:palestinian_territories: **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.** :palestinian_territories:

Please checkout the comparable (_although way more developed and tested_) [GliaX/tourniquet](https://github.com/GliaX/tourniquet) project about 3D-printing tourniquet, which are used [in the Gaza strip](https://trklou.medium.com/3d-printed-open-source-tourniquet-rationale-failure-analysis-and-proposed-next-steps-of-the-glia-97e8441b4c5a) and [in Ukraine](https://trklou.medium.com/glias-gaza-tourniquet-is-ready-for-emergency-use-in-ukraine-make-some-if-you-can-ef5f83260b7c).

## 1 - Design and usage

:warning: **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._** :warning:

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 hemostatic_) - which can be found for multipler time cheaper than an equivalent israeli bandage (_example at [medisafe.fr](https://www.medisafe.fr/secours/reanimation-survie/compression-hemostatique/pansement-compressif-sterile-10x12cm.html)_).

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 recommanded, 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

<img src="https://git.deuxfleurs.fr/distorsion/3D-printed-israeli-bandage/media/branch/main/pictures/israeli_bandage_sliced_picture.png?raw=true" alt="Image not available" height="400" />

You can print this israeli bandage lever from the [3Dfiles/israeli_bandage.stl](./3Dfiles/) 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 recommand 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](./3Dfiles/), which is fully parametric, with parameters present in the **Spreadsheet**.
