Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thin tube frozen semen storage technology, specifically relating to a device for dispensing thin tube frozen semen into a thumb tube. Background Technology
[0002] Artificial insemination is an important measure for the development of animal husbandry in my country. Currently, most of the semen used for artificial insemination in my country is frozen semen in capillary tubes. The use of frozen semen in capillary tubes improves the utilization rate of superior breeding males, accelerates breed improvement, enhances production performance, and is not limited by region or time, significantly reducing the number of breeding males and saving costs. Frozen semen cannot be stored without a cold source and must be stored below the critical temperature range for sperm freezing. Because the temperature of liquid nitrogen is much lower than the critical temperature range for sperm freezing, it is convenient to use and provides reliable preservation of frozen semen, and therefore has been widely adopted. Frozen semen can be preserved for a long time in liquid nitrogen without a decrease in sperm motility. When storing frozen semen in liquid nitrogen, the capillary tubes of frozen semen need to be dispensed into thumb tubes first. The traditional method of filling the tubes involves placing each capillary tube of frozen semen into a thumb tube removed from the liquid nitrogen, which is inefficient, time-consuming, and the rapid temperature rise after removal from the liquid nitrogen can cause a decrease in sperm motility, reducing the quality of the frozen semen. Summary of the Invention
[0003] To overcome the problems of inefficiency and time-consuming traditional methods of filling thin tubes of frozen semen into thumb tubes after they have left liquid nitrogen, which involve placing each tube individually into a thumb tube, and the rapid temperature rise after leaving liquid nitrogen can reduce the viability and quality of the frozen semen, this invention provides a device for dispensing thin tubes of frozen semen into thumb tubes. The device has a simple structure, low cost, and is easy to manufacture. The sleeve 41 is connected to the thumb tube 2. The thumb tube is first inserted into liquid nitrogen, supported by the base 4 at the opening of the freezing tank 3. Then, thin tubes of frozen semen are dispensed into the thumb tubes inserted into the liquid nitrogen. After dispensing one thumb tube 2, pressing the inlet cylinder 1 compresses the return spring 5, and the bottom of the outlet 11 pushes the top of the thumb tube 2, thus placing the thumb tube 2 into the freezing tank 3. This method enables rapid dispensing of thin tubes of frozen semen into thumb tubes, effectively shortening the time the frozen semen has been out of liquid nitrogen, improving the quality of the frozen semen, and increasing work efficiency. This is of great significance in the field of artificial insemination technology.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A device for dispensing frozen semen into a thumb tube mainly includes an inlet cylinder 1, a base 4, and a return spring 5. The base 4 has a through sleeve 41 in the middle, and the bottom of the sleeve 41 has a connecting section 42 that connects with the thumb tube 2. The inlet cylinder 1 is funnel-shaped, and the discharge port 11 at the bottom of the inlet cylinder 1 is movably inserted into the sleeve 41. The return spring 5 is fitted on the discharge port 11, and the two ends of the return spring 5 are respectively supported and limited at the bottom of the inlet cylinder 1 and the top of the base 4. The base 4 is larger than the opening of the freezing barrel 3.
[0005] Furthermore, the inner wall of the connecting section 42 is provided with a rubber sleeve 12 to increase the frictional force between the connecting section and the thumb tube 2.
[0006] Furthermore, the base 4 is provided with an operating handle 43.
[0007] Furthermore, the bottom of the base 4 is provided with a groove 44 that fits and limits the opening of the freezing drum 3.
[0008] Furthermore, the center of the base 4 is concave.
[0009] The beneficial effects of this utility model are:
[0010] This invention features a simple structure, low cost, and ease of production. The sleeve is connected to the thumb tube. The thumb tube is first inserted into liquid nitrogen, with the base supported on the opening of the freezing tank. Then, thin tubes of frozen semen are dispensed and placed into the thumb tube immersed in liquid nitrogen. After dispensing one thumb tube, pressing the inlet cylinder compresses the return spring, pushing the top of the thumb tube from the bottom of the outlet tube, thus placing the thumb tube into the freezing tank. This allows for rapid dispensing of thin tubes of frozen semen into the thumb tube, effectively shortening the time the semen is out of liquid nitrogen, improving semen quality, and increasing work efficiency. It is of great significance in the field of artificial insemination technology. Attached Figure Description

It is easy to manufacture; the sleeve 41 is connected to the thumb tube 2, the thumb tube is first inserted into liquid nitrogen, the base 4 is supported on the mouth of the freezing tank 3, and then the thin tube of frozen semen is taken and dispensed into the thumb tube inserted into the liquid nitrogen. After the dispensing of one thumb tube 2 is completed, the bottom of the discharge port 11 pushes the top of the thumb tube 2 by pressing the inlet tube 1, so that the thumb tube 2 is put into the freezing tank 3.
