Technical field
The utility model relates to a kind of device of food and medicine sanitary inspection, is specifically related to a kind of test tube for aerogens counting.
Background technology
Coliform means a group energy ferment lactose, produces sour aerogenesis, aerobic and amphimicrobian Gram-negative bactacin, be the monitoring of hygiene one of must micrometer biology.At present, its ordinary method is that common test tube or plastics tubing and Du Shi tubule are supported the use.Concrete method is: in common test tube or plastics tubing, add liquid culture medium, then Du Shi tubule is inverted in common test tube or plastics tubing, adds a cover stopper, after autoclave sterilization, inoculation sample, carries out coliform count check by observing Du Shi tubule aerogenesis situation.Adopt the drawback of aforesaid method to be: 1. the early-stage preparations of coliform count check are complicated, after autoclave sterilization, in the time of need to waiting high voltage sterilizing device to naturally cool to room temperature, can take out, expend time in long, reduce checkability, because if discharge fast the gas in high voltage sterilizing device, caused high voltage sterilizing device internal gas pressure to reduce, the collection and confinement of gases that liquid nutrient medium bumping is produced cannot be discharged in Du Shi tubule, thereby causes erroneous judgement; 2. place Du Shi tubule scientific research personnel's operating skill be there are certain requirements, if place improperly, can make has bubble in Du Shi tubule, affects observations, easily causes erroneous judgement.
Publication number be the patent of CN103421684A for the problems referred to above, designed a kind ofly by Du Shi tubule and the fixing Quick test tube of outer tube wall, and capping is improved; Such scheme has solved the Placement Problems of Du Shi tubule, but adopts the Du Shi tubule of this fixed sturcture, after autoclave sterilization, can open sterilising plant after still needing to wait for naturally cooling; And enter after bubble in Du Shi tubule, be still difficult to remove, cause erroneous judgement; This structure also exists cleans difficult defect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of test tube for aerogens counting, and it adopts the inclined-plane that is integrative-structure with outer tube to replace Du Shi tubule, and simple in structure, bubble is easily discharged and easy to clean.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
For a test tube for aerogens counting, comprise the outer tube of lower end closed, on the inwall of outer tube, be fixed with downward-sloping catch, the projection of described catch on outer tube bottom surface accounts for 1%～99% of outer tube cross-sectional area.
Described catch and outer tube axis are 1～89 ° of angle.Preferably 60～80 ° of described angles.
The projection of described catch on outer tube bottom surface accounts for outer tube cross-sectional area preferably 20%～80%
In technique scheme, adopt downward-sloping catch to replace Du Shi tubule, in the formed space of inwall of this downward-sloping catch and outer tube, can observe microorganism aerogenesis situation.
The beneficial effect that adopts technique scheme to produce is: (1) the utility model adopts the catch fixing with outer tube, without technician, according to experience, places Du Shi tubule, has simplified trace routine, has reduced the requirement to testing staff's experience and technology; (2) while adopting the utility model to detect, preliminary preparation only need add substratum in above-mentioned outer tube, seal the rear directly sterilizing of lid, after autoclaving without waiting for naturally cooling, by can directly taking out and test after the mode fast coolings such as venting, even because entered bubble in catch and the formed space of outer tube wall, as long as inclination outer tube can be discharged bubble, greatly shorten detection time, improved checkability; (3) the utility model simple in structure, be convenient to clean, transportation, be suitable for scale operation and application.

Embodiment
Referring to Fig. 1 and Fig. 2, the 1st embodiment of the present utility model, its structure comprises the outer tube 1 of lower end closed, is fixed with downward-sloping catch 2 on the inwall of outer tube 1, and the projection of described catch 2 on outer tube 1 bottom surface accounts for 1%～99% of outer tube 1 cross-sectional area; Described catch 2 is 1～89 ° of angle with outer tube 1 axis.Projection at catch 2 described in more excellent scheme on outer tube 1 bottom surface accounts for 20%～80% of outer tube 1 cross-sectional area; Described catch 2 is 20～60 ° with the angle of outer tube 1 axis, preferably 30～50 °.
1 cross section of outer tube described in the present embodiment is circular, and catch 2 is tabular, and the free-ended edge of catch 2 is shaped form.In other embodiments, the free-ended edge of catch 2 can also be broken-line type or linear pattern.The height of described catch 2 coupling ends is not higher than the liquid level after the interior splendid attire 10mL of outer tube 1 liquid.Liquid level after the height of coupling end is higher than the interior splendid attire 10mL of outer tube 1 liquid, in the space that coupling end and tube wall form, air cannot emptying, cannot complete aerogenesis and observe and check.
Adopt the utility model, the shape of outer tube 1 cross section is unrestricted, can be circle, ellipse, tetragon or Polygons.
Described test tube also comprises the sealing cover coordinating with outer tube 1 port.
Use the present embodiment to the step of coliform system counting to be:
1. in outer tube 1, add liquid culture medium, the liquid level of substratum, higher than catch 2 vertex 0.3～3cm, seals lid;
2. test tube is carried out to sterilizing, after autoclaving, without waiting for naturally cooling, by modes such as venting, will after test tube fast cooling, can directly take out, inoculation sample;
3. the space observation aerogenesis situation consisting of outer tube 1 inwall and catch 2, intuitively fast for coliform count check.
If find bubble in the space forming at outer tube 1 inwall and catch 2 in 2. in step, can bubble be driven out of by the mode of inclination outer tube, avoid causing erroneous judgement.
Referring to Fig. 3 and Fig. 4, be the utility model the 2nd embodiment, different from the 1st embodiment is, described outer tube 1 cross section is square, the flap-like of catch 2, the horizontal plane of flap-like catch is connected with the inwall coupling of outer tube 1, flanging is free end, and free-ended edge is linear pattern.The projection of catch 2 on outer tube 1 bottom surface accounts for 65% of outer tube 1 cross-sectional area, and described catch 2 is 60 ° with the angle α of outer tube 1 axis.
To sum up, the space observation aerogenesis that uses the utility model to form by outer tube wall and catch, can be intuitively, fast for coliform count check, it is simple in structure, shortens the early-stage preparations time, that the later stage of avoiding cleans outer tube and Du Shi tubule respectively is loaded down with trivial details; And by inclination outer tube, can get rid of possible bubble in early stage, avoid erroneous judgement, improve the reliability of assay.
