The invention relates to a device for controlling a flow circulating in the lumen of a male vas deferens, comprising a clamp configured to coaxially grasp an outer wall of the vas deferens and a long, slender element coupled to the clamp, a distal portion of which is adapted to be at least partially inserted into the vas deferens. Said distal portion has a deflection tube adapted to divert said flow out of the vas deferens when an inlet of said deflection tube is aligned with the lumen. Abstract figure: Fig. 1

The application discloses a kind of built-in anti-ejaculation devices of stallion, it is related to the technical field of animal husbandry, including placing hose, support tube is placed in the inside of placing hose;The outer side wall of the open end of support tube is installed with snap ring, and the opposite surface of snap ring is installed with fixed assembly;One of snap ring is in abutment with the inner side wall of placing hose, and the other snap ring is in abutment with the opening of placing hose.The application discloses a kind of built-in anti-ejaculation devices of stallion, not only can realize the filtration of sperm of stallion, but also can make that tissue fluid can normally flow and avoid vas deferens congestion, and will not affect normal mating behavior of stallion, further, anti-ejaculation behavior is reversible, does not affect stallion recovery reproductive capacity in later period, overall built-in structure design is compact, fixed assembly is assembled firmly, can be long-term retained and used, no exposed component, safe and non-irritating, adapt to stallion physiological structure, and practicality is strong.

1. Name of the designed product: insemination tube (single tube). 2. Use of the designed product: insemination tube for veterinary use. 3. Design points of the designed product: in shape. 4. Picture or photo that best shows the design points: perspective view.

The application discloses a vas deferens contraceptive device and a preparation method thereof, and relates to the technical field of medical devices. The device comprises a tubular outer wall, the inside of the tubular outer wall is filled with a sperm blocking layer and a mechanical support layer, the sperm blocking structure is a pore structure that can block sperm, and the mechanical support structure is a three-period minimal surface structure. The combination of the two structures can prevent sperm from passing through the vas deferens while ensuring the normal passage of tissue fluid. The device is mainly prepared through three steps of model slice design, ink configuration, 3D printing and device post-processing. Compared with vasectomy, the vas deferens contraceptive device and the preparation method thereof can avoid complications and fertility damage caused by epididymal stasis, and the implantation of the device has a smaller incision than vasectomy and is convenient for processing and manufacturing.

The invention relates to a device for controlling a flow circulating in the lumen of a vas deferens of a male individual, comprising a clamp configured to coaxially grip an outer wall of the vas deferens and an elongate element configured to be coupled to the clamp, a distal portion of which is adapted to be at least partially introduced into the vas deferens. Said distal portion comprises a diversion tube adapted to divert said flow out of the vas deferens when an inlet of said diversion tube is aligned with the lumen.

Compositions, devices, and methods of using one or more hydrogel for contraception are disclosed. In embodiments, the compositions and devices comprise one or more contrast agent, rendering the compositions and devices radiopaque. Included are compositions for an occlusive implant comprising: a multi-arm polyethylene glycol terminated with a thiol crosslinked with a multi-arm polyethylene glycol terminated with a maleimide; and one or more contrast agent. The devices / hydrogel may be used for occlusion of a bodily duct, such as the vas deferens and / or fallopian tubes, for male and female contraception, respectively.

The utility model relates to the field of artificial insemination for pigs, and discloses a sanitary insemination tube for artificial insemination for pigs, which comprises a fixed tube, a push rod is slidably connected to the inner wall of the right end of the fixed tube, a fixed block is fixedly connected to the outer wall of the fixed tube, and a movable plate is slidably connected to the outer wall of the fixed tube. A guide rod is fixedly connected to the outer wall of the right end of the moving plate, a threaded rod is rotationally connected to the inner wall of the right end of the moving plate, and a sealing assembly is arranged on the inner wall of the left end of the fixing pipe and used for sealing an opening in the left end of the fixing pipe. According to the device, the threaded rod is rotated to drive the movable plate to move, the distance between the outer wall of the left end of the movable plate and the left end of the fixed tube is adjusted according to the depth of the left side of the seminiferous duct moving into the vagina of the sow, and after adjustment is completed, the left side of the seminiferous duct can quickly and accurately move to the semen releasing position in the vagina of the sow according to the position of the movable plate. The artificial fertilization of the sows with the same body type is facilitated.

The utility model relates to a kind of combined non-surgical method super-deep embryo transfer insemination tube for pig, and the transfer tube includes: ordinary insemination tube, super-deep insemination tube and super-deep embryo transfer tube, which is used for the transport of embryo or semen after combination. The ordinary insemination tube is used for inserting into vagina dilatation cervix, so that the super-deep insemination tube can pass through vagina and cervix. The super-deep insemination tube has a metal connector and a silicone soft tip at its front end. The super-deep embryo transfer tube has a standard luer taper syringe interface at its tail end. Compared with the prior art, the utility model is specially developed according to the existing problems of non-surgical embryo transfer, and is innovative on the basis of retaining the advantages of non-surgical embryo transfer. Under the visual field, the catheter can be accurately inserted into the specified position, which can prevent embryo reflux and effectively solve the problems of blind insertion method, such as uncontrollable insertion depth, bending of embryo transfer tube and embryo reflux, thereby improving the efficiency of non-surgical embryo transfer pregnancy delivery.
