DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0034] In FIG. 1, 1 denotes, as a whole, a veterinary medical device that can be successfully used to remove food residues and calcium deposits from rigid and/or soft surfaces from the mouths of animals, preferably but not limited to dogs, and deposits of substances colonizable by pathogens. With particular reference to FIG. 5, this device 1 comprises a rod 10 produced by moulding plastic material and elongated according to a given D direction. With reference to FIGS. 1-4, the rod 10 comprises a shank 8 which is longitudinally delimited by the end section 11 and has a substantially squashed rectangular section with rounded edges and symmetrical relative to a longitudinal median plane N shown in FIG. 1. The shank 8 has a reduced thickness relative to the extension of rod 10, so that it is flexible relative to the same plane N.

[0035] In FIG. 3, the end section 11 has a pointed shape and develops based on an isosceles triangular shape with a rounded tip that lies on the plane N. In particular, the section 11 is longitudinally developed between a bottom portion 14 and a rounded end 12. Moreover, the end section 11 is of a tapered type, therefore substantially arrow-shaped, and develops between the end 12 and the bottom portion 14. The end section 11 comprises a first face 110 that has a wedge-shaped cuspate lug 1100, which rises from the plane N. In addition, the end section 11 comprises a second face 112 which develops on the opposite side to the first face 110 relative to the plane N between the end 12 and the bottom portion 14. This second face 112 has a first projection 1120′ and a second projection 1120′ arranged between the end 12 and the bottom portion 14. In particular, it is useful to specify that the plane N separates the first face 110 from the second face 112.

[0036] In addition, with particular reference to FIGS. 3 and 4, the shank 8 is delimited by a third face 80 and by a fourth face 82 opposite to one another, each being recognisable to the touch by a respective first element 800 and second element 820 in differently shaped lug so as to be easily distinguishable. In particular, the first element 800 is profiled to schematically reproduce the shape of the lug 1100 in lateral elevation and the second element 820 is profiled to schematically reproduce the shape of the two projections 1120 and 1120′ in lateral elevation. The shank 8 also has a coupling portion 804 on the opposite side to the end 12, where this coupling element 804 is arranged for bayonet fitting with a handle H in a fixed and selectively releasable manner.

[0037] With particular reference to FIGS. 6-8, the lug 1100 is symmetrical relative to a longitudinal median plane M perpendicular to the plane N; the lug 1100 has a cusp 1101 shaped similarly to a pyramid with a base 1102 shaped similarly to an acute isosceles triangle having a vertex with a rounded base, as can be seen in FIG. 3, where this base is represented with a dotted line.

[0038] The cusp 1101 longitudinally divides the lug 1100 into a first portion 11110 placed on the side of the bottom portion 14 and a second portion 11112 placed on the side of the end 12, where the second portion 11112 has a longitudinal extension between 2 and three times the longitudinal extension of the first portion 11110 of the base.

[0039] Furthermore, with reference to FIGS. 9-15, the lug 1100 has a transverse section, according to planes perpendicular to both the planes N and M, shaped similarly to a Gaussian curve with rounded edges, wherein each of the FIGS. 10-15 shows, at the front, the shape of the corresponding section X-XV.

[0040] On the other hand, considering the second face 112 (see FIGS. 4 and 6-8) the respective first projection 1120 has a substantially trapezoidal plan with rounded vertices and the second projection 1120′ has a quadrilateral plan with rounded vertices symmetrical relative to the second plane M, where the part facing the end 12 is at least partially concave on that side. Both projections are represented in FIG. 4 with dotted lines. The first and second projections 1120 and 1120′ are symmetrically shaped relative to the median plane M and are connected by a substantially circular arcuate transverse section 1120″ (see the trace in FIG. 4).

[0041] It is deemed useful to specify that in FIG. 4 the plan of the second projection 1120′ may have a perimeter composed of any number of rounded sides and vertices without departing from the scope of the present invention according to different design requirements.

[0042] With particular reference to FIGS. 16a and 16b, the device 1 comprises a remover body 20, better seen in FIG. 16. This remover body 20 has a constant thickness (FIG. 16a), is shaped like an hourglass and, for this reason, it is provided with two flaps 22 connected end to end, each of which is shaped in plan with a shape that recalls an isosceles trapezium. Each flap 22 has a longitudinal extension equal to at least the longitudinal extension of the end section 11.

[0043] The remover body 20 is produced in polyether- or polyester-based reticulated polyurethane foam, it therefore has a plurality of cells similarly to what is described in the Italian patent IT 102016000088564. In particular, the cells are connected to one another through their respective linear edge elements to define a trabecular structure. For example, but in a non-limiting manner, the remover body 20 can be produced by using a material called Filtren® (a registered trademark of Eurofoam) which is intrinsically non-toxic and abrasive to the touch, therefore it is ideal for removing dental deposits. Its limited cost makes it particularly suitable for “disposable” uses, for which the device 1 was designed.

