La présente invention est relative à un dispositif portatif éloignant les moustiques et utilisation, notamment pour prévenir le paludisme et autres maladies transmises par les moustiques. The present invention relates to a portable device repelling mosquitoes and use, in particular for preventing malaria and other diseases transmitted by mosquitoes.
Dans les régions chaudes et humides, une espèce de moustique appelée l'anophèle transmet un protozoaire parasite du sang, le plasmodium falciparum. Ce protozoaire produit une maladie mortelle pour 1'homme : le paludisme. In hot, humid regions, a species of mosquito called anopheles transmits a parasitic blood protozoan, plasmodium falciparum. This protozoan produces a fatal disease for humans: malaria.
La lutte contre le paludisme s'effectue par l'utilisation de médicaments curatifs administrés aux personnes malades. Ces médicaments sont à base d'antipaludéens tels que la chloroquine, la quinine, la méfloquine ou l'halofantrine. The fight against malaria is carried out by the use of curative drugs administered to sick people. These drugs are based on antimalarials such as chloroquine, quinine, mefloquine or halofantrine.
La prévention présente de nombreux avantages par rapport au traitement en évitant à la population les inconvénients d'une maladie mortelle avec tous les risques que comporte un traitement peut-être appliqué trop tard. Un médicament à base de chloriquine a semblé idéal pour la prophylaxie par son efficacité et son faible coût de fabrication. Prevention has many advantages compared to treatment by avoiding the population the disadvantages of a fatal disease with all the risks that a treatment may be applied too late. A drug based on chloriquine seemed ideal for prophylaxis by its effectiveness and its low manufacturing cost.
Mais de nombreuses résistances sont apparues. Il en est de même pour les autres substances antipaludéennes comme par exemple la proguanil ou la méfloquine. Parfois l'association de deux de ces substances à été utilisée pour faire face à ces nouvelles résistances du paludisme. But many resistances appeared. It is the same for the other antimalarial substances such as for example proguanil or mefloquine. Sometimes the combination of two of these substances has been used to cope with these new resistances of malaria.
Suites aux limites qui apparaissent avec les substances prophylactiques et après constatation que les piqûres de moustiques transmettent d'autres maladies, comme c'est le cas pour la dengue dans les Antilles et les régions voisines, typiquement à Cuba et au Honduras, la prévention repose sur la lutte contre les moustiques et leurs piqûres. On connaît les moustiquaires, mais la protection contre les piqûres de moustiques est limitée au petit espace englobé à l'intérieur de ladite moustiquaire. Suite à des recherches génétiques longues et complexes des moustiques mâles traités génétiquement ont été lâchés par hélicoptère pour stériliser les Following the limits that appear with prophylactic substances and after finding that mosquito bites transmit other diseases, as is the case for dengue in the Antilles and neighboring regions, typically in Cuba and Honduras, prevention is based on the fight against mosquitoes and their bites. Mosquito nets are known, but protection against mosquito bites is limited to the small space enclosed inside said mosquito net. Following long and complex genetic research, genetically treated male mosquitoes were released by helicopter to sterilize

moustiques femelles responsables de la transmission du paludisme. Mais ces expériences n'ont pas obtenu le résultat escompté. De plus, les moustiques traités ne sont pas forcément ceux qui sont situés à proximité d'êtres humains. Cette prévention connue est en outre limitée géographiquement à un espace déterminé, même si celui-ci peut être vaste. female mosquitoes responsible for the transmission of malaria. However, these experiments did not obtain the expected result. In addition, the mosquitoes treated are not necessarily those which are close to human beings. This known prevention is also limited geographically to a specific space, even if it may be large.
