Description

Title of the invention: Artificial insemination device for livestock, particularly pigs. TECHNICAL FIELD OF THE INVENTION

[0001] The invention relates to an artificial insemination device for livestock, in particular pigs. STATE OF THE ART

[0002] Artificial insemination devices for livestock, particularly pigs, are also called insemination probes or catheters.

[0003] These insemination probes are generally made at least partially of plastic material and, as these probes are for single use, they must be disposed of and recycled after use.

[0004] In particular, such an insemination probe comprises a tubular longitudinal body made of plastic, in particular polypropylene, and a foam tip, in particular polyurethane, which is attached at one end of the body and which is configured to be inserted and positioned in the cervix of a female animal, with the tip thus forming a functional end of the probe.

[0005] Such a probe further has a seed flow channel extending longitudinally from an inlet end inside the probe body to an outlet end, opposite the inlet end, inside a through orifice provided in the tip, where the flow channel opens.

[0006] A sachet containing semen, for example porcine, is generally connected directly or indirectly, via a conduit, to the inlet end of the flow channel so that, once the probe is positioned in the cervix of the female animal, the semen can flow from the sachet into the female animal through the body and tip of the probe.

[0007] Such use requires that the insemination probe have certain specific parameters, in particular mechanical resistance, safety with regard to the semen to be transferred, and stability over time, which are met, for example, by polypropylene for the body and polyurethane foam for the tip. Description of the invention

[0008] The invention relates to a single-use artificial insemination device for livestock, particularly pigs, which is particularly environmentally friendly while being simple, convenient and economical.

[0009] The invention thus relates to an artificial insemination device for livestock, particularly pigs, comprising a tubular body and a nozzle attached to the at one end of the tubular body and configured to be inserted and positioned in the cervix of a female animal, characterized in that the tip is composed of at least agar-agar, water and glycerol.

[0010] In the artificial insemination device according to the invention, the tip is made from components which have characteristics of biodegradability and home compostability.

[0011] It should be noted that agar-agar is a gelling agent found in particular in the cell walls of certain species of red algae belonging to the Gelidiaceae and Gracilariaceae families. Agar-agar can be in powder form which, upon contact with water, forms a gelatinous mucilage.

[0012] In addition, the artificial insemination device according to the invention not only ensures its function of assisting in the insemination of farm animals, particularly pigs, which requires both sufficient compressibility and relative hardness of the tip while maintaining stability over time, particularly in terms of mass, for its positioning and retention in the cervix of the female animal, but also allows for single use and disposal without any restrictive recyclability requirements.

[0013] In particular, the combination of agar-agar and glycerol to form the tip makes it possible to obtain satisfactory dimensional and mass properties over time, as well as mechanical properties defined by a Young's modulus and an elongation at break that are also satisfactory for the use of the insemination device equipped with such a tip; whereas the tip of such an artificial insemination device can simply decompose as a result of biological processes in a home compost, without any particular action other than the action of time.

[0014] Preferred, simple, convenient and economical features of the artificial insemination device according to the invention are presented below.

[0015] The tip may contain between approximately 3% by weight and approximately 5% by weight of agar-agar.

[0016] The tip may contain approximately 3.6% by weight of agar-agar.

[0017] The nozzle may contain between approximately 40% by weight and approximately 60% by weight of glycerol.

[0018] The tip may contain talc, so as to reinforce the mechanical properties of the tip, particularly over time.

[0019] The tip may contain less than 10% by weight of talc.

[0020] The tip may contain between approximately 8% by weight and approximately 9% by weight of talc.

[0021] The tip may contain approximately 8.3% by weight of talc.

[0022] Values ​​expressed as a percentage by weight are equivalent to values ​​of mass percentage or percentage by mass.

[0023] The tip may have a first determined length in an initial state, and a second length less than the first determined length in a first subsequent state measured approximately 24 hours after the initial state.

[0024] The second length may be less than approximately 2 mm to approximately 7 mm than the first determined length.

