Table driven multichannel data acquisition and display for signal monitoring
First Claim
1. A signal monitoring system including at least one parameter measuring module having a plurality of channels for acquiring respective items of physiological data, and an information processing and display station having a plurality of control keys and a display device for managing the display of said physiological data on said display device, said system comprising:
- a data link coupling said at least one parameter measuring module to said information processing and display station; and
table memory means resident with said at least one module containing a table to be downloaded over said data link to said station for controlling the operation of said station and for defining the number, functionality and visual attribututes of said control keys and data associated with each channel of the module to be displayed in said display device, whereby said information processing and display station is capable of displaying the data of each channel independently of the functions associated with the other channels once said table is downloaded to said station.

Abstract
A method and system for patient monitoring wherein data acquired by parameter measuring modules is downloaded to an information processing and display station. Table data structures resident within the modules are downloaded to the display station during initialization of the module on the link. The tables completely define the number, functionality and visual attributes of all control keys associated with each channel of the module. The tables include: text and parse tables which define the number, size, attributes and text for each key; a process table which contains a plurality of control programs which are executed by an interpreter portion of the display software in response to activations of a control key; and a channel control table which modifies the operating conditions of the channel in response to preselected control keys. A module header table is provided which defines display memory requirements of the tables for the module'"'"'s channels, and an active-module table provided by the display station maintains a list of modules active on the link and the location of the module header tables once they are downloaded.

19. A method for monitoring signals with at least one parameter measuring module and for displaying data associated with each channel of said module at an information processing and display station to which said module is coupled over a data link, said information processing and display station having a plurality of control keys and ;
- a display device, said method comprising the step of;
downloading program instructions and channel information from said module to said station during module initialization on said data link to control the operation of said station and to define the number, functionality and visual attributes of said control keys and data associated with each channel of said module to be displayed, whereby the data of each channel are displayed by said display station independently of the functions of the other channels. - View Dependent Claims (20, 21, 22, 23)

26. A method of monitoring a signal, comprising:
-
providing at least one patient parameter measuring modules located in the vicinity of a patient, said module measuring a physiological parameter of the patient and generating patient parameter data corresponding thereto, said module further including a program memory storing a set of program instructions and a set of module data to define the characteristics of said module; providing a central processing and display station located away from the vicinity of the patient, said station having a read/write memory and a processing unit for causing said station to process and display data according to program instructions and data stored in said read/write memory; transferring said patient parameter data from said module to said central processing and display station; and downloading said program instructions and module data from the program memory of said module to the read/write memory of said central processing and display station so that said station displays said patient parameter data according to said program instructions and module data downloaded to said read/write memory. - View Dependent Claims (27, 28)
