Description

DISPOSITIF DE MESURE DE LA TEMPERATURE D'UN ANIMAL DEVICE FOR MEASURING THE TEMPERATURE OF AN ANIMAL
La présente invention concerne un dispositif de mesure de la température de la queue du corps d'un animal, notamment en vue de la détection de l'instant précédant l'accouchement des femelles bovines ou équines .The present invention relates to a device for measuring the temperature of the tail of the body of an animal, in particular for the detection of the instant before childbirth of bovine or equine females.
Il est établi que la température corporelle interne des femelles bovines qui arrivent au terme de leur gestation subit des modifications permettant de déterminer l'imminence de l'accouchement. En effet, jusqu'à 56 heures environ avant le vêlage, la température corporelle demeure relativement constante avec des écarts quotidiens relativement similaires d'un jour à l'autre. A l'approche du part, la température corporelle subit invariablement une élévation significative suivie plus ou moins brutalement d'une baisse importante avant de s'élever à nouveau dans les heures précédant le vêlage, comme on peut le voir sur la figure 6. C'est la raison pour laquelle l'interprétation de ces fluctuations de la température corporelle précédant le vêlage peut-être intéressante pour prédire le moment de l'accouchement et s'avérer utile pour déterminer le moment crucial à compter duquel une assistance obstétricale pourrait s'avérer indispensable afin de réduire la mortalité périnatale des veaux.It has been established that the internal body temperature of bovine females who are reaching the end of their gestation undergoes modifications which make it possible to determine the imminence of childbirth. Indeed, until approximately 56 hours before calving, the body temperature remains relatively constant with relatively similar daily variations from one day to the next. As the part approaches, the body temperature invariably undergoes a significant rise followed more or less suddenly by a significant drop before rising again in the hours before calving, as can be seen in Figure 6. C This is the reason why the interpretation of these fluctuations in body temperature preceding calving may be useful for predicting the time of delivery and being useful in determining the crucial moment from which obstetric assistance could be given. prove essential in order to reduce perinatal mortality of calves.
Cette particularité physiologique est mise à profit par les éleveurs. En effet, pour prévoir la mise-bas, ils relèvent à intervalles réguliers de 12 ou 24 heures la température rectale de leurs animaux à terme. Malheureusement, une telle façon de faire ne leur permet Pas de tirer pleinement profit de l'opportunité de ce phénomène naturel et de détecter avec précision l'évolution des fluctuations de la température rectale. De plus, cette méthode perturbe l'animal, ce qui peut avoir une incidence sur la valeur mesurée. D'autre part, elle est très astreignante pour l'éleveur qui doit passer beaucoup de temps derrière les femelles à surveiller, en maintenant le thermomètre en place dans le rectum au moins trente secondes.This physiological feature is taken advantage of by breeders. In fact, to plan for parturition, they raise the rectal temperature of their animals at regular intervals of 12 or 24 hours. Unfortunately, this approach allows them does P have to take full advantage of the opportunity of this natural phenomenon and accurately detect changes in rectal temperature fluctuations. In addition, this method disturbs the animal, which can affect the measured value. On the other hand, it is very demanding for the breeder who must spend a lot of time behind the females to be monitored, in particular keeping the thermometer in place in the rectum for at least thirty seconds.
