Description

Technical field:

[0001] The invention relates to the technical field of animal husbandry, and in particular to an artificial insemination device for equine animals. Background technology:

[0002] When breeding livestock, the animal husbandry industry often uses artificial semen collection and artificial insemination for the purpose of adjusting the estrus and breeding period cycles of livestock and optimizing livestock species characteristics. This not only avoids the transportation of livestock themselves, but also avoids the problems of random breeding period and accidental injuries to livestock caused by livestock mating on their own. Usually, during artificial insemination, a semen gun is used to directly inject the semen collected and stored in the early stage into the reproductive organs of the livestock to be pregnant. However, due to individual differences in livestock, the operating parameters of the semen gun are different. If the semen gun is not inserted into place, it will cause the artificial insemination to fail due to shallow injection. If it is inserted too long, it is easy to cause harm to the livestock.

[0003] Due to the above-mentioned problems, there are currently a variety of sperm injection gun designs based on the peepscope principle, which use camera endoscopy to monitor the operating status at any time during the operation, playing a very significant role in the accuracy of artificial insemination operations. However, related equipment based on the endoscope principle needs to maintain power supply, and the additional heat generated by the power supply equipment has an adverse effect on sperm activity. There is also the problem of lens contamination leading to monitoring errors. The price of related equipment is also high, which seriously restricts the promotion of related breeding technologies. Summary of the invention:

[0004] In view of this, it is necessary to design a sperm injection device for artificial insemination of equine animals to replace the existing sperm injection gun working on the principle of endoscope, and eliminate the influence of camera lenses and electrical devices on equipment cost and electric heating problems.

[0005] The invention discloses an artificial insemination and sperm injection device for equine animals, comprising a tubular frame, a telescopic rod array, a rubber membrane, an inner transmission harness, an outer transmission harness, a harness connection synchronizer and a sperm injection tube; wherein the tubular frame is a herringbone frame, which is divided into an inner branch section, an outer branch section and a connection section, wherein the inner branch section has a greater forward extension length than the outer branch section, wherein there are two telescopic rod arrays, which are respectively arranged at the front ends of the inner branch section and the outer branch section, and wherein there are two rubber membranes, which are respectively coated on the outside of the two telescopic rod arrays;

[0006] The telescopic rod array is composed of a plurality of telescopic rods, the inner transmission harness is installed in the inner branch section, and the outer transmission harness is installed in the outer branch section, both of which are composed of a plurality of transmission wires, the front end of each transmission wire is connected to a telescopic rod for transmission, the harness connection synchronizer is installed in the connection section, each transmission wire in the inner transmission harness is fixedly connected to one of the outer transmission harnesses in the harness connection synchronizer, and an elastic device is provided at the connection point to push the transmission wire toward the telescopic rod array, and transmit to push the telescopic rod outward;

[0007] The two telescopic rod arrays have the same arrangement shape and number of telescopic rods. The telescopic rods at the same position are connected through transmission lines in a harness connection synchronizer and move synchronously. The sperm injection tube is installed in the inner branch section and extends forward through a rubber membrane.

[0008] During operation, the telescopic rod array of the inner branch segment extends into the body of the livestock, and the telescopic rod array of the outer branch segment is located outside the body of the livestock. After the elastic device is released to apply thrust to the transmission line, the telescopic rod of the inner branch segment is pushed out and close to the inner cavity of the livestock. In this process, since the transmission lines are connected one-to-one in the harness synchronizer, the telescopic distance of the telescopic rod on the outer branch segment with a corresponding connection relationship is the same as the telescopic distance of the telescopic rod on the inner branch segment. Due to the retraction tendency of the rubber membrane after being stretched by the telescopic rod, the rubber membrane of the outer branch segment can conformally display the shape of the rubber membrane of the inner branch segment, and the shape is the same as the shape of the inner cavity of the livestock. Therefore, the operator can determine the specific position of the inner branch segment in the livestock body according to the shape display of the rubber membrane of the outer branch segment, thereby realizing precise positioning of the semen injection operation.

[0009] Preferably, the top of each telescopic rod in the telescopic rod array is bonded to the inner surface of the rubber film, so that the bonding point of the rubber film moves with the telescopic movement of the telescopic rod. Under this structure, any connection point between the rubber film and the telescopic rod can move freely, and the display at the outer branch segment will change from ring-based to dot-based, with higher display accuracy.

