Shown in device for inhaling powdery substances V have a flat substantially plate 1.This plate has the perforate of diagrid shape.Here it is pilot hole 2, layout in a row is made in the hole so that the configuration or the insertion of suction pipe 3 electing property.

Suction pipe 3 has the edge of a knife 4 of a center sheet type band side knife surface at its plant front end.The part 5 that this edge of a knife tensioning vacantly on the cover film 5 that is covered with cavity 6 ' do cutting shape punctures.

Cavity 6 is the cup-shaped recess 7 of a blister pack spare 8.The dark 4mm of being about of cup and cup footpath is about 7.5mm in the inlet region.

Blister pack spare 8 is equipped with powder in many such cavitys 6.The powder of these separating devices is medicated powder 6 for instance.Represent with point-like figure in the drawings.

Cover film 5 is made of aluminium foil.Thin film be attached to blister pack spare 8 above, for instance, can be in the above with its sealing label.

Circular-shaped, concave cavity 6 edges 6 ' the position corresponding with the guide hole 2 of described plate 1 when being contained in blister pack spare 8 usefulness mode easy to use on the plate 1 that the mask effect is seemingly arranged.

So just can insert and take out suction pipe 3 and it is moved on to next guide hole 2, take medicated powder 9 by amount with the accurate dosage that measured.Like this, can correspondingly inhale the drug delivery powder by suction pipe 3 to the predetermined area.For this reason, suction pipe 3 has a mouthpiece opening 10 at its other end.

For medicated powder is flowed, mouthpiece opening 10 is communicated with around the edge of a knife 4 that leads to suction pipe by inhaling medicine passage 11.So just can not have remaining medicated powder ground and inhale empty cavity 6.

For making the medicated powder circulation, inhale medicine passage 11 and be communicated with transversal ventilation mouth 12.This vent leads to the outer surface of suction pipe 3, provides extra air-flow to the band powder central authorities primary air of inhaling empty cavity 6.But vent is positioned at the outside wall surface of decorporating backward from the actual district that holds a writing brush or pen-write of suction pipe 3, and specially is provided with from the outwardly directed strip shape body of vent, thereby makes the unlikely transversal ventilation mouth 12 of blocking of the finger that holds a writing brush or pen-write.In addition, the district that holds a writing brush or pen-write on the outside wall surface is coarse so that strengthen the ability of holding with a firm grip, specifically, is provided with coarse annular cutting.

Suction pipe 3 is installed on the blister pack spare 8.Adaptor 13 carries out plug-in mounting as a suitable connecting plate.This adaptor extends along an edge 14 of blister pack spare 8, and is installed on it.This edge is that profile is the narrow limit or the horizontal edge of rectangular blister pack spare 8.The reference number on another narrow limit is 15.

The detachable suction pipe 3 that carries out clamping by adaptor 13 is installed in the semi-housing shape bracket 16 of adaptor 13.This is a kind of staple joint.This joint by colulus 16 ', 16 " constitute this two coluluses embowment and have identical profile.Described two coluluses are arranged apart from each other in the space, preferably are positioned at two folding corner regions at an edge 14, open towards the plane of plate 1.

Although provide two coluluses 16 ', 16 ", the colulus 16 of also available adaptor 13 supports 16 ' to suction pipe 3 only its mouthpiece end in the drawings left-hand side do to be convenient to the externally-hanging type clamping of gripping.Therefore, " what surround is in order to suction pipe 3 be inserted on that end in the mouth, form mouthpiece opening 10, be substantially cylindrical shape and recessed outer wall section by colulus 16.This is the custom to using the right hand and sinistral people to satisfy its use or be installed simultaneously just.

Also can make the edge of a knife end that is clipped in right side or left side or the edge of a knife 4 in both cases all near colulus 16 ', 16 " the space medial surface can work to have the impact protection all the time.Be positioned at the edge of a knife 4 tips 4 of central authorities ' even can put in the inside of corresponding colulus slightly.The mouthpiece recess is as the axial retention stop portion that is clipped in suction pipe 3 wherein.Corresponding colulus 16 ' or 16 " the inboard be used interchangeably.

