MULTI-COMPONENT INSERTION DEVICE WITH FIXING SEAL FOR OPHTHALMIC DEVICES Russian patent published in 2017 - IPC A61F9/00 A61F2/14 G02C11/00 

FIELD: medicine.

SUBSTANCE: multi-component insertion device for an ophthalmic lens includes: the first rear and the first front curved insertion elements; conductive material on one or both of the first front and first rear curved insertion elements; an electronic component attached to the conductive material; a self-fixing element, which includes a groove on the front curved insertion element, a shaped protrusion on the rear curved insertion element, made with a possibility of introduction into the groove to tightly hold the rear curved insertion element in a position relative to the front curved insertion element, thus forming a cavity between the rear curved insertion element and front curved insertion element, and a sealing element provided for in the front curved insertion element groove and being in contact with the shaped protrusion, so as to form a vacuum seal around the cavity. At that, the insertion of the profiled protrusion into the groove compresses and maintains pressure on the sealing element in the groove to form a vacuum seal around the cavity. An ophthalmic lens device comprising a multi-component insertion device, further comprises: a hermetically sealed insert-covering layer surrounding the multi-component insertion device. The sealed insert-covering layer is formed by polymerising a reaction mixture between two portions of a casting mould when the insertion device is mounted between the two portions of the casting mould.

EFFECT: application of this group of inventions will allow to expand the arsenal of technical means associated with sealing and hermetic closure of various components in energy-powered ophthalmic and biomedical devices.
