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**.
