The field of the invention is that of identifying and marking animals.
More precisely, the invention relates to a marking device, or tag, for identifying and marking farm animals, making it possible to treat animals. The invention in particular proposes an ear tag making it possible to avoid infections during the application of the tag and of the cicatrisation of the ear of the animal.
The identification of livestock was rendered mandatory in many countries in order to provide for the monitoring of the heard and guarantee the origin of the animals intended in particular for consumption. This marking concerns bovine as well as ovine, porcine or goats.
Conventionally, a tag includes an identification number inscribed on a label allowing the animal to be monitored all throughout its existence. For example, in accordance with European Directive 1760/2000, all bovine must be identified by an ear tag affixed to each ear, with both tags bearing the same unique identification code which makes it possible to identify each animal individually, as well as the farm where it was born. These tags must therefore be tamper proof in order to provide for the traceability of the animal, i.e. it must not be possible to remove a tag affixed to a first animal in order to re-install it on a second animal.
Ear tags made of plastic are the most commonly used. They include a loop bearing a label whereon is mentioned all of the legal data by printing or engraving, by laser marking, or any other means known to those skilled in the art. They are designed to be installed irreversibly, using a system of tamper proof fastening, associating in a snap locking arrangement a male component passing through the ear of the animal and a female component.
In addition to the constraints of inviolability, it is desirable to use tags that favour cicatrisation and avoid the infections on the wound formed in the ear of the animal, in particular to reduce the risks of suffering of the animals. Indeed, the opening made in the ear represents a source of infection wherein microorganisms, present for example on the farm where the animal is located, can develop and penetrate into the organism of the animal.
As such, EP 0 212 885 filed in the name of Sterimatic Holdings Limited has proposed to add a reservoir including a substance, for example a sterilising substance, to the female component of the tag.
According to this approach, a specific applicator is used comprising two jaws, one of them bearing a punch making it possible to pierce the ear of the animal.
More precisely, during the application of the tag, the punch is introduced into the male component, in order to first pierce the ear of the animal, then the membrane seal of the reservoir located in the female component, thus making it possible to release the sterilising substance.
This approach therefore requires the use of a male component comprising a hollow pin, wherein the punch is introduced.
Unfortunately, this technique is not very effective. Indeed, the male component is introduced into the female component practically at the same time that the punch penetrates the membrane seal. Consequently, the sterilising substance is at least partially blocked into the female component, and cannot reach the wound in order to disinfect it effectively.
Another disadvantage of this technique is that a reservoir (increasing the size of the tag and making its production and is implementation more complex) and a membrane seal closing this reservoir must be provided.
Furthermore, this membrane seal, even pierced by the punch, hinders an effective and complete distribution of the substance.
There is therefore a need for a new technique making it possible to avoid infections on the wound formed during the application of the tag, or at the very least to improve the implementation and the effectiveness of the corresponding treatment, in relation to the known techniques.
The invention proposes a new solution which does not have all of these disadvantages of prior art, in the form of a marking device for identifying and marking an animal, associating in a snap locking arrangement:
According to the invention, the pin is surrounded at least partially with a foam impregnated with a specific substance, so that the foam is compressed upon the engagement of said male and female components.
In other terms, the pin is surrounded at least partially with a foam that is able to be compressed between the skin of the animal to be marked and the base, and is able to release a specific substance in contact with the wound formed by the pin, upon the engagement of the male and female components.
As such, the invention proposes a new tag comprising, on its male component, a foam impregnated with a specific substance prior to the application of the tag.
The use of an impregnated foam on the male component of the marking device, makes it possible to ensure, upon the application of the tag, the application of the substance directly on the skin of the animal. Indeed, when the pin of the male component passes through the skin of the animal (conventionally the ear) to then become housed in the female component, the foam is squashed between the base and the skin of the animal, and releases the specific substance.
The substance is as such applied directly on the wound created by the pin, or a tip at the end of the pin, and in the vicinity of the latter, limiting the losses of substance.
In addition, the marking device according to the invention remains compatible with the conventional applicators, such as the “Total Tagger” (registered trademark) applicator, which allows the tag with or without foam to be installed.
