Latest Patents
Among his latest innovations is the "Portable Drug Delivery Device Including Pump with Tapered Barrel." This device offers a groundbreaking solution for delivering drugs in liquid or fluid form at a constant and self-regulated rate. It features a syringe with a spring-loaded piston that operates within a reverse-tapered cylinder, allowing for effective pressurization of the drug being dispensed. Notably, the reverse taper reduces friction on the piston during dispensing, balancing the diminishing force exerted by the expanding spring. This device also incorporates a length of tubing for drug administration through a needle and a restrictor that controls the flow rate, ensuring precision in drug delivery.
Another of his significant inventions is the "Flow Controller for IV Chamber." This innovative flow controller consists of a plug that is integrally connected to an IV chamber, with a flexible tube that runs through the plug. The unique design includes a plunger rod moved by a skirt that pinches the tube to halt the flow from the chamber, thus enhancing accuracy and sterility in IV administration.
