Medical diagnostic system

System for extraction and analysis of a component of blood in a body, said system receiving a disposable diagnostic reagent unit which exhibits a color change on sensing a predetermined condition, said system comprising:

• a. housing member including a spring actuated hammer means in said housing member for driving a lancet and a disposable lancet removably positioned on said hammer means;
• b. optical measurement means including a light source and light sensor for measuring light emanating from said source and reflected by blood reagent chemistry in said unit and having an optical characteristic proportional to the component of a liquid to be measured after transporting said liquid to said reagent;
• c. said optical measurement means also for generating an electrical signal responsive to a change of said blood reagent chemistry and therefore also to the component to be measured;
• d. microprocessor means for processing said generated electrical signal;
• e. display means responsive to said processed signal for providing a visual readout representative of the analysis on said display means in said housing member;
• and,
• f. means for removably receiving a disposable diagnostic reagent unit including said blood reagent chemistry.

Hand-held pocketable medical monitoring diagnostic system for extraction and analysis of a component of blood in a body, said system comprising:

• a. pocketable housing member including a spring actuated hammer means in said housing member for driving a means for puncturing and a disposable lancet removably positioned on said hammer means;
• b. optical measurement means including a light source and light sensor for measuring light emanating from said source and reflected by blood reagent chemistry having a color optical characteristic proportional to the component of a liquid to be measured when in contact with said liquid;
• c. said optical measurement means for generating an electrical signal responsive to a color change of said blood reagent chemistry and therefore also to the component to be measured;
• d. microprocessor means for processing said generated electrical signal;
• e. display means responsive to said electrical signal for providing a visual readout representative of the analysis on said display means in said housing member;
• f. means for removably receiving a disposable diagnostic reagent unit;
• and,
• g. disposable diagnostic reagent unit for operative engagement in said receiving means of said glucose medical monitoring diagnostic system, said unit including housing means for operatively connecting said unit to said receiving means of said system, said blood reagent chemistry supported within said housing, at least one opening in said housing means includes means for said means for puncturing to pass through and means for transporting a liquid substance to said blood reagent chemistry, means for transporting said liquid substance to said blood reagent chemistry, and aperture means through said housing for reading a portion of said blood reagent chemistry whereby said blood reagent chemistry yields a responsive optical characteristic which is read by said optical measurement means, processed by said microprocessor means, and displayed by said display means thereby yielding a numerical value useful for diagnosing a condition.
