Description

1. Domaine de l'invention1. Field of the invention

Le domaine de l'invention est celui de la collecte d'informations relatives à des animaux.The field of the invention is that of collecting information relating to animals.

Plus précisément, l'invention concerne un dispositif et un système de fixation d'un capteur de température, destinés à être placés dans le conduit auditif d'un animal, permettant de relever la température d'un animal, ponctuellement ou tout au long de son existence.More specifically, the invention relates to a device and a system for fixing a temperature sensor, intended to be placed in the ear canal of an animal, to raise the temperature of an animal, punctually or throughout. his existence.

En particulier, un tel système peut être équipé de moyens visuels et/ou électroniques d'identification, permettant d'identifier l'animal qui le porte.In particular, such a system may be equipped with visual and / or electronic identification means, to identify the animal that carries it.

Un tel système est destiné à équiper tout type d'animal, de compagnie ou d'élevage, et notamment les animaux voués à la consommation.Such a system is intended to equip any type of animal, company or farm, including animals dedicated to consumption.

2. Art antérieur2. Prior Art

Afin d'améliorer le suivi d'un cheptel, améliorer la productivité, détecter une maladie, une période d'ovulation, ou un vêlement dès les premiers symptômes, et/ou suivre l'évolution d'une maladie, il est de plus en plus courant de procéder à différents relevés de température sur les animaux concernés.In order to improve the monitoring of a herd, improve productivity, detect a disease, an ovulation period, or a calf at the first symptoms, and / or follow the evolution of a disease, it is increasingly It is more common to carry out different temperature readings on the animals concerned.

Pour ce faire, il a notamment été proposé dans la demande de brevet US2011251514 (Fever Tags ®) d'associer une sonde de température à une étiquette destinée à être fixée sur l'oreille d'un animal.To do this, it has been proposed in particular in the patent application US2011251514 (Fever Tags ®) to associate a temperature probe with a label intended to be fixed on the ear of an animal.

Un tel système de relevés de température, illustré en figure 1, comprend donc une partie mâle 11 et une partie femelle 12 formant l'étiquette, et une sonde 13 permettant d'effectuer des relevés de température. La sonde 13 est reliée à la partie femelle 12 par l'intermédiaire d'un câble 14. La partie femelle 12 est en outre équipée d'un indicateur visuel 121, permettant d'alerter un éleveur en cas de température anormale de l'animal.Such a system of temperature readings, illustrated in figure 1 , therefore comprises a male portion 11 and a female portion 12 forming the label, and a probe 13 for performing temperature readings. The probe 13 is connected to the female part 12 by means of a cable 14. The female part 12 is furthermore equipped with a visual indicator 121, making it possible to alert a breeder in the event of abnormal temperature of the animal. .

La sonde 13, ainsi qu'une partie du câble 14, sont insérés dans le conduit auditif de l'animal. Le reste du système est extérieur au conduit auditif, et fixé de manière classique à l'oreille de l'animal, par insertion de la partie mâle 11 dans la partie femelle 12, au travers de l'oreille de l'animal.The probe 13 and a portion of the cable 14 are inserted into the auditory canal of the animal. The remainder of the system is external to the ear canal, and conventionally attached to the ear of the animal, by insertion of the male part 11 into the female part 12, through the ear of the animal.

Un inconvénient de ce système de l'art antérieur est qu'il est particulièrement encombrant. Il existe ainsi un risque que l'animal coince le câble 14 dans une branche ou une clôture, entraînant le retrait de la sonde 13, ou se frotte à un autre animal et détériore le système. De plus, un tel système s'avère gênant pour l'animal.A disadvantage of this system of the prior art is that it is particularly bulky. There is thus a risk that the animal wedges the cable 14 in a branch or a fence, causing the removal of the probe 13, or rubs against another animal and deteriorates the system. In addition, such a system is troublesome for the animal.

Un autre inconvénient de ce système de l'art antérieur est qu'il ne remplace pas les marques d'identification animale, devant obligatoirement être apposées sur au moins une oreille de l'animal selon la législation de nombreux pays, de façon à permettre la traçabilité et la certification de l'origine des animaux. Il est donc nécessaire de percer l'oreille de l'animal à deux reprises, une fois pour apposer la marque d'identification, une fois pour fixer le système de relevés de température, ce qui engendre une souffrance supplémentaire pour l'animal, et peut être interdit dans certains pays.Another disadvantage of this system of the prior art is that it does not replace animal identification marks, which must be affixed to at least one ear of the animal according to the legislation of many countries, so as to allow the traceability and certification of the origin of animals. It is therefore necessary to pierce the ear of the animal twice, once to affix the identification mark, once to fix the system of temperature readings, which causes additional suffering for the animal, and may be prohibited in some countries.

Il est également connu du document FR 2 233 971 un dispositif d'indication d'une augmentation de la température d'un animal, comprenant un ensemble électronique fixé à l'animal par le biais d'un harnais, présentant des inconvénients similaires.It is also known from the document FR 2,233,971 a device for indicating an increase in the temperature of an animal, comprising an electronic assembly attached to the animal by means of a harness, having similar disadvantages.

Il est par ailleurs connu du document KR 2014 0077992 un dispositif de communication de données, notamment de la température corporelle d'un animal, s'insérant dans le conduit auditif d'un animal. Un tel dispositif, en forme d'obus, comprend une portion formée de polyuréthane et définissant un logement.It is also known from the document KR 2014 0077992 a device for communicating data, in particular the body temperature of an animal, fitting into the auditory canal of an animal. Such a device, shaped like a shell, comprises a portion formed of polyurethane and defining a housing.

Il existe un besoin pour un nouveau système de relevés de température d'un animal, mais qui ne présente pas l'ensemble des inconvénients de l'art antérieur.There is a need for a new system of temperature readings of an animal, but which does not have all the disadvantages of the prior art.

3. Exposé de l'invention3. Presentation of the invention

L'invention propose une solution nouvelle sous la forme d'un dispositif de fixation d'au moins un capteur de température à un animal, destiné à être placé dans le conduit auditif d'un animal selon la revendication 1.The invention proposes a novel solution in the form of a device for fixing at least one temperature sensor to an animal, intended to be placed in the ear canal of an animal according to claim 1.

