Abstract
The control apparatus of the invention comprises a feedback system to maintain the level of glucose in a diabetic within predetermined limits. Surgically implanted in the body are a means for sensing glucose levels and a means for dispensing insulin in an amount determined by the sensing mechanism. The sensing mechanism employs a chemical solution, which, like the insulin, is stored within a reservoir forming part of the surgical implant. Means are additionally provided to couple these reservoirs to the surface of the skin so as to permit their rechargings at regular time intervals. Integrated circuit technology is employed to translate an indication of an unacceptable glucose level into an automatic injection of insulin, with the electronics being of the type capable of being powered by batteries of the kind employed in pacemaker technology.
