A design improvement in continuous blood sampling and analysis for glucose in rest and exercise

In the past 15 yr attempts to sample blood continuously for glucose analysis with the AutoAnalyzer (Technicon Corp.) have been reasonably successful in resting subjects. However, they have sometimes required heparinization of the subjects so as to avoid clotting in the tubes of the system. To avoid the hazards of heparinization during exercise, a method is described for sampling and analyzing blood glucose continuously with the AutoAnalyzer, using a specially designed male Luer adaptor which fits into disposable Teflon catheters.
