Pressure data acquisition device for a patient monitoring system
First Claim
1. A data acquisition device located in a first housing for use in a patient monitoring area having a patient monitoring system located therein for monitoring a patient, which patient monitoring system includes a signal processing and display device located in a second housing which is remote and independently positionable from said first housing, but still located in said patient monitoring area, and a plurality of pressure transducers adapted to be coupled to a patient, said transducers producing a plurality of patient blood pressure signals, the data acquisition device comprising:
- receiving means in said first housing for receiving signals representing blood pressure from said plurality of pressure transducers;
conditioning means, coupled to said receiving means, located in said first housing, and responsive to control signals from said signal processing and display device for controllably conditioning the signals representing blood pressure for transmission to the signal processing and display device, the pressure transducers and the conditioning means being collocated, and the conditioning means, due to being located in said first housing, being positionable independent of the signal processing and display device located in said second housing;
means for electrically coupling the pressure transducers with the conditioning means; and
bi-directional communication means for selectively coupling the conditioning means with the signal processing and display device, to provide for the transmission of said control signals from said signal processing and display device located in said second housing to said data acquisition device located in said first housing for controlling said conditioning means, and to provide for the transmission of the conditioned blood pressure signals from said first housing to the signal processing and display device in said second housing.

Abstract
A data acquisition device is disclosed for use in a patient monitoring system which includes a display device. The system also includes a pressure transducer which produces patient blood pressure signals. The data acquisition device includes terminals for receiving signals representing blood pressure from the pressure transducer. Circuitry in the data acquisition device, including multiplexers and a digital to analog converter conditions the signals representing blood pressure. The pressure transducer and the circuitry are collocated. The device also includes circuit paths for electrically coupling the pressure transducer and the conditioning circuitry. The conditioning circuitry is selectably coupled to the display to provide the conditioned signals to the display. The data acquisition device may be positioned independently of the display device.
