Adrenaline Clock
Rice University students have developed a miniature folding device for self-administration of adrenaline by a person at risk for developing a life-threatening allergic reaction, designed to be worn on the wrist like a watch,
Folding in three steps, the device, called EpiWear, is a unique spring-activated system for the administration of a full dose of the drug. The developers explain that the EpiWear system, which is not suitable for use only by young children, is a promising alternative to other devices available on the market.
Prototype of EpiWear. The serial device will be smaller and more elegant.
The idea of creating a folding device was proposed by one of the authors suffering from peanut allergy and having to constantly carry an adrenaline (epinephrine) syringe, which in shape and size can be compared to a very thick ballpoint pen. This device is quite inconvenient; moreover, a few years ago, manufacturers dramatically raised its market value.
The authors hope that their development will form the basis of a new device for emergency administration of adrenaline, not only cheaper, but also causing less discomfort to users. Its device will allow you to fill in the minimum amount of adrenaline needed for injection, that is, 0.3 ml, whereas modern adrenaline syringes contain more of the drug and inject only part of it.
When unfolded, the length of the EpiWear is comparable to the length of an ordinary adrenaline syringe. In its middle part there is a drug, and at the top there is a strong spring. Releasing the fuse will allow the user to press the button at the top of the device, which in the prototype cuts the thread and releases the spring, under the pressure of which the needle is inserted into the thigh skin.

According to the authors, the EpiWear folding device ensures its safety. Since the needle and the spring are in different compartments, even if accidentally released, the spring cannot put pressure on the needle. For even greater security, you can put a case on EpiWear. In addition, the developers plan to study the question of how to turn the device into a fashion accessory. To do this, it can be produced in different colors or, for example, integrated into a wristwatch.
