Detailed description of the invention
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
In embodiment as shown in Figures 1 to 7, a kind of culture carrier structure, including base 1 and the training of some upper end open Supporting vessel 2, each culture vessel stacks gradually from the bottom to top, a culture vessel contact base of bottom, and described base sets Having fixing vertical rod 11, culture vessel lateral wall is provided with and fixes the retaining collar 21 that vertical rod is adaptive, and retaining collar is set in solid Determining in vertical rod, culture vessel includes ware body 2a, the column 2b being arranged on the interior bottom of ware body and is arranged on ware body sidewall and inclines The liquid injection pipe 2c tiltedly arranged, the equal opening of column upper/lower terminal, the rotation pipe 3 of a vertical layout through all columns, described turn Dynamic pipe can relatively rotate with column, and is in sealing contact between rotation pipe lateral wall and column medial wall, rotates and sets on pipe lateral wall Have and run through the sump pit 31 rotating pipe upper/lower terminal, in a culture vessel: be provided with equal with what portion in ware body connected on column Fluid apertures 22, is provided with cell filtration net in equal liquid hole, liquid injection pipe lower end connects with portion in ware body, ware body sidewall be provided with in ware body The tune amount transverse tube 271 of portion's connection, tune amount transverse tube is provided with the tune amount post 272 running through tune two pipe ends of amount transverse tube, tune amount post and tune Amount transverse tube is threaded, and tune amount post is coaxial with tune amount transverse tube, and tune amount post the inner is in ware body, and tune amount post outer end is in tune amount Outside transverse tube, tune amount post sidewall is provided with baseline trough and is in the alignment mark rod 28 outside tune amount transverse tube, and tune amount transverse tube is provided with base Quasi-bar 29.
Before test, each culture vessel can be stacked gradually placement from the bottom to top, and it is fixing vertical to make retaining collar be inserted in when placing Bar, make column set to rotating pipe outer (rotate pipe and the structure that rotates in pipe can pre-set) so that each culture vessel Can align, the culture vessel of top just covers the culture vessel of lower section.Then each liquid injection pipe is carried out liquid feeding and (adds liquid Body culture medium or culture fluid), without deliberately controlling liquid volume added during liquid feeding, as long as liquid level lid crosses equal liquid hole.All liquid feeding is complete Cheng Hou, turn rotates pipe, allows sump pit connect with each equal liquid hole, so that the liquid in each culture vessel can be from equal liquid hole stream Going out, in culture vessel, remaining liquid measure reaches consistent, turn can rotate pipe subsequently, allow sump pit leave equal liquid hole and (make it not connect Logical), the most just it is rapidly completed liquid feeding.And want to regulate in ware body if liquid measure, it is also possible to realized by turn tune amount post, And mode is the most various: as, before liquid feeding, tune can be measured post inwardly (outward) turn certain distance, the most whole liquid feeding walks Suddenly the liquid measure finally stayed in ware body (after the process utilizing equal liquid hole and sump pit to carry out discharge opeing terminates) after completing can reduce and (increase Add);And for example, after liquid feeding, sump pit is when connecting with equal liquid hole, tune can be measured post inside turn certain distance, continue to discharge A part of liquid in ware body, thus allow the liquid measure stayed in ware body reduce.In above-mentioned regulative mode, the latter is more commonly used, this It is because after once liquid feeding completes, is relatively time-consuming with the mode discharge opeing again drawn, topple over, and operation is the most pretty troublesome, but Discharge opeing, regulation is carried out by aforementioned manner, the most very convenient.And the fixing quantity mode of tune amount post displacement is the most Sample, gives one example: in the present embodiment, at the beginning, can allow alignment mark rod align with baseline rod, baseline trough remote with tune amount transverse tube Align from one end of ware body, can be set as reference position herein and (baseline trough can also be allowed to be aligned in other setting position, depending on making Depending on the considering when demand of used time, design), after liquid feeding, sump pit is when connecting with equal liquid hole, the often inside turn one of tune amount post Circle, alignment mark rod will turn one circle again align with baseline rod that (mark rod that aligns, the baseline rod person of being convenient to operation are carried out Observe and regulation), due to tune amount post inside turn one enclose after, stretch into the volume in ware body be definite value (this value design time just Have determined that), so the liquid measure discharged also is definite value.During additionally, cultivate, test, tend not to be that all tune fluid columns are all used Arrive, or each adjust fluid column turn distance can difference, this be in order to adapt to different sample (variety classes cell may needs not Same initial incubation liquid measure) or quickly provide different culture environment (to come with the identical or different cultivation liquid measure of cell types Carry out cultivating and subsequent measurements, Comparability test) and the structure that designs.It is noted that alignment mark rod is preferably provided at ware body Outward, because being once arranged in ware body, alignment mark rod easily produces impact to liquid level when rotating, and degree of regulation can be by certain Impact, and it is unfavorable for that observation (if culture vessel is opaque, then can cause not observing, if culture vessel is transparent, see Examine also not as align mark rod be arranged on ware external time convenient).