Ainsi, l'invention repose sur une approche nouvelle et inventive du relevé de température d'un animal par son placement intégral dans le conduit auditif de l'animal permettant, par exemple, un encombrement réduit, moins de gêne pour l'animal et une diminution du risque de dysfonctionnement dû à l'environnement extérieur (par exemple un autre animal du cheptel, un accrochage dans la végétation, dans une clôture, etc).Thus, the invention is based on a new and inventive approach to the temperature measurement of an animal by its integral placement in the auditory canal of the animal allowing, for example, a small footprint, less discomfort for the animal and a decrease in the risk of malfunction due to the external environment (eg another animal in the flock, hanging in vegetation, fencing, etc.).

On note qu'un tel dispositif peut être maintenu dans le conduit auditif grâce à la deuxième portion formant ressort. Cette deuxième portion peut prendre appui sur au moins deux zones distinctes du conduit auditif, afin de maintenir le dispositif en place. En variante, la première portion et la deuxième portion prennent chacune appui sur une zone distincte du conduit auditif. De cette façon, le logement défini dans la première portion se trouve en contact avec le conduit auditif, ce qui permet une prise de température plus performante.It is noted that such a device can be maintained in the auditory canal thanks to the second spring portion. This second portion can be supported on at least two separate areas of the ear canal, in order to keep the device in place. Alternatively, the first portion and the second portion each bear on a separate area of the ear canal. In this way, the housing defined in the first portion is in contact with the auditory canal, which allows a more efficient temperature measurement.

En particulier, les deux zones distinctes du conduit auditif sont diamétralement opposées, ce qui permet un meilleur maintien du dispositif dans le conduit auditif.In particular, the two distinct areas of the auditory canal are diametrically opposed, which allows a better maintenance of the device in the auditory canal.

De plus, la deuxième portion formant ressort permet de laisser un passage d'air dans le conduit auditif. Le dispositif selon l'invention n'altère donc pas les capacités auditives de l'animal.In addition, the second spring portion allows to leave a passage of air in the ear canal. The device according to the invention therefore does not alter the auditory capabilities of the animal.

Selon une caractéristique particulière de l'invention, la deuxième portion est configurée pour prendre au moins deux positions, une position de compression et une position de maintien. Dans la position de compression, la deuxième portion est déformée de façon à permettre l'insertion du dispositif dans le conduit auditif. Dans la position de maintien, la deuxième portion reprend sensiblement et/ou tend à se rapprocher de sa forme d'origine de façon à maintenir le dispositif solidaire du conduit auditif.According to a particular characteristic of the invention, the second portion is configured to take at least two positions, a compression position and a holding position. In the compression position, the second portion is deformed so as to allow inserting the device into the ear canal. In the holding position, the second portion substantially resumes and / or tends to approach its original shape so as to maintain the device integral with the auditory canal.

En particulier, le logement apte à recevoir au moins un capteur de température et des moyens de transmission d'au moins une valeur de température comprend un orifice d'entrée du capteur de température et au moins un orifice d'échappement d'air.In particular, the housing adapted to receive at least one temperature sensor and transmission means of at least one temperature value comprises an inlet of the temperature sensor and at least one air exhaust port.

Un tel orifice d'échappement d'air permet de faciliter l'insertion du capteur de température dans le logement.Such an air exhaust port makes it easier to insert the temperature sensor into the housing.

Selon une caractéristique particulière de l'invention, la première portion définit un logement sensiblement cylindrique, dont une hauteur coïncide avec une première zone d'appui du conduit auditif lorsque le dispositif est placé dans le conduit auditif.According to a particular characteristic of the invention, the first portion defines a substantially cylindrical housing, a height of which coincides with a first bearing zone of the auditory canal when the device is placed in the auditory canal.

L'invention définit ainsi une zone de contact rapprochée et maximisée entre le capteur de température et la paroi du conduit auditif de l'animal, permettant ainsi une prise de température performante.The invention thus defines a zone of close and maximized contact between the temperature sensor and the wall of the auditory canal of the animal, thus allowing a high-performance temperature measurement.

En particulier, l'orifice d'entrée du capteur de température est situé sur une première base du logement sensiblement cylindrique, et le ou les orifice(s) d'échappement d'air sont situés à proximité d'une deuxième base du logement sensiblement cylindrique.In particular, the inlet of the temperature sensor is located on a first base of the substantially cylindrical housing, and or the air exhaust orifice (s) are located near a second base of the housing substantially cylindrical.

Selon un premier exemple de dispositif de fixation ne faisant pas partie de l'invention, la deuxième portion formant ressort se présente sous la forme d'un fourreau enveloppant au moins partiellement la première portion.According to a first example of a fastening device not forming part of the invention, the second spring portion is in the form of a sheath at least partially enveloping the first portion.

En particulier, le fourreau et la première portion sont confondus sur une partie destinée à prendre appui sur la première zone du conduit auditif. De plus, le fourreau est flexible au niveau d'une partie destinée à prendre appui sur la deuxième zone du conduit auditif. Ceci permet notamment de faciliter le placement du dispositif dans le conduit auditif de l'animal.In particular, the sleeve and the first portion are merged on a portion intended to bear on the first zone of the auditory canal. In addition, the sleeve is flexible at a portion intended to bear on the second zone of the auditory canal. This allows in particular to facilitate the placement of the device in the auditory canal of the animal.

Selon une caractéristique particulière, le fourreau comprend au moins un orifice d'entrée d'air et un orifice de sortie d'air situés de part et autre de la partie destinée à prendre appui sur la deuxième zone du conduit auditif. De tels orifices permettent un passage d'air dans le conduit auditif, afin de ne pas altérer les capacités auditives de l'animal.According to a particular feature, the sheath comprises at least one air inlet orifice and an air outlet orifice located on either side of the part intended to bear on the second zone of the auditory canal. Such openings allow air passage in the ear canal, so as not to alter the auditory capabilities of the animal.

Selon une autre caractéristique particulière, le fourreau prend une forme ogivale. Sa première extrémité, selon le sens d'introduction du dispositif dans le canal auditif, présente donc une forme arrondie, facilitant l'insertion du dispositif dans le canal auditif de l'animal et évitant de le blesser.According to another particular characteristic, the sheath takes an ogival shape. Its first end, in the direction of introduction of the device in the auditory canal, thus has a rounded shape, facilitating the insertion of the device in the ear canal of the animal and avoiding injury.

