ABSTRACT:
A sterilizing fluid passageway is defined by the annular space between a cylindrical injection needle and a surrounding cylindrical punch. A sterilizing fluid entry fitting allows the sterilizing fluid to be added to the passageway. In this manner, it will be understood that sterilizing fluid entering a fitting will travel through the passageway to clean the interior of a punch and an exterior of the needle. As an additional feature, however, the invention further comprises fluid exit openings that are adjacent to and partially above the lowermost portions of the punch, i.e., those portions that are most likely to enter an egg during injection. The openings permit a sterilizing fluid to travel from the entry fitting through the passageway and then to the exterior surface of the punch so that the sterilizing fluid sterilizes the passageway, the needle and both the interior and exterior portions of the punch that are most likely to enter an egg during injection.
