Description

  The field of the invention is that of animal identification and / or tagging.

  More specifically, the present invention relates to an animal identification system that can be used to attach visual and / or electronic identification tags to any animal species.

  In particular, the present invention relates to a male part of an animal identification tag, also called an animal identification tool, comprising a longitudinal through channel through which a tissue data collection member can pass.

  By taking a tissue sample in this way, cells / tissues with particular biological or biochemical properties are stored, for example for later identification of animals or detection of animal diseases. be able to.

  Improve livestock tracking in particular, increase productivity (eg, by eliminating diseased animals or searching for a single genetic feature) and / or consumer animals (eg, by detecting disease) Increasingly, it has become common practice to perform one or more operations to collect tissue samples from related animals to ensure their origin.

  A sample can be taken from the animal when applying an identification tag to identify the animal (eg, at birth). Other tissue samples can also be collected throughout the life of the animal, for example to detect disease, prove the animal's identity by comparing DNA sequences, or assess the animal's genetic value. Once collected, animal tissue samples can be stored and / or sent to a laboratory for analysis.

  When taking a sample at the same time as tagging, there is a well-known method using a male part having a channel extending through the ends used to pass the sampling member.

  According to this example, the male part comprises a shaft extending from the base and terminating at a frustoconical tip. The shaft (including the tip with the head cut off) is hollow and defines a longitudinal channel through which the sampling needle can be passed.

  The sampling needle that is tagged or fixed to the jaw of the tagging clamp by the mounting support can be retracted after tagging. The cutting edge of the sampling needle is substantially circular and protrudes from the tip of the male shaft to puncture the animal's skin when tagging.

  Therefore, when attaching the tag, the needle punctures the animal's skin, and then the tip of the shaft is introduced into the cavity of the female part to irreversibly join the male part and the female part.

  Once the tag is attached, the needle can be retracted by sliding it off the shaft, and the tissue sample that has been cut off by the cutting edge and remaining in the needle can be recovered.

  These prior art tags are preferably made of flexible plastic to minimize the possible discomfort that can occur to the animal during movement of the animal and to prevent injury to the animal. By using a deformable material, for example, tearing of the animal's ear that may occur when a tag attached to the animal's ear is caught on a fence or a branch is prevented.

  One drawback of these tags is that the desired flexibility for the tags causes problems when the tags are attached and / or when tissue samples are taken. Indeed, because of the deformable material used, the shaft may be deformed when tagging. More specifically, the shaft tends to be compressed when the frustoconical tip contacts the animal. In particular, the shaft is deformed by buckling and is bent. This makes it difficult for the shaft to penetrate the female part at the height of this bend, and the inability of the tag is no longer completely guaranteed. It can happen that the tip forming the tip of the shaft fails to penetrate the female part. This makes the tag unusable. In addition, bending may interfere with the healing of the animal's ears.

  This problem does not exist for tags that cannot collect tissue samples. In fact, with this type of tag, a thin rod, typically made of metal and securely attached to the tagging tool to be tagged, is inserted into the shaft of the tag's male part and the shaft is either rigid or Make it rigid.

  However, this method is not applicable to tags that have a hollow shaft (ie, a longitudinal through channel between the ends) and are designed to collect tissue samples.

  Therefore, there is a need for a new type of tissue sampling tag that can overcome this shaft deformation problem while minimizing discomfort that occurs to the animal during animal movement and preventing animal injury. .

  The present invention overcomes all these disadvantages of the prior art with a shaft or stem that extends from the base and terminates in a lock head designed to be inserted into the female part to securely attach the identification device to the animal. We propose a new solution in the form of male parts for animal identification tools that we do not have.

  According to the present invention, the shaft is penetrated by a channel in the longitudinal direction through which a sampling member for collecting an animal tissue sample can be passed, and the shaft can be rigid along the longitudinal axis. Means. Such stiffening means comprises at least one abutment element located in the middle of the shaft and the distal tip of the head (ie opposite the base of the head) and protruding into the channel, The plurality of abutment elements define a bearing area that can support at least one bearing element of the sampling member when animal tissue is collected.

