Abstract
The utility model discloses a stem cell storage pot with an automatic liquid nitrogen filling control device. The stem cell storage pot comprises an inner container and an outer container which form the storage pot, wherein a vacuum interlayer is formed between the inner container and the outer container; a pressure sensor is arranged at the bottom of the outer wall of the inner container; a liquid nitrogen pipeline leading to the inner container is arranged at the bottom of the outer side surface of the stem cell storage pot; an electromagnetic valve for controlling the liquid nitrogen pipeline to open and close is arranged on the liquid nitrogen pipeline; a liquid nitrogen pot is externally connected to the liquid nitrogen pipeline; the pressure sensor and the electromagnetic valve are connected with a controller; and the controller controls the electromagnetic valve to open and close according to data transmitted by the pressure sensor. The stem cell storage pot can be monitored in real time; and nitrogen can be filled into the storage pot at any time according to the change of a liquid level of the liquid nitrogen to ensure that stored stem cells are in low temperature state for a long time.
Description
Technical field
The utility model relates to a kind of stem cell holding vessel, especially a kind ofly has a stem cell holding vessel that liquid nitrogen fills control device automatically.
Background technology
The stem cell holding vessel is that stem cell stores utensil commonly used in the engineering; Existing stem cell holding vessel is made up of inner bag and outer courage; Form vacuum interlayer between inner bag and the outer courage, be used to keep low temperature, the stem cell that need store is put in the bottom of inner bag; In inner bag, be filled with liquid nitrogen, be used for the low-temperature preservation stem cell.
But the stem cell holding vessel of prior art because the loss of energy has part liquid nitrogen gasification to occur, reduces the liquid level of liquid nitrogen, influences the low-temperature storage of stem cell.
The utility model content
The utility model technical problem to be solved is that a kind of stem cell holding vessel that liquid nitrogen fills control device automatically that has that can fill nitrogen automatically is provided.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind ofly have a stem cell holding vessel that liquid nitrogen fills control device automatically, comprise the inner bag and the outer courage that constitute holding vessel, form vacuum interlayer between inner bag and the outer courage; Outer wall bottom at inner bag is provided with pressure sensor; Stem cell holding vessel exterior lateral sides bottom is provided with the liquid nitrogen pipes that feeds in the inner bag, and liquid nitrogen pipes is provided with the magnetic valve that the control liquid nitrogen pipes opens and closes, the external liquid nitrogen container of liquid nitrogen pipes; Pressure sensor links to each other with controller with magnetic valve, and controller is according to the switching of the transmission Data Control magnetic valve of pressure sensor.
The beneficial effect of the utility model is: can monitor in real time the stem cell holding vessel, at any time according to the liquid nitrogen liquid level variation, holding vessel in time filled nitrogen, guarantee that the stem cell of preservation is in low-temperature condition for a long time.
Description of drawings
Fig. 1 is the sketch map that liquid nitrogen fills the stem cell holding vessel of control device automatically that has of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:
The operation principle of the stem cell holding vessel of the utility model is identical with prior art; Can be with reference to prior art; So no longer narration, the difference of the utility model and prior art is to have increased liquid nitrogen to fill control device automatically, carries out detailed explanation below:
As shown in Figure 1; The utility model have a stem cell holding vessel that liquid nitrogen fills control device automatically, comprise the inner bag 1 and outer courage 2 that constitute holding vessel, form vacuum interlayer between inner bag 1 and the outer courage 2; Outer wall bottom at inner bag 1 is provided with pressure sensor 3; Stem cell holding vessel exterior lateral sides bottom is provided with the liquid nitrogen pipes 4 that feeds in the inner bag 1, and liquid nitrogen pipes 4 is provided with the magnetic valve 5 that the control liquid nitrogen pipes opens and closes, liquid nitrogen pipes 4 external liquid nitrogen container (not shown); Pressure sensor 3 links to each other with controller 6 with magnetic valve 5, and controller 6 is according to the switching of the transmission Data Control magnetic valve 5 of pressure sensor 3.
Specifically, the stem cell that needs are stored is placed into inner bag 1 bottom, charges into liquid nitrogen; Make stem cell be immersed in the liquid nitrogen fully; This moment, the height of liquid nitrogen was H1, opened liquid nitrogen and filled control device automatically, be i.e. pressure sensor 3, controller 6; The pressure of pressure sensor 3 impressions this moment is greater than the pressure P of setting of closing magnetic valve 1, and magnetic valve 5 cuts out.Because energy loss, the liquid nitrogen gasification in the holding vessel inner bag makes the liquid level of liquid nitrogen drop to H2; The pressure of pressure sensor 3 impressions this moment is less than the pressure P 2 of the opens solenoid valve of setting, and magnetic valve 5 is opened, and liquid nitrogen gets in the inner bag through liquid nitrogen pipes 4; When the liquid level of liquid nitrogen rises to H1; Be pressure sensor 3 impression pressure greater than set close the pressure P 1 of magnetic valve the time, control signal sends controller 6 to, controller 6 control magnetic valves 5 cut out; Repeat said process repeatedly, reach the purpose of filling nitrogen automatically.
In sum; The content of the utility model is not confined in the above embodiments; Knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the utility model, but this embodiment is included within the scope of the utility model.
