Glucose medical monitoring system

Hand-held pocketable measurement system for extraction and analysis of blood in a body, comprising:

• a. pocketable housing member including a spring actuated hammer means in said housing member, optical measurement means including a light source and a light sensor for measuring light emanating from said source and reflected by blood reagent chemistry having a color optical characteristic responsive to the component of the liquid to be measured when in contact with the liquid, said measurement means generating an electrical signal proportional to a color change of said blood reagent chemistry and therefore also to the component to be measured, display means proportional to said electrical signal to provide a visual readout representative of the analysis on a display means in said housing member, and channel means for removably receiving a disposable diagnostic unit;
• and,
• b. disposable diagnostic unit including a unit housing with opposing tabs for slidably and removably engaging said channel means, means supporting said blood reagent chemistry in said unit housing in a position to be sensed by said optical measurement means when said unit housing is engaged within said channel means, said blood reagent chemistry having said color optical characteristic responsive to the component of the liquid to be measured, spring mounted lance means in said unit housing and positioned to be struck by said hammer means, a hole in said unit housing below said lance means, said lance means moving when struck to pierce the body to allow fluid to flow therefrom, wick means between said lance means and said blood reagent chemistry for transporting said fluid flowing from within the body to said blood reagent chemistry, and red blood cell filter means for filtering of red blood cells whereby said blood reagent chemistry undergoes a color change yielding a proportional optical characteristic which is read by said optical measurement means from a back side thereof.
