Latest Patents

One of Mulvenna's latest inventions is the Ambulatory Infusion Pump. This device is designed for the pulsed injection of predetermined dosage volumes of medication at specific intervals over an extended period. It maintains a relatively large supply of medication in a bag under pressure, releasing metered portions through an electronically controlled metering device. The metering device features a simple valve arrangement with three flexible resilient elements, ensuring a shut-off of the medication supply in case of any electrical or mechanical malfunction.

Another significant invention is the Energy Transfer Device. This device consists of a tube coiled in the form of an open helix, allowing for bending about the axis of the helix. The tube is oscillated, which alternately increases and decreases the diameter of the helix, resulting in a progressive change in axial tube velocity. This mechanism effectively squeezes and releases fluid in the conduit, facilitating fluid flow. The design includes two one-way flow control valves, enhancing the efficiency of energy transfer when the system is properly tuned.
