Technical field
The invention belongs to the refrigeration field, relate in particular to a kind of monitoring system of cell profound hypothermia cold storage environment.
Background technology
Current, along with the high speed development of IT technology, radio-frequency communication technology, internet communication technology, digitlization observation and control technology, a brand-new rising industry---Internet of Things is just grown up fast in all trades and professions.
Cell technology, the high-end professional technique as association areas such as modern disease control, medical treatment, military affairs, scientific researches has become one of most advanced and sophisticated professional technique that influences national economy.Because cell technology is for the specific dependency of environment, cytoactive has special, professional requirement to environmental key-elements such as temperature, humidity, in the links such as the sampling of cell products, exploitation, production, transportation and storage, the key element that influences cytoactive for temperature, humidity etc. has extremely urgent, strict measurement and monitoring requirement.
Glassy state is a kind of existence of material, the material of this moment has certain shape and volume as solid, arrangement between the liquid molecule is just in order approximate again, is amorphous state or amorphous state therefore, is similar to the light transmissive material glass that we know; The sub-chain motion of macromolecule polyalcohol that is in this state is frozen, only allows undersized motion, so its deformation is very little, therefore is called glassy state; And change softness into when macromolecule polyalcohol and during the rubber-like solid, just be in rubbery state.So-called amorphous (Amorphous) is meant residing a kind of non-equilibrium, the non-crystalline state of material, preponderates and solute when keeping noncrystalline when saturation conditions, and the solid that form this moment is exactly an amorphous state; (Glass transitiontemperature Tg), is meant the temperature (as shown in Figure 1) when the transformation (glass transition) of amorphous food from the glassy state to the rubbery state to so-called vitrification point.
The biological material vitrified low temperature that grows up the eighties in 20th century is preserved; be cell and protective agent solution thereof to be crossed with enough fast rate of temperature fall be as cold as its glass transition temperature, and be cured as completely glassy state and with this glassy state method of long preservation at low temperatures.Avoid crystallization in this course inside and outside the cell fully, thereby avoided the various damages cause owing to freezing.People such as Papatz adopt the glycerine protective agent to realize the vitrifying of red blood cell suspension.People such as Fahy have inquired into the basic principle that vitrifying is preserved, and have described and how to have realized vitrified basic process.People's such as Rall mouse embryo vitrifying is preserved and has been obtained success.People such as Fuku have carried out the research of Change of Ultrastructure in vitrifying preservation and the preservation process to the egg mother cell of ox.
The profound hypothermia vitrifying storage of cell is the most advanced memory technology of current practicality, and its key element is that rate temperature change and temperature are steadily monitored.
Current, in exploitation, production, transportation and the storage process of cell products, a kind of method is to adopt the living environment of the mode pair cell of manual measurement, paper record to monitor, this class methods manpower consumption is big, measure error varies with each individual, immense papery data retrieval and analysis are difficult, for some cells (virus) with human body invasive, can't effectively reduce or remit the harm of the person.Second method is by using special equipment to carry out individuation, discrete preservation and monitoring, these class methods increase on the measurement consistency, but still need manual record and analysis, in addition because the stationarity and the restricted number of its sampled point do not possess flexibility in the practical application.
