In two neighboring culture vessel:The convex block of top culture vessel is at the bottom in the ware inverted draw cut of culture vessel.

Before experiment, one of bottom is set to train when each culture vessel can be stacked gradually from the bottom to top placement, and place It supports in the convex block insertion base inverted draw cut of vessel, the convex block of top culture vessel is made to be embedded in the ware inverted draw cut of lower section culture vessel, make to erect Outside jacket casing to rotation pipe(Structure in rotation pipe and rotation pipe can be pre-set), so that each culture vessel can be aligned And it is fixed, the culture vessel of top just covers the culture vessel of lower section.Then liquid feeding is carried out to each liquid injection pipe(Add in liquid Culture medium or culture solution), without deliberately control liquid volume added during liquid feeding, as long as liquid level lid crosses equal liquid hole.Whole liquid feedings are completed Afterwards, turn rotation pipe allows sump pit to be connected with each equal liquid hole, so that the liquid in each culture vessel can be from equal liquid hole stream Go out, remaining liquid measure reaches consistent in culture vessel, then can turn rotation pipe, sump pit is allowed to leave equal liquid hole(It is made not connect It is logical), liquid feeding has so just been rapidly completed.And can also be realized if liquid measure by turn tune amount column in desired adjusting ware body, And mode is very various:It such as, can be inside by tune amount column before liquid feeding(Outside)Turn certain distance, so then entire liquid feeding walks After the completion of rapid(After the process of drain being carried out using equal liquid hole and sump pit)The liquid measure finally left in ware body can be reduced(Increase Add);For another example, after liquid feeding, sump pit is with equal liquid hole when connecting, the inside turn certain distance of tune amount column can be continued to discharge A part of liquid in ware body, so as to which the liquid measure left be allowed in ware body to reduce.In above-mentioned regulative mode, the latter is more commonly used, this Once being because after the completion of liquid feeding, with the mode drawn, toppled over, drain is relatively time-consuming again, and operation is also pretty troublesome, still It carried out drain with aforementioned manner, adjusted, then it is very convenient.And the quantitative control mode of tune amount column displacement distance is also very more Sample is given one example:In the present embodiment, at the beginning, can allow alignment mark rod be aligned with baseline rod, baseline trough and tune amount transverse tube it is remote One end alignment from ware body, can be set as reference position herein(Baseline trough can also be allowed to be aligned in other setting positions, depending on making Depending on the considering when demand of used time, design), after liquid feeding, sump pit is with equal liquid hole when connecting, and tune amount column is per inside turn one Circle, alignment mark rod will turn one enclose and be aligned again with baseline rod(It is aligned mark rod, the baseline rod person of being convenient to operation carries out Observation and adjusting), after being enclosed due to the inside turn one of tune amount column, the volume stretched into ware body is definite value(This value design when just It has determined that), so the liquid measure of discharge is also definite value.In addition, when culture, experiment, tend not to be that all tune fluid columns are all used It arrives or each tune fluid column turn distance can be different, this is to adapt to different samples(Variety classes cell may may require that not Same initial incubation liquid measure)Or quickly provide different culture environments(With cell types with identical or different Culture liquid measure come Carry out culture and subsequent measurements, Comparability test)And the structure designed.It is noted that alignment mark rod is preferably provided at ware body Outside, because being once arranged in ware body, alignment mark rod easily has an impact liquid level when rotating, and degree of regulation can be by certain It influences, and is unfavorable for observing(It if culture vessel is opaque, then can cause not observing, if culture vessel is transparent, see Examine also not as good as alignment mark rod be arranged on ware it is external when it is convenient).

It should be pointed out that cell to be cultivated can just be placed in culture vessel before culture solution is added in(It needs to wait to cultivate Cell of short duration can leave culture solution and non-inactivation or death), at this time due to there is the presence of cell filtering net, cell will not flow out Culture vessel;It can also be added in culture solution, equal hydraulic control amount(Drain is carried out mentioned by equal liquid hole so that liquid in each ware body Measure consistent process)Cell to be cultivated is added later;Also the culture solution that band directly can be needed to be cultivated to cell is directly injected into training Support vessel(Experiment under the premise of this should not consider the influence of initial cell quantity, and due to the presence for having cell filtering net, cell It will not flow out culture vessel).It can specifically be selected according to test objective, demand.

The liquid injection pipe upper end is equipped with pipe lid 23 with liquid injection pipe thread fitting, is arranged in rotation pipe for by the top A culture vessel the vessel cover 24 that seals of upper end opening.Pipe lid can block rotation pipe and extraneous connection, vessel cover A culture vessel of the top and extraneous connection can be blocked, remaining culture vessel is then by a nearest training of itself top Vessel are supported to block and extraneous connection.So as to ensure that each culture vessel separates during cell culture, experiment with the external world, So as to which the present invention be allowed to be applicable to the experiment under the premise of being isolated from the outside world.