[0044] It should be pointed out that the hourglass shape of the remover body and the extension of the two flaps 22 allows the first face 110 and the second face 112 of the end section 11 to be completely covered with the remover body and in a conjugated manner. In particular, one of the hourglass-shaped faces of the remover body 20 (which joins the two flaps 22) is adhesive and has the purpose of permanently applying one of the two flaps 22 to the first face 110, adhering to the respective lug 1100, and the other flap to the second face 112 adhering to the first and second projections 1120 and 1120′, as can be seen in FIG. 16a.

[0045] The use of the device 1 is easily understandable from what has been described above and does not require further explanation. In particular, it may be useful to specify that the end section 11 has two faces shaped differently which makes the device 1 bivalent, therefore provided with two dental instruments with a practically identical longitudinal extension, one for the first face 110 and one for the second face 112 of the end section 11, usable for complementary purposes due to the different shapes of these faces. The fact that the device 1 has a substantially arrow-shaped tapered tip, with an increasing transverse section from the end 12 to the bottom portion 14, where the first face 110 and the second face 112 are abrasive due to the presence of the remover body 20 which facilitates the operation of the two dental instruments. With reference to the choice of conforming the shank 8 of the rod 10 having a squashed section as already described, it gives transversal elasticity to the shank 8 itself relative to the plane N, allowing a maximum force to be exerted on teeth and gums at the end section 11 which is correlated to the force sufficient to cause the bending of the shank 8.

[0046] In regard to what has been described above, the device 1 can be used to treat the lateral portions of the teeth, specifically those in which the molars are found, which delimit a slightly concave surface towards the outside with their external portion. This area, also known as the vestibular area, can be effectively treated by using the device 1 with the first face 110 provided with the cuspidate lug 1100 facing the molars and premolars. In particular, the device 1 can be used on the frontal portion of the teeth, which has incisors at the centre and canines at the sides, where this portion is convex and substantially arcuate-shaped, therefore particularly suitable to be treated by using the second face 112 due to the presence of the two projections 1120 and 1120′ connected by the arcuate section 1120″.

[0047] In addition, it should be specified that, the arrow-shape of the end section 11 makes it easy to reach the back of the mouth, in the concave vestibular space between the masseter, which is notoriously a particularly powerful and bulky muscle, which is why this space is considered particularly small and therefore normally unreachable with the devices discussed above without producing abnormal muscle tension and excessive pressure on the teeth. Therefore, the reduced dimensions of the end section 11 covered with the remover member 20 applied to the first face 110 and to the second face 112 make it particularly practical to clean all the areas of the mouth, including the internal surfaces of the cheeks, thus allowing the treated animal to keep its mouth almost completely closed, this being a condition of maximum muscle laxity, without causing trauma to the treated animal.

[0048] Finally, it is clear that modifications can be made to the device 1 described above without departing from the scope of the present invention.

[0049] It is easy to understand that, in the above description, no mention was ever made to the dimensions to be given to the device 1 and its constructive elements. This is because the dimensions and proportions of its own parts can be defined on the basis of the type of animal to be treated, possibly producing the device 1 with only one between the first face 110 and the second face 112 and with a rod 10 having a length and thickness definable according to the needs, in order to achieve the purposes illustrated above.

[0050] For example, but not limited to, if it is desired to externally sanitise the incisors of the upper and lower arches of horses, it will be convenient to adjust the size of the device 1 to the size of the teeth of these animals and to reinforce the rod 10 to allow the application of a greater tangential force to the teeth through the remover body 20 applied externally to the end section 11.

[0051] Considering that the incisors of these animals with closed jaws reproduce a multi-faceted surface with double curvature, in order to maximize the effectiveness of the operation it is preferable to brush this surface with the portion of the remover body 20 covering the second face 112 of the device 1.

[0052] In addition, in order to maximise the ability to remove food residues and calcium deposits from hard and/or soft surfaces of the mouth of animals, it may be useful to package the device 1 together with a toothpaste that would be used to cover the flaps 22 of the remover body 20 before starting the cleaning operation in contact with the teeth of the animal to be treated. The set of these items, the device 1 and the toothpaste, paste or powder, allows to package a kit that contains all the necessary and sufficient instrumentation to easily sanitize the teeth of an animal.

[0053] In regard to what is described above, the ease with which the device 1 makes it possible to reach every area of the dog's mouth is not possible through any device known in the prior art. For this reason, the device 1 is a very valid instrument to remove dental deposits with great effectiveness in animals, or even humans, with a limited cost and total safety for the operator who performs the sanitising treatment.
