Abstract
Method and device for injecting at least one product in an egg for treating the embryo. The method includes perforating a shell and an outer shell membrane on a large end of the egg, and injecting the product into an air chamber of the egg under pressure sufficient for the product to reach the amniotic fluid after passing with pressure through an inner shell membrane.
Claims29
A method for injecting at least one product in an egg for treating an embryo located in the egg, wherein the egg comprises a shell and an outer shell membrane, an air chamber on a large end of the egg and a chamber containing the embryo and an amniotic fluid, both chambers being separated by an inner shell membrane, comprising:
- perforating the shell and the outer shell membrane on the large end of the egg without perforating the inner shell membrane;
- and
- ejecting the at least one product under pressure into the air chamber of the egg and in a direction of the unperforated inner shell membrane,
- wherein the ejection pressure is sufficient for the at least one product ejected under pressure into the air chamber to contact and pass with pressure through the unperforated inner shell membrane to reach the amniotic fluid.
A device for injecting at least one product in an egg for treating the embryo located, in the egg, wherein an egg comprises a shell and an outer shell membrane, an air chamber on a large end of the egg and a chamber containing the embryo and an amniotic fluid, both chambers being separated by an inner shell membrane, comprising:
- a positioning device to substantially center the device in a center of the large end of the egg;
- a perforating and injecting tube having an opened ejecting end able to perforate the shell and the outer shell membrane without perforating the inner shell membrane;
- a moving device to move the perforating and injecting tube from a position outside the egg substantially in the center of the large end of the egg to a position where the opened ejecting end is located inside the air chamber;
- and
- an ejecting device to eject the at least one product under pressure from the opened ejecting end into the air chamber, whereby the at least one product contacts the unperforated inner shell membrane and thereafter passes with pressure through the unperforated inner shell membrane to reach the amniotic fluid.
A method for injecting at least one product in an egg for treating an embryo located in the egg. Wherein the egg comprises a shell and an outer shell membrane, an air chamber on a large end of the egg and a chamber containing the embryo and an amniotic fluid, both chambers being separated by an inner shell membrane, comprising:
- perforating a shell and an outer shell membrane without perforating the inner shell membrane;
- and
- ejecting at least one product into an air chamber to contact and then pass through the unperforated inner shell membrane of the egg to reach the amniotic fluid.
