Abstract
Apparatus provides an interface between a computer, various data sources such as patient monitors and a printer via the parallel printer port of a computer for use in a data management system for anesthesia. Substantially any computer may be utilized by use of the parallel printer port to provide fast and efficient inputting of data to the computer, communication with monitors and other data sources and to enable the use of the printer via the parallel printer port. The patient's vital signs and data from other data sources is supplied to the computer via the status lines of the parallel printer port while the data lines are utilized to control a processor in the apparatus with the printer disabled by reason of the absence of a strobe pulse. The apparatus includes signal processing circuitry which multiplexes a number of analog data signals and converts them to digital signals for storage and transmission to the computer upon request. RS232 type signals are also converted to TTL signals for storage and transmission to the computer upon demand. Upon the computer providing the strobe pulse, printouts of data may be provided via the printer.