[0010] Preferably, the inner branch section is provided with an S-shaped curved section, and the rear end of the sperm injection tube extends from the S-shaped curved section. Under this structure, the sperm injection tube can use existing straight equipment, without the need to purchase additional curved equipment, thereby reducing equipment costs.

[0011] Preferably, the elastic force device in the wire harness connection synchronizer is a gas pressure spring, and the gas paths of the gas pressure springs are interconnected to balance the pressure. This structure can make the expansion force of each telescopic rod in the telescopic rod array the same, thereby improving the conformal display accuracy. Alternatively, the elastic force device in the wire harness connection synchronizer is a repulsive magnet device, thereby reducing the equipment cost.

[0012] Preferably, the telescopic action section of the telescopic rod is an extension of the transmission line, and correspondingly, its wiring hole is a branch extension of the transmission wire harness guide hole. Further, the wiring hole is a spiral torsion structure.

[0013] Preferably, the present design also includes a second harness connection synchronizer and a second telescopic rod array, wherein the second harness connection synchronizer is installed on the side of the harness connection synchronizer, and the second telescopic rod array has two groups, which are respectively arranged at the front end of the telescopic rod array of the inner branch section and the outer branch section, and the length of the telescopic rod in the second telescopic rod array is longer than the length of the telescopic rod in the telescopic rod array, and is Y-shaped in the extended state, and the two groups of the second telescopic rod array are connected and synchronized through the inner transmission harness, the outer transmission harness, and the second harness connection synchronizer. The second telescopic rod array is used to unfold and conform to the shape of the livestock uterus, displaying the shape characteristics of the uterus, and its Y-shaped structure in the extended state can completely fill the uterine horn and conform to the shape of the inner wall of the uterus completely. The operator can use this conformal display to confirm whether the livestock uterine wall has inflammation, swelling, congestion, scab hardening, and other problems that may affect insemination and fertility before the sperm injection operation.

[0014] Furthermore, the elastic device in the second harness connection synchronizer is a magnet device, wherein the magnet is provided with a rotating handle, and the rotating handle is used to rotate the magnetic pole of the magnet therein, so that the magnetic force of the magnet on the connection between the inner transmission harness and the outer transmission harness switches between magnetic attraction and magnetic repulsion. In the working state, the magnet applies magnetic repulsion to the inner transmission harness and the outer transmission harness in the second harness connection synchronizer, so that the second telescopic rod array is unfolded to conformally display the shape of the uterus. During the insertion or extraction of the sperm injection device, the magnet is flipped by the rotating handle, so that the magnet applies magnetic attraction to the inner transmission harness and the outer transmission harness in the second harness connection synchronizer, so that the second telescopic rod array is retracted and reduced in size to facilitate related operations.

[0015] The present invention provides an artificial insemination and sperm injection device for equine animals, which realizes precise positioning of sperm injection operation through conformal display of interconnected array telescopic rods, eliminates the influence of temperature increase of endoscope electrical equipment on sperm activity, and significantly reduces equipment cost.

Specific implementation method:

[0021] The invention discloses an artificial insemination and sperm injection device for equine animals, comprising a tubular frame, a telescopic rod array 2, a rubber membrane 3, an inner transmission harness 4, an outer transmission harness 5, a harness connection synchronizer 6 and a sperm injection tube 7; wherein the tubular frame is a herringbone frame, which is divided into an inner branch section 101, an outer branch section 102 and a connecting section, wherein the inner branch section 101 has a forward extension length greater than that of the outer branch section 102, wherein there are two telescopic rod arrays 2, which are respectively arranged at the front ends of the inner branch section 101 and the outer branch section 102, and wherein there are two rubber membranes 3, which are respectively coated on the outside of the two telescopic rod arrays 2.

[0022] The telescopic rod array is composed of multiple telescopic rods 201, the inner transmission harness 4 is installed in the inner branch section 101, and the outer transmission harness 5 is installed in the outer branch section 102. They are all composed of multiple transmission wires 202. The front end of each transmission wire 202 is connected to a telescopic rod 201 for transmission. The harness connection synchronizer 6 is installed in the connecting section. Each transmission wire 202 in the inner transmission harness 4 is fixedly connected to a transmission wire 202 in the outer transmission harness 5 in the harness connection synchronizer 6. The connection point is provided with an elastic device to push the transmission wire 202 toward the telescopic rod array 2, and transmit to push the telescopic rod 201 outward.

