Anatomical landmarks, proportional measurement and finger measurement are the three methods in locating points.
A Anatomical landmarks: For instance, points are located according to the distance between anterior and posterior hairline, which is taken as 12 CUN; the distance between two nipples is taken as 8 cun and so on.
B Proportional measurement: The distance between the distal end of the axillary fold to the transverse cubital crease is 9 cun The distance between the transverse cubital crease and transverse wrist crease is 12 cun.
C. finger measurement
There are middle finger measurement, thumb measurement, and four finger measurement, midline of the face , neck , chest and abdomen . The first point is Huiyin(RN1), and the last point Chengjiang (RN 24). The commonly used 10 points (among the 24) are selected and introduced.
Transverse measurement on the chest and abdomen : The distance between the two nipples is 8 cum It is used to locate the transverse distance of the points on tile chest and abdomen .
Longitudinal measurement on the chest : Points are located according to the intercostal space Longitudinal measurement on the abdomen :
The distance from the sternocostal angle (Zhongting RN16) to the umbilicus (Shenque RN 8) is 8 cun, the distance from the mbilicus to the center of the upper border of symphysis pubis is taken as 5 cun.