De même, il est connu que la température corporelle des femelles équines qui arrivent au terme de leur gestation subit des modifications permettant de déterminer l'imminence de l'accouchement. En effet, jusqu'à 4 heures environ avant le poulinage, la température corporelle de la jument demeure relativement constante avec des écarts quotidiens relativement similaires d'un jour à l'autre. A l'approche du part, la température corporelle subit invariablement une baisse importante avant de s'élever à nouveau une heure après le poulinage, comme on peut le voir sur la figure 7. L'examen de l'Art antérieur nous apprend que des inventeurs ont proposés des applications permettant de réduire le délai nécessaire à la prise de température chez l'animal. Le brevet DE 3.610.960 décrit un appareil de surveillance de l'état de santé de l'animal qui permet de supprimer le délai d'attente nécessaire à l'équilibre thermique du capteur de température avant la prise de température afin de déterminer si l'animal est malade ou non. Il présente l'inconvénient de positionner un capteur de la température cutanée directement sur le pelage au niveau de l'encolure, de l'abdomen ou de la queue, qui présente un coefficient de résistance thermique variant suivant les régions du corps et selon les conditions climatiques, faussant les écarts absolus de température entre chaque mesure, ce qui rend impossible la détection d'une parturition.Similarly, it is known that the body temperature of equine females who reach the end of their gestation undergoes modifications making it possible to determine the imminence of childbirth. Indeed, until about 4 hours before foaling, the body temperature of the mare remains relatively constant with relatively similar daily differences from one day to another. When approaching the part, the body temperature invariably undergoes a significant drop before rising again one hour after foaling, as can be seen in FIG. 7. Examination of the prior art teaches us that inventors have proposed applications making it possible to reduce the time necessary for taking a temperature in animals. Patent DE 3,610,960 describes an animal health monitoring device which eliminates the waiting period necessary for the thermal equilibrium of the temperature sensor before taking the temperature in order to determine whether the animal is sick or not. It has the disadvantage of positioning a skin temperature sensor directly on the coat at the neck, abdomen or tail, which has a coefficient of thermal resistance varying according to the regions of the body and according to the conditions climatic conditions, distorting the absolute temperature differences between each measurement, which makes it impossible to detect parturition.
La présente invention où le but est de mesurer la température de la queue du corps d'un animal en continu vise à remédier à cet inconvénient en procurant un dispositif dont la sonde de température est logée et maintenue par la face interne d'un bracelet dans le sillon vertébral ventral de la queue où la peau naturellement glabre, c'est-à-dire dépourvue de poil présente une faible épaisseur, et située en regard d'un segment de l'artère et de la veine coccygiennes médianes. Le positionnement du capteur de température dans le sillon vertébral ventral et plus particulièrement au niveau des quatre premières vertèbres coccygiennes de la queue de l'animal permet de relever la température corporelle du bovin ou de l'équidé d'une manière permanente sans que ce relevé de température ne soit influencé par les conditions climatiques ; Ainsi, le dispositif de la présente invention permet-il, notamment, de détecter une variation significative de la température qui intervient avant l'accouchement des femelles bovines et équines . A cet effet ce dispositif de mesure de la température de la queue, du corps d'un animal, notamment en vue de la détection de l'instant précédant l'accouchement des femelles bovines, comprend un bracelet destiné à être serré autour de la base de la queue du corps dont la température doit être mesurée, ce bracelet portant les composants d'un thermomètre médical vétérinaire, à savoir un boîtier, contenant des circuits électroniques et un afficheur et/ou un module de communication, une sonde de température et un cordon conducteur de liaison reliant la sonde de température au boîtier du thermomètre remarquable en ce que la sonde de température est logée et maintenue en contact par la face interne du bracelet dans le sillon vertébral ventral de la queue . On décrira ci-après, à titre d'exemples non limitatifs, diverses formes d' exécution de la présente invention en référence aux dessins annexés sur lesquels : la figure 1 est une vue en élévation schématique d'un dispositif de mesure de la température suivant l'invention, appliqué autour de la base de la queue d'un animal.The present invention where the aim is to measure the temperature of the tail of the body of an animal continuously aims to remedy this drawback by providing a device whose temperature probe is housed and maintained by the internal face of a bracelet in the ventral vertebral furrow of the tail where the skin naturally glabrous, i.e. hairless is thin, and located opposite a segment of the median coccygeal artery and vein. The positioning of the temperature sensor in the ventral vertebral furrow and more particularly at the level of the first four coccygeal vertebrae of the tail of the animal makes it possible to raise the body temperature of the bovine or equine animal permanently without this reading temperature is influenced by climatic conditions; Thus, the device of the present invention makes it possible, in particular, to detect a significant variation in temperature which occurs before the birth of bovine and equine females. To this end, this device for measuring the temperature of the tail, of the body of an animal, in particular for the detection of the instant preceding the birth of bovine females, comprises a strap intended to be tightened around the base. of the tail of the body whose temperature is to be measured, this bracelet carrying the components of a veterinary medical thermometer, namely a case, containing electronic circuits and a display and / or a communication module, a temperature probe and a connecting conductive cord connecting the temperature probe to the housing of the thermometer, remarkable in that the temperature probe is housed and kept in contact by the internal face of the bracelet in the ventral vertebral groove of the tail. Various embodiments of the present invention will be described below, by way of non-limiting examples, with reference to the appended drawings in which: FIG. 1 is a diagrammatic elevation view of a device for measuring the following temperature the invention, applied around the base of the tail of an animal.

