FIELD: medicine.

SUBSTANCE: in order to produce the dry anatomical preparation of the heart applied is a disembowelled non-opened heart, prepared by the removal of the epicardium and subepicardial cellular tissue. Successive defatting, drying and dehydration of the organ with its following colouring are carried out. To carry out deffating the organ is placed for 3 days at room temperature into composition No 1, which consists of acetone and white spirit, taken in equal parts. The volume of composition No 1 must exceed the heart volume by 5-6 times. Then, after carrying out drying, a cavity of the deffated heart is filled with cotton or small pieces of cotton fabric. For the following dehydration the organ is placed at room temperature for 7 days in composition No 2, which represents a solution of polyacrylate varnish in acetone, taken in a volume ratio of 5:1. After that, the organ is hung also at room temperature until its dries completely. The preparation production is finished by colouring anatomical structures with oil paints, diluted with polyacrylate varnish.

EFFECT: method simplifies the production of the anatomical preparation, excluding the stage of the preparation soaking with silicate glue or liquid potassium glass, with the exclusion of application of ethylene alcohol and phenol.
