Abstract:
1. A gas mist inhaler, comprising a gas supply device for supplying a gas including oxygen, carbon dioxide, or a mixed gas of oxygen and carbon dioxide, a first and a second liquid supply devices for supplying a first and a second liquids, a gas mist generation device for generating a gas mist prepared by pulverizing and dissolving the gas and the first and second liquids, the gas mist generation device including a tank for storing the first and second liquids and the gas mist, a nozzle disposed in the tank for jetting the gas mist, and a liquid discharge portion for discharging the first and second liquids stored in the tank, an inhalation member having an inhalation port for inhaling the gas mist from the gas mist generation device into a living organism, a pipe portion to be connected to the living organism and an opening for taking in outside air such that the gas mist and the outside air are inhaled into at least one of an upper air way and a lower air way of the living organism, and a liquid circulation device having a liquid circulation path, the first and second liquids stored in the tank being circulated from the liquid discharge portion to the nozzle through the liquid circulation path such that an amount of the gas dissolved in the liquid is increased through circulation thereof, wherein the tank is connected to the first liquid supply device, the nozzle is connected to the gas supply device and the second liquid supply device and disposed in a top portion of the tank, and the liquid discharge portion is disposed in a bottom portion of the tank, wherein the gas mist inhaler further comprises a liquid pressure device connected to the liquid circulation device for supplying pressurized first and second liquids to the nozzle, wherein the gas mist generation device has a gas mist discharge portion at a top portion thereof; and the gas mist with the pressurized liquids from the liquid pressure device is discharged from the gas mist discharge portion, wherein the liquid circulation path is formed of a first liquid pipe and a second liquid pipe, the first liquid pipe extending from the liquid discharge portion to the nozzle, and the second liquid pipe extending from the first liquid pipe to the liquid pressure device, wherein the liquid circulation device further includes a switching valve for switching from the first liquid pipe to the second liquid pipe or for connecting the second liquid pipe to the first liquid pipe, and wherein the tank includes an upper plate and a lower plate spaced apart from each other, each plate having pores for refining the gas mist; and a diameter of the pore of the lower plate is smaller than that of the upper plate, and the pores of the lower plate are placed out of alignment with those of the upper plate.
