Microdosing system for monitored drug delivery
The Swiss sensor manufacturer Sensirion and Fraunhofer EMFT are jointly developing an intelligent and cost-efficient microdosing system for monitored drug delivery with dimensions of only 35 x 15 x 5 mm3. The microfluidic system is based on Sensirion's one-way flow sensor LD20, capable of very quick, precise and intelligent measurement of smallest flow quantities, as well as sensitive error detection and thus counteracting, for example, cross flows and paravasation. The micro- pump of Fraunhofer EMFT is seamlessly integrated into the extended flow channel of the sensor and, despite its tiny size, still reaches flow rates of up to 1000 μl / min, depending on the pump type. With these properties, the system offers great potential as a cost-efficient, disposable component for medical dosing applications. A demonstrator is displayed at the Fraunhofer EMFT booth.