Les écarts de température sont déterminés en soustrayant, pour chaque heure de la journée, la moyenne horaire du jour de la moyenne des moyennes horaires homologues des trois jours précédents réalisées pour chaque heure de chacune de ces journées.- Figure 8 is a graph of the evolution of the differences in body temperature of a pubescent bovine female when approaching ovulation, presenting a peak characteristic of the temperature differences preceding the moment of ovulation as well as the small gap separating it from the hormonal peaks of LH (lutein hormone) and 17 beta-oes tradiol. The temperature differences are determined by subtracting, for each hour of the day, the hourly average of the day from the average of the homologous hourly averages of the three preceding days carried out for each hour of each of these days.
Sur les figures 1 et 2 est représenté un dispositif de mesure de température 1 suivant l'invention, appliqué autour de la queue 2 d'un animal femelle en fin de gestation, afin de permettre de détecter avec précision l'imminence de l'accouchement. Toutefois, une telle application n'est pas limitative et le dispositif de mesure 1 pourrait être employé, par exemple pour assurer un suivi clinique de la température des animaux notamment en vue de détecter le moment de l'apparition des chaleurs des femelles pubères comme on peut le voir sur la figure 8 ou pour révéler certaines maladies entraînant une élévation ou une diminution significative de la température corporelle.In FIGS. 1 and 2 is shown a temperature measurement device 1 according to the invention, applied around the tail 2 of a female animal at the end of gestation, in order to enable the imminent birth to be detected with precision. . However, such an application is not limiting and the measuring device 1 could be used, for example to ensure clinical monitoring of the temperature of the animals, in particular with a view to detecting the time of the onset of heat in pubescent females as can be seen in FIG. 8 or to reveal certain diseases leading to a significant increase or decrease in body temperature.
Le dispositif de mesure 1 comprend essentiellement un bracelet 3 serré autour de la queue 2, à faible distance de la base de l'attache de la queue au sacrum, et qui porte un thermomètre médical à usage vétérinaire. Ce thermomètre comprend un boîtier 4 fixé à l'extérieur du bracelet 3, une sonde de température 5 disposée à l'intérieur du bracelet 3 et appliqué par celui-ci contre la queue 2, et un cordon conducteur flexible et étanche 6 reliant la sonde 5 au boîtier 4. Sur les figures 1 et 2 la sonde de température 5 est représentée logée et maintenue en contact, par la partie inférieure du bracelet 3, avec la peau naturellement fine et glabre du sillon vertébral ventral de la queue 2, tandis que le boîtier 4 du thermomètre est situé sur la partie supérieure du bracelet 1 et de la queue 2, en étant ainsi aisément accessible. De ce fait, la sonde 5 et le boîtier 4 se trouvent dans des positions sensiblement opposées. Le bracelet 3 peut être de type fermé, en étant constitué par un anneau d'une seule bande élastique ou d'une bande non élastique avec une partie élastique, ou bien encore il peut être du type ouvert en étant formé d'une bande totalement non élastique pourvue, à ses deux extrémités, d'un dispositif de fermeture et de serrage progressif.The measuring device 1 essentially comprises a bracelet 3 tightened around the tail 2, a short distance from the base of the