A kind of operation device cultivated for cell
This utility model relates to a kind of operation device cultivated for cell, belongs to field of cell culture.
Cell culture bags, because its gas exchange area is big, closure is strong, cell proliferation is very fast, be difficult to the advantages such as pollution, is subject to
Favor to cell culture technology personnel.But, when using cell culture bags to carry out cell cultivation, in supplementary culture fluid process
Middle needs are connected with culture bag conduit by certain operation device, thus are joined in culture bag by culture fluid.Thin in reality
In born of the same parents' incubation, technical staff typically uses injector syringe to reach above-mentioned technique effect.But, injector syringe can carry
It is difficult to the problem such as liquid stream quantitative, uncontrollable, culture fluid hydrops residual, and syringe needle and push rod are also because not using
And waste therewith.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, it is provided that a kind of simple in construction, easy to operate thin
The operation device that born of the same parents cultivate, it is for supplementing culture fluid to cell culture bags.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
This utility model provides a kind of operation device cultivated for cell, it is characterised in that: described operation device is
Funneling, upper, middle and lower portion is sequentially provided with the adding mouth of interconnection, liquid storing barrel and connector.
The diameter of described adding mouth is more than described liquid storing barrel, can add to described liquid storing barrel conveniently by described adding mouth
Described liquid storing barrel sidewall has volume markings, described volume markings to may determine that fluid replacement volume.
Described liquid storing barrel bottom is funnel-form inclined-plane, can avoid culture fluid hydrops residual in liquid storing barrel.
Described liquid storing barrel and described connector connecting place are provided with rotary switch, and described rotary switch can control in liquid storing barrel
Flow rate of liquid.
Described connector matches with the conduit of cell culture bags, can be conveniently by conduit by described liquid storing barrel
Culture fluid adds in cell culture bags.
In this utility model, described adding mouth is relatively large in diameter, and can topple over cultivation conveniently by it to described liquid storing barrel
Liquid；Described liquid storing barrel sidewall has volume markings, it is achieved the accurate quantitative analysis to amount infused；Described liquid storing barrel bottom is that funnel-form is oblique
Face, makes liquid can be flowed completely out by described connector, it is to avoid hydrops；Described liquid storing barrel is provided with described connector connecting place
Rotary switch, described connector matches with the pipe aperture of culture bag, controls flow rate of liquid, mends easily in culture bag
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Main Reference label declaration:
1-adding mouth, 2-liquid storing barrel, 3-connector, 4-rotary switch, 5-volume markings
Detailed description of the invention
In order to technical characteristic of the present utility model, purpose and beneficial effect are had clearer understanding, with initial reference to description
The technical solution of the utility model is carried out described further below by accompanying drawing, but it is not intended that implements model to of the present utility model
The restriction enclosed.
Present embodiments provide the operation device that a kind of cell is cultivated, in conjunction with accompanying drawing, this utility model is made furtherly
As it is shown in figure 1, this utility model is the operation device of a kind of cell culture bags fluid infusion, including adding mouth 1, liquid storing barrel
2 and connector 3；The sidewall of liquid storing barrel 2 is provided with volume markings 5；Above connector 3, the junction with liquid storing barrel 2 is provided with rotation
Button switch 4.
The operation device using above-mentioned cell to cultivate carries out the mode of cell culture bags fluid infusion and may comprise steps of:
When fluid infusion in cell culture bags, connector 3 is connected with the conduit of culture bag, closes rotary switch 4, from adding
Sample mouth 1 pours culture fluid into, utilizes liquid storing barrel 2 sidewall upper volume scale 5 accurate quantitative analysis；After liquid feeding, open rotary switch
4, culture fluid at the uniform velocity flows into culture bag, after the culture fluid in liquid storing barrel 2 all flows into culture bag, by connector 3 from culture bag
Conduit in take out, complete fluid infusion process.
It should be understood that those skilled in the art can be designed that a lot of other amendments and embodiment, these amendment and
Embodiment will fall within spirit disclosed in the present application and spirit.
More specifically, in the range of disclosure, drawings and claims, can be to the group of theme composite configuration
Parts and/or layout is become to carry out multiple modification and improvement.In addition to the modification that building block and/or layout are carried out and improvement,
