Drawer type efficient oocyte or embryo freezing loading rod

Abstract

The invention relates to a drawer-type high-efficiency oocyte or embryo freezing loading rod, which includes a loading box, a carrier component and a marking plate. The marking plate is arranged on the loading box, and the loading box is side-opened Cubic structure, the interior of the loading box is divided into multiple freezing cavities by multiple partitions, the carrier assembly includes a connecting plate and a plurality of loading rods, one end of the loading rod is connected to the connecting plate, and the connecting plate of the carrier assembly is passed through a tight The fixing device is closely matched with the loading box body, and the loading rod is located in the freezing cavity. The invention has the advantages of improving storage space utilization and freezing efficiency of the freezing tank, and reducing the cost of purchasing liquid nitrogen tanks and liquid nitrogen; in addition, the loading rod is located in the freezing cavity and is completely protected by the loading box, and the embryo or oocyte Cells will not shake in liquid nitrogen, nor will it cause loss of embryos or oocytes; the marker plate has a larger area, which can mark more relevant information, improve the accuracy of recording, and is not easy to be confused.

Description

technical field [0001] The invention relates to a freezing loading rod, in particular to a drawer-type high-efficiency oocyte or embryo freezing loading rod. Background technique [0002] Existing vitrification loading rods are generally referred to as a frozen blade with a flat front end made of a polymer material. During use, egg cells or embryos are placed on the blade for cryopreservation. At the same time, it is also convenient for thawing and recovery when needed in the future, but the carrier device is completed under normal vision monitoring. The leaves with cells or embryos are quickly frozen with liquid nitrogen, and plastic tubes are placed on the outside, and then Put it into the freezing liquid again for preservation. [0003] The problem when using the above-mentioned carrier device is: because the liquid nitrogen temperature is -196 degrees, the blade for placing the embryo needs to be installed on a longer handle, and because the blade is soft, a sleeve must...

Problems solved by technology

[0003] The problem when using the above-mentioned carrier device is: because the liquid nitrogen temperature is -196 degrees, the blade for placing the embryo needs to be installed on a longer handle, and because the blade is soft, a sleeve must be added outside the blade, which causes The cross-section is larger and longer, and the embryo freezing rod is about 21 cm long

This results in a waste of liquid nitrogen tanks and liquid nitrogen
