Abstract
The utility model provides a fine straw for carrying out vitrification on an embryo. Straw plugs are arranged at the two ends of the straw, wherein one straw plug is provided with a sheet-shaped expanded part on which embryo information is written. The outer diameter of the straw is less than or equal to 1mm and the inner diameter of the straw is less than or equal to 0.5mm. The straw is small in diameter and thin in wall, so that liquid in a straw cavity is less; and when the embryo freezing fine straw is added into liquid nitrogen, vitrification liquid in the straw can be rapidly cooled and reaches a vitrification state rapidly. As being tightly closed in the straw, the embryo is prevented from being polluted in a freezing and storing process.
Description
Technical field
The utility model relates to a kind of straw for frozen embryo.
Background technology
At present, the frozen embryo carrier mainly contains two kinds, a kind ofly is one and is the plastics straw of tampon that two kinds of specifications of 0.25ml and 0.5ml are arranged, and is a kind of for being specifically designed to the bar that carries of embryo vitrifying freeze.The former is applicable to the embryo, and sequencing is freezing at a slow speed, and the latter is applicable to the embryo vitrifying snap frozen.In recent years, most of supplementary reproduction mechanism adopts glass freezing.Concrete grammar is that the micro liquid that will contain the embryo with capillary is transferred to the ad-hoc location that glass freezing carries bar, glass freezing is carried bar again and inserts in the straw, drops into freezing preservation in the liquid nitrogen at last.This process needs the embryo is carried bar with capillary transfer to glass freezing, the embryo might be lost in shifting embryo's process.
Summary of the invention
In order to overcome the deficiency that existing embryo cryopreservation straw and embryo vitrifying freeze carry bar, the utility model provides a kind of embryo cryopreservation straw.
The technical scheme that its technical problem that solves the utility model adopts is;
A kind of embryo cryopreservation straw comprises a straw, and the straw two ends are connected with the straw plug, and the straw of any end has sheet beyond the Great Wall and expands portion, and straw adopts the good transparent plastic of heat conductivility to make, and the sheet portion of expanding is used for writing embryo's information in the straw in the above.
External diameter≤the 1mm of straw, internal diameter≤0.5mm.
The beneficial effects of the utility model are, because this straw diameter is little, tube wall is thin, and amount of liquid is few in the tube chamber, when thin straw drops in the liquid nitrogen with embryo cryopreservation, can make the very fast cooling of glass freezing liquid in the straw, reach the glass freezing state rapidly.Because the embryo is enclosed within the straw, can avoid that the embryo is polluted in the refrigerated storage process.Traditional glass freezing is the embryo to be transferred to glass freezing carry bar, glass freezing is carried bar again and inserts in the straw.Using the utility model frozen embryo is directly to be pumped in the straw containing embryo's liquid.Not only simplify operation sequence, and can be reduced in the probability of losing the embryo in the transfer process.
Description of drawings
Fig. 1 is the structural representation of embryo cryopreservation straw described in the utility model.
1 is straw among the figure, and 2 is the straw plug.
Embodiment
Below in conjunction with accompanying drawing embryo cryopreservation straw described in the utility model is done and to be specified.
A kind of embryo cryopreservation straw described in the utility model comprises a straw 1, and straw 1 two ends are connected with straw plug 2, and the straw of any end has sheet beyond the Great Wall and expands portion.External diameter≤the 1mm of described straw 1, internal diameter≤0.5mm.
During frozen embryo, connect straw 1 with syringe, will contain embryo cryopreservation liquid and suck straw 1.Behind straw plug 2 sealing one end straw opening, remove syringe, expand the straw plug 2 of portion with the strap shape and seal the other end of straws.Embryo's information in the straw is write by the sheet portion of expanding at straw plug 2, in order to accurately find out the embryo when thawing the embryo.
Claims (2)
1. embryo cryopreservation straw, it is characterized in that: comprise a straw (1), straw (1) two ends are connected with straw plug (2), and the straw of any end has sheet beyond the Great Wall and expands portion.
2. embryo cryopreservation straw according to claim 1 is characterized in that: external diameter≤1mm, the internal diameter≤0.5mm of described straw (1).