Adaptor 13 is contained on the blister pack spare 8 by slipping into formula plug-in mounting joint.Relevant structure can especially clearly be indicated in Figure 18-21.Slipping into formula plug-in mounting joint is a drop-center 17 in the ingredient of blister pack spare one side.This groove leads to edge 14.The wall material that forms groove in drop-center 17 zones is got from the U font of flat covering 18 projections with regard to its section, and covering forms blister pack spare 8 and dark in the above the pressure or horizontal extrusion recess 7 substantially, makes it to same direction projection.

The body of U-shaped wall and two

coluluses

19,20 connect with mold form.Colulus is outstanding outside the back 21 of adaptor 13 horizontal stripes 22.

Colulus

19,20 connects the end regions overlap joint of side in both sides up and down with blister pack spare 8 on preposition.The bottom land 23 of drop-center 17 and groove side 24 are in the U-shaped interpolation slit 25 that is formed by two

coluluses

19,20 in this respect.The U font has orientation.Can prevent to rotate.

Keep to the side 14 front end of following colulus 20 is convergent contour towards interpolation slit 25.This respective front ends to drop-center 17U shape wall has the effect of centering.Section is that the U-shaped limbs of U-shaped have 45 ° of suitable chamferings on U-shaped web and the colulus 20.Stretch into the U-shaped space of colulus 20 to the rectangle section part of last colulus 19 and reserve a slit to form an interpolation slit 25.

The front end that suspends of colulus 19 is convexity with respect to blister pack spare 8 planes in this plane on the finger-like.The one spill end 27 that connects that is positioned at drop-center 17 the inners is contained in the front that connects round 26.

The end of following colulus 20U shape limbs and the upside of horizontal stripe 22 are at a distance of certain distance, this distance equals the gross thickness of lid 18 and blister pack spare 8 cover films 5 at least, edge 14 can be bearing on the back side 21 of adaptor 13, and the while also makes blister pack spare 8 avoid lateral inclination and damages and slip into formula plug-in mounting joint.

In addition, the top edge of last colulus 19 and described horizontal stripe 22 upsides are in sustained height.Constitute the colulus 16 of above-mentioned accessory 16 ' and 16 " stretch out from the middle part of horizontal stripe 22.

As also requiring a kind of fixation except that clamping action in order to avoid

member

8 and 13 is deviate from unintentionally to slipping into formula plug-in mounting joint, this just relates to latch shown in a kind of Figure 19-21.Specifically, this relates to a kind of latch convex body 28 that is positioned on the bottom land 23.Latch recess 29 is used for latch convex body 28.Described recess is positioned at the U-shaped web of colulus 20 down.Latch recess 29 forms a through hole.After constituting, this will state the basis of another function of latch.The above convergent contour of emphasizing is very favourable for the inlet that assembling the time enters interpolation slit 25.The excipuliform projection of latch convex body (do certain exaggerative diagram) is being done corresponding fashionable pressurized is shunk back and is forced to be locked in the recess with latch recess 29.Pass through add suitable pulling force and can unclamp this joint again.

Slip into the width of the plug-in mounting length of formula plug-in mounting joint greater than interpolation slit 25.Its ratio is about 2: 1.The plug-in mounting length of

colulus

19,20 equal 1/5th of blister pack spare 8 length overalls.

Suction pipe 3 carries out clamping by flexing arm 30 and adaptor 13.Flexing arm holds suction pipe 3 " as the Canis familiaris L. of leading with belt ".Like this, can hold suction pipe and make in its effect " radius " and freely shift in necessity.Arm 30 is radially drawn from long tube type suction pipe 3.Notched annulus 31 is as the instrument that clamps arm 30 in the suction pipe side.Arm 30 can be installed on the waist 33 of suction pipe 3 owing to its radial indentation 32.The periphery of waist is circular, and is just similar to the inside of annulus 31.Therefore, at the following annulus that is shown rotary adapter ring 31 with form the performance that has rotation between the waist 33 of annular groove.

Opening 32 with respect to rotary adapter ring 31 on diametric(al) is connecting cord-like arm 30.On the other end of arm 30, form one and add butt end 34.Just formed a spheroid at this place.The action (referring to Figure 12 and 13) that arm 30 is entad done.

