Definitions
- the present invention relates to a device for packaging and metering an ophthalmic treatment liquid.
- the devices traditionally used for ophthalmic treatments generally consist of a reservoir equipped with a simple pipette for the collection and application in manual mode and drop by drop of the eye drops on the eye to be treated.
- volume of a drop which is determined by physical laws is always between 25 and 50 microliters (which corresponds to a diameter between 1.81mm and 2.28mm) and it is not possible to fractionate this drop to deliver a lower dose.
- the aim of the present invention is to solve the technical problems linked to the prior art by using an ophthalmic liquid sprayer.
- a device for packaging and dosing an ophthalmic treatment liquid of the type comprising in particular a reservoir equipped with a pump and a nozzle producing a cone of sprayed liquid. , characterized in that it further comprises, a telescope intended to be applied to the eye to be treated and which is partially closed by a diaphragm capable of being arranged across the cone of sprayed liquid.
- said bezel is articulated by means of a hinge whose position is fixed relative to the nozzle.
- said hinge is arranged so that the telescope can switch between a rest position where it covers the reservoir by forming a cover and a treatment position where it extends laterally forming a viewfinder with the diaphragm across the cone of sprayed liquid.
- the contours of the opening of the diaphragm are elliptical and its dimensions are less than or equal to those of the eye to be treated.
- the diaphragm is produced in an internal partition with a curvilinear profile of the bezel.
- the reservoir is removably housed in a housing carrying the bezel.
- the cross section of the telescope is identical to that of the housing, and the proximal edge of the telescope has a profile adapted to the upper edge of the housing to allow contiguous connection.
- the housing includes a setting element for the telescope to maintain the diaphragm across the cone of sprayed liquid, and if necessary, it has a lateral column carrying the telescope.
- the distal edge of said telescope comprises a peripheral rib intended to come to bear on the periphery of the eye to be treated.
- said bezel includes locking means on the tank.
- the device of the invention makes it possible to refine the dosage of the eye drops since the dimensions of the droplets of a jet of sprayed liquid vary between 10 and 150 micrometers or 20 to 200 times smaller than those of a drop.
- the volume - elementary liquid sprayed by a short operation of the pump can go down to 2 microliter, which corresponds to a dose whose volume is one tenth of a drop.
- the diaphragm also allows the dosage to be adjusted by letting only a fraction of the sprayed volume pass to the eye. Furthermore, the device of the invention allows comfortable use since it is no longer necessary either to arrange the eye in a horizontal plane or to aim the eye while dropping the drops.
- FIG. 1 shows a perspective view of an embodiment of the device of the invention in the position of use for treatment
- FIG. 2 shows a perspective view of the embodiment of Figure 1 in the rest position of the telescope
- FIG. 3 shows a sectional profile view of the embodiment of Figures 1 and 2 in the rest position
- - Figure 4 shows a profile sectional view of the embodiment of Figures 1 and 2 in the position of use for treatment
- FIG. 5 shows a top view of the device of the previous figures in the rest position.
- the device shown in Figures 1 and 2 is intended to condition and dose an eye drop in order to practice ophthalmic treatments by applying the eye drops to the surface of the eye.
- This device comprises a sealed reservoir 1 containing the eye drops.
- the reservoir 1 is equipped with a pump 2 of which only the upper part is visible in FIG. 1.
- the pump 2 is provided in particular with a spray nozzle 20 associated with a nozzle tube 21
- this device further comprises a telescope 3 intended to be applied to the eye to be treated by surrounding the ocular cavity in the manner of an eyepiece.
- the telescope 3 consists of a short section of tube of elliptical section partially closed off by an internal partition 31 with diaphragm 30.
- the diaphragm 30 has a central opening 30a whose surface is constant and whose elliptical contours have smaller or equal dimensions to those of the eye to be treated.
- the internal partition 31 on which the opening 30a of the diaphragm 30 is formed has a convex curvature in the direction taken from the telescope 3 towards the nozzle 20.
- the telescope 3 with its diaphragm 30 is arranged across the eye drop jet delimited by a cone C of sprayed liquid.
- the cone C produced by the nozzle 20 during the operation of the pump 2 thus meets the convex face of the partition 31. Under these conditions, only a fraction of the spray of liquid spray passes through the opening 30a of the diaphragm 30 in the direction of the eye while the complementary fraction is stopped by the full partition.
- the distance between the nozzle 20 and the opening 30a as well as the surface of said opening therefore determine the dose of eye drops actually applied to the eye.
- the distance between the nozzle 20 and the diaphragm 30 depends on the position of the telescope 3.
- the hinge 4 is, for example, a snap hinge, adapted and arranged so that the bezel 3 can switch between a rest position ( Figures 2 and 3) or it covers the tank 1 by forming a cover or cover and a treatment position ( Figures 1 and 4) where it extends laterally forming a viewfinder.
- the diaphragm 30 is placed crosswise and, preferably, inside the spray cone C.
- the reservoir 1 is optionally and removably housed in a compartment 50 formed inside a housing 5 carrying the hinge 4 and the bezel 3.
- the cross section of the bezel 3 is here identical to that of the housing 5 so as to form in the rest position ( Figures 2 and 3) a nearly perfect cylinder.
- the proximal edge 33 of the telescope 3 which is located on the side of the nozzle 20 ensures, by a profile adapted to the upper edge of the housing 5, a contiguous connection with said housing.
- the proximal edge 33 is further provided with means for locking the telescope 3 in its rest position.
- These locking means consist, for example, of a tongue or a lug 35 intended to snap reversibly into a corresponding cavity formed on the upper face of the housing 5.
- the distal edge of the telescope 3, which is situated on the side opposite to the nozzle 20, is provided, for its part, with a protruding rib 34 intended to come to bear on the periphery of the eye or the ocular cavity , during processing.
- the housing 5 has an external lateral column 51 carrying, on the one hand, the hinge 4 and therefore the bezel 3 and, on the other hand, an element for wedging the bezel 3 in its lateral treatment position.
- This wedging element is preferably made in the form of a rib 52 arranged across the upper face of the column 51 parallel to the axis of the nozzle 20.
- the rib 52 is intended to engage, in position for processing the telescope 3, in a groove 32 of complementary profile which is formed on the wall opposite said telescope.
