Russia has developed a "smart" bracelet for emergency injection of insulin into the body

A scientific group from LETI (St. Petersburg State Electrotechnical University) has developed a bracelet with a microelectronic device - an array of hollow micro-needles, which was obtained by 3D printing, designed to help people with diabetes.

High demand, ruble exchange rate and logistical difficulties are among the reasons for the rise in drug prices

The basic principle of its operation is to destroy the skin with micro-needles, due to which micron-sized channels are created, through which the drug goes directly to the upper layer of the skin for further penetration into the systemic bloodstream.

"Thus, the development allows to ensure less invasiveness and duration of the procedure without the participation of medical personnel," - said the project leader, researcher of the Center for Microtechnology and Diagnostics (CI CMID) of SPbGETU "LETI" Daria Adamovich.

As explained by the developers, the introduction of the drug (up to 4 ml) into the body is carried out by a single press on the button. Micron-sized needles pierce the stratum corneum of the skin, bringing the drug to the epidermis or the upper layer of the dermis, from where it penetrates unimpeded into the systemic bloodstream. A person will not experience pain, as the needles do not reach the nerve endings. Damage to the skin is minimal, and healing occurs quickly enough, which compared to conventional injections reduces the risk of infection, as well as can be used independently and provides rapid penetration of the drug into the body.
