3D Printed israeli bandages

Pansement israelien imprimé en 3D (version francaise ici)

[English version automatically spell checked with minimum effort put into proofreading]

🇵🇸 Israeli bandages are a very efficient medical devices, that are used by first responders all around the world and save life each day. However we should remember that they were first conceived by the genocidal israeli army. Free Palestine. 🇵🇸

Please checkout the comparable (although way more developed and tested) GliaX/tourniquet project about 3D-printing tourniquet, which are used in the Gaza strip and in Ukraine.

Here is the printable page for this model.

1 - Design and usage

⚠️ WARNING : This bandage was designed based on existing israeli bandages, however it wasn't certified as a medical device and should thus be used based on your own jugment. ⚠️

Suggested application procedure from our limited testing :

Step 1 : Clip the lever on the compressive bandage, while holding pressure on the victim's wound (if they are conscious they can apply pressure themself)	Step 2 : Do a single turn around the victim's limb and slide the lever over the wound.	Step 3 : Do another turn around the limb and pass through the normal lever passage.
Step 4 : You can do an additional turn, and then you have to start widing the other way around the limb to flip the lever back to generate pressure.	Step 5 : Keep winding around the limb to firmly hold the lever into place.	Step 6 : Once you have finished you can simply fix the end of the bandage into a tight part of the bandage to hold it in place.

This repo is a simple proposition of a 3D-printed israeli bandage (or "lever"), that is made to be clipped right at the time of application on any normal compression bandage (preferably homeostatic) - which can be found for multiple time cheaper than an equivalent israeli bandage (there are some available for around 2€ at medisafe.fr compared to around 10€ for a comparable israeli bandage).

There is a narrow clip at the bottom of the passage of the lever, which you can use to secure it after doing a single turn around the limb of the victim, so the bandage you are using can then be used as any bought israeli bandage.

The lever can either be clipped before applying the bandage to the victim (as recommended, and shown in the above table), then sliding the lever over the wound after a single turn ; or can be added after doing the first turn. In any case, the lever should "point" toward the winding direction (thus away from the wound) so that pressure is applied when the lever is flipped back.

2 - 3D printing

You can print this israeli bandage lever from the 3Dfiles/israeli_bandage.stl file, with the "lever" part pointing up so that you don't need to use any support material.

Using default parameter the lever is quite strong and thus resilient to different printing parameters and materials. We would recommend to use a strong material like PETG rather than PLA, and not using too low of an infill ratio (> 20%).

3 - Parameters

If you want to changes the parameters of this design, you can edit the Freecad file 3Dfiles/israeli_bandage_v3.FCStd, which is fully parametric, with parameters present in the Spreadsheet.
