Problems solved by technology

The successful development of this device makes it possible to inject extremely complex and expensive materials, such as vaccines
However, the size and position of the internal chambers and structures of bird eggs is very variable, and sometimes some eggs need to be injected in non-optimal positions

Embodiment Construction

[0058] Detailed description of the preferred embodiment

[0059] The invention will now be described in more detail with reference to the accompanying drawings, which show preferred embodiments of the invention.

[0060] It should be noted below that, as disclosed in U.S. Patent No. 5,136,979 to Paul et al., the present invention is particularly well suited for injecting material into multiple eggs in a high-speed device without aspirating material from the eggs, the entirety of which is described above. The disclosure of the patent is incorporated herein by reference.

[0061] The present invention is suitable for manipulation of eggs, in particular bird eggs, more preferably poultry eggs, such as chicken eggs, turkey eggs, duck eggs, goose eggs, quail eggs, wild eggs or ostrich eggs. These eggs may be fresh eggs; that is, the eggs contain live avian embryos. Fresh eggs can be at any stage of embryonic development, including early embryonic development and late embryonic de...

Abstract

A method of injecting a plurality of bird eggs comprises: (a) orienting a plurality of avian eggs in a predetermined position; (b) forming an opening in the shell of each of the eggs; (c) extending an elongate delivery device through each of the openings and into the eggs, each of the delivery devices comprising a detector and an injection needle, with the injection needle having a lumen formed therein; (d) detecting with the detector information from the interior of each of the plurality of eggs; and (e) injecting a substance into each of the plurality of eggs through the lumen of said injection needle. The detected information can be used for a variety of purposes, including adjusting the depth of penetration of the injection needle to more precisely control the location of the injection, identifying the gender of the eggs for subsequent sorting of the eggs, distinguishing viable from non-viable eggs, etc. When used for controlling depth penetration, the method positions the needle tip for any purpose, including withdrawing biological material as well as injecting substances. Apparatus, particularly high-speed apparatus, for carrying out the method is also disclosed.

Description

[0001] related application [0002] This invention is based on US Provisional Application No. 60 / 114,933, filed January 6,1999. technical field [0003] The present invention relates to a method and a device for injecting eggs, in particular living embryonic developing avian eggs. Background technique [0004] There are many reasons for injecting substances into birds' eggs, including reducing post-hatch mortality, increasing potential growth rates or homogenizing final chick size, and even affecting embryo sex. Similarly, viruses can also be injected into live eggs to produce virus for use in vaccines. [0005] Examples of such substances introduced into embryonally developing eggs by in-egg injection include live culture vaccines, antibiotics, vitamins and competitive exclusion media such as live replicable tissues. Examples of treatment substances are described in US Patent 4,458,630 to Sharma et al. and US Patent 5,028,421 to Fredericksen et al. See also US Patent 4,4...
