Latest Patents
Hai Zhang holds a patent for an "Automated Qualitative Mask Fit Tester." This hand-held device is designed to establish gas mask fit integrity effectively. The automated qualitative fit tester (QLFT) utilizes a pressure source in combination with a cartridge and a nebulizer to generate aerosols that closely match the size distributions and concentrations of OSHA-approved manual units. The invention includes a cartridge that contains the aerosol solution used for testing mask integrity and is designed to recapture any solution that collects on the interior walls of the nebulizer. Additionally, the automated QLFT is equipped with a microprocessor that executes sequences in compliance with 29 CFR 1910.134 and can write to a data storage device. This innovation significantly reduces the need for manual operation, streamlining the testing process.
