Respiratory system disease, along with the rising year by year of sickness rate, has increasingly becomed and has threatened human health to be worth highest attention
Disease.Fog inhalation therapy is to utilize atomising device that medicine is dispersed into mist droplet so that it is be suspended in gas, and suction is exhaled
Inhale in road and lung, thus reach to purify air flue, treat and prevent respiratory tract infection, improve the purpose of ventilatory function.Neulized inhalation
Therapy, due to the advantage such as easy to use, rapid-action, drug dose is little and systemic side effects is few, has been widely used for clinic, becomes
One of important method for current treatment of respiratory diseases.
Ultrasound atomizer is to utilize output high-frequency electrical energy after supersonic generator energising, makes bottom of gullet crystal transducer send ultrasonic
Wave sound energy, acoustic energy acts on the liquid in tank by the sound passing membrane bottom atomization tank, makes the tension force on medicinal liquid surface and inertia be subject to broken
Bad, become fine mist ejection, enter respiratory tract with patient breaths by pipeline.Ultrasonic atomizatio have local drug concentration high,
The feature such as safe, evident in efficacy, has antiinflammatory, spasmolytic, antitussive, the effect such as eliminate the phlegm.
Though ultrasonic atomizatio is widely used in clinic at present, but there is many shortcoming and defect.Two kinds of the most the most frequently used nozzles
For sucking nozzle type and mask type.Sucking nozzle type needs patient compliance to use, and patient should close lip and does slow and deep air-breathing and naturally exhale
Gas, but patient often coordinates not ideal enough and excessive air-breathing occurs, the uncomfortable reactions such as uncomfortable in chest, tachypnea occurs, and the long period closes
Lip there will be perioral numbness sense.Air-breathing and exhalation process are easily leaked gas owing to can not close lip, surveys blood oxygen saturation and compare mist
Change before sucking the lowest, do not reach effective local concentration thus affect atomizing effect.Mask type is owing to all encasing mouth and nose, therefore inhales
During gas, face shield being directed at mouth and nose, taken away again during expiration, step is relatively complicated and relatively big owing to sucking area, can make for a long time
Become the infection of oral-nasal perimeter.
Utility model content
Mainly for current ultrasonic mist device, this utility model exists that the undesirable easy appearance of patient compliance is uncomfortable in chest, tachypnea, mouth week fiber crops
Wood sense；Effectively inhaled concentration is poor, does not reaches therapeutic effect；Mouth and nose face easily occurs that infection and step are cumbersome, operate
Problem the most easily, it is provided that a kind of ultrasonic atomizing device.
This utility model is that the technical scheme that solution the problems referred to above are taked is:
A kind of ultrasonic atomizing device, including ultrasonic atomizatio body, the cavity bottom at ultrasonic atomizatio body is provided with medicine chamber, ultrasonic
The top of atomization body is provided with lid, and the bottom of lid is provided with plug, and the bottom of plug is above medicine chamber, and plug is cavity knot
The bottom of structure and plug is provided with some pores, and pore communicates with medicine chamber, is provided with through nozzle hole and oxygen leads on the sidewall of plug
Hole, the outer surface in ultrasonic atomizatio body upper part side is provided with nozzle and nozzle communicates with through nozzle hole, is provided with unidirectional in nozzle
Air valve, the upper surface at nozzle is additionally provided with valve, is provided with mask on nozzle at external port, and described medicine intracavity is provided with ultrasonic
Atomising head, the other end of ultrasonic atomizatio head is connected with external ultrasound atomizer.
Further, this utility model is provided with at external port on nozzle and sucks groove, sucks groove and is positioned at the outside of mask.
This utility model also includes oxygen hose, one end of described oxygen hose extending to ultrasonic atomizatio, and this is the most internal and communicate with oxygen through hole,
The other end of oxygen hose is connected with external oxygen tank.
This utility model is provided with handle on the top of ultrasonic atomizatio body.
Groove of sucking described in the utility model is tooth form groove.
Compared with prior art, this utility model has the advantages that
1, mask is outside, can be collected by the medicine spilt by mouth and include, then coordinate respiratory movement again to inhale in respiratory
Enter, thus reduce waste and improve valid density；
2, fix with tooth and suck mouth, then close lip, the perioral numbness that reduction of patient mental tension and overexertion are caused
There is certain effect；
3, mask area is little, does not comprise nose, beneficially patient and is normally carried out respiratory movement；
4, little mask has certain effect for alleviating the infection around snout；
5, spray nozzle device rear is connected to oxygen hose, coordinate inhalation effort oxygen and medicine can together with suck respiratory tract, tremulous pulse can be improved
Blood oxygen pressure alleviates dyspnea；
6, one-way cock has the effect controlling gas flow, and valve-closing during air-breathing, gas is along pipeline flow-direction respiratory tract；Exhale
During gas, valve is open, and the gas of exhalation can be discharged along valve openings.By contrast, exhalation process is short, and speed is fast, can be effective
Reduce the waste of medicine；
7, suck mouth and mask to react with the use of discomforts such as can reducing uncomfortable in chest, tachypnea, make patient feel relatively and loosen with comfortable；
8, medicament reservoir and to suck mouth close together, the medicine being atomized just can quickly suck, and reduces the residual in pipeline, carries
High utilization ratio of drug；
9, whole atomization process, device connect and dismantle the most simple and efficient, and are easy to clean and arrange.
As it is shown in figure 1, a kind of ultrasonic atomizing device, including ultrasonic atomizatio body 1, at the cavity bottom of ultrasonic atomizatio body 1
Being provided with medicine chamber 2, be provided with lid 3 at the top of ultrasonic atomizatio body 1, the bottom of lid 3 is provided with plug 4, the bottom of plug 4
Above medicine chamber 2, plug 4 is that the bottom of cavity structure and plug 4 is provided with some pores 12, pore 12 and medicine chamber 2
Communicate, the sidewall of plug 4 is provided with through nozzle hole 13 and oxygen through hole 14, outside side, ultrasonic atomizatio body 1 top
Surface is provided with nozzle 5 and nozzle 5 communicates with through nozzle hole 13, is provided with tooth form groove 9, sucks on nozzle 5 at external port
Groove 9 is positioned at the outside of mask 6, is provided with Non-return air valve 15 in nozzle 5, and the upper surface at nozzle 5 is additionally provided with valve 8,
At external port, it is provided with mask 6 on nozzle 5, in described medicine chamber 2, is provided with ultrasonic atomizatio head 7, the other end of ultrasonic atomizatio head 7
