Hand-held shirt-pocket portable medical diagnostic system for checking measurement of blood glucose, urea nitrogen, hemoglobin, blood components or other body qualities. The system includes the engagement of a disposable needle or lance probe package which carries a chemical reagent strip such as blood reacting chemistry. The system includes a pen structure having a visual readout, a microcomputer, and photosensing circuitry which measures the change of color of the blood reacting chemistry of the disposable probe package. The pen also includes a spring arrangement for actuating a needle or lance into the skin for transferring blood from a finger or other area to the chemical reagent strip. A disposable probe structure package includes configurations for transferring of the blood to the reagent strip of the reagent strip to the blood. The pen can also create a vacuum about a time period that the needle is penetrating the skin. The system includes a verification sequence of the electronics, the chemistry of an unused disposable probe package, the presence of blood sample and multiple readings to average results. The system can also be provided with provisions for storing a plurality of readings, communicating with a personal computer, and can act as an alarm and chime to indicate time periods for blood sensing.

Hand-held pocketable medical diagnostic system for extraction and qualitative analysis of a component of blood in a living body, comprising: a. housing member including an internal spring actuating means surrounding a contained core means, said spring actuating means including an actuator spring, cocking means for said actuator spring, and means for releasing said actuator spring in response to a predetermined pressure against the skin of a body to move said core means, optical measurement means contained within said housing member, said optical measurement means including a light source and a light sensor in said housing member for measuring light emanating from said source, a blood reagent chemistry between said light source and said light sensor and having an optical characteristic responsive to the component to be measured and in contact with the blood to be measured, said optical measurement means generating an electrical signal proportional to light reflectance of said blood reagent chemistry and therefore also the component of the blood to be measured, display means in said housing member responsive to said electrical signal to provide a visual readout representative of the quantitative analysis, and socket means at one end of said housing member for removably receiving a disposable probe package; b. disposable probe package shaped to be inserted into said socket means, including said blood reagent chemistry, means for supporting said blood reagent chemistry within said probe package, and a needle supported internal to said probe package below said core means and adjacent to said blood reagent chemistry; and, c. diaphragm means operatively connected to said needle and said blood reagent chemistry for causing vacuum action of said diaphragm means to transport the blood along said needle to said blood reagent chemistry for reaction therewith, thereby resulting in a color change yielding said reflectance of light which is read by said optical measurement means when said spring actuating means through said core means drives said needle through the skin.
