Methods an apparatus for accurately and reliably positioning a device within an egg are provided. An opening is formed within a portion of the shell of an egg and a device is extended through the opening. The device includes a needle having a lumen containing a fluid under pressure. Fluid pressure is monitored and, in response to detecting a change in pressure of the fluid, movement of the device is stopped. Alternatively, fluid flow is monitored and, in response to detecting fluid flow from the needle, movement of the device is stopped. The device may be a substance delivery device that is configured to deliver a substance into the subgerminal cavity of the egg. The device may be a substance removal device that is configured remove a substance from an egg.
Cette invention concerne des techniques et un dispositif permettant de positionner avec précision et fiabilité un dispositif dans la cavité de segmentation d'un oeuf aviaire. Après formation d'une ouverture dans une partie de la coquille de oeuf, on fait passer un dispositif au travers de ladite ouverture. Ledit dispositif comprend un aiguille dont la lumière contient un fluide sous pression. On surveille la pression du fluide. Lorsqu'une variation de cette pression est détectée, on stoppe le mouvement du dispositif. En variante, on peut surveiller l'écoulement du fluide et arrêter le mouvement du dispositif lorsque le fluide s'écoule de l'aiguille. Le dispositif peut être utilisé pour introduire une substance dans la cavité de segmentation, ou bien être conçu pour aspirer une substance hors de oeuf.
