Description

A kind of irradiation unit filling bar for observing embryo under liquid nitrogen

Technical field

The utility model relates to medical instruments field more particularly to a kind of irradiation dresses that bar is filled for observing embryo under liquid nitrogen It sets.

Background technique

With the relieving of national " two children " policy comprehensively, more and more women have regeneration to educate demand.But since the age increases Greatly, environmental pollution, job and life stress be big and the overlaying influence of the factors such as bad life style, the current every 7 couples of Mr. and Mrs in China In there are about 1 pair can not carry out normal reproduction, this would have to by supplementary reproduction (test-tube baby) technology.

And when embryo experiments room carries out IVF-ET (in vitro fertilization-embryo transfer) operation, often it will appear using embryo Situations such as tire number is not in the best embryo transfer phase greater than transplanting embryo number or wife's side endometrium, at this time just must be to embryo Tire carries out freezen protective operation.

Embryo had to pass through before carrying out long-term frozen preservation dress bar the step of, and the step for overall process must be in liquid It completes, but liquid nitrogen has extremely strong volatility, is understood in the fog of liquid nitrogen surface formation one thickness weight under state nitrogen, and liquid nitrogen and air Belong to different media again, light, which enters liquid nitrogen, can occur refraction effect, and embryo experiments room integrated environment is partially dark in addition, so that seeing It is very difficult to examine embryo's dress bar under liquid nitrogen.

In order to which transmission nitrogen vapor can preferably observe the dress bar position of embryo under liquid nitrogen to guarantee the dress bar effect of embryo, Laboratory operation personnel often by head as much as possible close to liquid nitrogen liquid level, while as far as possible shorten carry bar reach liquid level away from From, but this there is because observe it is unclear due to do not control relative distance make carry bar emersion liquid nitrogen liquid level risk, and once plus The load bar for having carried embryo will cause the injury of lethal departing from liquid nitrogen to embryo；Meanwhile lab assistant is apart from liquid nitrogen mistake Closely, the liquid nitrogen volatilized can be sucked, once and liquid nitrogen sputter come, easily the eyes of personnel and skin are damaged.

Therefore, experimenter visually observes under liquid nitrogen embryo and fills bar and exist and do not see, is easy to cause load bar in the prior art Emersion liquid nitrogen liquid level and haves the defects that human injury to experimenter.

Summary of the invention

It visually observes under liquid nitrogen embryo and fills bar and exist to solve experimenter in the prior art and do not see, be easy to cause load Bar emersion liquid nitrogen liquid level and there are problems that human injury to experimenter, the utility model provides a kind of irradiation and penetrates effect Good, easy to use and flexible and the irradiation unit that bar is filled for observing embryo under liquid nitrogen for having both safeguard function.

The technical solution that the utility model solves the above problems is:

Embodiments herein provide it is a kind of fill the irradiation unit of bar for observing embryo under liquid nitrogen, including can be fixed on and make The cap body on user head, the cap body include first half and latter half；The lower section of the first half is equipped with for blocking The goggles of user's eyes, and the goggles can be rotated by the first rotating device and the first half can positioningly be arranged in Partial cap is along upper；
