METHOD FOR PRESERVING BONE ANATOMICAL PREPARATIONS Russian patent published in 2019 - IPC A01N1/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to preparation of anatomical preparations. Method of preserving bone anatomical preparations involves wet cleaning of bone material, drying at room temperature, degreasing, treatment in a fixing solution, drying and polishing. Fixing solution used is a transparent modernized two-component solution based on epoxy resin Art-Eco. Bone preparation is placed into the solution, completely immersing it, then the solution is degassed in the vacuum chamber. At the end of degassing, solution is heated to temperature of 45–50 °C for replacement of air with fixing solution in cavity of bone preparation. Then the bone preparation is taken out of the solution, dried and repeated if necessary, the above immersion of the preparation, degassing, heating and drying till complete absence of air bubbles from the bone preparation. Further, the first layer of the fixing solution is poured into the mold without a preparation with thickness of 0.5–1 cm, held for 3–5 hours until the solution is not completely cured, the bone preparation is placed on the first layer and the second layer of the solution is poured so that above the completely submerged preparation from above was 1–2 cm of solution. In a day, the prepared preparation is removed from the mold and allowed to dry for another two days, after which the preparation is ground and polished with a water-resistant emery paper of different granularity.

EFFECT: proposed method for preserving bone anatomical preparations enables preserving a bone preparation of any size and shape, without loss of visualization, protects from aggressive media, does not require special storage conditions for the preparation, prolongs the storage life of the preparation.
