A method for removing bodily fluid includes drawing bodily fluid that has accumulated in excess, converting the drawn fluid from bulk liquid form to aerosol form, and disposing of the aerosol via evaporation of liquid droplets and absorption and/or diffusion of vapor. Conversion from bulk liquid to aerosol may include collecting the bulk liquid fluid in a reservoir, conveying the bulk liquid bodily fluid to an atomizer, converting the bulk liquid fluid into an aerosol having ultrafine droplets, and ejecting the aerosol into a subcutaneous space for disposal via evaporation of liquid droplets and absorption and/or diffusion of vapors. The method may be performed with a subcutaneous atomizer that may be controlled locally or by an external transmitter for effecting a conversion and mist rate to keep pace with the accumulation of excess bodily fluid.

The device for diffusing volatile substances, which comprises a container (1) to house a liquid containing the volatile substances, a capillary element (2) partially housed in said container (1), a perforated element (3) through which volatile substances are diffused, and a piezoelectric element (4) in contact with said perforated element (3) and in contact with the capillary element (2), said piezoelectric element (4) causing the vibration of said capillary element (2), wherein the diffusion device also comprises an elastic element (5) on which said piezoelectric element (4) is mounted, said elastic element (5) being attached to said container (1) or to a housing (6) that surrounds said container (1). Said elastic element allows the piezoelectric element to be perfectly centered with respect to said capillary element.

A hookah device (202) which attaches to a hookah (246). The hookah device (202) comprises a plurality of ultrasonic mist generator devices (201) for generating a mist for inhalation by a user. The hookah device (202) comprises a driver device (202) which controls the mist generator devices (201) to maximize the efficiency of mist generation by the mist generator devices (201) and optimize mist output from the hookah device (202).

The liquid cartridge assembly comprises a liquid cartridge housing and a first plug fastened to each other, a liquid cartridge is disposed between the liquid cartridge housing and the first plug, the first plug is provided with a through groove communicated with the liquid cartridge, two ends of liquid guide cotton pass through the through groove to extend into the liquid cartridge, a plurality of second protrusions for squeezing the liquid guide cotton are disposed in the through groove and an air passing gap for supplementing air to the liquid cartridge is formed between adjacent second protrusions. Additional aspects and related embodiments are disclosed further herein.

The present disclosure is directed to a pre-filled container configured to store a pre-defined volume of a vaporizable liquid composition. The present disclosure is also directed to personal vaporizing devices for using such containers. In one embodiment, the pre-filled container is configured to provide a vaporizable liquid composition stored therein to an ultrasonic vaporizing component via capillary action for vaporization thereof.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.
