H&H Medical created the TK4L as an easy-to-use tourniquet with a heavy-duty compression strap to help stop or slow blood loss in large wounds or arterial bleeding. Designed for one-handed use, the TK4L to give the user the ability to apply the maximum capable force they can generate on lower extremities.
The TK4L provides a tension fixture at one end of the strap. The added aluminum tension fixture results in the ability to apply manual force to the strap and increase the blood loss stoppage capability of the strap. By wrapping and compressing the strap around the extremity, the added compressive force increases the pressure on the limb and reduced the blood flow.
The TK4L has recently been updated with a new elastic strap that is 50% stronger than the TK4 and an enclosed tension fixture to make application easier and more secure.
