Novel low-temperature preservation device for reproductive medicine

Abstract

The invention discloses a novel low-temperature preservation device for reproductive medicine. The device comprises a refrigeration tank and a tank cover; the tank cover is matched with the refrigeration tank; liquid nitrogen is arranged in refrigeration tank; the inner bottom wall of the refrigeration tank is fixedly connected with a fixing plate; a guide rod is fixedly connected to the left sideof the top of the fixing plate; a left sliding plate is slidably connected to a guide rod; a screw rod is rotatably connected to the right side of the top of the fixing plate; a right sliding plate is screwed to the screw rod; a test tube placement rack is arranged between the left sliding plate and the right sliding plate; a control assembly is arranged at the top of the fixing plate; and a damping moving assembly is arranged at the bottom of the refrigeration tank. The test tube placement rack is adopted, so that a plurality of specimens can be simultaneously stored; the position of the test tube placement rack can be adjusted by rotating the screw rod, so that the specimens are very convenient to place and take; whether the specimens are located on the lower portion in the refrigeration tank or not can be known through the control assembly, so that the preservation effect of the specimens is good; the damping moving assembly is arranged, a damping effect can be achieved when the device moves, and so that the test tubes storing the specimens are prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of reproductive medicine, in particular to a novel cryopreservation device for reproductive medicine. Background technique [0002] Reproductive medicine is a discipline that mainly provides scientific guidance for male and female reproductive medicine clinical, reproductive physiology, fertility regulation and prevention and treatment of reproductive diseases, introduces research results, promotes new technologies, and promotes academic exchanges at home and abroad and research in the field of reproductive medicine. subject development. [0003] Reproductive medicine preservation is often used to store sperm, egg and embryo samples in liquid nitrogen to ensure activity. In the prior art, sperm, egg and embryo samples are generally placed in test tubes, and then the test tubes are stored in liquid nitrogen.

Problems solved by technology

[0003] Reproductive medicine preservation is often used to store sperm, egg and embryo samples in liquid nitrogen to ensure activity. In the prior art, sperm, egg and embryo samples are generally placed in test tubes, and then the test tubes are stored in liquid nitrogen. In nitrogen, when the specimen is preserved, if the specimen is placed in the lower part of the liquid nitrogen tank, it is very inconvenient to place and take the specimen. If the specimen is preserved in the upper part of the liquid nitrogen tank, although the Henaqu The specimens are relatively convenient, but after a period of storage, due to the volatilization of liquid nitrogen, the specimens may not be completely immersed in liquid nitrogen, resulting in damage to the specimens, and the preservation of the specimens is inconvenient
