Abstract
The disclosed airflow channel for a capsule-type dried power inhaler comprises: arranging an inlet port under a capsule slot to connect with each other, and an oral sucker with an inner cavity and a suction nozzle. This invention lets air flow along straight line direction, has little limit to air suction rate, and simplifies structure to reduce cost.
Description
Technical field
The present invention relates to moving flowing mode of air-flow and air flow passage in a kind of capsule type dry powder inhaler, particularly capsule type dry powder inhaler.
Background technology
The existing Diskus that generally uses, its structure mainly comprise lid, mouthful haustorium and chassis as shown in Figure 1, 2.The chassis is provided with capsule groove, capsule lancing device and gas flow means.Described gas flow means comprises air flow inlet and air-flow rotatable cabin.Described air-flow rotatable cabin is arranged on the top setting of capsule groove and communicates with each other with the capsule groove, and described air flow inlet also is arranged at capsule groove top and links up mutually with the air-flow rotatable cabin.The mouth haustorium is provided with suction nozzle and screen cloth, and the inner chamber of mouthful haustorium is connected with air-flow rotatable cabin and the capsule groove on the chassis.The inner chamber of gas flow means and mouthful haustorium has constituted the air flow passage of capsule type dry powder inhaler.When the capsule that is positioned at the capsule groove is punctured device and punctures, by inhaler is inverted, make medicine bag fall into mouthful air-flow rotatable cabin of haustorium screen cloth top, and rely on via air flow inlet and air-flow rotatable cabin leaked-in air, make medicine bag along with air-flow rolls, medicated powder in the medicine bag is spread out from acanthopore by centrifugal force, with air communication cross screen cloth per os haustorium inner chamber, enter the oral cavity through suction nozzle again, through pharyngolaryngeal mucosa.The shortcoming of this Diskus is: because the top that air flow inlet in the gas flow means and air-flow rotatable cabin are arranged at the capsule groove, therefore air-flow is to flow into the air-flow rotatable cabin that is positioned at capsule groove top, though when re-using, be that dry powder is sucked inversion and capsule is fallen on mouthful air-flow rotatable cabin on the chassis of haustorium screen cloth top, air-flow and the capsule that entered by air flow inlet this moment are in same horizontal level, also promptly along capsular tangential inflow, again along effusive with the perpendicular direction of inflow direction, and this inhaler is to rely on this plume to go into the centrifugal force of gas in the air-flow rotatable cabin to make medicated powder inlet port chamber, this inhaler gas powder that so just makes mixes inhomogeneous, patient's amount of air drawn is big, simultaneously patient's air-breathing speed is also required very highly, therefore to be difficult to reach the child or the adult patients of higher suction velocity all not too suitable for breathe damage because of severe.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art and provide a kind of gas flow that makes smooth and easy, gas powder mix homogeneously, to the air current flow mode and the air flow passage of the little capsule type dry powder inhaler of air-breathing speed dependence.
Air current flow mode of the present invention is: described air-flow by the air flow inlet of capsule groove below flow into, behind the capsule groove, the inner chamber, the suction nozzle of per os haustorium of per os haustorium flow out again.
Described air-flow is flowed into by the air flow inlet that is positioned at capsule fluted shaft line end.
The airflow runner of capsule type dry powder inhaler of the present invention is, it comprises the inner chamber of gas flow means, mouthful haustorium and the suction nozzle of mouthful haustorium, described gas flow means comprises air flow inlet, its structural feature is: described air flow inlet is positioned at the below of capsule groove, and air flow inlet is directly linked up mutually with the capsule groove.
With the air flow inlet in the gas flow means of capsule type dry powder inhaler by in the past, by linking up mutually with the air-flow rotatable cabin that is arranged on capsule groove top, change into and it is arranged on the below of capsule groove and directly links up mutually with the capsule groove, after air-flow is entered by air flow inlet, directly enter the capsule groove, again through capsule concentrated flow inlet haustorium.Thereby make air-flow flowing in whole inhaler be the flowing of orthoscopic, medicated powder in the capsule that has been punctured is mixed with the gas of inflow is sufficient after, reach the oral cavity smoothly.Therefore has the unobstructed advantage of gas communication, the advantage not high to air-breathing rate request, also need not to set up separately the air-flow rotatable cabin simultaneously, and because the setting of air-flow rotatable cabin has strict parameter request, so its complex process, thereby can simplify the structure of inhaler greatly, reduce its manufacturing cost.
Described capsule groove is directly linked up with the screen cloth of mouthful haustorium.
This frame mode has changed the big shortcoming of medicated powder long operational time, running resistance of setting up the air-flow rotatable cabin to be brought in the past between capsule groove and screen cloth.
Described air flow inlet is positioned at the end of capsule groove.
The inner chamber of described capsule groove is cylindrical.
The capsule groove of this structure is convenient to air-flow and is produced eddy current therein, better produces centrifugal force, thereby air-flow is mixed more fully with medicated powder.
Described air flow inlet is columniform passage for inner chamber also.
The axis of described air flow inlet is coaxial with the axis of capsule groove.
The internal diameter of described air flow inlet is less than the internal diameter of capsule groove, both stepped distributions.
This structure can make air-flow that the process of an air pressure change is arranged in flow process, and make air-flow stay the sufficiently long time so that the gas powder fully mixes in the capsule groove.
In sum, the present invention has following advantage compared to existing technology:
Owing to the air flow inlet in the gas flow means of capsule type dry powder inhaler be set directly at the below of capsule groove and directly link up mutually with the capsule groove, air-flow is entered by air flow inlet after, directly enter the capsule groove, again through the capsule concentrated flow haustorium that enters the mouth.Thereby make flow the flowing for orthoscopic of air-flow in whole inhaler, medicated powder in the capsule is mixed fully with the gas of inflow, thereby has a unobstructed advantage of gas communication, not high to air-breathing rate request simultaneously, the suitable wide advantage of crowd, also need not to set up separately the air-flow rotatable cabin simultaneously, and because the setting of air-flow rotatable cabin has strict parameter request so its complex process, thereby can simplify the structure of inhaler greatly, reduce its manufacturing cost.Simultaneously because the present invention also is arranged to air flow inlet and capsule groove coaxial, inner chamber is columniform, and the structure of stepped distribution, just make air-flow that the process of an air pressure change is arranged in flow process, and make air-flow in the capsule groove, stay the sufficiently long time so that the gas powder fully mixes.
