Definitions
- Fluid product distribution device of the single-dose or bidose type of the single-dose or bidose type
- the present invention relates to a fluid product distribution device and more particularly to a fluid product distribution device of the single-dose or two-dose type, that is to say containing a dose or two half-doses of product to be distributed.
- single-dose or two-dose devices are often used to dispense drugs intended to be taken in a single dose, such as vaccines or emergency drugs, and sometimes these devices are not intended for self-administration by the patient but on the contrary to be distributed by a third person to a patient.
- no satisfactory solution has really been proposed to simultaneously resolve these aspects of security and reliability.
- the existing devices are generally formed by two elements, one supporting the reservoir and the other supporting the piston.
- the first half dose When compressed axially towards each other, the first half dose is ejected through the dispensing orifice into the nostril.
- the stroke of the piston In order to divide the dose, the stroke of the piston is stopped at half its length by a shoulder, and to carry out the second part of the stroke, i.e. distribute the second half-dose, it is necessary to rotate manually the piston element with respect to the reservoir.
- This type of system is safe and precise but requires relatively complex handling, and therefore the use of two hands to obtain the result and to be able to distribute the two half-doses successively in the two nostrils.
- the existing devices do not offer a solution.
- these devices require a pressure exerted axially towards the nostril and this is relatively difficult to achieve due to the relatively small dimension of this type of device, this being particularly important in the case of administration carried out by a third person.
- the axial pressure necessary to actuate the device can cause the device to move inside the nostril and cause injury and even a risk of poor dose distribution due to a reaction by the patient, for example by a sudden backward movement at the time of distribution.
- Document US Pat. No. 5,570,821 discloses a pasty product dispenser comprising a rack associated with the piston, said rack being moved vertically by means of a lateral actuation button.
- the object of the present invention is to provide a device for dispensing a fluid product which does not have the abovementioned drawbacks.
- the present invention aims to provide a fluid dispensing device which is ergonomic and easy to use, regardless of its small dimensions, even by a third person.
- the present invention also aims to provide a device for dispensing a fluid product which ensures in a simple, safe and reliable manner the division of the dose into two half-doses, in the case of a bidose device, and which does not require using two hands to dispense the two half doses into the two nostrils.
- the present invention also aims to provide a fluid dispensing device which is simple and economical to manufacture and assemble.
- the present invention therefore relates to a fluid dispenser device comprising a body, a reservoir unit comprising a reservoir containing a dose or two half doses of product, a dispensing member such as a piston displaceable axially in the reservoir between a rest position and a dispensing position, and an actuating element movable between a rest position and an actuating position, characterized in that said actuating element is arranged laterally and has an end portion provided with a cam surface cooperating with said dispensing member or said reservoir unit, the displacement of said actuating element being carried out in a different direction, and in particular approximately perpendicular, to the direction of axial displacement of the dispensing member relative to the tank.
- a dispensing member such as a piston displaceable axially in the reservoir between a rest position and a dispensing position
- an actuating element movable between a rest position and an actuating position
- the lateral actuating element is slidably mounted in said body and moves in translation.
- said lateral actuating element is pivotally mounted on said body, and moves in rotation around a pivot axis.
- the reservoir contains a single dose of product, the dispensing member or the reservoir unit comprising at least one projection cooperating with said cam surface of said actuating element.
- the reservoir contains two half-doses of product, the device comprising dose fractionation means.
- the actuating element comprises elastic return means which bring it back to its rest position after expulsion of the first half-dose, and the dose-splitting means are produced so that the second half-dose is expelled when the actuating member is again moved to its actuating position.
- the dispensing member or the reservoir unit comprises at least two axially offset projections, at least one first projection cooperating with the cam surface to expel the first half dose and at least one second projection cooperating with the cam surface. to expel the second half dose.
- said at least one second projection is provided on an elastic arm secured to the dispensing member or to the reservoir unit, said arm moving apart when the actuating element cooperates with said at least one first projection to expel the first half dose and returning elastically to its initial position when the actuating element is returned to its rest position by the elastic return means, after expulsion of the first half dose, so that said at least one second projection cooperates with the cam surface of said actuating element when the latter is moved again to its actuating position to expel the second half-dose.
