Abstract

Described is a dispenser (1) for inhalation purposes, with a dispenser unit (3), a fluid pump and an air pump. The two pumps are operated by an energy accumulator (12) which is tensioned by a tensioning device (10) and triggered by a triggering device (11) in such a way that all the pumping work is performed by the energy accumulator (12). The invention makes it possible to dispense individual doses of relatively large volume very simply without using a propellant.

Description

The invention relates to a discharge device, in particular should be particularly suitable for a discharge person using the direction by physical or conscious Actuate the discharge of at least one flowable me causes diums. At least one medium can be gaseous, be liquid and / or powder or powder and at for example as an active pharmaceutical ingredient, such as Inhala tion active ingredient. Are means according to the invention biased discharge of at least one medium is provided, this can be done in a short time and if necessary with little actuation can be applied by a relatively large discharge amount.

In numerous applications, it is desirable for Discharge a lower actuation than the discharge force to need power, e.g. B. in weakened people or because of difficulties in coordinating activity and application. Discharge device operated with propellants can be operated with little force,  however, blowing agents are not only of concern their immediate medical effects, but mostly also very harmful to the environment. With such discharge Use the measuring valves to meter the discharge det, practically only a transfer of the propellant takes place telmixed medium from a main memory into a Dosing chamber from which the discharge then takes place without the discharge force is biased during this process would have been. This discharge force is usually much greater than the operating force, so that a bias and after following triggering of the actuation or valve opening by virtue of not using a propellant.

The invention is further based on the object of a To create discharge device of the type mentioned, which Avoids disadvantages of known training and in particular the blowing agent-free discharge of at least one medium an actuating force that is lower and / or to apply for a shorter period than the required off load capacity.

Means are provided to solve the problem for an off carry cycle required at least partly to convey an energy storage and through Triggering from this then towards at least one medium transmitted that it is carried out under this energy. The energy storage is at least partially unload. Means are advantageously provided to the Ener giespeicher then again at any time by physical activity, for example, to be able to charge manually. This can on the use of such blowing agents in particular be wisely or entirely, which by expansion at Transition from the liquid to the gaseous state.  

The energy storage device can store the energy in the form of a repeatable pressurized, flowable medium save, but it is useful as a mechanical energy giespeicher formed, which acts on a pressure chamber, from which the media batch to be discharged z. B. by Chamber narrowing is displaced.

The discharge energy is expediently reduced to at least one Transfer media pump, the pump chamber of the pressure chamber forms. Pumps of any design are conceivable, however, preference is given to thrust piston pumps, the discharge force on at least one of two via a pump stroke mutually movable pump parts linear expediently so that is transmitted exclusively through this discharge energy a full pumping stroke is carried out. This pumping stroke can be stop-limited and the pump chamber a do Form sierkammer so that the amount of media applied is precisely defined.

With the described or another discharge device device, in particular as an inhalation device or as a device is provided with which an active ingredient mixed with air to be applied, it is advantageous if for this Air a special air pump is provided, the preferred as assigned a clamping device of the type mentioned is. In the case of an inhalation device, the air must then be closed at least not completely by suction of the Breathing air is evoked, but this air is over an air reservoir, an air pump and / or the like. Simultaneously fed under pressure.

Appropriately, at least two pressure chambers in the Media carried out essentially simultaneously, whereby at least one pressure chamber through a pressure accumulator  and / or at least one to all pressure chambers by pump pen chambers are formed. The discharge promotion of a gas shaped medium or the air can in front of the discharge start with a liquid or powdery medium and / or end after its funding, so that from the beginning an even admixture of air and even discharge tion or cleaning of the associated duct sections is guaranteed.

The tensioning device expediently forms a ge closed unit that a discharge or actuation head at the end of a valve and / or piston tappet, its discharge opening expediently from that to the discharge unit axially parallel or coaxial position deviates and approximately radially can lie. This discharge unit can in itself again units that are easily detachable from each other, which a media storage, a pump unit with Befe Form stigungskappe and / or the actuating head, which can have a recessed nozzle cap. The associated discharge nozzle is not through the main body of the Discharge device formed or not the clamping device tion belonging so that in one and the same basic body optional discharge units with discharge openings are used can be differentiated depending on the needs discharge characteristics.

