With uniformly, be administered fully.Owing to being positioned at the lancet tip of powder spray medicine bag upper end relative to being positioned at powder spray medicine bag upper end
The lancet tip in portion is to the left or right side biasing, it is preferable that is positioned on powder spray medicine bag the lancet tip in spherical crown portion and is positioned at powder
Under mist agent medicine bag, the lancet tip in spherical crown portion divides the common shape of central shaft being listed in powder spray medicine bag central shaft with button above-below direction
The plane both sides become, and be positioned on powder spray medicine bag the pricker in spherical crown portion and be positioned under powder spray medicine bag the pricker in spherical crown portion all with
Spherical crown portion inwall is tangent, and so, the air entered from through hole can form spiral type whirlwind along powder spray medicine bag inwall, and impact is viscous
It is attached to the powder spray on powder spray medicine bag inwall so that it is come off, it is ensured that powder spray is administered completely.
As preferably, described number of keys is two, and two buttons lay respectively at the both sides that medicine storehouse is relative.So in operation
During button, the active force of two buttons being positioned at medicine storehouse opposite sides can liquidate, and convenient for patients uses.
As preferably, the pricker configuration mode of said two button is consistent.So, not only there is good interchangeability, and
And the kind of accessory can be reduced, reduce manufacturing cost, ease of assembly.The upper lower through-hole that simultaneously can make powder spray medicine bag is permissible
Axially symmetric relative to powder spray medicine bag, be conducive to the uniformity being administered.
As preferably, in described medicine storehouse, it is provided with the cavity matched with powder spray medicine bag erectility.So may insure that powder
Mist agent medicine bag is kept upright state when rotated.
As preferably, described cavity inner wall is provided with through air inlet, the axial side of air inlet inwall and cavity
Inwall is tangent.So, the air entered from air inlet can form spiral type whirlwind along cavity inner wall, and then promotes powder spray medicine
Capsule quickly rotates, and utilizes powder spray medicine bag quickly to rotate the centrifugal force of generation by the powder spray in powder spray medicine bag from powder spray medicine
The lower through-hole of capsule throws away, and the powder spray simultaneously thrown away can be broken up by whirlwind again and form uniform mixed gas, favorably with air
Drug treatment effect in patient.
As preferably, the lower end of described cavity is blind end.So may insure that powder spray will not escape from the lower end of cavity
Go out.
Compared with prior art, this utility model has the advantages that
Owing to two pieces of prickers on this utility model button are arranged and left and right biasing up and down, powder spray medicine bag is upright so that
Powder spray medicine bag sting out two on through hole, two lower through-holes be respectively symmetrically and be positioned at powder spray medicine bag upper and lower spherical crown portion, and passage can
To produce fitful wind formula spiral type whirlwind in powder spray medicine bag, so that the powder spray medicine bag of drug treatment can obtain higher
Emptying Rate, dust cloud mixed gas concentration partial deviations are less, and in the whole course for the treatment of, drug treatment effect self-consistentency is preferable.
