Description
Technical field
The utility model relates to a kind of devices more particularly to a kind of novel embryo vitrifying freeze to carry bar, belong to biological doctor
Field.
Background technique
Embryo cryopreservation is that Issues of Human Assisted Reproductive Technologies is one of the important technical that patient saves embryo, it can effectively be mentioned
High each accumulation pregnancy rate for taking the ovum period.Vitrification can effectively reduce cell freezing damage, improve embryo or
Survival rate and Pregnancy Success rate after egg freezing recovery.It is a kind of current assisted reproductive technology field commonly fast freezing embryo
The method of tire or ovum.But in the laboratory of different Reproductive Medicine Centers, the Freezing-thawing effect of embryo is not quite similar,
It is related bar may to be carried to the freezing that different laboratories uses.Existing most domestic reproductive center mainly carries bar, half using open
Three kinds of glass freezings of closed and closed commercialization carry bar.It is semiclosed be first intrusion liquid nitrogen it is re-closed, open loads bar with
Semi-enclosed load bar contact embryo directly with liquid nitrogen, it is thus possible to so that embryo is there is safety hidden
Suffer from.For human reproduction center, the safety of embryo is extremely important, it is understood that there may be the cross contamination between embryo, or by
In liquid nitrogen, there are embryos caused by microbial contamination to pollute, and therefore, closed freezing carrier uses particularly necessary.
However existing closed carrier structure multiplicity, complicated for operation, price is significantly higher than semi-enclosed load bar and opening
Carry bar.Therefore, easy to operate, cheap vitrified frozen vector is the product that embryo experiments room is badly in need of.
Utility model content
Technical problem to be solved in the utility model is that the defect of the prior art is overcome to provide a kind of novel closed-type glass
Glassization freezing carries bar.The novel closed-type glass freezing carries survival of the bar after guaranteeing embryo's safety, embryo cryopreservation recovery
While rate and Pregnancy Success rate, cost can be reduced, simplifies operation.Feeding device, the feeding device have the at low cost, service life
High, manufacture is easy, is conducive to the advantages that various materials alternating is filling.
Technical problem described in the utility model is realized by the following technical solutions.
A kind of novel closed-type glass freezing described in the utility model carries bar, including outer tube, embryo place pipe, isolation
Pipe, metal column；The metal column is placed in the outer tube bottom；The isolated tube is placed in metal column upper layer；The embryo is put
It sets pipe and is placed in isolated tube upper layer, embryo places tube top end away from outer tube nozzle 1.3cm, and nozzle is sealed.
Preferably, a kind of above-mentioned novel closed-type glass freezing carries bar, and the outer tube is open type glassization freezing
Bar is carried, the length is 13.2cm, diameter 0.3cm；The metal column is stainless steel metal column, and the length is 1.5cm, diameter is
0.2cm；The embryo place pipe diameter be 0.2cm, length 6.6cm, it is that embryo places end, the embryo that embryo, which places pipe one end,
Placing end is that embryo places groove；The embryo places groove and places the angle that pipe one end one length of beveling is 2cm by embryo
It is formed；The isolated tube is intermediate closed pipe, and the length is 2cm, intermediate confining bed length is 1.4cm.
Further, above-mentioned novel closed-type glass freezing carries bar, and the embryo places groove for placing embryo.Embryo
Tire places pipe and is greater than 180 ° in the angle that embryo places the nozzle cross section at end, that is to say, that the part chamfer is put in embryo
The angle shown on the nozzle cross section at end is set less than 180 °, if embryo can occur after angle is excessive places end insertion isolated tube
It is interior, cause embryo damage.The metal column carries bar lower end gravity for increasing novel closed-type glass freezing, can make novel sealing
Enclosed glass freezing carries bar and is immersed in liquid nitrogen perpendicular to embryo's long-time in liquid nitrogen, is conducive to, and is conducive to embryo for a long time
It saves.
Novel closed-type glass freezing described in the utility model carries bar, can avoid in liquid nitrogen that there may be microorganism dirts
Cross contamination between the pollution of embryo caused by contaminating or embryo, and this is simple using novel manufacture craft, it is low in cost.In embryo
When tire freezen protective, may make embryo's vertical immersion in liquid nitrogen, with liquid nitrogen fluid change can occur accordingly sink or on
It rises, embryo will not be caused to damage since liquid nitrogen is reduced.
Detailed description of the invention
Fig. 1 novel closed-type glass freezing described in the utility model carries the schematic diagram of bar
Fig. 2 novel closed-type glass freezing described in the utility model carries the cross that embryo in bar places embryo's placement end of pipe
Schematic cross-section.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1 and Figure 2, respectively marked as the freezing closing of 1. new-type of vetrifying carries bar in figure；2. outer tube；3. embryo is put
