Abstera

This device ensures that you don't need any needles to inject medicine into your body and to me this is the best device both for patients and physicians.

The developers says that:

Our needle-free delivery system administers a narrow stream of medication, about the size of a strand of hair, through the skin in less than half a second.

I observe that with this device every injection looks precise and complete, i think most of patient will prefer it because of it's simplicity & comfort it works as simple as 1,2,3 just load administered and discard.

It also has a nice companion app compatible with android and iOS devices and users can check real time data by using this app.

As we all know that needles cause stress and anxiety for many peoples including kids and in my opinion this device is the best solution.
