    The present invention relates to a fluid dispensing device synchronized with inhalation, and more particularly to an inhalation device of the aerosol type synchronized with the inhalation.
    Inhaling devices generally referred to as B.A.I. (meaning "Breath Actuated Inhaler"), are well known in the state of the art. The main advantage of this type of device is that the distribution of the product is synchronized with the inhalation of the patient, to ensure a good distribution of the product in the airways. Thus, in the field of aerosol devices, that is to say those in which the product is distributed using a propellant, many types of devices for triggering by inhalation have been proposed. However, these devices have the disadvantage of having a large number of parts, that is to say, they are complicated and expensive to manufacture and assemble, which is obviously disadvantageous. It is also difficult to find the right balance between reliable triggering at each inhalation, without the triggering threshold being too high, and a lock robust enough to prevent accidental or unwanted actuation. However, if the lock unlocks accidentally, the device is operated automatically and the dose is distributed, even if the user did not want it.
    Thus, more than the automatic actuation of the device, what is important to obtain a good distribution of the dose is to achieve this distribution in a manner synchronized with the inhalation of the user, even if the actuation or triggering itself remains manual.
    The object of the present invention is to provide a fluid dispensing device synchronized with the inhalation which does not reproduce the aforementioned drawbacks.
    It is another object of the present invention to provide a fluid delivery device synchronized with inhalation which improves operating reliability, ensuring effective actuation with each inhalation.
    The present invention also aims to provide a fluid dispenser device synchronized with the inhalation which minimizes the risk of accidental or unwanted actuation.
    It is another object of the present invention to provide a fluid delivery device synchronized with the inhalation which does not have an excessively high triggering threshold, thus enabling relatively weak persons, such as sick or elderly persons, to use the device safely and reliably.
    The present invention also aims to provide a device for dispensing fluid synchronized with inhalation that is simple and inexpensive to manufacture and assemble.

    Advantageously, said locking element is assembled on a rod integral with the piston, so that upon inhalation, said rod moves radially deforming and / or displacing said axial extension towards its actuated position.
    Advantageously, said actuating element is a locking element which, in the non-actuating position, allows the axial displacement of said metering valve valve together with said reservoir in the body, preventing the actuation of said metering valve when said reservoir is moved axially in the body without inhalation.

    In the description, the terms "upper", "lower", "high" and "low" refer to the position of the device shown in particular in FIG. 1. The terms "axial" and "radial" refer to the axis vertical central A shown in particular in Figure 1. The terms "proximal" and "distal" refer to the mouthpiece. The invention is more particularly applicable to aerosol valve type inhalation devices for oral delivery, as will be described in more detail below, but it could also be applicable to other types of devices. inhalation, for example of the nasal type.
    The figures represent several advantageous embodiments of the invention, but it is understood that one or more of the component parts described below may be performed differently while providing similar or even identical functions.
    With reference to the drawings, the device comprises a main body 10 provided with a mouthpiece 400. This mouthpiece 400 defines a dispensing orifice through which the user will inhale during use of the device. A removable protective cover 410 may be provided on said mouthpiece 400, especially during storage periods, that the user will remove before use. Figures 1, 8 and 9 show such a protective cover, which could be of any shape.
    The body 10 contains a reservoir 100, containing the product to be dispensed and a propellant, such as an HFA type gas, a metering valve 200 being mounted on said reservoir 100 to selectively distribute the product. The metering valve 200 comprises a valve body 201 and a valve 210 axially displaceable upon actuation with respect to said valve body 201, and thus with respect to said tank 100. This metering valve 200 may be of any suitable type. It can be fixed to the reservoir 100 by a fixing element, preferably a crimped capsule 5, preferably with the interposition of a neck seal 4.
    Advantageously, during actuation, the valve 210 is fixed relative to the body 10, and it is the reservoir 100 which is displaced axially relative to the body 10 between a distal position, which is the rest position, and a position proximal. The outlet port of the valve 210 of said metering valve 200 is connected via a channel 300 to said mouthpiece 400, through which the user inhales the dispensed product. In known manner, said valve 210 is received in a valve well 700 which at least partially defines said channel 300. In the embodiments of FIGS. 1 to 9, the valve well is formed integrally with the body 10, whereas in the embodiments of FIGS. 14 to 19, said valve well is axially displaceable with respect to said body 10.
