Integrated embryo freezing device

Abstract

The invention discloses an integrated embryo freezing device which comprises an embryo freezing box, a plurality of loading plates and a cover plate. A plurality of partition plates are uniformly fixed in the embryo freezing box from left to right, so that the embryo freezing box is divided into a plurality of freezing chambers; the loading plates are uniformly fixed to the back end surface of thecover plate and are opposite to the freezing chambers in position, and embryo loading grooves are formed in the upper end surfaces of the loading plates, separately. The integrated embryo freezing device has the beneficial effects that the loading plates for loading embryos are integrated to the cover plate which is taken as a supporting plate shared by the loading plate without a handle, so thatthe occupied space can be reduced compared with scattered arrangement of a plurality of conventional carrier rods, the liquid nitrogen tank storage efficiency can be improved greatly and the liquid nitrogen tank storage space is fully utilized when the cover plate is placed on a freezing rack in the liquid nitrogen storage tank. The embryo loading grooves can load embryos needing to be frozen conveniently, so that the embryos are hard to slide and fall off. Therefore, the integrated embryo freezing device is good in using effect.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an integrated embryo freezing device. 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, and embryos are placed on the blade for cryopreservation during use. At the same time, it is also convenient for thawing and resuscitating when needed in the future. However, the carrier device is completed under normal visual supervision. The leaves with the embryos are quickly frozen with liquid nitrogen, and a plastic tube is placed on the outside, and then again. Put into freezing liquid for preservation. [0003] The problems when using the above-mentioned carrier device are: first, because the temperature of liquid nitrogen is -196 degrees, it is necessary to install the blade of the embryo on a longer handle, and because the blade is soft, a sleeve must be added outsi...

Problems solved by technology

[0003] The problems existing in the application of the above-mentioned carrier device are: first, since the temperature of liquid nitrogen is -196 degrees, it is necessary to install the blade of the embryo on a longer handle, and because the blade is soft, a casing must be added outside the blade , so that the cross-section of the entire loading rod formed by the blade and the handle is large and long, so that it takes up a lot of space when it is placed on the freezer shelf in the liquid nitrogen tank, making the storage efficiency extremely low and the liquid nitrogen cannot be fully utilized The storage space of the tank, the second point, when the embryos are simply placed on the leaves, the embryos are easy to slide off and fall, which makes the stability of the placement not very good