La présente invention a notamment pour but de remédier à ces inconvénients. A cet effet, le dispositif éloignant les moustiques suivant l'invention est portatif, donc sans limites géographiques fixes. Ce dispositif comprend un moyen émettant des ultrasons à une fréquence comprise entre +/-20 000 et +/-40 000 Hz. Ledit moyen émetteur d'ultrasons est munie d'une pile et est fixé à un bracelet élastiquement déformable permettant le port du dispositif selon l'invention par un poignet humain. The object of the present invention is in particular to remedy these drawbacks. To this end, the mosquito repellent device according to the invention is portable, therefore without fixed geographical limits. This device comprises a means emitting ultrasound at a frequency between +/- 20,000 and +/- 40,000 Hz. Said means emitting ultrasound is provided with a battery and is attached to an elastically deformable bracelet allowing the wearing of the device according to the invention by a human wrist.
Grâce à cette émission d'ultrasons les moustiques s'éloignent car ne supportant pas lesdits ultrasons. Le dispositif étant fixé au poignet ne peut pas être oublié par l'utilisateur qui le porte sur lui en permanence. Thanks to this emission of ultrasound mosquitoes move away because they do not support said ultrasound. The device being attached to the wrist cannot be forgotten by the user who wears it permanently with him.
Suivant d'autres caractéristiques : - la pile du moyen émetteur d'ultrasons est rechargeable et reliée électriquement à une cellule photovoltaïque fixée au bracelet déformable, en vue de maintenir alimenté en permanence le moyen émetteur d'ultrasons en courant électrique, surtout dans les pays où l'alimentation électrique est disséminée et non généralisée ; - le moyen émetteur d'ultrasons comprend un transducteur et un oscillateur transmettant audit transducteur un balayage de fréquence variant de +/-20 000 à +/-40 000 Hz, de manière à maintenir les moustiques sensibles au dispositif selon l'invention malgré les variation du taux d'humidité de l'air ; - en vue de limiter l'encombrement du dispositif suivant l'invention, l'émetteur d'ultrasons est contenu dans un boîtier sur lequel est fixé la According to other characteristics: - the battery of the ultrasonic emitting means is rechargeable and electrically connected to a photovoltaic cell attached to the deformable bracelet, in order to keep the ultrasonic emitting means constantly supplied with electric current, especially in countries where the power supply is scattered and not generalized; the ultrasonic emitting means comprises a transducer and an oscillator transmitting to said transducer a frequency sweep varying from +/- 20,000 to +/- 40,000 Hz, so as to keep mosquitoes sensitive to the device according to the invention despite the variation in the humidity of the air; - in order to limit the size of the device according to the invention, the ultrasonic transmitter is contained in a housing on which the

L'invention a également pour objet l'utilisation d'un dispositif tel que décrit ci-dessus pour la prévention des maladies transmises par les moustiques, notamment le paludisme et la dengue. The invention also relates to the use of a device as described above for the prevention of diseases transmitted by mosquitoes, in particular malaria and dengue.
Un exemple non limitatif de mise en oeuvre de l'invention va maintenant être décrit en regard du dessin annexé sur lequel un dispositif conforme à l'invention servant à éloigner les moustiques pour prévenir le paludisme est représenté schématiquement. le dispositif représenté sur la Fig. comprend un boîtier 1 contenant un transducteur 2 émetteur d'ultrasons 3 relié à un oscillateur 4 et une pile rechargeable 5. La pile rechargeable 5 est reliée et alimentée en électricité d'origine solaire par une cellule photovoltaïque 6. Tous ces éléments, transducteur 2, oscillateur 4, pile rechargeable 5 et cellule photovoltaïque 6 sont contenu dans le boîtier 1. Ledit boîtier est fixé par deux extrémités à un bracelet ouvert 7. Ce bracelet ouvert 7 est élastiquement déformable et comprend un moyen de fermeture. Ledit bracelet 7 est d'une taille permettant par sa fermeture la fixation à un poignet humain. A nonlimiting example of implementation of the invention will now be described with reference to the appended drawing in which a device according to the invention used to repel mosquitoes to prevent malaria is shown diagrammatically. the device shown in FIG. includes a housing 1 containing a transducer 2 ultrasonic transmitter 3 connected to an oscillator 4 and a rechargeable battery 5. The rechargeable battery 5 is connected and supplied with electricity of solar origin by a photovoltaic cell 6. All these elements, transducer 2 , oscillator 4, rechargeable battery 5 and photovoltaic cell 6 are contained in the housing 1. The said housing is fixed by two ends to an open strap 7. This open strap 7 is elastically deformable and includes a closure means. Said bracelet 7 is of a size allowing, by its closure, attachment to a human wrist.