    According to the invention, the device comprises an actuating element 500, 500 ', 550 displaceable and / or deformable between a non-actuating position, in which said metering valve 200 can not be actuated, and an actuating position, wherein said metering valve 200 can be actuated. In the rest position, said actuating element 500, 500 ', 550 is in the non-actuating position, and it is the inhalation of the user through the mouthpiece 400 which displaces and / or deforms the said element. actuating 500, 500 ', 550 to its actuating position. In other words, as long as the user has not inhaled, the actuation of the metering valve 200 is impossible, and it is only when he inhales that he can actuate said metering valve 200, advantageously by manual support on the bottom of the tank 100.
    As will be described in more detail below, the actuating element may be a locking element 500, 500 'which, in the non-actuating position, prevents the axial displacement of the reservoir 100 in the body 10. inhalation, this blocking element 500, 500 'is displaced and / or deformed so that it no longer blocks the axial displacement of the reservoir 100 in the body 10. Thus, after inhalation, such axial displacement of the reservoir 100 causes the actuation of the metering valve 200 and the distribution of a dose of product synchronized with this inhalation.
    In a variant, as will be described with reference to FIGS. 14 to 16, the actuating element may be a locking element 550 which, in the non-actuating position, allows axial displacement of the valve 210 of the metering valve 200 together. with reservoir 100 in the body 10, thereby preventing the actuation of said metering valve 200 when said reservoir 100 is moved axially in the body 10 without inhalation. Upon inhalation, this locking member 550 is moved and / or deformed such that it blocks the axial displacement of the valve 210 relative to the body 10. Thus, after inhalation, an axial displacement of the reservoir 100 causes the actuating the metering valve 200 and dispensing a dose of product synchronized with this inhalation.
    Thus, in the two variants described above, in the absence of inhalation, there is no risk that a dose of active product is lost by an unfortunate or incomplete operation in which the user would not exercise. inhalation. The actuation of the valve 200 and the expulsion of a dose of fluid product are therefore possible only if the user inhales and simultaneously presses the reservoir 100 to actuate the valve 200.
    The device comprises a triggering system controlled by the inhalation of the user, which is intended to move and / or deform said actuating element 500, 500 ', 550 from its non-actuating position to its actuating position, when the user inhales through the mouthpiece 400.
    This trigger system comprises an organ sensitive to inhalation 60, 65, deformable and / or displaceable under the effect of inhalation, this inhalation-sensitive organ 60, 65 being adapted, when it deforms and / or moves, displaces and / or deforms said actuating element 500, 500 ', 550 from its non-actuating position to its actuating position.
    As will be described in more detail hereinafter, the inhalation sensitive member may be embodied as a deformable air chamber 60, for example a bellows or a deformable pocket.
    In a variant, as will be described with reference to FIGS. 14 to 19, the organ sensitive to inhalation may be in the form of a piston 65, preferably cylindrical, sliding in a chamber 66, preferably cylindrical, no deformable.
    According to a first embodiment, represented in FIGS. 1 to 13, the non-actuating position corresponds to a blocking position of the reservoir 100 in the body 10. In this blocking position, the reservoir 100 is prevented from moving by said actuating element, which will be released only at the time of inhalation.
    The body 10 is shown in particular in Figure 10. Of course, the form shown is not limiting. The actuating element, forming a blocking element, is here advantageously formed by a locking ring 500, comprising at least one, preferably three axial locking tabs 501, which are elastically deformable radially outwardly. FIG. 11 represents a perspective view of this locking ring 500. This locking ring 500 is fixed, in particular latched, on the tank 100, in particular on the cap 5 which fixes the metering valve 200 on the tank 100. 501 block rest in the rest position on a radial shoulder 710 of said valve well 700. This shoulder is preferably inclined downwardly and radially outwardly, so that when the reservoir 100 slides axially in the body 10 when upon actuation, said axial locking tabs 501 slide on said inclined shoulder 710, which deforms them radially outwardly.
