ASIC for a system for clinical objective evaluation of induced pharmacological neuromuscular blockage

Abstract

Except for the output transistor, and the force transducer, the Application Special Integrated Circuit (ASIC) described herein contains all the electronic components of a system for the objective clinical evaluation of the neuromuscular blockage produced in patients, for medical purposes, by the intravenous injection of muscle relaxing drugs. The system contains three sections: an electric stimulator for motor nerves; a section that receives the signals coming from a force transducer attached to the corresponding muscle, evaluates the relative strength of the ensuing muscular contractions and stores the results in four registers, and a section that drives a liquid crystal display.
