Abstract

In operation, microsensors measure patient levels of O2, pH, CO2, glucose, lactic acid by themselves or in combination with temperature sensors, blood pressure and pulse sensors, and a microchromatograph. By periodic and continuous withdrawal of microliter quantities of blood, the presence and/or concentration of various constituents of the blood, physiological fluids, urine and medication can be established. The derived data is then computer analyzed against preprogrammed equilibrium levels, and solenoid valve controls regulate the dispensing of medication through one or more intravenous connections. Continuous monitoring of acute patients is assured, and medication is supplied only when needed. This would eliminate human error and would eliminate possible overdose or underdose of medication to patients.

Automatic Feedback Instrumentation for Hospital Room Utilizing Microsensors

In operation, microsensors measure patient levels of O2, pH, CO2, glucose, lactic acid by themselves or in combination with temperature sensors, blood pressure and pulse sensors, and a microchromatograph. By periodic and continuous withdrawal of microliter quantities of blood, the presence and/or concentration of various constituents of the blood, physiological fluids, urine and medication can be established. The derived data is then computer analyzed against preprogrammed equilibrium levels, and solenoid valve controls regulate the dispensing of medication through one or more intravenous connections. Continuous monitoring of acute patients is assured, and medication is supplied only when needed. This would eliminate human error and would eliminate possible overdose or underdose of medication to patients. This feedback closed- loop concept is equally applicable to industrial process control, environmental control, agricultural field control, or any other closed-loop control system able to use microsensors.
