Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of for treating the powder spray of chronic respiratory disease
The drug delivery device of sucking.
Background technique
Respiratory disease is a kind of common disease, and with the deterioration of air quality, the disease incidence of respiratory disease is higher and higher,
Especially chronic respiratory disease can bring the higher pain of misery index to patient.Chronic respiratory is treated in Hospitals at Present
Main, the most effective way of tract disease have metered dose inhalation aerosol, Foradil Aerolizer formoterol fumarate, atomized inhalation, Foradil Aerolizer formoterol fumarate
It is called powder spray, the administration apparatus of powder spray is powder spray drug delivery device.
In the prior art as the notification number of Granted publication on the 28th in Patent Office of the People's Republic of China's November in 2007 is CN 200980876Y
Utility model patent, a kind of dust cloud inhaler described in the patent, it is that both ends respectively have a root thorn capsule pricker and help equipped with air-flow
The capsule type inhalation aerosol powder drug delivery device of power device is made of box cover, mouth haustorium, chassis and air-flow booster, two root thorn needles point
It is not fixed in the key of chassis two sides, blister cavities and air-flow aperture constitute the air-flow booster connecting with chassis, and blister cavities is by having
The pliable material of elasticity is made.These dust cloud inhalers be essentially all powder spray anther sac is horizontal, respectively pierced at the both ends of anther sac
A medicine outlet hole out is rotated anther sac by air-flow booster, using anther sac rotation generate centrifugal force by powder spray from
Medicine outlet hole throws away to realize administration, since the medicine outlet hole of anther sac is located at the endpoint at anther sac both ends, the dust cloud of anther sac lower half portion
Agent is difficult to throw away completely under gravity, is also difficult to reach drug uniform purpose during throwing away, to can give
Administering effect brings adverse effect.
Summary of the invention
In order to overcome drawbacks described above, the present invention is intended to provide a kind of Po Nang mechanism of powder spray drug delivery device, makes powder spray
The medicine outlet hole reasonable Arrangement of anther sac, drug are in the right direction, to ensure that powder spray anther sac drug completely, uniformly, reaches for patient
Best therapeutic effect offer is effectively ensured.
The present invention solves prior art technical solution of problems: a kind of Po Nang mechanism of powder spray drug delivery device,
Medicine storehouse including built-in powder spray anther sac and the pricker through medicine storehouse inner wall, the tip of pricker is towards in medicine storehouse and being located at powder spray
At the position of anther sac, pricker is located at the other end on the outside of medicine storehouse equipped with key, and the medicine storehouse places powder spray anther sac uprightly, institute
Stating key at least has two pieces of prickers, the upper end that at least one piece of lancet tip is located at powder spray anther sac, and at least another piece
Lancet tip is located at the lower end of powder spray anther sac, and the lancet tip positioned at powder spray anther sac upper end is relative to positioned at powder spray
The lancet tip of anther sac lower end is to the left or right side biases.The shape of powder spray anther sac is general intermediate cylindrical, and both ends are in
Spherical crown shape uprightly places powder spray anther sac, does not pierce out through-hole in the upper and lower spherical cap portion of powder spray anther sac, upper through-hole is mainly used
In air inlet, lower through-hole is mainly used for drug, and such powder spray anther sac is rotated in the case where the wind-force of air inlet drives, and powder spray is in gravity
It is thrown away under effect from lower through-hole, since air is replenished in time in upper through-hole, negative pressure will not be generated in powder spray anther sac, so that powder spray
It can uniformly, fully be administered.Due to being located at the lancet tip of powder spray anther sac upper end relative on powder spray anther sac
The lancet tip of end is to the left or right side biasing, it is preferable that the lancet tip in spherical crown portion and is located on powder spray anther sac
The lancet tip in spherical crown portion is arranged on powder spray anther sac central axis under powder spray anther sac and the central axis of key up and down direction is common
The plane two sides of formation, and be located at powder spray anther sac on spherical crown portion pricker and the pricker in spherical crown portion is equal under powder spray anther sac
It is tangent with spherical crown portion inner wall, in this way, the air entered from upper through-hole can form spiral shape whirlwind, punching along powder spray anther sac inner wall
The powder spray being adhered on powder spray anther sac inner wall is hit, so that it is fallen off, it is ensured that powder spray is administered completely.
Preferably, the number of keys is two, two keys are located at the opposite two sides in medicine storehouse.It is operating in this way
When key, the active force positioned at two keys of medicine storehouse opposite sides can liquidate, and convenient for patients uses.
Preferably, the pricker configuration mode of described two keys is consistent.In this way, not only there is good interchangeability, and
And the type of accessory can be reduced, reduce manufacturing cost, ease of assembly.It can make the upper lower through-hole of powder spray anther sac can be with simultaneously
It is axially symmetric relative to powder spray anther sac, be conducive to the uniformity of administration.
Preferably, being equipped with the cavity to match with powder spray anther sac upright state in the medicine storehouse.It may insure powder in this way
Mist agent anther sac is kept upright state when rotated.
Preferably, the cavity inner wall is equipped with the air inlet of perforation, the side of air inlet inner wall axial direction and cavity
Inner wall is tangent.In this way, the air entered from air inlet can form spiral shape whirlwind along cavity inner wall, and then push powder spray medicine
Capsule quickly rotates, and quickly rotates the centrifugal force of generation for the powder spray in powder spray anther sac from powder spray medicine using powder spray anther sac
The lower through-hole of capsule is thrown away, while the powder spray thrown away can be broken up by whirlwind again and form uniform mixed gas with air, favorably
In the drug treatment effect of patient.
Preferably, be circumferentially with multiple through holes on the inner wall in the medicine storehouse, multiple through holes be located at powder spray medicine
The lancet tip of capsule upper end is in same plane.Multiple through holes on the inner wall of medicine storehouse rotate a circle in dust cloud agent capsules can be with
Wind is repeatedly given to upper through-hole, generates multiple fitful wind formula whirlwind in powder spray anther sac inner wall, it is ensured that powder spray is administered completely.
Compared with prior art, the invention has the following advantages:
Due to arrangement and the left and right biasing up and down of two pieces of prickers on key of the present invention, powder spray anther sac is upright, so that dust cloud
Agent anther sac pierce out two on through-hole, two lower through-holes be respectively symmetrically located at the upper and lower spherical crown portion of powder spray anther sac, and upper vent hole can be with
Fitful wind formula spiral shape whirlwind is repeatedly generated in powder spray anther sac, so that the powder spray anther sac Emptying Rate of drug treatment
100%, dust cloud mixed gas concentration partial deviations are less than 1%, and the self-consistent property of drug treatment effect is up to 99% in the entire course for the treatment of
More than.
