And the rate of blowing gas is not limited by this scheme.
The air passage of the air blowing nozzle 1 in the embodiment can also be designed to be concentric; and the cross-sectional area of the contact end of the blowing nozzle 1 and the vibration cavity 2 is not required.
The use method of the auxiliary discharge device for the airway endocrine in the embodiment comprises the following steps:
a user firstly starts the driving motor 5 to enable the wind wheel 3 to rotate, deeply sucks gas to the lung cavity, quickly and completely wraps the blowing nozzle 1 with lips, and then exhales the gas, wherein the time and the speed of the exhaled gas are not limited; after the air is exhaled, the air blowing nozzle 1 is moved away from the mouth, the air blowing nozzle stays for about 5 seconds to make several times of normal breathing, the treatment is repeated for about 20 times in sequence to form a group, and the effect of discharging the secretion of the air channel can be achieved after the treatment of multiple groups is repeated. After the treatment is finished, the driving motor 5 is turned off.
Example 3
As shown in fig. 1(a), (b), and (c), the device disclosed in this embodiment includes, in addition to the structures in embodiments 1 and 2, a vibration amplifying cavity 4, which can be tightly and tightly connected with the resonant cavity 2 by threads, snap, glue, ultrasonic welding, straps, or any other means, and the sectional area of one end of the connection between the vibration amplifying cavity 4 and the resonant cavity 2 is smaller than that of the other end, so that the vibration amplifying cavity 4 is an acoustic load to the resonant cavity 2, which causes the reflection of part of the sound waves transmitted thereto, thereby enhancing the intensity of the sound waves entering the lung cavity. It can be seen that the device with the vibration amplification chamber 6 added has a better effect of promoting the discharge of airway secretions than a device without the vibration amplification chamber.
In one embodiment, the outer surface of the wind wheel 3, the inner surface of the resonance tube 2 and the vibration amplifying chamber 4 are coated with a coating of an antimicrobial material having super-hydrophobic and super-oleophobic capabilities.
Therefore, the utility model discloses a device structure is comparatively simple on the one hand, on the other hand it not only is applicable to general patient, also be applicable to severe patients or children simultaneously, its application scope compares more extensively with existing device on the existing market, the device has super hydrophobic and super oleophobic ability's antibacterial material coating at 3 surfaces of wind wheel and 2 internal surface coating of resonant cavity simultaneously, can be so that the steam that the in-process of blowing produced, saliva and sputum are not at wind wheel surface and resonance pipe internal surface adhesion, and can initiatively restrain breeding of bacterium, prolong the life of this product, reduce the possibility that takes place the pollution in this product use effectively, reduce infection and gas channel damage.
The embodiment is a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and any obvious improvement, replacement or modification which can be made by those skilled in the art without departing from the essence of the present invention belongs to the protection scope of the present invention.
