Abstract: A measuring apparatus for measurement of at least a portion of a patient body includes a measuring aid including a set of evenly spaced parallel lines that are divided at an intermediate parallel line into at least two sections in a direction perpendicular to the intermediate parallel line. The intermediate parallel line is a zero scale line, and each of the at least two sections is provided with individual scales of corresponding measurement units ascending from the intermediate parallel line for separately measuring discretely particular portions of the patient body. The measuring apparatus further includes a fixed medium on which the measuring aid is imprinted. The evenly spaced parallel lines are parallel in a transverse direction of the fixed medium, and the intermediate parallel line is approximately located at a middle point of the fixed medium in a longitudinal direction of the fixed medium.
