ABSTRACT:
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.
