Use for the application of medicines.
The The invention relates to an inhalation device for a particular powdered medium with a housing with at least one media store and an outlet channel, wherein a first end of the outlet channel opens in the region of the media reservoir and a second end to flush Attach to a breathing opening a user is formed so that the stored in the media storage Medium is inhalable by inhalation by the user.
Such an inhalation device is for example from the EP 0957962 B1 known. The disclosed therein device consists of a plastic housing with two media storage, the powdered content is discharged through insertion of an extension piece into a nostril of the user and subsequent inhalation through the extension piece. The device is particularly suitable for nasal media that contain a drug combination of active ingredients.
When disadvantageous of this and similar Prior art devices are considered, in particular especially young and older users Have problems with it perform the required inhalation process as vigorously and long as it for inhalation of the entire medium is required.
The The object of the invention is a generic inhalation device whose discharge process is then successfully and completely carried out can if inexperienced or physically limited Users, especially younger ones or older Users using inhalation device.
According to the invention this Task by an inhalation device of the type mentioned solved, which is a respiratory assistance device that is detachable with the housing is connectable and from the housing a the inhalation supportive Air flow by means of a manual operation can be fed.
It is in the device according to the invention is a two-part System whose components can be assembled and disassembled by the user are. One component, the housing of the inhaler, is preferably also used separately, so that the respiratory assistance device only needs to be used by the users who a designated Otherwise inhalation process would not be possible. The housing of the inhalation device may be made in one or more parts and is preferably made of plastic, for example by injection molding. It contains the Media storage in which the medium stored up to a discharge process is. This media storage is preferably until use of the Inhalationsvorrichtung by means of a film verschlos sen, the first in the course of an activation for the discharge process at least partially removed or broken and prevents previously accidental escape of the medium. The at the housing provided outlet channel is designed so that it communicates with the breathing opening of the User flush can conclude. In an inhalation device according to the invention for one nasal application, it preferably has a round or oval Cross section, whose diameter is approximately the size of a Nostril of the target group is adjusted.
With this case the inhalation device is the respiratory assistance device connectable such that by a dedicated outlet opening of the Respiratory support device exiting Air in the case pour in can. The housing is designed so that this air flow to the media storage supplied is blown and thereby the medium in the exhaust duct and then be discharged. The generation of the air flow can be immediate through manual operation done, for example, using a manually operated Piston pump. Appropriately but also the use of a powered from an energy storage Be pumping means, for example, an electrically operated, at an indirect manual operation only in the form of an operation a switch takes place. The manual operation is preferably at the respiratory support device itself or in conjunction with the respiratory support device, for example by squeezing the composite of respiratory support device and housing. However, embodiments are also conceivable. where the actuation the respiratory support device on the housing he follows.
When using an inhalation device according to the invention, the user's inhalation process and operation of the respiratory assistance device are timed by the user such that the powdered medium is simultaneously drawn into the outlet passage by the user's inhalation and injected into the outlet passage through the breathing assistance device. The inhalation process is therefore particularly safe, and it is guaranteed that even in problematic conditions, such as inexperienced or physically restricted users or even very large amounts of the medium the entire amount of media is completely inhaled.
Next the advantage in terms of a successful inhalation also by problematic target groups, has an inhalation device according to the invention even more benefits. The respiratory assistance device may be multiple times which is environmentally advantageous is. Furthermore, with appropriate design, the housing without special adjustments with and without respiratory support device be used so that opposite alternative embodiments, where the respiratory support device integral part of the inhalation device is, larger and larger thus more economical quantities of the housing can be produced.
In a development of the invention is the respiratory assistance device for one manual operation in an actuating direction formed to a main extension direction of the outlet channel is parallel.
By This form of design avoids the danger of being in the train the manual operation the respiratory support device slipping out or slipping of the outlet channel from the breathing opening of the User is caused. An actuation leads at most to a movement in the main extension direction of the outlet channel, in a nasal Application so that the outlet channel into the nostril of User is pushed further in.
In a development of the invention knows the respiratory support device a compression chamber whose volume by manual operation immediately mechanically reducible.
A such respiratory assistance device can be made very easy and is therefore special inexpensive. In the simplest case, the respiratory assistance device has a simple Pump ball on, to the actuation enclosed with the whole hand and then compressed.
Especially it is advantageous if the respiratory assistance device has a bellows.