Adding butt end 34 makes arm 30 be clamped on the blister pack spare 8 or on the plate 1.Promote blister pack spare 8 plate 1 time and just can draw suitable link position when (referring to Fig. 8,9) as shown in the figure.For this reason, this plate constitutes a dividing plate 35, and this dividing plate has been considered the corresponding section configuration (referring to Figure 22) of blister pack spare 8.The pod part of guiding blister pack spare is with its parallel vertical lateral margin 8 ' in a narrow sense play a part to have dividing plate 35 leaders, these lateral margins are guiding blister pack spare and the downside of plate 1 continues into a spatial accommodation 36, the cavity 6 (referring to Figure 22 and 23) that the size of this spatial accommodation can be held this space to be formed by recess 7.

The downside of spatial accommodation 36 is a rear wall 37.Rear wall does to be parallel to the extension of plate 1.The longitudinal wall that plate 1 and rear wall 37 are fused is shown 38.Longitudinal wall at 8 one edges of the blister pack spare of making lengthy motion picture shape plug-in mounting 14 and another 15 districts, edge and cross wall 39 fuse.This just forms the housing 40 that configuration is very shallow, be similar to cigarette case.

Plate 1 comprises the adaptor 13 of housing 40, covers with folded plate type lid 41.Plate 1 is as the middle cover of device V housing 40 in this respect.

Folded plate type lid 41 is hinged in the bonding pad of adaptor 13.Corresponding hinge axes is shown 42.This axis is positioned at the end regions of this place's rear wall 37, does to be parallel to the extension of the suction pipe 3 longitudinal central axis line X-X that are clipped in the accessory 16 in the space.Under opening, the section of lid is positioned at the outside of housing section.Because hinge axes 42 arranges slightly backward from the hinge side cross wall of folded plate type lid 41, this just reserve cover side hang body 41 '.This outstanding body and function makes to open spacing block body.Opposed block body is made of the back of this place's rear wall 37.

Suction pipe 3 is clamped when blister pack spare 8 is inserted.For this reason, arm 30 resembles an arrow and is placed in the crossbow groove.Like this, with regard to configuration, form a groove 43 at the upside of top colulus 19, this groove also crosses horizontal stripe 22.The cross dimensions of described groove makes arm 30 unlikely rectangle primary section that outwards exceeds colulus 19 when in fact it stretch out as straight line.In addition, groove 43 opens wide to two ends.Arm 30 length should make under the state of being installed and add the opposite side that butt end 34 drops on drop-center 17 inner end peripheries 27.

Described end periphery becomes a cross wall to extend to the upside of blister pack spare 8.But, upwards have the slit 44 of an opening to disconnect by one than baffle element.This slit can make arm 30 therefrom pass through, and the butt end that adds of arm has a spacing block body 45 on end periphery 27 opposite sides that constitute above-mentioned cross wall, and this block body stops the butt end 34 that adds of flexing arm 30 to break away from its state that tacks (referring to Fig. 6 and 7).Drop-center 17 is shown 17 in that part of the end periphery 27 opposite sides continuity that is only disconnected by slit 44 ' and still be a groove.Groove 17 ' the degree of depth less than drop-center 17 degree of depth that are communicated with adaptor.Groove 17 ' section configuration be semicircle.Its size should make at least become spheroid add partly dropping on wherein of butt end 34.Groove 17 ' formation represents, is used to add the vertical passage of butt end 34 with double-head arrow Y.One end at groove 17 ' close blister pack spare 8 another edges 15 has a spacing block body 46 equally.

The described passage of representing with arrow Y enters housing 40 districts at upside and is stacked in extendible portion on blister pack spare 8 or its dividing plate 35 or overlapping portion is that edgewise convex shoulder 47 by plate 1 downside constitutes.The edgewise convex shoulder 47 that section respectively is 1/4th circular arc, respectively replenish part for the hemispherical passage be as shown in figure 23 be provided with in pairs and constitute a slit 48, though this slit can make arm 30 therefrom pass through, can keep upset end 34 here.When arm 30 was in the state of walking down, " bolt band " was unless make spacing block body 45 throw off can not deviate from from housing 40 again.