attachment of the tail to the sacrum, and which carries a medical thermometer for veterinary use. This thermometer comprises a housing 4 fixed to the outside of the bracelet 3, a temperature probe 5 disposed inside the bracelet 3 and applied by the latter against the tail 2, and a flexible and waterproof conductive cord 6 connecting the probe 5 to the housing 4. In FIGS. 1 and 2 the temperature probe 5 is shown housed and kept in contact, by the lower part of the bracelet 3, with the naturally fine and hairless skin of the ventral vertebral groove of the tail 2, while the thermometer box 4 is located on the upper part of the bracelet 1 and of the tail 2, thus being easily accessible. Therefore, the probe 5 and the housing 4 are in substantially opposite positions. Bracelet 3 can be of the closed type, consisting of a ring of a single elastic band or of a non-elastic band with an elastic part, or alternatively it can be of the open type, being formed of a completely non-elastic, provided at its two ends with a progressive closing and tightening device.
Dans la forme d'exécution non limitative représentée sur la figure 3, le bracelet 3 du type fermé, comprend une bande 3a_ en matière textile non élastique dont les deux extrémités sont reliées l'une à l'autre par une bande élastique 3b_ formant par exemple un soufflet, ce qui permet d'ajuster le bracelet 3 aux dimensions requises. Dans cette forme d'exécution, une lanière 7 portant, sur sa partie extrême, une bande d'une matière aut o-agrippante connue sous le nom de « VELCRO » 7a est cousue sur une partie extrême de la bande 3a_ du bracelet 3. La bande aut o-agrippante 7a de la lanière 7 est destinée à coopérer avec une bande aut o-agrippante complémentaire 3c_ du type « VELCRO » qui est cousue sur l'autre partie extrême de la bande non élastique 3a_. La lanière 7 enjambe le soufflet 3b_ pour consolider l'ensemble du bracelet 3 dans son diamètre utile.In the nonlimiting embodiment shown in FIG. 3, the bracelet 3 of the closed type, comprises a band 3a_ of non-elastic textile material, the two ends of which are connected to each other by an elastic band 3b_ forming by example a bellows, which makes it possible to adjust the bracelet 3 to the required dimensions. In this embodiment, a strap 7 carrying, on its part extreme, a strip of a self-gripping material known as “VELCRO” 7a is sewn onto an extreme part of the strip 3a_ of the strap 3. The self-gripping strip 7a of the strap 7 is intended to cooperate with a complementary self-gripping strip 3c_ of the "VELCRO" type which is sewn on the other extreme part of the non-elastic strip 3a_. The strap 7 spans the bellows 3b_ to consolidate the entire bracelet 3 in its useful diameter.
Dans la variante d'exécution représentée sur la figure 4, la bande 3a_ du bracelet 3, de type ouvert, est en totalité en matière élastique du type néoprène, par exemple et elle est pourvue, à ses deux extrémités de deux éléments, 3d_, 3e_ d'accrochage et de fermeture du bracelet 3. Ces éléments 3d_, 3e_ peuvent être des lanières d'une matière auto-agrippante telle que celle connue sous le nom de « VELCRO ».In the variant shown in FIG. 4, the band 3a_ of the bracelet 3, of the open type, is entirely made of elastic material of the neoprene type, for example and it is provided, at its two ends with two elements, 3d_, 3e_ for attaching and closing the bracelet 3. These 3d_ elements, 3e_ can be strips of a self-gripping material such as that known under the name of "VELCRO".