  The present invention provides a new solution that can optimize the tagging work for the male parts of animal identification tags / animal identification tools used to sample and simultaneously tag or attach animal tissue samples To do.

  In particular, the present invention provides means for stiffening the shaft along its longitudinal axis without compromising its primary sampling function. Such stiffening means is configured to temporarily prevent deformation of the shaft along its longitudinal axis from the lock head to the shaft base when the tag is mounted. Such stiffening means comprise at least one abutment element which takes the form of, for example, a toe, a narrowed channel, etc.

  Thus, when tagged, the present invention allows the shaft to buckle due to bending or bulging around a sampling member designed to puncture animal skin (eg, ear skin and cartilage). It will prevent it from happening.

  Thus, since there is no obstruction of the air circulation due to the presence of these bends, the injuries of animals are healed more quickly. Also, the male part shaft can be fitted into the female part with a length sufficient to close accurately and ensure the reliability of the tag.

  According to one particular feature of the present invention, the body of the shaft is made of an at least partially deformable material (eg polyurethane).

  Thus, the shaft body between the shaft base and the lockhead base is stiffened only during tagging / tissue harvesting operations. At the end of these operations, the sampling member is removed from the male part shaft, thus restoring its flexibility.

  Conventionally, the lock head is preferably made of a material that cannot be deformed to prevent disengagement after insertion into the female part.

  Note that the base with the shaft extending substantially vertically can also be made of at least partially deformable material. In this way, the base of the shaft (which can be larger or smaller) can be deformed, and thus animal skin that may occur when the base is caught on a fence, branch, etc. (eg, its Prevent ear) lacerations.

  According to one particular embodiment, the channel comprises at least two parts having different sections, and the abutment element corresponds to a transition region between the parts comprising different compartments.

  Specifically, the portions of the channel with different compartments are cylindrical and concentric.

  Thus, the transition region defines a coronal surface region that can support at least one bearing element of the sampling element to stiffen the body of the male shaft.

  Specifically, the portion located in front of the transition region from the base of the male shaft toward the lock head comprises a circular cross section having a larger diameter than the portion located after the transition region.

  According to this particular embodiment, the thickness of the material forming the body of the shaft in the part having different sections can be substantially constant.

  Thus, the outer sheath of the male shaft follows the shape of the channel, and the male shaft comprises at least two portions with different compartments along its body.

  Thus, the thickness of the male shaft between the base from which the shaft extends and the base of the lockhead is substantially constant, thus limiting the amount of material used to make the shaft.

  Specifically, the distance between the head and the transition region is such that the material of the transition region forming the body of the shaft abuts the base of the female component when the male and female parts are fitted together. .

  The male shaft defines a blocking region between the base of the lock head and the transition region, thus blocking the retaining ring in the female component inlet hole.

  In this way, the system blocks the male part more effectively within the female part.

  As a variant, the thickness of the material forming the body of the shaft located in front of the transition region from the shaft base towards the lock head of the male part is Smaller than the thickness of the material to be formed,

  Thus, the body of the male shaft has a generally cylindrical shape / outer sheath.

  According to another particular embodiment, the lockhead comprises an insert having a hardness that is greater than the hardness of the material forming the body of the shaft.

  The insert is made of a non-deformable material so that the locking part does not come off after being inserted into the female part, improving the reliability of the tag.

  As already indicated, the receiving part of the shaft for the part and / or the base of the shaft can be made of a deformable material.

  Specifically, the insert is a truncated cone, and a portion of the bottom of the truncated cone defines a transition region.

  Such an insert has in particular a longitudinal channel through which a sampling member for collecting a sample of animal qualities can be passed from end to end.

  According to another unique feature, the insert comprises at least one recess.

