Egg freezing and storing tool and method

摘要

An egg freezing and storing instrument has an egg freezing and storing tube made of a liquid nitrogen-resistant material; and a metal cylindrical protection member for protecting the tube. The tube has a body part; and an egg-storing small-diameter part having an inner diameter of 0.1 mm to 0.5 mm. The tube can be heat-sealed at a front side of the small-diameter part and at a rear side of the body part. The cylindrical protection member has a tubular part for accommodating a front side of the small-diameter part of the tube; and a semi-tubular part for accommodating a portion of the small-diameter part not accommodated in the tubular part and a front portion of the body part.
