As a result, a long length of cable 14 cannot be economically incorporated as part of a disposable unit. Crit Care Med 2006;34:1589-96. Thus, for example, cable 14 may comprise four individually insulated conductors which are surrounded by a woven conductive shield, all of which are surrounded by a suitable insulating material. Such assembly steps may, for example, include mounting a semiconductor transducer on a pyrex pedestal and thereafter securing the pedestal within a housing. Further, the repeated use and the uncertain life of the pressure transducer have made it difficult to accurately charge patients for the use of the transducer device.