Le boîtier 4 du thermomètre est logé dans un étui 8 qui est fixé sur la face externe du bracelet 3, de préférence à l'opposé de la position occupée par la sonde de température 5. L'étui 8 muni d'une fenêtre supérieure 8a_ présente une ouverture latérale 8b_ pour l'introduction du boîtier 4 dans l'étui 8, ladite ouverture latérale 8b_ pouvant être fermée par un volet rabattable 9 qui présente dans sa partie centrale une fenêtre 10 transparente et dans sa partie extrême un élément d'accrochage 9a_ coopérant avec un élément d'accrochage complémentaire 8c_ de l'étui 8. L'étui 8 présente, sur l'un de ses côtés et sensiblement à mi- largeur du bracelet 3, une ouverture 12 qui est située en regard d'un trou 13 percé dans la bande du bracelet 3. L'ouverture 12 et le trou 13 permettent ainsi au cordon conducteur flexible 6 de s'étendre à partir de l'intérieur de l'étui 8 jusqu'à la face interne de la bande 3a_ du bracelet 3. Sur cette face interne le cordon conducteur 6 est logé à l'intérieur d'une gaine en textile 14 qui est cousue le long de cette face interne, sur la plus grande partie de la longueur du cordon conducteur 6. Comme on peut mieux le voir sur la figure 3, le cordon conducteur 6 sort de l'extrémité de la gaine 14 et est raccordé à la sonde 5 située dans la zone inférieure du bracelet 3.The thermometer box 4 is housed in a case 8 which is fixed to the external face of the bracelet 3, preferably opposite to the position occupied by the temperature probe 5. The case 8 provided with an upper window 8a_ has a side opening 8b_ for the introduction of the housing 4 into the case 8, said side opening 8b_ being able to be closed by a folding flap 9 which has in its central part a transparent window 10 and in its end part a hooking element 9a_ cooperating with a complementary hooking element 8c_ of the case 8. The case 8 has, on one of its sides and substantially at mid-width of the bracelet 3, an opening 12 which is located opposite a hole 13 drilled in the strap band 3. The opening 12 and the hole 13 thus allow the flexible conductive cord 6 to extend from the inside of the case 8 to the internal face of the strip 3a_ of the bracelet 3. On this internal face the c conductive ordon 6 is housed inside a textile sheath 14 which is sewn along this face internal, over most of the length of the conductive cord 6. As can best be seen in FIG. 3, the conductive cord 6 comes out of the end of the sheath 14 and is connected to the probe 5 located in the area lower strap 3.
Dans la variante d'exécution représentée sur la figure 5, la sonde de température 5, sensiblement hémisphérique, est en matière inoxydable, non- allergénique et isotherme dans l'épaisseur de laquelle est contenu un capteur 17 sensible à la chaleur relié par les fils de liaison électriques 16 à la partie terminale du cordon conducteur 6. Le capteur 17 occupe une position affleurante et centrale au niveau de la face convexe 5a de la sonde 5. Le raccord du cordon conducteur 6 à la sonde 5 est réalisé à mi-hauteur du bord circulaire de la sonde 5.In the variant shown in FIG. 5, the temperature probe 5, which is substantially hemispherical, is made of stainless, non-allergenic and isothermal material in the thickness of which is contained a sensor 17 sensitive to heat connected by the wires of electrical connection 16 to the end part of the conductive cord 6. The sensor 17 occupies a flush and central position at the convex face 5a of the probe 5. The connection of the conductive cord 6 to the probe 5 is carried out at mid-height the circular edge of the probe 5.
De préférence, la face convexe 5a de la sonde de température 5 est appuyée contre la face inférieure de la queue de l'animal par l'intermédiaire d'un film adhésif et isotherme 15 (figure 2) pour permettre une immobilisation de la sonde 5 dans le creux du sillon vertébral de la queue.Preferably, the convex face 5a of the temperature probe 5 is pressed against the underside of the tail of the animal by means of an adhesive and isothermal film 15 (FIG. 2) to allow immobilization of the probe 5 in the hollow of the vertebral furrow of the tail.
