3D-printed tourniquet that cuts blood flow to an injured limb

Tourniquets can save lives but are often not available when most needed.

Sygnis’ design is based on the simple car seatbelt locking system and uses easily accessible plastic straps. Unlike traditional tourniquets which require professionally sewn Velcro or difficult-to-source omnitape, this design can be quickly assembled with a 3D printer and the free downloadable manual, meaning easy implementation, decentralized production and more lives saved in emergency situations.

    I've recently graduated from the Design Faculty at the Academy of Fine Arts in Warsaw, having previously studied at the Faculties of Physics and Chemistry of the University of Warsaw. The background of scientific education allows me to maintain an analytical approach in my design projects. Since 2014, I have been gaining professional experience working for the Polish technology company Sygnis SA. For me, design is a vocation. I believe that as designers, we should direct our gaze to regions that do not promise profit or market value. We are to search for genuine needs and answer the yearning present in each and every being, both human and not. more

    Graduated from the Academy of Fine Arts in Warsaw, I also studied at the National College of Arts and Design in Dublin. In my design practice I’m most fascinated by the dialogue between users and designers as well as object-human (or non-human) interactions. more