It is pointed out that cell to be cultivated can just be inserted culture vessel before adding culture fluid and (be needed to wait to cultivate Cell of short duration can leave culture fluid and non-inactivation or death), now owing to there being the existence of cell filtration net, cell will not flow out Culture vessel;Can also add at culture fluid, equal hydraulic control amount (i.e. carries out discharge opeing mentioned by equal liquid hole so that liquid in each ware body Measure consistent process) add cell to be cultivated afterwards;The culture fluid that band also can directly need to be cultivated cell is directly injected into training (test under this premise should not consider the impact of initial cell quantity, and owing to having the existence of cell filtration net, cell to support vessel Will not flow out culture vessel).Specifically can select according to test objective, demand.
Described liquid injection pipe upper end is provided with the lid 23 with liquid injection pipe threaded engagement, rotates and is arranged with for by the top on pipe The vessel cover 24 that seals of the upper end open of a culture vessel.Lid can block and rotate pipe and extraneous connection, vessel cover Can block a culture vessel of the top and extraneous connection, remaining culture vessel is then by a training nearest above self Support vessel to block and extraneous connection.Such that it is able to ensure that each culture vessel separates with the external world in cell cultivation, process of the test, Thus allow the present invention be applicable to the test being hedged off from the outer world under premise.
Described base includes matrix 1a and some support column 1b being arranged on below matrix, and matrix is provided with and runs through matrix The end through hole 1c on upper and lower surface, rotates pipe lower end and stretches in end through hole, is provided with and opening up connects fluid cylinder 12 below end through hole, Being provided with the bottom bracing plate 13 being connected with at least one support column below matrix, bottom bracing plate is provided with and connects cylinder adaptive bottom fluid cylinder Groove, connects and is in bottom fluid cylinder in a groove.The liquid discharged from sump pit can be reclaimed (fall into and connect fluid cylinder) easily, can avoid wave Take and avoid polluting to external world.
Described column includes cylinder and orifice plate 25, and cylinder lateral wall is provided with side opening, on a column: orifice plate is stuck in side opening In, it being in sealing contact between orifice plate and side opening hole wall, orifice plate is made up of with lower half plate mutually symmetrical with upper half plate, upper half plate and lower half Plate is formed in one structure, and equal liquid hole is positioned on upper half plate.In addition to equal liquid hole, orifice plate is laterally zygomorphic structure, consequently, it is possible to One piece of orifice plate can be achieved with the Liquid level of two kinds of differing heights, i.e. by orifice plate with upper half plate upper and lower half plate under form Snap in side opening, then through equal hydraulic control amount (i.e. carry out discharge opeing mentioned by equal liquid hole so that process that in each ware body, liquid measure is consistent) After, liquid level consistent with equal liquid hole lowest part (now equal liquid hole is in more than in the middle part of orifice plate) in culture vessel;And by orifice plate With upper half plate under, lower half plate snap in side opening in upper form, then liquid level and equal liquid hole lowest part in final culture vessel Unanimously (now equal liquid hole is in the middle part of orifice plate following).Furthermore, it is possible to orifice plate is overlapped in configuration more, between each set orifice plate, only has equal liquid hole Highly different, in so can be achieved with culture vessel, which liquid level is the quick control of the initial liquid measure of various differences (need, just Use in a set of orifice plate corresponding with this liquid level is snapped in advance the side opening of each culture vessel).
