Latest Patents
Hanson's latest patents include innovative designs for diffusion cells. One of his patents describes a diffusion cell equipped with a filter screen. This design facilitates the automated removal of test aliquots of liquid from a receptor chamber. The goal is to determine percutaneous absorption through a membrane of a donor media. The system utilizes a sampling port for the removal of test aliquots via a sample tube. Additionally, a stirring device in the form of a helical coil is incorporated to ensure homogeneous mixing of the liquid within the receptor chamber. The filter screen prevents particulate matter from clogging the sample tube.
Another patent by Hanson outlines a similar diffusion cell design. This version also allows for the automated removal of test aliquots from the receptor chamber. It features a movable sample tube and a refilling tube to maintain the liquid volume in the receptor chamber. A leveling tube is included to restore the initial preset liquid volume between sampling intervals.
