The cord blood stem cell holding vessel of prior art can not accurately control very much temperature, temperature error is the biggest, there is liquid nitrogen surplus too low, temperature raises, the risk of the cord blood stem cell damage stored, causes cytoactive to reduce, even dead, and it is vented directly to after liquid nitrogen gasification in air, causes the waste of consummate nitrogen.
Utility model content
In order to overcome the cord blood stem cell stored in prior art storage tank easily damaged and the deficiency of liquid nitrogen waste, this utility model provides the safe storage device of a kind of cord blood stem cell, it is capable of detecting when the temperature and pressure of cold preservation stem cell environment, feed in time when liquid nitrogen is inadequate, and the liquid nitrogen raising gasification because of temperature can be recycled.
To achieve these goals, this utility model adopts the following technical scheme that
A kind of safe storage device of cord blood stem cell, it is characterized in that including liquid nitrogen storage tank, casing, air accumulator, it is connected by the first electromagnetic valve between described liquid nitrogen storage tank with described casing, being connected by the second electromagnetic valve between described casing with described air accumulator, described first electromagnetic valve is connected with PLC respectively with described second electromagnetic valve.
Described casing includes the refrigerating chamber of superposed gas collection chamber and bottom, connected by gas passage between described gas collection chamber and described refrigerating chamber, described refrigerating chamber top is provided with opening, it is provided with household freezer in described refrigerating chamber, form liquid nitrogen storage chamber between described household freezer and described refrigerating chamber, in described household freezer, be provided with the storage box connected by support.
Described liquid nitrogen storage tank is stored chamber with the described liquid nitrogen in described casing and is connected by described first electromagnetic valve.
Described air accumulator is connected by the second electromagnetic valve with the described gas collection chamber in described casing.
Described liquid nitrogen storage intracavity is provided with liquid level sensor, temperature sensor, and described liquid level sensor, described temperature sensor are connected with described PLC respectively.
Described collection and confinement of gases indoor are provided with pressure transducer, and described pressure transducer is connected with described PLC.
Also include that alarm, described alarm are connected with described PLC.
The beneficial effects of the utility model are: by temperature sensor, the setting of liquid level sensor, the temperature of liquid nitrogen and the liquid level of liquid nitrogen in refrigerating chamber is made to be monitored accurately, when causing freezing indoor temperature rising or nitrogen gasification to cause liquid level to reduce due to heat exchange, during so that the stem cell in storage box can not preserve at a suitable temperature, system can feed liquid nitrogen automatically, and reports to the police；Add gas collection chamber, temperature is raised the liquid nitrogen gas caused and is collected, and send into air accumulator in time, liquid nitrogen will not be caused waste, reduce cost.This utility model is capable of detecting when the temperature and pressure of cold preservation stem cell environment, feeds in time when liquid nitrogen is inadequate, it is ensured that the safety of the cord blood stem cell of storage, and can recycle the liquid nitrogen raising gasification because of temperature.
