Description

The present invention relates to an ampoule unit used to atomize a liquid such as a chemical solution into a mist and eject it, a method of using the ampoule unit, and an ultrasonic vibration type mist generator.

Conventionally, there are humidifiers, beauty devices, and medical devices that use ultrasonic waves to mist a liquid into a mist and inject it. Due to the small molecular weight (particles) of the mist-ized liquid, these are expected to have the effect of flying the mist-ized liquid far away and making it easier to penetrate into the skin and the like.

In the mist formation by ultrasonic waves, it is possible to instantly turn the liquid into mist-like particles of several μm by using an ultrasonic vibrator having a plurality of fine injection holes affected by ultrasonic vibration. The size of the particles can be controlled by changing the frequency of the ultrasonic transducer. Further, the amount of mist generated can be controlled by changing the voltage and current applied to the ultrasonic vibrator. Therefore, there is an advantage that the size and the amount of particles generated can be controlled independently. In addition, there is a feature that it is not necessary to heat the liquid when it is turned into mist, and thermal deterioration can be avoided. Furthermore, when atomized saline solution is effective for alleviating symptoms such as allergic rhinitis (hay fever), mist is made to the smallest possible particle size in order to improve the absorption of the atomized liquid. It is desirable to do.

As described above, there are techniques described in Patent Document 1 and Patent Document 2 as ones utilizing mist formation by ultrasonic waves.

However, in the method of ejecting a liquid from a plurality of micropores to realize mist formation by ultrasonic waves, the components contained in the liquid are likely to clog the micropores and solidify / crystallize, resulting in clogging. Not only does it have the defect of blocking the outlet or making it difficult to eject when discharging, but it is also unsanitary. Further, even in the device used for the nebulizer treatment, the chemical solution may remain in the flow path of the chemical solution after spraying the mistized chemical solution, which causes the above-mentioned defects and is also unsanitary.

In particular, the feature of ultrasonic waves that it is not necessary to heat the liquid when mist-forming is that when the liquid to be used has the property of crystallizing and precipitating, crystals are formed in the micropores and clogging occurs. There arises a problem that fog with a desired particle size cannot be generated or fog cannot be generated at all.

Further, when an alkaline component such as physiological saline is used, in addition to clogging of the micropores due to crystallization, corrosion of the micropores and their vicinity becomes a problem. In order to avoid this, some devices restrict or prohibit the use of salt components and disinfectants.

Further, in the conventional ample containing a liquid, the physical distance from the liquid surface to the ultrasonic vibrator increases as the amount of liquid decreases, so that the liquid to be mist does not reach the ultrasonic vibrator. The problem arises that it cannot be used. For this reason, it is recommended to use it in a certain direction or it is prohibited to use it at an angle, and it may be necessary to pay attention to the restriction of use.
