Description

Fog-storage can

Technical field

The utility model relates to a kind of fog-storage cans being used cooperatively with quantitative aerosol, the especially tank structure of fog-storage can It is arranged with interface.

Background technique

Fog-storage can is the auxiliary tool for treating drug quantitative aerosol (pMDI) sucking of asthma, for storing medicine air Mist is mainly used for children asthma.Its principle be by quantitative aerosol spray medicine mist store in fog-storage can, patient from storage mist On the one hand tank Sucked medicine can increase the curative effect of pMDI, on the other hand reduce side effect.

In actual use, following problems are frequently run onto when fog-storage can:

1. after being used for multiple times, drug is attached on the inner wall of fog-storage can, and tank body is long straight barrel, is open small, inner wall is not Easy cleaning is clean；

2. the both ends of can body are arranged in the access port of quantitative aerosol and the air entry of fog-storage can, since can body is long straight tube Body, the drug of atomization be diffused into the other end from one end of cylinder during due to tank body be long and narrow, cause in tank body Air mixing is uneven, and one end concentration presented close to quantitative aerosol is high, and suction inlet end concentration is low, and when using preserving jar Multiple air-breathing is generally required, aerosol is gradually absorbed, but usually the resistance of air-breathing tank body is bigger in the backward, if aerosol concentration is distributed It is uneven, it may occur that the preceding chemical content sucked several times is lower, behind inspiratory dyspnea the case where can not sucking enough medicaments, influence to have Soakage is imitated, to influence therapeutic effect.

Summary of the invention

This practical technical problems to be solved is: providing a kind of fog-storage can, inner tank wall is easy to clean, can effectively remove tank On the other hand the attachment and deposit of internal wall reduce aerosol and enter the intracorporal resistance of tank, aerosol can be with the intracorporal sky of tank Gas is sufficiently mixed uniformly, alleviates the case where aerosol concentration is unevenly distributed along length of tank.

The technical solution of the utility model is as follows:

Fog-storage can, including tank body, suction nozzle and mask, the tank body include dividing what face was detachably connected equally along its length Upper tank body and lower tank, upper tank body outer surface are provided with quantitative aerosol interface, the aerosol channel in quantitative aerosol interface with The axis direction of tank body is vertical；

One end of the tank body is detachably connected with rear end cap, and the other end is successively connect with connection ring, suction nozzle and mask；

The quantitative aerosol interface is located at the middle position in length of tank direction；

Unidirectional valve is provided in the connection ring.

It is arranged fluted on the joint face of the upper tank body and lower tank, is set on the joint face of the lower tank and upper tank body It is equipped with fin.

The tank body is threadedly coupled with rear end cap.

The suction nozzle is funnel-shaped, and big end is connect with connection ring inside thread.

Compared with prior art, the utility model has the following beneficial effects:

1, tank body is composed of the upper tank body and lower tank detachably separated, after a period of use can tear tank body open It opens, is directly rinsed with water inner wall, cleaning effect is more preferable compared to existing monoblock type tank body (in order to avoid generating electrostatic, when cleaning It cannot be wiped, be rinsed after can only being soaked in water, the tank body of monoblock type can only intake from both ends open, cleaning effect using brush It is bad)；

2, upper tank body and lower tank joint face have certain sealing effect, connection using the form of groove cooperation fin For the compression in face by the connection ring at tank body both ends and the screw-threaded coupling of rear end cap and tank body, assembly and disassembly is convenient；

3, aerosol channel is vertical with the axis direction of tank body and is located at the middle position in length of tank direction, on the one hand, makes Aerosol enters after tank inner chamber and is diffused into the diffusion length at suction inlet end and halves, increase dispersal direction (by original unidirectional Become two-way), conducive to aerosol air uniformly mixedization in length of tank direction, (existing fog-storage can aerosol is along length of tank direction Into, and the diffusion length longest in length of tank direction, dispersal direction only one), another aspect aerosol enters tank inner chamber Afterwards since tank body section radius is much smaller than length, it can be acted on inner tank wall rapidly, continue to expand after inner tank wall reflects Dissipate, to both ends dissipation period since aerosol inceptive direction is vertical with inner wall, rear extended meeting repeatedly with inner wall effect, thus and air Uniformly mixing is squeezed, the case where aerosol concentration is unevenly distributed along length of tank is alleviated.

The structure of the ingenious tank body of the utility model is designed reasonably, facilitates the inner wall washing of tank body, has changed simultaneously quantitative Aerosol enters the angles and positions of tank inner chamber, changes the case where aerosol concentration is unevenly distributed along length of tank, is worth pushing away Extensively.
