Background technology
At present, life science begins to pay close attention to more and more the dynamic growth process of cell.This imaging that just need utilize the viable cell workstation to carry out the long time-histories of viable cell is observed, and wherein, culturing room is a very important basic link in the viable cell imaging research.At present, the cultivation cell that is installed on the microscope stage has replaced the box-type culture systems gradually, becomes the main flow culture apparatus of viable cell workstation.
At present, multiple cultivation cell is developed to satisfy the demand of different researchs, but there is following various defective, as: the compound cultivation cell that has multiple function is very expensive, and be installed in and be used for accurately controlling the localized piezoelectric ceramic device of Z axle on the Stage microscope size of cultivating cell is limited to some extent, therefore, the function and the price of cell cultivated in balance, and domestic researcher is the most normal, and what select for use is to cooperate the small enclosed that culture dish uses at the bottom of the disposable glass to cultivate cell.Described closed cultivation cell is embedded on the Stage microscope that is installed in inverted microscope in the piezoelectric ceramic device, is made of the structure of airtight chamber top cover and base two portions.During use, place disposable glass floor cells culture dish therebetween, and remain on the level that is fit to the cell growth by special controller adjusting room temp, CO2 concentration.Above-mentioned closed cultivation cell can satisfy basic experiment demand.But, when the experimenter need operate culture sample in experimentation, adding (medicine or meta-bolites) or change substratum etc. as reagent, the experimenter need open the cell top cover lid of opening culture dish again, and very inconvenience seems.Aforesaid operations not only can change pericellular environment, influences the process of growth of cell, also may change the position of original object observing at the removable cover period of the day from 11 p.m. to 1 a.m, causes the cell that can not find original observation, will greatly influence experimental result.
Summary of the invention
The purpose of this utility model is for overcoming the defective that prior art exists, a kind of dosing perfusion device that is used for closed cultivation cell being provided.This device just can be given the culturing cell dosing without uncap.
Particularly, the dosing perfusion device that is used for closed cultivation cell of the present utility model, it is characterized in that, make by cultivating cell ring support (1), culture dish annular support (2), small hose (3), fine steel tube (4), cultivation cell loam cake (5), culture dish loam cake (6), cultivation cell base (7), culture dish base (8), syringe (9) and porous steel pipe (10) combination.
In the utility model, between the loam cake (5) of cultivation cell and the base (7) ring support (1) is installed, the edge up and down of ring support (1) agrees with loam cake (5), the base (7) of cultivating cell respectively, cultivates on the little locular wall and holes, run through inside and outside making cell, small hose (3) penetrates from the hole;
In the utility model, culture dish is a culture dish at the bottom of the disposable glass;
In the utility model, ring support (2) is installed between (8) at the bottom of culture dish loam cake (6) and the ware, edge agrees with culture dish loam cake (6), base (8) respectively about it, hole on the wall, make the inside and outside perforation of ware, penetrate fine steel tube (4), the ware outside part of steel pipe (4) links with introducing the small hose (3) of cultivating cell, part bending at the bottom of ware in the ware.
In the utility model, during perfusion, corresponding straight two fine steel tubes (4) are installed, end respectively connects a porous fine steel tube (10), during dosing, the small hose (3) outside cultivating cell medicine is injected, medicine enters culture dish at last by flexible pipe (3) and fine steel tube (4), finishes the interpolation of reagent.
The utility model is used for the experiment that needs are changed whole liquid nutrient mediums, and this situation not only needs to realize bigger perfusion flow (having into has), requires perfusion to change the liquid process simultaneously and finishes in mode as mild as a dove, in order to avoid influence the process of growth of cell.In order to satisfy this demand, in the utility model, on the diametric(al) of the supporting ring support of culture dish (2), bore two holes, fine steel tube (4) is installed in a hole, influx as liquid nutrient medium, the spout of fine steel tube (4) as liquid nutrient medium installed in another hole, the responsible inflow and the effusive fine steel tube (4) that stretch in the culture dish will be bent downwardly to the bottom near ware, simultaneously, the end of fine steel tube (4) will respectively connect the porous fine steel tube (10) of a horizontal positioned, the process of changing liquid nutrient medium is finished in the mode of advection, can be avoided the generation of chemical gradient, drop to the influence of changing liquid nutrient medium process cell growth minimum.
Characteristics of the present utility model are:
Need not open and cultivate cell and culture dish, can not change under the cultivation cell interior environmental conditions, cell in the culture dish in the cultivation cell be carried out reagent add (medicine or meta-bolites) or change substratum, and can not influence the experimental observation before and after the dosing.
For the ease of understanding, below will describe in detail dosing perfusion device of the present utility model by concrete drawings and Examples.It needs to be noted, specific examples and accompanying drawing only are in order to illustrate, obviously those of ordinary skill in the art can illustrate according to this paper, in scope of the present utility model the utility model is made various corrections and change, these corrections and change are also included in the scope of the present utility model.
