Description
Technical field
The present invention relates to a kind of therapeutic administration device, 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 in spray is sprayed by the pressure of propellant during use, 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 proper use of, sucking dose also only has 10% or so, medicine
Amount deficiency affects the treatment, and also wastes drug.90% medicament residue often results in aphtha or sound in oral cavity and larynx during 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 supply stream passes through is formed between matter sheet end, suction nozzle side corresponding with the inclined surface of soft plastic piece is provided with out
Gas port, this metered dose inhaler are equipped with flap valve in suction nozzle, can separate patient's air-breathing and the air-flow exhaled, when exhaling
Breach between soft plastic piece closes up, and air-flow does not enter in medicament storage tank, is discharged from gas outlet, so improves the use of drug
Rate reduces the waste of drug, ensures therapeutic effect.
The content of the invention
It is an object of the present invention to provide a kind of medical mouth nasal aerosol delivery devices, are set by a collection medicinal cupping bottom
The air inlet holder structure put improves, and makes to generate rotation into the air-flow in collection medicinal cupping, to carrying out into the aerosol medicament collected in medicinal cupping
Effectively package, and pass through more rational pneumatic structure so that medicine gas-flow more boundling flows, and solves at least the above
And/or defect, and the advantages of at least will be described later is provided.
The technical solution adopted by the present invention is：A kind of medical mouth nasal aerosol delivery device including collection medicinal cupping, is arranged on institute
State the suction nozzle of collection medicinal cupping upper end and the air inlet seat for being arranged on the collection medicinal cupping bottom；The lower end of suction nozzle is equipped with edge, with the collection
Medicinal cupping top forms one to medicine cavity；A check valve is equipped in described give between medicine cavity and the collection medicinal cupping；The air inlet seat is equipped with
Aerosol interface and it is multiple be in circumferentially uniformly distributed gas channel；The gas channel helically extends.The technical solution passes through
More rational pneumatic structure, while the quantitative sucking of drug is formed, effective focus drug air-flow improves the use of drug
Rate and accuracy rate, have ensured therapeutic effect.
In order to enable the air-flow that aggregation is generated through helical duct effectively passes through the interior air inlet of check valve, the check valve bag
Include an interior air inlet enclosed in a ring and a feather valve film；It is arc-shaped downwards that one is equipped in the centre that the interior air inlet encloses
To the flow-guiding surface of central reduction.
Specifically, the helical angle of the gas channel is 10 ~ 45 degree.
For the reliability for making patient's air-breathing separated with the air-flow of expiration, the quantitative sucking of drug is effectively formed, as excellent
Choosing, it is described that the interior gas outlet being in communication with the outside is equipped with to medicine cavity；The feather valve film is optional by being fixed with for the edge
It selects the first valve portion for covering the interior air inlet and may be selected to be covered in the second valve portion of the interior gas outlet, first valve portion
The inner side and outer side to medicine cavity is respectively positioned in the second valve portion.
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 rim 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 of opening, medicine gas-flow into
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 the close to the interior air inlet
Three beads and the 4th bead away from the 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 avoid patient expiration's air-flow
It is outwards straight-through, effectively reduce scattering and disappearing for drug.
In order to feather valve film carry out effective position, the second valve portion is 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 top of the edge and 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 with collection medicinal cupping, formation
One more rational one-way valve structures, the air-flow for making the air-breathing of patient and exhaling 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.
