Control apparatus for the automatic treatment of diabetes
First Claim
1. Control apparatus for the automatic treatment of diabetes, comprising:
- first means for admixing a urine sample from a living body with a chemical solution, a characteristic of which with respect to light varies as a function of the molar concentration of glucose complexes present in said sample;
second means providing said chemical solution;
third means providing a source of light;
fourth means exposed to said source of light via the admixture of said first means and responsive to the light impinging thereon for generating a control signal representative of the molar concentration of said glucose complexes present;
fifth means providing a source of modified insulin of increased pH; and
sixth means responsive to said control signal for automatically injecting a predetermined amount of said modified insulin into an artery of the body to maintain the level of glucose complexes within the blood within prescribed limits;
with said first, second, third, fourth, fifth and sixth means, being adapted to be surgically implanted within the body and with said second and fifth means being replenishable with chemical solution and insulin, respectively, without the need for additional surgical procedures.

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.
