Problems solved by technology

[0004] At present, in the process of thawing embryos, it often occurs that the embryos stick to the carrier rod and are not easy to fall off. Due to the strict thawing time limit, they have to be removed with the help of other tools. At this time, it is very likely that the The embryos are damaged, and even the embryos fall off from the zona pellucida; the carrier on the original carrier rod is a glass slide, and the embryos will be spherical during use, which is not conducive to absorbing the freezing liquid around the embryos. It takes a long time and is likely to affect the quality of the embryo

Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] Such as Figure 1 to Figure 3 As shown, a frozen load rod provided by the embodiment of the present invention includes a load rod and a sleeve 20; The bearing area 121, the bearing area 121 is preferably arranged on the front end side of the glass slide 12; one end of the sleeve 20 is open and the other end is closed, and the open end of the sleeve 20 is used to be sleeved on the front end of the handle 11 so that the slide 12 is closed in the Inside the sleeve 20. Thus, by setting the grid-shaped bearing area 121 on the glass slide 12 for bearing the gamete / embryo droplet, when the gamete or embryo droplet drops in the grid-like bearing area 121, the gamete / embryo can It is stably adsorbed on the carrying area 121, which improves the adsor...

Abstract

The invention relates to the technical field of medical instruments, in particular to a freezing carrier rod. The device comprises a carrying rod and a sleeve, wherein the carrying rod comprises a handle and a glass slide arranged at the front end of the handle, and a latticed carrying area is formed in the glass slide. One end of the sleeve is open and the other end is closed, and the open end ofthe sleeve sleeves the front end of the handle. The latticed bearing area is arranged on the slide, so that when gametes or embryo droplets drop in the bearing area, the gametes / embryos can be stablyadsorbed on the bearing area; therefore, the adsorption performance of the slide is improved, the gametes / embryos droplets can be well fixed during freezing, and the risk that the gametes / embryos droplets drop is avoided; the grid structure can enable the embryo to be in full contact with liquid nitrogen, so that the embryo has a relatively high freezing rate; during thawing, the grid structure can reduce the contact area between gametes / embryos and the surface of the slide, is beneficial to falling of the gametes / embryos, can enable the embryos to be in full contact with thawing liquid, andhas a higher thawing rate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a freezing rod. Background technique [0002] Assisted reproduction is the abbreviation of human assisted reproductive technology, which refers to the technology of using medical assistance to make infertile couples pregnant, including artificial insemination, in vitro fertilization-embryo transfer and its derivative technologies. In in vitro fertilization-embryo transfer technology (also known as test tube baby technology), various assisted reproductive specimens such as sperm and egg in vitro fertilization operations, embryo transfer operations, and embryo freezing and recovery can be checked through a special IVF system check. [0003] The cryopreservation of gametes / embryos provides a wider range of options for infertility patients in the field of assisted reproduction, and it has become one of the indispensable technologies in assisted reproductive technology; and in...