The discharge unit is intended for this after emptying against a still filled on the same body to be changed, there is a new one with each change Discharge nozzle available. The discharge unit can, however also intended to be so firmly enclosed in or in arranged to the clamping device or the base body be that after emptying it is disposed of.  

For safe storage of the discharge unit, this is appropriate except for the support against the actuation pressure non-contact compared to the housing-shaped base body e.g. B. centered in a cup-shaped driver net that in the initial position of the media storage essentially lies completely within the bowl. In tension position, the bowl can also be the pump unit and / or the Take up the actuator head at least partially, for what end of the bowl associated with the bowl opening in the interior white te can be enlarged accordingly.

A release handle to release the saved trip Carrying energy conveniently grips a ring shoulder of the discharge unit and / or the driver. The Ring shoulder can be formed by a cap with which the pump unit on the neck of the media storage is attached and / or can be through an end face of the Driver be formed. Furthermore, the trigger handle designed in the manner of a one-piece, two-armed lever be, one arm of which the exposed handle and whose other arm is an inside of the housing Locking member forms that immediately to be locked Counter surface rests against spring force.

For manual tensioning of the tensioning device is advantageous a two-armed lever is provided, the one arm end pivotable on the base body about a fixed axis is articulated while the lever is articulated between his arms is connected to the driver and this joint that has the required radial play. At least one lever can be in the starting position completely within the reason body housing and only in the area of the outside side of the discharge device with the outlet mouth a handle, which is essentially one  tightly closing on the face of the exit mouth fitting lid and / or a tight fitting endab covers an associated end wall of the base body. As a result, the mechanics of the clamping device remain in the tensioned condition essentially shielded from the outside. The tension lever is via at least one snap connection connected to the driver, so that these two parts at the assembly of opposite ends or sides of the Basic body used here and when inserting each other can be connected. This snap is useful bond formed by said joint.

The tensioner or tensioning lever can also by at least a circumference limitation of the exit mouth can be formed or form this exit mouth. Is one between one sunken rest position and a protruding use position movable discharge nozzle provided, so results a very compact design when not in use dung, and also this spout can be used as a tensioner be arranged so that when it is transferred to Ge position prestresses the energy storage at the same time.

The discharge device 1 is essentially composed of a housing unit 2 and a discharge unit 3 which, after detaching, is suitable for the discharge of at least one medium through an atomizing nozzle without additional components. The housing unit 2 essentially forms with a housing 5 a base body 4 , which is approximately square in cross section with strongly rounded corner areas and is composed of two axially adjoining, approximately cup-shaped housing parts 6 , 7 via a snap connection. A housing part has an oblique to the housing axis or approximately radially abste existing discharge nozzle 8 , which in view substantially has an elongated rectangular cross section te over its length and is therefore advantageously suitable as a mouthpiece for sealing with the lips. Its end forms a corre sponding, exposed exit mouth 9 through which the media of the discharge device 1 are discharged.

In the single housing space of the housing 5 , a tensioning device 10, which is completely shielded from the outside, and a release device 11 for triggering the tensioned state is arranged. A coaxial to the discharge unit 3 force accumulator 12 in the form of a helical compression spring rests on the end of the discharge unit 3 remote from the outlet mouth 9 and can already be pre-tensioned in the initial state. In the longer, from the discharge nozzle 8 th, one-piece housing part 6 is a cup-shaped Aufnah me 13 axially slidably mounted along ribs which are distributed over the inner circumference of the housing part 6 . The bottom of the receptacle 13 resting in the starting position on the bottom of the housing part 6 forms a driver 14 for the associated end of the energy accumulator 12 , the other end of which is supported on the associated end of the discharge unit 3 . The discharge unit 3 is guided axially relative to the receptacle 13 on ribs which are distributed over the inner circumference.

To increase the voltage of the energy accumulator 12 , a tensioner 15 to be operated manually by pivoting is provided. The tensioned position is secured by a lock 16 , which can be transferred to the release position via an actuator 17 . The actuator 17 is at the inner end of the through the discharge port 8 gebil Deten shaft 18 in the form of a shaft in the starting position substantially blocking flap, which can thereby be pivoted into the release position that 9 breathing air is sucked in through the outlet mouth. The entire release device 11 and the lock 16 are combined to form a self-contained assembly 19 which, before the housing 5 is closed, is inserted into the housing part 7 and is secured by bracing between the two housing parts 6 , 7 . The lock can also be done manually and released by releasing it.

