A device for thawing frozen egg cells

Abstract

The invention discloses a thawing device for frozen egg cells, which includes a liquid nitrogen tank, a vacuum heating sleeve, a hydraulic system, an eddy current lifting device, and a control electric box. The vacuum heating sleeve includes a vacuum sleeve and a heating resistance ring. The heating resistance ring is set in the vacuum sleeve. The hydraulic system includes a hydraulic cylinder, a hydraulic pump, a hydraulic motor and a hydraulic oil tank. The hydraulic pump is arranged at one end of the hydraulic motor, and a cover plate is arranged at one end of the hydraulic cylinder. The hydraulic cylinder is provided with a hydraulic rod, and one end of the hydraulic rod is covered with a thrust rod group. In the present invention, the electromagnetic plate is energized to generate magnetism and attract the permanent magnetic plate, the egg cell vessel moves downward, the valve is pushed to compress the air in the compression sleeve, the valve plate in the water supply chamber pushes the water to penetrate the water seepage plate, and the water begins to pass through the water seepage layer to the egg cell Replenishing water, the entire control process is fully automated, no need for grading control to improve the grading quality of egg cells after thawing.

Description

technical field [0001] The invention relates to the technical field of egg cell thawing, in particular to a thawing device for frozen egg cells. Background technique [0002] At present, the freezing and thawing treatment of egg cells is a very strict medical process. It not only serves the purpose of freezing eggs, but also has the characteristics of thawing eggs to wake up eggs and ensure the quality of eggs. However, the treatment of egg cell thawing process is currently still Not too mature, usually the level of egg cells will decrease after awakening, thereby reducing the probability of successful conception. The current thawing device has the following defects: 1. When extracting egg cells in liquid nitrogen freezing, usually directly unscrew the cover and use manual extraction. Since the temperature of liquid nitrogen is -196°, it is easy to cause frostbite to the extractor. 2. After the egg cells are extracted, they are usually placed in a special heating and heat pr...

[0002] At present, the freezing and thawing treatment of egg cells is a very strict medical process. It not only serves the purpose of freezing eggs, but also has the characteristics of thawing eggs to wake up eggs and ensure the quality of eggs. However, the treatment of egg cell thawing process is currently still Not too mature, usually the level of egg cells will decrease after awakening, thereby reducing the probability of successful conception. The current thawing device has the following defects: 1. When extracting egg cells in liquid nitrogen freezing, usually directly unscrew the cover and use manual extraction. Since the temperature of liquid nitrogen is -196°, it is easy to cause frostbite to the extractor. 2. After the egg cells are extracted, they are usually placed in a special heating and heat preservation device. In this way, an independent heating device is required, and the operation process is interrupted. The level after awakening, 3. Since the egg cells will be dehydrated by adding antifreeze when they are frozen, the egg cells need to be replenished with water and antifreeze when thawing. During the process of replenishing water, the antifreeze cannot be discharged in time, which will also affect the awakening of the egg cells. level, so the present invention provides a thawing device for frozen egg cells
