UNIVERSAL MOULD FOR CREATING THREE-DIMENSIONAL MODELS OF BLOOD VESSELS Russian patent published in 2024 - IPC A61F2/06 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Casting mould for creating three-dimensional models of blood vessels with diameter of 3-13 mm, length of 5-20 mm and a wall thickness of at least 1 mm includes a linear module for obtaining three-dimensional models of unbranched blood vessels, comprising an inner and an outer part connected to form circular channels. Bifurcation module for obtaining models of branched vessels contains three adapters with internal and external parts each connected with formation of pipes. Frame of the bifurcation module is formed from parts connected by means of front and side tenons and slots with formation of a branching structure. Polymerising module for hardening of alginate hydrogel, from which models of blood vessels are made, contains a cover inserted into a connector and a piston, which includes a piston platform, a piston shaft, a sub-tip part and a set of tips. Polymerizing module is fixed with the possibility of pouring alginate hydrogel through the cutouts of the cover into the mould. Support module for maintaining stability of the universal mould is made in the form of a support. Parts of the modules are made by photopolymer 3D printing and are connected by means of pins, protrusions, guide rails and chutes with the possibility of releasing the finished model of blood vessels at the end of the hardening process.

EFFECT: providing universality of a modular mould suitable for multiple use.
