Title: Max Ehwald: Innovator in Osmotic Micropump Technology
Introduction
Max Ehwald is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of osmotic micropump technology, holding 2 patents that showcase his innovative approach to fluid dynamics and assay methods.
Latest Patents
Ehwald's latest patents include a method for controlling the volume flux of a liquid in an osmotic micropump and the osmotic micropump itself. The first patent describes a method that regulates the osmotically driven volume flow of solvent through a semipermeable diaphragm. This is achieved by transferring a solute that is not freely permeable through the diaphragm from a source chamber to the pump's delivery chamber. The delivery chamber is designed as a dilution chamber, allowing for a stationary osmotic gradient along the convective flow path. This invention enables the maintenance and control of the flow rate, facilitating the movement of a volume larger than the combined volume of the source and dilution chambers.
The second patent focuses on an assay method and a fluid microsystem for conducting miniaturized affinity tests in a micro-array format. This method utilizes a liquid phase containing detectable high-molecular weight soluble substances, which are concentrated in a miniaturized measuring chamber. The hydraulic effect of a high-molecular weight osmotic agent on an ultrafiltration membrane displaces the liquid phase, allowing for high detection sensitivity by removing low-molecular weight components through the membrane pores.