It can be noted that the foam can fully surround the pin or surround it only partially, by means of one or several portions of foam. The quantity of foam and of substance on the male component can as such be limited and optimised.
In particular, the specific substance can be an antiseptic substance, making it possible to destroy at least partially the microorganisms (bacteria, viruses, etc.) that can cause infections on the opening made upon the application of the tag. This substance can in particular have the form of a gel, a cream, or a liquid impregnating the foam.
It can also entail a medication or a vaccine making it possible to care for or treat the animal (or a combination of these products), this substance being able to pass into the blood on the wound or to be absorbed by the skin of the animal.
As such, by reducing the risks of infection and the forming of abscesses, at the same time the risks of suffering are reduced for the animals and the state of health in the farm is improved. Adapted care can furthermore be administered, in case of need.
According to a particular characteristic of the invention, a lower face of the foam is fastened to the base, for example by gluing. It is as such possible to manufacture male components bearing such a foam. If it is desired to reduce the thickness of the foam used, it is also possible to add a buffer element between the base and the foam, and to fasten the foam to the base by the intermediary of the buffer element.
According to a first embodiment, the foam fully surrounds the pin, over a thickness less than or equal to the length of the pin.
In this case, the foam can be of a substantially cylindrical form, with the pin forming the axis of the cylinder, and may have one or several hollows on its upper face, i.e. on its face opposite the base.
The contact between the foam and the skin of the animal is as such reduced, which makes it possible to improve the distribution of the specific substance. The squashing of the foam and the release of the substance can as such be optimised. In addition, this structure makes it possible to optimise the circulation of air around the wound, which as such favours the cicatrisation thereof.
For example, these hollows form concentric crowns, around the pin.
According to a second embodiment, the foam covers the end of the pin opposite the base.
For example, the foam forms a tube surrounding the pin, and closed on the end of the pin. As such, the end of the pin, terminating with a tip for example, is protected from the outside environment before the application of the tag.
Upon application, the tip pierce the foam, then the skin of the animal, for example its ear, before becoming housed, irreversibly, in the cavity of the female component. The foam located along the pin is also compressed upon the application, releasing the specific substance.
As such, when the specific substance is an antiseptic substance, the pin of the male component is sanitized before piercing the ear of the animal, which makes it possible to further reduce the risks of infection.
Other forms, for example substantially cone-shaped or truncated cone-shaped, are possible. Several portions of foam distributed on the base can also be provided.
According to a particular characteristic of the invention, the foam is protected by a protective film, before the application of the tag. Such a film makes it possible in particular to avoid the drying of the specific substance, prior to installing the tag on the animal.
In particular, the marking device can be an ear tag.
Such a tag can be affixed to each ear of the animal, at a well-defined place in the ear, in accordance with European Directive 1760/2000.
Another aspect of the invention also relates to the male component of a marking device for identifying and marking of an animal, such as described hereinabove, and associating in a snap locking arrangement:
According to the invention, the pin is surrounded at least partially with a foam impregnated with a specific substance, so that the foam is compressed upon the engagement of said male and female components.
Such a male component is in particular able to interact with a female component such as presented hereinabove. This male component can of course comprise the various characteristics relative to the marking device according to the invention.
Other characteristics and advantages of the invention shall appear more clearly when reading the following description if a particular embodiment, provided as a simple non-restricted example, and of the annexed drawings, wherein:
The general principle of the invention is based on the use of a foam, of the polyurethane type for example, impregnated with a specific substance, for example an antiseptic, before the tag is installed. Such a foam is placed on the male component of a marking device, such that upon the engagement of the male and female components of the tag, the foam is squashed between the skin of the animal to be marked and the base of the male component, thus spreading the specific substance on the skin of the animal, in contact with the wound formed upon the engagement of the male and female components.
Hereinbelow an ear tag shall be described, intended to be affixed on the ear of an animal, for example of the bovine, ovine, porcine or goat type. Other locations on the body of the animal can also be considered for a tag according to the invention.
