Abstract
The utility model discloses a kind of powder spray doser, including medicine storehouse, the cavity placing powder spray medicine bag it is provided with in medicine storehouse, the cavity one end open other end is closed, the sidewall of cavity is provided with the pricker that can puncture powder spray medicine bag, the opening of cavity connects suction nozzle, is provided with the administration channel connected with cavity in suction nozzle, and the two ends cross-sectional area of described administration channel is more than middle cross-sectional area.This utility model has the advantages that due to the cross-sectional area big at both ends and small in middle of this utility model suction nozzle administration channel, and the first cylindrical portion is set in the end of distance medicine storehouse near-end, dust cloud out is made in powder spray medicine bag repeatedly to be mixed, guarantee that well-mixed medicine mist uniform fold is to the raising of focus, beneficially therapeutic effect.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of powder spray for treating respiratory tract disease
Doser.
Background technology
Respiratory tract disease is a kind of commonly encountered diseases, and along with the deterioration of air quality, the sickness rate of respiratory tract disease is more and more higher,
Especially chronic respiratory tract disease, can bring, to patient, the pain that misery index is higher.Hospitals at Present is treated chronic respiratory
Main, the most effective way of tract disease have metered dose inhalation aerosol, Foradil Aerolizer formoterol fumarate, atomized inhalation, Foradil Aerolizer formoterol fumarate
Being again powder spray, the administration apparatus of powder spray is powder spray doser.
In prior art, the notification number such as Granted publication on the 25th in Patent Office of the People's Republic of China's February in 2009 is CN 201197841Y's
Utility model patent, a kind of dust cloud inhaler described in this patent, it is by dust cap, mouth suction nozzle cover, mouth suction nozzle and chassis structure
The capsule-type dust cloud inbalation administration device become, the rotation of mouth suction nozzle cover is fastened on the bottom of mouthful suction nozzle and is connected with mouth suction nozzle substrate, and mouth is inhaled
Mouth includes gas channel, gas channel pedestal, mouth suction nozzle substrate, mouth suction nozzle rotation card, and chassis includes screen cloth, medicine bag groove, air-flow
Rotatable cabin, elastic reset thorn capsule button, thorn capsule pricker, spring, thorn capsule pricker through hole, medicine bag groove airflow hole, medicine bag tank cover plate (,
Rotating shaft, handle, bayonet lock, pin hole, base plate, chassis card hole slot and medicine bag tank cover plate card hole slot.These dust cloud inhaler suction nozzles
Administration channel is all the cylindrical channel using omnidistance cross-sectional area equal.These powder spray doser giving in suction nozzle
Medicine passage is all cylindrical, and cross-sectional area is not changed in from start to finish, and dust cloud mixed gas is sufficiently mixed and can not be played
Useful effect.
Summary of the invention
In order to overcome drawbacks described above, this utility model aims to provide a kind of powder spray doser, makes in powder spray medicine bag
Dust cloud out can be sufficiently mixed with surrounding air, by respiratory system uniform fold to focus, is beneficial to obtain relatively
Good therapeutic effect.
This utility model solves the in-problem technical scheme of prior art: a kind of powder spray doser, including medicine
Storehouse, is provided with the cavity placing powder spray medicine bag in medicine storehouse, the cavity one end open other end is closed, and the sidewall of cavity is provided with permissible
Puncturing the pricker of powder spray medicine bag, the opening of cavity connects suction nozzle, is provided with the administration channel connected with cavity, institute in suction nozzle
State the two ends cross-sectional area of administration channel more than middle cross-sectional area.Owing to the two ends cross-sectional area of administration channel is big
In middle cross-sectional area so that dust cloud mixed gas is during whole administration channel, and dynamic pressure is from little change
Greatly, then from diminishing greatly, static pressure is from diminishing greatly bigger from little change, and flowing velocity also has from slowly to soon, then turns slow to from fast
Change procedure, these changes can cause turbulent phenomenon in dust cloud mixed gas, so that dust cloud under the effect of turbulent flow
Mixed gas is thoroughly mixed to form uniform medicine mist, can obtain preferable therapeutic effect after uniform fold to focus.
As preferably, the two ends of described administration channel are round table-like, middle cylindrical.The processing of such structure is simple,
Advantageously reduce manufacturing cost.
As preferably, described administration channel distance medicine storehouse is proximally followed successively by the first cylindrical portion, the first round platform to far-end
Shape portion, the second cylindrical portion, the second truncated cone-shaped portion.First cylindrical portion be set in powder spray medicine bag dust cloud out at medicine
Mix offer place under the whirlwind effect that storehouse air inlet enters for the first time with surrounding air, the turbulent flow that can be so follow-up is filled
Mixing is divided to provide preferably basis.
As preferably, the cross-sectional area of described first cylindrical portion is equal with the cross-sectional area of cavity.The most favourable
Whirlwind rotating energy in medicine storehouse can all import the administration channel of suction nozzle.
Compared with prior art, this utility model has the advantages that
Due to the cross-sectional area big at both ends and small in middle of this utility model suction nozzle administration channel, and at distance medicine storehouse near-end
End arranges the first cylindrical portion so that in powder spray medicine bag, dust cloud out can repeatedly be mixed, it is ensured that is sufficiently mixed
Medicine mist uniform fold to the raising of focus, beneficially therapeutic effect.
Accompanying drawing explanation
Fig. 1 is a kind of structural blast schematic diagram of the present utility model；
Fig. 2 is the cross-sectional schematic of this utility model suction nozzle；
In figure: dust cap 1, the 21, second cylindrical portion the 22, first truncated cone-shaped portion of suction nozzle the 2, second truncated cone-shaped portion 23, first