Le boîtier 4 du thermomètre comporte un circuit électronique traditionnel, un écran à cristaux liquides, un compartiment destiné au logement d'une pile ou d'une batterie rechargeable, un interrupteur de marche et arrêt et des boutons de commande de diverses fonctions.The thermometer housing 4 includes a traditional electronic circuit, a liquid crystal screen, a compartment for housing a rechargeable battery or battery, an on and off switch and buttons for controlling various functions.
Le thermomètre peut être utilisé comme un thermomètre numérique classique, c'est-à-dire qu'après avoir mis en place le dispositif de mesure 1 sur la queue de l'animal, l'éleveur met en marche le thermomètre en appuyant sur le bouton marche et arrêt . Le thermomètre une fois la mesure de température terminée, conserve cette mesure en mémoire pour l'afficher à nouveau lors d'une prochaine mise en marche du thermomètre par l'éleveur. Le thermomètre peut aussi comporter un complément d'équipement permettant une surveillance continue de la température corporelle avec affichage permanent ou non de sa valeur en temps réel. Ainsi complété, le thermomètre peut enregistrer une valeur de la température à des intervalles de temps réguliers et pré-définis. Les valeurs de la température ainsi enregistrées peuvent être alors utilisées à deux fins :The thermometer can be used like a conventional digital thermometer, that is to say that after having set up the measuring device 1 on the tail of the animal, the breeder starts the thermometer by pressing on the on and off button. The thermometer once the temperature measurement is finished, keep this measurement in memory to display it again the next time the thermometer is started by the breeder. The thermometer can also include additional equipment allowing continuous monitoring of body temperature with permanent display or not of its value in real time. Thus completed, the thermometer can record a temperature value at regular and pre-defined time intervals. The temperature values thus recorded can then be used for two purposes:
1°) pour produire un signal sonore, lumineux ou l'envoi d'un appel ou d'un message à un outil de télécommunication, lorsqu'un seuil de température est franchi à la hausse ou à la baisse ;1 °) to produce an audible, luminous signal or the sending of a call or a message to a telecommunication tool, when a temperature threshold is crossed upward or downward;
2°) pour être transférées, par exemple par commande infrarouge, ondes radio, ou tout autre moyen de transmission sans fil, à un micro-ordinateur distant afin d'être exploitées à diverses fins grâce à l'utilisation de logiciels adaptés.2) to be transferred, for example by infrared control, radio waves, or any other means of wireless transmission, to a remote microcomputer in order to be used for various purposes through the use of suitable software.
On pourrait également concevoir que l'utilisateur du dispositif de mesure de température puisse interroger à distance le thermomètre à l'aide d'un ordinateur afin d'en collecter les informations enregistrées. A cette fin, un ensemble de relais de transmission pourrait être utilisé afin de permettre un échange des informations. Le thermomètre comporterait alors, outre un afficheur à cristaux liquides, des circuits micro-électroniques (de type CMS), un module de communication, et un logiciel informatique spécifique à son exploitation qui serait compatible avec les principaux systèmes d' exploitation informatiques . Un éclairage du cadran de l'afficheur à cristaux liquides pourrait être automatiquement mis en marche pendant une durée pré-définie lors de chaque allumage et réglage du thermomètre. L'écran à cristaux liquides doit afficher au minimum la valeur de la température mesurée et éventuellement l'heure et le jour correspondant à chaque mesure enregistrée. It could also be conceived that the user of the temperature measurement device could interrogate the thermometer remotely using a computer in order to collect the recorded information. To this end, a set of transmission relays could be used to allow an exchange of information. The thermometer would then include, in addition to a liquid crystal display, micro-electronic circuits (CMS type), a communication module, and computer software specific to its operation which would be compatible with the main computer operating systems. An illumination of the dial of the liquid crystal display could be automatically turned on for a preset time each time the thermometer is turned on and adjusted. The liquid crystal display must at least display the value of the measured temperature and possibly the time and day corresponding to each recorded measurement.
