Abstract
The utility model discloses a bacterium gathering culturing device used for filtering gathered bacteria and culturing the gathered bacteria in the culturing device. A barrel body of the device is made of transparent material, which is convenient for observation. According to uses, the bacterium gathering culturing device is designed into bigeminal, triple and tetragenous structures, and each portion of samples can uniformly pass through each culturing device. The bacterium gathering culturing device can be matched with a peristaltic pump or a sucking pump, and the utility model is suitable for pressurization filtration or depressurization filtration; after filtration, culture mediums are injected, and bacterial culture can be carried out. The utility model can be used for the bacterium gathering cultivation of the samples and sterility tests, and can be also used for bacteria removal and particles removal for liquid samples.
Description
The utility model relates to the device of liquid filtering and microbial culture.
With the immediate prior art of the utility model be by I the development the patent No. be the colony culture device of ZL95203829.3.Its primary structure is that plastic casing and the millipore filtration that is assemblied in are wherein formed, and is the garden cylindricality, filter membrane be fixed on the cylindrical shell of device and bottom, between, with two four-way structures, three colony culture devices are connected in parallel.Device is through sterilising treatment, disposable use.Its principle of work is that injection port connection peristaltic pump makes device interior formation malleation or outlet connection off-gas pump make device form negative pressure, filters to collect bacterium, injects liquid nutrient medium then to scale, cultivates, and is used for the aseptic detection of liquid sample.
The problem that prior art exists is: 1. device can't be dismantled through bonding disposable use, can not use repeatedly; 2. device has only designed three connection structures, does not comprise bigeminy and tetrad structure, has limitation on using.
The purpose of this utility model provides a kind of liquid filtering and carries out the device of microbial culture therein, and satisfies the needs that use repeatedly.Device can be done the connection of bigeminy, three, tetrad form according to different purposes respectively and be filtered the collection bacterium.
For achieving the above object, the solution that the utility model is taked is: device is made up of transparent cylindrical shell, millipore filtration, sealing-ring and base, injection port that the top design of cylindrical shell is arranged side by side and ventilation mouth, millipore filtration is installed in the ventilation mouth, the injection port lower end prolongs and forms water dropper, outlet of base bottom design.Cooperate two kinds of branches between cylindrical shell and the base: 1. utilize tackiness agent bonding; 2. employing thread fit, the sealing-ring sealing can be assembled demolition repeatedly.According to different purposes, colony culture device can be done being connected in parallel of bigeminy, three, tetrad form with Y-tube, four-way pipe or five-way pipe.
Owing in the above-mentioned solution, adopt tackiness agent that cylindrical shell and base is bonding, be fit to disposable use.Use thread fit between cylindrical shell and the base, the sealing-ring sealing can be torn open repeatedly, be unloaded installation, reaches the purpose of using repeatedly.Utilize threeway, four-way, five-way pipe respectively two, three, four colony culture devices to be connected in parallel.The colony culture device that is connected in parallel can be implemented to filter the collection bacterium simultaneously equably, cultivates respectively then.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a colony culture device adhesion type longitudinal diagram
Fig. 2 is a colony culture device thread fit type longitudinal diagram
Fig. 3 is the utility model first example structure synoptic diagram
In longitudinal diagram shown in Figure 1, injection port 1 and ventilation mouth 7 are at the top of device, installation can intercept the millipore filtration 8 of bacterium in the ventilation mouth 7, injection port 1 lower end is a water dropper 2, cylindrical shell 3 is the transparent material manufacturing, scale 4 indication volumes are arranged on the barrel wall, and millipore filtration 5 is fixed between cylindrical shell 3 and the base 6.Sealing-ring 11 sealing is arranged, and by gluing place 10 gummeds between cylindrical shell 3 and base 6, base 6 and millipore filtration 5 are contacted to be fine and closely woven wire side 9, and outlet 12 is in base 6 bottoms.
In longitudinal diagram shown in Figure 2, tube structure is consistent with cylindrical shell 3 structures shown in Figure 1, and base is made up of screw thread outer ring 13, funnel 17 and screen cloth 16, and 13 respectively adorn a sealing-ring 14 and 15 with cylindrical shell contact part and funnel 17 and cylindrical shell contact part in the screw thread outer ring.Fig. 3 is the structural representation of first embodiment of the utility model, its using method is: the injection port 1 of two colony culture devices is connected with Y-tube 19, make two incubators be state in parallel, sealing ventilation mouth 7, the opening 18 of Y-tube 19 and sample mutually, connection, Y-tube 19 under creeping effect, sample from opening 18 in Y-tube 19 enters two incubators respectively, implement to filter by filter membrane 5, filtrate is discharged through liquid outlet 12.After finishing filtration, open ventilation mouth 7, sealing liquid outlet 12.Liquid nutrient medium is injected incubator to scale 4.Remove Y-tube 19,, cultivate detection then the injection port sealing.The detection disposable incubator that finishes is promptly discarded, and the incubator of Shi Yonging is unpicked and washed repeatedly, re-assemblies to reuse.
Second embodiment of the present utility model is as shown in Figure 3, changes Y-tube 19 into four-way pipe, and three colony culture devices are connected in parallel, and its using method is identical with first embodiment.
The 3rd embodiment of the present utility model is as shown in Figure 3, connects Y-tube at the liquid outlet 12 of two incubators of parallel connection, links to each other with off-gas pump again, carries out filtration under diminished pressure.