[0025] The tip may have a first weight determined in an initial state, and a second weight lower than the first weight determined in a second subsequent state measured between approximately 24 hours and approximately 10 days after the initial state.

[0026] The second weight may be less than 20% to less than 50% less than the first determined weight.

[0027] The nozzle may have a Young's modulus between approximately 300 kPa and approximately 500 kPa.

[0028] The tip may exhibit an elongation at break of between approximately 0.6 and approximately 0.8.

[0029] In other words, the tip can be elongated between about 60% of its length and about 80% of its length before tearing.

[0030] The nozzle may have a through orifice into which the tubular body is inserted by its end.

[0031] The through orifice of the nozzle can form a second flow channel extending a first flow channel of the tubular body.

[0032] The tip can be secured by gluing onto the end of the tubular body.

[0033] Other preferred, simple, convenient and economical features of the artificial insemination device according to the invention are also presented below.

[0034] The tubular body can be formed of an inner envelope made of paper and delimiting at least partially a first flow channel in the tubular body for the flow of male animal semen, and of an outer envelope made of a biopolymer material and covering the inner envelope.

[0035] In the artificial insemination device according to the invention, the tubular body is formed of an inner envelope and an outer envelope which have characteristics of biodegradability and home compostability.

[0036] In other words, the artificial insemination device according to the invention not only ensures its function of assisting in the insemination of farm animals, particularly pigs, which requires both sufficient rigidity and relative flexibility of the tubular body, in other words adequate flexing behavior, for its positioning and retention in the cervix of the female animal, but also is single-use and disposable without any binding recyclability requirement.

[0037] In particular, since the inner envelope is made of paper and the envelope The external component is made of a biopolymer material; the artificial insemination device can simply decompose as a result of biological processes in a home compost, without any special action other than the action of time.

[0038] The inner envelope of the tubular body can be provided with an inner sheath formed of several layers of paper of a first type having a first grammage, and an outer sheath formed of at least one layer of paper of a second type having a second grammage different from the first grammage.

[0039] The inner sheath makes it possible in particular to provide the inner envelope and therefore the tubular body with sufficient rigidity while the outer sheath promotes adhesion between the inner envelope and the outer envelope.

[0040] The paper of the first type of the inner sheath may have a first grammage higher than the second grammage of the paper of the second type.

[0041] The inner sheath may comprise between two and four layers of paper of the first type.

[0042] The paper layers of the first type of the inner sheath can be superimposed one around the other and coaxial.

[0043] Alternatively, the paper layers of the first type of the inner sheath can be superimposed by winding.

[0044] At least one of the paper layers of the first type of the inner sheath can be coated with a hydrophobic treatment.

[0045] The paper layers of the first type of the inner sheath can each have a first thickness of between about 100 pm and about 220 pm.

[0046] The paper layers of the first type of the inner sheath can each have a first thickness equal to approximately 160 pm.

[0047] The paper of the first type of the inner sheath may have a first basis weight of between approximately 80 g / m2 and approximately 150 g / m2.

[0048] The paper of the first type of the inner sheath may have a first basis weight of approximately 120 g / m2.

[0049] The paper of the second type may be an opaque paper.

[0050] At least one layer of paper of the second type of the inner sheath may have a second thickness of between about 50 pm and about 120 pm.

[0051] At least one layer of paper of the second type of the inner sheath may have a second thickness equal to about 80 pm.

[0052] The second type of paper in the inner sheath may have a second weight of between approximately 50 g / m2 and approximately 70 g / m2.

[0053] The paper of the second type of the inner sheath may have a second basis weight equal to approximately 60 g / m2.

[0054] The inner shell of the tubular body may have a first thickness cumulative between approximately 350 pm and approximately 800 pm.

[0055] The inner envelope of the tubular body may have a first cumulative thickness equal to approximately 700 pm.

[0056] The outer shell can be made of polybutylene succinate adipate, noted PB SA.

[0057] The outer envelope may have a third thickness of between approximately 200 pm and approximately 500 pm.

