Embodiment
Describe the embodiment of cell separation apparatus of the present utility model in detail below in conjunction with accompanying drawing, but the utility model is not limited to these embodiments.
Embodiment one
Shown in Fig. 1, Fig. 2, Fig. 4, Fig. 5, cell separation apparatus of the present utility model, comprises main shaft 1, is connected to main shaft 1 and the centrifuge arm 2 rotated around main shaft 1, is fixedly connected on the cellular segregation collector 3 of centrifuge arm 2 one end arranged transversely.
Skimmer 4 is provided with above the main shaft of cell separation apparatus, as shown in Figure 4,5, skimmer 4 comprise input duct 41, the admission chamber 43 be connected with input duct, fluid pipeline 42 and be connected with fluid pipeline go out sap cavity 44, admission chamber 43 with go out sap cavity 44 and be provided with infusion port.
As shown in Figure 2, cellular segregation collector 3 comprises the waste liquid chamber 34 that acquisition cavity 33 that liquid outlet 32 that the fluid inlet 31 that is connected with the infusion port 431 of admission chamber 43 is connected with the infusion port 441 going out sap cavity 44 is communicated with fluid inlet 31 is communicated with liquid outlet 32 and the filter membrane 35 be arranged between acquisition cavity 33 and waste liquid chamber 34.The diameter of the filter opening of filter membrane 35 is less than the diameter wanting isolated cell.
Further, skimmer 4 is positioned at directly over main shaft 1.
As shown in Figure 2, fluid inlet 31 and acquisition cavity 33 are positioned at the far-end of centrifuge arm 2, and liquid outlet 32 and waste liquid chamber 34 are positioned at the near-end of centrifuge arm 2, and that is to say that the position of acquisition cavity 33 is compared with the position in waste liquid chamber 34, the luxuriant central arm of acquisition cavity 33 2 is far away than waste liquid chamber 34.Like this, liquid flows to liquid outlet 32 from fluid inlet 31, is to flow from away from centrifuge arm 2 to nearly centrifuge arm 2 direction; Thus make when cell suspension arrives acquisition cavity 33, while cell is isolated in acquisition cavity 33 by filter membrane 35, acquisition cavity 33 can be fallen to away from filter membrane 35 under the influence of centrifugal force, thus can not filter opening be blocked, filtration procedure be continued smooth and easy.Moisture content and the waste liquid such as biological particles and biomolecules are then because liquid stream pressure enters waste liquid chamber 34 by filter membrane 35.
As shown in Figure 4,5, the admission chamber 43 of skimmer 4 with go out sap cavity 44 and be separated, such as can be separated by sealing-ring 40, can prevent liquid from discharging via liquid outlet when just not entered out sap cavity when abundant centrifuging like this, and can make liquid enter cellular segregation collector by abundant centrifuging after discharge again; Further due to admission chamber 43 with go out sap cavity 44 and be separated, liquid to be filtered with filter after waste liquid can not be confused, effluent discharge while can be implemented in feed liquor filter liquide.
The input duct 41 of skimmer 4 and fluid pipeline 42 both also can be able to be collocated (as shown in Figure 4) by arranged coaxial (as shown in Figure 5).When adopting arranged coaxial, skimmer can be saved and taken up space; When employing configures side by side, the structure that can be easier to realize skimmer also can be cost-saving.By arranging skimmer, making liquid feeding end and outlet end be positioned at homonymy, the taking back and process of waste liquid can be realized better.
After adopting skimmer 4, time centrifugal, liquid to be filtered enters the admission chamber 43 of cell separation apparatus from input duct 41, cellular segregation collector is entered from the infusion port 431 of admission chamber 43, under the effect of centrifugal force and liquid propulsive force, the waste liquid filtered out enters waste liquid chamber 34 through filter membrane 35, enter out the infusion port 441 of sap cavity 44 by liquid outlet 32 thus enter out sap cavity, waste liquid collecting bag is flowed into again by fluid pipeline 42, therefore skimmer 4 be arranged so that waste collection process becomes simple, operator directly just can collect waste liquid up, such mode also saves the time, avoid contaminate environment simultaneously.And target cell is stopped by filter membrane 35 and throws away filter membrane 35 in the effect of centrifugal force and fall to acquisition cavity 33, like this, terminate centrifugal after, operator directly can take cellular segregation collector away and obtain useful cell.
Filter membrane 35 is hydrophilic filter film, and it adopts polyolefins or polyamide polymer to make.Preferably, filter membrane is made up of polyethylene or cellulose mixture or PE material or nylon material.The filter opening of filter membrane 35 is less than the size of the cell wanting separation and Extraction, thus the cell that must extract is isolated be deposited in acquisition cavity 33, and moisture content and other biomolecules flow to waste liquid chamber 34, then flow out from liquid outlet 2.Because general somatic size is 5-30um, therefore preferably, the diameter of the filter opening of filter membrane is 1-30um; More preferably, the diameter of filter opening is 1um-5um.
Preferably, in the present embodiment, the acquisition cavity of cellular segregation collector 3 be there is inner chamber and have certain thickness shape, the inner chamber of such as acquisition cavity is towards the diminishing shape in direction away from filter membrane, such as back taper, and its cross section can be square or circular, adopt such structure, because the centrifugal force farthest away from centrifugal shaft position is maximum, cell can be made to be deposited on acquisition cavity better, make it be not easy blocking to filter membrane hole place.
The feed liquor face of filter membrane 35 is positioned at centrifuge arm far-end, goes out liquid level and is positioned at centrifuge arm near-end.Centrifuge arm rotates and produces centrifugal force, thus makes the cell that stopped by filter membrane be subject to greatly larger centrifugal force and " being got rid of " from filter membrane because of its particle, maintains filter opening unobstructed, moisture content and useless or harmful biomolecules are flowed away by filter opening under hydraulic action.
Further preferably, centrifuge arm 2 length can be 10-30cm, and rotating speed can be 500-2000 rev/min, and the centrifugal force of generation can be 50-1000g; More preferably, rotating speed can be 500-1500 rev/min, and the centrifugal force of generation can be 100-700g.
In centrifugal process, owing to have employed the structure of skimmer, make whole cell separation apparatus be totally enclosed, feed liquor and fluid have special pipeline, can not pollute target cell, operate also very easy; Further, centrifugal process is dynamic centrifugal, can realize feed liquor, filter liquide effluent discharge on one side.In addition, the admission chamber in skimmer with go out sap cavity and be separated, after can making liquid to be filtered and filtering, waste liquid is separated completely, there will not be liquid not also to be filtered the situation of just being discharged by fluid pipeline.Under the influence of centrifugal force, useful target cell constantly gathers and not easily blocks filter membrane hole in the acquisition cavity 33 of collector.And waste liquid flows into waste liquid collecting bag by the fluid pipeline of skimmer, such mode also makes waste liquid comparatively easily collecting.
