Abstract: A body exercise device includes a seat portion having a seat face, a pair of left and right airbags and a pair of front and rear airbags causing the seat face of the seat portion to be left-right and front-rear inclined, and an air supply unit that supplies pressurized air to the airbags. An air supply/discharge switching unit switches between supplying air to and discharging air from the airbags, and a pressure detection unit detects pressure in the airbags. A balance determination unit, in a process of supplying air to or discharging air from the right and left or front and rear airbags according to the switching operation of the air supply/discharge switching unit, determines the left-right or front-rear balance state of the user based on a difference in pressure change in the pair of left and right airbags or the pair of front and rear airbags.

Abstract: A drug solution tank of the present invention is a drug solution tank for an ultrasonic inhaler, including a drug solution reservoir portion having an upper edge that surrounds an opening and a bottom portion formed so as to protrude downward, a flange portion formed so as to extend outward from the upper edge of the drug solution reservoir portion, and a leg portion that is continuous with the outer perimeter or lower surface of the flange portion, is formed so as to surround the drug solution reservoir portion, and extends downward past the bottom portion of the drug solution reservoir portion.