En particulier, le fourreau présente un axe longitudinal sensiblement parallèle à un axe longitudinal du logement.In particular, the sheath has a longitudinal axis substantially parallel to a longitudinal axis of the housing.

Selon l'invention, la deuxième portion comprend au moins une lame ressort et la première portion est un élément hélicoïdal, relié à la ou aux lames ressort.According to the invention, the second portion comprises at least one spring blade and the first portion is a helical element connected to the blade or blades spring.

Par exemple, selon un mode de réalisation, la deuxième portion comprend une unique lame ressort. Dans ce cas, l'élément hélicoïdal formant la première portion peut prendre appui sur une première zone du conduit auditif, et la lame ressort formant la deuxième portion peut prendre appui sur une deuxième zone du conduit auditif.For example, according to one embodiment, the second portion comprises a single spring blade. In this case, the helical element forming the first portion may bear on a first zone of the auditory canal, and the spring blade forming the second portion may bear on a second zone of the auditory canal.

Selon un autre mode de réalisation, la deuxième portion comprend trois lames ressort, réparties à distances égales autour de l'élément hélicoïdal. Dans ce cas, chaque lame ressort peut prendre appui sur une zone distincte du conduit auditif, en répartissant de manière égale les différentes forces.According to another embodiment, the second portion comprises three spring blades, distributed at equal distances around the helical element. In this case, each leaf spring can bear on a separate area of the auditory canal, distributing equally the different forces.

Selon un autre exemple de dispositif de fixation ne faisant pas partie de l'invention, la deuxième portion formant ressort est une plaque souple reliée par un de ses côtés à la première portion.According to another example of fastening device not forming part of the invention, the second spring portion is a flexible plate connected by one of its sides to the first portion.

Selon cet exempte, dans la position de compression, la plaque souple peut être enroulée au moins partiellement autour de la première portion, afin de faciliter l'insertion du dispositif dans le conduit auditif.According to this example, in the compression position, the flexible plate may be wound at least partially around the first portion to facilitate insertion of the device into the ear canal.

Selon un autre exemple de dispositif de fixation ne faisant pas partie de l'invention, les première et deuxième portions comprennent un élément hélicoïdal, formé d'au moins une spire d'un premier diamètre, définissant le logement, et d'au moins une spire d'un deuxième diamètre, formant ressort, le deuxième diamètre étant supérieur au premier diamètre.According to another example of a fastening device not forming part of the invention, the first and second portions comprise a helical element, formed of at least one turn of a first diameter, defining the housing, and at least one turn of a second diameter, forming a spring, the second diameter being greater than the first diameter.

Selon un autre aspect de l'invention, le dispositif comprend également au moins un logement apte à recevoir des moyens électroniques d'identification de l'animal.According to another aspect of the invention, the device also comprises at least one housing adapted to receive electronic means for identifying the animal.

En particulier, les moyens électroniques d'identification, le capteur de température et les moyens de transmission d'au moins une valeur de température peuvent être placés dans le même logement, afin de réduire l'encombrement du dispositif.In particular, the electronic identification means, the temperature sensor and the transmission means of at least one temperature value can be placed in the same housing, in order to reduce the size of the device.

Dans ce cas, les moyens de transmission d'au moins une valeur de température peuvent également être utilisés pour transmettre un identifiant de l'animal.In this case, the means for transmitting at least one temperature value can also be used to transmit an identifier of the animal.

Selon une autre caractéristique particulière de l'invention, le dispositif comprend une surface de marquage d'un identifiant de l'animal. Par exemple, une telle surface de marquage est définie sur la plaque souple, sur le fourreau, ou sur la lame ressort du dispositif de fixation.According to another particular characteristic of the invention, the device comprises a marking surface of an identifier of the animal. For example, such a marking surface is defined on the flexible plate, on the sheath, or on the spring blade of the fixing device.

Cela permet de disposer d'un identifiant visuel de l'animal, permettant de vérifier son identité lors du retrait du dispositif par exemple.This allows to have a visual identifier of the animal, to verify its identity when removing the device for example.

Selon une caractéristique particulière, le dispositif comprend des moyens de retrait du dispositif.According to a particular characteristic, the device comprises withdrawal means of the device.

De tels moyens prennent par exemple la forme d'une ficelle accrochée à la première et/ou à la deuxième portion, d'une encoche, etc, accessible à la main ou à l'aide d'un outil spécifique, afin de récupérer en toute facilité le dispositif lorsque nécessaire.Such means take for example the form of a string attached to the first and / or second portion, a notch, etc., accessible by hand or with the aid of a specific tool, to recover in all ease the device when needed.

L'invention concerne également un système de fixation d'au moins un capteur de température à un animal, destiné à être placé dans le conduit auditif d'un animal, selon la revendication 9.The invention also relates to a system for fixing at least one temperature sensor to an animal, intended to be placed in the ear canal of an animal, according to claim 9.

En particulier, un système comprend un dispositif de fixation tel que précédemment décrit. Il pourra donc bien sûr comporter les différentes caractéristiques relatives au dispositif de fixation selon l'invention, qui peuvent être combinées ou prises isolément. Ainsi, les caractéristiques et avantages de ce système sont les mêmes que ceux du dispositif de fixation. Par conséquent, ils ne sont pas détaillés plus amplement.In particular, a system comprises a fixing device as previously described. It can therefore of course include the various characteristics relating to the fixing device according to the invention, which can be combined or taken separately. Thus, the features and advantages of this system are the same as those of the fastener. Therefore, they are not detailed further.

En particulier, le système comprend également des moyens électroniques d'identification de l'animal, insérés dans le logement ou dans un autre logement du dispositif de fixation.In particular, the system also comprises electronic identification means of the animal, inserted in the housing or in another housing of the fixing device.

Selon un mode de réalisation particulier, les moyens électroniques d'identification, le capteur de température et les moyens de transmission d'au moins une valeur de température sont préalablement insérés dans une capsule en verre, ou « glass tag », insérée dans le logement formé par la première portion du dispositif de fixation.According to a particular embodiment, the electronic identification means, the temperature sensor and the transmission means of at least one temperature value are previously inserted in a glass capsule, or "glass tag", inserted in the housing. formed by the first portion of the fastener.

Un tel système permet notamment de placer intégralement un capteur de température dans le conduit auditif d'un animal afin de diminuer l'encombrement, de ne pas gêner l'animal et/ou de diminuer le risque de dysfonctionnement dû à l'environnement extérieur.Such a system makes it possible in particular to place a temperature sensor integrally in the ear canal of an animal in order to reduce the bulk, not to disturb the animal and / or to reduce the risk of malfunction due to the external environment.

