Abstract
The utility model discloses a carrier device for vitrification freezing of embryo and ovum in auxiliary reproductive technology. The carrier device comprises a small ring, a sliding groove, a small ring support structure, a handle, an outer tube, a protection cap and a mark plug. The carrier device can improve the vitrification speed of embryo and ovum, enhance the survival rate of resuscitation of embryo and ovum, reduce the loss of embryo and ovum due to collision, and obviate misoperation and frostbite of operators.
Description
Technical field
The utility model relates to freezing carrier device, particularly relates to being used for embryo that the artificial culture in vitro of human auxiliary procreation technology obtains or egg mother cell at the carrier arrangement that carries out loading when glass freezing is preserved embryo or ovum.
Background technology
In artificial supplementary reproduction treatment, under the effect of promoting ovulation drug, can get access to a plurality of ovums at present, after in vitro fertilization, can obtain a plurality of embryos, but when the embryo implants, can only implant 1-3 embryo.Be the reason of prevent to become pregnant failure or other demand, remaining embryo quality or egg freezing are preserved, can frozen embryo or ovum be thawed, transplant or be fertilized, improved the utilization rate of embryo and ovum at next cycle.The embryo is frozen in subzero 196 ℃ temperature, and stasi can be preserved the several years.
The glass freezing technology is the method for a kind of snap frozen embryo or ovum, is subjected to extensive concern along with the development of auxiliary procreation technology.This technology have chilling rate fast, avoid ice crystal to form, reduce freezing-thawing damage and simple operation and other advantages.By clinical observation, confirm survival rate and pregnant success rate after this method can improve embryo or egg freezing recovery.
When embryo or ovum carry out glass freezing, in order to prevent losing, damage or obscuring of embryo or ovum, generally all be placed on each embryo or ovum in carrier arrangement or the container separately, if any be placed on seal in the tiny straw freezing, but these carriers are freezing and all operate when thawing complicated, and freezing rate is slow, and the freezing anabiosis rate of embryo or ovum is low, influences the survival rate of embryo or ovum.
Existing carrier arrangement has two kinds, it is a kind of that to be the front end made by macromolecular material collude or front end is freezing " shovel " of flat sheet for " J " type freezing, another kind is to have one by terylene or nylon yarn or thread small circle ring by the front end that metal tube constitutes, when using these two kinds of carrier arrangements, in the process of using be egg mother cell or embryo are placed on collude, the position of " shovel " or ring carries out freezing preservation, the while recovery of thawing when needing after also being convenient to.Above-mentioned carrier arrangement is to finish under the supervision of normal eyesight; to have the colluding of cell or embryo, " shovel " or ring and carry out snap frozen with glass freezing liquid or liquid nitrogen; and outside it, put plastic tube or the little plastic bottle protection of packing into, afterwards, put in the freezing liquid once more and preserve.The problem that exists when using above-mentioned carrier arrangement is: collude, the handle of " shovel " or ring is longer, in addition, liquid nitrogen is vaporized in air, produce mist, when requiring quick encased pipe, inconvenient operation, the time that needs is longer, freezingly collude, the front end of " shovel " or ring touched easily, lose thereby the embryo that freezes or ovum are come off; When using above-mentioned carrier arrangement, if handle is shortened because collude, " shovel " or to encircle the front end temperature very low, the operator is not easy to hand-held and observation.
The utility model content
That the purpose of this utility model is to provide is a kind of simple in structure, easy to operate, embryo and ovum freezing carrier device for vitrifying in the auxiliary procreation technology efficiently.
The technical scheme of embryo and ovum freezing carrier device for vitrifying is in the utility model auxiliary procreation technology:
Embryo and ovum freezing carrier device for vitrifying are made up of supporting construction, handle, outer tube, protective cap and the mark plug of small circle ring, sliding tray, small circle ring in the utility model auxiliary procreation technology; Wherein, described small circle ring is made by nonpoisonous and tasteless materials such as polypropylene composite fibre, dacron thread, nylon or wires; The supporting construction of described small circle ring is tubulose or the list structure of being made by metal or macromolecular material, the fixedly connected described small circle ring of one end, the fixedly connected described handle of the other end; Described sliding tray is the slit that is positioned at the described outer tube outside; The part of described handle places outer tube, and the other part of described handle is stretched out from described sliding tray; The internal diameter of described protective cap is slightly larger than the external diameter of described outer tube; The external diameter of described mark plug is slightly less than the internal diameter of described outer tube, and places the tail end of described outer tube.Under external force, described handle slides in sliding tray, and the supporting construction of drive small circle ring is slided in outer tube together.When described handle utilizes sliding tray to front slide, the supporting construction of described small circle ring and described small circle ring under the drive of described handle in outer tube to front slide, slide to outside the outer tube, at this moment, embryo or ovum can be contained on the small circle ring, or take off from small circle ring; When described handle utilizes sliding tray to slide backward; same supporting construction and the described small circle ring that drives described small circle ring slides in outer tube; the supporting construction of described small circle ring and described small circle ring slide in the outer tube; at this moment; outside at outer tube can put protective cap; the small circle ring that has loaded embryo or cell is protected; embryo and ovum freezing carrier device for vitrifying drop in the liquid nitrogen fast in the auxiliary procreation technology of embryo or ovum with being equipped with, and can carry out freezing to it.
Embryo and ovum freezing carrier device for vitrifying embryos frozen or ovum size, frozen embryo or the diameter of the described small circle ring of ovum quantity regulating and the thickness of material as required in the utility model auxiliary procreation technology makes embryo or cell be convenient to load.
The embryo can be alternative with the hook arrangement or the laminated structure of different sizes with the small circle ring in the ovum freezing carrier device for vitrifying in the utility model auxiliary procreation technology.
Placing the mark plug of the tail end of the utility model auxiliary procreation technology embryo and ovum freezing carrier device for vitrifying outer tube can be different colours, so that distinguished in use.
Embryo and ovum freezing carrier device for vitrifying beneficial effect are in the utility model auxiliary procreation technology: the freezing rate that can improve embryo and ovum, improve embryo and the ovum recovery survival rate of thawing, reduce embryo and ovum and lose, reduce operating personnel's error and frostbite because of collision.
