This equilibrates the “pressure heads” of the fluid column within the conduit 38 to that of the patient's heart. An electrical connector is in communication with each pressure transducer for transmitting the signals. In the context of the present invention, a blood “pressure transducer” is a sensor capable of sensing or determining a pressure blood, such as the fluid pressure of blood within a line leading out of the body from an arterial catheter, and converting such pressure to a signal that can be communicated to a monitor/display. The present invention relates generally to pressure transducers for medical use and, more particularly, to a disposable blood pressure transducer and associated monitor interface. 4,539,998, and Re 33,518, the disclosures of both of which are hereby expressly incorporated herein by reference. As a result, the use of blood pressure measurement and monitoring may increase the likelihood that a patient can be successfully treated and/or provided with needed emergency assistance. The identifier may introduce an electrical signature to the signals that can be recognized by a signal receiving device adapted to communicate with the connector. Elcam Medical’s disposable integrated pressure transducer (DIPT) is intended for pressure monitoring in clinically invasive procedures. Furthermore, pressure data are often required by two separate monitoring devices, such as a patient monitor and a cardiac output monitor, or a patient monitor and an aortic balloon pump. With such a configuration, the method includes detecting the identifier with the monitor and adjusting signal processing accordingly. Acceptable silicon pressure sensors are commercially available from Motorola, Inc. More details on acceptable pressure transducers are disclosed in U.S. Pat. relays, FETs, transistors, switches), could also be used. OEM,ODM & multi-category buying. Invasive blood pressure transducer set A collection of devices that includes tubing, a pressure transducer(s), and other items [e.g., connectors, stopcock(s), clamps and filters] intended to be used for an invasive blood pressure measurement. 6 is a circuit schematic of a connector pin interface between the exemplary disposable medical pressure transducing device and a signal receiving device. The housing 30 actually comprises several components that are bonded or otherwise coupled together. This “dual DPT” enables pressure measurements from one arterial line to be simultaneously supplied to two separate monitoring devices (for example a patient monitor and a cardiac output monitor, or a patient monitor and an aortic balloon pump). Active or passive switches which can be electrically, mechanically, optically, or magnetically triggered (e.g. The electrical signature may be a time- or frequency-based feature. An I.V. Now with reference to FIGS. The physical makeup of the identifier may be selected from a group consisting of the following: Preferably, the electrical identifier comprises a resistance/capacitance (RC) combination that possesses a characteristic time constant. For instance, a pressure switch in the monitor connector could be triggered by connection of the two connectors, whereas connection to a different DPT would not activate the switch. No. Co., Ltd.
