Abstract
The novel liquid nitrogen being applicable to sperm freezing fumigates a box, comprises box body, lid, bar shaped support, froth bed, metal level; The opening of described box body is provided with lid; Described box body skin is froth bed, and the internal layer of box body is metal level, and metal level both sides are equipped with bar shaped support.Be closed state when the utility model is owing to using, the temperature in box comparatively open-type to fumigate box lower, seminal fluid can be made to be down to-30 DEG C fast; And liquid nitrogen volatilization is slow, each stifling need consume a small amount of liquid nitrogen, and because stripe shape support can place two to three layers of aluminum frame, each stifling semen sample quantity is traditional two to three times, increases operating efficiency.
Description
Technical field
The liquid nitrogen that the utility model is applicable to sperm freezing fumigates box.
Background technology
It is one of important step in sperm freezing operation that liquid nitrogen is fumigated, and is be placed in above liquid nitrogen by seminal fluid and freezing liquid mixture, utilizes liquid nitrogen vapor to make seminal fluid be chilled to the process of-30 DEG C in advance.The way of the stifling seminal fluid of tradition is: be stuck in aluminum frame by the test tube that seminal fluid and freezing liquid are housed, and aluminum frame is ridden over liquid nitrogen and fumigates above box stifling.This operation has following deficiency: 1. fumigating box due to traditional liquid nitrogen is open-type, liquid nitrogen volatilization is very fast, and each stifling needs pours a large amount of liquid nitrogen in stifling box, causes waste, and due to box, temperature is higher outward, needs the long period seminal fluid temperature could be down to-30 DEG C.2, the semen sample negligible amounts of each stifling box process, efficiency is low.
Utility model content
The purpose of this utility model is the defect overcoming the existence of above-mentioned technology, provides a kind of liquid nitrogen being applicable to sperm freezing to fumigate box.
The novel liquid nitrogen being applicable to sperm freezing fumigates a box, comprises box body, lid, bar shaped support, froth bed, metal level; The opening of described box body is provided with lid; Described box body skin is froth bed, and the internal layer of box body is metal level, and metal level both sides are equipped with bar shaped support.
Described box body is long is 30cm, and wide is 15cm.
Described bar shaped support is four.
Described bar shaped support is six.
The beneficial effect of employing technique scheme is:
Be closed state when the utility model is owing to using, the temperature in box comparatively open-type to fumigate box lower, seminal fluid can be made to be down to-30 DEG C fast; And liquid nitrogen volatilization is slow, each stifling need consume a small amount of liquid nitrogen, and because stripe shape support can place two to three layers of aluminum frame, each stifling semen sample quantity is traditional two to three times, increases operating efficiency.
Accompanying drawing explanation
Fig. 1 is that the liquid nitrogen that the utility model is applicable to sperm freezing fumigates box structural representation.
In figure: 1-box body, 2-lid, 3-bar shaped support, 4-froth bed, 5-metal level.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The novel liquid nitrogen being applicable to sperm freezing fumigates a box, comprises box body 1, lid 2, bar shaped support 3, froth bed 4, metal level 5; The opening of described box body 1 is provided with lid 2; Described box body 1 skin is froth bed 4, and the internal layer of box body 1 is metal level 5, and the effect of froth bed 4 is isolated temperature, cannot take because box body 1 is too cool, the effect of metal level 5 is in order to more convenient time clean, and traditional box body 1 only has one deck froth bed 4, and metal level 5 both sides are equipped with bar shaped support 3.
Described box body 1 is long is 30cm, and wide is 15cm.
Described bar shaped support 3 is four.
Described bar shaped support 3 is six.
The utility model, in embody rule process, is first poured a small amount of liquid nitrogen into, is stuck in aluminum frame, aluminum frame is positioned over the test tube that seminal fluid and freezing liquid are housed on bar shaped support 3 in box body 1, then covers lid 2 and can fumigate.
