Transcutaneous fluid delivery system with cannula inserter assembly
The patent US12048828B2 describes a transcutaneous fluid delivery system designed for efficient and precise administration of fluids to users. The system features a base assembly that adheres to the user's skin and includes a septum and a flexible subcutaneous infusion cannula. This cannula is equipped with an outer tube containing a central lumen and an inner reinforcement coil. An inserter assembly, which is releasably coupled to the base assembly, utilizes a sharp stylet to facilitate the insertion of the cannula through the skin at a specific angle. The system also incorporates a fluid connection assembly that connects the base assembly to an external fluid source, featuring a releasable interconnect that allows for the insertion of a needle through the septum after the stylet is withdrawn.
Additional claims detail various components and configurations of the system, such as the inclusion of an adhesive on the base assembly for secure attachment to the skin, and the design of the inner reinforcement coil, which can be made from round or flat wire. The system allows for fluid flow through multiple holes in the cannula, facilitated by gaps in the reinforcement coil. The inserter assembly is equipped with a rotational drive mechanism to manage the movement of the stylet and cannula during the insertion process. Furthermore, the fluid connection assembly includes a feature that indicates when the tubing is primed with fluid, enhancing usability and ensuring proper operation. Overall, the patent outlines a comprehensive system aimed at improving the delivery of fluids transcutaneously.
