Slishman Pressure Wraps are multitools

They help you manage a wide variety of injuries. Bleeding control is a sliver of what they offer and most will never see a drop of blood.

However, many people seem to be interested in how well they can be used as tourniquets. This is not unreasonable since control of massive hemorrhage takes precedence over all else, especially during mass casualty events.

To use our wraps to control bleeding, we recommend direct pressure first, rather than application proximal to wounds as you would apply dedicated tourniquets. For amputations, or grossly mangled limbs, wrap directly over or just proximal to injury, with subsequent wraps applied proximally to the point of arterial occlusion ONLY IF NEEDED.

Slishman Pressure Wraps alone will suffice to stop arterial flow for the majority of limbs that are 60 cm or less in circumference. For larger limbs you could stack two if needed to achieve higher pressures. This approach offers widely distributed pressure and less pain. Plus you’re more prepared for multiple injuries with two or more wraps.

We know that windlass tourniquet mechanisms are quite popular for bleeding control. So we offer the following .STL files free for download. They have been optimized for use with Slishman Pressure Wraps, but feel free to try them with other types of fabrics.

Our wraps offer a slip sleeve for one handed application, and four hook-and-loop tabs sewn mid wrap for added security and ease of application. The fabric is quite resilient as well. But if you live in a setting where our wraps are not available, hopefully these files can still help you.

Files available for download

Our patent pending windlass add on files are intended for personal use only and not for commercialization. The files attached are prototypes and they will evolve and improve over time. We recommend printing with 100% infill using a strong and high melt point plastic like PTEG or ABS. PLA will work but may warp in hot settings. If you print a windlass that breaks, please do not hold us responsible.  The risk, however, is quite low. Because Slishman Pressure Wrap fabric is thin, the twist radius is also narrow, which means users have more mechanical advantage. It also means there is less torque on the windlass. Additionally, with a direct pressure first approach, a broken windlass is less likely to cause harm. Our overarching goal with making these files available is to get them into the hands of people who need them now, rather than years from now.

1. File one offers a fairly short length windlass (104mm). You may prefer this if you have stronger hands and if you care about bulk.

2. File two is a stretched out version of file one. It offers a hex key and an oxygen tank key as well.

3. File three offers more features. Every so often you just want something that can turn a nut, or hold a nut while a bolt is advanced. The strength of this tool will depend on the type of plastic or metal you choose for your print. Like any multitool, it doesn’t replace a socket set or screw driver. But perhaps it can help you in a pinch.

4. File four is a multitool with a longer lever arm and a pivot point shifted from the center to one side.

5. File five is a thin plate that limits skin pinch and discomfort.  It isn’t critical, but it’s a bit kinder.

If you have simple modifications, or if you would like to build a custom design, we are always happy to collaborate. If you, or your company have one particular design you would like to produce, then please reach out to discuss licensing and production.

Make the Slishman Pressure Wrap part of your EDC

The wrap comes with a pouch that allows you to store band-aids, gloves and other supplies to customize your mini first aid kit.
