PowderJects

PowderJects was a company that developed and marketed needle-free injection devices. The company's technology aimed to deliver liquid medications, such as vaccines, through the skin using a high-pressure stream of liquid. This method was intended to reduce patient discomfort and anxiety associated with traditional needles, and to potentially improve vaccine delivery efficiency.

The core of PowderJects' technology involved a spring-loaded mechanism that created a momentary high-pressure jet. This jet of liquid was then directed at the skin, creating a small opening through which the medication could be absorbed. The devices were designed to be disposable or reusable with disposable components, depending on the specific model.

PowderJects received significant attention and investment in the late 1990s and early 2000s, particularly for its potential applications in mass vaccination campaigns. The company collaborated with various pharmaceutical and governmental organizations to test and develop its technology. However, widespread adoption faced challenges related to regulatory approval, manufacturing costs, and user acceptance compared to established needle-based methods. The company eventually ceased operations, and its technology did not achieve broad commercial success in the medical field.