The discharge unit 3 has a pump unit 20 which can be actuated manually by thrust pressure and has two pumps 21 , 22 which are located directly axially one behind the other. A Schubkol ben pump 21 is used to discharge a liquid and has a piston unit 23 which delimits a pressure chamber 24 . The other push piston pump 22 serves as an air pump and has a correspondingly further pressure chamber 25 . Your piston is fixed to the cylinder of the pump 21 , against which the cylinder is moved together with the piston unit 23 . The pump 21 sucks in on the return stroke via an inlet valve 26 , which closes depending on the path after a first partial stroke of the pump stroke. At the outlet, the pump 21 has an outlet valve 27 provided on the piston unit 23 , which can open in a pressure-dependent manner before reaching the pump stroke end or is forced to open when this end position is reached by a stop, so that the medium from the pressure chamber 24 into a shaft 29 on the piston provided outlet channel 28 flows. The suction from the atmosphere via a suitable inlet valve pump 22 emits via a pressure-dependent controlled Auslaßven valve 30 , which is immediately adjacent to an outer end portion of the outlet channel 28 and has an opening 31 to this; this outlet valve can also be opened instead or additionally when the associated pump stroke end position is reached by a stop or the like.

The mouth 31 is located directly behind a nozzle cap 32 , which forms an outlet opening 33 or atomizer nozzle approximately perpendicular to the central axis of the discharge unit 3 and is provided in an actuating head 34 forming the associated end of the discharge unit 3 . The actuation supply head 34 , which forms the cylinder of the pump 22 , is attached to the piston skirt 29 , which passes through the pressure chamber 25 . For both pumps 21 , 22 , a common return spring 35 is provided within the pump 21 , which may optionally also be designed as a return spring working against the energy accumulator 12 , so that no external spring is required for the return of the discharge unit 3 to the starting position is. The pump unit 20 is attached to the cylinder housing of the pump 21 by a cap 37 on the neck of a media store 36 , which engages in the receptacle 13 , forms the system for the energy store 12 , protrudes in the starting position over the open end of the receptacle 13 and is completely inside the Housing part 6 is adjacent to the unit 19 .

The discharge pre is particularly suitable as the discharge unit Direction according to DE-OS 37 22 469, because of others Features and effects are referred to. Such Discharge device is with an operating force in the Order of 10 kilopond to operate, which by the Training according to the invention is significantly facilitated.

The receptacle 13 , which lies completely inside the housing, has two tab-shaped projections 38 , which are located opposite one another on both sides of the media store 36 and protrude beyond its open end and are each connected to the tensioner 15 between the assembly 19 and the housing jacket via a joint 39 . The joint has a slot-shaped transverse opening on the shoulder 38 and a joint pin engaging in the tensioner 15 , which can be snapped into the joint opening via a groove with an oblique bottom surface to form a snap connection 40 transverse to the joint axis.

The tensioner 15 is pivotally mounted on the side of the joint 39 facing away from the discharge nozzle 8 with a joint 41 on the housing 5 or housing part 7 . For this purpose, the tensioner 15 has two levers 42 which project laterally into the shaft 18 on both sides, lie on both sides on the outer sides of the structural unit 19 , and in cross-section essentially follow the inner contour of the housing 5 . The levers 42 have at their ends outwardly directed pivot pins which are snapped into openings in the jacket of the housing part 7 . The ends of the levers 42 removed from the joints 40 , 41 pass in the starting position in the region of the mouth 9 into a clamping handle 43 , which in this region forms a plate-shaped cover 44 which bears against the end face of the discharge nozzle 8 and thereby the outlet mouth 9 essentially closes tightly. The lid 44 is angled at the associated end of the housing part 7 side of the discharge nozzle 8 into a cover part 45 which closes slots 46 in the associated cover wall in the starting position.

For tensioning, the handle 43 is pivoted about the hinge 41 lying at an axial distance from the inside of the associated end wall by about 90 ° to an end position. Here, the lever 42 exiting through the slots 46 take the receptacle 13 via the joint 39 , so that the driver 14 moves under compression of the energy accumulator 12 against the discharge unit 3 . In this clamping position, the tensioner 15 and therefore the energy accumulator 12 are in a manner not shown, for. B. secured by detent.

