Problems solved by technology

[0003] The problem existing when applying the above-mentioned carrier device is: the hand-held part of the existing frozen loading rod is relatively long, generally about 12 cm. Store in liquid nitrogen at a temperature of -196 degrees
However, due to the long hand-held part of the freezing rod, rest assured that the liquid nitrogen takes up more space, which will cause waste of liquid nitrogen tanks and liquid nitrogen, and increase the cost of freezing oocytes or embryos.

Embodiment 1

[0020] Example 1: A scalable and efficient oocyte / embryo freezing rod, such as Figure 1-Figure 3 As shown, it includes a load rod part and a load rod outer sleeve. The load rod part is composed of a hand-held rod 2 and a freezing blade 1. The handle rod is a telescopic rod, and the telescopic rod is composed of 4 hollow rods with different diameters. Tube set, the hollow tube is divided into a large end tube 21, a middle tube assembly 22 and a small end tube 23 which are sequentially socketed, and the middle tube assembly is two middle tubes 221 with different diameters Sleeve joint structure, one end of the large end tube is set as a tapered mouth 24 with gradually smaller diameter, the other end is connected with the freezing blade 1, one end of the middle tube is set as a tapered mouth with a gradually smaller diameter, and the other end is provided with an anti-dropping 25, the middle pipe with a larger diameter is set in the large end pipe 21, the anti-off protrusion 25 ...

Embodiment 2

[0023] Embodiment 2: A scalable high-efficiency oocyte / embryo freezing carrier, such as Figure 4-Figure 5 As shown, it includes a loading rod part and a loading rod outer sleeve. The loading rod part is composed of a hand-held rod 2 and a freezing blade 1. The described hand-held rod is a telescopic rod, and the telescopic rod is composed of 4 hollow rods with different diameters. The hollow tube is composed of a pipe set, and the hollow pipe is divided into a large-end internally threaded pipe 26, a middle internally and externally threaded pipe assembly 27, and a small-end externally threaded pipe 28, which are sequentially threaded. The middle internally and externally threaded pipe assembly is 2 The middle inner and outer threaded pipes 271 with different diameters are socketed, the middle inner and outer threaded pipe with a larger diameter is sleeved in the large end inner threaded pipe 26, the middle inner and outer threaded pipe with a smaller diameter is sleeved in th...

Abstract

The invention relates to a telescopic efficient oocyte/embryo freezing carrying rod. The telescopic efficient oocyte/embryo freezing carrying rod comprises a carrying rod part and a carrying rod sleeve pipe; the carrying rod part consists of a handheld rod and a freezing blade; the handheld rod is a telescopic rod; the telescopic rod consists of 2 to 8 hollow pipes with different diameter in a sleeving way; and one end of the telescopic rod is fixedly connected with the freezing blade. A cold tool has the following advantages: 1, the handheld part of the carrying rod adopts a telescopic rod structure, the step of putting the freezing carrying rod into a freezing bracket by hands can be guaranteed, the handheld part is long enough and convenient to operate, the handheld part is shortened toone third or one fourth of the original freezing carrying rod after the freezing carrying rod is put into the freezing bracket, one bracket can store the freezing carrying rods with the number whichis three times or more times that of the original number, and the utilization efficiency of a freezing tank can be increased by about three times; and 2, the expenditure of buying a liquid nitrogen tank and liquid nitrogen can be greatly saved and the freezing cost of the oocyte/embryo is reduced.

Description

technical field [0001] The invention relates to a freezing rod, in particular to a retractable high-efficiency oocyte / embryo freezing rod. Background technique [0002] The existing vitrification loading rod is usually composed of a flat front-end freezing blade and a hand-held part made of polymer materials. During use, oocytes or embryos are placed on the blade for cryopreservation, and it is also convenient Thaw and recover when needed in the future. 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 into the freezer again. stored in liquid. [0003] The problem existing when applying the above-mentioned carrier device is: the hand-held part of the existing frozen loading rod is relatively long, generally about 12 cm. Store in liquid nitrogen at a temperature of -196 degrees. However, due to the long hand-held part of the free...
