Patient vital-signs automated measuring apparatus
First Claim
1. In combination in automated medical vital signs monitoring equipment, plural transducer means each providing an electrical signal representative of an associated monitored physical parameter, multiplexing means, signal processing means connecting each of said transducer means with inputs of said multiplexing means, output means connected to the output of said multiplexing means for providing a visable indication of said monitored, physical paramaters, and timing means connected to said multiplexing means for sequentially connecting said signal processing means to said output means, wherein one of said transducer means comprising blood pressure monitoring means for occluding an artery with a monotonically decreasing pressure and means for providing a signal indicative of the occluding pressure, and wherein another of said transducer means includes respiration sensing means for providing a signal indicative of respiration state, said signal processing means associated with said blood pressure monitoring means including correcting means responsive to the output of said respiration monitoring transducer means for correcting the pressure signalled by said blood pressure monitoring transducer means.

Abstract
Automated electronic medical vital-sign measuring and recording system apparatus includes plural transducers and signal processing channels for sequentially multiplexing the monitored patient characterizing physical parameter values onto an output record -- e.g., a printed tape. The system includes manual entry facilities to enter patient identification information and the like into the printed output record, and circuitry is included to treat interdependencies regarding the monitored physical characteristics.
