DermaPrecise™

Dermal injection device

In development

DermaPrecise™ is a dermal injection device in development. It is a motorized injector with programmable injection depth and volume, a Peltier element for cooling the skin before injection, and interchangeable needle heads ranging from a single needle to a 16-needle (4 × 4) configuration.

The device was designed with input from dermatologists, industrial designers, and electronic and medical device engineers. It is operated through a touch screen on its docking station.

DermaPrecise™ is designed to deliver injectable substances into the dermis (intradermal), the fat layer beneath the skin (subcutaneous) or muscle (intramuscular), and to control injection depth, volume and flow rate.