[0058] The outer envelope may have a third thickness equal to approximately 300 pm.

[0059] The tubular body may have a second cumulative thickness of between approximately 550 pm and approximately 1300 pm.

[0060] The tubular body may have a second cumulative thickness equal to approximately 1000 pm. BRIEF DESCRIPTION OF THE FIGURES

[0064] Fig. 3 is a longitudinal median cross-sectional view of the artificial insemination device visible in Fig. 1.

[0065] Fig. 4 is a partial perspective view showing the composition of the tubular body. DETAILED DESCRIPTION OF THE INVENTION

[0066] Figures 1 to 3 illustrate an artificial insemination device 1 for livestock, here for pigs.

[0067] The artificial insemination device 1 is for single use and here exhibits properties which make it a biodegradable and domestically compostable artificial insemination device 1.

[0068] The artificial insemination device 1 comprises a tubular body 2 and a nozzle 3 attached to the tubular body 2.

[0069] The artificial insemination device 1 is configured to transfer semen from a male animal into a female animal's genital tract, and in particular here into the female animal's cervix.

[0070] The tubular body 2 is semi-rigid here, that is to say, it exhibits a bending behavior that allows it to be sufficiently rigid while exhibiting flexibility relative so as to ensure its positioning and retention in the cervix of the female animal, for the purpose of insemination.

[0071] The tubular body 2 has a first end 5 and a second end 6 opposite the first end 5.

[0072] The tubular body 2 extends between the first end 5 and the second end 6 over a first determined length.

[0073] The tubular body 2 has a first external diameter and a second internal diameter that is smaller than the first external diameter.

[0074] The tubular body 2 is provided with a first flow channel 7 extending between the first end 5 and the second end 6.

[0075] The first flow channel 7 opens at the first end 5 through a first orifice 8, which defines an inlet orifice of the artificial insemination device 1.

[0076] The first flow channel 7 opens at the second end 6 through a second orifice 9.

[0077] The first flow channel 7 allows the male animal's semen to flow through the tubular body 2.

[0078] The tip 3 is said to be flexible, that is to say, it has both sufficient compressibility and relative hardness for its positioning and retention in the cervix of the female animal, for the purpose of insemination.

[0079] The tip 3 has a third end 12 and a fourth end 13 opposite the third end 12.

[0080] The tip 3 extends between the third end 12 and the fourth end 13 over a second determined length.

[0081] The tip 3 has an overall revolutionary shape.

[0082] In the illustrated example, the third end 12 has a frustoconical shape with an apex angle of approximately 90°.

[0083] In particular, the fourth end 13 here also has a frustoconical shape with an apex angle of approximately 90°.

[0084] The tip 3 has a third external diameter and a fourth internal diameter smaller than the third external diameter.

[0085] The tip 3 is provided with a through orifice defining a second flow channel 14 extending between the third end 12 and the fourth end 13.

[0086] The second flow channel 14 opens at the third end 12 through a third orifice 15 and at the fourth end 13 through a fourth orifice 16 which defines an outlet orifice of the artificial insemination device 1.

[0087] The second flow channel 14 also allows the flow of the seed of the male animal through tip 3.

[0088] The tip 3 also has a circumferential branch 17.

[0089] The groove 17 is formed here approximately halfway along the second determined length of the tip 3.

[0090] In the illustrated example, the tip 3 is further provided with a peripheral groove 18.

[0091] The peripheral throat 18 is formed near the fourth end 13, which forms a distal end of the insemination device 1.

[0092] The peripheral groove 18 here has a circular cross-section and presents a fifth diameter which is less than the fourth internal diameter of the nozzle 3, and which is also less than the second internal diameter of the first flow channel 7 of the tubular body 2.

[0093] In other words, the peripheral groove 18 locally narrows the second flow channel 14 of the tip 3, just before the distal end of the insemination device 1.

[0094] The tubular body 2 is introduced by its second end 6 into the third orifice 15 of the nozzle 3.