    A trigger element 600 is mounted to slide axially around said valve well 700 between a locking position, in which it blocks said locking ring 500 in its non-actuating position, and a release position, in which it no longer blocks said ring. In particular, in the embodiment of FIGS. 1 to 13, said trigger element 600, in the locked position, cooperates with said locking tabs 501, preventing any radially outward deformation of said locking tabs 501. Thus, when said trigger element 600 is in the locking position, it prevents radial outward deformation of said locking tabs 501, which consequently remain axially locked by said shoulder 710 of the valve well 700, which blocks the axial displacement. of the tank 100 and therefore the actuation of the metering valve 200. Optionally, sliding means, such as balls, for It should be interposed between the valve well 700 and the trigger element 600 to facilitate sliding of the latter during inhalation. The trigger element 600, more particularly visible in FIG. 12, advantageously comprises a hollow central sleeve 650 which slides axially around the valve well 700 and two diametrically opposed axial tabs 660, each connected to said central sleeve 650 by a radial spacer. 670. These axial tabs 660 each cooperate with a respective opening 13 of the body 10, to substantially close these openings 13 in the locking position, and to substantially open these openings 13 in the release position. These openings 13 being closed at the beginning of inhalation, the inhalation flow is initially mainly transmitted to the triggering system by inhalation, in this example the deformable air chamber 60. This optimizes this triggering by the inhalation. When the trigger element 600 has moved axially towards its release position under the effect of inhalation, and therefore when the user can actuate the metering valve 200 to dispense a dose of fluid product, the axial tabs 660 open. said openings 13 of the body 10, which generates a call for air, and therefore increases the inhalation flow. This optimizes the synchronization between the dose distribution and the user's inhalation, and promotes a good distribution of the dose in the lungs of the user.
    Advantageously, said axial tabs 660 are accessible from the outside through said openings 13. This makes it possible, if necessary, to manually move the trigger element 600, in order to be able to actuate the metering valve 200 even without inhalation, for example if the person to receive the dose of fluid is unable to achieve sufficient inhalation. It is therefore a security. As a variant for this security, it would be possible to provide an axial extension (not shown) integral with the trigger element 600, extending for example laterally from the tank 100, and accessible by the user from outside the body 10.
    Advantageously, as can be seen in FIG. 2, said axial lugs 660 cooperate with a first shoulder 14 of the body 10 to define the locking position of the trigger element 600, forming an axial abutment which prevents said trigger element 600 from rising towards the high beyond this blocking position. Similarly, as can be seen in FIG. 5, said axial lugs 660 cooperate with a second shoulder 15 of the body 10 to define the release position of the trigger element 600, forming an axial abutment which prevents said trigger element 600 from descending towards down beyond this release position.
    Alternatively (not shown), the trigger element 600 may not include the axial lugs 660, and the body would then not include the openings 13. In this case, the inhalation flow could flow axially in the body, around the valve well, which could be favored by a central sleeve 650 provided with axial cuts allowing the flow of air.
    In the embodiment of Figures 1 to 13, the inhalation sensitive member 60 is constructed as a deformable air chamber. Advantageously, this air chamber comprises a deformable membrane 61 which is connected on the one hand to the body 10 and on the other hand to said trigger element 600. Advantageously, as shown in FIGS. 1 to 9, a membrane-holding sleeve 800 is fixedly disposed in the body 10, with a lower shoulder 810 which wedges a first edge 62 of the membrane 61 against a portion 17 of the body 10. The second edge 63 of the membrane 61 can be fixed in a groove 630 of the trigger element 600, advantageously formed on the hollow central sleeve 650 thereof. FIG. 13 illustrates a cutaway view of a bellows-shaped membrane, but other shapes are possible, in particular a simple pocket or diaphragm, as can be seen in FIG. 8.
    Upon inhalation, the deformable membrane 61 deforms and / or contracts under the effect of the depression generated by inhalation, causing the trigger 600 to move from its blocking position to its release position. This then allows the radial deformation of said locking tabs 501 and thus the displacement of said locking ring 500 forming the actuating element from its non-actuating position to its actuating position. Figures 1 to 7 show a deformable membrane 61 made in the form of a bellows, and Figure 8 shows a variant in which the deformable membrane is made in the form of a pocket or a diaphragm. Of course, other forms are also conceivable.
