Description
Technical field
The present invention relates to a kind of therapeutic administration devices, more particularly to a kind of mouth and nose aerosol of auxiliary medical aerosol
Drug delivery device.
Background technology
Aerosol means that dress is encapsulated in special valve system jointly with suitable propellant for drug containing, lotion or suspension
In pressure vessel, content is sprayed by the pressure of propellant when use in spray, suck for lung or be directly sprayed onto
The preparation of cavity mucous membrane, skin and space disinfection.But quantitative aerosol is used alone to come with some shortcomings, such as using skill requirement
Height, correct usage of being grown up according to relevant statistics is only 7 ~ 8%, even if only having 10% or so if proper use of sucking dose, medicine
Amount deficiency affects the treatment, and also wastes drug.90% medicament residue often results in aphtha or sound in oral cavity and larynx when exclusive use
This is mute.Notification number is that the Chinese utility model patent of CN202036643 U discloses a kind of metered dose inhaler, including holding vessel,
Holding vessel top is provided with suction nozzle, and flap valve is equipped in suction nozzle, which is put together by the inclination of two panels soft plastic piece, this is soft
The breach that gas supply stream passes through is formed between matter sheet end, suction nozzle corresponding with the inclined surface of soft plastic piece side is provided with out
Gas port, this metered dose inhaler are equipped with flap valve in suction nozzle, can separate the air-flow of patient's air-breathing and expiration, when exhaling
Breach between soft plastic piece closes up, and air-flow does not enter in medicament storage tank, is discharged from gas outlet, improves the use of drug in this way
Rate reduces the waste of drug, ensures therapeutic effect.

First valve portion and the second valve portion are respectively positioned in the inner side and outer side to medicine cavity.The technical solution with this configuration unidirectional
Valve separates the air-flow of patient's air-breathing and expiration, forms the quantitative sucking of drug, effectively improves the utilization rate of drug, ensured and controlled
Therapeutic effect.
In order to be imported from interior air inlet to medicine cavity with improving airflow smooth, preferably, the interior air inlet is annularly set
It sets on the top of the collection medicinal cupping, a downward arc-shaped water conservancy diversion to central reduction is equipped in the centre that the interior air inlet encloses
Surface.
Specifically, the interior air inlet be in axially through；The interior air inlet is including by paracentral first bead and far
Excentric second bead；First valve portion extends from the edge and snaps into second bead.First valve portion from
The structure that extends to inner periphery of outer periphery of the interior air inlet of annular so that when medicine gas-flow from the interior air inlet into fashionable from the
Push the first valve portion at one bead open, and formed from interior air inlet to medicine cavity in the diminishing cone mouth that is open, medicine gas-flow at
Boundling enters patient's body, improves accuracy rate and utilization rate that drug reaches affected part.
Further, the interior gas outlet radially penetrates through；The interior gas outlet includes close to the of the interior air inlet
4th bead of three beads and the separate interior air inlet；Second valve portion extends from the edge and snaps into the described 4th
Bead.The closing reliability of second valve portion when structure effectively improves patient breaths, while also avoiding patient expiration's air-flow
It is straight-through outward, effectively reduce scattering and disappearing for drug.
In order to feather valve film progress effective position, the second valve portion be made effectively to be covered on interior gas outlet, preferably,
The edge is equipped with positioning column；The feather valve film is equipped with the positioning through hole of adaptation corresponding with the positioning column, described
The top for collecting medicinal cupping is equipped with the positioning counterbore of adaptation corresponding with the positioning column；The feather valve film is positioned by the positioning column
It is fixed between the edge and the top of the collection medicinal cupping.
Further, do not make the expiratory airflow of patient aerosol medication will not be driven directly to spray, avoid influencing patient from
Body or other people, the suction nozzle is additionally provided with lateral wall, and the periphery of the lateral wall is equipped with outer gas corresponding with the interior gas outlet
Mouthful.
Technical solution of the present invention advantageous effect is, by lateral approach within a feather valve film be separately positioned on to medicine cavity with
The interior gas outlet of external world's connection on the outside of medicine cavity and the inside to medicine cavity of interior air inlet that is connected to collection medicinal cupping, formation
The air-flow of one more rational one-way valve structures, the air-breathing and expiration that make patient separates, while forming the quantitative sucking of drug
Effective focus drug air-flow, improves the utilization rate and accuracy rate of drug, has ensured therapeutic effect.
