This device is of the type comprising a hollow cylindrical body for receiving at one end a semen reservoir-tube with which are associated means for maintaining the reservoir-tube on the body. Also provided in the body is a slidably mounted plunger-rod which projects from the end of the body opposed to the reservoir-tube. This plunger-rod is adapted to expel semen contained in the reservoir-tube, the plunger-rod cooperating with means for advancing the plunger-rod in a step-by-step manner and actuated by a periodic actuating means. The step-by-step advancing means comprise an advancing element which is provided with an aperture and is mounted with a small clearance on the plunger-rod. This element bears, by the side thereof opposed to the reservoir-tube, on one hand, against a fixed stop member located to one side of the plunger-rod and, on the other hand, against a member which constitutes the periodic actuating means and which is movable in translation in a direction parallel to the plunger-rod between a first position which is situated in confronting relation to the fixed stop member and a second position which is offset toward the reservoir-tube. Return means are provided for returning the actuating means to the first position thereof.
An artificial insemination device for small animals, comprising a hollow cylindrical body, a plunger-rod slidably mounted in the body and projecting from a first end of the body, a periodic actuating means, a step-by-step advancing means cooperative with the plunger-rod and comprising an advancing element which is provided with an aperture and is mounted on the plunger-rod with a small clearance between the advancing element aperture and the plunger-rod and which bears against the periodic actuating means, which actuating means is mounted to be movable in translation relative to the body in a direction parallel to the plunger-rod between a first position and a second position, return means cooperative with the actuating means to return the actuating means to said first position, the hollow cylindrical body being adapted to receive at a second end thereof opposed to said first end a semen reservoir-tube, means associated with said second end of the body for maintaining the reservoir tube on the body, a stop means mounted to be adjustable in position relative to the body in a direction substantially parallel to the plunger-rod, said actuating means being in bearing relation to said stop means in said second position.
An artificial insemination device for small animals in combination with support means for the device, the device comprising a hollow cylindrical body, a plunger-rod slidably mounted in the body and projecting from a first end of the body, a periodic actuating means, a step-by-step advancing means cooperative with the plunger-rod and comprising an advancing element which is provided with an aperture and is mounted on the plunger-rod with a small clearance between the advancing element aperture and the plunger-rod and which bears against the periodic actuating means, which actuating means is mounted to be movable in translation relative to the body in a direction parallel to the plunger-rod between a first position and a second position, return means cooperative with the actuating means to return the actuating means to said first position, the hollow cylindrical body being adapted to receive at a second end thereof opposed to said first end a semen reservoir-tube, means associated with said second end of the body for maintaining the reservoir tube on the body, a stop means mounted to be adjustable in position relative to the body in a direction substantially parallel to the plunger-rod, said actuating means being in bearing relation to said stop means in second position, said support means comprising a support unit, a fixing unit for the body of the device mounted on the support unit to slide along a sliding axis, the body being disposed on the fixing unit in such manner that the plunger-rod is parallel to said sliding axis, a thrust unit rigid with the fixing unit, the thrust unit comprising a thrust member which would be disposed along said sliding axis substantially in lateral alignment with an orifice of a semen reservoir-tube when the reservoir-tube is mounted on the body, the periodic actuating means comprising a member which projects in a position of rest thereof from said first end of the body of the device and is located in confronting relation to a supporting stop means rigid with the support unit.