Ce système permet également de placer intégralement un capteur de température et des moyens électroniques d'identification dans le conduit auditif de l'animal, ce qui évite de percer l'oreille de l'animal à plusieurs reprises, comme proposé dans l'art antérieur.This system also makes it possible to fully place a temperature sensor and electronic identification means in the auditory canal of the animal, which avoids piercing the ear of the animal several times, as proposed in the prior art. .

5. Description de modes de réalisation de l'invention5. Description of embodiments of the invention 5.1 Principe général5.1 General principle

Le principe général de l'invention repose sur un dispositif de fixation d'au moins un capteur de température comprenant deux portions, dont une première portion définissant au moins un logement pour recevoir le ou les capteurs de température et des moyens de transmission des températures relevées, éventuellement destinée à prendre appui sur au moins une zone du conduit auditif, et une deuxième portion formant ressort, destinée à prendre appui sur au moins une zone du conduit auditif.The general principle of the invention is based on a device for fixing at least one temperature sensor comprising two portions, a first portion of which defines at least one housing for receiving the temperature sensor (s) and means for transmitting the measured temperatures. , possibly intended to bear on at least one area of the auditory canal, and a second spring portion, intended to bear on at least one area of the auditory canal.

De ce fait, un tel dispositif, ou plutôt le système de fixation comprenant un tel dispositif, au moins un capteur de température et des moyens de transmission des températures relevées, peut être inséré en intégralité dans le conduit auditif d'un animal. Un tel système peut être placé de façon permanente dans le conduit auditif, afin d'effectuer un ou plusieurs relevés de température et transmettre ces relevés à un lecteur, placé à l'extérieur de l'animal.As a result, such a device, or rather the fixing system comprising such a device, at least one temperature sensor and means for transmitting the measured temperatures, can be inserted completely into the auditory canal of an animal. Such a system can be permanently placed in the ear canal, to perform one or more temperature readings and transmit these readings to a reader, placed outside the animal.

Pour ce faire, la première portion du dispositif de fixation définit un logement apte à recevoir le ou les capteurs de température, des moyens de transmission des températures relevées, et éventuellement des moyens électroniques d'identification de l'animal.To do this, the first portion of the fixing device defines a housing adapted to receive the temperature sensor or sensors, means for transmitting the temperatures recorded, and possibly electronic means for identifying the animal.

Par exemple, comme illustré en figure 2, le ou les capteurs de température 21, les moyens de transmission 22 des températures relevées, et éventuellement les moyens électroniques d'identification 23 de l'animal, sont préalablement insérés dans une capsule en verre 20, encore appelée « glass tag ». La première portion définit alors un logement sensiblement cylindrique, apte à recevoir un tel « glass tag ».For example, as illustrated in figure 2 the temperature sensor (s) 21, the transmission means (22) for the temperatures recorded, and possibly the electronic identification means (23) for the animal, are previously inserted in a glass capsule 20, also called a "glass tag". The first portion then defines a substantially cylindrical housing, adapted to receive such a "glass tag".

En particulier, si le « glass tag » comprend des moyens électroniques d'identification de l'animal 23, comprenant par exemple une antenne connectée à un élément de stockage portant un identifiant de l'animal, l'antenne des moyens électroniques d'identification peut être confondue ou mutualisée avec l'antenne formant les moyens de transmission 22 des relevés de température. Dans ce cas, la première portion peut définir un unique logement permettant de recevoir le « glass tag » 20 comprenant le ou les capteurs de température 21, les moyens de transmission 22 des températures relevées, et les moyens électroniques d'identification 23 de l'animal.In particular, if the "glass tag" comprises electronic means for identifying the animal 23, comprising for example an antenna connected to a storage element bearing an identifier of the animal, the antenna of the electronic identification means can be confused or shared with the antenna forming the transmission means 22 temperature readings. In this case, the first portion may define a single housing for receiving the "glass tag" 20 comprising the temperature sensor (s) 21, the transmission means 22 for the temperatures recorded, and the electronic identification means 23 for the animal.

Selon un autre mode de réalisation, au moins un second logement est prévu pour recevoir les moyens électroniques d'identification. Dans ce cas, une antenne des moyens électroniques d'identification n'est pas nécessairement commune avec l'antenne formant les moyens de transmission 22 des relevés de température.According to another embodiment, at least a second housing is provided to receive the electronic identification means. In this case, an antenna of the electronic identification means is not necessarily common with the antenna forming the transmission means 22 of the temperature readings.

La deuxième portion du dispositif de fixation, quant à elle, forme ressort. Elle est donc apte à prendre au moins deux positions, dont :

  • une position de compression, dans laquelle cette deuxième portion est déformée afin de permettre l'insertion du dispositif dans le conduit auditif de l'animal ;
  • une position de maintien, dans laquelle la deuxième portion tend à reprendre sa forme d'origine de façon à maintenir le dispositif dans le conduit auditif.
The second portion of the fastening device, in turn, forms spring. It is therefore able to take at least two positions, including:
  • a compression position, in which this second portion is deformed to allow the insertion of the device into the auditory canal of the animal;
  • a holding position, in which the second portion tends to return to its original shape so as to maintain the device in the auditory canal.

On présente désormais, en relation avec les figures 3A à 7B, différents modes de réalisation d'un dispositif ou d'un système de fixation d'un capteur de température selon l'invention, destiné à être placé dans le conduit auditif d'un animal.We now present, in relation with the FIGS. 3A to 7B , various embodiments of a device or a system for fixing a temperature sensor according to the invention, intended to be placed in the ear canal of an animal.

