Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
155 words
A monitor for the measurement, analysis and display of physiological data derived from a patient comprising: (a) a first transducer for measuring physiological data selected from the group consisting of pressure, temperature, gas concentration, cation and ion concentration, pH, capacitance, displacement, motion, force and flow transducers; (b) an analyzer having means for calculating selected physiological characteristics of a patient from said transducer physiological data; and alarm means; and means for displaying said measured physiological data and calculated physiological characteristics; and a manually operated hierarchical selection means for controlling the operation of said calculating and displaying means; and means for calibrating said analyzer in order to substantially eliminate measurement errors; and means to communicate threshold physiological characteristics; and means for comparing said calculated physiological characteristics against said threshold physiological characteristics and activating said alarm means when said threshold physiological characteristics are not satisfied; and (c) means for communicating said transducer measured physiological data to said analyzer.
Claim 2
Dependent Claim
155 words
A monitor for the measurement, analysis and display of physiological data derived from a patient comprising: (a) a first transducer for measuring physiological data selected from the group consisting of pressure, temperature, gas concentration, cation and ion concentration, pH, capacitance, displacement, motion, force and flow transducers; (b) an analyzer having means for calculating selected physiological characteristics of a patient from said transducer physiological data; and alarm means; and means for displaying said measured physiological data and calculated physiological characteristics; and a manually operated hierarchical selection means for controlling the operation of said calculating and displaying means; and means for calibrating said analyzer in order to substantially eliminate measurement errors; and means to communicate threshold physiological characteristics; and means for comparing said calculated physiological characteristics against said threshold physiological characteristics and activating said alarm means when said threshold physiological characteristics are not satisfied; and (c) means for communicating said transducer measured physiological data to said analyzer.
Claim 3
Dependent Claim
120 words
A monitor as described in claim 1 wherein said hierarchical selection means further comprises: (a) first manually operated selecting means for choosing a mode of operation whereby general machine or physiological functions may be selected for display, each mode having a different set of control functions, each set including specific machine operating parameters or physiological characteristics associated with said selected mode of operation; (b) second manually operated selecting means enabled upon selection of a mode, for selecting a control function from said set of control functions for said selected mode of operation; and (c) manually engaged means for energizing said calculating means for processing said physiological data into calculated physiological characteristics in response to said first and second selection means.