[0095] The tip 3 covers and overlaps at least partially, at its third end 12, the second end 6 of the tubular body 2.

[0096] The first internal channel 7 of the tubular body 2 opens at its second orifice 9 into the second flow channel 14 of the nozzle 3.

[0097] Thus, the second flow channel 14 of the nozzle 3 partially extends the first flow channel 7 from the second end 6 of the tubular body 2 to the fourth end 13 of the nozzle 3.

[0098] In other words, the second flow channel 14 of the nozzle 3 partially extends the first flow channel 7 of the tubular body 2 so that the nozzle 3 protrudes beyond the second end 6 of the tubular body 2.

[0099] In the illustrated example, the tip 3 is secured by gluing to the tubular body 2.

[0100] In the artificial insemination device 1, the tubular body 2 is configured as follows to guide, insert and position tip 3 into the cervix of the female animal, for insemination.

[0101] In addition, the tubular body 2 is configured to be attached at its first end 5, in particular by the first orifice 8, to a pouch containing the semen of the male animal, commonly called a sachet-dose.

[0102] In the artificial insemination device 1, the tip 3 is therefore configured to be inserted and positioned in the cervix of the female animal.

[0103] The peripheral groove 18 of the nozzle 3 can be configured to form a kind of deflector in the second flow channel 14 to accelerate the flow of the male animal's semen at the outlet of the artificial insemination device 1.

[0104] Thus, the tip 3 forms a functional end of the artificial insemination device 1, and makes it possible to avoid injuring the female animal with the second end 6 of the tubular body 2.

[0105] As indicated above, the artificial insemination device 1 is for single use and here exhibits properties which make it a biodegradable and domestically compostable artificial insemination device 1.

[0106] In particular, as can be seen in [Fig.4], the tubular body 2 is formed of an inner envelope 20, here made of paper, and an outer envelope 27, here made of a biopolymer material, for example polybutylene succinate adipate, noted PBSA.

[0107] The inner casing 20 is provided with an inner sheath 21 and an outer sheath 25.

[0108] The inner sheath 21 is formed of a first layer 22, a second layer 23 and a third layer 24, each of which is made of paper of a first type having a first weight.

[0109] The first layer 22, the second layer 23 and the third layer 24 are here each made of so-called white paper having a first weight between about 80 g / m2 and about 150 g / m2, and for example equal to about 120 g / m2.

[0110] The first layer 22, the second layer 23 and the third layer 24 each have a first thickness between approximately 100 pm and approximately 220 pm, and for example equal to approximately 160 pm.

[0111] The first layer 22, the second layer 23 and the third layer 24 are here superimposed around each other and coaxial.

[0112] In other words, the second layer 23 is superimposed around the first layer 22, and the third layer 24 is superimposed around the second layer 23, with the first layer 22, the second layer 23 and the third layer 24 being coaxial.

[0113] In addition, at least one of the first layer 22, second layer 23 and third layer 24 of the inner sheath 21 is coated with a hydrophobic treatment.

[0114] The outer sheath 25 is formed here of a fourth layer 26 of paper of a second type having a second weight different from the first weight.

[0115] The fourth layer 26 is here made of opacifying paper, also called kraft paper, having a second weight between about 50 g / m2 and about 70 g / m2, for example equal to about 60 g / m2.

[0116] The fourth layer 26 has a second thickness of between about 50 pm and about 120 pm, and for example equal to about 80 pm.

[0117] The outer sheath 25 of the inner envelope 20 is superimposed around the inner sheath 21, with the outer sheath 25 and the inner sheath 21 being coaxial.

[0118] In other words, the fourth layer 26 of the outer sheath 25 is superimposed around the third layer 24 of the inner sheath 21, with the fourth layer 26 being coaxial with the first layer 22, second layer 23 and third layer 24 of the inner sheath 21.

[0119] The inner envelope 20 here has a first cumulative thickness of between approximately 350 pm and approximately 800 pm, and for example equal to approximately 700 pm.

