Original design of a 3D printed fully functional tourniquet. The problem with the availability of market solutions led us towards analyzing the production process of tourniquets from scratch and creating a unique proposal.

The solution was developed in consultation with Polish and Ukrainian combat-experienced paramedics, IRCC field medics, battlefield medicine instructors, as well as the UAM Center for Advanced Technologies. Tourniquets save lives, so we subjected the project to rigorous testing and in-depth verification by medical and military professionals.

It took us only two months to prepare the prototype. The final version of the prototype underwent laboratory material tests, pressure distribution tests and aging chamber tests. Based on these tests we are preparing a scientific publication documenting their results.

Mass production of the project will start soon.

In printing, avoid bright colors of filament !
3D prints must not attract attention, they are to help people in combat conditions.
If you don’t have other materials, remember to paint them with any paints.

Do not send / give anyone failed 3D prints
There is no point in donating 3D prints that those in need will not be able to use. Look out for structural weaknesses and any major distortions.

Any 3D printing material is good
Unless otherwise noted in the description, models can be 3D printed from PLA, ABS, PET-G, ASA and other printing materials.

The more, the better
If you have the ability to not only 3D print, but also assemble a finished solution from it – DO IT. Any kind of help is priceless.
