A kind of drying box for cattle and sheep sperm

Abstract

The invention discloses a cattle and sheep sperm drying box, which comprises a box body and a door panel arranged on the box body, one end of the door panel is movably connected to the side wall of the box body, and a first A chute, the first chute is pierced with a first loading plate, the first loading plate is provided with a plurality of second loading plates, and the second loading plate is provided with glass slides , the top of the box body is provided with a first gas storage box and a second gas storage box, the first gas storage box and the second gas storage box are connected through a connecting pipe, and a driving motor is arranged in the connecting pipe, The output shaft of the driving motor is provided with a plurality of fan blades, the second air storage box is provided with a heating block, and the first air storage box and the second air storage box are respectively communicated with the box body; Through the recycling of nitrogen, there is no need to refill nitrogen after filling nitrogen once, which reduces the loss of nitrogen and avoids excessive nitrogen being discharged into the air to cause harm to the staff.

Description

technical field [0001] The invention belongs to the technical field of biological cell preservation, in particular to a drying box for bovine and sheep sperm. Background technique [0002] The routine preservation of sperm mainly includes cryopreservation and room temperature preservation. Conventional cryopreservation techniques require liquid nitrogen or dry ice. Among them, liquid nitrogen not only requires special steel tanks, but also is dangerous, which brings great inconvenience to transportation; while dry ice is easy to melt at room temperature, which has limitations such as inconvenient transportation, high storage costs, and short storage time. [0003] Since the introduction of intracytoplasmic sperm injection (ICSI), many simpler methods of semen preservation have been investigated, including freeze-drying and evaporative drying. After drying, semen can not only be stored at 4°C for a long time, but also can be transported and stored for a short time at room te...

AI Technical Summary

Problems solved by technology

The use of nitrogen in this method requires the use of special nitrogen cylinders, and during the purging process, the loss of nitrogen is serious, the cost is high, the operation is complicated, and there is great danger in the operation process.

However, the method of evaporative drying in a natural environment has low drying efficiency, and with the increase of drying time, the integrity rate of semen chromosomes will be greatly affected
