Description
Technical Field
The utility model relates to a liquid nitrogen cell freezing device, in particular to a liquid nitrogen cell freezing and storing transportation device.
Background
Many cell samples are routinely stored in liquid nitrogen and, when transported over long distances, need to be kept cold in liquid nitrogen during transport. Various cell cryopreservation and transportation devices capable of being filled with liquid nitrogen exist in the market, but generally, a cell sample is wholly or partially immersed in the liquid nitrogen, so that two problems are caused, firstly, when the cell sample is taken, the material for holding the cells is fragile due to extremely low temperature, the taking is very careful and the consumed time is long, the liquid nitrogen is volatilized in large quantity, waste is caused, and meanwhile, the temperature of the sample taken out later is possibly increased due to the fact that the liquid nitrogen for keeping low temperature is lost in large quantity; secondly, liquid nitrogen volatilization can obstruct the sight and easily cause misoperation.
SUMMERY OF THE UTILITY MODEL
In view of the defects, the utility model provides the liquid nitrogen cryopreserved cell transportation device, which does not volatilize liquid nitrogen when taking a sample, is less in waste, has a good heat preservation effect and is less in operation errors.
In order to achieve the above purpose, the embodiment of the utility model adopts the following technical scheme:
a liquid nitrogen cryopreserved cell transportation device comprises an outer box and an inner box arranged in the outer box, wherein the upper wall surface of the inner box is provided with a plurality of tubular grooves, and sample tubes for storing cell samples are placed in the tubular grooves; liquid nitrogen is stored in the inner box.
According to one aspect of the utility model, the outer box comprises an outer box body and an outer box cover, and a sealing ring is arranged at the joint of the outer box cover and the outer box body.
According to one aspect of the utility model, the wall of the outer box is hollow and filled with a heat insulating material.
According to one aspect of the utility model, the inner box comprises an inner box body and an inner box cover, wherein an external thread is arranged at the joint of the inner box body and the inner box cover, an internal thread is arranged at the joint of the inner box cover and the inner box body, and the inner box body and the inner box cover are in threaded connection through the external thread and the internal thread.
According to one aspect of the utility model, the outer box body and the inner box body are both provided with a lifting handle.
The implementation of the utility model has the advantages that: the liquid nitrogen cryopreserved cell transportation device comprises an outer box and an inner box arranged in the outer box, wherein a plurality of tubular grooves are formed in the upper wall surface of the inner box, and sample tubes for storing cell samples are placed in the tubular grooves; liquid nitrogen is stored in the inner box, so that the liquid nitrogen is stored in the inner box in a sealed mode, the sample tube is placed in the tubular groove, the tubular groove can be kept at a low temperature through the liquid nitrogen, the sample tube is kept at the low temperature, the liquid nitrogen cannot volatilize when the sample tube is taken, waste is little, the heat preservation effect is good, and operation errors are few.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural diagram of a liquid nitrogen cryopreserved cell transportation device according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the liquid nitrogen cryopreserved cell transportation device comprises an outer box and an inner box arranged in the outer box, wherein the upper wall surface of the inner box is provided with a plurality of tubular grooves, and sample tubes 1 for storing cell samples are placed in the tubular grooves; liquid nitrogen is stored in the inner box.
The liquid nitrogen is stored in the inner box, and does not need to be directly contacted with the outer wall of the tubular groove in practical application, if the temperature of the tubular groove rises, a small amount of volatilized liquid nitrogen in the inner box can be condensed at the outer wall of the tubular groove to adjust the temperature, so that the temperature of the tubular groove is kept at a low level. The tubular groove and the sample tube exchange heat through heat conduction. In practice, the walls of the tubular recess should not be too thick, preferably not more than 2mm, to ensure a heat-conducting effect.
The outer box comprises an outer box body 2 and an outer box cover 3, and a sealing ring is arranged at the joint of the outer box cover and the outer box body. And the wall of the outer box is hollow and is filled with heat insulation materials.
The outer box mainly provides a better space of heat-proof quality for storing the inner box of liquid nitrogen. The wall of the outer box body can be filled with heat insulating materials such as sponge, aerogel and the like. In this embodiment, the connection between the outer box and the outer box cover is a screw connection, specifically, an external thread is provided at the joint of the outer box and the outer box cover, and an internal thread is provided at the joint of the outer box cover and the outer box. The sealing performance of spiro union is relatively good, sets up the sealing washer simultaneously and further guarantees sealed effect, prevents the heat convection heat transfer.
The inner box comprises an inner box body 4 and an inner box cover 5, an external thread is arranged at the joint of the inner box body and the inner box cover, an internal thread is arranged at the joint of the inner box cover and the inner box body, and the inner box body and the inner box cover are connected through the external thread and the internal thread in a screwed mode. The screw joint has good sealing performance and can prevent the liquid nitrogen from volatilizing and dissipating.
The outer box body and the inner box body are both provided with lifting handles 6.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed herein are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
