Description
Technical field
The present invention relates to the journeys that the cooling instrument to cool down to biological tissue more particularly to a kind of band can write cooling process
Sequence cooling instrument.
Background technique
In the preservation of cell and biological tissue, temperature-fall period breaks the motility rate after cell and tissue recovery with institutional framework
Bad degree has a great impact.There are two types of current more common cooling methods: 1 uses liquid nitrogen for the programmable journey of temperature-reducing medium
Sequence cooling instrument；2 program temperature reduction boxes cooperated using ultra low temperature freezer.Both cooling methods are widely used in scientific research and production
While, expensive there is also programmable programmed cooling instrument device and need to consume liquid nitrogen, program temperature reduction box cannot root
The problem of changing temperature lowering curve according to specific requirements.
Summary of the invention
To overcome disadvantages mentioned above, the purpose of the present invention is to provide one kind can utilize existing ultra low temperature freezer, is not required to additional
Purchasing procedure cooling instrument and liquid nitrogen, the cooperation ultra low temperature freezer that cell and biomaterial can also be programmed according to specific requirements
The band used can write the programmed cooling instrument of cooling process.
In order to reach the goals above, the technical solution adopted by the present invention is that: a kind of band can write the program drop of cooling process
Wen Yi, including the acquisition of refrigerator, data and control device, insulated cabinet, the insulated cabinet are arranged in refrigerator inside, the insulated cabinet
Portion's storage has cell and biological material containers, and solenoid valve connection is isolated with the cavity of refrigerator and is passed through to the cavity of the insulated cabinet,
The temperature inductor of the cavity temperature to survey insulated cabinet is provided in the insulated cabinet, the temperature inductor is adopted with data
Collection is connect with the input terminal of control device, and the data acquisition is connect with the output end of control device with solenoid valve, the data
Acquisition and control device include receiving unit, compared with computing unit and control unit, receiving unit reception temperature sense
The observed temperature that device is sent, the computing unit that compares is by observed temperature and the preset temperature phase in pre-set insulated cabinet
Than difference being calculated, described control unit controls solenoid valve and opens, the chamber in cavity and refrigerator in insulated cabinet described in connection
Body, until the temperature in the insulated cabinet reaches preset temperature, described control unit controls solenoid valve and closes.
The beneficial effect that band of the present invention can write the programmed cooling instrument of cooling process is, it is only necessary to set in existing refrigerator inside
Insulated cabinet is set, and connects or disconnects by solenoid valve the cavity in cavity and insulated cabinet in refrigerator, utilizes the low of refrigerator
Temperature come in the cell and biological material containers in insulated cabinet cell or biomaterial cool down；Solenoid valve opens and closes
It is acquired by data with control device and is controlled, temperature inductor surveys the temperature of object to be cooled down, and comparing computing unit will receive
Difference is calculated compared with the preset temperature in pre-set insulated cabinet in the observed temperature that unit receives, and control is single
Member control solenoid valve is opened, the cavity connection of insulated cabinet and refrigerator, and temperature decline is accelerated in insulated cabinet, until the temperature in insulated cabinet
Degree reaches preset temperature, and described control unit controls solenoid valve and closes, insulated cabinet and ultra low temperature freezer inside cavity cold air every
From temperature decline slows down.It is able to cooperate existing ultra low temperature freezer to use, is not required to additional purchasing procedure cooling instrument and liquid nitrogen, it can also be right
The advantages of cell and biomaterial are programmed according to specific requirements, cost is relatively low.
Preferably, the data acquisition is arranged outside refrigerator with control device.It operates and observes convenient for user.
Preferably, the solenoid valve is butterfly-type solenoid valve, and for other solenoid valves, aperture is big, and structure is simple,
In the case where the no pressure difference of valve both ends, it can also work normally.
Preferably, the refrigerator is ultra low temperature freezer/low temperature refrigerator.The temperature of ultra low temperature freezer is -80 DEG C.
Preferably, the temperature inductor uses thermocouple.Compared to bi-metal temperature inductor, electric thermo-couple temperature detects model
It encloses greatly, detection is accurate.
