Abstract:
     The present invention relates to a measuring device of quickly and accurately determining human immunoglobulin deposit ring diameter in clinical medical examination and teaching and scientific research units. It is developed according to the principle of that when a circle is synchronously tangential to two sides of a triangle and one between the two side is unit in lengh and the included angle between two sides of tangency is known, the trigonometric function of circle diameter can be solved and by combining characteristcs of immunoglobulin deposit ring. It is a special-purpose tool capable of measuring white ring-like material whose diameter is within 2cm in semi-solid material, is made of metal and consists of two measuring scales their length is 10cm-18cm at a 4deg.-9deg. included angle, and each measuring scale is equipped with a measuring foot which is controlled by a switch and can be slided at will dwing measurement, and then the different-sized circle diameters obtained by....
