Smart overview of the Invention

The disclosed medical device component is designed for delivering infusion fluid to a patient, integrating a fluid infusion device with a physiological analyte sensor. This component comprises a base and a top cover assembly, which can be detachably connected to the base and the infusion device. The base includes a cannula for fluid delivery and a sensor to measure physiological characteristics. Additionally, an electronics assembly is incorporated to convert sensor measurements into digital data and communicate it to the infusion device.

This invention is particularly relevant for managing conditions like diabetes, where constant monitoring and medication adjustments are crucial. Portable devices, such as insulin pumps, allow patients to maintain control over their blood glucose levels by providing precise insulin delivery. The integration of sensors within the infusion set component simplifies the process by combining fluid delivery and physiological monitoring into a single unit.

The infusion device operates by using a pump system housed within a compact unit. This system typically includes a motor, fluid containment assembly, and electronics for regulating medication delivery. The sensor within the device continuously monitors physiological parameters, such as glucose levels, and transmits this data to the infusion device, enabling automatic adjustments or alerts for manual intervention.

The design of the infusion set component ensures both fluid and electrical connectivity. It features an infusion tube with integrated sensor conductors, allowing seamless communication between the sensor and the infusion device. The tubing connector is designed to penetrate a septum, facilitating the flow of medication through the cannula to the patient while maintaining electrical connectivity for sensor data transmission.

This integrated approach enhances the functionality of medical devices by combining fluid delivery with real-time physiological monitoring. It reduces the need for multiple devices, improving patient convenience and adherence to treatment protocols. The invention's versatility allows it to be adapted for various medical applications beyond diabetes management, broadening its potential impact in healthcare.
