Summary

This cross-over study of twenty five (anticipated) healthy human subjects will utilize two active control devices, and two different widths of the investigational device. One active control is representative of the usual care tourniquet applied in hospital settings. The second active control is a windlass tourniquet representative of the pre-hospital and military usual care tourniquet device. Two inch and four inch widths of the investigational device will be evaluated. The purpose of this study is to characterize and compare investigational and control tourniquet safety and efficacy. All tourniquets will be applied to the upper thigh. Efficacy data is provided by the presence or absence of popliteal flow when assessed with ultrasound. Mapping of interface pressures between the skin and the tourniquet will provide safety data. A minimum washout of five minutes will be allowed between tourniquet applications. All interventions will be applied in one visit. No follow up visit is anticipated.

Detailed description

This is a small study of 19 participants conducted over only two days. All data for this study is collected by the study. Tourniquet application: All tourniquet applications conducted with the participant seated on the edge of an exam table with one leg hanging off the side, and the leg for tourniquet application extended outward, with the mid calf resting on a support. This position permits access to the popliteal artery for ultrasonography while the investigator has access to apply the tourniquet. The lower edge of each tourniquet is aligned just above the middle of the thigh. All tourniquets are applied over the pressure mapping sensor. The sensor is slightly thicker than denim jeans. Extra care must be taken to ensure that the material of the sensor does not interfere with removing the slack from the windlass tourniquets before turning the windlass to apply final pressure. When a second windlass tourniquet is to be applied it is applied just above or proximal to the first windlass tourniquet. The windlass of each tourniquet are located as far from each other as possible. Meaning that if the windlass of the first tourniquet is the twelve o'clock position then the windlass of the second tourniquet is positioned at the six o'clock position. The strap of each tourniquet cannot slip over the windlass of the other. This 6 and 12 positioning prevents the strap of the second windlass tourniquet from slipping over the first as it is tightened. When the tape tourniquet is applied, it is elongated, stretched as it is layered over the preceding layer with at least one half over lap. The tape tourniquet used in this study is similar to, but not the same as the product called manufactured by Entrotech, called "Battle Wrap." Results similar to this study should not be expected with the "Battle Wrap" product.

Interventions

Type	Name	Description
DEVICE	Pneumatic Tourniquet	Automated pneumatic tourniquet, applied to middle upper thigh.
DEVICE	One Windlass Tourniquet	One Windlass Tourniquet 3.8 cm (1.5 inch) wide. A Special Operations Forces Tactical Tourniquet Wide (SOFTT-W) will be used for the windlass tourniquet. One windlass tourniquet will be applied to the middle upper thigh.
DEVICE	Two Windlass Tourniquets	Two Windlass Tourniquets will be applied by applying a second 3.8 cm (1.5 inch) wide windlass tourniquet immediately proximal to the first windlass tourniquet.
DEVICE	Tourniquet Tape 5 cm	Tourniquet Tape is 5 cm (2 inch) in width. Tourniquet Tape is a highly elastic transparent occlusive material that can create circumferential pressure when stretched and wrapped around a limb. The tape should be stretched and overlapped by at least half the width as it is applied. The final wrap should be applied without tension.
DEVICE	Tourniquet Tape 10 cm	Tourniquet Tape is 10 cm (4 inch) in width. Tourniquet Tape is a highly elastic transparent occlusive material that can create circumferential pressure when stretched and wrapped around a limb. The tape should be stretched and overlapped by at least half the width as it is applied. The final wrap should be applied without tension.
