This is a wearable device designed to deliver drugs over a long period without using needles. It works by holding the drug in a tubular reservoir, then using a high-speed jet pump to push tiny streams of medication through the skin. A venting valve at the other end of the reservoir helps with drug expulsion. The claims specifically describe a version where the reservoir is spirally shaped and the venting valve is positioned near the jet pump.
Why it matters: Since 2008, advancements in microfluidics, miniaturized power sources, and precision manufacturing have significantly improved the feasibility of compact, reliable wearable jet delivery systems. These developments could make the high-speed transdermal pump and its integration into a wearable form factor more achievable for long-term drug administration.
