How do you stop the bleeding after an entire limb has been blown off?
1 Prototype is in it's compressed state. It is compact to make it easy to travel.
2 Prototype is in it's uncompressed state. It pops up and surrounds the webbing, and is ready to begin ratcheting the webbing to cut off circulation to a wounded soldiers limb.
1 The blue spring steel pieces lock the white housing from popping up, keeping the tourniquet compact.
2 To deploy the tourniquet, the user presses in on the spring steel pieces which are holding onto the ledge, and allow the inner spring to push the white housing up around the webbing.
1 The inner spring needs to overcome the ramped spring steel pieces.
2 Once the inner spring overcomes the ramped spring steel pieces, they act as locks preventing the white housing from falling down during ratcheting. the load is on the red middle piece, so the lock doesn't have to be super strong.