  Thus, for example, a male part can be easily made by overmolding the shaft (if necessary, the base of the shaft) on the insert. The material used for the shaft, such as polyurethane, is poured into one or more recesses in the insert so that the insert is securely attached to the receiving portion of the shaft.

  In particular, the base from which the shaft extends comprises a marking surface that marks the animal identifier. In order to be visible, this marking surface is preferably provided on the outwardly facing surface, ie the surface facing away from the male shaft.

  For example, such a shaft base can take the form of a disk, or a generally rectangular marking surface of a large size for cattle or a small size for sheep according to features well known to those skilled in the art. An extension can also be provided. Thus, the shaft base can be sized differently depending on the type of animal to be tagged.

  The animal identifier may be a visual identifier in the form of, for example, an alphanumeric code, a barcode, a matrix, or an electronic identifier such as a transponder.

  The present invention relates to a sampling member that can be at least partially inserted into the longitudinal channel of the male shaft as described above.

  According to the invention, such a sampling member comprises at least one bearing area that is complementary to the abutment element of the male part.

  Specifically, the distance between the sampling element bearing element and the sampling distal tip is such that the sampling distal tip protrudes from the male shaft when the bearing element hits the abutment element. Determined.

  In other words, the distance between the bearing element of the sampling member and the sampling distal tip is slightly less than the distance between the abutment element of the male part and the distal tip of the lock head (about 2 mm). )large.

  Such a sampling member comprises a biopsy needle type sampling element, a thin rod terminating in the tip type, or any other element used to sample tissue. The distal tip for sampling corresponds to the cutting ridge of the needle, the tip of the tip and the like. Such sampling elements are therefore called “needles”.

  For example, the bearing element is a ring firmly attached to the needle of the sampling member.

  Such a member advantageously also includes a mounting support that allows the needle to be handled for sampling operations and allows the needle to be securely mounted to the tagging tool.

  Optionally, such a sampling member comprises a pusher element housed in the longitudinal channel of the needle that allows the tissue sample to be pushed out of the needle once the tissue sample has been collected.

  The bearing element according to the invention may be part of the mounting support part, one or more studs provided at the height of the needle or support part, the extra thickness of the needle, etc.

In another embodiment, the present invention relates to an animal identification system comprising an animal identification tool,
The animal identification tool includes the male part described above, a female part including a cavity designed to receive the male part's lock head, and the sample collection member described above.

  This system comprises various features relating to the male part of the identification tool according to the invention or the sampling member according to the invention. These features can be employed in combination or individually. Thus, the features and advantages of this system are the same as those of the male part and sampling member described above. Therefore, they will not be described in further detail.

  Other features and advantages of the present invention will become more apparent from the following description of specific embodiments, given by way of non-limiting example only and with reference to the accompanying drawings.

Fig. 5 shows a female part and a sampling member of an animal identification tool according to a third embodiment of the present invention. Fig. 5 shows a female part and a sampling member of an animal identification tool according to a third embodiment of the present invention.

  The general principle of the present invention is that the male part of the animal identification tool used to stiffen or stiffen the male part along its longitudinal axis during the work of taking a sample of animal tissue and mounting the identification tool. Rely on temporary stiffening.

  Such a stiffening means according to the present invention is configured to prevent deformation of the shaft along the longitudinal axis of the shaft from the lock head to the shaft base.

  In this way, the male shaft does not deform at all or hardly when the tag is attached. This avoids the risk of poor fitting between the male and female parts and also unsatisfactory healing of the ears due to “bending” of the shaft.

  Note that this stiffness is temporary. In this way, the base of the shaft and the body of the male part can be made of a deformable material. Accordingly, the shaft is reinforced during the operation for collecting animal tissue samples and attaching the identification tool to prevent deformation of the shaft along the longitudinal axis. Once the tag is attached, the shaft base and the shaft body are easily deformed under normal pressure, thus preventing the risk of laceration of the animal's ear, for example when the tag is caught on a fence or similar location.

  Referring to FIG. 1, a first embodiment of a male part according to the present invention is shown.

