(A) Photograph of Tourni-belt, a strap-and-windlass design. (B) Photograph of Tourniquet Belt, a strap-and-windlass design. (C) Photograph of ParaBelt, a ratchet design. (D) Photograph of Battle Buddy, a pulley design.

  • Four models of belt tourniquets were studied. Model designs included 1 using a pulley, 1 using a ratchet, and 2 using a windlass

  • Minimum mean time to stop bleeding

  • Maximum percentage of good composite outcome

  • Ratchet is fastest and most reliable mechanism of mechanical advantage

  • ParaBelt had good results in 75% of tests, which was significantly better than the other models.

The Economic Argument for Using Safety Scalpels

Stoker R, Davis M.
The Surgical Technologist, 401-406. September, 2015. Volume 47 No. 9. Accessed Jan 31, 2018.

  • Scalpel injuries represent an estimated 7% to 8% of all sharps injuries. They are different and more dramatic, however, than needlestick injuries, and can cause life-changing and life-threatening injuries.

  • The purchasing cost of a conventional scalpel blade should NOT be considered the actual cost of the blade.

  • The use of an appropriate safety scalpel that reduces blade exposures (and therefore risk of injury) can bring the cost of using safety scalpels below the cost of using conventional scalpel blades.

Branden D. Rosenhan, M.D. talks about the safety features and intuitive design of the PenBlade, which incorporates the use of muscle memory when using this safety scalpel.

Clinical Studies

The faster you can stop the bleeding, the higher the probability you have of saving lives. XSTAT can seal wounds in under 15 seconds using injectable, fast absorbing sponges.

  • The XSTAT device has been approved by the Food and Drug Administration and is recommended by the Committee on Tactical Combat Casualty Care (CoTCCC) to control bleeding.

  • XSTAT has been shown to be more effective than QuickClot® Combat Gauze® (CG) in a swine model of junctional hemorrhage.

  • XSTAT also is applied significantly faster than standard gauze and produced pressure throughout a wound cavity in a simulated injury using ballistic gel.

  • XSTAT-treated animals achieved hemostasis in less time and remained hemostatic longer than those treated with CG. Less blood was lost during the first 10 minutes after injury in the XSTAT group than the CG group.