The trigger device 11 and the lock 16 are provided on a substantially jacket-shaped bearing body 47 of the unit 19 , on the outside of which the levers 42 and lugs 38 are located and in the interior of which an annular or fork-shaped locking lever 48 is provided, between the two fork arms the discharge unit 3 engages. The locking lever 48, which is angled essentially twice, is pivotably mounted on the bearing body 47 in the manner of a two-armed lever with a joint 49 which is parallel to the joints 39 , 41 and is formed by snap members. At its lever end, which is closer to the discharge side, a release lever 50 is mounted with a joint 55 which projects freely from it along the inside of the housing 5 in the direction of a joint 51 of the actuating member 17 and likewise forms two fork arms lying on both sides of the actuating member 17 .

In the locked position, the release lever 50 lies with the end surfaces of its fork arms on the circumference of an articulated hub of the actuating member 17 , which is mounted on the bearing body 47 between two bearing cheeks and lies between the levers 42 . This hub has projecting cams 52, which 50 push away the release lever in the forward swing of the operating Glienicke of 17 of the hub so that the release lever 50 is released and can be approximately slide up to the inside of the outlet side end wall of the housing 5 along the hub. In the locked position, the locking lever 48 rests with a cam on an annular shoulder of the media store 36 , which is formed by the transition from the neck of the vessel.

When the locking lever 48 is released by the release lever 50 , the locking cam slides under the force of the energy accumulator 12 and against the low force of a return spring 53 along this shoulder surface until it has reached its release position according to FIG. 3. The media storage 36 performs with the cylinder unit of the pump 21, the pump stroke movement relative to the actuating head 34 . This movement begins slowly due to the lever ratios and then accelerates, so that there is a favorable, damped discharge characteristic. Against the actuating pressure, the actuating head 34 bears with its free end face against a fixed stop 56 , which can be formed by the bearing body 47 and / or the end wall of the housing 5 .

The return spring 53 is articulated in the form of a tension spring on the crosspiece of the locking lever 48 , which can strike in the release position on the outer circumference of the media store 36 . In this respect, a position is shown in Fig. 3, which can only be reached when the media storage is removed. In free order, this lever end of the locking lever 48 dips into the receptacle 13 . The bearing body 47 is tightly clamped with an end collar 54 resting against the end face of the housing part 6 between the housing parts 6 , 7 .

During the discharge process, additional air can be sucked in directly from the atmosphere via the slots 46 or other slots with the mouth enclosing the discharge nozzle 8 . After completion of a discharge process, the handle 43 is pivoted back into its closed and initial position, whereby the driver 14 is inevitably returned to its initial position. At the same time, the return spring 35 returns the discharge unit 3 to its initial position, possibly against the force of the force accumulator 12 . The return spring 53 pulls the locking lever 48 into its locking position, and the release lever 50 pivots back under weight and / or spring force into its locked position, in which it strikes the inner surface of the bearing body 47 . The actuator 17 comes under Ge weight and / or spring force back to its starting position. The discharge device 1 is thus ready for a wide clamping and discharge process.

So that only a small or precisely defined flow force is required for the transfer of the actuator 17 , the free end in the end wall 58 of the housing 5 Ge is assigned at least one suction opening 57 , which is expedient approximately from the area immediately adjacent to the inside the top wall 58 lying end of the actuating member 17 extends in the direction of the outlet mouth 9 . A plurality of elongated or slot-shaped suction openings 57 are expediently provided next to one another. For the end of the actuator 17 , a concave depression corresponding to its swivel path is provided on the inside of the top wall 58 . The actuating member 17 is approximated by beveling at the end of an airfoil profile such that air flowing through the suction openings 57 along its front plate side in the direction of the joint 51 and deflected towards the outlet mouth 9 generates a relatively large negative pressure as the actuating force on the front plate side. The suction openings 57 are covered by the handle 43 in the starting position.

Referring to FIGS. 6 to 8, a manual triggering of the discharge process is provided. For this purpose, the actuating member 17 is pivotally mounted as a pivotable push button on the side facing away from the discharge 8 simply by snapping into an opening in the casing of the housing 5 as a two-armed lever. The inside, in one piece with the actuator 17 lever arm is the Sperrhe bel 48 , which rests with a cam portion locking against a shoulder of the cap 37 of the discharge unit 3 and with a Druckfe lying between it and the housing which is loaded as a return spring 53 . After tensioning, only the actuator 17 needs to be pressed against the outer side of the housing shell in order to trigger the force storage so that the pumping work is transmitted.

