Description
Technical field
The present invention relates to field of medical device, especially, relate to a kind of medical nebulizer.
Background technology
Nebulizer is a kind of conventional armarium, is mainly used in treating respiratory tract disease; Its major function is that liquid drug is atomized into water smoke, makes patient directly medicine can be sucked respiratory tract, thus directly acts on respiratory tract surface, and therefore, atomization medication treatment has good therapeutic effect usually.
Current nebulizer mainly contains two kinds, and one is compressed air type nebulizer, and another kind is soniclizer; For compressed air type nebulizer, its cardinal principle is, more atmospheric gas will be had by air pump and squeeze into nebulizer, make gas by after narrow drainage channel in nebulizer, form high velocity air, this high velocity air passes through siphonage, medicinal liquid in nebulizer is sucked air-flow by capillary channel, and penetrate on baffle element with high velocity air is together sharp, baffle element splashes forms mist vapour, thus realizes atomizing effect; For soniclizer, be then produce ultrasound wave by ultrasonic transducer, make ul-trasonic irradiation on medicinal liquid, excite mist vapour.
For compressed air type nebulizer, because structure is simple, cost is lower, is therefore widely used; But its Problems existing is, when medicinal liquid is poured into after in medicinal liquid cavity, owing to usually needing to carry out atomization operation immediately, otherwise easily tumble and spill, therefore, medicinal liquid in medicinal liquid cavity often mixes inequality, causes the drug effect of atomization uneven, is unfavorable for providing superior nebulae inhalation effect.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of medical nebulizer, this medical nebulizer while atomization operation, can make the medicinal liquid in medicinal liquid cavity carry out continuing mixing, thus makes the spray film of ejection have uniform drug effect, to improve therapeutic effect.
The technical scheme that technical solution problem of the present invention adopts is: this general practice nebulizer comprises medicinal liquid cavity; Be air inlet below described medicinal liquid cavity, side is fog outlet, and top is filling opening; The bottom of described medicinal liquid cavity is provided with guide portion, offers an air-flow arrow path in described guide portion, and the inside of described air inlet with described medicinal liquid cavity is connected by this air-flow arrow path; In described guide portion, also around also offering one on the right side of described air-flow arrow path in straight spiral helicine capillary channel; Stem and the afterbody of described capillary channel are communicated with the Sheng liquid zone, bottom of described medicinal liquid cavity and the top of described air-flow arrow path respectively, and the stem side direction of this capillary channel pierces described guide portion; The upper end outlet direction of described air-flow arrow path is provided with one piece of baffle plate, and described baffle plate is provided with sputtered component, the high-velocity flow sputtering mist formation vapour that this sputtered component will spray in air-flow arrow path; Described mist vapour leads described fog outlet by described baffle plate.
As preferably, described sputtered component is made up of the sawtooth rib being shaped in described baffle plate lower surface.
As preferably, the bottom part ring of described medicinal liquid cavity is shaped with the card wire upwards extended around described guide portion, thus when medicinal liquid is rotated bottom medicinal liquid cavity, by the combing of described card wire institute, to improve the mixed effect of medicinal liquid further.
Beneficial effect of the present invention is: this medical nebulizer in use, medicinal liquid bottom medicinal liquid cavity sucks in high velocity air from described capillary channel by siphonage by the high velocity air entered in medicinal liquid cavity from described air-flow arrow path, together spray to the sputtered component on described baffle plate, and sputter mist formation vapour; In this process, because capillary channel is straight helical form, therefore, medicinal liquid is continuous rotation in lifting process, and carry out continuous rotation by the medicinal liquid that the capillary channel stem side direction that side direction pierces described guide portion is drawn bottom medicinal liquid cavity, make the medicinal liquid in medicinal liquid cavity carry out continuing mixing, thus make the spray film of ejection have uniform drug effect, to improve therapeutic effect.
Accompanying drawing explanation
Fig. 1 is an embodiment schematic diagram of this general practice nebulizer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in fig. 1, this general practice nebulizer comprises medicinal liquid cavity 1; Be air inlet 2 below described medicinal liquid cavity 1, connect with high velocity air pipeline; Side is fog outlet 4, connects rubber face mask; Top is filling opening 3; The bottom of described medicinal liquid cavity 1 is provided with guide portion 7, offers an air-flow arrow path 51 in described guide portion 7, and the inside of described air inlet 2 with described medicinal liquid cavity 1 is connected by this air-flow arrow path 51; In described guide portion 7, also around also offering one on the right side of described air-flow arrow path 51 in straight spiral helicine capillary channel 52; Stem 520 and the afterbody 521 of described capillary channel 52 are communicated with the Sheng liquid zone, bottom of described medicinal liquid cavity 1 and the top of described air-flow arrow path 51 respectively, and stem 250 side direction of this capillary channel 52 pierces described guide portion 7; The upper end outlet direction of described air-flow arrow path 51 is provided with one piece of baffle plate 6, and described baffle plate 6 is provided with sputtered component, and this sputtered component is made up of the sawtooth rib being shaped in described baffle plate 6 lower surface; This sputtered component is by the high-velocity flow of ejection in air-flow arrow path 51 sputtering mist formation vapour; Described mist vapour leads described fog outlet 4 by described baffle plate 6.
In addition, except the present embodiment, can make around described guide portion 7 card wire upwards extended in the bottom part ring of described medicinal liquid cavity 1, thus when medicinal liquid is rotated bottom medicinal liquid cavity, by the combing of described card wire institute, to improve the mixed effect of medicinal liquid further.
Above-mentioned medical nebulizer in use, medicinal liquid bottom medicinal liquid cavity 1 sucks in high velocity air from described capillary channel 52 by siphonage by the high velocity air entered in medicinal liquid cavity 1 from described air-flow arrow path 51, together spray to the sputtered component on described baffle plate 6, and sputter mist formation vapour; In this process, because capillary channel 52 is in straight helical form, therefore, medicinal liquid is continuous rotation in lifting process, and carry out continuous rotation by the medicinal liquid that capillary channel stem 520 side direction that side direction pierces described guide portion 7 is drawn bottom medicinal liquid cavity, make the medicinal liquid in medicinal liquid cavity 1 carry out continuing mixing, thus make the spray film of ejection have uniform drug effect, to improve therapeutic effect.
Above be only preferred mode of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
