Abstract

The invention discloses a normal-temperature oocyte preservation device. The invention relates to the technical field of oocyte preservation. The problem that in the prior art, an oocyte preservationdevice is prone to damaging oocytes is solved. Technical key points are that: the preservation device comprises a box body, wherein the box body is divided into a lower box body and an upper box body;the lower box body is hermetically connected with the upper box body; a placing groove is formed in the lower box body; the placing groove is connected with a micro-flow pump and a nutrient solutioncollecting groove through a circulating pipe; the micro-flow pump is communicated with a fluid storage box; the micro-flow pump is used for conveying oocyte preserving fluid in the fluid storage box to the placing groove through the circulating pipe and keeping the oocyte preserving fluid in the placing groove flowing; an oocyte preservation tube is arranged in the placing groove, permeation holesare further formed in the surface of the oocyte preservation tube, multiple groups of oocyte preservation tubes are arranged, and an oocyte is placed in each oocyte preservation tube; according to the invention, the oocytes are prevented from being damaged in the preservation process.

Description

technical field [0001] The invention relates to the technical field of oocyte preservation, in particular to an oocyte preservation device at room temperature. Background technique [0002] In the prior art, cryopreservation is mainly used for the preservation of oocytes, specifically, the oocytes are carried on a special freezing carrier for preservation. However, with the prior art, the devices for storing oocytes have high requirements, and the materials of these devices must be resistant to low temperature and cannot affect the oocytes, so the cost of materials is high. [0003] Chinese Patent Publication No. "CN205106147U" discloses a pig oocyte storage device at room temperature, including: a glass tube, a glass cover, a pig oocyte storage plate and a light shield; the glass tube and the glass cover are sealed and connected; the pig egg The mother cell storage plate is fixedly installed inside the glass tube, and the pig oocyte storage plate is provided with a concave...