- said cam surface of the actuating element is an inclined plane transforming an approximately radial displacement of the actuating element into an axial displacement of the dispensing member or of the reservoir unit.
- said actuating element is made in one piece with said body, a bridge of flexible material forming the pivot axis.
- the reservoir unit is fixed relative to said body, said actuating element cooperating with said dispensing member.
- the dispensing member is fixed relative to said body, said actuating element cooperating with said reservoir unit.
- FIG. 1 is a diagrammatic view in cross section of a device for dispensing a fluid product according to a first embodiment of the invention
- FIG. 2 is a view similar to that of FIG. 1, after the expulsion of a first dose
- FIGS. 3 and 4 are schematic views in horizontal section seen from above of the device of Figures 1 and 2
- - Figure 5 is a schematic view of a second embodiment of the invention, in the rest position
- FIG. 6 is a view similar to that of FIG. 5, after expulsion of a dose
- Figure 7 is a schematic view similar to that of Figures 5 and 6, showing an embodiment of the bidose type.
- the device comprises a main body 1 which supports a nose piece 2 incorporating the dispensing orifice.
- a reservoir unit 3 comprising a reservoir containing a dose or two half-doses of product, is fixed in said body 1.
- the body 1 is in addition provided with a hollow side sleeve 4 in which slides an actuating element 5, such as a push button.
- the actuating element 5 is provided with a surface of cam 6, preferably made in the form of one or more inclined planes.
- a dispensing member 8, such as a piston, is slidably mounted inside the tank and moves between a rest position shown in FIG. 1 and an expulsion position, the movement being carried out axially inside of said reservoir.
- the cam surface 6 of the actuating element 5, in particular the inclined planes, cooperates with at least one, preferably two projections 7, which are formed on the piston element 8.
- This pair of projections 7 is inserted and can slide in two grooves 9 which are formed in the wall of the cavity 10 of the body 1 in which the piston 8 slides during its actuation.
- the actuating element 5 can also be provided with retention means 11, which prevent the actuating element from being accidentally withdrawn from the body, and with elastic return return means, which are not shown in the drawings.
- the piston 8 also includes a second pair of projections 12, which are advantageously formed on two elastic arms 13 which form part of the piston 8.
- the projections 12 are advantageously provided with thickening 14 in the direction of the upper part of the device.
- the invention is not however limited to the device of the bidose type, and can also be applied to devices of the single dose type, in which a single dose must be expelled.
- the operation is similar to that described above, with the difference that there is only a pair of projections 7 provided on the piston 8, the projections 12 and the arms 13 being in this case useless. , as well as the elastic return means.
- FIGS. 5 to 7 a second embodiment of the invention is shown, in which the actuating element 5 is not slidably mounted inside the body 1, but is pivotally mounted on said body 1
- the operation of the device is relatively similar to that described above, the shape of the cam surface 6 being of course adapted to the rotational movement effected by the actuating element 5.
- FIGS. 5 and 6 clearly show the position of rest and the actuation position for a single-dose type device.
- FIG. 7 represents the above embodiment for a device of the bidose type, for which the operation is similar to that described above, namely that a second pair of projections 12 is provided on the piston 8, said projections s' discarding when the actuating element 5 is actuated to expel the first half-dose, and then returning to the position corresponding to the initial position of the first projections 7, for the expulsion of the second half-dose.
- the actuating element is made in one piece with the body 1 and connected to the latter by a material bridge which forms the pivot axis 20.
- energy storage means can be provided on the actuating element 5 or on the body 1, for example in the form of a lug or the like.
- the angle of inclination of the inclined plane 6 can also be determined so as to achieve a reduction in the force exerted by the actuating element on the piston or the reservoir.
- the lateral actuating element can also cooperate with the reservoir unit, which in this case incorporates the first and / or second projections. It is then the piston which is fixed relative to the body of the device and the reservoir which is moved axially by the lateral actuating element.
- the invention therefore provides a device of the bidose or monodose type, which makes it possible to distribute the product inside the nostril while keeping the device axially fixed inside the nostril at the time of the expulsion of the product, no force. axial being exerted on the device at this time.
- actuation of the device is very easy for a third person, since there is no risk of injuring the patient.
- the device can be operated with one hand, which is a very important advantage, while guaranteeing safe and reliable operation each time the device is actuated.