[0120] The outer envelope 27, for example in PBSA, has a third thickness between about 200 pm and about 500 pm, and for example equal to about 300 pm.

[0121] The outer envelope 27 covers the inner envelope 20 and in particular its outer sheath 25.

[0122] In the illustrated example, the outer envelope 27 is superimposed around the fourth layer 26 of the outer sheath 25 of the inner envelope 20.

[0123] The tubular body 2 has a second cumulative thickness of between approximately 550 pm and approximately 1300 pm, and for example equal to approximately 1000 pm.

[0124] The structure thus described of the inner sheath 21 makes it possible in particular to provide sufficient rigidity to the inner envelope 20 and therefore to the tubular body 2.

[0125] This has been demonstrated in particular by means of bending performance tests, where the tubular body 2 thus formed can bend to form an angle greater than 80°, or even up to 180°, without pinching of the first flow channel 7, and therefore without interruption of the flow.

[0126] The structure of the inner sheath 21 described above also ensures that it is harmless to the seed to be transferred.

[0127] This has been demonstrated in particular by means of toxicity tests of the tubular body 2, by carrying out successive measurements of the motility of spermatozoa present in a sample of semen which flowed into the tubular body 2 of the artificial insemination device 1.

[0128] The structure of the outer sheath 25 described above also promotes adhesion between the inner envelope 20 and the outer envelope 27.

[0129] Furthermore, in the artificial insemination device 1, the tubular body 2 is formed of an inner envelope 20 and an outer envelope 27 which have characteristics of biodegradability and home compostability.

[0130] In particular, since the inner envelope 20 of the tubular body 2 is made of paper and the outer envelope 27 is made of a biopolymer material, the artificial insemination device 1 can simply decompose as a result of biological processes in a home compost, without any special action other than the action of time.

[0131] In other words, the artificial insemination device 1 not only allows to ensure its function of assisting in the insemination of livestock, here for pigs, which requires both sufficient rigidity and relative flexibility of the tubular body 2, in other words adequate flexural behavior, for its positioning and retention in the cervix of the female animal, but also to be single-use and disposable without any binding recyclability requirements.

[0132] In the artificial insemination device 1, the tip 3 also has characteristics of biodegradability and home compostability

[0133] In the illustrated example, the tip 3 is composed of at least agar-agar, water, glycerol and also talc.

[0134] The nozzle 3 comprises between approximately 3% by weight and approximately 5% by weight of agar-agar, and for example approximately 3.6% by weight of agar-agar.

[0135] Agar-agar is a gelling agent found in particular in the cell walls of certain species of red algae belonging to the Gelidiaceae and Gracilariaceae families. Agar-agar can be in powder form which, upon contact with water, forms a gelatinous mucilage.

[0136] Nozzle 3 comprises between approximately 40% by weight and approximately 60% by weight of glycerol.

[0137] The tip 3 contains less than 10% by weight of talc, in particular between about 8% by weight and about 9% by weight of talc, and for example about 8.3% by weight of talc.

[0138] Nozzle 3 contains between approximately 25% by weight and approximately 50% by weight of water.

[0139] The tip 3 has a first determined length in an initial state, and a second length less than the first length determined in a first subsequent state measured approximately 24 hours after the initial state.

[0140] This has been demonstrated in particular through aging tests.

[0141] According to one example, aging tests on a tip as described above containing about 40% by weight of glycerol and having been stabilized at room temperature, show that an aging equilibrium is reached in about 24 hours with a measured length loss of about 4 mm.

[0142] According to another example, aging tests on a tip as described above containing about 40% by weight of glycerol and having been stabilized at a temperature of about 30 °C in a closed chamber, show that an aging equilibrium is reached in about 24 hours with a measured length loss of about 7 mm.

[0143] Similar tests were carried out for tips containing approximately 60% by weight of glycerol, and aging equilibrium was reached in 24 hours with a measured length loss of approximately 2 mm and 4 mm respectively.

