Freezing pole that carries

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a freezing pole that carries.

Background

Assisted reproduction is a short-term assisted reproduction technology for human beings, and refers to a technology for making sterile couples pregnant by adopting medical auxiliary means, and comprises two major technologies of artificial insemination, in vitro fertilization-embryo transplantation and derivation. In the IVF-embryo transfer technique (also called tube transfer technique), various auxiliary reproductive specimens such as sperm and ovum in vitro fertilization operation, embryo transfer operation, and freezing and recovering work of embryo can be checked by a special IVF system check mode.

The cryopreservation of gametes/embryos in the field of assisted reproduction provides a wider choice for sterile patients, and the cryopreservation of gametes/embryos becomes one of indispensable technologies in assisted reproduction technology; in the process of cryopreservation of gametes/embryos, the gametes/embryos are usually cryopreserved by using a freezing carrying rod as a carrier.

At present, in the process of unfreezing embryos, the phenomenon that the embryos are stuck on a carrying rod and are not easy to fall off often occurs, and the embryos have to be taken down by other tools due to the limitation of strict unfreezing time, so that the embryos are likely to be damaged, and even fall off from a zona pellucida occurs; the carrier on the original carrying rod is a glass slide, the embryo can be in a spherical shape in the using process, the embryo is not beneficial to absorbing the freezing liquid around the embryo, meanwhile, the freezing and the unfreezing both need longer time, and the quality of the embryo is easily influenced.

SUMMERY OF THE UTILITY MODEL

To the deficiencies of the prior art, an object of the present invention is to provide a freezing rod.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

A freezing carrier bar comprises a carrier bar and a sleeve; the slide rod comprises a handle and a slide arranged at the front end of the handle, and a grid-shaped bearing area is formed on the slide; one end of the sleeve is open, the other end of the sleeve is closed, and the open end of the sleeve is sleeved at the front end of the handle.

Preferably, the carrier region is disposed at a front end of the slide.

Preferably, black identification points are arranged at the front end of the slide, and the identification points are distributed on the front side of the bearing area.

Preferably, the front end and the rear end of the handle are respectively provided with a supporting block.

Preferably, the cross section of the supporting block is of a square structure and is formed by extending outwards from the peripheral wall of the handle.

Preferably, the support block is provided with a marking area for writing a mark.

Preferably, the front end of the handle is provided with a connecting section in a cone structure, and the slide is arranged at the front end of the connecting section; the open end of sleeve sets up to the horn structure with linking up section complex, the open end and the linking up section interference fit of sleeve.

Preferably, the closed end of the sleeve is provided with a steel ring.

Due to the adoption of the scheme, the utility model discloses a set up the latticed bearing area on the slide to be used for bearing gamete/embryo liquid drop, when gamete or embryo liquid drop drip in latticed bearing area, gamete/embryo can adsorb on bearing area steadily, has improved the adsorption efficiency of slide, and when freezing, because bearing area surface grid structure, can fix gamete/embryo liquid drop well, avoid gamete/embryo liquid drop risk of dropping; when the gametes/embryos are frozen, gametes or embryo liquid drops are uniformly distributed in the latticed bearing area to provide a larger contact area for the gametes/embryos and liquid nitrogen, and compared with a planar structure, the latticed structure can enable the embryos to be in full contact with the liquid nitrogen, so that the embryos have a higher freezing rate; when the gamete/embryo is unfrozen, the grid structure can reduce the contact area of the gamete/embryo and the surface of the glass slide, and is favorable for the gamete/embryo to fall off.

Based on the structure, the structure is simple and compact, and the grid-shaped bearing area is arranged on the glass slide, so that a larger contact area is provided for the embryo and liquid nitrogen/unfreezing liquid, and the embryo has higher freezing/unfreezing speed; meanwhile, the contact area between the embryo and the glass slide is reduced, and the embryo can fall off from the freezing carrying rod quickly, so that the method has strong practical value and market popularization value.
