Description
Technical field
It the utility model is related to sample fishing device under a kind of liquid nitrogen.
Background technology
In human reproduction's genetic laboratory, some are not reaching with subsample (sperm, ovum) and zygote sample (embryo)
During to optimal in vitro fertilization or transplanting (IVF/ET) opportunity, generally require to carry out freezen protective under long-term ultra-low temperature liquid nitrogen.And with
The relieving of comprehensive " two children " policy, increasing elder women and infertile patient requests help supplementary reproduction (ART)
Technology, which results in the gamete for needing to be frozen or the increasing number of zygote sample.However, sample enter or leave-
Surface, which easily freezes, during 196 DEG C of liquid nitrogen skids and drops to liquid nitrogen container bottom, and with the increase of sample size, this feelings occurs
The number of condition also greatly increases.Make narrow space due to storing great amount of samples in the ultralow temperature characteristics and tank body of liquid nitrogen, test
Hand can not be directly protruding under liquid nitrogen and pick up by room personnel, encounter such situation, first can only shift the sample in tank, then pour out
Whole liquid nitrogen and tank bottom sample in tank, then sample and liquid nitrogen are shifted back again.This operation is not only wasted time and energy, and
Liquid nitrogen a large amount of volatilizations caused by toppling over have a negative impact to the health of lab assistant.
The content of the invention
Insufficient existing for above-mentioned background technology in order to overcome, the utility model proposes one kind not to need remaining sample in transfer tank
Originally and liquid nitrogen is toppled over, and the structure for directly going deep into salvaging the sample for falling tank bottom under liquid nitrogen to come is simple, easy to operate, clear
Sample fishing device under clean free of contamination liquid nitrogen.
Sample fishing device under a kind of liquid nitrogen described in the utility model, it is characterised in that：Including grabbing device and sterilization
Device, the grabbing device are grabbed including the stock for stretching into liquid nitrogen, the handgrip for catching sample and for adjusting
Hand firmly grasps the adjusting rod of dynamics, and the lower end of the stock is equipped with the handgrip of multijaw, and in opening under the handgrip nature
State；It is furnished with grip part in the upper end of the stock；The adjusting rod top is provided with handle, and bottom, which is equipped with, to be used to enclose outside handgrip
The collar, and the decline that passes through the collar/gathering for rising control handgrip/is unclamped；The chlorination equipment includes base, lighttight
Cylinder and the uviol lamp for sterilizing grabbing device, the cylinder body bottom and the base are affixed, the cylinder open topped,
The uviol lamp is mounted in the inner barrel.
The handgrip is the hand-type structure being made up of five arc clamp holders, and arc clamp holder is real with decline/rising of annulus
Now gather/unclamp, the grasping end of each arc clamp holder is firmly cased with the coarse Rubber end of outside smooth inside.
The top of the stock is provided with and displays whether to grab the mark scale of sample, wherein being identified as two along stock axle
To the groove of setting, the groove mark of top, which represents, to be captured successfully, and the groove mark of lower section, which represents, does not capture or capture failure.
The barrel of the cylinder is provided with the groove for being used for shelving grabbing device.
The cylinder is six hollow prisms, and the madial wall of the cylinder pastes the mirror for light reflection ultraviolet.
Edge is provided with groove in symmetrical two side walls of cylinder.
Application method of the present utility model is as follows：When hair available sample falls into liquid nitrogen container bottom, first open ultraviolet in cylinder
Lamp is disinfected to grabbing device progress 10-15 minutes.Afterwards, a lab assistant holds the side grip of liquid nitrogen container two by tank
Body tilts 10 ° -15 ° towards side so that sample rolls down to the side bottom of tank body one.And another hand of lab assistant two is held respectively
The handle of stock grip part and adjusting rod, grabbing device is extend into liquid nitrogen container bottom from liquid nitrogen tank mouth, two bars are closed up after bottoming out,
Adjusting rod is axially downwardly pushed to drive five arc clamp holders of " hand-type " handgrip of stock lower end to gather along stock.Due to liquid
Nitrogen volatilization hazes, pickup success or not can not be observed directly, if adjusting rod push downwards distance it is longer, reach stock " do not obtain
Take " groove mark, show that handgrip uses leisure moments, if push is not up to " not obtaining " scale and met obstructions adjusting rod downwards so that adjust
Pole is located exactly at " acquisition " groove mark, shows that handgrip has caught sample.Dynamics should be now controlled, keeps two bars with respect to position
Put motionless, clamp and simultaneously carefully take out sample from liquid nitrogen container.
The beneficial effects of the utility model：
1) use of sample fishing device eliminates remaining sample in transfer tank and topples over the steps such as liquid nitrogen under the liquid nitrogen, greatly
Time and manpower are saved greatly, also effectively prevent remaining sample caused security risk in transfer process, while also reduce
Because liquid nitrogen volatilizees to health hazards caused by lab assistant；
2) under the liquid nitrogen handgrip head of sample fishing device cover the smooth Rubber end in outside then effectively prevent it is stainless
Steel steel pawl (vacuumizes, if to destroy vacuum final for internal layer damage to the mechanical damage of liquid nitrogen container internal layer between liquid nitrogen container ectonexine
Cause the forfeiture for freezing effect)；
3) setting that " acquisition " and " not obtaining " groove identifies on stock in sample fishing device under the liquid nitrogen so that seeing
It still could be aware that whether sample obtains in the case of unclear tank bottom to salvage successfully；
4) setting of each face upper reflector enhances uviol lamp in the long cylinder of hexagon in sample fishing device under the liquid nitrogen
Disinfection Effect, avoid pollution of the fishing device to liquid nitrogen in itself；
5) setting of two grooves of opposite side causes fishing device at the top of the long cylinder of hexagon in sample fishing device under the liquid nitrogen
In the more stable safety of placement usually and sterilization.