Being provided with core pipe 4 and some horizontally disposed diaphragm plates 32 in described rotation pipe, core pipe lower end is stretched in end through hole, core Being arranged with support ring 41 on pipe, support ring is higher than bottom core pipe and support ring is in end through hole, is provided with support seat in end through hole 14, support seat top and be provided with seat slot and the annular groove adaptive with rotating pipe lower end, contact seat slot bottom land bottom support ring, rotate under pipe End stretches in annular groove and rotates and contacts annular groove bottom land bottom pipe, rotates pipe and is rotatably assorted with supporting seat, core pipe through support seat and Core pipe is rotatably assorted with supporting seat, and diaphragm plate is set on core pipe, and diaphragm plate cross section is annular, rotates pipe, core pipe and each Diaphragm plate is all coaxial, and core pipe can relatively rotate with diaphragm plate, is in sealing contact between core pipe and diaphragm plate, diaphragm plate and rotation pipe Between seal fixing;
Diaphragm plate is provided with even lumen pore 321, and core pipe is provided with some hole sealing plates 42 for the company's of sealing lumen pore, hole sealing plate and tabula Plate one_to_one corresponding, in corresponding hole sealing plate with diaphragm plate: hole sealing plate is in above diaphragm plate, hole sealing plate bottom surface contact diaphragm plate End face;
Rotate and form quantitative chamber 3a between the interior adjacent two pieces of diaphragm plates of pipe, if rotating pipe to be provided with main feeding hole 33, quantitative chamber With pipe to fluid apertures one_to_one corresponding, quantitative chamber and culture vessel one_to_one corresponding, in corresponding quantitative chamber with culture vessel: on column Being provided with cylinder to fluid apertures 26, quantitative chamber is communicated to cylinder to fluid apertures by corresponding pipe to fluid apertures, pipe to fluid apertures and cylinder to fluid apertures all in Cylinder, and the pipe interconnected is coaxial to fluid apertures with cylinder to fluid apertures, cylinder feeding axially bored line level, quantitative chamber lowest part is higher than cylinder To fluid apertures lowest part, cylinder is higher than equal liquid hole highest point to fluid apertures lowest part.
When needing to carry out each culture vessel mid-term while, liquid feeding (adds new culture fluid, Ke Yiyu in incubation Initial incubation liquid kind, proportioning are identical, it is also possible to different from initial incubation liquid kind, proportioning) time, for each ware body, liquid The time difference that body adds is the least, and exopathogenic factor interference suffered during final mensuration is the least (to be preferably capable of being simultaneously introduced cultivation Liquid).But unless allow many people simultaneously to each culture vessel to carry out property while liquid feeding, and height to be ensured, can be only achieved more Preferably effect, and in practical operation, the feasibility of this mode is on the low side.And in this programme, first turn rotates pipe, allow pipe To fluid apertures with corresponding cylinder to stagger between fluid apertures (not connecting), then allow rotation pipe motionless, first turn core pipe (if rotate pipe with Between column, frictional force is sufficiently large, then can direct turn core pipe, now rotating pipe will not be driven;Rub between pipe and column if rotating Wiping power is limited, then can pinch rotation pipe on the other hand, another hands carrys out turn core pipe;The present invention design time, preferential former feelings Shape), drive hole sealing plate leave even lumen pore (allow shrouding not company of sealing lumen pore), then can carry out liquid feeding from rotating pipe top, cultivation Liquid through each even lumen pore, and can finally be full of all of quantitative chamber, then proceedes to make rotation pipe motionless, and turn core pipe makes envelope Orifice plate seals even lumen pore, cuts off, and each quantitative intracavity liquid measure is consistent between the most each quantitative chamber.Then turn pipe can be rotated, logical Cross diaphragm plate drive core pipe rotate together (diaphragm plate and to rotate between pipe be fixing, although can phase between core pipe and diaphragm plate To rotation, but owing to being in sealing contact between core pipe and diaphragm plate, therefore between core pipe and diaphragm plate, necessarily there is the power of compression mutually And frictional force, so if relatively rotating, need applying allow they external force in relative rotation.And only turn core pipe time, rubbing Under the effect of wiping power, diaphragm plate can rotate together with core pipe, so rotating relative invariant position between Guan Yuxin pipe), allow Pipe connects between fluid apertures to fluid apertures and corresponding cylinder, the most each quantitative chamber can give in corresponding ware body portion simultaneously, equivalent Liquid feeding, can thoroughly eliminate the interference factors such as the liquid feeding time started is inconsistent, liquid feeding duration is inconsistent during middle liquid feeding.This Outward, this programme except can be used for liquid feeding in mid-term it can also be used to initially time liquid feeding.And after having had support seat, arrange from sump pit The liquid gone out can first reach to support seat top, the most outwards flows down.
During it is noted that sump pit connects with equal liquid hole, pipe staggers between fluid apertures with corresponding cylinder to fluid apertures;Pipe is given Fluid apertures is with corresponding cylinder to when connecting between fluid apertures, and sump pit staggers with equal liquid hole.And through equal hydraulic control amount (i.e. mentioned by all Fluid apertures carries out discharge opeing so that process that in each ware body, liquid measure is consistent) after, in utilizing quantitative chamber to ware body, carry out the behaviour of liquid feeding During work (when turn rotates pipe), it is impossible to allow sump pit again connect with equal liquid hole, otherwise can cause leakage at sump pit (in ware body, liquid flows out from equal liquid hole, sump pit again), specific constructive form and mode of operation have a variety of, this measure two Example,
Example 1: in the circumference rotating pipe, sump pit, equal liquid hole, pipe are arranged along up time pointing needle to fluid apertures successively to fluid apertures, cylinder.