5.2 Premier exemple de dispositif de fixation5.2 First example of a fastening device

Selon un premier exemple de dispositif de fixation, illustré en figures 3A et 3B, on considère un système de fixation 30 comprenant un « glass tag » 20 tel qu'illustré en figure 2 (ou plus généralement un capteur de température et des moyens de transmission d'au moins une valeur de température), et un dispositif de fixation d'un capteur de température. Un tel dispositif de fixation comprend une première portion 31 destinée à prendre appui sur une première zone du conduit auditif, définissant au moins un logement apte à recevoir le « glass tag », et une deuxième portion 32 formant ressort, destinée à prendre appui sur une deuxième zone du conduit auditif, les première et deuxième zones du conduit auditif étant sensiblement diamétralement opposées.According to a first example of a fixing device, illustrated in Figures 3A and 3B a fixing system 30 comprising a "glass tag" 20 as illustrated in FIG. figure 2 (Or more generally a temperature sensor and means for transmitting at least one temperature value), and a device for fixing a temperature sensor. Such a fixing device comprises a first portion 31 intended to bear on a first zone of the ear canal, defining at least one housing adapted to receive the "glass tag", and a second portion 32 forming a spring, intended to bear on a second area of the auditory canal, the first and second areas of the auditory canal being substantially diametrically opposed.

Selon ce premier exemple, la première portion 31 définit un logement sensiblement cylindrique 311 dont une hauteur coïncide avec la première zone du conduit auditif, lorsque le système 30 est placé à l'intérieur de celui-ci. Un orifice 3111 d'entrée du capteur de température, situé sur une première base du logement cylindrique 311, permet l'insertion du « glass tag » 20 dans ce logement 311. Afin de faciliter l'insertion du « glass tag » 20 dans le logement 311, il est également prévu un orifice 3112 d'échappement d'air à proximité d'une deuxième base du logement cylindrique 311.According to this first example, the first portion 31 defines a substantially cylindrical housing 311 whose height coincides with the first zone of the auditory canal, when the system 30 is placed inside thereof. An inlet orifice 3111 of the temperature sensor, located on a first base of the cylindrical housing 311, allows the insertion of the "glass tag" 20 in this housing 311. In order to facilitate the insertion of the "glass tag" 20 into the housing 311, there is also provided an air exhaust port 3112 near a second base of the cylindrical housing 311.

La deuxième portion 32 formant ressort se présente sous la forme d'un fourreau de forme ogivale, enveloppant au moins partiellement la première portion 31.The second spring portion 32 is in the form of an ogival-shaped sheath, at least partially enveloping the first portion 31.

Par exemple, un tel fourreau présente un axe longitudinal AA' sensiblement parallèle à un axe longitudinal BB' du logement 311. En particulier, le fourreau et la première portion sont confondus sur une partie 321 destinée à prendre appui sur la première zone du conduit auditif, au niveau de la hauteur du logement 311.For example, such a sleeve has a longitudinal axis AA 'substantially parallel to a longitudinal axis BB' of the housing 311. In particular, the sleeve and the first portion are merged on a portion 321 intended to bear on the first zone of the auditory canal , at the height of housing 311.

La première extrémité 322 du fourreau, selon le sens d'introduction du système dans le canal auditif, présente une forme arrondie, de façon à faciliter l'insertion du système 30 dans le conduit auditif de l'animal.The first end 322 of the sleeve, in the direction of introduction of the system into the auditory canal, has a rounded shape, so as to facilitate the insertion of the system 30 in the ear canal of the animal.

L'autre extrémité du fourreau présente un évidemment permettant notamment de limiter la quantité de matière utilisée pour la fabrication du dispositif de fixation, comprenant :

  • une section courbe 323 ;
  • une section inclinée 324 ;
  • une section 325 sensiblement perpendiculaire à l'axe longitudinal AA' du fourreau.
The other end of the sheath has a recess notably making it possible to limit the quantity of material used for the manufacture of the fixing device, comprising:
  • a curved section 323;
  • an inclined section 324;
  • a section 325 substantially perpendicular to the longitudinal axis AA 'of the sleeve.

Afin de former ressort, le fourreau présente une partie flexible 326 destinée à prendre appui sur la deuxième zone du conduit auditif. Une telle partie flexible 326 peut être comprimée lors de l'insertion du système 30 dans le conduit auditif de l'animal, puis relâchée pour chercher à reprendre sa forme d'origine afin de maintenir le système 30 dans le conduit auditif de l'animal.In order to form a spring, the sheath has a flexible portion 326 intended to bear on the second zone of the auditory canal. Such a flexible portion 326 may be compressed upon insertion of the system into the animal's ear canal, and then released to seek to return to its original shape to maintain the system in the animal's ear canal. .

Pour ce faire, le fourreau est par exemple réalisé en matière plastique souple, comme le polyuréthane. La première portion 31 peut également être en polyuréthane, afin de faciliter l'insertion à force du « glass tag » 20 dans le logement 311.To do this, the sheath is for example made of flexible plastic material, such as polyurethane. The first portion 31 may also be made of polyurethane, in order to facilitate the forced insertion of the "glass tag" into the housing 311.

De plus, le fourreau présente au moins un orifice d'entrée d'air 327 et au moins un orifice de sortie d'air 328 situés de part et d'autre de la partie flexible 326 destinée à prendre appui sur la deuxième zone du conduit auditif, afin de ne pas altérer les capacités auditives de l'animal, lorsque le système est placé dans le conduit auditif de l'animal.In addition, the sheath has at least one air inlet port 327 and at least one air outlet port 328 located on either side of the flexible portion 326 intended to bear on the second duct zone. auditory, so as not to alter the hearing ability of the animal, when the system is placed in the ear canal of the animal.

5.3 Premier mode de réalisation5.3 First embodiment

On présente maintenant, en relation avec les figures 4A et 4B, un premier mode de réalisation de l'invention.We now present, in relation to Figures 4A and 4B , a first embodiment of the invention.

On considère à nouveau un système de fixation 40 comprenant un « glass tag » 20 tel qu'illustré en figure 2 (ou plus généralement un capteur de température et des moyens de transmission d'au moins une valeur de température), et un dispositif de fixation d'un capteur de température.We consider again a fastening system 40 comprising a "glass tag" 20 as illustrated in FIG. figure 2 (Or more generally a temperature sensor and means for transmitting at least one temperature value), and a device for fixing a temperature sensor.

Un tel dispositif de fixation comprend une première portion 41 destinée à prendre appui sur une première zone du conduit auditif, définissant au moins un logement apte à recevoir le « glasstag » 20, et une deuxième portion 42 formant ressort destinée à prendre appui sur une deuxième zone du conduit auditif, les première et deuxième zones du conduit auditif étant sensiblement diamétralement opposées.Such a fixing device comprises a first portion 41 intended to bear on a first zone of the auditory canal, defining at least one housing adapted to receive the "glasstag" 20, and a second portion 42 forming a spring intended to bear on a second zone of the auditory canal, the first and second zones of the auditory canal being substantially diametrically opposed.

