As shown in figs 1-9
A kind of end-expiratory positive pressure vibrated sputum elimination device, including blowing nozzle 1, airstream vibration device 2, expiratory resistance adjuster 3 and shell
Body 4, the airstream vibration device 2 include cavity 21, spool 22 and end cap 23, and the spool 22 is arranged in cavity 21, the end
Lid 23 is threadedly attached in the downside of cavity 21, and the housing 4 includes upper shell 41 and lower housing shell 42, the 21 upper end card of cavity
Close in upper shell 41, the blowing nozzle 1 is arranged on the top of upper shell 41, and the blowing nozzle 1 is connected with cavity 21, described to exhale
Vapour lock draught control mechanism 3 is arranged on the outside of cavity 21, and the expiratory resistance adjuster 3 includes mandril 31, regulating wheel 32 and annular magnetic
Iron 33, the regulating wheel 32 are arranged on 31 outer surface of mandril, and the annular magnet 33 is arranged on 31 lower end of mandril, the upper shell
41 bottoms are threadedly attached on mandril 31, and the top surface of the lower housing shell 42 is resisted against on 32 bottom surface of regulating wheel, the lower casing
42 bottom surface of body is resisted against on end cap 23.
21 both ends of cavity are respectively equipped with gas access 211 and gas vent 213, and 21 centre position of cavity is equipped with
V-type venthole 212, the spool 22, which includes bullet 221, annular iron block 222 and guide rod 223, the end cap 23, includes guide groove
231st, venthole 232 and exhaust outlet 233, the bullet 221 are arranged in V-type venthole 212, and the guide rod 223 is along guide groove
231 directions are free to slide, when the narrow vent road that air-flow is made up of V-type venthole 212 and bullet 221,22 energy of spool
Air passage is enough automatically closed, the mandril 31 is equipped with external screw thread 311, internal thread 322 is correspondingly provided with the regulating wheel 32, can
By rotating regulating wheel 32 mandril 31 can be driven to move up and down, 32 outer surface of regulating wheel is evenly distributed with anti-slop serrations 321, adjusts
Section is convenient, and the upper shell 41 is equipped with the first catch 411, and the mandril 31 is equipped with sliding slot 312, and first catch 411 is set
Put in sliding slot 312, mandril 31 is slided up and down along 312 direction of sliding slot, avoid mandril 31 from rotating, be equipped with lower housing shell 42
Second catch 421, second catch 421 is arranged on the lower section of annular magnet 33, by the second catch 421 to annular magnet 33
Displacement distance is limited, and the lower section of annular magnet 33 is connected with spring 34, and 34 other end of spring is resisted against lower housing shell
42 bottom high spots, by spring 34 to annular magnet 33 apply elastic force, when annular magnet 33 to spool 22 close to when exhale hinder
Power raises, and when annular magnet 33 is away from spool 22, expiratory resistance reduces.
Operation principle：When the narrow gas channel that air-flow is made up of V-type venthole 212 and bullet 221, gas velocity
Degree quickening causes pressure to reduce, and forces spool 22 to V-type venthole 212 close to until air passage is complete under the action of draught head
Close, after air passage is closed, since people is also persistently rising rapidly toward air blowing in blowing nozzle 1, then the intracavitary air pressure of gas access 211
Height, under the active force of air pressure, spool 22 is open rapidly, and gas channel is opened, then the intracavitary air pressure of gas access 211 is rapid
Decline, so then form the vibratory flow of air pressure height change repeatedly, intrapulmonary air pressure is caused under the action of the vibratory flow
Vibration, when rotating regulating wheel 32, due to the stop of the first catch 411, mandril 31 will not be rotated with regulating wheel 32, but
Move up and down, if mandril 31 is moved to 33 direction of annular magnet, promote annular magnet 33 close to spool 22, at this time due to valve
Annular iron block 222 on core 22 is subject to the attraction of annular magnet 33 to act on, then cause push open spool 22 air pressure rise, ring
Shape magnet 33 is nearer apart from spool 22, and the attraction of generation is bigger, causes the air pressure pushed open needed for spool 22 also higher, that is, exhales
Atmidometer is bigger, simultaneously because the effect of attraction, the time that spool 22 closes needed for air flue will also be reduced, i.e. airstream vibration frequency
Rate is accelerated, and the more big then frequency of attraction is faster；Conversely, when rotating backward regulating wheel 32, mandril 31 is retracted, and annular magnet 33 is in bullet
Spool 22 is pushed away under the action of spring 34 so that attraction reduces, and expiratory resistance reduces, and air-flow dynamic frequency reduces, during practical application,
Contracting lip is inwardly blown containing tight blowing nozzle 1, causes the vibration of spool 22, so as to produce the vibratory flow of pressure change, is formed and exhaled
The vibration change of last positive pressure, can play the role of vibrated sputum elimination.Patient can be according to personal actual conditions, by rotating regulating wheel 32
Vibration air pressure (expiratory resistance) and vibration frequency are adjusted.When needing cleaning, end cap 23 need to only be backed out, then take out valve
Core 22, can be cleaned with alcohol or clear water.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention god.
