Current development stage

 TRL3 - Hypothesis testing and initial POC is demonstrated


Dementia, nausea, cancer and sedation conditions may lead to dehydration due to inadequate intake of liquids. Subcutaneous injection, accomplished in inserting a small needle under the skin, is the preferred way to deliver liquids to dehydrated patients or patients at risk of dehydration. Senior patients may need up to 1000 ml of liquids injected.

Currently, medical professional inserts the needle to patients. With a lack of adequate training , patient's condition may deteriorate to inflammations, infections and hospitalizations. Moreover, existing needle insertion' devices are intended on small volume drug injections (about 50 ml). 

There is a need for easy and safe subcutaneous injection device intended for large quantities of fluids for dehydration conditions.

Our Innovation

The proposed solution is a handheld semi-automatic device pinching the skin to precisely insert a needle under it at the right depth and angle. The user will only need to apply a clear plastic dressing over the needle to fix it in place.

  • Portable
  • Easy to use
  • Lower risk of contaminations complications


Existing needle insertion devices are focused on small volume drug injections (about 50 ml). Their small capacity make their benefits limited . The advantage of our concept is that it’s specifically designed and intended for re-hydration.