The slit 48 that extends in housing 40 vertical central planes provides a movable bite in housing one side for arm 30, and this bite satisfies the requirement that comes back operations fully.For being inserted guide hole 2 required operating radiuses, suction pipe 3 satisfied requirement like this, in the vertical.Equally, span also should meet the demands in the horizontal, and for this reason, the length of arm 30 is at least about equaling plate 1 width partly.

The outlet upside of slit 48 has chamfering.This also be applicable to slit keep to the side 15 end 48 ', slit is in the opposite direction, just have opening towards adaptor 13.Constitute, be shown 49 by chamfering on the slit 48 to the inclined side of external diffusion.This shape helps end 34 joints, is just led and the mobility of the spheroid joint of the clamping that is subjected to float.In addition, owing to make slit 48 be slightly wider than the section of arm 30, also strengthened mobility.

Even suction pipe 3 is in the state that is clamped in the adaptor 13, this arm also can be subjected to the protection of mechanically stressed aspect fully.Drop-center 17 and with form of grooves do straight line continuity and be shown 17 ' part be that to be molded in the wall that constitutes cavity 6 intravital quite deeply.Bottom land 23 is positioned at the planar centre-height of blister pack spare thickness place approximately.The suction pipe 3 central longitudinal axis that are clipped in the accessory 16 also extend in this plane substantially.Like this, radially the arm 30 of An Zhuaning just can not have in the groove 43 that is inserted into suitable extension lateral stressedly.

Because folded plate type lid 41 has well-to-do space 50 in hinge one side, therefore can not produce the power of doing of covering 41 aspects from folded plate type.This well-to-do space 50 can be admitted under no stress in the adaptor 13 substantially by what accessory 16 and suction pipe 3 constituted part independently is set.The collapsible opening of folded plate type lid 41 provides carries out the condition that makes things convenient for of freely taking to adaptor 13, thereby can load onto blister pack spare or take off to exist side by side with the blister pack spare of sky and promptly load onto new blister pack spare 8.Under the swing type opening, inlet section 35 ' and the zone of dividing plate 35 upper and lower sides be to open wide fully.

Although the carry limit formula supporting of blister pack spare 8 in slit 35 adds that spatial accommodation 36 has met the demands, but the modification by blister pack spare 8 shown in Figure 32 newly designs a kind of method that adopted, in the method, be provided with the vertical web 51 that is molded into from blister pack spare 8 wall material.In addition, the wall material is made angular bend along periphery in the case.The peripheral narrow wall that curves like this is shown 52.The shape that this has described blister pack spare 8 to can be described as housing rather than the shape of plate body.Vertically the narrow limit and the limit wall 52 of web 51 are in the same plane with its end.

Vertically web 51 from drop-center 17 or groove 17 ' the outside stretch out.This foaming structure of making as mould notes part has been considered above-mentioned cavity 6 equally.Used reference number is identical.

The shell mould foaming structure has rear wall 53 in the side away from plate 1.This just forms an end face with extraneous packing.Cavity 6 that medicated powder 9 is housed here is still to be sealed with cover film 5 as mentioned above.The blister pack spare of finishing 8 is shown in Figure 34,35 and 36.

In the zone on making stand-by blister pack spare 8 between cavity 6 or the cup-shaped recess 7 moisture absorption plug-in unit 54 is housed.Plug-in unit is the shape of small pieces and is contained in the gap 55 that four equidistant cavitys 6 are reserved (referring to Figure 33) by certain position.

Blister pack spare rear wall 53 is enclosed in the groove 17/17 ' both sides cavity 56 that extends in vertical central plane.Hygroscopic effect just independently distributes in the cavity at these two.The height of plug-in unit 54 is identical with cavity 56.The rear wall 53 that is made of aluminium foil just provides a kind of good supporting like this, for instance.

Rear wall 53 and vertical web 51 are bearing in the inboard or the upside of housing 40 rear walls 37.Much less, the downside of cup-shaped recess 7 also may extend into described upside or extends to the upside of blister pack spare rear wall 53.

Shown in figure 32, adaptor 13 is not to be connected with blister pack spare 8 with carvel joint, that is to say, adaptor does not overlap with the profile of blister pack spare 8.Different therewith, adaptor 13 is connected with an edge 14 by a push button joint in the case, specifically, is to utilize the limit wall 52 of edge being bent angularly to connect in the case.This can be referring to Figure 37.

