Abstract
Abstract @ 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 or 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
195 words
Hand-held pocketable measurement system for extraction and analysis of a liquid in a body, comprising: a. rectangular pocketabte housing member including: spring actuated hammer means, optical measurement means including a light source, a light sensor for measuring light emanating from said source and modified by a reagent having an optical characteristic responsive to the component of the liquid to be measured when in contact with the liquid to develop an electrical signal responsive to a color change of said reagent and therefore also the component to be measured, display means responsive to said electrical signal to provide a visual readout representative of the analysis, and channel means for removably receiving a disposable diagnostic unit; and, b. disposable diagnostic unit including: a housing member with opposing tabs for engaging in said channel means, reagent means having a color optical characteristic responsive to the component of the liquid to be measured, spring mounted lance means positioned to be struck by said hammer means and pierce the body to allow fluid to flow from therein, and wick means between said lance means and said reagent means for transporting fluid flowing from within the body to said reagent means.
