Abstract
The utility model relates to a vacuum ventilating device of an anaerobic jar. The bottom of a box body is provided with a vacuum pump which is connected with a push sleeve installed on the box body, the push sleeve is movably connected with a push body arranged at the central position of the bottom of an anaerobic jar body, a push rod is arranged in the push sleeve and is contacted with a rubber sealing head arranged in a cavity of the push body, and the front end in the box body is provided with an air bag which is communicated with the push sleeve and the vacuum pump through a pipeline. The utility model has the advantages of simple structure, easy processing, low cost, easy operation and wide application and uses mixing air filled in bags without using any reducing agents, and the utility model only needs 0.5-1 minute to accomplish the ventilation for anaerobic environment caused by the anaerobic jar, and can be applied to the scientific research of clinical examination and teaching.
Description
Technical field
The utility model relates to a kind of anaerobic bacteria culture device.
Background technology
At present, relatively more classical in the world anaerobic bacteria culture method mainly comprises three major types.The one, anaerobism glove box method, this method can make separation of anerobe and culture identification whole process carry out in anaerobic environment, this method is effective, accuracy and repeatability are better, it is the recognized standard anaerobic bacteria culture method in the world at present, but this method apparatus expensive, the consumption gas mixture scale of construction is big, can not get promotion and application all the time at home.The 2nd, the jet biography pipe of Heng Gete method, this method can obtain culture effect preferably to strictly anaerobic bacterium, but this method apparatus expensive does not obtain promotion and application preferably in developing country yet.The 3rd, anaerobism pipe (being GasPak) method though this method is easy, though obtain certain popularization, does not obtain promotion and application widely yet in view of culture effect is not good.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, easily processing, anaerobic jar vacuum air-changing device with low cost.
In order to achieve the above object, the technical solution adopted in the utility model is: at bottom half vacuum pump is installed, vacuum pump by the road be installed in the top cover that casing is provided with above and be connected, the top cover joins with the acrosome activity of anaerobism tank body bottom centre position setting, in the cover of top push rod is housed, push rod be arranged on the endoceliac rubber seal head in top and collide and connect, casing Inner Front End position is equipped with airbag and is connected with top cover and vacuum pump by the road.
The utility model has the advantages that:
1, simple in structure, easily processing is with low cost;
2, easy and simple to handle, make the gas mixture that is packed in bag, need not any reductive agent, anaerobic jar causes anaerobic environment only to take time and can finish in 0.5-1 minute;
3, floor space is little, and only floor space is 0.2 square metre;
4, the utility model adopts packed mixed gas instead to mix gas cylinder, reduces operating process, reduces the experimental cost expense greatly;
5, the utility model is widely used, and can be suitable for Clinical Laboratory scientific research and teaching usefulness.

Fig. 3 is top cover, push rod, acrosome, a rubber seal connection diagram.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 3 as can be known, the utility model is in casing 1 bottom vacuum pump 2 to be installed, vacuum pump 2 by the road be installed in the top cover 3 that casing 1 is provided with above and be connected, top cover 3 joins with acrosome 5 activities that anaerobism tank body 4 bottom centre positions are provided with, in the top cover 3 push rod 6 is housed, push rod 6 be arranged on rubber seal 7 acrosome 5 chambeies in and collide and connect, casing 1 Inner Front End position be equipped with airbag 8 by the road with the top overlap 3 and vacuum pump 2 be connected.
On described and the pipeline that vacuum pump 2 is connected stopping valve 9 is installed.
The described pipeline that is connected with airbag 8 is provided with ventilation switch 10 and vacuum table 11.
Principle of work of the present utility model is:
This device produces negative pressure with vacuum pump, and vacuum meter makes anaerobic jar be in the perfect vacuum state as monitoring negative pressure index, utilizes the ventilation switch that the gas mixture in the airbag is sent into and makes it to cause anaerobic environment to be beneficial to the anerobe growth in the anaerobic jar.Push rod in the top cover that is provided with on the top intravital rubber seal head rest casing with the anaerobic jar bottom backs down, make it the interior gas of airbag by after reaching equipressure in the pipeline inflow anaerobic jar, take off anaerobic jar, passage made anaerobic jar reach sealing effectiveness at the bottom of caulking gum head rest spring was sealed the anaerobic jar jar automatically.