One button half one 57 that constitutes protuberance is that horizontal making come from the sidewall material of described blister pack spare 8.Corresponding therewith recess is positioned at the horizontal stripe 22 of adaptor 13.The push button joint is to design from the notion that pressurization engages, thereby can consciously adaptor 13 be unloaded from the blister pack spare that connects with it.As button half one 57 of protuberance have the mushroom capitiform, laterally have groove, have the convex body of thin handle.The mushroom of a Xing Chenging thickened portion just may be stuck in behind another button half 59 necks that constitute recess on the shoulder 58 thus.In addition, adopted identical reference number for the ease of understanding; Here also leave the leeway of selection, just, the edge of a knife 4 is aimed at the right or the left side of adaptor 13 accessories 16.

The edge of a knife 4 has stent-type or frame-type blade.For the guiding and the location of the circular extension that is subjected to cavity 6, make described blade extend (referring to Figure 24) along diameter line D-D.Otch almost reach the inner edge 6 of cavity 6 '.At first, point of a knife 4 ' the thrust cover film 5 that is positioned at central authorities seal the part 5 of cavity ' central authorities." penetrate and cut, the edge of a knife outside is made the roof type ramped shaped and is fallen and do central authorities' cutting to make the outside 4 of the edge of a knife 4 then.The angle α in the edge of a knife outside 4 ", 4 " is about 120 °.Symmetrical expression extension (referring to Figure 24) is done with respect to the central longitudinal axis X-X of suction pipe 3 in the roof type slope.

The frame-type hollow space of blade is shown 60.This part lead to cutter head and with inhale powder passage 11 and do circulation with ventilation cross-drilled hole 12 and be connected.This part constitutes the dividing plate of inhaling band opening in the powder passage.

Extending plate 61 along the edge of a knife 4 both sides of diameter layout, adjacent flank ground separated by a distance with the edge of a knife, that form the edge of a knife.Plate face 61 after its impact type that suspends ' with the edge of a knife 4 on the periphery that exposes compare significantly and axially shrink back backward.Described plate 61 is separated by a distance with the side of the edge of a knife 4 and do parallel extension by the side.

Plate 61 is as the passing instrument.Plate to the cover film 5 that punctures suspend tensioning portion 5 ' the channeling conduct of joint-cutting edge, make its inner edge that stretches to cavity 6 conscientiously 6 '.This just leaves a hole that section is very big.Therefore, concerning powder 9, can very advantageously flow out cavity 6.

Therefore, as shown in figure 24, can obtain the breach of repeatability all the time.Plate 61 breaks the breach of cutting in advance and it is further pushed back the edge of a knife 4 both sides.Thereby draw outward extending paired wedge-like portion, its submarginal wedge shaped tip is shown 62.This just draw by plate 61 force the tongue shape tabs 63 that is attached on the cavity edge and by seaming and cutting cause, in wedge-like portion 65 and a triangle between the above-mentioned wedge-like portion 62 or a dihedral central flaps 64 that is on the diameter line D-D.

Plate 61 also can have sharp edge as shown in the figure, and this can be very favourable for its traction.

Spacing between the plate 61 is identical with the width that blade framework hollow space 60 is measured on bigger edge of a knife width.Headroom section obviously narrower on the suction pipe 3 joins with the big headroom internal diameter that constitutes suction powder passage U at the root of two members 60,61.Ventilation cross-drilled hole 12 also is located in and forms in the bigger part of this section.

Be provided with the spacing convex body 66 of insertion of suction pipe 3 front ends that are used for to insert guide hole 2 in lower area symmetrically at ventilation cross-drilled hole 12.Be positioned at downside, do etc. angular distribution four substantially and insert spacing convex bodys 66 and make the marginal zone in hole be positioned at the upside of plate 1 guide hole 2.On this position, just can obtain the best insertion depth of the edge of a knife 4 with respect to cavity.

For making the easier grasp of end user, suction pipe 3 has the measure that is locked on the plate 1.For this reason, the front end at suction pipe 3 forms locking dactylozoite 67.Described locking dactylozoite is parallel to that the edge of a knife 4 suspends that shape extends and its end is toward the outer side locking shape 68.Lock out action is conspicuous.

