摘要：The invention relates to a device for drawing and injecting liquid substances, carrier liquid mixtures, cells or tissues, used in particular for drawing or injecting doses of blood, spermatozoa or ovocytes, the device also being usable for artificial insemination or embryo transfer by transcervical or transperitoneal means, this device consisting of a syringe formed by an external sheath 4 in which a suction and delivery plunger 3 slides, with the absence of leaks. This device is characterised in that it comprises a control handle 1, ensuring the control of the piston 3, formed by a handle which is passed through axially by a pipe 2 in which the rear end of the said plunger is moved, a rotary driving member 7 being mounted tangentially to this plunger 3 in order for the latter to be movable with one hand, by simple pressure and movement of the thumb. <IMAGE>
