The invention relates to medical training aids. The claimed method includes preparing models of bone and cartilage structures and molds for blood vessel and thyroid models by 3D printing. A plastisol containing polyvinyl chloride is used for simulating a thyroid and blood vessels. This plastisol is poured into the molds for the blood vessel and thyroid models and held until it has cooled. A plastisol containing powdered graphite and a metal glitter for echogenicity is used for simulating lymph nodes and tumorous growths. Lengths of jute twine are laid in molds, into which a plastisol with added glitter is poured, the plastisol is held until it has cooled, and neck muscle models are cut out. A plastisol containing dyes is poured into a master neck mold to produce a skin model. The models of the muscles, vessels, thyroid, bone and cartilage structures, trachea, lymph nodes and tumorous growths are arranged in the master neck mold, into which a plastisol containing glitter is poured, the assembly is left to cool before being removed and the skin model is attached. The technical result is that the structure of the phantom more closely resembles the structure of a human thyroid.

This application relates to a breathable printed fabric and its production process. The production process includes color separation of the pattern to be printed and film preparation; fabrication of a screen and selection of a squeegee; preparation of a film screen; preparation of digital white plastisol; addition of the digital white plastisol to the film screen; and printing the digital white plastisol onto the fabric using a squeegee. During the color separation process, a corresponding grayscale value is selected based on the color distribution of the pattern to be printed to adjust the film. The grayscale value ranges from 20% to 80%. The grayscale value provides a basis for the depth of color in the pattern to be printed, using the solidity and blurriness of the halftone dots to represent the depth of color. Based on the pattern to be printed, a grayscale value corresponding to the color distribution of the pattern is selected within the 20%-80% grayscale range, allowing the film to present an effect that matches the pattern. Combined with digital white plastisol printing, the resulting fabric not only effectively displays the color distribution of the pattern but also achieves a breathable, non-film-forming effect.
