Description
Technical field
The present invention relates to a kind of Diskus.
Background technology
From last century the mid-50, the inhalator of Charles Thiel inventions starts, people begin in asthma and
In the treatment of chronic obstructive disease of lung, using by medical treatment device of the inhaled drugs aerosol delivery to patient.
There is apparent advantage relative to administering mode, inhalation-type drug administrations such as oral and hypodermic injections.Due to human nasal
Chamber, bronchus and the mucomembranous surface of lung accumulate very big, a total of 23 bifurcateds of respiratory tract of human body, and adult's alveolar surface area can be high
Up to 140 square metres, alveolar wall is very thin, the densely covered a large amount of capillaries of surrounding.Drug particles can be glued with fast strikethrough alveolar wherein
Membrane tissue is directly entered blood circulation.It is small rapid-action, malicious with no intestines and stomach degradation, the first pass effect without liver, dosage
Side effect is low and suitable for advantages such as large biological molecule deliverings.Lung Sucked medicine is the lungs such as treatment asthma, chronic obstructive pneumonia
The optimal treatment mode of portion's disease, had also further expanded to treatment whole body property disease in recent years, such as diabetes, its market is huge
Greatly.
Existing suction apparatus have pressurized metered dose inhalers (Pressurized Metered Dose Inhaler,
PMDI), three kinds of sprayer (Nebulizer), Diskus (Dry Powder Inhaler, DPI) forms.PMDI needs to use
Propellant, although apply at present be it is environmental-friendly to hydrofluoroalkane of the atmospheric ozone layer without destruction as propellant,
But it still can bring greenhouse effect；And, it is necessary to which the appropriate cooperation that medicine ejection-patient sucks, otherwise inhales when using pMDI
It is very low to enter efficiency.Sprayer is the product that volume is big, non-portable, is generally only applicable to use in hospital or family.And DPI is not
Need propellant；Medicine disperses to be triggered by patient inspiration flow, and there is no cooperative effect；And large biological molecule is in dry powder
Under, its stability higher.Inhalation-type drug administration is more demanding to the aerodynamic force size of drug particles, 0.5-5 microns of aerodynamic force diameter
Between drug particles can effectively deposit to lower respiratory tract and alveolar etc., so as to effectively be absorbed by human body.More than 5 microns
Particle will deposit to oral cavity, trunnion and the upper respiratory tract；And the particle less than 0.5 micron, 90% will breathe out body with patient expiration
Outside.But the drug particles powder between 0.5-5 microns be usually easy to conglomeration, it is necessary to pharmaceutical engineering technology and inhalant it is excellent
Change design to improve the dispersiveness of drug particles.There is an important parameter when assessing the validity of mealy medicine at the time of inhalation
It is exactly fine granular ratio (Fine Particle Fraction, FPF), it is organic in the medicament ejected in its expression inhalator
The ratio in lung can be deposited to.In general, the ratio is defined as the particle fraction that aerodynamic diameter in medicament is less than 5 microns.
One medication amount for suction is generally less than 50 micrograms, is usually 25-50 micrograms.It is desirable to from inhalator
The dosage of sucking-off has higher uniformity, and for the medicine of predetermined close, the relative standard deviation (RSD) between each dosage is no
Should be more than 5%.So the medicine for needing to suck generally is made capsule by existing way.
Existing capsule Diskus is typically all single branch capsule-type, need to once be brought not to user with once changing
Just, the more capsule dry powder administration suction apparatus of existing a few moneys are there is also structure is relatively complicated, production cost relative to
Higher, suction is difficult, at the same existing more capsule Diskuses there is also the complicated filling glue of dampproof effect difference application method
Some defects of capsule inconvenience
So existing capsule Diskus is up for further perfect.
The content of the invention
The purpose of the invention is to overcome shortcoming of the prior art, there is provided and it is a kind of simple in structure, it is easy to use,
The Diskus of multiple capsules can once be loaded.
In order to achieve the above object, the present invention uses following scheme：
A kind of Diskus, includes main body, and suction nozzle is equipped with described main body one end, and energy is equipped with the main body
The medicine support of rotation, is equipped with several capsule chambers for being used to place capsule, being equipped with the main body to connect in the medicine support
The through hole of capsule chamber and suction nozzle, the piercing device for being placed on the indoor capsule of capsule can be pierced through on the body by being equipped with, in institute
State main body and be equipped with the rotary wheel device that medicine support can be driven to rotate so that capsule chamber falls into the puncture direction of piercing device.
A kind of Diskus as described above, it is characterised in that the piercing device includes sliding head, is sliding
Head one end is equipped with the pricker that can pierce through the capsule, is arranged on institute equipped with sliding slot, the slip head on the body
State in sliding slot.
A kind of Diskus as described above, it is characterised in that being equipped with the main body inner wall can reset slip head
Return unit.
A kind of Diskus as described above, it is characterised in that be equipped with the body easy to be placed into capsule chamber
The installation opening of capsule, is hinged with the housing that can close the installation opening on the body, and the piercing device is arranged on housing
On.
A kind of Diskus as described above, it is characterised in that the rotary wheel device includes driving runner, described
Driving runner is movably connected in main body by shaft, and the main body is stretched out on the driving runner top, in the medicine support periphery
Driving cog is equipped with, is equipped with sliding tooth on the driving runner, the sliding tooth is intermeshed with driving cog.
A kind of Diskus as described above, it is characterised in that filtering is equipped between the through hole and suction nozzle outlet end
Net.
A kind of Diskus as described above, it is characterised in that be arranged with dust cover in the suction nozzle outer wall.
A kind of Diskus as described above, it is characterised in that sequence corresponding with capsule chamber is equipped with the medicine support
Numeral, on the body equipped with count window.
A kind of Diskus as described above, it is characterised in that the medicine support includes turntable, and the capsule chamber is evenly distributed with
On the turntable, connection rotation axis is equipped with the turntable side, limiting stand is equipped with the outer wall of connection rotation axis end
Rank, on the body equipped with mounting hole, the main body at the mounting hole, which extends internally, connecting portion, and the mounting hole is set
In the connecting portion, spacing chuck is equipped with the connecting portion inner wall of end, the connection rotation axis is plugged on the installation
In hole, the limited step is fastened in the spacing chuck.
