CUVETTE Russian patent published in 2017 - IPC A61C13/16 

FIELD: medicine.

SUBSTANCE: cuvette for dental prostheses manufacture, containing a collapsible body, consisting of the lower and upper parts, docked and compressed between each other, with openings for outlet sprue channels. The cuvette is made of a cylindrical metal tube with removable covers in each of the parts with a possibility of their clamping and with a wall thickness that allows the two parts to be joined by means of metal pins installed in the cuvette walls. The outlet sprue channels are formed by two branch pipes, the lower ends of which are located diametrically in the connector zone with a possibility of installation in grooves created during gypsum form manufacture, adjacent to the cheek surfaces of reproduction of the wax model located in the central part of the cuvette. The upper ends of the branch pipes protruding above the cuvette are passed through the holes made in the cover of the upper part. The cover of the lower part is equipped with a stepped insert, coaxially installed with a possibility of axial movement upwards and pressure on the gypsum. The inner surfaces of the cuvette are protected against interaction with gypsum by insulation, and under the insert is an elastic insert pressed against it by a clamp with a possibility of pressure on the insert during heat treatment during plastic base polymerization.

EFFECT: simplified design of the cuvette, reduced labour costs in manufacturing and operation, increased versatility.
