From: An iconic language for the graphical representation of medical concepts

Examples of VCM icons created by combining central pictograms, external shapes, colors and top-right pictograms. Simple physiological or pathological states are represented by combining a color that indicates the moment at which the patient state occurs, a shape that distinguishes pathological (square) and physiological (circle) states, and a central pictogram. These icons can be reused for building drug and test icons.