Selon ce premier mode de réalisation, la première portion 41 est un élément de forme hélicoïdale. Cet élément hélicoïdal définit un logement sensiblement cylindrique 411 dont une hauteur coïncide avec la première zone du conduit auditif, lorsque le système 40 est placé à l'intérieur de celui-ci. Un orifice 4111 d'entrée du capteur de température, situé sur une première base du logement sensiblement cylindrique 411, permet l'insertion du « glass tag » 20 dans ce logement 411. Afin de faciliter l'insertion du « glass tag » 20 dans le logement 411, il est également prévu une pluralité d'orifices 4112 d'échappement d'air à proximité d'une deuxième base du logement sensiblement cylindrique 411, permettant l'échappement de l'air lors de l'insertion du « glass tag » dans le logement 411.According to this first embodiment, the first portion 41 is a helically shaped element. This helical element defines a substantially cylindrical housing 411 whose height coincides with the first zone of the auditory canal, when the system 40 is placed inside thereof. A 4111 input port of the temperature sensor, located on a first base of the substantially cylindrical housing 411, allows the insertion of the "glass tag" 20 in this housing 411. To facilitate the insertion of the "glass tag" 20 in the housing 411, it is also provided a plurality of orifices 4112 d exhaust air near a second base of the substantially cylindrical housing 411, allowing the escape of air during the insertion of the "glass tag" in the housing 411.

La deuxième portion 42 formant ressort se présente sous la forme d'une lame ressort, reliée à l'élément hélicoïdal. Cette lame ressort permet une insertion aisée du système 40 dans le conduit auditif, lorsqu'elle se trouve dans sa position de compression et permet de maintenir le système 40 dans le conduit auditif lorsqu'elle tend à reprendre sa forme d'origine.The second portion 42 forming a spring is in the form of a spring blade, connected to the helical element. This leaf spring allows easy insertion of the system 40 in the ear canal, when in its compression position and keeps the system 40 in the ear canal when it tends to return to its original shape.

Par exemple, la lame ressort et l'élément hélicoïdal peuvent être formés d'un seul tenant, à partir d'une tige métallique ou plastique que l'on vient enrouler pour former la première portion 41, et courber pour former la deuxième portion 42.For example, the leaf spring and the helical element can be formed in one piece, from a metal or plastic rod that is wound to form the first portion 41, and bend to form the second portion 42 .

5.4 Deuxième mode de réalisation5.4 Second embodiment

On présente maintenant, en relation avec les figures 5A et 5B, un deuxième mode de réalisation de l'invention.We now present, in relation to Figures 5A and 5B , a second embodiment of the invention.

On considère à nouveau un système de fixation 50 comprenant un « glass tag » 20 tel qu'illustré en figure 2 (ou plus généralement un capteur de température et des moyens de transmission d'au moins une valeur de température), et un dispositif de fixation d'un capteur de température.Consider again a fastening system 50 comprising a "glass tag" 20 as illustrated in FIG. figure 2 (Or more generally a temperature sensor and means for transmitting at least one temperature value), and a device for fixing a temperature sensor.

Un tel dispositif de fixation comprend une première portion 51 définissant un logement apte à recevoir le « glass tag » 20, et une deuxième portion 52 destinée à prendre appui sur au moins deux zones du conduit auditif, par exemple trois zones, situées sensiblement à égales distances dans le conduit auditif.Such a fixing device comprises a first portion 51 defining a housing adapted to receive the "glass tag" 20, and a second portion 52 intended to bear on at least two areas of the auditory canal, for example three zones, located substantially equal. distances in the auditory canal.

Selon ce deuxième mode de réalisation, la première portion 51 est un élément de forme hélicoïdale, définissant un logement sensiblement cylindrique 511.According to this second embodiment, the first portion 51 is a helically shaped element, defining a substantially cylindrical housing 511.

Un orifice 5111 d'entrée du capteur de température, situé sur une première base du logement sensiblement cylindrique 511, permet l'insertion du « glass tag » 20 dans ce logement 511. Afin de faciliter l'insertion du « glass tag » 20 dans le logement 511, il est également prévu une pluralité d'orifices 5112 d'échappement d'air à proximité d'une deuxième base du logement sensiblement cylindrique 511, permettant l'échappement de l'air lors de l'insertion du « glass tag » dans le logement 511.An inlet 5111 of the temperature sensor inlet, located on a first base of the substantially cylindrical housing 511, allows the insertion of the "glass tag" 20 in this housing 511. In order to facilitate the insertion of the "glass tag" 20 into the housing 511, there is also provided a plurality of orifices 5112 exhaust air near a second base of the substantially cylindrical housing 511, allowing the escape of air during the insertion of the "glass tag In dwelling 511.

La deuxième portion 52 formant ressort se présente sous la forme d'une pluralité de lames ressort, par exemple trois lames, reliées à l'élément hélicoïdal. Ces lames ressort permettent une insertion aisée du système 50 dans le conduit auditif, lorsqu'elles se trouvent dans leur position de compression, et permettent de maintenir le système 50 dans le conduit auditif lorsqu'elles tendent à reprendre leur forme d'origine.The second portion 52 forming a spring is in the form of a plurality of spring blades, for example three blades, connected to the helical element. These spring blades allow easy insertion of the system 50 into the auditory canal, when they are located in their compression position, and keep the system 50 in the ear canal when they tend to return to their original shape.

Par exemple, l'élément hélicoïdal est formé de trois hélicoïdes. Une lame ressort et une hélicoïde peuvent alors être formées d'un seul tenant, à partir d'une tige métallique ou plastique que l'on vient enrouler pour former l'hélicoïde, et courber pour former la lame ressort. Les trois ensembles « lame ressort / hélicoïde » sont alors rassemblés pour fermer le logement 511.For example, the helical element is formed of three helicoids. A spring blade and a helicoid can then be formed in one piece, from a metal rod or plastic that is just wound to form the helicoid, and bend to form the leaf spring. The three sets "leaf spring / helicoid" are then assembled to close the housing 511.

