Some engineering aspects of insulin delivery systems

Abstract

The characteristics of electronically controlled insulin delivery systems are presented. Early experiments with an external system have shown promise in providing improved glycemic control over conventional methods of single or multiple subcutaneous insulin injections. The encouraging results with external insulin delivery systems have led to the development and early testing in dogs of an implantable system with remote controls to permit variable insulin flow rates. A number of questions remain to be answered before widespread experimentation with external and implanted insulin delivery systems is possible. There appears to be no major development problems with the engineering aspects of such systems.