    The valve 200 is therefore actuated at the time of inhalation, so that the fluid dose is expelled out of the dispensing orifice simultaneously with the inhalation.
    When the user wishes to use the device, he places the mouthpiece 400 in his mouth, and manually presses on the bottom of the reservoir 100, that is to say the upper surface of said reservoir 100 in the position of the figures. The reservoir 100 will then be blocked and prevented from sliding in the body 10 by the locking tabs 501 of the locking ring 500, which rest on the shoulder 710 of the valve well 700. Optionally, the reservoir 100 can make a small stroke d1 before being blocked, this small initial race d1 being however insufficient to operate the metering valve 200. Figure 1 shows the device at rest and Figure 3 shows the device in the reservoir blocking position 100, after that this one realized this small initial race d1.
    When the user inhales through the mouthpiece 400, it will deform the deformable membrane 61, which will slide the trigger element 600 attached to said deformable membrane 61, as shown in Figure 4. This displacement of the trigger element 600 on the valve well 700 will radially release the tabs 501 of the locking ring 500. Under the effect of the axial force transmitted by the reservoir 100, generated by the user pressing against the bottom of said reservoir 100, the axial lugs 501 will be able to deform radially outwards, and thus pass over said shoulder 710, to allow the sliding of the reservoir 100 to its dispensing position, and therefore the actuation of the valve 200. This position of distribution is shown in Figures 5 and 6.
    At the end of inhalation, the trigger element 600 is brought upwards by the elasticity of the membrane 61. FIG. 7 illustrates the position where the trigger element 600 was brought back by said membrane 61, but before the user releases its pressure on the tank 100.
    When the user releases its pressure on the bottom of the tank 100, it returns towards the rest position under the effect of the return spring of the valve 200, and simultaneously the valve 210 of the metering valve returns to position resting, loading a new dose of fluid into the valve chamber. The device is then ready for another use.
    FIG. 9 illustrates an alternative embodiment of the embodiment of FIG. 8, embodying electronic modules.
    In particular, there is provided an electronic dose counter 1000, advantageously assembled on the body 10. This counter 1000 can in particular detect the movements of the reservoir 100, for example by means of a contact sensor 1010. Alternatively, the counter 1000 could be connected to a sensor, in particular a membrane sensor, which detects the distribution of the dose of fluid product, for example in the valve well 700. Other means of actuating the electronic counter 1000 are also possible, for example detecting the displacement of the valve 210 of the metering valve relative to the valve body 201.
    Preferably, the device also comprises signal transmission means 1100 for remote communication including information relating to the actuations of the device. In particular, the body 10 may comprise a signal transmission module for remote communication with any base. Suitable feeding means are advantageously provided.
    Advantageously, the electronic module may comprise in particular a card comprising an electrical switch which sends a pulse. The module may also include a display and / or use a Bluetooth or Wifi connection to send the information to a peripheral device. Suitable sensors may be provided, such as flow rate and / or pressure sensors, to detect various parameters of the inhalation flow.
    Associated with a dose counter 1000 which counts each dose actually emitted and the synchronization device with the inhalation of the invention, these signal emitting means 1100 make it possible to transmit in an absolutely reliable manner each dose distribution, for example to a physician or other person wishing to monitor the use of the inhalation device by the user. The synchronization device with inhalation ensures that the user inhales each time he actuates the device, and the meter records each dose dispensed, as well as various associated parameters, such as the timestamp of each distribution. The doctor can thus know exactly the conditions of use of the device by the user.