Le fonctionnement du dispositif selon l'invention est le suivant, une personne dans un pays chaud est humide a fixé le bracelet 7 à son poignet comme une montre. Par conséquent, elle reste à proximité du dispositif selon l'invention, aussi bien quand elle se déplace, que quand elle reste stationnaire au même endroit. La cellule photovoltaïque 6 transforme la lumière en courant électrique qui recharge la pile d'alimentation 5 du transducteur 2 émetteur d'ultrasons 3. Si bien que ce transducteur 2 reste alimenté et continue à émettre, même dans les régions
1 ne comprenant pas d'alimentation électrique. Dans les régions où l'alimentation électrique est abondante, si l'utilisateur du dispositif selon l'invention oublie de le recharger, la lumière rechargera ledit dispositif. The operation of the device according to the invention is as follows, a person in a hot country is humid has fixed the bracelet 7 on his wrist like a watch. Consequently, it remains close to the device according to the invention, both when it is moving and when it remains stationary in the same place. The photovoltaic cell 6 transforms the light into electric current which recharges the power supply battery 5 of the transducer 2 emitting ultrasound 3. So that this transducer 2 remains powered and continues to emit, even in the regions
1 not including electrical supply. In regions where the power supply is abundant, if the user of the device according to the invention forgets to recharge it, the light will recharge said device.
L'émission d'ultrasons par le dispositif selon l'invention chassera les moustiques qui ne supportent pas les ultrasons. L'évacuation des The emission of ultrasound by the device according to the invention will drive away mosquitoes which do not support ultrasound. Evacuation of

moustiques préviendra les maladies transmises par lesdits moustiques, paludisme, dengue, malaria, etc. en évitant les piqûres de moustiques (même non vecteurs de maladies). La sensibilité des moustiques aux ultrasons est variable selon l'humidité de l'air, mais reste comprise entre +/-20 000 Hz et +/-40 000 Hz. Un oscillateur 4 est relié au transducteur 2, de manière à ce que ce dernier émette en permanence les ultrasons 3 aux fréquences qui chassent les moustiques. mosquitoes will prevent diseases transmitted by said mosquitoes, malaria, dengue, malaria, etc. avoiding mosquito bites (even those that do not cause disease). The sensitivity of mosquitoes to ultrasound is variable according to the humidity of the air, but remains between +/- 20,000 Hz and +/- 40,000 Hz. An oscillator 4 is connected to the transducer 2, so that this the latter permanently emits ultrasound 3 at frequencies that repel mosquitoes.
Le dispositif selon l'invention se porte et se déplace de même manière qu'une montre en raison d'un encombrement comparable. The device according to the invention is worn and moves in the same way as a watch due to a comparable size.
Bien que l'invention ait été décrite en liaison avec des structures bien particulières, elle n'y est nullement limitée et on peut y apporter de nombreuses variantes, comme par exemple des combinaisons différentes des composants du dispositif telle que la fixation de la cellule photovoltaïque 6 sur le bracelet 7 ou la suppression d'un élément comme le boîtier 1, sans sortir du cadre de l'invention. Although the invention has been described in connection with very specific structures, it is in no way limited to it and many variations can be made to it, such as for example different combinations of the components of the device such as the fixing of the photovoltaic cell. 6 on the bracelet 7 or the removal of an element such as the case 1, without departing from the scope of the invention.
