DEVICE FOR MAKING A BIONIC EAR PROSTHESIS Russian patent published in 2020 - IPC A61F2/50 A61F11/04 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to a device for making a bionic ear prosthesis. Device is made from heat-resistant polymer by additive 3D printing technology. Device with thickness of 1.5 mm represents a hollow shape of the auricle of the patient, enlarged in volume by its own thickness of 1.5 mm. Mold is divided longitudinally and consists of two halves matched along guides of one half of the device. Inner surface of one of halves comprises supports with height of 2 mm for elements of hearing aid in form corresponding to negative shape of said elements. Ear lobe supports power supply with wireless charge function. In the projection of tragus there is support for microphone. In the antitragus projecting support is provided in the form of a hybrid microchip. In the coil there is support in the form of a capacitor. In Darwin's tubercle there is support in form of resistor. In the leg of the pinch there is support in form of a magnetic-vibration transducer of bone conductivity. In the connected state of the device in its upper and lower part there are holes with diameter of 3 mm, one for introduction of structural material, the second one for air outlet at injection of structural material.

EFFECT: providing a device for multiple reproduction of auricle of auricle according to a form comprising a hearing aid operating according to the principle of bone conductivity by means of digital additive technologies with application of 3D printing.
