Problems solved by technology

[0003] In vitro maturation of oocytes is an important reproductive biotechnology, but because oocytes do not experience the growth process before the start of the luteinizing hormone (LH) peak in vivo and biological events interfere with cytoplasmic maturation, resulting in in vitro developmental ability is lower than in vivo mature oocyte

Embodiment 1

[0025] see Figure 1~4 , in an embodiment of the present invention, an oocyte transport device includes a base 1, a storage box 2 and a test tube holder 7; the storage box 2 is fixedly installed on the base 1, the storage box 2 is a circular platform structure, and the storage box 2. A number of test tube holders 7 are evenly installed on the inner circumference for placing oocyte test tubes to be transported; a liquid storage chamber 3 is opened in the middle of the storage box 2, and a storage cover is hingedly installed on the storage chamber 3 10, the interior of the liquid storage chamber 3 is placed with a heat preservation solution for constant temperature storage of oocytes. In this embodiment, the heat preservation solution is an aqueous solution at room temperature, and a circulation pump 5 is fixedly installed on the outside of the liquid storage chamber 3. The circulation pump The output end of 5 communicates with a plurality of circulation pipes 6 through the mult...

Abstract

The invention relates to the technical field of oocyte transportation, and in particular, relates to an oocyte transportation device which comprises a base, a storage box and test tube holders; the storage box is fixedly arranged on the base and is of a circular truncated cone structure, and a plurality of test tube holders are evenly arranged on the peripheral side of the interior of the storagebox; a liquid storage cavity is formed in the middle of the storage box; a storage cover is hinged to the liquid storage cavity; a heat preservation solution for constant-temperature storage of oocytes is placed in the liquid storage cavity, a circulating pump is fixedly arranged on the outer side of the liquid storage cavity, the output end of the circulating pump communicates with a plurality ofcirculating pipes through a multi-way pipe, the circulating pipes are in one-to-one correspondence with the test tube holders, and the other ends of the circulating pipes communicate with the corresponding test tube holders. The plurality of test tube holders are uniformly mounted on the peripheral side in the storage box, and the heat preservation solution in the liquid storage cavity is continuously introduced into the test tube holders by utilizing the circulating pump, so that the temperature of the test tubes in which the oocytes are stored is kept constant.

Description

technical field [0001] The invention relates to the technical field of oocyte transportation, in particular to an oocyte transportation device. Background technique [0002] With the in-depth research and commercial application of embryo engineering technology, the demand for improved female oocytes is increasing day by day. Therefore, improving the maturation rate and quality of oocytes is the focus of current discussion. The transportation time and mode of transportation for collecting oocytes, the time and temperature of in vitro maturation, and the required culture conditions are the key factors for the success of in vitro maturation of oocytes and the success of in vitro fertilization technology. [0003] In vitro maturation of oocytes is an important reproductive biotechnology, but because oocytes do not experience the growth process before the start of the luteinizing hormone (LH) peak in vivo and biological events interfere with cytoplasmic maturation, resulting in ...
