Description
Technical field
The utility model relates to a kind of storage facilities, particularly relates to a kind of biological specimen holding vessel.
Background technology
Liquid nitrogen is widely used in medical research and clinical field as a kind of cryogen.Medical personnel place well-bucket by sample and to be suspended in biological specimen holding vessel by sample and to preserve.In order to avoid because temperature difference quickening is volatilized and supplemented the liquid nitrogen that sample is placed in well-bucket, usually can be provided with opening in the bottom of sample placement well-bucket, the liquid nitrogen in sample placement well-bucket is communicated with the liquid nitrogen in biological specimen holding vessel.Because the liquid nitrogen of liquid nitrogen storage tank communicates with the liquid nitrogen that each sample is placed in well-bucket, when multisample is preserved, easily cause the mutual pollution between sample, there is potential safety hazard.Meanwhile, existing biological specimen holding vessel needs manually to carry out liquid level to be checked, regularly adds liquid nitrogen, this work not only waste of manpower, still exists and can not place the potential safety hazard of adding liquid nitrogen in well-bucket to sample in time.
Utility model content
The storing mode that the utility model overcomes biological specimen holding vessel of the prior art easily causes the mutual pollution between sample and needs manually to carry out the shortcoming that liquid level checks, provides a kind of biological specimen holding vessel.
The technical scheme that the utility model realizes goal of the invention employing is: a kind of biological specimen holding vessel, comprise the holding vessel body that liquid nitrogen is housed, well-bucket placed by the one group of sample be suspended in holding vessel, the semi-closed structure that well-bucket is only one end open placed by described sample, also comprise liquid nitrogen added automatically system, described liquid nitrogen added automatically system comprises liquid nitrogen pump, liquid surface height sensor and liquid nitrogen delivery pipe, liquid surface height sensor is electrically connected with the control circuit of liquid nitrogen pump, sample is placed the height conversion of liquid level in well-bucket and is become electric signal to control the opening and closing of liquid nitrogen pump by liquid surface height sensor, liquid nitrogen delivery pipe one end connects with liquid nitrogen delivery side of pump, the opening that well-bucket placed by the liquid nitrogen delivery pipe other end and sample connects.
Described liquid surface height sensor is arranged on sample and places on well-bucket, and the adjustable structure of well-bucket height of formation placed by liquid surface height sensor and sample.
The liquid nitrogen delivery pipe that well-bucket correspondence is provided with a liquid surface height sensor and opens separately placed by each described sample.
Described liquid nitrogen pump is arranged on outside holding vessel.
The beneficial effects of the utility model are: it is closed that sample of the present utility model is placed bottom well-bucket, and each sample is placed between well-bucket and do not communicated, and has stopped the possibility mutually polluted between sample, has improve the safety of storage.Sample of the present utility model is placed well-bucket and is still immersed in liquid nitrogen, solves the problem because of temperature difference quickening volatilization.By increasing liquid surface height sensor, when being checked through height that sample places liquid level in well-bucket lower than setting value, automatically opening liquid nitrogen pump and liquid nitrogen clean in holding vessel being transported to sample and placing in well-bucket.Owing to detecting for 24 hours, not only reduce manual operation cost, also add safety.
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model will be further described.
Accompanying drawing explanation
Fig. 1 is cross-sectional schematic of the present utility model.
In accompanying drawing, 1 for liquid nitrogen added automatically system, 1-1 be liquid nitrogen pump, 1-2 is liquid surface height sensor, 1-3 be liquid nitrogen delivery pipe, 2 is liquid nitrogen, 3 be holding vessel, 4 to place well-bucket, 5 for sample be biological specimen.
Detailed description of the invention
As shown in drawings, a kind of biological specimen holding vessel of the present embodiment, comprises holding vessel 3 body that liquid nitrogen 2 is housed, and well-bucket 4 placed by the one group of sample be suspended in holding vessel 3.The semi-closed structure that well-bucket 4 is only one end open placed by described sample, and opening is not established in sidewall and the bottom of sample placement well-bucket 4.Also comprise liquid nitrogen added automatically system 1.Described liquid nitrogen added automatically system 1 comprises liquid nitrogen pump 1-1, liquid surface height sensor 1-2 and liquid nitrogen delivery pipe 1-3.Liquid surface height sensor 1-2 is electrically connected with the control circuit of liquid nitrogen pump 1-1, the height conversion that liquid level in well-bucket 4 placed by sample by liquid surface height sensor 1-2 becomes electric signal to control the opening and closing of liquid nitrogen pump 1-1, liquid nitrogen delivery pipe 1-3 one end connects with the mouth of liquid nitrogen pump 1-1, and the liquid nitrogen delivery pipe 1-3 other end connects with the opening that well-bucket 4 placed by sample.Liquid surface height sensor 1-2 can select also can selecting of contact contactless.When selecting the sensor of contact, the preferred liquid surface height sensor 1-2 of the present embodiment is arranged on sample and places on well-bucket 4, and the adjustable structure of well-bucket 4 height of formation placed by liquid surface height sensor 1-2 and sample.By the setting height(from bottom) of adjustment liquid surface height sensor 1-2, control the critical height of opening liquid nitrogen pump 1-1.Consider low temperature and the convenient for maintaining of liquid nitrogen 2, the preferred liquid nitrogen pump 1-1 of the present embodiment is arranged on outside holding vessel 3.
In order to control liquid nitrogen 2 capacity in each sample placement well-bucket 4 more accurately, the liquid nitrogen delivery pipe 1-3 that well-bucket 4 correspondence is provided with a liquid surface height sensor 1-2 and opens separately placed by the present embodiment each sample preferred.
During actual use, in holding vessel 3, add clean liquid nitrogen 2, one group of sample that biological specimen 5 is housed is placed well-bucket 4 and is suspended in holding vessel 3.Liquid surface height sensor 1-2 detects the height that liquid level in well-bucket 4 placed by sample, when the height of liquid level in sample placement well-bucket 4 is lower than setting value, automatic unlatching liquid nitrogen pump 1-1, is transported to sample by liquid nitrogen 2 clean in holding vessel 3 by liquid nitrogen delivery pipe 1-3 and places in well-bucket 4.When the height of liquid level in sample placement well-bucket 4 is higher than setting value, automatically close liquid nitrogen pump 1-1.In order to the liquid nitrogen 2 preventing one group of sample from placing in well-bucket 4 communicates, liquid nitrogen 2 electrolyte level in holding vessel 3 can not place the opening of well-bucket 4 higher than sample.Liquid surface height sensor 1-2 detects the height that liquid level in well-bucket 4 placed by sample in real time, does not need manually to carry out checking and regularly adds, and adds when only needing the liquid nitrogen 2 in holding vessel 3 not enough again.
