It grows and constantly consumes Porcine HGF and waste liquid and be constantly discharged so that the Porcine HGF of the cell growth chamber contains
Amount reduces, so that the content of the Porcine HGF keeps in a certain range, can be improved cell culture effect.
In another embodiment of the present invention, the method also includes: by the culture solution delivery pump by culture solution with
The form of impulse wave flows through the culture solution channel, alternately changes so that the pressure difference inside and outside the hollow fiber conduit is positive and negative,
The pressure difference of the culture solution channel and the cell growth chamber is timing, and the culture solution in the culture solution channel enters described thin
Intracellular growth chamber, the gas volume of the pressure extension box are compressed into the pressure in the culture solution channel and the cell growth chamber
Balance;When pressure difference in the culture solution channel and the cell growth chamber is negative, the waste liquid of the cell growth chamber enters
The culture solution channel, the gas volume of the pressure extension box increase to the culture solution channel and the cell growth chamber
Pressure balance.Can promote the exchange of the culture solution and waste liquid, the consumption of less culture solution prevents from cell being grown in waste liquid
Advantageous nutriment it is rapidly losing.
Wherein, it should be noted that for different cell categories, the culture solution channel and the cell growth chamber it
Between pressure difference demand it is different, for example, the attached cell is compared with the suspension cell, since attached cell is attached to
On the tube wall of the hollow fiber conduit, can more or less blocking be generated to the exchange of culture solution and waste liquid, it is therefore, usually adherent thin
Born of the same parents cultivate when the culture solution channel 11 and the cell growth chamber 12 between pressure difference be slightly larger than suspension cell culture when
Pressure difference.
Wherein, pulse, which refers to the process of, rapidly returns back to its original state after a physical quantity is mutated in short duration.
Without limitation to the concrete form of the impulse wave, the impulse wave can be rectangular wave, can be sine wave, or its
The waveform of his shape.
In one embodiment of the invention, it is described culture solution is flowed through in the form of impulse wave culture solution delivery pump it is described
Culture solution channel specifically includes:
The culture solution delivery pump is controlled with the first pre-set velocity and the second pre-set velocity alternately to the culture perfusion
Side conveys culture solution.
In embodiments of the present invention, the culture flow velocity that the culture perfusion side is flowed through by controlling, can be to described
The pressure of culture perfusion side is controlled, and the pressure difference of the culture solution channel and the cell growth chamber is with the shape of rectangular wave
Formula variation, for the speed of the culture solution delivery pump in the wave crest of the rectangular wave, the pressure in the culture solution channel is greater than institute
The pressure of cell growth chamber is stated, culture solution enters the cell growth chamber up to pressure balance, then, the culture solution delivery pump
Speed be transformed into the trough of the rectangular wave rapidly, the pressure of the cell growth chamber is greater than the pressure in the culture solution channel
Power, waste liquid enters the culture solution channel until pressure balance.
Wherein, replace the frequency changed to first pre-set velocity and the second pre-set velocity without limitation, described first
The frequency that pre-set velocity and the second pre-set velocity alternately change can be determined by the cell category being inoculated with, due to different cells
Type, when culture required nutriment concentration therefore difference also has the exchange frequency of culture solution and waste liquid
Institute is different.
In one embodiment of the invention, the method also includes: every the first preset time, pass through first sampler
Detection is sampled to the culture solution for flowing through the culture solution channel, if Metabolites Concentration is more than or equal to the in the culture solution
When one preset value, then the waste liquid delivery pump is controlled by the controller and opened, the culture in the culture solution channel will be flowed through
Liquid drains into the waste tank.
During carrying out Cyclic culture to the cell by culture solution, as the growth of cell can generate largely
Metabolite is sampled detection by the culture solution flowed out to the culture solution channel, and when Metabolites Concentration is excessively high
Control loop circuit is closed, and the culture solution is drained into waste tank, can be timely updated to the environment of cell culture,
Improve the efficiency of cell culture.
In one embodiment of the invention, the method also includes: every the second preset time, pass through second sampler
Cell and culture solution to the cell growth chamber, which are sampled, detects cell density therein, if the cell density
More than or equal to the second preset value, then the Porcine HGF delivery pump antiport is controlled by the controller, it will be described
Cell delivery in cell growth chamber is into the cellular collector.
It is described reversed by the controller control Porcine HGF delivery pump in another embodiment of the present invention
Operating, by the cell delivery in the cell growth chamber into the cellular collector after further include: pass through the controller
The Porcine HGF delivery pump Positive work is controlled, is inoculated with carefully by the cellular collector to the cell growth chamber
Born of the same parents.In embodiments of the present invention, inoculating cell can also be carried out to the cell growth chamber by the cellular collector, promoted
The lasting culture of next wheel cells.
In one embodiment of the invention, the method also includes: every third preset time, controls first valve and open
It opens, the closing of exhaust valve opening and the second valve, portion caused by the cell growth chamber is discharged into the culture solution and is stored up
In tank.
By closing second valve, the portion that the cell growth chamber can be made to generate smoothly drains into described
It cultivates in liquid storage tank, and passes through the row of exhausting-gas hole of the culture solution tank top to outside.
Certainly, the method can also include: every the 4th preset time, by second sampler to the cell
The culture solution of growth chamber is sampled, and detects its Porcine HGF content, if the Porcine HGF content and first
Difference between the lower limit of preset range is less than or equal to the first preset threshold, then controls the Porcine HGF delivery pump and open
It opens, the Porcine HGF of the second predetermined amount is conveyed to the cell growth chamber by Porcine HGF storage tank, so that described
Porcine HGF content is maintained in first preset range.
It is exchanged as cell grows constantly consumption Porcine HGF and culture solution with the continuous of waste liquid, cell growth chamber
Porcine HGF content can reduce, detected by the Porcine HGF content to the cell growth chamber, in institute
Extraneous infection is completely cut off by shut-off valve when stating Porcine HGF content deficiency, it is raw that Xiang Suoshu cell growth chamber supplements steril cell
The long factor promotes cell to grow well.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