[0144] Furthermore, the tip 3 has a first weight determined in an initial state, and a second weight less than the first weight determined in a subsequent second state measured between approximately 24 hours and approximately 10 days after the initial state.

[0145] The second weight may be less than 20% to less than 50% less than the first weight determined, for tips having between about 40% and about 60% by weight of glycerol.

[0146] This has also been demonstrated in particular through aging tests.

[0147] According to one example, aging tests on a tip as described above containing about 40% by weight of glycerol and having been stabilized at room temperature, show that an aging equilibrium was reached in 9 days with a measured weight loss of about 45%.

[0148] According to another example, aging tests on a tip as described above containing about 40% by weight of glycerol and having been stabilized at a temperature of about 30 °C in a closed chamber, show that an aging equilibrium was reached in 24 hours with a measured weight loss of about 47%.

[0149] Similar tests were carried out for tips containing about 60% by weight of glycerol, and aging equilibrium was reached in 9 days at room temperature and in 24 hours at a temperature of about 30 °C with a measured weight loss of about 28% and 27% respectively.

[0150] The tip 3 has certain mechanical properties, defined by a Young's modulus between about 300 kPa and about 500 kPa, and an elongation at break between about 0.6 and about 0.8, which means that the tip can be elongated between about 60% of its length and about 80% of its length before tearing.

[0151] This has been demonstrated by mechanical tests, in particular tensile breakage tests, with tips having, as for the tests described above, different mass percentages of glycerol but also different mass percentages of talc and / or different mass percentages of agar-agar, according to different stabilization methods, either at room temperature for 48h or without stabilization.

[0152] The results of these tests show Young's moduli of approximately 368 kPa, 443 kPa, 477 kPa and 334 kPa and elongations at break of approximately 13%, 22%, 63%, 76%, respectively, for unstabilized tips with approximately 40% by weight of glycerol and 3.6% by weight of agar-agar and 8.3% by weight of talc, unstabilized tips with approximately 60% by weight of glycerol and 3.6% by weight of agar-agar and 8.3% by weight of talc, stabilized tips with approximately 40% by weight of glycerol and 3.6% by weight of agar-agar and 8.3% by weight of talc, and stabilized tips with approximately 60% by weight of glycerol and 3.6% by weight of agar-agar and 8.3% by weight of talc, the rest of the composition of the tip here being formed by water.

[0153] Results for similar tests but with talc-free tips mainly show lower Young's moduli.

[0154] In other words, the talc acts as a filler and helps to improve the mechanical properties of the tip 3.

[0155] Results for similar tests but with tips having different mass percentages of agar-agar mainly show lower Young's moduli when the tip has less agar-agar and higher ones when the tip has more agar-agar, and conversely an elongation at break which decreases with the addition of agar-agar.

[0156] In other words, the tip must contain enough agar-agar to have sufficient mechanical properties and not be brittle.

[0157] To demonstrate the biodegradability and home compostability of the body tubular 2 and the tip of the artificial insemination device 1, tests according to test method ISO 20200 2015, were carried out.

[0158] The results showed that a domestically composted state was obtained in between about 1 month and about 6 months.

[0159] In other words, the artificial insemination device 1 not only ensures its function of assisting in the insemination of livestock, here for pigs, which requires both sufficient rigidity and relative flexibility of the tubular body 2, in other words adequate behavior in bending, and also sufficient compressibility and relative hardness of the tip 3 while maintaining stability over time, in particular in terms of mass, for their positioning and retention in the cervix of the female animal, but also to be single-use and disposable without any binding condition of recyclability.

[0160] Variants not illustrated are described below.

[0161] The percentages by weight correspond to mass percentages or percentages by mass, may have slightly different values ​​from those described above.

[0162] The tip may be free of talc.

[0163] The tip may have a different shape from that described above.

[0164] The nozzle can be fitted onto the tubular body without gluing.

[0165] The artificial insemination device may be a cervical or post-cervical type artificial insemination device.

[0166] More generally, the invention is not limited to the examples described and represented.