  Such a male part comprises a shaft 12 extending vertically (or substantially perpendicular) from the base 11, for example designed to hit the first face of the animal's ear. Such a shaft 12 has a main body 121 and a lock head 122. The body 121 is conventionally cylindrical or frustoconical. The head 122 is in the shape of a truncated tip or truncated cone in accordance with common practice. At its base 123, the head 122 defines the shoulder features that are used to secure the male head in the female part cavity when the animal is fitted with an identification tool.

  According to the present invention, it is considered that the longitudinal channel that allows passage of the animal tissue sampling member passes through the shaft 12 from end to end.

  In accordance with the present invention, the shaft 12 comprises stiffening means used to stiffen its longitudinal feel, which is located between the center of the shaft and the distal tip 124 of the head. And at least one abutment element projecting into the channel. The abutment element 13 takes the form of, for example, a toe that defines a bearing area on which at least one bearing element of the sample collection member can be placed when an animal tissue sample is collected.

  In this way, a bearing area closer to the shaft tip 124 than the shaft base 11 is defined, thus reducing or even eliminating the compression of the shaft length during the tagging / sampling operation.

  More specifically, if the shaft has a length L between the shaft base 11 and the distal tip 124 of the head, the one or more abutment elements 13 are equidistant from the shaft base 11 and the shaft The distance from the base 11 is at least L / 2. The one or more abutment elements are preferably located at a maximum distance L / 10 from the distal tip 124 of the lock head.

  In this way, male parts made primarily or entirely of deformable material can be used, thus preventing ear tear problems associated with the identification tag being caught.

  The sample can be collected by inserting the sample collection member shown in FIG. 2 into the longitudinal channel of the male part shown in FIG.

For example, such a sampling member is
A sample collection element 21, for example of the biopsy needle type, having a distal tip 211 with a substantially circular cutting ridge and intended to puncture animal tissue to collect a sample;
A mounting support 22 made, for example, of rigid plastic, which allows the needle to be handled during sampling and tag mounting operations and to be securely mounted on the jaws of the tag mounting tool;
-In some cases, a pusher element 23 that can be guided in parallel into the needle 21 when the sample is taken and can push the collected sample out of the needle 21;
Is provided.

  According to the invention, such a sampling member comprises at least one bearing element 24 that is complementary to the abutment element 13 of the male part. In particular, the distance D between the one or more support elements 24 of the sampling member and the sampling distal tip 211 is such that the one or more support elements 24 have one or more abutment elements. The distal tip for sampling is determined to protrude beyond the shaft 12 when hitting 13.

  As described above, when the tissue sample is collected with the tag attached, the specimen collecting member can perform an operation of cutting and holding the tissue. Further, when the support element of the sample collection member contacts the contact element of the male part, the sample collection member can transmit a force to the male part, and the lock head 122 can be inserted into the female part.

  Here, with reference to FIG. 3A-FIG. 3C, 2nd Embodiment of this invention is shown.

  According to the second embodiment, the male part 30 includes a shaft 32 extending from the base 31. The shaft includes a main body 321 and a head 322. The longitudinal channel of the shaft 32 comprises two substantially cylindrical and concentric portions 34 and 35 having different compartments. Specifically, the transition region 33 between the different compartments 34 and 35 defines an abutment element that forms a bearing region that supports at least one bearing element of the tissue collection member when sampling animal tissue.

  More specifically, the first portion 34 located between the shaft base 31 and the transition region 33 is the second of the second portion 35 located between the transition region 33 and the distal tip of the head 324. A circular portion having a first diameter that is strictly greater than the diameter of

  For example, the first diameter is about 3.6 mm and the second diameter is about 5.6 mm.

  Thus, the transition region 33 defines a crown that can be supported by at least one bearing element of the sampling member.

  Again, if L represents the total length of the shaft, the transition region 33 between the sections 34 and 35 with different sections must be located at a distance from the shaft base 31 at least equal to L / 2. The transition region 33 between the different sections 34 and 35 is preferably located at a maximum distance L / 10 from the distal tip 324 of the head.

