20210077756 | PORTABLE HALOTHERAPY DEVICE FOR AEROSOLIZING SALT - A portable halotherapy device includes a housing, a grinding chamber with a grinding blade that breaks apart dry granular salt into salt particles small enough for halotherapy, an air duct routing air to the chamber, a fluid conduit, and a high-speed exhaust fan. Ambient air flows through the air ducts into the grinding chamber to produce a first air current. Air is diverted from the first air current upward, in a second air current, through the fluid conduit and the fan. The first air current helps move dry granular salt around and against the grinding chamber, breaking it into small salt particles. The second air current is arranged relative to the first air current such that small salt particles, but not larger pieces, are carried as salt aerosol upward through the fluid conduit and fan for distribution to the environment, thereby facilitating a halotherapy session. | 2021-03-18 |
20210077757 | INHALATION COMPONENT GENERATING DEVICE, CONTROL CIRCUIT, AND CONTROL METHOD AND CONTROL PROGRAM OF INHALATION COMPONENT GENERATING DEVICE - An inhalation component generating device includes: a power supply; a load that evaporates or atomizes an inhalation component source by power from the power supply; and a control circuit that performs control based on an output of a temperature sensor. The control circuit performs: a process (a) of calculating power supply temperature on the basis of the output of the temperature sensor; and a process (b1) of determining whether the power supply temperature is in a first temperature range, and performing deterioration diagnosis on the power supply only in a case where the power supply temperature is in the range. | 2021-03-18 |
20210077758 | BREATHING ASSISTANCE APPARATUS WITH SERVICEABILITY FEATURES - A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users. | 2021-03-18 |
