<p>The device infuses a compound subcutaneously or intradermally over an extended period of time. The delivery is from a conventional prefilled syringe with a staked cannula with the device adhered to the injection site and the syringe positioned substantially parallel to the injection site. The cannula is formed by a mechanism integral to the device to provide the cannula distal section substantially perpendicular to the syringe axis. The compound delivery is based on springs or other mechanisms. The approach offers a low cost mechanical system for the infusion of high volume, viscous compounds. The activation of the patch infuser required a few simple steps by the user. A single lever is used to trigger all device functions.</p> |
