Definitions

• the field of the invention is that of collecting information relating to animals.
• the invention relates to a device and a system for fixing a temperature sensor, intended to be placed in the auditory canal of an animal, for raising the temperature of an animal, punctually or throughout his existence.
• such a system may be equipped with visual and / or electronic identification means, to identify the animal that carries it.
• Such a system is intended to equip any type of animal, company or farm, including animals dedicated to consumption.
• Such a system of temperature readings thus comprises a male part 11 and a female part 12 forming the label, and a probe 13 making it possible to take 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. .
• 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.
• 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.
• 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.
• 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.
