摘要

Device for artificial insemination and embryo transfer.A device for artificial insemination and embryo transfer, which comprises a hollow elongated tube (30), and a hollow straw (38), which contains a player body in its interior.Set in the elongated tube (30). A flexible tip (34) is fixed to one end of the elongated tube (30), being engaged with the straw (38).The tip (34) has a passage (52) that communicates with the straw (38), and a tapered part (48) adapted to pass smoothly, the cervical canal of a female.A piston rod (40) is mounted, a slider in the elongated tube (30) and constructed to penetrate inside the straw (38), in order to expel the player body housed in the straw (38).Through the passage (52) of the tip (34) for its axial feed.A retention element is disposed between the elongated tube (30) and the piston rod (40) for restricting an axial movement of the piston rod free within the elongated tube (30).A first gasket (102) is inserted around the elongated tube (30) in order to protect the elongated tube (30) against contamination from infectious materials in the cervical canal.On the occasion of the passage of the device through the cervical canal.A second seal (44) surrounds the tip (34) and the first seal (102), with the purpose to prevent the same are contaminated by infectious materials from the vaginal canal.During insertion of the device into the interior of the vaginal canal.
