Description
Technical field
The utility model relates generally to a kind of liquid microbe trap setting, especially a kind of small volume, suitable for without dynamic
Power, the device of microorganism capture is carried out under the microgravity environment of no purity requirements.
Background technology
Microorganism is captured using the method for membrane filtration, is widely used in the microorganism detection of liquid or degerming mistake at present
Filter.Current film filter needs to use under clean or specific environment, and the microorganism that otherwise may be contained in air is dirty
Dye, and the collection of liquid needs to concentrate on filter membrane surface under Action of Gravity Field and could be filtered dry completely.And under microgravity environment, liquid
Filter membrane surface can not be concentrated on automatically, therefore can not be filtered dry, and the liquid internal not being filtered dry may contain micro- life of detection in need
Thing, so as to lead to not accurately detect, in addition, liquid can also influence the culture and observation in later stage.And the working environment of microgravity
It is difficult to provide clean environment and is operated, needs to take film to be attached on agar plate after plain filter filtering and cultivated, and
Under the non-clean environment of microgravity, agar plate can not be prepared and microorganism detection result can be influenceed by environment.
The content of the invention
The utility model is solves the problems, such as that prior art exists in use, there is provided it is a kind of can be in the non-clean of microgravity
The device of microorganism capture is carried out under net environment.
The utility model solve existing issue technical scheme be：A kind of liquid microbe trap setting, including filter,
Filter membrane is provided with filter, filter is provided with inlet, liquid outlet, as an improvement, upper wall and filter membrane in described filter
Between be provided with appropriate spacing, it is described appropriate to be smaller than being equal to absorption and converge at filter upper wall to form water droplet lower section lucky
Contact to filter membrane and microorganism grows into the distance of bacterium colony enough.
As a further improvement, the spacing between described filter membrane and filter is 0.5-2mm.
As a further improvement, water influent pipeline more than described filter inlet connection two-way or two-way；Above-mentioned
Filter upper surface flat transparent.
As a further improvement, described filter membrane bottom is provided with absorption pad.
As a further improvement, also include the cap stopper for being arranged at inlet and liquid outlet.
As a further improvement, described filter, which is provided with positioning, places cap stopper fix bar.
As a further improvement, described water influent pipeline is equipped with cap stopper.
Inhaled as a further improvement, also including one or more fluid injection to filter or/and from filter downstream
Take the syringe of liquid.
As a further improvement, syringe of the described syringe for not co-content.
As a further improvement, also include the peristaltic pump in connection liquid outlet downstream.
Compared with prior art, beneficial effect is will to be set suitably between upper wall and filter membrane in filter to the utility model
Spacing, this, which is suitably smaller than converging at filter upper wall equal to absorption, forms below water droplet contact just to filter membrane and foot
Enough microorganisms grow into the distance of bacterium colony.Filter is designed as totally enclosed flat structure, filter process by the appropriate spacing
In will not be influenceed by external source air.Its simultaneously the appropriate flat space of spacing it is possible to prevente effectively from liquid dissipates under microgravity
Excessive or balling-up.Culture medium can be added after the completion of filtering into catcher, culture medium is absorbed using absorption pad and nutrition is provided caused
The microorganism captured on filter membrane grows and forms bacterium colony, filter upper surface flat transparent, can observe result after incubation and count
Number, can be used for filtered fluid to remove microorganism or impurity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model filter.
Fig. 3 is the enlarged diagram at Fig. 2 a.
Fig. 4-6 is a kind of case study on implementation of the present utility model respectively.
Embodiment
Referring to Fig. 1-6, the utility model includes filter 1, is provided with filter membrane 2 in filter 1, filter 1 is provided with feed liquor
Mouthfuls 11, liquid outlet 12, appropriate spacing is provided between upper wall 21 and filter membrane 2 in filter 1, is suitably smaller than being equal to absorption and converges
Contact just is formed below water droplet in the upper wall 21 of filter 1 to filter membrane 2 and microorganism grows into the distance of bacterium colony enough, this
Sample can effectively ensure that can also filter even if micro liquid from filter membrane 2, avoid liquid from dissipating excessive or balling-up under microgravity.Specific filter
Spacing between film 2 and filter 1 is 0.5-2mm, spacing can be arranged into 0.5mm, 1mm, 1.5mm according to different liquids, most
It is no more than 2mm greatly.The bottom of filter membrane 2 can be provided with absorption pad 3.Also include the cap stopper 6 for being arranged at inlet 11 and liquid outlet 12.Filtering
Device 1 is provided with positioning and places the fix bar 13 of cap stopper 6.The upper surface flat transparent of filter 1, for observing or counting.
For the ease of micromanipulation, in addition to one or more fluid injection is to filter 1 or/and under filter 1
The syringe 5 of liquid draw is swum, syringe 5 may be configured as the syringe of one or more volumes, and syringe 5 is mainly used in filtering
Pressure or negative pressure are produced in device 1, liquid is also filtered under micro situation.
Inlet 11 is connected using syringe 5, in the upstream press filtration liquid of inlet 11, is completed after filtering from upstream annex solution