  Specifically, the thickness e of the material forming the shaft body 321 in the first and second portions is substantially constant, for example, about 1 mm.

  Thus, the outer sheath of the shaft body 321 follows the channel shape in the longitudinal direction.

  In one variation shown in FIG. 3D, the thickness indicated by e1 of the material that forms the body of the shaft in the portion located in front of the transition region from the shaft base to the male lock head is Less than the thickness indicated by e2 of the material that forms the body of the shaft of the rear portion at that height;

  Thus, the outer sheath of the shaft body 321 follows the channel shape in the longitudinal direction. FIG. 3B provides a more accurate view of the identification system according to the present invention, including the male part 30, the female part 36, and the sampling member 37 as described above.

  Such a sampling member 37 includes a biopsy needle type needle 371, a mounting support portion 372, and, if necessary, a pusher element 373 and a support element 374.

  The female part 36 includes a receiving cap having a cavity 361 for introducing the lock head 322 of the male part 30. In particular, the female part 36 has a retaining ring 362 in the inlet hole of the female part. Such retaining ring 362 includes a flexible strip that prevents the lock head from being removed, for example, used to insert the lock head into the cavity of the female part.

  When the tag is attached and the sample is taken, the needle 371 punctures the animal's skin along the surrounding contact line, and then guides the male part's shaft lock head 322 to the female part's receiving cap to guide the male part. The part 30 and the female part 36 are fitted together.

  The dimensions of the male part 30 are such that when the sampling member is inserted into the longitudinal channel and the bearing element 374 abuts the bearing area defined by the transition area 33, the tip of the hollow needle 371 is located on the shaft 32. Dimensions that protrude from the tip 324 and cut tissue from the animal.

  In this way, the rigidity of the shaft 32 of the male part during sampling / tag mounting is ensured.

  In particular, the distance between the lock head (base 323 or distal tip 324 of the head) and the transition region 33 is such that when the male and female parts are mated together, the material of the transition region that forms the body of the shaft is female. It comes in contact with the base of the component. Thus, the male shaft body 321 defines a blocking region between the lockhead base 323 and the transition region 33, thereby blocking the retaining ring 362 and allowing enhanced tag reliability.

  Once tagged, the sampling member 37 can be retracted by sliding it from the shaft 32 and the tissue sample 38 in the needle 371 can be retrieved.

  In particular, a needle 371 holding a tissue sample 38 can be introduced into the sample tube 39 as shown in FIG. 3C. The tissue sample 38 can be removed from the needle 371 by a thin rod (eg, tag mounting tool rod) pushing the pusher element 373.

  Hereinafter, referring to FIGS. 4A to 4F, this shows a third embodiment of the present invention which can be combined with the above-described embodiment.

  According to this embodiment, the longitudinal channel of the shaft 42 of the male part 40 has three consecutive portions 44, 45 and 46 with different compartments. The first portion 44 has a substantially frustoconical shape. The second portion 45 and the third portion 46 are substantially cylindrical. The three parts 44, 45 and 46 are concentric.

  In particular, the transition area 43 between the second part 45 and the third part 46 forms an abutment element that forms a coronal bearing area that supports at least one bearing element of the tissue sampling member when sampling animal tissue. Is defined.

  Such a transition region 43 is located in the lock bed base 423 at the transition between the shaft body 421 and the shaft head 422. Therefore, when L is the total length of the shaft, the transition region is arranged at a distance greater than L / 2 with respect to the shaft base 41. That is, the bearing area is located as close as possible to the tip 424 of the shaft.

  More specifically, according to this embodiment, the lock head 422 comprises an insert 425 having a hardness greater than the hardness of the material forming the shaft body 421. For example, such an insert 425 can be a metal or plastic insert having a hardness of about 50-70 on the Shore D scale, and the shaft body 421 and shaft base 41 are about 42-55 on the Shore D scale. Of hardness. .

