Patent No. EP3600500 (titled "Container For Cleaning The Membrane Of A Nebulizer") was filed by Vectura Delivery Devices on Mar 19, 2018. The application was issued on Jun 23, 2021.
Container for cleaning nebulizer membranes without removing them. The container fits onto the nebulizer device and holds cleaning liquid that immerses the membrane. The container has a collapsible portion that reduces volume to force the liquid into the membrane pores. This allows user-initiated cleaning by deforming the container to squirt cleaning fluid into the membrane.
