Description
Technical field
The invention belongs to the field of medical instrument technology, more particularly, to a kind of auxiliary device that ovum survival rate can be improved.
Background technique
Treating infertile main method has drug therapy, operative treatment and assisted reproductive therapy, wherein auxiliary life
Growing is that treatment is one of the important means of infertile, has higher pregnancy rate compared to other two kinds for the treatment of methods.Supplementary reproduction skill
The main category of art includes artificial insemination AI and vitro fertilization-embryo implanting IVF-ET and its deriving technology two major classes, clinical number
It shows according to statistics, at least 20% Mr. and Mrs in infertile patients, it is necessary to fertility is just able to achieve by supplementary reproduction.Supplementary reproduction is
The Last Resort of infertile treatment does not obtain effect by conventional medicine and operative treatment, is likely to give birth to by auxiliary
Plantation technology is treated to realize.The assisted reproductive technology in China is very mature at present, and success rate can reach 60% or so, in the whole world
It stands out.
Ovum is taken in reproductive technology and picks up ovum operating process:
1, take ovum: clinician takes out the liquor folliculi containing ovum using ovum system such as Fig. 1 is taken out of her ovaries.Institute
The egg-taking tube road used is up to 110cm, outer diameter 5mm such as Fig. 2.Due to the individual difference of the ovarian follicle quantity of patient, from different patients
For the ovarian follicle liquid pipe number taken out in ovary between 2-10 pipe, every pipe liquor folliculi is about 10ml.According to the skilled journey of clinician
Difference is spent, is 60 seconds/pipe or so the time required to every pipe.Liquor folliculi is directly loadable into test tube, is placed on constant temp test tube rack such as Fig. 3,
Guarantee 37 DEG C of constant temperature.
2, pick up ovum: laboratory embryologist takes off test tube from constant temp test tube rack, gently by invisible spectro liquor folliculi
It pours into the culture dish of 10cm diameter, liquor folliculi will be laid in culture dish surface, and liquid thickness is generally 5mm.Culture dish is put
It is placed on the matched constant temperature objective table of disecting microscope such as Fig. 4, embryologist identifies ovum using 10 times of mirrors, manually controls bar
Single oocyte, is sucked suction pipe by the red rubber part of family name's suction pipe such as Fig. 5, then is moved into the small culture dish of 5cm diameter, Zhu Shouzai
Small culture dish is put into rapidly in the desktop incubator for having set 37 DEG C of constant temperature.This process because of embryologist's proficiency not
Together, at 90 seconds or so the time required to operation.
The technologies such as supplementary reproduction and cell biological engineering, to sperm, ovum, fertilized eggs, body early embryo, culture cell with
And in the treatment process of samples such as in vitro living tissue, the small helminth of work and microorganism, has the characteristics that its is common, that is, leaving work
In the case where body, it is both needed to be placed under microscope and is observed and handled in 35~37 DEG C of certain temperature range, can just make by sample
Product maintain normal physiological activity, so that obtain observation is appropriately determined result.
In the collection and identification process of assisted reproductive technology ovum, embryologist will take the liquor folliculi of ovum personnel collection gently
It pours into 10cm culture dish, liquor folliculi will be laid in culture dish surface, and liquid thickness is generally 5mm.Culture dish is placed in solution
It cuts open on the matched constant temperature objective table of microscope, identifies ovum using 10 times of mirrors.It cannot be covered on liquor folliculi during this operation
Mineral oil can not cover culture ware lid.Liquor folliculi at this time, which is equivalent to, to be exposed in external environment, and environmental factor such as temperature becomes
Change, pH change or light irradiation etc. have damage to ovum, influence the fertility of ovum and the developmental potentiality of after fertilization.
Pickering etc. finds that the ovum of people in room temperature in transfer process, and since room temperature is lower than 37 DEG C, spindle can become in ovum
It is small, or even the microtubule depolymerization of spindle is caused, finally result in spindle disappearance.Almeida etc. has studied 18 people's ovums, discovery
Have within 5 minutes at room temperature and spindle disruption occurs in 72% ovum, 56% occurs the depolymerization separation of chromosome, damages after rewarming
Wound can not be restored., it was also found that when temperature is cooled to room temperature only 5 minutes, ovum changes for the research such as Simerly, or
Spindle become smaller or spindle in micro-pipe disintegration even disappear completely, metaphase chromosome is also in disorder distribution.5 will be placed at room temperature for
Minute or 15 minutes people's ovums put back in 37 DEG C of incubators again 1 or 4 hour, less than half of ovum restore to not by
The control ovum handled that cools down is similar.Within convalescence, if there is the variation of cell cycle, it will will lead to chromosome number
It is abnormal.Since fertilization process is the process that ovum completes second meiotic division, chromosome number purpose is abnormal, can all cause non-whole
The generation of times body embryo tire.
Therefore the existing mating constant temperature objective table of microscope is for ensuring that the temperature in culture dish, avoids occurring in ovum
The a series of poor prognosis such as spindle disruption.According to the requirement of assisted reproductive technology standard criterion program, the mating constant temperature of microscope
Objective table temperature should be set as 37 DEG C, and environment temperature is generally located between 23~25 DEG C, and liquor folliculi spreads out the big training in 10cm
It supports in ware, liquid heat loss is too fast, and the temperature of actual measurement liquor folliculi can be lower than set 5~6 DEG C of temperature.If set
It sets and is higher than 37 DEG C, and it is excessively high to will lead to local temperature in culture dish.It is special according to Human in vitro Fertilization-embryo transfer laboratory operation
It is pointed out in family's guide 2016, liquor folliculi temperature exceeds 36.4~36.9 DEG C of this ranges when taking ovum, all will affect embryonic blastula shape
At rate, implantation rate and live birth rate.Temperature of people's ovum in vitro in operating process has to be maintained at a more constant model
Within enclosing, the fluctuation of temperature is reduced to the greatest extent in operation.Research also found that slight temperature raising will increase more micro-
Pipe forms spindle, but 40 DEG C of higher temperature can destroy spindle.And this high temperature is irreversible to the destruction of spindle
, it can also inhibit cell division in the research discovery cultivation temperature raising of other animals or lead to embryonic death.The discovery such as Wang
If the temperature in culture drop is maintained at 37 DEG C, the presence of spindle can be observed in more ovums.These ovums by
After essence, rate of fertilization and pregnancy rate have to be improved significantly.It can be seen that development of the stabilization of temperature to ovum when Microfertilization
It is considerable.
Assisted reproductive technology is developed so far, and is not occurred both at home and abroad constant before system, overall process, comprehensive ovum fertilization
Temperature control equipment covering takes ovum and picks up ovum overall process.Existing constant temp test tube rack and constant temperature objective table, which solve only, to be taken ovum and picks up
During ovum, portion link and local temperature control method are unable to reach system, overall process and in all directions in a stable temperature
Spend range.