One Such the compression chamber forming bellows can due to the design-related defined actuation direction with only one or two fingers are operated, so that the entire inhalation device can be handled with just one hand. Such a bellows is preferably made of an elastomer or a thermoplastic, for example made of polyethylene. Preferably, the bellows is integral with an adjoining one Connecting portion for attachment to the housing formed, wherein the elastic Material in the attachment of the respiratory support device on the housing is advantageous. However, they are also embodiments appropriate, at where the connection section is provided as a separate component, which, for example, over a form-fitting Engaging a circumferential web of the bellows in a circumferential groove the connection portion is connected to the bellows. The orientation the bellows is preferably such that a bellows compression towards the case the respiratory support device to be done. However, other embodiments are also conceivable, for example, where the bellows by compressing its two end faces actuated being, the case being is provided on an intermediate side of the bellows. The bellows is preferably by means of a Spritzblasverfahrens or an injection stretch blown process.
In a development of the invention is at one of the respiratory assistance device opposite Side of the housing a finger rest provided.
These Finger rest guaranteed safe handling, in which the operation of the inhalation device, in particular when using a respiratory assistance device with a defined actuation direction, by simply squeezing the one on opposite Pages of the inhaler attacking finger is performed.
In In a further development of the invention, the respiratory assistance device and the case formed in a contact area such that one through the manual operation applied force to a dense pressing together of the housing side and breathability device side Sections in the contact area leads.
Of the Contact area, for example, by a circumferential annular surface on the housing of the Inhalation device as well as a corresponding circumferential area at the respiratory support device be formed. When a force is applied for the purpose of the operation, by the housing and the respiratory assistance device pressed against each other be so leads This is a particularly safe investment of the surfaces together. An exit relevant amounts of the effluent from the respiratory support device air into the environment is thereby prevented.
In a development of the invention, the respiratory support device and the case in a contact area force and / or form-fitting acting sealing and / or securing means.
These Sealing and / or securing means ensure a secure connection of the housing Inhalation device with the respiratory assistance device. Through her is guaranteed that even with an overpressure in the respiratory support device or upon elastic deformation of the respiratory assistance device in the course of the operation a detachment this from the case is avoided. As a sealing and / or Securing means offer in particular positive locking means as latching arrangements, for example, a housing-side locking lip, the in a breathability device side Groove engages.
In a development of the invention, the securing means a the housing side Push-up cone and breathability device side Postponement section.
One Such securing means acts positively. The postponement section is deferred until the postponement cone until by one occurring elastic stretching of the Aufschubabschitts or an elastic Upset of the extension cone sufficient holding force is present. Especially advantageous embodiments are in which in the contact area an air duct for air transport in the housing remains open, for example by cone-side axial grooves or by aufschubabschnittsseitig inside Molded ribs, which in the attached state on the extension cone abut while Spaced areas between the ribs from the Aufschubkonus are.
In a development of the invention, the housing is in several parts, in particular formed in two parts, wherein in a first housing part the at least one media store is formed and at one second housing part the outlet channel is formed and wherein a circumferential contact area between the respiratory support device and the second housing part as in operation to the outside airtight contact area is formed.
at such an embodiment is the overall system of housing and respiratory assistance device Easily sealable in the circumferential contact area. The from the respiratory support device flowing out during operation Air can pass through stomata, which are provided between the first and the second housing part, flow past and so on the respiratory support device opposite side of the first housing part arrive, on which the at least one media storage preferably is arranged. Particularly preferred are embodiments in which the two housing parts in the main extension direction of the outlet channel against each other are formed and where a relative displacement to each other in the course of activation takes place, through which the medium after Outside covering protective film opened becomes.
In a development of the invention are detachable on the housing activation blocking means provided in the assembly of the housing with the Breathing assistance apparatus prevent the first housing part and the second housing part move relative to each other.
These Activation inhibitors ensure that not pushing and securing the respiratory support device to the housing to an opening preferably closed by a foil media storage leads. This makes it possible the housing side or breathability device side Provide securing means, the first by applying a considerable Force be transferred to a secure state without it to accidental discharge of the medium comes. Such activation blocking agents may be, for example by removable circumferential safety strips between the housing parts, through Safety bars for breaking out or through bayonet mechanisms be realized.
at a development of the invention, the housing is by injection molding and / or the bellows is injection blown.
These Manufacturing processes are each very low-priced and reliable Manufacturing process there.
Further Advantages and features of the invention will become apparent from the claims and the following description of a preferred embodiment of the invention, which is illustrated with reference to the drawings. there shows:
1 an inhaler housing in a non-activated state without a breathing assistance device,
2a and 2 B a breathing assistance device with a bellows in a front view and a plan view,
3 from the case of the 1 and the respiratory assistance device of the 2a and 2 B composite complete inhalation device,
4 the inhalation device in an activated, ready-to-use state and
5 the inhalation device during the discharge process.