5.5 Autre exemple de dispositif de fixation5.5 Another example of a fastening device

On présente maintenant, en relation avec les figures 6A et 6B, un autre exemple de dispositif de fixation. On considère à nouveau un système de fixation 60 comprenant un « glass tag » 20 tel qu'illustré en figure 2 (ou plus généralement un capteur de température et des moyens de transmission d'au moins une valeur de température), et un dispositif de fixation d'un capteur de température.We now present, in relation to Figures 6A and 6B another example of a fixing device. Consider again an attachment system 60 comprising a "glass tag" 20 as illustrated in FIG. figure 2 (Or more generally a temperature sensor and means for transmitting at least one temperature value), and a device for fixing a temperature sensor.

Un tel dispositif de fixation comprend une première portion 61 destinée à prendre appui sur une première zone du conduit auditif, définissant un logement apte à recevoir le « glass tag » 20, et une deuxième portion 62 destinée à prendre appui sur au moins une deuxième zone du conduit auditif.Such a fixing device comprises a first portion 61 intended to bear on a first zone of the auditory canal, defining a housing adapted to receive the "glass tag" 20, and a second portion 62 intended to bear on at least a second zone of the auditory canal.

Selon cet exemple, la première portion 61 définit un logement sensiblement cylindrique 611 dont une hauteur coïncide avec la première zone du conduit auditif, lorsque le système 60 est placé à l'intérieur de celui-ci. Un orifice 6111 d'entrée du capteur de température, situé sur une première base du logement cylindrique 611, permet l'insertion du « glass tag » 20 dans ce logement 611. Afin de faciliter l'insertion du « glass tag » 20 dans le logement 611, il est également prévu au moins un orifice 6112 d'échappement d'air à proximité d'une deuxième base du logement cylindrique 611, permettant l'échappement de l'air lors de l'insertion du « glass tag » 20 dans le logement 611.According to this example, the first portion 61 defines a substantially cylindrical housing 611 whose height coincides with the first zone of the auditory canal, when the system 60 is placed inside thereof. An inlet 6111 of the temperature sensor inlet, located on a first base of the cylindrical housing 611, allows the insertion of the "glass tag" 20 in this housing 611. In order to facilitate the insertion of the "glass tag" 20 into the 611 housing, it is also provided at least one air exhaust port 6112 near a second base of the cylindrical housing 611, allowing the escape of air during the insertion of the "glass tag" 20 in housing 611.

La deuxième portion 62 formant ressort comprend une plaque souple, par exemple de forme sensiblement rectangulaire, reliée par un de ses côtés 621 à la première portion 61.The second portion 62 forming a spring comprises a flexible plate, for example of substantially rectangular shape, connected by one of its sides 621 to the first portion 61.

Par exemple, une telle plaque est en plastique souple avec effet mémoire, ou est une lame métallique surmoulée de polyuréthane. La première portion 61 peut également être en polyuréthane, afin de faciliter l'insertion à force du « glass tag » 20 dans le logement 611.For example, such a plate is made of flexible plastic with memory effect, or is a metal blade overmolded with polyurethane. The first portion 61 may also be made of polyurethane, in order to facilitate the forced insertion of the "glass tag" into the housing 611.

Dans sa position de compression, la plaque souple est au moins partiellement enroulée autour de la première portion 61, facilitant l'insertion du système 60 dans le conduit auditif. Dans la position de maintien, la plaque souple est au moins partiellement déroulée. De cette façon, le dispositif de fixation peut prendre appui sur une première zone du conduit auditif au niveau de la première portion 61, et sur une deuxième zone du conduit auditif au niveau du côté 622 opposé au côté 621 relié à la première portion 61.In its compression position, the flexible plate is at least partially wound around the first portion 61, facilitating the insertion of the system 60 into the auditory canal. In the holding position, the flexible plate is at least partially unrolled. In this way, the fixation device can be supported on a first zone of the auditory canal at the level of the first portion 61, and on a second area of the ear canal at the side 622 opposite the side 621 connected to the first portion 61.

5.6 Autre exemple de dispositif de fixation5.6 Another example of a fastening device

On présente désormais, en relation avec les figures 7A et 7B, un autre exemple de dispositif de fixation. On considère à nouveau un système de fixation 70 comprenant un « glass tag » 20 tel qu'illustré en figure 2 (ou plus généralement un capteur de température et des moyens de transmission d'au moins une valeur de température), et un dispositif de fixation d'un capteur de température. Un tel dispositif de fixation comprend une première portion 71 définissant au moins un logement apte à recevoir le « glass tag » 20, et une deuxième portion 72 formant ressort, destinée à prendre appui sur au moins deux zones du conduit auditif, sensiblement diamétralement opposées.We now present, in relation with the Figures 7A and 7B another example of a fixing device. Consider again a fastening system 70 comprising a "glass tag" 20 as illustrated in FIG. figure 2 (Or more generally a temperature sensor and means for transmitting at least one temperature value), and a device for fixing a temperature sensor. Such a fixing device comprises a first portion 71 defining at least one housing adapted to receive the "glass tag" 20, and a second portion 72 forming a spring, intended to bear on at least two areas of the auditory canal, substantially diametrically opposed.

Selon cet exemple, les première portion 71 et deuxième portion 72 comprennent un élément hélicoïdal, formé d'au moins une spire d'un premier diamètre, définissant un logement sensiblement cylindrique 711, et d'au moins une spire d'un deuxième diamètre, formant ressort, le deuxième diamètre étant supérieur au premier diamètre.According to this example, the first portion 71 and second portion 72 comprise a helical element, formed of at least one turn of a first diameter, defining a substantially cylindrical housing 711, and at least one turn of a second diameter, forming a spring, the second diameter being greater than the first diameter.

Un orifice 7111 d'entrée du capteur de température, situé sur une première base du logement sensiblement cylindrique 711, permet l'insertion du « glass tag » 20 dans ce logement 711. Afin de faciliter l'insertion du « glass tag » 20 dans le logement 711, il est également prévu une pluralité d'orifices 7112 d'échappement d'air à proximité d'une deuxième base du logement sensiblement cylindrique 711.An inlet 7111 of the temperature sensor inlet, located on a first base of the substantially cylindrical housing 711, allows the insertion of the "glass tag" 20 into this housing 711. In order to facilitate the insertion of the "glass tag" 20 into the housing 711, there is also provided a plurality of orifices 7112 air exhaust near a second base of the substantially cylindrical housing 711.

La première portion 71 est formée d'au moins une spire d'un premier diamètre, reliée à la deuxième portion 72 formée d'au moins une spire d'un deuxième diamètre, supérieur au premier diamètre.The first portion 71 is formed of at least one turn of a first diameter, connected to the second portion 72 formed of at least one turn of a second diameter, greater than the first diameter.

