The Rice University students have found a solution to this challenge — they have created a folding syringe called EpiWear that can be worn on an arm like a normal wrist watch.
Once an allergic person feels an attack coming, he opens the device, applies it to his thigh, disconnects the safety lock and presses the button to allow the drug to penetrate his body. This approach allows to avoid delays, which in emergency situations can lead to a person’s death.
The syringe’s design prevents any accidental triggering. It consists of three parts printed on a 3D printer. Scientists are now working to make the invention even more compact and visible in the dark.
