Electronic devices for aerosolizing and inhaling liquid having diaphragm and a pressure sensor
An electronic device includes a hand held base assembly that includes circuitry including memory and firmware executed by a processor or microcontroller of the circuitry; and a cartridge assembly that includes memory that is read by the firmware of the handheld base assembly. The cartridge assembly and the handheld base assembly are configured to removably couple together to define the electronic device for producing an aerosol for inhalation by a person. An enclosed air passageway is defined by the cartridge assembly and by the handheld base assembly, which isolates the airflow from the electronics of the device. The enclosed air passageway extends between the opening of the mouthpiece for taking a breath and a diaphragm of the handheld base assembly, movement of the diaphragm changing the air pressure within an enclosed interior space having a pressure sensor for trigging the pressure sensor when a breath is taken.
1. An electronic device for producing an aerosol for inhalation by a person, comprising:
(a) a cartridge assembly configured to aerosolize a liquid to produce the aerosol for inhalation, the cartridge assembly comprising a memory, a mouthpiece, a liquid reservoir, and a mesh assembly comprising a mesh material and a piezoelectric material; and
(b) a handheld base assembly removably coupled with the cartridge assembly, the handheld base assembly comprising a pressure sensor and circuitry including a processor or microcontroller and firmware executed by the processor or microcontroller for actuating the mesh assembly, the processor or microcontroller being configured to read the memory of the cartridge assembly;
(c) wherein the electronic device is configured to turn on when a button on an exterior of the electronic device is depressed for a predetermined period of time; and
(d) wherein the cartridge assembly and the handheld base assembly collectively define an enclosed interior air passageway in fluid communication with the mesh material and extending between an interior space of the mouthpiece to a diaphragm arranged proximate the pressure sensor within the handheld base assembly, by which diaphragm a change in pressure in the enclosed interior air passageway is detected by the pressure sensor when a breath is drawn from the mouthpiece and the electronic device is turned on to consequently cause aerosolization.
2. The electronic device of claim 1 , wherein no electronic components of the electronic device are exposed to the enclosed interior air passageway.
3. The electronic device of claim 2 , wherein all components defining the enclosed interior air passageway are made from medical grade materials such that the electronic device is compliant with ISO 18562 and ISO 10993 standards.