Les spires de la deuxième portion 72 formant ressort peuvent être compressées selon le sens illustré par les flèches C, dans la position de compression, permettant une insertion aisée du système 70 dans le conduit auditif. Ces spires de la deuxième portion 72 permettent de maintenir le système 70 dans le conduit auditif lorsqu'elles tendent à reprendre leur forme d'origine.The turns of the second spring portion 72 may be compressed in the direction illustrated by the arrows C in the compression position, allowing easy insertion of the system 70 into the ear canal. These turns of the second portion 72 keep the system 70 in the ear canal when they tend to return to their original shape.

Par exemple, l'élément hélicoïdal formé des spires de premier diamètre et de deuxième diamètre peut être formé d'un seul tenant, à partir d'une tige métallique ou plastique que l'on vient enrouler selon le premier diamètre pour former la première portion 71, et enrouler selon le deuxième diamètre pour former la deuxième portion 72.For example, the helicoidal element formed of the turns of first diameter and second diameter may be formed in one piece, from a metal or plastic rod that is wound up according to the first diameter to form the first portion 71, and wind up to the second diameter to form the second portion 72.

5.7 Variantes5.7 Variants

Dans les modes de réalisation présentés ci-dessus, on a considéré que le ou les capteurs de température, les moyens de transmission d'au moins un relevé de température, et éventuellement les moyens électroniques d'identification, étaient insérés dans un « glass tag ». Bien entendu, il ne s'agit que d'un exemple de mise en oeuvre, et le ou les capteurs de température, les moyens de transmission d'au moins un relevé de température, et éventuellement les moyens électroniques d'identification peuvent prendre toute autre forme. On note que la forme du logement de la première portion du dispositif de fixation doit être adaptée à recevoir au moins le ou les capteurs de température et les moyens de transmission d'au moins un relevé de température.In the embodiments presented above, it has been considered that the temperature sensor or sensors, the means for transmitting at least one temperature reading, and possibly the electronic means of identification, were inserted in a "glass tag". Of course, this is only an example of implementation, and the temperature sensor or sensors, the means for transmitting at least one temperature reading, and possibly the electronic means of identification can take any other form. It is noted that the shape of the housing of the first portion of the fixing device must be adapted to receive at least one or more temperature sensors and the transmission means of at least one temperature reading.

De plus, le dispositif de fixation peut prévoir une surface de marquage, par exemple, sur la plaque souple, sur le fourreau, sur la lame ressort, sur les éléments hélicoïdaux, etc. Ainsi, des moyens visuels d'identification de l'animal peuvent également être ajoutés sur le dispositif de fixation, à la place ou en complément de moyens électroniques d'identification. De tels moyens visuels et/ou électroniques d'identification portent un identifiant de l'animal (numéro d'identification par exemple). Ce marquage peut être effectué par tout moyen connu (impression, gravure laser, jet d'encre, etc).In addition, the fixing device may provide a marking surface, for example, on the flexible plate, on the sheath, on the spring blade, on the helical elements, etc. Thus, visual means for identifying the animal may also be added to the fixing device, instead of or in addition to electronic identification means. Such visual and / or electronic identification means carry an identifier of the animal (identification number for example). This marking can be done by any known means (printing, laser engraving, inkjet, etc.).

Pour la mise en place du système de fixation, on peut utiliser un outil de type pince permettant de compresser la deuxième portion pour l'amener dans sa position de compression. Le dispositif de fixation du système de fixation peut également être placé en position de compression dans un injecteur, comme une seringue, et libéré dans le conduit auditif. La deuxième portion cherche alors à reprendre sa forme d'origine, ce qui permet de fixer de façon permanente le système dans le canal auditif. Le système de fixation peut également être inséré en force dans le conduit auditif.For the establishment of the fastening system, one can use a clamp type tool for compressing the second portion to bring it into its compression position. The fixation device of the fixation system can also be placed in the compression position in an injector, such as a syringe, and released into the ear canal. The second portion then seeks to return to its original form, which allows to permanently fix the system in the auditory canal. The fixation system can also be forcibly inserted into the ear canal.

On note à cet effet que la hauteur totale des systèmes de fixation 30, 40, 50, 60 et 70, avant la mise en place dans le conduit auditif, est au moins égale au diamètre du conduit auditif de l'animal concerné, afin d'assurer un maintien correct du système dans le conduit auditif et d'éviter une extraction involontaire. Les dimensions du dispositif de fixation sont adaptées aux dimensions du conduit auditif de l'animal concerné, et sont donc variables d'une catégorie d'animal à une autre. Par exemple, on considère que le diamètre du conduit auditif des bovins est de l'ordre de 8 mm. Le diamètre du dispositif de fixation, à l'état initial, peut être de l'ordre de 9 mm. Ainsi, dans la position de compression, la deuxième portion formant ressort doit être compressée pour diminuer le diamètre/la hauteur du dispositif de fixation à une dimension inférieure à 8 mm, et dans la position de maintien, la deuxième portion tend à reprendre sa forme d'origine, et se trouve bloquée par les parois du conduit auditif.It should be noted to this effect that the total height of the fixation systems 30, 40, 50, 60 and 70, before placement in the auditory canal, is at least equal to the diameter of the auditory canal of the animal concerned, so that ensure proper maintenance of the system in the ear canal and avoid unintentional extraction. The dimensions of the fixing device are adapted to the dimensions of the auditory canal of the animal concerned, and are therefore variable from one animal category to another. For example, it is considered that the diameter of the auditory canal of cattle is of the order of 8 mm. The diameter of the fixing device, in the initial state, may be of the order of 9 mm. Thus, in the compression position, the second spring portion must be compressed to reduce the diameter / height of the fastener to a dimension less than 8 mm, and in the holding position, the second portion tends to return to its shape. of origin, and is blocked by the walls of the auditory canal.

Par ailleurs, afin de faciliter le retrait du système du conduit auditif de l'animal, le dispositif de fixation peut être équipé de moyens de retrait, comme par exemple une ficelle, une encoche apte à coopérer avec un outil spécifique, etc.Furthermore, in order to facilitate removal of the system from the animal's auditory canal, the fixation device may be equipped with withdrawal means, such as for example a string, a notch adapted to cooperate with a specific tool, etc.