  Such an insert 425 takes, for example, the shape of a truncated cone in which a channel in the longitudinal axis direction extends from end to end. A portion of the bottom of such a cone defines a transition region 43.

  In particular, as shown in FIG. 4C, such an insert includes at least one recess 4251 into which the material used to make the shaft during molding of the male part can flow. In this way, the insert is fully attached to the shaft. Thus, it is preferable to attach the insert to the shaft.

  Further, by using such an insert, when the male part is inserted into the female part, the head 422 is reliably held in the female part.

  FIG. 4D shows a first example sampling member inserted into the male part 40. Such a sampling member comprises a biopsy needle type needle 471, a mounting support portion 472, a pusher element 473, and a bearing element 474.

  According to the example shown in FIG. 4D, the needle 471 has two cylindrical portions, the first portion has a circular cross section with an outer diameter φ1, and the second portion has a circular shape with an outer diameter φ2. It has a cross section (φ1> φ2). The transition area between the first part and the second part defines a bearing element 474.

  Such a bearing element 474 is complementary to the male abutment element 43. Thus, the insert 425 forms a hard shoulder that can support the needle.

  Specifically, the distance D between the bearing element 474 and the distal tip of the needle 471 is such that when the bearing element 474 rests on the abutment element 43, the distal tip of the needle 471 exceeds the shaft 42. It is determined to protrude.

  In this manner, the sampling member performs an operation for cutting and holding the tissue when the lock head 422 is inserted into the female part.

  4E-4F show a second example of a sampling member, either alone or inserted into the male part 40. FIG.

  According to the second embodiment, the sampling member includes a biopsy needle type needle 571, a mounting support portion 572, a pusher element 573, and a support element 574.

  According to this second example, the bearing element 574 takes the form of a ring that is firmly attached to the needle 571. Such a ring can be a ring whose height varies (a few microns to a few millimeters). This can be a simple wire, solder bead, hollow cylinder or the like. Such a ring can also be divided entirely along its height.

  For example, such a ring can be held on the needle 571 by gluing, soldering, clipping, or the like. If this ring is an elastic ring type (for example, Circlip (registered trademark)) or a spring ring, it can be inserted into a groove or a hole formed in the sampling member.

  Such a bearing element 574 is complementary to the male abutment element 43. In this way, the ring firmly fixed to the needle 571 hits and supports the insert 425.

  Specifically, the distance D between the bearing element 574 and the distal tip of the needle 571 is such that the distal tip of the needle 571 protrudes from the shaft 42 when the bearing element 574 rests on the abutment element 43. It is determined as follows.

  In this way, the sample collection member can perform an operation for cutting the tissue and holding the tissue when the lock head 422 is inserted into the female part.

  It should be noted that two examples of sampling members can be used in combination with male parts other than those described with reference to FIGS. 4A-4C, particularly male parts that do not have an insert.

  Furthermore, it should be noted that the one or more bearing elements of the sampling member and / or the abutment element of the male part need not necessarily be crown-shaped. As shown in FIG. 1, these elements can include one or more toes, or any other element that can perform a support / abutment function. According to another example, these elements can take the form of elastic rings (eg of the Circlip® type) or spring rings.

  It should also be noted that in the embodiment shown, the sampling member comprises a biopsy needle. As indicated above, it is only one embodiment, and other sampling elements may be used, such as a thin rod terminating in a tip that can puncture tissue.

  Finally, it should be noted that the base of the male portion can take several forms, regardless of the envisaged embodiment. For example, the base can take the form of a disc or can include an extension that defines a marking surface. Thus, the support can be made larger or smaller depending on the type of animal to be tagged. This marking surface makes it possible to identify the animals by visual identification means, in particular in the form of a display in the form of alphabets, numbers or barcodes. Other identification means such as electronic identification means are also conceivable.

  Of course, the different embodiments are shown purely by way of example and are not exhaustive. In particular, it is possible to combine various possible embodiments.
