12059396 · 2024-08-13 · ·

A method for manufacturing the mechanoreception fabric for incorporation into a garment or item of apparel sets a liquid substrate to a fabric weave to produce a plurality of protuberances in graticulate array and spaced apart across a surface of the fabric. The plurality of protuberances includes pyramidal nodes, each independent and separate from other nodes, not less than 1 mm apart at the base and not more than 5 mm apart at each apex and 1.5 mm in height. Because the nodes are separated and not in contact with each other, the fabric produced is still stretchable and wearable when incorporated into an item of apparel despite the nodes having a hardness of between Shore A 60 and 80.

FLEXIBLE INNER SOCKET FOR PROVIDING INNER CIRCUMFERENCE REDUCTION TO RIGID PROSTHETIC SOCKET
20240261118 · 2024-08-08 ·

A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.
