CALCIUM CARBONATE CEMENT FOR BONE DEFECTS FILLING Russian patent published in 2017 - IPC A61L27/12 A61L27/56

Abstract RU 2620549 C2

FIELD: medicine.

SUBSTANCE: production of calcium carbonate cement for bone defects filling involves application of the calcium carbonate crystalline phase powder - calcite and liquid - 30-60% aqueous solution of magnesium phosphate, with the following component ratio, wt % calcite powder - 40-60%; 30-60% aqueous solutionof MgHPO₄⋅3H₂O and/or Mg(H₂PO₄)₂⋅4H₂O - 40-60%. In this case, the resulting material is characterized by compressive strength of at least 8 MPa, porosity of 40-60% with pore sizes up to 1000 microns, setting time of 6-12 minutes, bulk phase is calcite.

EFFECT: increased strength, reduced setting time.
