The device consists of an injection system consisting of a rigid outer tubular body (1), wich can be introduced into the abdominal cavity of a sow. This rigid outer tube is, in turn, covered by sterile sheath (2), allowing it to be used in different animals. It contains a coaxial flexible inter tube (3), the distal end of which is connected to a bevelled needle (4), wich can be inserted into the uterine tube (12) at an angle of 45°. The proximal end of the flexible tube is connected to a device (6) comprising a sheath (7) closed at one end by plunger (8) wich moves inside the sheath, allowing for the accurate introduction of small volumes of liquid. |