    Figures 14 to 16 illustrate another embodiment of the invention. Here, the actuating element is a locking element 550 which, in the non-actuating position, allows the axial displacement of the valve 210 of the metering valve 200 together with the reservoir 100 in the body 10, preventing the actuation of said metering valve 200 when said reservoir 100 is axially displaced in the body 10 without inhalation. Upon inhalation, this locking member 550 is moved and / or deformed such that it blocks the axial displacement of the valve 210 relative to the body 10. Thus, after inhalation, an axial displacement of the reservoir 100 causes the actuating the metering valve 200 and dispensing a dose of product synchronized with this inhalation. The organ sensitive to inhalation is in the form of a piston 65 sliding in a chamber 66 between a rest position and an inhalation position. The chamber 66 is advantageously formed in the mouthpiece 400. Said piston 65 is connected to said locking element 550, advantageously by a rod 540. In particular, as shown in FIGS. 14 to 16, the locking element 550 is formed at the end of said rod 540 opposite said piston 65, and comprises an axial projection 551. A spring 67, advantageously disposed in the chamber 66, is adapted to return said piston 65 towards its rest position when there is no more inhalation through the mouthpiece 400.
    In the non-actuating position, said projection is offset radially with respect to the valve well 700, so that it can move axially in the body 10, together with the valve 210 of the metering valve 200 and the reservoir 100. Thus in this non-actuating position, the valve 210 moves relative to the reservoir 100, and the metering valve 200 is not actuated.
    When the user inhales through the mouthpiece 400, the piston 65 moves radially (relative to the axis of displacement of the reservoir 100 in the body 10) in the chamber 66 under the effect of the depression created by the 'inhalation. Projection 551 thus also moves radially, and is positioned under said valve well 700, thereby forming an abutment to axial downward movement of said valve well. Therefore, the pressure exerted by the user on the bottom of the tank 100 will move it axially downwards in the body, and the valve well 700, now axially fixed relative to the body 10, will therefore block the valve 210 of the metering valve axially relative to the body 10, so that it will sink into the valve body, thereby causing the actuation of the metering valve 200 and the dispensing of a dose of fluid.
    The device shown in FIGS. 14 to 16 may also comprise electronic means, such as those described above in relation with FIG. 9. They will therefore not be described again here. Of course, in this embodiment where the reservoir 100 is axially displaceable in the body 10 both in the actuating position and the non-actuating position of the actuating element 550, the dose counter 1000 can not measure this displacement. In this case, preference will be given to sensors detecting the distribution of the fluid product, in particular in the valve well 700, or sensors detecting the displacement of the valve 210 of the metering valve 200 with respect to the valve body 201.
    Figures 17 to 19 illustrate yet another embodiment. Here, the triggering system by inhalation is similar to that described above with reference to Figures 14 to 16, with a piston 65 sliding radially in a chamber 66 of the mouthpiece 400.
    Here, the actuating element is again made in the form of a locking element 500 ', which, in the non-actuating position, prevents the axial displacement of the reservoir 100 in the body 10. During inhalation, this locking element 500 'is displaced and / or deformed so that it no longer blocks the axial displacement of the reservoir 100 in the body 10. Thus, after inhalation, such axial displacement of the reservoir 100 causes the actuation of the metering valve 200 and the distribution of a dose of product synchronized with this inhalation.
    This locking element 500 'can in particular be assembled on said rod 540 integral with the piston 65, and include an axial extension 505 which, in the non-actuating position extends axially in the body to cooperate with and axially lock said reservoir 100. When the user inhales, the rod 540 moves radially to the left (in the orientation of the figures), which will cause the deformation of said axial extension 505, and thus release the axial displacement of the tank 100. In the example shown , the valve well 700 is movably mounted in the body 10, but it could also be fixed.
    Advantageously, the lower end 506 of said axial extension 505 is fixed radially and axially relative to the body 10. Thus, when the rod 540 moves radially, it pulls radially on said axial extension, which deforms, for example bends or rotates, so that the upper end disengages the tank 100 and releases it for its axial displacement. Of course, the blocking element 500 'could have any other suitable form. In particular, one can consider the use of an articulated toggle.
    FIG. 19 represents an alternative embodiment, in which the rod 540 is accessible from outside the body 10 through an opening 19 of said body 10. This makes it possible, if necessary, to manually move the locking element 500 ', so as to to be able to actuate the metering valve 200 even without inhalation, for example if the person to receive the dose of fluid product is unable to achieve sufficient inhalation. It is therefore a security. It should be noted that this security could also be adapted to the embodiment of FIGS. 14 to 16.
    The device shown in FIGS. 17 to 19 may also comprise electronic means, such as those described above in relation to FIG. 9. They will therefore not be described again here.
