Description

An insemination device for mare insemination

technical field

The utility model relates to an artificial insemination device for impregnating the uterus of a mare, in particular to an insemination device for insemination of a mare.

Background technique

The existing mare insemination device is composed of a rubber tube and a glass syringe. When in use, the rubber tube copper rod is first used to guide the mare and the cervix is fixed, and then the diluted male semen is sucked into the syringe and connected with a rubber tube. The injection port of the syringe, push the syringe to inject the semen of the stallion into the uterus of the mare, but it is easy to have backflow of semen after the dryad is completed, the amount of semen used is large, the conception rate is low during estrus, and insemination is difficult, and frozen semen tubes are not suitable Insemination in the existing frozen fine tube.

Utility model content

The purpose of this utility model is to provide an insemination device for mare insemination, which has a reasonable structure, is suitable for breeding with thin tube semen, can effectively inseminate to the uterus of a mare, recover and store fine tubes, and use less semen , Improve conception rate.

The purpose of this utility model is achieved as follows: an insemination device for mare insemination, including a plastic catheter and a push rod, a sperm storage tube is arranged in the plastic catheter, and a sliding plug is arranged in the sperm storage tube and connected with the sperm storage tube. The inner peripheral wall of the seminiferous tube is sealed and dynamically fitted, and the front end of the plastic catheter is fixed with a flexible tubular plastic guide. The tube wall of the flexible tubular plastic guide is solid, the aperture of the tube is smaller than the diameter of the seminiferous tube, and the push rod is installed in the plastic catheter in a moving fit, and is inside the plastic catheter at the front end of the push rod. A piston rod is arranged, and the outer peripheral wall of the piston rod is in dynamic cooperation with the inner peripheral wall of the sperm storage tube. The front end of the piston rod cooperates with the rear end of the sliding plug. The sum L _A of the rod lengths is adapted to the length L _B of the plastic conduit.

When the utility model is in operation, first place the sperm storage tube with the stallion semen and the sliding plug in advance in the plastic catheter, make the piston rod provided at the front end of the push rod extend into the seminal tube to withstand the sliding plug, and then Insert the plastic catheter with a flexible tubular plastic guide at the front end into the uterus of the mare, and push the push button firmly connected to the rear end of the push rod. During the process of pushing the push button, the front end of the piston rod keeps sliding forward The plug pushes the semen in the seminiferous tube out of the seminiferous tube, and because the seminiferous opening of the flexible tubular plastic guide is smaller than the front end of the seminiferous tube, the front end of the seminiferous tube is pushed against the flexible tubular plastic guide. The semen pushed out of the seminiferous tube is then injected into the uterus of the mare through the opening of the front end of the catheter through the sperm outlet hole set at the front end of the flexible tubular plastic guide until the push button is pressed against the retaining ring fixed at the rear end of the catheter. Since the length of the piston rod matches the length of the seminiferous tube, all the semen in the seminiferous tube is pushed out and injected into the uterus of the mare. On the piston rod, pull back the push rod, and at the same time as the piston rod retreats, the seminiferous tube is also brought back, so that the seminiferous tube can be taken out of the plastic catheter conveniently, and the operation of injecting sperm to conceive the mare is completed once. The utility model has a reasonable structure, is suitable for breeding with thin tube semen, can effectively inseminate the sperm into the uterus of a mare, recover the seminiferous tube, use a low amount of semen, and increase the conception rate.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing.

Accompanying drawing is the structural representation of the utility model.

Detailed ways

An insemination device for mare insemination, as shown in the accompanying drawings, includes a plastic catheter 5 and a push rod 7, a seminiferous tube 4 is arranged in the plastic catheter 5, and a sliding plug 3 is arranged in the seminiferous tube 4 And with the inner peripheral wall of the seminiferous tube 4 sealing movement, the front end of the plastic catheter 5 is fixed with a flexible tubular plastic guide 2, the flexible tubular plastic guide 2 wraps the front end nozzle of the plastic catheter 5, and the front end of the plastic catheter 5 The opening communicates with the sperm discharge hole 1 provided at the front end of the flexible tubular plastic guide 2. The tube wall of the flexible tubular plastic guide 2 is a solid body, and the diameter of the sperm discharge hole 1 is smaller than that of the sperm storage tube 4. The push rod 7 moves Cooperate and installed in the plastic conduit 5, the piston rod 6 is arranged in the plastic conduit 5 at the front end of the push rod 7, the outer peripheral wall of the piston rod 6 is in dynamic cooperation with the inner peripheral wall of the sperm storage tube 4, and the front end of the piston rod 6 cooperates to withstand the back of the sliding plug 3 end, the end of the plastic conduit 5 is provided with a retaining ring 8, and the end of the push rod 7 is provided with a push button 9, and the sum L _A of the length of the piston rod 6 and the length of the push rod is adapted to the length L _B of the plastic conduit 5.

The piston rod 6 is a copper rod; the push rod 7 is an iron rod.
