Abstract: Medical and surgical information, diagnostic findings, anatomical abnormalities and/or changes, and the like are rapidly and accurately recorded in a patient's chart by reproducting, duplicating or imprinting, as by stamping, an anatomical outline or graphic representation of the anatomical area involved, in the appropriate section of the patient's record, thereafter marking or noting on the reproduction or imprint,- or adjacent thereto, the findings, observations, diagnosis, size and location of lesions and the like. The imprint or reproduction can be made by means of a rubber stamp or similar ink transfer or reproducing device, which bears on one surface, the raised configuration of the anatomical outline or graphic representation thereof, which after inking can be applied to the proper section of the patient's chart. This method and device affords both time saving and extremely accurate patient record keeping for immediate and future reference.