1 shows a housing 10 an inhalation device according to the invention. This case 10 consists of a first housing part 20 in which 1 invisible way two media storage 24 are provided, each with a powdered medium 30 are filled. In a contact area at the lower end is the first housing part 20 as a conical marsh 26 educated. On the first housing part 20 is a second housing part 40 placed on top of the first housing part 20 opposite side an outlet channel 42 as well as a finger rest 44 having. The two housing parts 20 . 40 are in the illustrated state, the delivery state of the housing 10 corresponds, by means of a simultaneously serving as a tamper evident ring 50 connected to each other in that they are in the direction of a major axis 2 of the housing 10 before removing the circlip 50 are not movable relative to each other.
The second component of the inhalation device of the invention described herein is the respiratory support device 60 that in the 2a and 2 B is shown in a front view and a top view. It has a bellows 62 on top of a compression chamber 62 forms. At the upper end, a cylindrical connection section closes 64 to the bellows 62 at. The entire respiratory support device 60 is made in one piece from an air-impermeable and elastic material, preferably made of polyethylene. On the inside of the connection section 64 are a total of four ribs 66 provided as local thickening of the terminal section 64 are formed.
3 shows the case 10 the inhalation device and the respiratory assistance device 60 in an assembled state, wherein the respiratory assistance device 60 in the area of the connection section 64 is shown cut. The housing 10 is still in the same by the security section 50 secured state as in 1 , The elastically formed connection area 64 is on the conical contact area 26 of the first housing part 20 of the housing 10 postponed. During postponement, the securing section ensures 50 that the two housing parts 20 . 40 do not move relative to each other. The cone trunk 26 of the first housing part 20 and the connection section 64 are dimensioned so that the connection section 64 tangentially elastically stretched, so that a frictional connection between the respiratory support device 60 and the housing 10 comes about.
4 shows in a partially sectioned view of the inhalation device after removal of the locking ring 50 and after activation, by telescoping the two housing parts 20 . 40 is brought about. This is in the course of insertion of the second housing part 40 in the first housing part 20 an inner channel section 46 the outlet channel 42 through a protective film 22 through in one of the two media storage 24 pressed and this thus opened. The second housing part 40 so far on the first housing part 20 deferred until an annular contact area 48 of the second housing part 40 on the annular end face of the connection section 64 the respiratory support device 60 rests.
In this activated state, the inhaler is brought by the user to his nose and the outlet channel 42 inserted into a nostril, the outer wall of the outlet channel 42 flush with the nostril, and inhale through this nostril only through the outlet channel 42 through is possible. For inhalation of the medium 30 The user then closes the other nostril with one hand and then actuates the inhalation device with the other hand while inhaling through the nose. Actuation is by squeezing the bellows 62 in an actuating direction 4 , It is done by holding the index finger of the actuating hand on the finger pad 44 resting and the thumb on the bottom 68 the bellows 62 be squeezed resting. Due to the parallel alignment of the main extension direction 6 the outlet channel 42 and the direction of actuation 4 the bellows 62 and their small spacing, a slipping out of the nostril is not to be feared. At most a slight and insignificant displacement of the device in the main direction of extension 6 the outlet channel 42 can be a consequence of the operation. However, this is not a problem for a successful inhalation.
As in 5 is shown, escapes in the bellows 62 previously located air from the bellows 62 along the arrow direction 80 in the case 10 , She streams into the media store 24 and blows the powdery medium contained therein 30 in the entrance page 42a the outlet channel 42 , At the same time the air gets through the outlet side 42b through the inhalation process of the user along the arrow 82 drawn into the nose of the user. The overpressure that the air from the bellows 62 in the case 10 caused, as well as the negative pressure in the outlet channel 42 By inhaling by the user together lead to a complete promotion of the powdered medium 30 through the inner channel section 46 the outlet channel 42 through the nose of the user.
Even if the exhaust duct 42 is not flush with the inside of the nostril of the user and even if the user is too weak or short of breath to be able to breathe strong enough throughout the inhalation process, is due to the pressure in the housing 10 nevertheless achieved a complete promotion of the powdery medium.
After this the powdery one Medium was consumed from the media storage, the bellows can from the case be deducted again and to a new, not yet used up Housing of a inhaler be infected again.
The housing 10 The inhalation device can without constructive changes without bellows 62 so that a high degree of flexibility is achieved: users who have difficulties with inhalation use the inhalation device including the bellows 62 , such users who use it without bellows 62 no problems, can dispense with its use.