Core pipe 4 is equipped in the rotation pipe and several horizontally disposed diaphragm plates 32, core pipe lower end are stretched into the through-hole of bottom, core Support ring 41 is arranged on pipe, support ring is in higher than core pipe bottom and support ring in the through-hole of bottom, and support base is equipped in the through-hole of bottom 14, support base top is equipped with seat slot and the seat apical ring slot being adapted to rotation pipe lower end, support ring bottom contact seat slot slot bottom, rotation Pipe lower end is stretched into an apical ring slot and rotation bottom of the tube contact seat apical ring slot slot bottom, rotation pipe are rotatably assorted with support base, core pipe It is rotatably assorted across support base and core pipe with support base, diaphragm plate is set in core pipe, and diaphragm plate cross section is in circular ring shape, is rotated Pipe, core pipe and each diaphragm plate are coaxial, and core pipe can be relatively rotated with diaphragm plate, in sealing contact between core pipe and diaphragm plate, tabula It seals and fixes between plate and rotation pipe;

Diaphragm plate be equipped with even lumen pore 321, core pipe be equipped with several hole sealing plates 42 for the company's of sealing lumen pore, hole sealing plate and Diaphragm plate corresponds, in corresponding hole sealing plate and diaphragm plate:Hole sealing plate is in above diaphragm plate, and the contact of hole sealing plate bottom surface is horizontal Partition board top surface;

Quantitative chamber 3a is formed in rotation pipe between adjacent two pieces of diaphragm plates, it is fixed if rotation pipe is equipped with main pipe to fluid apertures 33 It measures chamber and gives fluid apertures one-to-one correspondence with pipe, quantitative chamber is corresponded with culture vessel, in corresponding quantitative chamber and culture vessel:It is perpendicular Cylinder is equipped with cylinder to fluid apertures 21, and quantitative chamber is connected to cylinder to fluid apertures by corresponding pipe to fluid apertures, and pipe is to fluid apertures and cylinder to fluid apertures It is cylinder, and the pipe interconnected is coaxial to fluid apertures with cylinder to fluid apertures, cylinder gives fluid apertures axis horizontal, and quantitative chamber lowest part is high Fluid apertures lowest part is given in cylinder, cylinder is higher than equal liquid hole highest point to fluid apertures lowest part;

The feed flow funnel 35 being threadedly coupled with rotation pipe is equipped at the top of rotation pipe.During each structure installation, cooperation, if Feed flow funnel can interfere, then can first unload feed flow funnel, after the completion of to be assembled, operation, put in back feed flow funnel, and after It is continuous to carry out subsequent operation.

When needs carry out each culture vessel mid-term liquid feeding simultaneously(New culture solution, Ke Yiyu are added in incubation Initial incubation liquid type, proportioning are identical, can also be different from initial incubation liquid type, proportioning)When, for each ware body, liquid The time difference that body adds in is smaller, and the interference of suffered external cause is also smaller when finally measuring(It is preferably capable of adding in culture simultaneously Liquid).But it unless more people is allowed to carry out liquid feeding, and to ensure height while property to each culture vessel simultaneously, can be only achieved more Ideal effect, and in practical operation, the feasibility of this mode is relatively low.And in the present solution, first turn rotation pipe, allowing pipe It is staggered to fluid apertures with corresponding cylinder between fluid apertures(It does not connect), then allow rotation pipe motionless, first turn core pipe(If rotation pipe with Frictional force is sufficiently large between column, then can direct turn core pipe, at this time rotation pipe will not be driven;If it rubs between rotation pipe and column It is limited to wipe power, then rotation pipe can be pinched on the other hand, the other hand carrys out turn core pipe;The present invention is in design, preferential former feelings Shape), hole sealing plate is driven to leave even lumen pore(Allow the sealing plate not company's of sealing lumen pore), liquid feeding, culture then can be carried out at the top of rotation pipe Liquid can pass through each even lumen pore, and finally then proceed to make rotation pipe motionless, turn core pipe makes envelope full of all quantitative chambers Orifice plate seals even lumen pore, separates between quantitative chamber each at this time, and each quantitative intracavitary liquid measure is consistent.Then can turn rotation pipe, lead to Crossing diaphragm plate drives core pipe to rotate together(It is fixed between diaphragm plate and rotation pipe, although can phase between core pipe and diaphragm plate To rotation, but necessarily there is the power compressed mutually due in sealing contact between core pipe and diaphragm plate, between core pipe and diaphragm plate And frictional force, so if relatively rotating, need to apply the external force that them is allowed to relatively rotate.And only turn core pipe when, rubbing Under the action of wiping power, diaphragm plate can together be rotated with core pipe, so relative position is constant between rotation pipe and core pipe), allow Pipe is connected to fluid apertures with corresponding cylinder between fluid apertures, at this time each quantify chamber can give corresponding ware body inside simultaneously, equivalent Liquid feeding can thoroughly eliminate during intermediate liquid feeding the disturbing factors such as the liquid feeding time started is inconsistent, liquid feeding duration is inconsistent.This Outside, this programme is in addition to can be used for mid-term liquid feeding, it can also be used to liquid feeding when initially.And after having support base, it is arranged from sump pit The liquid gone out can first reach at the top of support base, then flow down outward.
