A unit for generating flue gas and other experimental gases controlled by a gas flow controller is connected with pure air or pure oxygen controlled by the gas flow controller, and is contacted with a cell gas exposure experimental cavity through a gas manifold to convey the cell exposure gas with controllable concentration. One end of a waste gas emission pipe is connected with the cell gas exposure experimental cavity, and the other end of the waste gas emission pipe is connected with a waste gas treatment device. The utility model has the beneficial effects of providing the novel control device of cell exposure gas with controllable concentration, randomly adjusting the concentration and oxygen content of the exposure gas, being used by exposure experiments to complete various cell exposure gas experiments, and controlling the whole process of the experiments. The control device of cell exposure gas with controllable concentration can be widely applied to special exposure gas cell experiments in medicine, public health environment, molecular biology, cytology, toxicology and other fields.
Description
Technical field
The cellular exposure that the utility model relates to a kind of controlled concentration is with gas control system device.
Background technology
The cell toxicology experiment has remedied many weak points that traditional animal gaseous state exposes experiment, but expose in the process of experiement control device at the research and development gaseous state, how to control cellular exposure gas, make its accurate, even, as to continue generation and conveying, become a great problem.If this problem can not solve, make experiment lose the consequence of meaning with causing because of experimental result is inaccurate, will greatly restrict toxicologic development.
The utility model content
For addressing the above problem, the cellular exposure that the utility model provides a kind of controlled concentration is with gas control system device.This is a kind of new cellular exposure with gas control system device, can regulated at will exposes the concentration and the oxygen level of usefulness gas, makes and is used for finishing various types of cells and exposes and use the gaseous state exposure experiment for exposing experiment, and can control and test whole process.
For achieving the above object, the technical solution of the utility model provides a kind of cellular exposure of controlled concentration with gas control system device, comprises that the cell gaseous state exposes experiment chamber and cell cultures sap cavity, places the micropore lamina membranacea of experimental cell special use between these two cavitys.The pure air of experimental gas generating unit such as the flue gas by gas flow-control and gas flow-control or purity oxygen gas are connected jointly and expose the experiment chamber by air feed branch pipe and cell gaseous state and contact and carry the cellular exposure gas of controlled concentration.Exhaust emission tube one end exposes the experiment chamber with the cell gaseous state and links to each other, and the other end links to each other with emission-control equipment.
The micropore lamina membranacea that described air feed branch pipe height and cell gaseous state expose in the experiment chamber is close, and its bottom is the hydraucone shape.
Thief hatch is arranged at described air feed branch pipe top.
The cellular exposure that its beneficial effect has provided a kind of new controlled concentration is with gas control system device, can regulated at will exposes the concentration and the oxygen level of usefulness gas, makes and is used for finishing various types of cells and exposes and use the gaseous state exposure experiment for exposing experiment, and can control and test whole process.The special use that can be widely used in each field such as medical science, public hygienic environment, molecular biology, cytology, toxicology exposes gaseous state cell exposure experiment.

Embodiment
In conjunction with the accompanying drawings the utility model is illustrated.
As shown in drawings, this device comprises that the cell gaseous state exposes experiment chamber (9) and cell cultures sap cavity (6), place the micropore lamina membranacea (7) of experimental cell special use between these two cavitys, the pure air of experimental gas generating unit (1) such as the flue gas by gas flow controller (10) control and gas flow controller (10) control or purity oxygen gas (11) are connected jointly to expose by air feed branch pipe (2) and cell gaseous state and test the contact cellular exposure gas of conveying controlled concentration of chamber (9).Air feed branch pipe (2) height is close with the micropore lamina membranacea (7) that the cell gaseous state exposes in the experiment chamber (9), and its bottom makes the cell gaseous state expose the abundant exposing cell upper surface of interior gaseous substance in experiment chamber (9) for hydraucone (8) shape can fully cover micropore lamina membranacea (7).Thief hatch (3) is arranged at air feed branch pipe (2) top, is convenient to collected specimens analysis at any time.Exhaust emission tube (4) one ends expose experiment chamber (9) with the cell gaseous state and link to each other, and the other end links to each other with emission-control equipment (5), and emission-control equipment (5) can fully absorb virulent exposure gas and reach safe and harmless discharging.
When using, at first open cell gaseous state exposure experiment chamber (9) the cultured micropore lamina membranacea (7) that has experimental cell is covered completely cell gaseous state exposure experiment chamber (9) after being placed under the aseptic condition on the cell cultures sap cavity (6), steadily putting well.Regulate gas flow controller (10) then, open experimental gas generating unit (1) or specific source of the gas and pure air or pure oxygen gas (11) simultaneously.Two kinds of gases import air feed branch pipe (2) simultaneously and are transported to the upper surface that spreads in experimental cell in the cell gaseous state exposure experiment chamber (9) uniformly experimental cell is carried out gaseous state exposure exposure experiment.The experiment while, experiment waste gas is input in the emission-control equipment (5) by exhaust emission tube (4) and purifies, and safety dumping.Pair cell exposure usefulness gas is sampled if desired, can be sampled by the thief hatch (3) on the air feed branch pipe (2).
Claims (3)
1. the cellular exposure of a controlled concentration is with gas control system device, it is characterized in that: comprise that the cell gaseous state exposes experiment chamber (9) and cell cultures sap cavity (6), place the micropore lamina membranacea (7) of experimental cell special use between these two cavitys, the pure air of experimental gas generating unit (1) such as the flue gas by gas flow controller (10) control and gas flow controller (10) control or purity oxygen gas (11) are connected jointly to expose by air feed branch pipe (2) and cell gaseous state and test the contact cellular exposure gas of conveying controlled concentration of chamber (9), exhaust emission tube (4) one ends expose experiment chamber (9) with the cell gaseous state and link to each other, and the other end links to each other with emission-control equipment (5).
