Description

[0035] For this purpose, the device is now described with respect to the accompanying drawings, drawings in which the various figures show:

[0036] FIG. 1: A perspective view of a delivery device according to this invention,

[0037] FIG. 2: A longitudinal cutaway view of the device of FIG. 1,

[0038] FIG. 3: A view of the connecting means of the cartridges used in the delivery device of FIG. 1,

[0039] FIG. 4: A view of the cartridges used for employing the delivery device according to this invention.

[0040] FIG. 1 shows a straw 10 that comprises a body 12, means 14 for accommodating at least one cartridge 16, and display means 18.

[0041] The body 12 comprises two elements that are linked together in a monolithic manner. The first element 20 is a plunger, and the second element 22 pertains to the mouth.

[0042] The first element 20 comprises, in a known way, a cylindrical, hollow, tubular portion 24, whose diameter is compatible with the flow envisioned, on the order of 2 to 5 mm.

[0043] The second buccal element 22 comprises a hollow housing 26 that is designed to accommodate at least one cartridge 16.

[0044] This second buccal element 22 is open at the top in such a way as to make it possible to be taken by mouth at least by a child.

[0045] This second buccal element 22 should therefore have dimensions that are also adapted to the mouth of a child, on the order of 8 to 10 mm.

[0046] The hollow housing 26 is connected to the first element 20 and is in direct communication with the cylindrical, hollow, and tubular portion 24.

[0047] Thus, the straw 10 is open at its two ends, and a continuous longitudinal central channel of the axis XX passes through it.

[0048] Each cartridge 16, in the adopted embodiment, is of cylindrical, hollow shape, open at its two ends.

[0049] As also shown in FIGS. 2 and 3, each cartridge 16 comprises a soluble product 28, in particular at least one pharmaceutical active ingredient, introduced in solid form in said cartridge 16.

[0050] This active ingredient is integrally soluble in a liquid, in this case in water.

[0051] So as not to ingest the solid powder directly before solubilization as previously explained in detail, a filter 30 is advantageously provided at each of the two ends of said cartridge.

[0052] Each cartridge 16 and/or the communication tube comprise(s) a connecting head 32. This connecting head 32 makes possible a fluidtight connection either with the device itself or with another cartridge.

[0053] The display means 18 comprise a communication tube 34, an index 36, and sealing means 38.

[0054] The communication tube 34 is arranged in the cylindrical, hollow, tubular part 24 of the first element 20. This communication tube 34 can slide into said hollow cylindrical part 24.

[0055] The communication tube 34 extends into the hollow housing 26 of the second buccal element 22 into which it also slides.

[0056] The index 36 is integral with the end of the communication tube 34 and more particularly with the end located in the hollow housing 26.

[0057] The sealing means 38 comprise an O-ring seal 40, inserted between the inside wall of the cylindrical, hollow, tubular part 24 of the first element 20 and the outside wall of the communication tube 34.

[0058] In an advantageous way, the straw 10 is produced from a transparent or at least translucent material; the index 36 is of such a color to make it possible to see it.

[0059] In addition, graduations 42 are made on the wall of the second buccal element 22. These graduations 42 are in particular weight graduations that correspond to ranges of weight of a child, in this case 10, 20, 30 kg.

[0060] In the embodiment shown, it is noted that the second buccal element 22 is provided for accepting at most three cartridges 16, each cartridge 16 making it possible to deliver the dose of active ingredient per 10 kg.

[0061] In an advantageous way, means 44 are provided for holding the cartridges after insertion within the hollow housing 26 of the second buccal element 22. These means can be of any nature whatsoever and in particular in the form of a flexible lug 46 that remains flattened against the outside wall of the cartridge 16 in one direction.

[0062] In the other direction, this lug 46 rises and presses against the wall of the hollow housing 26 and more particularly against an inside lip 48, made for this purpose in said hollow housing, forming a stop and preventing the extraction of said cartridge 16.

[0063] The operation of the device is as follows:

[0064] When an active ingredient is to be administered in particular to a child, based on weight or on the prescription, the individual responsible for administering the active ingredient selects the necessary number of cartridges 16.

[0065] In this regard, the cartridges can advantageously be presented in the form shown in FIG. 4. This is a packaging 50 in the form of a series of cartridges 16. This series can be flexible so as to make possible a winding in a ring. In this case, the packaging material will be a flexible or semi-rigid material.

[0066] The series is separable so as to make possible a sampling of 1, 2 or 3 cartridges in the case shown. These cartridges are then integral with one another.

[0067] In this case, it is necessary to use only a single connecting head 32 that is already integrated on the end of the communication tube 34.

[0068] When the user has sampled the number of cartridges corresponding to the weight of the child, in this case two cartridges, for example, for a child of 20 kilos, said cartridges are inserted into the hollow body 26.

[0069] The cartridges 16 penetrate and come into contact with the connecting head 32; the end of the first cartridge is fitted on in a fluidtight manner.

[0070] The O-ring seal 40 of the sealing means 38 ensures sufficient resistance to ensure this fitting.

[0071] The two cartridges 16 are inserted integrally, and the holding means 44 in the form of lugs 46 ensure clamping, in the direction of the withdrawal, because of the lip 48.

[0072] Depending on the pressure exerted with the thumb, for example, by the user on the cartridges, the communication tube 34 slides in translation in a fluidtight manner in the first cylindrical, hollow and tubular portion 24 of the first element 20.

[0073] The index 36, integral with said communication tube 34, also moves in the hollow part 26 of the second buccal element 22, and the patient can have confirmation by reading graduations 42 that the announced weight is indeed that of the child and therefore that the number of cartridges indeed corresponds to this weight.

[0074] The patient then immerses the free end of the first cylindrical, hollow and tubular portion 24 of the first element 20 in the liquid contained in a glass, for example.

[0075] He brings the free end of the second buccal element 22 to his mouth and sucks.

[0076] The liquid that is contained in the glass, subjected to a partial vacuum, moves into the first cylindrical, hollow and tubular portion 24 of the first element 20 and then abuts the O-ring seal that leads it into the communication tube 34; the liquid continues its movement through the two cartridges 16.

[0077] It dissolves the active ingredient or ingredients and the flavoring and/or solubilization excipients contained in said cartridges, in the form of powder, balls, or any other solid galenical form.

[0078] The liquid that is loaded with this or these active ingredient(s) is then absorbed by the patient.

[0079] Multiple improvements are possible.

[0080] The cartridges can comprise a dye making it possible to note the change in color when the entire active ingredient is dissolved and therefore absorbed.

[0081] In some cases, the soluble product in terms of this invention can also be partially soluble.

[0082] According to a variant, the solid active ingredient can be carried by an inert medium that remains in the cartridge, with only the active ingredient being soluble during the passage of the fluid in said cartridge.

[0083] The filter 30 that is provided in the embodiment has as its objective to hold the active ingredient(s) in solid form in said cartridges.

[0084] In a way that is also not to pollute the liquid contained in the glass, it is possible to use anti-return means in the form of a non-return valve in the communication tube; for example, a flexible membrane or a ball are quite suitable means.

[0085] In the same way, the embodiment shown was within the framework of a non-reusable device.

[0086] This invention certainly includes the option that the device can be reused. In this case, the holding means should be provided to make possible a voluntary withdrawal.

[0087] The device is then emptied of its cartridges and reused, after rinsing, with new cartridges.
