| 摘要 |
<p>The invention relates to an egg injection device, including a cylindrical injection needle (32), and a cylindrical punch (31) surrounding the needle (32). A sterilizing fluid passageway (66) is defined by the annular space between the cylindrical injection needle and the surrounding cylindrical punch. A sterilizing fluid entry fitting (67) is provided for adding sterilizing fluid to the passageway (66). Fluid exit openings (70) are provided adjacent to and partially above the lowermost portions of the punch that are most likely to enter an egg (64) during injection. The openings permit a sterilizing fluid to travel from the entry fitting (67), through the passageway (66), and to the exterior surface of the punch (31) so that the sterilizing fluid sterilizes the passageway, the needle, and the portions of the punch that are most likely to enter an egg during injection. <IMAGE> <IMAGE></p> |