The housing 5 or the housing jacket is essentially formed in one piece over its length and is permanently open at the bottom end for inserting the receptacle 13 . When inserting the discharge unit 3 , the receptacle 13 and the force accumulator 12 unit from this housing end, the lugs 38 reach the area of the pivot pins of the tensioner 15 previously used in the opposite position from the end wall 58 in the initial position. From the end of each slot-shaped joint opening 59 , in which the pivot pin 60 is in the starting position, a funnel-shaped groove 61 with a sloping bottom surface 61 leads to the end face of the associated extension 38 . When inserting the above-mentioned assembly, the joint pins 60 enter the grooves 61 and slide with their accordingly beveled end faces on the bottom surfaces until they snap into the joint openings 59 like barbs. This makes assembly very easy. The Aufnah me 13 is provided with projections or ribs, the hen both over its inner circumference and over its outer circumference, and secured against rotation with the outer ribs relative to the housing 5 or its longitudinal ribs.

An energy storage can be seen in the form of a single spring, the z. B. has approximately the same outside width as the part to be moved and can therefore be centered together with this as a spring mounted only by inserting. Referring to FIGS. 10 to 13, the energy accumulator 12 may also comprise two or more springs, such as tension springs, act not directly on the discharge unit, but on the driver 13, the side immediately adjacent to face the periphery of the discharge unit 3 and the driver 13, against this have a greater length and / or extend over most of the length of the housing. The two energy accumulators 12 are located on both sides of the discharge nozzle 8 and are only mounted by hanging their free, curved ends. The driver 13 has for this purpose on its outer circumference protruding lugs 62 which are adjacent to its bottom wall. If this bottom wall is formed by an externally accessible and easily detachable cover 63 , the discharge unit 3 can easily be replaced. The receptacle 13 engages with at least one rib-like guide projection between the energy stores.

The tensioner 15 is formed by the discharge nozzle 8 , which can be folded over less than 90 ° on its side facing the housing base with the joint 41 . In the initial position, the outlet mouth 9 lies completely within the housing 5 on the inside of the top wall 58 . A then still outside, the outlet mouth 9 delimiting jacket part of the discharge nozzle 8 forms the associated part of the housing jacket in the manner of a continuous continuation. On the inside of this jacket part the levers 42 are provided on both sides laterally above, which are mounted directly bar adjacent to the inside of the housing jacket in the joint 41 and in the inner ends of which the associated ends of the energy accumulator 12 are suspended.

The clamping handle 43 is formed by the free end of the jacket part of the discharge nozzle 8 and formed in one piece with the levers 42 . When opening the discharge nozzle 8 in the discharge position, the Kraftspei cher 12 are immediately tensioned. In the discharge position, the discharge nozzle 8 is secured with the energy stores 12 by locking 64 ge. For example, the discharge nozzle 8 adjacent to the joint 41 on the outside of its jacket part has a locking cam 65 which jumps behind the associated edge of the opening of a housing jacket which receives the connector 8 . In the discharge position, the discharge nozzle 8 essentially completely closes this opening with at least one corresponding extension 66 , so that the interior of the housing 5 is only connected to the outside via the shaft 18 . The extension 66 can be supported in the rest position on the end face of the actuating head 34 .

The manual actuator 17 is in this case on the discharge nozzle 8 associated front of the Ge housing 5 and expediently triggers with its locking lever 48 in an associated end face of the receptacle 13 . Fixed stops 56 for the actuating head 34 can be formed by a transverse wall and / or lateral inner projections of the Ge housing 5 , which rest against an annular shoulder of the actuating head 34 at a distance from the end face and zen this on the circumference in the manner of a three-point support. In this case, the housing 5 has cross sections with a U-shaped jacket region and a front wall connecting the U legs, which is curved with a radius that is substantially larger than half the housing width. This allows the discharge device to be gripped very well during use.

The individual features of each embodiment can also by replacing each of the other embodiments or be provided by additional addition. E.g. can have different force in one embodiment memory, different actuators, difference Liche tensioner or the like. Provided. Everyone can too Component may be provided individually instead of multiple times.
