Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
One kind prevents drug from flowing backwards rubber mat formula nebulization equipment, including shell 1 referring to FIG. 1-2,1 top of shell
Outside is connected with sealing cover 2, and the top of shell 1 is fixedly connected with movable spring 3, and one end of movable spring 3 is fixedly connected with
The inside of sealing cover 2 is arranged in seal gasket 4, seal gasket 4, and the bottom of sealing cover 2 is fixedly connected with baffle 5, and sealing cover 2
Middle part fixing sleeve be connected to inhale mist pipe 6, inhale mist pipe 6 bottom be fixedly connected with atomization set 7, the top of 7 inner cavity of atomization set is fixed
It is connected with link block 8, and the bottom of atomization set 7 offers air channel 9, the bottom fixing sleeve of shell 1 is connected to air inlet pipe 10, air inlet
The top of pipe 10 is fixedly installed with gas nozzle 11.
Wherein, seal gasket 4 is the circular ring shape of middle part hollow out, and the inner wall of the outside of seal gasket 4 and sealing cover 2 is movable
Connection, can be during shell 1 and sealing cover 2 be installed, using the elasticity of seal gasket 4 itself, so that shell 1 and sealing
It can combine closely between lid 2, while also ensure the leakproofness inside shell 1, avoid the problem of oxygen leaks, from
And ensure the stability of 1 internal pressure of shell.
Wherein, baffle 5 is located at the inside of shell 1, and baffle 5 and inhaling does not contact between mist pipe 6, baffle 5 and inhale mist pipe 6 it
Between form a baffle space, can prevent medical fluid from flashing during medical liquid atomizing, while can also be in shell 1
Portion forms of short duration negative pressure cavity, and moment adsorbs medical fluid upwards, avoids the inside that medical fluid flows backward to air inlet pipe 10.
Wherein, the top of atomization set 7 is located at the inside for inhaling mist pipe 6, and the shape of 7 bottom of atomization set is isosceles trapezoid, can
With air inlet pipe 10 stop supply when, medical fluid is hurtled down along the bottom of atomization set 7, avoid medical fluid because it is long when
Between the problem of converging at gas nozzle 11 and causing suck-back.
Wherein, link block 8 is located at the underface of air channel 9, and the width value of link block 8 is less than the diameter value for inhaling mist pipe 6,
Medical fluid can be made constantly to hit link block 8 under the thrust of oxygen stream, so that the volume of medical fluid changes,
It ultimately forms mist particles and is sprayed from mist pipe 6 is inhaled.
Wherein, the top of gas nozzle 11 runs through shell 1 and extends to the underface of air channel 9, and the axle center of gas nozzle 11 and company
The center of block 8 is connect on same straight line, the oxygen that air inlet pipe 10 inputs high-speed flow can be compressed into, enhance medical fluid and hit
The dynamics for hitting link block 8, allows medical fluid quickly to form spray pattern, consequently facilitating patient carries out breathing use.
In suction apparatus in use, medical fluid to be added to the inside of shell 1 first, then sealing cover 2 is withheld in shell 1
Top, Compressive activities spring 3 is understood at the top of shell 1 at this time, and makes seal gasket 4 that slight deformation occur, so that shell 1
It is in close contact between sealing cover 2, is then passed through oxygen from air inlet pipe 10, and oxygen, when by gas nozzle 11, meeting is by gas nozzle 11
It is compressed into the tiny air-flow of high speed, and is flowed into the inside of atomization set 7 by air channel 9, while the medical fluid in atomization set 7 can be
Link block 8 is constantly hit under the thrust of high speed oxygen stream, and then breaks up medical fluid to form spray pattern, and after atomization
Medical fluid can be flowed into the mouth of patient with mist pipe 6 is inhaled, finally, due to high speed oxygen stream continually enters, the pressure inside shell 1
Can constantly it increase by force, and the medical fluid inside shell 1 can be carried out by air pressure from the inside that the bottom of atomization set 7 is compressed to atomization set 7
Atomization is hit, after the completion of patient inhales medicine, oxygen air inlet pipe 10 inside will stop supply, and 1 air pressure inside of shell will be by this time
It gradually reduces, and can temporarily constitute negative pressure cavity between baffle 5 and suction mist pipe 6, so that moment attracts medical fluid upwards, while gas nozzle 11
Neighbouring medical fluid can also hurtle down along the bottom of atomization set 7, avoid the problem of medical fluid converges in 11 top of gas nozzle for a long time,
Preventing medical fluid, there is a phenomenon where suck-backs at gas nozzle 11.
