Abstract
An atomizer includes a cartridge with a reservoir containing a fluid and a heating system configured to atomize the fluid into a vapor for inhalation. A respiratory indicator is configured to determine an inhalation period and an exhalation period of a patient using the atomizer. The atomizer then increases atomization of the vapor during the inhalation period and decreases atomization of the vapor during the exhalation period. An impedance sensor measures an amount of the fluid in the atomizer and deactivates atomization in response to an indication of a low fluid level.
Claims30
An atomizer, comprising:
- a cartridge configured to hold a fluid;
- an atomizer system configured to atomize the fluid in the cartridge into a vapor for inhalation;
- a biosensor including a sensor circuit that emits a first wavelength of light at tissue of a user and generates at least a first spectral response around the first wavelength of light reflected from the tissue of the user;
- and
- a processing circuit configured to:
- determine a respiration rate of the user using the first spectral response;
- determine an inhalation period and exhalation period from the respiration rate;
- and
- control the atomizer system to increase atomization of the vapor during the inhalation period and decrease atomization of the vapor during the exhalation period.
