Automatic sperm cold storage table and controller

Abstract

The invention discloses an automatic sperm cold storage table and controller, which comprises a bottom plate, wherein a guide rail is arranged on the bottom plate; an object carrying table is arrangedon the guide rail and is connected with a power mechanism driving the object carrying table to move along the guide rail; the power mechanism is connected with a controller, and comprises a motor anda screw; the object carrying table is provided with a threaded hole; the lower end of the threaded hole is movably connected with the bottom plate; the motor is arranged at the lower side of the bottom plate; the screw rod is connected with the threaded hole through screw threads; a control base is arranged at the lower side of the bottom plate; the controller and the motor are arranged in the control base; after the carrying of a sperm freezing sheet, the object carrying table can automatically and slowly descend into liquid nitrogen; the operation is convenient; the liquid nitrogen suffocation on the sperm freezing sheet clamped by professional medical personnel is not needed; the energy consumption of medical personnel is greatly reduced. In addition, a plurality of sperm freezing sheets can be carried and placed onto the object carrying table; the batched sperm liquid nitrogen suffocation freezing can be performed at the same time; very high cold storage efficiency is realized.

Description

technical field [0001] The invention relates to a medical assisted reproductive equipment, in particular to an automatic sperm refrigerator. Background technique [0002] Sperm cold storage is to store your own sperm in a medical institution with corresponding qualifications to prevent future fertility risks. It can be used as a means of assisted reproduction for infertile people. The treatment of infertility provides strong support and is a very important part of assisted reproduction, but the whole process of sperm refrigeration and preservation requires professional medical staff to operate special equipment to conduct refrigeration experiments on sperm one by one , this cold storage method tests the operation level of the medical staff, and consumes a lot of energy and physical strength of the medical staff. Especially in the process of using liquid nitrogen to fumigate the sperm to cool down, the medical staff need to manually clamp the frozen sperm slices containing sp...

[0002] Sperm cold storage is to store your own sperm in a medical institution with corresponding qualifications to prevent future fertility risks. It can be used as a means of assisted reproduction for infertile people. The treatment of infertility provides strong support and is a very important part of assisted reproduction, but the whole process of sperm refrigeration and preservation requires professional medical staff to operate special equipment to conduct refrigeration experiments on sperm one by one , this cold storage method tests the operation level of the medical staff, and consumes a lot of energy and physical strength of the medical staff. Especially in the process of using liquid nitrogen to fumigate the sperm to cool down, the medical staff need to manually clamp the frozen sperm slices containing sperm and gradually lower the temperature. The height of the frozen sperm slices gradually shortens the distance between the frozen sperm slices and the liquid nitrogen, and gradually realizes the cooling and refrigeration of the sperm. This manual operation is limited by professional skills. If the descending speed is too fast or too slow, the sperm will be lost. activity, while manual operation can only operate one piece of frozen sperm at a time, the efficiency of freezing sperm is extremely low, and it causes waste of liquid nitrogen, which increases the cost of sperm refrigeration
