Applications:
As is evidenced in an array of MMS® applications, microwave radiometry may be used as a non-invasive technique for subcutaneous thermal sensing.
“Extravasation” is the unwanted leakage of an infused fluid, such as a contrast agent or a medicinal fluid, into the tissue surrounding a patient’s blood vessel, rather than into the vessel itself. Extravasations can be caused in several ways: inappropriate needle placement, a patient’s fragile vasculature, or even a patient’s movement. The infusing cannula/needle can be pulled from the intended vessel, or accidentally pushed through the vessel wall.
Serious complications often result from extravasations, especially for pediatric patients, or in the case of use of antineoplastic fluids.
In a collaboration with Eastern Virginia Medical School (“EVMS”) in Norfolk, VA, MMS® has developed an initial system that can differentiate between an extravasation and a normal infusion. The device can simultaneously detect extravasation of very small volumes of fluid, signal an attendant, and interrupt the flow of possibly harmful intravenous agents. Consistent with neonatal and pediatric usage, an amount of approximately 0.2ml of infusion fluid was determined.
The device has been cleared by the FDA for commercial sale in the U.S. Since approval, MMS® has achieved significant miniaturization with its Monolithic Microwave Integrated Circuit (“MMIC”) technology, as well as substantial cost reduction. These developments have expanded the potential of a finalized microwave-based extravasation system, including an application for neonatal patients.
