Abstract
The utility model discloses a liquid nitrogen container used to preserve a tissue sample. The liquid nitrogen container used to preserve the tissue sample comprises a liquid nitrogen container body and a sample frame arranged in the liquid nitrogen container body, and is characterized in that the sample frame is divided into a plurality of independent separate sample frames, wherein each separate sample frame at least comprises an arc-shaped draw bar attached to the inner wall of the liquid nitrogen container body and a storage cell arranged at the tail end of the draw bar, and each storage cell is tightly attached to the inner wall of the liquid nitrogen container body under the effect of the arc-shaped draw bar. The sample frame is divided into the plurality of separate sample frames, the draw bar of each separate sample frame is of an arc-shaped structure consistent with a line of the inner wall of the liquid nitrogen container body, and the separate sample frames are arranged in the liquid nitrogen container body and tightly attached to the inner wall of the liquid nitrogen container body under the effect of the arc-shaped draw bars. When the separate sample frames are pulled upwards, due to the fact that the opening of the liquid nitrogen container body is of an upward shrink structure, the upward motion of the draw bars simultaneously drives the separate sample frames to move towards the middle, consequently even for the separate sample frames of a multiple structure, the upper layer separate sample frames do not affect pulling out of the lower layer separate sample frames.
Description
Technical field
The utility model relates to a kind of apparatus for placing of medically tissue specimen, is specifically related to a kind of liquid nitrogen container for preserving tissue specimen.
Background technology
Tissue specimen in the hospital, especially tumor tissues all are to store with liquid nitrogen container usually.Be placed with specimen holder in the liquid nitrogen container, liquid is placed on the specimen holder and then immerses in the liquid nitrogen.Specimen holder in the existing liquid nitrogen container is sandwich construction up and down, sample is placed on respectively in the different layers structure, deposit or when taking sample away at every turn, whole specimen holder need to be taken out liquid nitrogen container, the sample (comprising the sample that need not to take out) that will cause like this all to be placed in the specimen holder all can be removed liquid nitrogen container, not only can be to the tissue specimen injury, and the while is long owing to the operating time, easily make again the liquid nitrogen volatilization, the waste liquid nitrogen.
The utility model content
The utility model purpose: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of and can take out as required corresponding sample, makes things convenient for the liquid nitrogen container that is used for preserving tissue specimen of access.
Technical scheme: the liquid nitrogen container for preserving tissue specimen described in the utility model, comprise liquid nitrogen container body and the specimen holder that is arranged in the described liquid nitrogen container body, described specimen holder is several independently split specimen holders, each split specimen holder comprises the arc pull bar of fitting with the liquid nitrogen container inwall and the storage unit lattice that are arranged on the pull bar end at least, and each storage unit lattice is close to the liquid nitrogen container inwall under the effect of arc pull bar.
Preferably, several split specimen holders circular array of arranged in a parallel on the same level in liquid nitrogen container at least.
In order to take full advantage of the inner space of liquid nitrogen container, several split specimen holders of the utility model are arranged in the layer 2-3 structure, and every layer of structure is by circular array of arranged in a parallel on the same level of some split specimen holders in liquid nitrogen container.
For the taking-up of convenient corresponding sample, the upper end of described arc pull bar is provided with hook, and hook is connected with the fixture of liquid nitrogen container opening part; Be provided with tag board on the hook.
The utility model compared with prior art, its beneficial effect is: 1, the utility model improves the specimen holder in the existing liquid nitrogen container, the structure of liquid nitrogen container can not destroyed the security performance of liquid nitrogen container without any changes; 2, specimen holder is several split specimen holders, and the pull bar of each split specimen holder is the arcuate structure consistent with liquid nitrogen container inwall lines, and this split specimen holder is placed on all is close to the liquid nitrogen container inwall under the effect of arc pull bar in the liquid nitrogen container; When upwards pulling out the split specimen holder, because the liquid nitrogen container opening is contraction structure upwards, pull bar upwards drives the split specimen holder when operation and moves to mid portion, even the therefore split specimen holder of sandwich construction, the upper strata specimen holder can not affect pulling out of lower floor's specimen holder yet; 3, the utility model is simple in structure, and is easy to use, can take out as required corresponding sample, need not all samples are taken out together.

Embodiment
The below is elaborated to technical solutions of the utility model, but protection domain of the present utility model is not limited to described embodiment.
The liquid nitrogen container that is used for preserving tissue specimen shown in Fig. 1～3, comprise liquid nitrogen container body 1 and the specimen holder that is arranged in the described liquid nitrogen container body, described specimen holder is several independently split specimen holders 2, each split specimen holder 2 comprises the arc pull bar 2-1 that fits with the liquid nitrogen container inwall and the storage unit lattice 2-2 that is arranged on the pull bar end at least, and each storage unit lattice 2-2 is close to the liquid nitrogen container inwall under the effect of arc pull bar; Several split specimen holders 2 are circular array of arranged in a parallel on the same level in liquid nitrogen container at least.Also can be that several split specimen holders are arranged in 2～3-tier architecture, every layer of structure be by circular array of arranged in a parallel on the same level of some split specimen holders in liquid nitrogen container, and such structure is conserve space relatively, and the present embodiment is not shown in FIG..The upper end of described arc pull bar 2-1 is provided with hook 2-3, and hook is connected with the fixture of liquid nitrogen container opening part; Be provided with tag board on the hook.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