When plug-in mounting suction pipe 3, locking dactylozoite 47 also enters the guide hole 2 that constitutes on the plate 1 of covering plate.

Locking dactylozoite 67 is positioned at the outside of guide hole 2 circular sections, thereby the cross section of the distribution channel that do not account for.Connect room 69 as what the corresponding admittance cavity of locking dactylozoite 67 was provided with equal number, this locking dactylozoite enters the back of guide hole 2 peritremes.Vertically arrange as shown in Figure 1 along housing 40 with respect to guide hole in a row in the described room that connects.Connecting the room is arranged on the common diameter line of guide hole 2.This line can be used as the layout trend of the suction pipe 3 corresponding edges of a knife.Describedly connect room 69 this just is on the direction of insertion, but enter locking room 70 (referring to Figure 22) at plate 1 downside simultaneously.This locking room is by doing a side 68 of lateral arrangement ' block with respect to direction of insertion on the elongated insertion part 68 from following.Described side 68 ' and suction pipe 3 can be withdrawed from from the position that it blocks consciously more not really suddenly.Therefore, locking dactylozoite 67 is inwardly done the resilient radial action in short time in latched connects.Keyed end 68 sides 68 ' radial width equal between suction pipe 3 edge of a knife ends and locking dactylozoite 67 back sides space 71 at least to edge of a knife lateral deviation is moved.

As shown in figure 22, locking room 70 forms by web 72, and web strides across guide hole in a row connects together plate 1.These webs therefore do to be parallel to the extension at guide hole edge and its thickness less than the length or the height of guide hole 2.Locking room 70 has reduced the vertical height of web 72.At upside recess is arranged also in this respect.The upside of web 72 is recessed significantly with respect to plate 1.Like this, if the air inlet of described for a certain reason guide hole 2 is obstructed, just have the distribution network 73 that leads to adjacent passages 2.In a word, should take measures to make the periphery of the edge of a knife 4 and plate 61 to have enough suction air-flows.Flow into path accordingly based on the skew gained of corresponding wall body and in Figure 23, be shown 74.Plate 61 makes the effect that has passing and keep aspect cover film 5 appropriate sections 5 ' break and the turnover, and from then on this also find out among the figure.

With regard to described another effect of locking recess 29, what must illustrate is: recess also with another locking convex body 75 of case side interact (referring to Figure 21).This convex body from housing 40 rear walls, 37 inside protrusions and with its excipuliform structure in this enters the hole.Like this, adaptor 13 and the blister pack spare 8 that suspends on it can only be pulled out in the housing 40 of device V consciously.

Also the edge 15 that blister pack spare 8 parts can be exposed outwards promotes so that take out blister pack spare 8 from housing 4 ends at this place.This is to obtain this suitable operation by the room 76 in the plate 1, this room dividing plate 35 of spatial accommodation 36 adjacency in cross-section and this end regions plate 1 in.In addition, room 76 interacts with the convex body 78 that can suitably insert.This convex body is positioned on the folded plate type lid 41 inboard suitable positions.

78 pairs of hinge axes 42 of this joint convex body have protective effect.In addition, engage convex body 78 and also can make folded plate type lid 41 keep the lock bolt of closing in order to formation, the pairing body of its lock bolt be positioned at the corresponding site in room 76.

Form shown in Figure 1 also can make suction pipe 3 be connected with plate 1 by flexing arm (as a rope), but slave plate 1 a central fixing point is drawn (length of arm 30 is enough to reach all guide holes 2), and it is interior and be not subjected to the restriction of blister pack spare 8 also can to make spheroid 34 still be clipped in slit 49.The colulus 16 so slit 49 can be sealed at two ends ' and 16 " can be contained on the plate 1.

Spheroid 34 and so on is become movably and be clamped in the groove, preferably be clamped in the drop-center 17 of blister pack spare 8, in the case adaptor 13 also can be shifted thereupon or replace another kind of clamping device so as with suction pipe 3 in that the time spent is not fixed on the blister pack spare.

All features that disclose are being the most basic to the present invention.In addition, listed the relevant disclosure of property data (Xerox of former first to file) in advance in as extention in the present disclosure of the invention, this is for the feature in these data is also included within claims of the application.
