Integrated Sensing Systems (ISSYS, www.mems-issys.com) received a utility patent (US 6,932,114) entitled “Fluid Delivery System and Method” for a drug infusion system and method of drug delivery that employs Coriolis mass flow sensors to both control and monitor the delivery of one or more drugs to a patient. With 30 claims, including features such as bubble detection and flowrate measurement, the patent applies to intravenous, intra-arterial, subcutaneous, intramuscular, intraperitoneal, and intrathecal medication delivery.
The technology has been applied for industrial use, and the first infusion product is currently under consideration at the FDA for approval.
According to ISSYS, the system that ISSYS has developed, based on the patent, can greatly reduce the number of errors seen during drug delivery by monitoring the drug dose, dose rate, volume, drug type and concentration. It can also detect occlusions or blockages in the intravenous line and sense air bubbles.