Firstly, an example of a marking device with a general structure of a known type is presented, as shown in a simplified manner in
Concerning the female component 5, the reception button 6 has an orifice 7 and a cavity 8 for the introduction of the tip 4 of the pin 3. The base of the female component can rest on the other face of the ear.
Once the tag 1 is installed, the tip 4 is housed in the cavity 8, and is maintained therein by a retaining shoulder 9 creating the transition between the cavity 8 and the orifice 7. It is therefore no longer possible to remove the tag, or to modify it, without breaking it once it has been installed.
Such tags bear small marked plates or labels identifying the animal. In particular, the button can contain a small plate providing a marking surface for the identification of the animal.
These tags can also, where applicable, be provided with electronic means of identification, such as a transponder or analogous device, housed for example inside the button. These are normally manufactured from a plastic material, but can also be made of aluminium or of steel.
It can be noted that several alternatives of the structure of this marking device have been proposed. Of course, the invention is not limited to the structure described hereinabove, but also applies to these alternatives.
In relation with
According to this first embodiment, the pin 3 is fully surrounded with a foam 21 impregnated with a specific substance, over a thickness e1 less than or equal to the length of the pin. The foam thus has a cylindrical form, with the pin forming the axis of the cylinder.
For example, the foam is a cellular plastic material.
Preferentially, the thickness e1 of the foam is chosen to be sufficiently thick enough so that the foam is squashed between the base 10 and the ear upon the engagement of the male and female components.
For example, if a pin of 20 mm in length is considered, with the pin penetrating 6 to 8 mm in the cavity 8, and if an ear thickness of the animal of a magnitude of 5 mm is considered, then the foam 21 can have a thickness greater than 9 mm, in order to be effectively compressed upon the application of the tag.
More precisely, upon the application of the tag, the foam 21 is compressed between the base 10 and the ear 30, and therefore has a thickness e2, with e2<e1. The specific substance contained in the foam 21 being released when the foam is squashed, it enters directly into contact with the skin of the animal, and the opening made in the ear of the animal. Indeed, the pin 3 is used as a guide to guide the substance through the opening made in the ear 30 of the animal. As such, in the case where this substance is an antiseptic substance, this makes it possible to disinfect the wound formed by the application of the tag.
According to this alternative, the foam 21 has several hollows 42 on its upper face, i.e. on the face of the foam that will come into contact with the skin of the animal upon the application of the tag.
For example, these hollows form concentric crowns, centred on the pin 3. As such, the foam 21 is formed of concentric bumps 41 and hollows 42, making it possible in particular to reduce the contact of the foam 21 on the ear 30 of the animal. The quantity of foam and of substance needed are as such reduced, while still allowing for a better distribution of the specific substance. In addition, the presence of hollows can make it possible to improve the circulation of the air between the marking device and the ear of the animal, as such favouring the cicatrisation of the wound.
Upon the application of the tag, the foam 21 is compressed between the base 10 and the ear 30. The specific substance contained in the foam 21 is then released, in contact with the skin of the animal, on the bumps 41.
According to another alternative not shown, the foam is formed of several portions (or sections) partially surrounding the pin. Such a foam is for example used for animals with fragile ears.
Finally,
More precisely,
According to this second embodiment, the pin 3 is surrounded with a foam 21 impregnated with a specific substance, also covering the tip 4.
As such, as shown in
As already indicated, the specific substance can be an antiseptic substance. The foam 21 covering the tip 4 therefore allows the tip 4 to be sanitized, before the application of the tag.
More precisely, upon the application, the tip 4 pierces the foam 21, then the ear 30 of the animal, before becoming housed, irreversibly, in the cavity of the female component 5.
As shown in
Such a technique can also be used to inject a vaccine or a medication into an animal, by impregnating the foam with such a substance.
In order to avoid the evaporation or the drying of the substance impregnating the foam, a protective film can be provided on the male component.
According to an alternative, the pin is surrounded at least partially with a “dry” foam, i.e. which is not impregnated in advance with a specific substance. The user then impregnates the foam with the specific substance before installing the tag, for example by soaking the foam in an antiseptic substance.
