Automatic animal genetic material tubing equipment

Abstract

The invention discloses animal genetic material automatic tubulation equipment which comprises a straw storage assembly, a straw feeding assembly, a straw feeding assembly, a straw feeding assembly, a straw feeding assembly and a straw discharging assembly which are all mounted on a main machine box, and a plurality of straws are positioned on the straw storage assembly; the heat sealing assembly comprises a heating block used for sealing the straw; the discharging and collecting assembly comprises a discharging mechanism and a finished product collecting barrel, and the movable liquid suction assembly comprises a liquid suction mechanism and a driving mechanism; the driving mechanism drives the liquid suction mechanism to move, the straw is inserted and positioned in the liquid suction end by the liquid suction mechanism, the straw is driven by the liquid suction mechanism to sequentially suck an HTF solution and animal genetic materials through negative pressure, the opening end of the straw is sealed through the heating block, the straw subjected to heat sealing is clamped by the discharging mechanism and is pulled away from the liquid suction mechanism, and the HTF solution and the animal genetic materials are discharged through the discharging mechanism. The discharging mechanism relieves clamping of the straw, and the straw containing the animal genetic materials automatically falls into the finished product collecting barrel. According to the straw tubulation device, the tubulation efficiency is high, and the liquid suction amount in each straw can be kept high in consistency.

[0002] Reproductive engineering is the use of biomedical technology to intervene in the reproductive process. It is a systematic engineering aimed at reducing fetal genetic and immune defects and solving infertility. In reproductive engineering research, animals are usually used as research objects, but in the process of research experiments, It is often necessary to prepare or import genetically modified animals from abroad, but the preparation or import of animals is technically difficult, expensive, and the number of animals obtained is limited, and the number of animals used for scientific experiments needs to reach a certain statistical significance. However, the cycle of natural reproduction is relatively long, but the method of sperm cryopreservation and multiple in vitro fertilization can quickly obtain a sufficient number of animals for scientific experimental research; therefore, the use of sperm cryopreservation can save resources In order to quickly obtain a large number of animals; however, in the process of animal sperm freezing, the washed animal sperm is generally put into a straw manually, and then put into a liquid nitrogen tank after steps such as hot pressing, shearing and packaging , this method is not only inefficient but also increases the cost of the experimental operation, and at the same time increases the experimental steps and the space occupied by the equipment, which causes inconvenience to the experimenters. The most important thing is that the packaging of animal sperm is mainly done by the operator. The solution is manually divided into multiple parts, and each time the straw is used manually to absorb liquid, it is very easy to cause uneven liquid absorption, which will affect the later experimental research; therefore, an effective solution to the above problems is urgently needed