[0023] The arrangement, shape and number of the telescopic rods 201 of the two telescopic rod arrays 2 are the same. The telescopic rods 201 at the same position are connected in the harness connection synchronizer 6 through the transmission line 202 and move synchronously. The sperm injection tube 7 is installed in the inner branch section 101 and extends forward from the rubber membrane 3.

[0024] The top end of each telescopic rod 201 in the telescopic rod array 2 is bonded to the inner surface of the rubber membrane 3 , so that the bonding point of the rubber membrane 3 moves with the telescopic movement of the telescopic rod 201 .

[0025] The inner branch section 101 is provided with an S-shaped curved section, and the rear end of the sperm injection tube 7 extends from the S-shaped curved section. Under this structure, the sperm injection tube 7 can use existing straight equipment, without the need to purchase additional curved equipment, thereby reducing equipment costs.

[0026] The elastic device in the harness connection synchronizer 6 is a gas spring, and the gas paths of the gas springs are interconnected to balance the pressure. This structure can make the expansion force of each telescopic rod 201 in the telescopic rod array 2 the same, thereby improving the conformal display accuracy.

[0027] The telescopic action section of the telescopic rod 201 is an extension of the transmission line 202, and its wiring hole is a branch extension of the transmission wire harness guide hole. The wiring hole is a spiral torsion structure, which allows the transmission line 202 to turn smoothly to prevent the device from getting stuck.

[0028] During operation, the telescopic rod array 2 of the inner branch segment 101 extends into the body of the livestock, and the telescopic rod array 2 of the outer branch segment 102 is located outside the body of the livestock. After the elastic device is released to apply thrust to the transmission line 202, the telescopic rod 201 of the inner branch segment 101 is pushed out and close to the inner cavity of the livestock. In this process, since the transmission line 202 is connected one-to-one in the harness synchronizer 6, the telescopic distance of the telescopic rod 201 on the outer branch segment with a corresponding connection relationship is the same as the telescopic distance of the telescopic rod 201 on the inner branch segment. Due to the retraction trend of the rubber membrane 3 after being stretched by the telescopic rod 201 and the adhesion between the top of the telescopic rod 201 and the rubber membrane 3, the rubber membrane 3 of the outer branch segment 102 can conformally display the shape of the rubber membrane 3 of the inner branch segment 101 in a dot matrix manner, and the shape is the same as the shape of the inner cavity of the livestock. Therefore, the operator can determine the specific position of the inner branch segment 101 in the livestock body according to the shape display of the rubber membrane 3 of the outer branch segment 102, thereby realizing precise positioning of the injection operation.

[0029] The present design also includes a second harness connection synchronizer 8 and a second telescopic rod array 9, wherein the second harness connection synchronizer 8 is installed on the side of the harness connection synchronizer 6, and the second telescopic rod array 9 has two groups, which are respectively arranged at the front end of the telescopic rod array 2 of the inner branch section 101 and the outer branch section 102, and the length of the telescopic rod 201 in the second telescopic rod array 9 is longer than the length of the telescopic rod 201 in the telescopic rod array 2, and is Y-shaped in the extended state, and the two groups of the second telescopic rod array 9 are connected and synchronized through the inner transmission harness 4, the outer transmission harness 5 and the second harness connection synchronizer 8. The second telescopic rod array 9 is used to unfold and conform to the shape of the livestock uterus, and display the shape characteristics of the uterus. Its Y-shaped structure in the extended state can completely fill the uterine horn and conform to the shape of the inner wall of the uterus. The operator can use this conformal display to confirm whether the livestock uterine wall has inflammation, swelling, congestion, scab hardening and other problems that may affect insemination and fertility before the sperm injection operation.

[0030] The elastic device in the second harness connection synchronizer 8 is a magnet device, wherein the magnet 801 is provided with a handle 802, and the handle 802 is used to rotate the magnetic pole of the magnet 801, so that the magnetic force of the magnet on the connection between the inner transmission harness 4 and the outer transmission harness 5 switches between magnetic attraction and magnetic repulsion. In the working state, the magnet 801 applies magnetic repulsion to the inner transmission harness 4 and the outer transmission harness 5 in the second harness connection synchronizer 8, so that the second telescopic rod array 9 is unfolded to conformally display the shape of the uterus; in the process of inserting or removing the sperm injection device, the magnet 801 is flipped by the handle 802, so that the magnet 801 applies magnetic attraction to the inner transmission harness 4 and the outer transmission harness 5 in the second harness connection synchronizer 8, so that the second telescopic rod array 9 is retracted and reduced in size to facilitate related operations.
